AMD is actually working pretty closely with ARM. While I don't think they'll make ARM CPUs, there's been talk that they'll produce a licensable GPU block for ARM CPUs, much like PowerVR.

Imageon was a media processor SoC, which is exactly the business they don't want to be in right now. Here's an article from SemiAccurate which includes a lot of links to articles about ARM's participation in the AMD Fusion Developer's Summit last summer, which includes ARM pushing heterogenous computing. There's nothing concrete here, but designing an embedded GPU core could be a way for AMD to get back in the mobile game without requiring them to have a lot of expertise in the SoC space, especially if their GPU products offered a compelling OpenCL compute performance advantage over competitors. There may be room here, as nVidia is still not offering unified shader architecture products and PowerVR only makes GPUs that use Tile-Based Rendering, which is good for efficiency but imposes a low performance ceiling. No one really seems to be adopting the ARM Mali either, though this could all shake up when we finally see the next generation of mobile GPUs.

Bulldozer Opterons were launched today, we're waiting for reviews to get written. Basically, AMD will deliver a 16-core Interlagos Opteron at the same clockspeed and TDP that you would have gotten a 12-core Magny-Cours Opteron at. A guy on the Real World Tech forums ran some numbers, the new Opterons are about 7-15% slower per-core at the same TDP, but 5-29% faster on a per-socket basis at the same TDP. A welcome improvement compared to their old Opterons, but not really enough to start to catch with Xeons, especially since Xeons already had the per-core performance crown.

The 7800-series (and lower chips presumably) slipped from September 2011 to "some time before the end of the year," with volume in early 2012 (we might not see any at all until next year). The 7900-series will probably be a bit after that.

I'm no AMD fanboy (OP of the Sandy Bridge thread checking in), but that analysis seems really bad. Frankly, Ars Technica is a lifestyle blog, they gave up tech years ago and this article shows they don't have the expertise to draw meaningful conclusions. They're analyzing Bulldozer in terms of per-core, per-clock performance, when it needs to be analyzed in terms of per-socket performance. They're looking at benchmarks from bizarrely configured multi-million dollar server installations, when as Anandtech points out the actual real servers that people would buy give AMD a HUGE price advantage, especially when large amounts of RAM are involved. They also called out Bulldozer for poor power efficiency in virtualized applications, when Anandtech showed that this was an ESX issue. It's not even anything complicated like thread scheduling, just that enhanced C-states are disabled by default. This is something that's pretty easily fixable, either yourself or through an ESX update.

Really, Bulldozer for servers isn't the hit out of the park that people were hoping for, but it IS a tangible incremental improvement over Magny-Cours at the applications that people buy AMD processors for, which are virtualization farms and other situations where you want to cram as many cores and/or RAM into a given power/money/space budget as possible, and don't really care about per-thread performance. It doesn't really change the landscape much, except for the addition of encryption/decryption acceleration.

AMD has canceled their Wichita and Krishna APUs, the successors to Brazos, because TSMC Global Foundries is unable to get the 28nm process working within a reasonable timeframe. Instead, they'll refresh Brazos on 40nm with slightly improved clockspeeds and turbo. They're renaming the integrated graphics to the Radeon HD 7300-series, but it's still VLIW5 so I doubt there's any meaningful changes. The real changes are in the new chipset, which will include SATA600 (2 ports) and USB 3.0 (2 ports).

On the plus side (well, minus side for us) Intel's Cedar Trail Atoms are complete poo poo, they have an improved on-die GPU with DirectX 10.1 support, but Intel decided to give up on trying to write drivers. They're releasing DirectX 9 only drivers for Windows 7 32-bit only, there will be no 64-bit support or exposure of the DX10.1 featureset until at least Windows 8. It'll be 2013 and the Silvermont architecture before Intel has anything to answer Brazos with.

28nm has been hard for everyone, and they were having trouble getting 32nm going for Llano so AMD should have saw this coming. That fact gives me pause about the idea that they would go with them for Wichita and Krishna, especially since TSMC built Brazos. It just seems weird to switch like that generation wise.

Y'know, one thing that's been bugging my uninformed-about-chip-fab self about Bulldozer has been AMD's recommended overclocking voltages.

In [H]'s Bulldozer review, it quoted AMD as saying to overclock by setting a Vcore from 1.4 to 1.55 V.

It took a little re-evaluation, but Intel recommended a top voltage of 1.38 V for their 32nm processors.

Is AMD's process different, or are overclocked Bulldozer chips going to burn out faster than a fart in a frat house?

Power consumption makes the question of how good they are at overclocking more complex. For starters, the FX 8150 BE (3.6GHz stock) draws about 240W stock, compared to 130ish for the 2600K and 2500K at their 3.4GHz and 3.3GHz stock speeds. The FX 8150 goes over 400W once you get them to 4.5GHz+, compared to Sandy Bridge which are hanging out around 200W at 4.6GHz.

That's when really loaded down, obviously, but still, the power consumption comparison and clock for clock performance deficit means why would anyone build an FX chip system if they aren't an AMD supporter regardless?

Considering that Interlagos is more power hungry, likely more expensive to make (due to the massive die size of each Orochi die), and has the advantage of being a process node ahead of Magny Cours, the fact that it's only sometimes faster is really damning.

Contrast this with Intel's ability to get ~20% performance increases from generation to generation without a process shrink and that makes AMD's failure even more stark. If having a product that's late, slow, hot and costly to make while your competition is moving forward almost without fault isn't a catastrophic design failure then I'm not sure what is.

Forget anything from Intel or even the PhII X6s, that thing has trouble beating a ~3 year old X4 955BE, both stock or when overclocked. It makes even the lowly $130 price tag look overpriced.

The marketing team that decided to pretend their modules were cores really, really, really screwed up. It makes comparisons look godawful. They should have gone with conventional and comparable marketing to other current and in-production hardware. Nothing to be ashamed of for selling a 4-core processor with nifty hardware-based dual threading per core. They could have really capitalized on how it's not like Hyperthreading where it's barely hardware at all, just presenting 4 real and 4 logical, no, this is real, hardware dual-thread per core!

But instead they went with the deeply misleading modules/cores approach, and so people look at what AMD are calling 4-core processors and expect them to perform competitively with other 4-core processors. Then they don't, because they're actually 2-core processors with a nifty hardware element to their dual threading but it's not the same thing as full blown cores... Which makes them look really awful by comparison.

Even the ad speech about AMD bringing the first 8-core desktop processors to market is baffling and stupid since performance comparisons show the only thing remotely 8-core about the higher end FX-line is their power consumption, which does start to look like octo-core setups.

Horrible idea, way oversold the concept, could have been done with so much more finesse. Aaarrgh AMD you're killing me here.

It's perfectly legitimate to call a 4-module Bulldozer processor an 8-core processor. There's nothing fundamentally wrong with this approach, it's just that Bulldozer had so much cache that it ran up against the limits of how big you can make a CPU, thus preventing AMD's designers from spending the transistors necessary to actually perform well in the real world. Anandtech's Bulldozer article goes into some detail about the compromises AMD made both for die size and in the pursuit of clock speed, unfortunately the latter couldn't pay off at all because Global Foundries was unable to deliver to expectations on their 32nm process. On the plus side, this does mean that when AMD refreshes Bulldozer for the desktop without the L3 cache (and presumably on a more mature 32nm process), it could see meaningful improvements.

They've landed a number of supercomputer deals for Bulldozer-based Opterons, each of those is a not-insignificant number of dies (thousands of processors, two dies per processor) sold at substantially above consumer price levels. The only thing you're going to see branded as an FX-series processor are either defective dies that couldn't be sold as Opterons or excess supply above and beyond what's needed for their server business. Since yields are still very low it makes sense there wouldn't be much available for consumers.

Thing is, quad-core CPUs are by no means universal: link. About as many Steam users are still using dual-core CPUs as are using quad-cores. Folks with 8-core BD CPUs will be long, long, long in waiting for their market segment to have enough representation for 4 vs. 8 threads to be worth a programmer's time.

Its still progress IMO. You'll always have these guys leading the pack. If having one 8+ core zealot means 3 dual core buddies upgrade to quad or above, then I think they are doing everyone a service.
