Update 2018: Patch your poo poo if you can! Meltdown and Spectre are here... Update 08/31/2014: Haswell-E is here, pairing up to 8 Haswell CPU cores with the X99 chipset and quad-channel DDR4 memory. This platform is for people who really need 6+ CPU cores, >32GB of RAM, double the normal memory bandwidth, or 32+ PCIe lanes. Most people would be better served with a 4790K, especially for gaming. Update 05/02/2014: The first motherboards with Intel Z97 chipsets are now available early. They continue to use the LGA-1150 socket and support existing Haswell CPUs as well as the upcoming Haswell Refresh/Devil's Canyon models and next year's 14nm Broadwell CPUs. Z97 boards typically sport SATA-Express and many include NGFF/M.2 slots for SSDs. We will know more once chipset reviews launch next week. Update 06/01/2013: Haswell reviews are here, here is selected coverage from Anandtech: Anandtech: The Haswell Review: Core i7 4770K and i5 4560K Tested Anandtech: The Intel Iris Pro 5200 Graphics Review: Core i7 4950HQ Tested Anandtech: Intel's Haswall Quad-core Desktop Lineup Anandtech: Intel's Haswell Quad-core Mobile Lineup Anandtech: Intel's Haswell: An HTPC Perspective Update 10/05/2012: Anandtech has posted their Haswell architecture analysis. Update 04/23/2012: Anandtech has posted their Ivy Bridge Core i7 3770K review. Update 03/06/2012: Anandtech has posted their Ivy Bridge Core i7 3770K preview, also confirming the Ivy Bride launch has been pushed back until April 29th. 7-series motherboards will still be launching April 8th as scheduled. Update 01/31/2011: A defect has been found in the SATA controller of the Intel 6-series chipset that will require a recall and replacement of Sandy Bridge motherboards. From the Intel statement: Intel posted:SANTA CLARA, Calif.--(BUSINESS WIRE)-- As part of ongoing quality assurance, Intel Corporation has discovered a design issue in a recently released support chip, the Intel® 6 Series, code-named Cougar Point, and has implemented a silicon fix. In some cases, the Serial-ATA (SATA) ports within the chipsets may degrade over time, potentially impacting the performance or functionality of SATA-linked devices such as hard disk drives and DVD-drives. The chipset is utilized in PCs with Intel’s latest Second Generation Intel Core processors, code-named Sandy Bridge. Intel has stopped shipment of the affected support chip from its factories. Intel has corrected the design issue, and has begun manufacturing a new version of the support chip which will resolve the issue. The Sandy Bridge microprocessor is unaffected and no other products are affected by this issue. Update 01/05/2011: The NDAs expired early. Here are some reviews: Anandtech: The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested Anandtech: Intel’s Sandy Bridge: Upheaval in the Mobile Landscape HardOCP: Intel Sandy Bridge 2600K & 2500K Processors Review Here are the original preview articles: Anandtech: Intel's Sandy Bridge Architecture Exposed Anandtech: Performance Preview of Intel's Sandy Bridge On January 9th, Intel will launch their new Sandy Bridge processors, and with them usher in some of the most significant changes to the computing landscape we've seen in years. The CPU Oddly enough for a new Intel product, the CPU cores are perhaps the least interesting aspect of Sandy Bridge. The upshot is that Sandy Bridge is about 10% faster clock-for-clock than current Lynnfield Core i5/i7 CPUs using current code, and uses about 10% less power. Sandy Bridge combines the SSE4.2 instructions from the Nehalem Core i7s, the AES-NI instructions from the Gulftown Core i7 hex-cores that drastically improve encryption and decryption performance, along with new Advanced Vector Extensions (AVX) that improve floating point performance. Intel has also introduced a new "Level 0 cache" that caches decoded instructions, improving power-efficiency by saving the CPU from having to duplicate work. Intel has also connected all parts of the CPU together using a high-speed ring bus, which is interesting because it physically sits on top of the L3 cache, like a highway overpass, allowing high-performance connectivity without taking up any room. Turbo Boost has also been enhanced in Sandy Bridge. Previously, Turbo Boost allowed the CPU to overclock itself if some cores were idle, or if all cores were in use but the processor hadn't reached its Thermal Design Power (TDP) yet. Turbo Boost is now allowed to exceed the rated TDP for up to 25 seconds at a time, in order to more quickly finish tasks and return to an idle condition. The Anandtech Sandy Bridge architecture article goes into more detail about these and other changes. Graphics Update 01/05/2011: It turns out that only the K-series overclocking edition desktop processors will feature the Intel HD Graphics 3000 GPU with 12 Execution Units. All other desktop processors will have Intel HD Graphics 2000 with 6 EUs. All laptop processors are Intel HD Graphics 3000. For the first time ever, we have onboard graphics that that are faster than a dedicated graphics card. Sandy Bridge has a DirectX10 graphics core integrated into the processor that handily beats either a Radeon HD 5450 or Geforce G210, spelling the end of the line for low-end GPUs that aren't capable of decent gaming performance. Unlike the Clarkdale processors which had a separate graphics chip sitting next to the CPU on the same package, on Sandy Bridge the graphics core is integrated into the processor die, much like another CPU core. The graphics core also supports Turbo Boost, allowing it to be overclocked to improve gaming performance if the processor cores aren't fully using their power budgets. The graphics core runs at 850Mhz, and can turbo up to 1100-1350Mhz depending on model. There's some uncertainty on the graphics performance for desktop Sandy Bridge chips, as depending on the model, they come with a graphics core that either has 6 or 12 Execution Units, and it hasn't been confirmed how many units the chip Anandtech tested had. Laptop chips all have 12 EUs. Media Engine Update 01/05/2011: The media engine has been branded as Intel Quick Sync technology. Unfortunately, using this technology requires that the processor's on-die graphics be enabled and in-use. You can't use it if you have your own videocard. On the plus side, performance is very impressive, and video quality is almost as good as CPU-only encoding (from a crappy encoder, it's no x264). Quality is MUCH improved over GPU-based encoders. One very disappointing aspect of the graphics integrated into Sandy Bridge is that Intel, being a CPU company, has chosen not to support any general purpose GPU acceleration features, such as OpenCL or DirectCompute. This isn't just a lack of driver or SDK support, the GPU is almost entirely fixed-function, with a bare minimum of programmable functionality. As an alternative, Intel has provided a media processor that performs pure hardware decoding of high definition MPEG2/VC-1 (WMV9)/AVC (H.264) video. In addition, it offers pure hardware encoding of AVC (H.264) video. The idea is that you'll be able to transcode video faster, and with lower power usage, on the CPU using the media engine than you would using a program that supports nVidia's CUDA or OpenCL on a dedicated GPU. This does require that you use a program that supports the Sandy Bridge media processor, but it's expected that support will be integrated into programs like Cyberlink's Media Show Espresso at launch, allowing performance comparisons with CUDA. We also don't know what kind of video quality it will produce, but probably likely that it won't be quite as good as dedicated software encoders like x264. A New Kind of Overclocking Update 01/05/2011: Overclocking requires that you have a motherboard based on the Intel P67 chipset. Motherboards that support the on-die graphics (using the H67 chipset) cannot support overclocking. In Q2 Intel will release the Z68 chipset that supports the processor graphics, overclocking, and an unannounced feature called SSD Caching. In addition to the K-series processors that are fully unlocked, the other CPUs that support Turbo mode can be overclocked to 400Mhz beyond their highest supported Turbo speed. Unfortunately if you buy a K-series CPU you have to give up on Intel VT-d virtualization technology (you still get VT-x) and Intel Trusted Execution Technology support, but essentially no one uses these features on the desktop so it's not really a big deal, just annoying. Overclocking your K-series CPU to 4.4Ghz+ on air seems to be attainable for nearly everyone. A CPU's clock speed is its Front Side Bus (FSB) speed multiplied by a value conveniently called the clock multiplier. On Intel CPUs since the Pentium II, this multiplier has been fixed by Intel at the factory (except on the most expensive Extreme Edition processors). As a result, overclocking has been accomplished by raising the FSB speed, which is generated by a clock generator chip on the motherboard. On the Sandy Bridge processors, this clock generator is now part of the chipset, and its frequency is fixed by Intel and cannot be changed by more than about 5%. This means that overclocking as we know it is now impossible. However, realizing the value of overclocking to enthusiasts, Intel will now be releasing some processor models with an unlocked multiplier. These models will have a letter "K" at the end of the model number, and will come at about a 10% price premium. Additionally, current indications are that those processors which support Turbo Mode (the Core i5 and i7 series) can be forced to run at any of their available turbo bins. While not an end to overclocking, this does mean the days of buying the cheapest processor model and overclocking the heck out of it are now behind us. Other Platform Features Update 01/05/2011: The Intel Z68 chipset coming in Q2 supports the processor graphics, overclocking, and an unannounced feature called SSD Caching. I don't know if it supports PCI-Express port bifurcation (splitting the PCI-E x16 into two x8s), but I would expect it does. Sandy Bridge will use a new socket, LGA-1155, that is not compatible at all with existing motherboards and CPUs. The new motherboards feature Intel 6-series chipsets that support the new SATA600 interface on two of the 6 SATA ports (the other four are SATA300). Like the current Lynnfield processors, the CPU provides a PCI-Express 2.0 x16 connection that can be divided into two x8 connections for Crossfire/SLI, though like with Clarkdale motherboards based on the H6x-series chipsets that support the onboard graphics cannot divide this connection, so are limited to one graphics card. USB3.0 will not be supported by the chipsets, but Intel is considering making a third-party USB3.0 controller part of the reference motherboard design. Intel has upgraded the PCI-E 1.0 x4 "DMI" bus that connects the chipset to the CPU to PCI-E 2.0, doubling interface bandwidth to 2.0GB/sec in each direction. This should improve performance for SATA600 and USB3.0 controller chips on the motherboard, without requiring them to do bizarre things like cannibalize PCI-E 2.0 lanes from the graphics card to get acceptable performance. AMD's Response Anandtech: AMD Discloses Bulldozer and Bobcat Architectures at Hot Chips 2010 The Bulldozer architecture is AMD's answer to Intel's Sandy Bridge. Bulldozer is based on "modules" of two integer cores with shared floating point and other hardware. Intel's Hyperthreading Technology allows two threads to share a core for a very small cost in die area, and a performance improvement of about 10% on average. AMD's Bulldozer architecture actually allows two threads to execute simultaneously, for about a 50% increase in die area but with a potential 100% performance increase in the best-case scenario. The upshot is that while Sandy Bridge will be a quad-core processor that appears to Windows as 8 cores and performs like 4.4 cores, Bulldozer will be a quad-module processor that appears to Windows as 8 cores, takes up the space of 6 cores, and performs somewhere between 4 and 8 cores depending on the workload. While it's still too early to draw meaningful conclusions, it seems likely that Intel's solution will be faster and more power-efficient overall, but that AMD's will at least narrow the current performance gap, possibly take the lead in some heavily-threaded workloads, and will target a good price/performance ratio. Bulldozer will also feature an on-die AMD GPU that will likely be significantly faster and more capable than Sandy Bridge's graphics, rumors are that it will be a Radeon HD 5570-class GPU with 400 Stream Processors.

I hope that isn't a quote from IDF, because it definately isn't true. SandyBridge cache slices sit opposite cpu cores on the ring; i.e. the core and the cache slice straddle the ring interface. There's additional wires to let a core talk to this nearest slice directly without having to emit a ring transaction. The thing I always found interesting was that the 3d graphics unit could also use the L3 cache.

Actually, I'm guessing it will be an even mix at suppliers like Newegg, and heavily favor the normal versions at Best Buy and the like. 10% isn't much of a surcharge, but it's $20 wasted if you're not planning on overclocking. That's enough to people doing price comparisons to pick the cheaper option.

How can a mostly fixed function GPU be DirectX 10 compliant?

Sandy Bridge, AKA: finally a Intel GPU that is not to be avoided like the plague. Even so, I'm still not a fan of Intel GPUs but hopefully this would drive down the mobile midrange GPUs down. Desktop wise I don't see why anyone would even bother with SB if they have already have overclocked ~4GHz i7/5/3/C2Q/Phenom II CPUs.

This kinda pisses me off, however I think nowadays overclocking a video card's GPU is at least as important. That's probably why Intel's only selling the unlocked ones for 10% more. Watch someone find a way to unlock the low end models anyway, if anything just to say "I did it!".

This is definitely going to kick-rear end for the portable market; the i7 I have in my MBP is already pretty sweet w/ integrated graphics, but now you get somewhat speedier CPU, greatly improved GPU, and reduced power consumption! Woo! Question though, since I've just been sleeping through the Nehalem lifecycle: do the Xeons simply have the GPU portion disabled, or unconnected? I'd think it'd be kind of pointless for a 4-way Xeon machine to have 3 unused GPUs that the end-user still has to pay for.

Pretty Cool Name posted:We do I want a lovely graphics processor built into my CPU? lovely? As the OP said, this will seriously put a dent in the low-mid end graphics card sales. There'll always be the X-treme gamer bunch that will pay $400+ to have the fastest GPU hot off the assembly line, but for 90% of computer users, a dedicated graphics card is just one more thing to worry about breaking/compatibility issues. The minimal Windows 7 graphical eye-candy doesn't require much, and the 3D GUI revolution has yet to (ever) take a real hold. The fact that browsers are only just beginning to take advantage of the GPU for page rendering shows just how little super fast GPUs matter to most.

Ah this makes sense, thanks. I'm pumped for Sandy Bridge; my first machine was a Pentium (family), then my personal boxes have gone P3 1.11GHz -> C2D E6600. I think it's almost upgrade time, even though my E6600 still does everything I need. That's kind of the thing after the C2D IMHO; if you forget about games for a second, these newer CPUs aren't really opening too many new doors...they just help you get existing stuff done waaay faster. Which is great and all, but it's not like a night and day "holy poo poo I have a C2D, now I can actually finish encoding a H.264 movie in this lifetime!"

I think it's almost upgrade time, even though my E6600 still does everything I need. Yeah, I know what you mean. My C2D E8400@3.25 isn't setting any records, but that and a 1 GB Radeon 4850 let me do everything I want and pretty darn well. Just about the only things upgrading would do for me are speed up 5 DVD encodes a year, run Folding@Home faster, and getting an even greater excess of frames per second on the games I run, or maybe stabilizing newer/less-well-behaved games at 60 fps instead of 30. And I built this machine roughly two weeks after the E8400 came out. Even a now-entry-level 4 GB of RAM doesn't really hold me back on anything. Things have changed in ten years. No matter what I decide to do, I can manage it, and I can fit the pauses into times of my life when I'm doing other things anyway (or just multitask around it). I helped a family friend pick a new computer recently, jumping from a poorly-aging P4 Dell Dimension to a Core i5 entertainment laptop. What a difference that was. I don't think I'll ever experience something like that. Will we never again feel the thrill of a desktop or laptop upgrade with a significant boost in capability? Are we doomed forever to only get our "new toy" excitement when Apple releases their version of a previously unpopular product and revitalizes that market? ![]()

Once these start getting cheap enough to become the default (non-media) drives, we'll probably see all kinds of cool built in RAID/optimized to hell craziness.

We both have similar computers, but at a LAN if we both click Starcraft II at the same time his is up and running before mine even shows a loading screen. It's absurdly fast. Anand from Anandtech has noted that he has some of the old SSDs that were fast for reads but no good for multitasking in USB enclosures to do OS installs and that a SSD to SSD Windows 7 install is under 3 minutes from first boot to first reboot. Seek times may not seem like much, but apparently they add up pretty quickly as far as user experience is concerned, since a good SSD-equipped machine feels like it just has no delay.

I think for bulk storage, platter drives will be supreme for a while. There was a nice 2TB drive on Amazon.com for like 80$ the other day. The dollar : gigabyte ratio on that is insane. I'm also waiting for a reasonably priced 120+ GB SSD (I may be waiting for a while) for a boot and some app drive. Ive watched enough of those "boot windows and launch 150 program" videos to see how stupidly fast they are.

B-Nasty posted:Got SSD? Last de-rail: yeah, the storage market is currently where the "holy poo poo, night and day" difference is at, thanks to SSD. Don't have to worry about mechanical failure, you get bitchin' fast speeds, etc. On-topic: I really appreciate the built-in GPU because 1) battery life on portables should be far better, 2) integrated GFX that aren't awful, 3) when spec'ing out a "low-end" machine for grandman/business, you don't have to compromise and forgo Aero/future HW acceleration due to cost. You get that GPU with the CPU. Serious gamers can scoff at it, but to me, being able to just drop a CPU in a new build for the parents and know that I'm not closing doors to pretty GUIs is a pretty sweet side benefit (that you can get with either Intel or AMD now I suppose). The on-board GPU does eat a chunk of your system RAM though, correct? Or can mobo manufacturers slap 128MB/256MB of RAM on-board and wire that straight to the GPU? I think my AMD 780G-based mobo lets you choose between eating system RAM or some dedicated RAM on the mobo.

I recalled that earlier integrated graphics chipsets (like, 915GL or older), the loss of a chunk of your system RAM wasn't terrible, but rather there was a parasitic/general loss of memory bandwidth due to the GPU sharing some of that memory. Or maybe that was just in the silly Sandra synthetic memory benchmarks, which no one really cared about except in overclocking e-peen contests.

movax posted:Or maybe that was just in the silly Sandra synthetic memory benchmarks, which no one really cared about except in overclocking e-peen contests. That. We're talking about systems that just need to do the job "well enough". And since the memory controller is now moved in to the CPU and DDR3 is here, I seriously doubt memory bandwidth is going to be saturated in most configurations.

Alereon posted:The GPU in Sandy Bridge has shader support, it's fully DirectX10 compliant, hence why it can run modern games with decent support, they just made everything that COULD be fixed-function, to reduce power usage and complexity. Here's the page of the Anandtech article with details. It actually comes very close to executing DirectX10 API instructions directly, which is an interesting approach. Kind of annoying then that the article you quoted says the hardware is fixed-function only when they actually just meant no GPGPU support but still supports DirectX/OpenGL shaders.
