The GPU Megathread is here, this thread is about CPUs, APUs, and AMD platforms in general. Don't loving buy an AMD FX-series CPU. Breaking news: Bulldozer delayed until late July due to disappointing performance AnandTech posted:Just above Llano we will have the long awaited Bulldozer CPU. AMD originally wanted to launch Bulldozer at Computex but performance issues with its B0 and B1 stepping chips pushed back the launch. Now we're looking at a late July launch with B2 silicon, but performance today is a big unknown. Apparently the performance of B1 stepping silicon doesn't look too good. Also from that article, Info on the 9-series chipset: AnandTech posted:To differentiate AM3+ from AM3 motherboards AMD is releasing a new chipset: the 9-series. Functionally the 9-series chipset is no different from the 8-series that it replaces; it'll simply be used on AM3+ boards exclusively. What The gently caress is Bulldozer? Bulldozer is the next-generation micro-architecture and processor design developed from AMD. Bulldozer will be the first major redesign of AMD’s processor architecture since 2003, when they launched their K8 (Athlon 64/Opteron) processors.   Technical poo poo: Bulldozer core "modules" will consist of two 4-pipeline cores that share a Float Point Scheduler and two 128-bit FMACs. Since a very small amount (outside of HPC) is FP calculations in today's code, the shared FP scheduler allows some significant power savings. The shared dual 128-bit FMACs can be used by each core or doubled up and used as a 256-bit FMAC. For this to be beneficial however, it will have to be specifically coded for. These cores also share an L2 cache. These modules can be arranged and connected via HyperTransport Bus facilities build multi-core processors. The 6000 series server processors will have 12 to 16 cores, or 6 to 8 modules. The 4000 series will have 4 to 8 cores. Server side chipset will be identical to what is currently on the market and G34 (6000 series) and C32 (4000 series) sockets will accept these server processors. These processors will work inside the exact same thermal envelopes as the previous processors, but will of course have up to double the cores. Block diagram:  "Significant enhancements" have been made to the memory controller that will represent a substantial increase in memory throughput, but that is all that would be said on the matter. It was interesting to hear AMD compare its Bulldozer module to current Intel HyperThreading architecture and you will see the comparison made on the slides below. AMD seems to be of the mind, "Why do we need something akin to HyperThreading when we can add an additional core to our module for about a 5% increase in die size?" AMD kept with the 2-core module to HyperThreading comparison throughout the talk. More low power states and more advanced and granular clock gating will also be part of Bulldozer and upcoming Northbridge parts for the desktop. Expect to see two channels of DDR3 memory per module as well. As well a new modes of AMD's TurboCore technology that "overclocks" the processors. Just to reiterate: Each Bulldozer die will be made up of multiple modules. Each module has 2 integer cores and a shared FPU.
Don't get hung up on modules. They only exist to the designers and in powerpoint slides. They will not be visible to the system or to the software. The OS cannot see the module, it only sees integer cores. New Socket Time! Bulldozer uses the AM3+ socket for the desktop, and Sockets G34 (LGA1974) and C32 (LGA1207) will be used in serverland. AM3 boards will not take AM3+ CPUs AM3+ boards will take AM3 CPUs Let me reiterate that for you, just so we're absolutely positively unequivocally clear on this: AM3 board + AM3+ CPU? NO AM3+ board with AM3 CPU? YES The advantages of AM3+ are:
Motherboards So Far Announced:
Info on the 9-series chipset: AnandTech posted:To differentiate AM3+ from AM3 motherboards AMD is releasing a new chipset: the 9-series. Functionally the 9-series chipset is no different from the 8-series that it replaces; it'll simply be used on AM3+ boards exclusively. Known BD models:
Q/A Time: Q: I'm trying to decide if I want to get a new motherboard and use my current processor until Bulldozer comes out or if I should wait and get the whole shebang when it drops? A: It is a great idea to spread out your spending, if you can. Get something from this list, it will be AM3+ compatible with a BIOS update.

adorai posted:Not bulldozer, but question relating to the new poo poo from AMD. Per clock, can I expect similar performance between an ontario/zacate/llano platform as I can get from PhenomII/AthlonII? I am considering replacing my fileserver, which is currently a 45W AM2 Athlon x2 1.9GHz. If I can replace this with an APU that consumes only 18W, and not have to worry about performance, it's worth it to me (my office has terrible air flow and it gets warm in there). If it goes well I might even replace my VMware server as well (Athlon X2 2.5GHz) since it rarely caps out. That is true.

New infamashun tiem! BD's FX line has a real release date! June 20th is the proclamation from AMD. Xbitlabs posted:AMD plans to release four eight-core AMD FX8000-series chips, two six-core AMD FX6000-series microprocessors and two quad-core AMD FX4000-series central processing units (CPUs) this year; four chips are to be launched in Q2 2011, another four processors will be introduced in Q4 2011.

madprocess posted:I'm sorry but I must inform you that if your son has requested a new "processor" from a company called "AMD", this is genuine cause for alarm. AMD is a third-world based company who make inferior, "knock-off" copies of American processor chips. They use child labor extensively in their third world sweatshops, and they deliberately disable the security features that American processor makers, such as Intel, use to prevent hacking. AMD chips are never sold in stores, and you will most likely be told that you have to order them from internet sites. Do not buy this chip! This is one request that you must refuse your son, if you are to have any hope of raising him well. Is this a reference to something? If so, do tell.

Alereon posted:The 28nm successor to the AMD Ontario and Zacate low-power x86 processors, the Wichita series, has taped out at AMD for production at TSMC. "Taping out" means the chip design has been completed and sent for initial test manufacturing, after which they make any further necessary changes. About two weeks ago we learned that the AMD Radeon HD 7000-series taped out about six weeks prior, indicating that both products may be on track for a launch potentially as early as Q3. I'd expect the new C- and E-series processors to have VLIW4-based Radeon HD 7300 graphics or something to that effect, I'm thinking it will have 64 shaders (one VLIW4 SIMD block), but they could double this if they don't scale clockspeeds instead. Given how awesome the x120e and friends are, I can't wait for this. :popcorn: Sinestro fucked around with this message at 19:42 on Apr 13, 2011 |

Space Gopher posted:The rumor mills are saying that Zacate's supply is seriously constrained, and that prices should fall naturally once AMD ramps up production to fulfill demand. Given that you can buy a complete 15.6" laptop with an E-350 for under $350, I don't think that the price of the chip itself is what's driving prices on stuff like Zacate mITX and desktop boards so high. I hope they drop soon. I need a new NAS, and I want as much money for drives and a RAID card as possible.

Alereon posted:AMD CPUs are currently manufactured at Global Foundaries on the 45nm Silicon-On-Insulator process, transitioning to 32nm. AMD GPUs are currently manufactured at TSMC on a bulk-silicon 40nm process, transitioning to 28nm. You can't make AMD CPUs at TSMC because they're designed for GF's Silicon-On-Insulator tech, and vice versa. GPUs have historically been made at "half-node" processes, which are sort of like half-steps beteween process shrinks. For example, while CPUs shrank from 90nm to 65nm to 45nm, GPUs went from 80nm to 55nm to 40nm. Wow, that makes no sense at all. It is both SOI, why is it different? (Took one class on IC design in school, never used or thought about it since)

Alereon posted:Global Foundries is using SOI, TSMC (and nearly everybody else) isn't, sorry if I wasn't being clear. That means there's pretty substantial differences in the processes and the resulting chips. Those significant differences are why it made sense for AMD to fab their Zacate APUs at TSMC, since they were reusing their graphics cores and could design new CPU cores for TSMC's bulk CMOS process. Ah, that makes much more sense. I thought you were saying that TSMC had SOI as well and I was all  .

Cuntpunch posted:I will admit to finally going back to Intel after nearly a decade with AMD. I respect the company but I just couldn't find it in myself to wait an indefinite amount of time to be able to upgrade to the next-gen tech. However, I would be terribly sad to see AMD start to falter, but as far as I can tell they've put themselves between a rock and a hard place with Bulldozer. Even if they can manage spectacular performance(and price ratios as is their way) compared to Sandy Bridge, it seems like they'll have taken center stage just in time for Ivy Bridge to come around. I am hoping for a neck-and-neck, if not a winner.
