Currently what we know about AMD's upcoming Bulldozer. It seems AMD will rely on hardware based Multithreading vs. Intel's software implementation. It may cost AMD some die space, but it may also be there saving grace. IMO this new Bulldozer design is pure genius in terms of innovation. Now let’s see how it performs. There’s been a lot of thought put into this design as you can see by its complexity. Anyway reason for this thread is AMD is going to release much needed info on Bulldozer in late August 2010.

AMD to Disclose Details About Bulldozer Micro-Architecture in August.
http://www.xbitlabs.com/news/cpu/display/20100622123052_AMD_to...ugust.html

Bulldozer Design Breakdown
* Two tightly coupled x86 Processing Engines Per Module
(1 x Module = Dual-Core, 2 x Module(s) = Quad-Core, 4 x Module(s) = Octa-Core etc...)
* Advanced Multi-Threading Technology
* Two 128-bit FMAM Floating Point Units Per Module
(Can be combined into one 256-bit FPU per module)
* Shared L2 Cache among each module
* Shared L3 Cache among all cores
* Advanced Quad-Channel Memory Sub-System
UPDATE: DDR3-1600 Server/Workstation
(IMC - Integrated Memory Controller) UPDATE: 144-Bit
* Higher Memory Level Parallelism
* Two Integer Cores each w\ 4 pipelines Per Module
* DDR3-1866 - UPDATE: Dual-Channel DDR3-1866 (Desktop)
* 8MB of L3 Cache (2MB of L2 Cache per Module) UPDATE: via L2 Cache - 4-Core = 4MB, 6-Core = 6MB, 8-Core = 8MB
* 32nm SOI w/ High-K Metal Gate (HKMG)
* Advanced Vector Extensions (AVX)
(Supports 256-Bit FP Operations via AVX)
* Hyper Transport Technology 3.1
(3.20 GHz, 6.4 GT/s, 51.6 GB/s, 32-channel link)
* Socket AM3+ (Socket AM3 compatible)
* Min-Max Power Usage - 10-100 watts
* and so on...

Micro-Architecture Based on the information provided by AMD during its annual Analyst Day last November, the first Bulldozer chip code-named Zambezi (which belongs to Orochi family, according to the firm) will feature eight x86 processing engines with multi-threading technology, two 128-bit FMAC floating point units, shared L2 cache, shared L3 cache as well as an Advanced Quad-Channel Memory Sub-System (IMC - Integrated Memory Controller), higher memory level parallelism that's far superior to what today’s Phenom II houses. AMD also states that the new CPU will feature “Extensive New Power Management Innovations”. The new chips that belong to Bulldozer’s family will also support “Advanced Vector Extensions” (AVX) that supports 256-bit FP operations.

Sweet. I was waiting for something like this, AMD have really been progressing. Seriously though it's their prices that make them a win win. I still haven't seen an AMD cpu that beats a core i7 or an overclocked core i5, then again I stopped looking lol.

But if this new design performs like the Core i5,7 line then I'll bet they will sell quite well. I seriously hope they beat Intel at least this once, they need to do to intel what they're currently doing to Nvidia.

Indeed, they need a nice fast CPU like the old days.

I'm really hoping that "bulldozer" is this decades "sledge hammer", I'd like to see AMD start doing more at the high-end. Not that their current line up is bad (my Phenom II walks all over my C2Q) but I'd like to see more.

Remember Bulldozer is meant to smoke the crap out of the Nehalem design. Bulldozer is meant to compete w/ Sandybridge & behond. 8)

Well I hope it performs as they meant it. This reminds me when Intel launched their Core 2 Quad line and AMD was bragging that they weren't real Quad cores and just two dual cores glued together lol. Well those glued together dual cored whooped their chips for a long time and I believe some still do :P

Man, I hope bulldozer smokes Intel's stuff -- Intel's been p**sing me off. They have, like, billions of different sockets now... basically so that they can segregate the cheap CPU's from the expensive CPU's. That's pretty goddamned lame. Then they go and tell Nvidia that no one's allowed to make third-party chipsets for chips with integrated memory controllers, which are likely to be every CPU Intel makes from here on out.

Anti-competitive and anti-consumer practices draw out my ire, which is why I bought a Phenom II X6, and why I hope Bulldozer makes Paul Otellini have nightmares.

I love AMD. I've only owned AMD cpu's since I've started building and I have never had a complaint. The performance you get for the price is unbeatable. Seems with Intel you are only paying for the name. I hope this new CPU kicks ass... it looks like it will.

I wouldn't say that. Intel's CPU's are typically priced accordingly. They really do perform well. You can get a i5-750 for $189 and it's a deadly CPU. I like AMD a lot and when they have something that is the best thing you can buy for the price, I will buy it.

I have a few friends with Intel CPUs (my room mate has one as well) and I don't notice a bit of difference. If anything I think mine is a little zippier (especially with office/productivity apps). They payed about 2x the price too.

I believe A_Pickle is spot on, what's with Intel and all the different sockets? At least Bulldozer will be compatible with Socket AM3. Not sure about AM2+ though because they use DDR2 and I don't think Bulldozer's Quad-Channel is going to be both DDR3 & DDR2.

AM3 chips can go into an AM2+ mobo if I'm not mistaken, right?

And yes, I rather like AMD's stuff now. My computer's sweet! There's only one issue with it... it's otherwise fast, big, and silent. :)

most of the time with a BIOS update.

At first I thought Bulldozer would work on AM2+, but AM2+ mobo's are DDR2 and Bulldozer has a DDR3 IMC, so how would that work out? Unless Bulldozer will also have a DDR2 IMC also.

I was refering to the current generation Phenom II AM3 processors

No problem, but how about Bulldozer? It's based on Socket AM3v2. I guess we will have to wait and see, I mean Bulldozer is a completley new design which makes sense to buy a new mobo with a new chipset.

Did some quick research... I don't think Bulldozer has a DDR2 memory controller on it. Long story short, you're gonna need a DDR3 motherboard to pop in a Bulldozer chip.

No problem, I was already planning on picking up a new DDR3 gaming board based on the new chipset for Bulldozer. I wonder how well it's Quad-Channel DDR3 IMC is going to perform?
