There's no currently-made air cooler that can handle that.

As for the Xbox/PS4 APUs, based on the reviews of Kabini, a Haswell i3 has the same fully-multithreaded CPU performance as the Xbox/PS4's 2-module/8-core CPUs. Rather than AMD having an advantage from increased threading, it's more like their extreme deficit in single-threaded performance may become less of a handicap.

Is there any reason AMD can't just go back to Phenom and start over, dropping the 2 integer cores per fpu stuff they did with Bulldozer? Besides their horrific financial situation and lack of manpower, that is. That's what I understand Intel did after netburst, so would it be possible for AMD to do that as well?

Speaking of which, why on earth did they choose to make such an insane bet with Bulldozer, that heavily multithreaded computing was the way of the future? By 2009 I think it was evident that it wasn't, they had 3 and 4 core processors and it's not like single core performance was rendered obsolete. Were they just tired of competing against the goliath that is Intel?

It's possible that they already have and we'll find out soon. Product cycles for CPUs are something like 4-6 years of development before there's something to sell. In the meantime, while that's happening, gotta make money.

I don't think 220W should be a problem for any high-end air cooler, Anandtech was able to do it on the AMD retail liquid cooler, which is equivalent to a Corsair H70. If you can do it on low/mid-range water, then an even more efficient high-end air cooler would be no sweat. Here's a comparison of the H70 and a high-end Thermalright Silver Arrow cooler, both with 2x120mm fans. Water coolers only start to have advantages over air when you can use double-length or larger radiators.

The HD5000 parts are a little off of the 650.

Does this make them not-gaming-grade? Well, they're a substitute at best if you have access and willingness for dedicated cards, but this isn't the end of the tape - the most demanding thing on Steam for Linux is Serious Sam 3, which a 5200 on 1866+ RAM can manage easily, (note that both of these may have changed recently - and it doesn't bode GREAT for Steam for Linux, what with its less than 150-title lineup) and Intel's Linux support is impeccable, mostly because they release their entire API and as much design as needed to not blow at drivers to the open-source community.

My only concern is that Valve saw a convenient place to jump into the console wars and bought up most of the production runs of HD 5x00-equipped processors.

One should remember that Intel didn't pull the core processors out of a hat after Netburst. They had been developing them for years prior and selling them as the Pentium M processors in laptops. The Dothan core was much faster per clock than the Netburst chips, and used a lot less power. Intel basically ran with their excellent mobile chips, they didn't have to go back to the drawing board so to speak.

Intel basically ran with their excellent mobile chips, they didn't have to go back to the drawing board so to speak.

It's more interesting than that, in my opinion - they basically saw AMD's strategy with the Athlon XP and then Athlon 64 chips, shorter pipelines with efficient execution and lower clock-rates as a result. I recall the Athlon XP Barton core had a 12-step pipeline, compared to a 30 or greater step pipeline for the Prescott P4s (which required the invention of a technology that would become very useful later, HyperThreading - back then, it was a desperate solution to the problem of wasting catches in the gigantic execution pipeline, slowing an already problematic execution system down even further... Now we enjoy it as a supplement to an efficient pipeline with effective hit vs. miss technology already in place and it just makes that even better).

Intel had a processor more or less like the Bartons already - the Pentium 3 (P6) - and making the Pentium M basically involved a lot of effective R&D on how to make the P6 into a (for the time) modern processor.

I'm kind of hoping that AMD has something like this going on with the K10.5 chips, but early results with the post-K10 Bulldozer alternatives were discouraging. Still, AMD just isn't in a position to sit stubbornly and hope that computing changes overnight to make their good multithreaded performance matter more than their poo poo singlethreaded performance, and nobody is interested in trying to deal with the heat and power requirements in higher end markets anyway. They don't have the clout to do what Intel did when faced with this problem, which was to force computer building companies to use their processors even though they sucked by making them offers they couldn't refuse. AMD's broke compared to Intel, that fine in the EU was a blip on the bottom line and nothing more. A moral victory counts for poo poo when your company is in the red and things are looking grim.

But it would be great to see them have some really competitive K10.5 derivative chip come out and be genuinely competitive against Intel's lineup. Even if it wasn't able to dominate, just getting something that doesn't suck at each price point except in the most multi-threaded things and without regard to efficiency would be fantastic. I miss the days when it made damned good sense to build an AMD-based computer, and they went from nothing to 25% server marketshare in the space of a couple years. I want to see them there again, for nostalgia and to give Intel a reason to innovate further and solve more than one problem at a time. And care about the little things, like appropriate spacing between the IHS and the CPU. For goodness' sake, it's a bad scene when something like that is just considered fine by them.

Intel had a string of remarkably well executed products post RDRAM and netburst: Conroe, Nehalem and Sandy Bridge. AMD's bulldozer was crippled by management turmoil and was released half baked. Piledriver was a nice improvement and I imagine steamroller with follow suite. AMD is more or less punting on the server/high end market until excavator it seems.

Being contractually wed to GloFlo has been a nightmare for AMD. Intel has done a remarkable job in continually optimizing their IPC, but the low hanging fruit is long gone and the move to 14 nm is a challenging one even for Intel. As GloFlo and TSMC get their 28 and 20 nm lines going, AMD has a shot at becoming more competitive vis-a-vis the i5, i3 and Atom. AMD does not have the resources to go after Intel on all fronts, so they have targeted desktop and tablet APUs as well as the microserver market as niches to exploit with keveri, kabini, temash and their new 64 bit ARM platform. Assuming the leaks are accurate, AMD seems to be doing a few things to address a number of problems with piledriver, and getting on a "modern" process will also help. We will see.

Intel is in a bit of a holding pattern, taking longer than expected to move to the next node (and why should they rush?); TSMC and the common platform, on the other hand, going balls out to get 20 nm up and running. AMD is limiting the use of macros in their future designs so hopefully they will be more portable, so if TSMC or the common platform get in a process bind AMD won't be as stuck (I think they are ditching SOI as well). Getting $60-$100 per XBone/PS4 should help as should a still competent design team, better fabrication process availability and a slightly less awful management team.

This is all speculation. Things may be dire, but there is reason for hope. It will be interesting to see in the near future if OEMs put jaguar in products that people actually want to buy.

As ridiculous as those new 220W TDP processors are, if single thread performance could beat the best Xeons out there they could sell a mints worth under the Opteron brand to certain industries. The fact they're not doing this puzzles me, and makes me wonder if these things aren't being as strictly validated as their other processors; or if this is just a PR game and they're not going to be able to harvest enough dies to meet the big OEM's demands.

EDIT: Based on the link Alereon posted, I guess the answer is that these processors won't beat the highest clocked Xeons in integer math in single threaded code. Maybe not even FP. That's really terrible.

If your board can do 125W processors, the AMD FX-4350 for $119.99 is probably a good option. Otherwise the AMD FX-6300 that is also $119.99 would work. Do make sure your board is compatible and update the BIOS first. Neither of these processors are great but they are an upgrade over what you have and the value could work out if you can keep using your motherboard. Otherwise definitely switch to Intel.

"Hating" implies that AMD hasn't been hit by the results of their own devastating failure to produce a competitive CPU. Remember how all the guys starting with "C" either got fired or walked, including the CTO of the graphics division? Remember how either nearly or over 100K workers got canned? Under new management they're totally shifting focus away from desktop CPUs? These things all really happened.

The company had to look in the mirror and acknowledge their failure, it's not some ol' bullshit for people in general to do the same.

I wish Bulldozer had Bulldozed. That would have been awesome. If anything, this is a thread full of people who entirely sympathize with AMD's position, but who also recognize the reality of their situation. Ain't a hater in sight.

HSA won't do much for single threaded performance as I understand it. It could potentially improve FP performance by offloading math to the graphics part of the APU. Some sort of "heterogeneous" architecture is the future, though depending on compilers has been a sucker's bet in the past. HSA is no EPIC, but the sinking of the Itanic is a cautionary note.

That wasn't a very good article to be honest, they only tested at settings that almost eliminate the CPU as a factor, and average framerates don't do a good job of showing the dips in framerate that are caused by the CPU. TechReport's reviews are a lot better for this because they actually compare the amount of time various CPUs spend below certain framerates, which shows pretty significant variability between CPUs.

Yes, 3D video games require a tremendous amount of floating point calculations, but almost universally this is off loaded to the GPU which is designed to do bulk parallel array/vector/matrix maths (e.g. calculating the color of each pixel on your screen, each frame).

While CPUs have gotten better at number crunching and x86 has added specialized instructions like SSEx and AVX to speed up vector operations, raw compute is still owned by GPUs. CPUs are more generalized processors designed to handle code that has branches (if x, then do y; else do z), and other dependencies that make up the bulk of consumer applications and things like game AI. There are, as you point out, some CPU dependent games like Skyrim or World of Warcraft. Intel rules for this stuff, but for a lot of games a CPU basically fetches poo poo from memory for the GPU to process; too slow and FPS will drop.

I also think that some GPUs have gotten better at branchy code to better handle certain functions, but only for the simplest of dependencies. Others ITT know much more about that than I. Eventually there will be no distinctions as CPU and GPU further converge.(Part of) The idea behind HSA is to send tasks best suited to either kind of processor without the programmer having to "vectorized" their code: making code parallel is quite challenging and for some things impossible.

Question. I'm debating between a core i3 and one of the new Richland APUs for my four family PC upgrades. My main driver is best all around performance for the 55-65w TDP range. I'll be keeping their discrete cards and am wondering if I do an APU and disable it in the BIOS does it technically drop the TDP lower? Like if I did a 100w one would it still use that much power with a disabled GPU or drop down much lower to be more competitive with an i3 under load?

Factory Factory
Mar 19, 2010

This is what
Arcane Velocity was like.
The way AMD's Turbo Core works, it would not change the maximum power of the chip, but it would change the average power. The GPU would pretty much never power up. The CPU would take a lot of the TDP headroom for its own turbo-ing, at least under stock configuration, and might potentially use the entire TDP under really heavy CPU load. At idle, though, the GPU would remain completely power-gated rather than on-but-not-doing-much, so that would reduce power consumption when the CPU wasn't doing much.

You could also manually undervolt/underclock the chip.

In an i3, there's no Turbo Boost, so you would just get lower power, yes.

Sanity check question: Why are you obsessing over the last handful of watts at a mid-level TDP? Get the Richland if your CPU uses are primarily multi-core, the i3 if they're primarily gaming, or get an i5-4570S if you need both, have the money, and are definitely wedded to that 65W TDP for some reason.

I can't strain the budget as high as an i5. Mainly I'm looking to try to collectively reduce heat/power usage, there are four PCs all in one spot in the house and it can get warmish and I don't want them too close to breaker popping. Also if I get them low enough I can plug them all into one (or two) big UPS, I don't need them to stay on long just not reboot for minor power blips, etc. Also I know jack poo poo about electricity so maybe I am over-thinking this.

I hate to say it, but one of the cornerstones of Intels dominance in the mobile space is that for consumer computing needs an Intel CPU will use significantly less power to do the same work. Go Intel, just get some i3s.

This is what
Arcane Velocity was like.
Lowering CPU TDP from 95W to 65W on three systems saves maybe 1.5A on the mains at 120V under full load, or about 10% of a typical US mains line capacity, and that's with REALLY lovely power supplies. With a decent PSU, it's more like 1.2A. A very high-performance desktop (6-core i7, 130W standard overclocked to 4.3 GHz, and a GeForce 770) takes about 3.3A (380W) from the wall. Your systems will take less unless you're using stupid old video cards and terrible power supplies. A toaster typically takes around 12A. Halve these amperages for 240V.

If you want to reduce heat, 120W less heat in the room... I mean, replace a 150W incandescent with a CFL and that's about the same difference. It's significant, but not very big. Increasing airflow through the room will pay off better.
