Orochi, octa-core Bulldozer in works

Written by Fuad Abazovic


GTC 2010: This is how it looks

AMD has dared to show a picture of Orochi, an eight-core 32nm Bulldozer-based server CPU. This will be the first Bulldozer to come and we expect to see it in 2011.

This is also the future high-end chip for AMD even though we are not sure why consumers would want to have eight cores on their desktops, but we do know that it will happen whether or not we want it or not.

Together with Llano, Orochi will be AMD’s first high-K metal gate 32nm chip and they are both expected in 2011. We believe that Bulldozer has already been taped out as in the CPU work it takes roughly a year from the first tape out to final product.

Since we expect Bulldozer Orochi to ship in the second half of 2011, the samples should be ready as we speak. At least it was mentioned today at the Global Technology conference here in Santa Clara, California, ironically just a mile away from Nvidia and Intel headquarters.

Once I get one of these, and I AM going to get one, I'm done upgrading. Period. Till that processor is stone dead. Because it's not like games or operating systems are catching up to that kind of hardware anytime soon.

The Orchi ist 4 or more Core but amd says it is an 8 Core processor. The DIE ist very asymetric ther are 4 diferent modules on that die.

nvm

So it's 4 core not 8 core... with the right clocks, it should be a winner.

if most data is integer and it has 8 integer processors, then it`s more of an 8-core processor than 4-core. So, It`s 8 cores.

Fuad, Bulldozer taped out some time in q2. AMD told us that in their last financial conference call.
Others, this is Desktop Bulldozer (Orochi) 8 core die shot. only thing is, it is very photoshoped to not give away some stuff to competition. Here is some info from the horses mouth: http://www.amdzone.com/phpbb3/viewtopic.php?p=188312#p188312

Also if most floating point code is 64 bit floats, the FP unit is known to be capable of dual issue, so it could be viewed as eight FP cores.

Some diagrams of the Bulldozer core show the FP unit as four 32 bit. Thus, it may be capable of four simultaneous single precision FP ops.

If this last is actually the case, and it's scheduler is done very well, then Bulldozer core could be very good indeed at audio/video transcoding and also at games.

ie: dual issue of a pair of 64 bit float ops.

Quoting hoohoo:

each module has 256bit FP unit, which can be split to 2 128bit pipes or 4 64bit pipes. so we have 4 modules(Orochi) , thus we have 16 64bit pipes or 8 128 bit pipes or 4 256bit FP fatties for some AVX optimised goodness.

Pointless screen-shot... that's an edited and partially blurred image, missing L3, asymmetrical cores, so the actual die will look different. (XTS, JF-AMD)
