movax posted: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. Systems shipping with 2gb of ram aren't going to be slowed in any real way by 6% of system ram being allocated to desktop composition. Once you're up to 4gb it doesn't matter in the slightest. You can have all the dedicated GPU ram in the world you want, but this thing isn't going to be powerful enough to drive anything with it so you might as well just use the system memory that is already there and if you want anything more intensive than Aero or Flash HW acceleration then get real dedicated graphics.

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.

Doc Block posted:Unfortunately there are a lot of businesses with no plans whatsoever to upgrade beyond XP in the immediate future. I'm guessing at some point a proper study about TCO for XP vs Win7 is going to come out factoring in all the man hours sunk in having tier 1 chase down the stupid viruses that would have easily been stopped by just having Win7 in place, it'll get hyped through a bunch of management tech rags, and then CTOs will start screaming about migrating. The only business requirement that is actually forcing people in to upgrading at this point is graphics design people and engineers/3d modeling. PC LOAD LETTER posted:This is certainly true right now, but in a few years or so maybe (maaaybe) not. It'd be nice to have a GPU in most every PC that would support GPGPU apps, it'd certainly help foster the development of GPGPU apps. Possibly, but there is a huge sector of their business customers that simply aren't going to see any use out of this and if dropping it means cheaper chips, they'll go that route because their workload is serial in nature and 2-4 cores is going to be enough to handle small spikes in load and background tasks while being responsive. Where are you going to shoehorn GPGPU support in to the Office suite besides Excel jockeys? Especially considering Microsoft is already trying to abstract heavy lifting there to a server cluster behind the workstation.

The E6600 has had a good service life though. Mine has been dutifully chugging away for 4 years now, it's really not surprising that my next upgrade is going to involve a total platform overhaul. In hindsight it really amazes me how much hardware requirements for applications stagnated over that period of time. Between purging of old hardware and greater adoption of .NET and the overhead it costs, they seem to be going up in earnest for the first time in years.

And two accessible PCI slots for my wireless card and sound card which probably means a full ATX board since my video card has a two-slot cooler. One more question, will that Cooler Master Hyper 212P work with the new socket 1155? Likely not, but you'll want one that lets you have granular control of voltages and the FSB along with ratio splits and all that other fun stuff. Just wait until they're out for a bit and see what people recommend because in addition to those features some boards will be better suited for going above spec ratings.

Hyperthreading isn't going to hinder performance, it just jams additional instructions in to holes in the execution pipeline when it finds them. Either one of two things will happen: Your game is single-threaded (or dual, triple threaded) and you have a core or more free to run background processes and the windows resource scheduler runs them on those because it sees cycles available there and hyperthreading doesn't really enter in to it, or you're doing something that consumes all your CPU cycles and your background processes are going to be in contention with your game/application and splitting resources according to the process priority while hyperthreading jams instructions in to those pipeline holes and gets more work done per clock than would have happened otherwise.

Lum posted:My main interest in EFI is to improve boot time. Sleep mode makes that pretty low on my consideration list these days. As for legacy stuff bogging it down, this will mostly depend on how it is implemented. If it is like what Dell did on their servers, the core will be EFI with BIOS emulation layers for legacy components but those can be turned off if not needed. Who knows how other manufacturers will handle it, though I suspect a lot will do a bad job initially.

Lum posted:Am I right in thinking that you need EFI drivers for add-in cards to avoid the BIOS emulation layer, and therefore I'll need to hold off on a graphics card update until they start supporting EFI too? No, it just uses some standard VGA 640x480 driver. Things like add-in disk controllers or network cards with PXE support are going to be the problem and forced through a legacy layer.

Odds are that yes, even a terrible EFI implementation will not be any worse than a standard BIOS one (unless they did a horrific job and there are stability/conflict issues). One of the things I really enjoy about EFI is that because there is so much more desktop area and storage to work with, not to mention mouse support, so you can get detailed feature descriptions on settings without having to dig out the manual or whatnot. Plus the potential for an embedded firmware flash utility that can use ftp to pull down the updated bin files, since there is a TCP/IP stack.

Idle quad-core i5 systems draw less power than the older Core2 systems that are replacing them in our office. They might draw more when under heavy load, but it is really going to depend on how you are using them and with what software.

movax posted:It's definitely a hard launch, but rest assured, Newegg and co. will gouge for a few weeks before prices settle. I'd be a little more worried about mobo availability, once the first few AnandTech/similar reviews come out recommending a certain board(s) at a certain pricepoint, they sell out reaaaaly fast. All the benchmarks I have seen indicate that dual vs triple channel isn't going to make a difference because your cpu can't use all that memory bandwidth. Once we start seeing 6 and 8 core i7's then it will probably matter, but not at the moment. Maybe you'll start hitting limits of a dual-channel config if you start really overclocking the hell out of it, but then you can just drop in that 3rd dimm and get ever more bandwidth. I seriously doubt it will provide any performance benefit to screw around with memory FSB until we start getting in to 6 and 8 core home systems.

What's the story with that low-overhead AMD AA tech (the one that messes with text fidelity)? Are there specific cards it works with or is it just a driver-based feature? I usually end up with nvidia cards but the 6850 is looking like a good deal and that feature is enticing.

The Radeon HD 6900-series also added Enhanced Quality AA, which takes additional coverage samples to improve color blending quality. Also, I'm not sure, but I think they may have fixed the AA messing with text by putting in application profiles that disables AA for apps like web browsers. Thanks.

Do you really need an extra 600mhz? The more voltage you crank through this thing, the shorter its lifespan will be and at some point you have to ask yourself if it is worth mucking around with any more.

MaxxBot posted:I understand your concern but 1.3V is by no means a high voltage for a 2500K/2600k CPU to run at. Mine is at 1.38V and it barely breaks 60C at full load. I understand there is more to this than temperature but people have even asked motherboard manufacturers and been told that voltages up to 1.42V are safe. People have stress tested these things for days with voltages over 1.5V with no issues. I'm not talking about life issues in days or months, I'm talking about the traces frying out after 2 years instead of 10. That's the risk you take by over-volting it and there simply isn't enough time to do load testing to recreate the potential loss in service life. If that isn't really a concern for you, then by all means go crazy. I'm trying to stress the point that just because it is stable, doesn't mean you aren't damaging things.

What kind of temperatures should I be seeing on a 2500k at stock speeds with the Intel cooler? It idles around 30C which seems well enough, but if I throw it under Prime95 for some load testing it shoots up to 60C+ and the fan RPM never budges from 2000. On my old E6600 the fan speed would start ramping up around 50C which seems right, 60C seems high to me.

Spread spectrum is off and I've reseated at this point. No idea about the BCLK, but I would assume it's still at factory settings. Like I said, I'm 90% sure it's just the video card being bad but the way the keyboard locks up when it happens makes me a little worried about the PCIe bus/chipset as well. I don't have enough hardware to do a proper bench test which is making this more difficult that I expected.

But if anyone has some crappy software that runs on a 1.3 JRE they could test I would appreciate it. The behavior is odd. Basically the windows won't refresh unless you move them.

Combat Pretzel posted:I wish SSD caching would be a function of the OS. Put it in the new Storage Spaces stack, or whatever. In ZFS it was called L2ARC and worked drat fine. I think the all-in-one approach Seagate is taking with their Momentus XT drives is the best long-term approach, but at the moment it is primarily doing read caching because they only have 16GB of SSD to work with (and a chunk of that is reserved for OS boot acceleration). If they start getting 32-64+ gb of SSD on there then instead of read acceleration it could become a two-stage storage mechanism where write data is also staged there as a NV cache similar to what high-end raid controllers and NAS's are doing.

Apple is looking long and hard at moving to Arm on their laptops for the power/weight benefits. The iOS-ification of OSX and channeling software through their app store is going to enable them to force 3rd party devs to re-write (assuming its needed) and compile for both Arm and x86 platforms in a laptop form factor without having to do the messy transition period for the user like what happened with Rosetta and the move to Intel. Intel knows this, and they're scared shitless at the prospect. I have a feeling if the transition does happen that the iMac and Mac Pro lines will stay on x86 for a lot longer than the mobile stuff.

Laptops don't bring in money for Apple like what iPhone/iPad does for them. That's in part because Intel processors and x86 in general costs a lot more than what Arm would cost. And Apple is already doing the move to in-house Arm design which is going to help drive down their part cost even more. Those things mean that switching their laptops over to Arm gives them bigger margins on those products in addition to greatly improved battery life. They're in business of selling products that make money, an Arm transition would give them that, so of course they are considering it if Intel can't follow through fast enough.

Peechka posted:Its funny you say this because I do a lot of CAD at home, especially when the deadline is nearing and I only have 30% of the work done.(I would rather do it at home than spend more time at work) My i5 2500K and 4 gigs of ram with a ATI5850 blows through the stuff just as fast as my machine at work that costs 4x as much. Well, maybe Im overstating this a bit, but still, my productivity does not suffer at all. No, that is the exact fight I had to have with our engineers a few years back and the results were the same as what you see. CAD and Revit are extremely CPU bottlenecked and single threaded. There are some switches you can throw in to make the normal operations spread over multiple threads, but the software is complete garbage and the feature is "experimental" and often leads to layers being displayed out of order because of thread synchronization issues so you can't really use it. A cheaper, dual-core processor on a Precision T1500 was a whole lot faster at all your normal work than a quad-core because those were invariably clocked slower making the per-core performance worse. Even the GPU load when you're working in large 3d models is jack squat and if you watch load through GPU-z you're lucky to see 10% utilization with maybe 25% vram usage. And that's with the absolute cheapest FirePro cards we could throw in the things to at least get "certified" drivers and support. Autodesk is just such a horrible shithole of a company and I swear they are in collusion with hardware vendors to sell their customers computers that cost 3-4x what they actually need to be spending to do the work. And god help you if you actually encounter a real bug that you need support on, because it's not getting fixed. We dealt with an issue for over a year on the 64-bit builds of their products certain systems if you rolled your cursor over an mpolygon the whole program would crash. Only on the 64-bit build, 32 wouldn't do it. And if you did a mass deletion of mpolygon objects on 64-bit it would take 20 minutes while pegging out an entire CPU core but if you did it on 32-bit it would be an instantaneous operation. I'm glad I don't support that poo poo any more.
