A New Kind of Overclocking

The change to overclocking is interesting. I assume that most retail processors will be sold as "K" models since 10% is a relatively small price to pay for the extra performance a knowledgable person can get out of it.

When I first read this paragraph I thought Intel would limit unlocked multipliers and overclocking in general to the completely unreasonably priced Extreme Editions.
Phew.

Haswell is shaping up to be very interesting, but I’m really curious what Broadwell will bring.
One CPU architecture spanning from 4W phones to 85W+ desktops sounds crazy, but at this rate anything is possible.

And I really don’t find Intels 17W IVB SKUs slow at all. Quite the opposite, a 2012 Macbook Air has more processing power than 95% of all non-gaming consumers need.

CES conference showed the new Ivy Bridge Y series, coming in at 7W
As the manufacturing process is maturing, we're seeing some pretty rad SKUs come out. I wonder what this means in context of the 8W Haswell demo last year. I'm not an engineer, but could this mean there could be a Haswell Y series running at 5W at this time next year?

Note that this is 7W SDP (Scenario Design Power). The TDP of these CPUs is 13W, the rest is just marketing fluff.

Install Windows posted:

An ARM version of a Macbook Air would be a lovely laptop that performs poorly and doesn't have the benefits of either the iOS or the OS X ecosystems, and would only have the dubious benefit of marginally better battery life.

Warning, wild offtopic speculation ahead
I think the more likely route is a Macbook Air that can be separated at the hinge, with a fully functional but even lighter iPad Air as the display and a powerful CPU/Battery/IO/Keyboard for heavy work as the (optional) "base" part.

It’ll take a few years until we get there but that seems to be the obvious solution to me, although I have no idea how it would work on the software/OS side of things. I find it unlikely that they would mix two different architectures in one device, though.

Intel open sourced their Broadwell GPU drivers. I expect they will be able to keep their +50% GPU performance per generation pace up.

quote:

The changes are massive and it's looking like the Broadwell graphics improvements will be astonishing and provide significant improvements over Haswell and earlier generations of Intel graphics.
While public details on Broadwell have been scarce beyond its 14nm fab process and new instruction set extensions, with the initial kernel driver code we have a feeling for Broadwell from the graphics side... Intel Broadwell graphics should be a terrific upgrade. Ben Widawsky in publishing the initial Broadwell support said, "Broadwell represents the next generation (GEN8) in Intel graphics processing hardware. Broadwell graphics bring some of the biggest changes we've seen on the execution and memory management side of the GPU. There are equally large and exciting changes for the userspace drivers."

Ben additionally said that the eigth-generation Broadwell graphics "dwarf any other silicon iteration during my tenure, and certainly can compete with the likes of the gen3->gen4 changes."

Can’t wait to see some benchmarks of this chip compared to the respective Maxwell parts.

re AVR54, apparently the fix is "a minor silicone tweak".

I set up a DS1515+ connected to a pfsense firewall and VPN into that with another pfsense box last December.
As far as I can tell all use the same C-2000 series CPUs so the race is on.

The 1515+ seems to have a 3 year warranty but the Netgate pfsense boxes only come with 1 year (which already expired). There is probably going to be a lot of bad blood if they just leave their customers SOL.
On the other hand every single
device they make is affected and they aren't making billions from other products like Cisco, so what else can they do. Wouldn't want to be in their shoes!

Vendors are now reacting to the 18-month timebomb errata. None of them are allowed to mention the component or company, Synology even had to pull a statement because they mentioned Intel.

Pfsense/Netgate vowed to replace all affected units within 3 years of purchase which seems fair.

Still, having a ticking timebomb as a firewall which is often a single point of failure feels bad.

Most companies are rolling out board level fixes/workarounds which allow the buggy processors to be used without the issue occurring. I'm not even sure if there's a newer stepping available at the moment?

A board level workaround has been identified for the existing production stepping of the component which resolves the issue. This workaround is being cut into production as soon as possible after Chinese New Year. Additionally, some of our products are able to be reworked post-production to resolve the issue.

C2000 series based products should be safe to buy in a few weeks, assuming you don't end up with old stock.

Their top stock cooler is also rated for 140W TDP and insiders have dropped info that the 1800X hits over 90°C around 4.0 Ghz on air so I'm expecting launch models >200W overclocked.

Netgate sent out an email regarding the Atom C2000 bug today. Looks like they were able to fix it with a BIOS update because their appliances don't use certain buses.

The update can be done remotely via SSH but requires somebody to plug it out and back in at the end of the process. That sure beats having firewalls suddenly die after a few months.

The article pretty much explains why it isn't likely to be real in the first couple of paragraphs. Pretty much the only reason the writer thinks it could be real is that they used an acronym of an upcoming microarchitecture in one of the drawings. It isn't really feasible with how chips are currently produced. Anyone buying them would have to get a lot of them, and you wouldn't be designing them off a website.

One of the purposes of patent drawings is to express some of the patent's embodiments (implementations). So saying a customisable chip could have the latest intel cores, FPGA... is for illustrative purposes. They need to say that it can everything, be customised however, and procured whenever to cover their bases. So going with a codename (which we've known for a year prior) for a something that isn't even out makes the most sense in that context.

This is like seeing that PS4 patent where you say 'Mcdonalds' to skip an advert, and extrapolating that Mcdonalds is so specific that there must be some deal in place for it to happen. So therefore it will happen.

14nm++ is claimed to offer 25% greater performance at a given power level than the unoptimized 14nm process first used to produce Broadwell and Skylake chips, or as much as 52% less power consumption for the same level of performance. In fact, Intel's projections show that the transistor performance of 14nm++ will actually exceed that of its first generation of 10-nm products. Expect to see 14nm++ underpin Intel's rumored Coffee Lake CPUs later this year.

I wonder if the Basin Falls line (Skylake-X/Kaby Lake-X) is going to use the same process.

Paul MaudDib posted:

Pretty obviously a TIM problem. There's been a background murmur about this since launch but it's blown up today for some reason. In most cases it gets worse over time, presumably as the TIM migrates out of contact with the surfaces or whatever. Heat often makes various things less viscous so the heavy overclocking that many 7700Ks undergo might be a factor as well.

First time I've heard of this problem but it should be easy to check by observing the behavior, delidding, applying new TIM and checking if it stops.

My 2013 Crystalwell rMBP had significant thermal issues with massive throttling (50% of nominal clockspeed on all four cores under load). I replaced the TIM which was a was a dry and crumbly mess and clock frequencies went back to 130% of nominal clockspeed at full load on all four cores.

As you mentioned the constant heat does deteriorate thermal interface materials over time and OEM pastes are often much worse than what you can get for aftermarket OC purposes. The case of my rMBP has a whiff off planned obsolescence about it but that's -material.
Did I mention that the newest MBPs have their chips and heatsinks attached to the rear of the PCB and repasting requires the whole logic board to be removed?

JnnyThndrs posted:

I thought the TIM wasn't a factor, since people who delidded still had the temp-spike problem, according to the article?

Huh yeah, I missed that part. Based on some user reports it spikes much faster than it should be possible given the specific heat capacity of a CPU cooler. If it isn't a TIM issue then perhaps a thermal sensor issue.

I'm kind of losing track of all the architectures and codenames.

How will the entry level "HEDT" Kaby Lake X CPUs compare to "Desktop" Coffee Lake?
Aren't those supposed to launch at roughly the core count (4-6C) at the same time?

Paul MaudDib posted:

Coffee Lake will supposedly introduce 6C to the consumer lineup, but it's limited to the standard consumer featureset (16 lanes, dual-channel RAM, etc). Also, 6-core non-hyperthreaded for some reason.

SKL-X is still the HEDT lineup. Quad-channel ram, between 6 and (reportedly) up to 12 cores, 44 lanes (only 28 on the 8-core and below), etc. My speculation is that it may actually end up being a "HEDT Kaby Lake" and end up clocking well, since Kaby Lake's main improvement was a slightly revised process and some iGPU features that won't be on the HEDT chips.

Kaby Lake-X is a 4C Small Kaby Lake on the X299 platform and retains most of the disadvantages of the consumer lineup (new socket doesn't put features there that aren't on the silicon), i.e. 2-channel memory and 16 PCIe lanes.

Basically if everything that is reported is true - there is now a crossover in the middle. You can get your 4C/6C on either the consumer platform or the HEDT platform. The HEDT platform is going to have better features and allow you a future upgrade path, but be more expensive.

Ok thanks, that clears things up.
KBL singlecore performance paired with 6C/12T and a halfway decent upgrade path to 10 cores/quadchannel sounds nice.
I hope that X299 idle power consumption won't be off the charts and perhaps for some comparable, unlocked and only slightly more expensive Skylake-W CPUs for ECC but who am I kidding...

Intel is preparing more Skylake-X CPUs to counter Threadripper, now with a rumored Core i9-7980XE with 18C/36T.

PCGH claims to know from a reliable source that the heatspreader on Skylake-X is not soldered, so the countdown to the first $2500+ Extreme Edition i9 killed during delidding starts now.

http://translate.google.com/transla...n&langpair=auto

At the risk of sounding like a broken record, just how big is the market for desktop users requiring 18 Cores at ~3 Ghz and without ECC RAM?
At this point it looks like AMD and Intel are just rebadging CPUs that they had to make for the server market anyway. I'd be much more interested in a highly binned 6-8C SKU at 5 Ghz (not that I'd buy one).
