Engineering Samples of AMD's Next-Generation Desktop Chips Due Next Month

Advanced Micro Devices will start production of its code-named Zambezi central processing unit (CPU) based on the highly-anticipated Bulldozer micro-architecture in April, 2011. Initially AMD plans to release 8-core microprocessors for desktops, but later in the second quarter of next year the firm intends to launch six-core and quad-core chips based on Bulldozer micro-architecture.

The first engineering samples of Zambezi chips that will be available for AMD's partners for testing will be released already in December, 2010, about a month from now, sources familiar with AMD plans told X-bit labs. Production candidates should be ready by February and the initial production of the company's first desktop microprocessors powered by the long-awaited Bulldozer micro-architecture is scheduled to start in April next year. Probably, the launch of the chip will occur around the same timeframe.

The first Zambezi microprocessors to be launched are expected to be eight-core products with 95W and 125W thermal design power as well as 8MB L3 cache. Later in the second quarter of 2011 AMD, according to sources with knowledge of the company's roadmap, will release six-core chips with 8MB L3 cache and four-core products with 4MB cache. All of the processors will feature TurboCore 2.0 technology, dual-channel DDR3 memory controller with up to 1866MHz memory support and will be compatible with AM3+ mainboards.

Eight-core Zambezi/Orochi features four dual-core Bulldozer modules, each of which is believed to have 2MB of shared level-two cache, that will share 8MB L3 cache. In total, the whole chip will pack in whopping 16MB of SRAM, a 77% increase from the current six-core microprocessors that have 9MB of cache in total.

It is noteworthy that AMD's Zambezi microprocessors made using 32nm silicon-on-insulator process technology by Globalfoundries will be available earlier than the company's code-named Llano chips that combine current-generation x86 cores with current-generation DirectX 11 graphics engine on the same piece of silicon.

AMD Orochi design is the company's next-generation processor for high-end desktop (Zambezi) and server (Valencia) markets. The chip will feature eight processing engines, but since it is based on Bulldozer micro-architecture, those cores will be packed into four modules. Every module which will have two independent integer cores (that will share fetch, decode and L2 functionality) with dedicated schedulers, one "Flex FP" floating point unit with two 128-bit FMAC pipes with one FP scheduler. The chip will have shared L3 cache, new dual-channel DDR3 memory controller and will use HyperTransport 3.1 bus. The Zambezi chips will use new AM3+ form-factor and will require brand new platforms.

The Sunnyvale, California-based chip designer plans to introduce AMD 900-series chipsets compatible with Zambezi processors in Q2 2011. The Bulldozer processors, Radeon HD 6000 "Northern Islands" discrete graphics cards and AMD 900-series core-logic sets will power AMD's next-generation enthusiast-class platform code-named Scorpius.

AMD did not comment on the news-story.

I hope the 8 cores perform well.. if they're anything like the current 6 cores then it's just going to be so underwhelming.

darnn.. was hoping for an earlier release date ....nooooooooooooo! :P
 
That's what's holding me back from getting an am3 rig. I'v heard it's going to be a new platform: am3+ (with no backwards compatibility??)
 
I am pretty sure they are on a new socket hence why i havn't bought an am3 to tide me over. Price wise i cannot see these being hugely expensive as intel already has a competitor cpu so i think amd will stick with the bang for buck approach they have adopted in recent years.
 
AMD Orochi sounds good but no mention of its release ?

Proberly will arrive in fall 2011 to combat the new Core i7-2....

Bet AMD will need an 8 core cpu to take on the mighty Core i7-2 come early 2011 anyhow.
 
Well although i am waiting for both to be released as i have said before i have a hankering to go amd so i am hoping they can get them out quick and be good cpu's.
 
Even if it's not much faster than current phenoms I think it will still be a very good buy if it comes at like 200 - 250 quid. I think it will be as good buy as a q6600 back in the day - it will last very long before it starts struggling and should gradually become better and better over time as more software will get better optimized for multi core setups.
 
Going by the latest news about Bulldozer I have seen posted on the forum, it seems AMD is taking another approach rather than pure performance part with this chip
and is not made to kill Intel`s chips on performance that everyone thought it would be, so it seems Intel will probably be performance king this year coming as well.

What are you talking about, the current rumour mill is that it might not quite match Sandybridge in clock for clock, per core performance per clock, but could be released and overclock to higher clock speeds.

LIkewise its a VASTLY improved IPC speed, its vastly improved performance over phenom per core/per clock/overall and should be the current i7's in clock for clock performance quite easily.

They've gone for a design whereby, hopefully an 8 core Bulldozer should be significantly smaller than an 8 core i7, as with the dual interger cores per fpu design its apparently only added on around 5% die space to add a second core to each module. Meaning price/production wise on the same process(which they won't be to start with but within a couple years glofo should be right on top of Intel when it comes to process release times) it should hold a massive die size advantage.

Its got what should be massively improved interger performance, a lot more FPU performance, fantastic FPU performance when AVX instructions become standard.

Anyway because of the die size increase from current 4 core, to future 8 core designs, they'll basically slip right in at likely marginally higher than current pricing, but the new 4 core versions should be cheaper than current 4 cores, because size wise they'll be closer to dual core than quad core size.

I've been saying for the past year, if you've got any current quad core, unless you do high end constant cpu work for your job where time = money, then theres no significant upgrade to be had for 99% of home use, next year, Sandybridge and Bulldozer are going to be huge advancements.

April production and similar release sounds like utter bull though, CPU's don't take a matter of minutes to pump through a processing line, they get etched, and this and that, for WEEKS, not hours or days.

In GPU terms AMD/Nvidia gpu's take SIX WEEKS from first stage of production to out the other end. I'd say 6 weeks at least really, often more and CPU's take a similar amount of time. Theres so many steps in the process, it takes a very long time.

So if production started on April 1st you wouldn't really expect to have chips finished before mid may/june, and as with most things you tend to wait several weeks so you can launch with a few weeks production ready at least.

IE production in April and a release around the same time, unless a paper launch, is highly unlikely. Also AMD have released server parts before desktop for a long time now, in general, and I wouldn't be surprised if that continued.

I'm fairly sure server parts samples have been "around" for a few months and real production of server versions of Bulldozer could start very soon, potentially even have started already. Bulldozers a MASSIVE change, and on a new process, and a new process for the first time with GloFo split off from AMD, and while GloFo are spending upwards of 20billion expanding, upgrading and building fabs from scratch so they are a tad busy aswell.

Realistically Bulldozer could launch anytime from March to September depending on when they start production.

Yep Drunken is spot on from what i have read also it may or may not be comparable to performance sandybridge but is going to be very comparable or better then current i7 chips. There are other improvements coming as well and rather then just concentrate on the cpu the whole package has to be considered and i look forward to some real world testing.
