Advanced Micro Devices at present is not able to compete in terms of pure performance against Intel Corp.’s Core i7-series “Sandy Bridge” microprocessors, according to benchmark results, but with its next-generation Bulldozer-based chips the company fully aims to fight.

With its FX-series AMD Zambezi desktop processors the Sunnyvale, California-based company plans to fully compete against Intel Core i-family of high-performance central processing units. A document from AMD seen by X-bit labs claims that AMD FX-series central processing unit (CPUs) powered by the Bulldozer micro-architecture will be fully able to rival Core i7 2600-series chips. 

Among the advantages that are mentioned by the AMD documents that X-bit labs has happened to see are “more overclocked cores”, “more cores dual graphics, OpenCL and GPU” compute and others. By the end of the year the firm expects over 10% of its desktop products to be based on the Bulldozer micro-architecture and be in the AM3+ form-factor.

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.

If the 8-core Bulldozer can't be faster than the 4-core + HT i7-2600, it will be disappointing.

What if AMD wants to provide more for the same money, hence regaining marketshare?

Fake chart full of bullshit and obviously photoshopped.

Let's hope it's fake then, since AMD needs more performance than simply matching the i7-2600K.

In fact, I think it's worse than that. The Octo-Core FX isn't even competing with the i7-2600K in terms of performance; It's competing in terms of superior core count.

Thuban vs Nehalem/Lynnfield, anyone?

You mean superior Integer core count they both have the same amount of floating point cores so... Superior core count is in the eyes of the beholder if we put it up against a 6 core intel i7 then Bulldozer would have more Integer cores physically while less virtually although it would at the same time have less floating point cores physically and virtually so there really isn't a good way comparing these chips against Intel core wise.

Either way this chart is just matching the systems price wise (remember SYSTEMS) doesn't say much about the speed of these processors.

If amd would cost more money then it's processor performance would exceed intel's processor a million times!!!!!!!!!! Wake up dude dont be a puppet for intel...

think about this if amd would cost more money than an intel's processor then it will perform a thousand times better than intel's processor!!!!!! so dont be a puppet for intel...

Yep and by then Ivy Bridge will be out. so AMD will still be a step behind in performance, but if they can keep the price compeititve then it may equal out.

Ivy Bridge is only a die shrink. Obviously next gen Bulldozer would see the same .

$ 700 AMD FX For Fight With i7 2600 $ 280 ???

and A8 3550 Quad core $ 600 For Fight with i3 $ 130???

Ow.... i think its bad idea...

So buldozer 8 core just can fight with 4 core intel, and 6 core intel (and 8 core intel) Still Number 1....

It is sort of an 8 core processor (Bulldozer is 8int 4float cores for an 8 core), but you need to read the chart $700 = SYSTEM PRICE meaning an entire computer not just the processor. So an A8 3550 would cost you $600 for an entire computer that should match up against a similar $600 i3 based system. These are prices for your average consumer not system builders.

Ow, so the price Cpu is same with i7 2600?

If yes maybe AMD worthed for price, but 8 core fight with 4 core is shame to buldozer i think.

Except 8 core buldozer can fight with 6 core/8 core intel that what i say good news..

And for intel, when to produce cpu 6-8 core for $ 300-400?

Just remember the architecture of Bulldozer it may have 8 cores but that is made up of 8 integer cores and 4 Floating cores (4 Modules) so it is hard to say what is really fair considering a 4core i7 has 8 virtual cores due to the way it works internally so another way to look at it
Integer cores AMD 8/ Intel 4(8 Virtual)
Float cores AMD 4(8 virtual)/ Intel 4(8 virtual).

So I am not really sure how fair a 6 or 8 core Intel chip would be against an 8 Core Bulldozer chip, but I am sure AMD could provide us with a 10 or 12 core bulldozer chip in the future.

they porb have alreary have like a 12 core cpu in standing, why put in the market to benefit like maybe 2-3 application... They are waiting for amd to release their 8 core and laugh at them because they can't beat their 4 core product then release their new 8 core cpu and kill the competition over and over. Amd did the exploit to beat intel back in the XP line day. I doubt they will do it again.

Even if the Chart is fake the idiots who say that an 8 core Bulldozer will be $800 are stupid...if the bothered to look at whats above the prices they would see $800 is the total System cost! Fanboys...

if they manage to have good perfromance, low idle power, good price/performance then this is what matters and they have a winner.

also remember that the 8 core buldozer is not actually 8 cores. it's four modules and each module is more than one core and less than 2. 4 core sandy has 4 cores that are seen as 8 but almost no hardware is duplicated. one could say 4 core sandy has 4 fat cores, and 8 core buldozer has 8 slimmer cores. so not exactly apples to apples comparison.

i do think that bulldozer has something on sandy. we shall see.

wrong Bulldozer has 8 REAL Int-Cores (less float core's though) They may be smaller than Sandys on silicon but they are still real.

what you are getting at is the 180% Bandwidth number when 2 bulldozer Int cores are compared to a mystical non existent Bulldozer Dual Core (which is similar in design to Intel's processors)

that is also the reason why these things are marketed as Octocores why else would they sell them as Octocores when they aren't really ?

also didnt JF-AMD say that a Octocore Bulldozer could be compared to a non-module design Bulldozer Hexacore.

also Sandy has only 4 Cores ht is nothing more than a few extra registers...
