-- No Easter Eggs here --
AMD shows off their "Barcelona" quad-core chip designs

Source :

If you're not super excited by technical chip jargon like "advanced branch prediction" and "sideband stack optimizer," you might want to skip this one over, but for you chipheads out there, AMD has just unveiled the nitty gritty specs behind their forthcoming Barcelona quad-core processors. Built on a 65nm SOI process, the new chips will take the place of AMD's Opteron line, and will power workstations and servers sometime mid-2007 before the technology trickles down to consumer versions of the chips. AMD couldn't help but take a little pot-shot at Intel for their quad-core systems, which they claim are just two dual-core CPUs packed together, but we're pretty sure most consumers are going to be more concerned with performance, price and performance per watt than semantics. AMD hasn't provided any benchmarks yet, but we'll all be watching closely, since they're currently playing catchup to Intel on most of those fronts.

Wise Old Owl
AMD described its forthcoming quad-core processor, codenamed Barcelona, in a session at today's Microprocessor Forum. Details of the new microarchitecture on which the processor is based (codenamed K8L) have been known for some time now. Still, the event brought some new info, and here are some highlights that I've culled from some of the reporting on it.

AMD's new processor is a bona fide quad-core part, with all four cores integrated onto a single die and sharing a 2MB on-die L3. Each core has private 512KB L2 and a 64KB L1 caches. In contrast, Intel's quad-core Kentsfield part is a dual-chip module (DCM), where two Core 2 Duo dies are sandwiched together and put into the same package without sharing a cache.

K8L's floating-point and SSE units are now 128-bits wide, so AMD can now offer single-cycle throughput for 128-bit computation.

That's AMD's answer to Intel's Core 2 Duo Processor!!. It's coming soon!!

Wandering in time...
well that simple theory is of no good as intel core2duo beats pentium D processors by a large margin...even though both are dual cores...


Bewitched! it come the giant of the processor 128 Bits... 4 core... i expecting the 8 Core preocessor form AMD..

AMD Rules .... :p


LOL man no point investing on the best comp man.Now-a-days technology gets outdated in weeks.Dr.Moore's law of 18months is not holding good any longer!!!

well it seems that intel will still kick the **** out of AMD's with "Yorkfield"....
this processor battle is really getting on a new height...lets wait & see who comes out as the WINNERS.


Right off the assembly line

I know Intel quad core processor are just 2 core2duo placed side by side (the same mistake they did with Pentium D.) but still it would be tough for AMD to beat.

Because a single Core 2 extreme processor beats 2 dual core Opterons!!! Thats 2 Intel cores VS 4 AMD cores and still Intel wins!!

obviously u havent checked the everything the dual core opterons have won....the title is so misleading.....

ya I was reading a mail yesterday I received about AMD launchin the Barcelona core soon.Supposedly the C2D killer core is supposed to be 128bit.****,rite now the comp that I'am using to post here still uses a 32bit proc.Wow!!!
Similar thread:

plzz the barcelona is not a 128 bit processor but jus a 64 bit processor only...its jus the sse units that are 128bits wide and will give it higher integer processing power than the K8's...

intel will counter the barcelona with bloomsfield 45nm quad cores...

and well by the time a desktop version of the 65nm barcelona know by an code "altair" quadcore and "antares" dual core hits the market intel wud have produced 45nm "wolfdale" dual core and "yorksfield" quad core processors...

one other thing which will hit amd hard is the fact that "barcelona" is still a 3 issue core that means that it can do a max of only 3 Instructions per clock while even the core 2 duo can 4 this adv will be a huge boost for intel.....combined with macro fusion which will let 5 IPC under favourable conditions...

the 45nm wolfdale is supposed to be clocked at 3.5Ghz to 4.0Ghz while the amd 65nm antares will be clocked at 2.7-3.0Ghz that wud mean that even if the barcelona isa core 2 duo killer intel will be well ahead in terms of clock speed which miight jus negate the effects of better architecture...

the barcelona will probably better than yorkfield clock fo clock but intel has advantages in terms of processing technologies...i.e intel will have 45nm processors by the time amd jus starts getting 65nm....

what might really turn the tables in amd's favour is the strong 64 bit performance boost it shows over the core 2 duo's...core 2 duo's cant do macrofusion under 64 but due to a flaw in intels EMT64...that means amd barcelona/antares/altair can potentially wipe the floor with intel bloomfield/yorksfield/wolfdale with

i am an ardent amd fan...but i hate to say has really pulled off some thing amazing with their core 2 duo series...and most probably they will jus sit on their laurels and make mistake jus like amd did with their K8....

and when the amd K10 comes to life im pretty sure it will jus kill the intel Nehalem which will succeed conroe in 2H 2008

Sup' dude, Sup'
You guys are missing one point. For mainstream market, Intel's quad core is gonna come 6 months earlier than AMD 4x4. This can be a disaster for AMD as Intel will have very high chances to have dominance in this segment. Until AMD completely changes it's processor architecture, it cannot beat Intel.

FYI, what enduser want is performance, whether it is two dual cores side by side or one over the other :)

I am eagerly waiting for a killer processor arch. from AMD (like Intel's Conroe). Not Bacelona.

Obviously, you haven't checked the scores. Look again. The c2d beats the 2 Opterons in all the CPU tests.

well AMD's Quad Core is not gonna be 128 bit . 128 bit computing hasn't even hit servers yet .

BUT , it has hit consoles , my 6 year old Dremcast has a 128 bit RISC processor :D
