Phenom II 6 GHz+ OVERCLOCK

[qurious63ss]

The problem with relying on multithreading is that AMD can retaliate easily with 6 cores.

Yes, Intel will probably do the same (6 on 32nm), with AMD having 2 Shanghai/Istanbul (8/12c) dies on one chip as a strikeback.


So server/workstation side, it's rather futile. There is not going to be a Conroe like 2 year lead. It's 6 months - 1 year at best. Sandy and Bulldozer should shake things up a little, but they're both emphasizing on special instructions like AVX/SSE, I wonder how much more core improvements they can have.


Oh, and about the benchmarks. Remember- this is the "oh-so" inferior and narrow K10 architecture that only issues 3 instructions per clock, unlike Core 2. It getting even/beating the C2 is something quite remarkable.

6 cores on 45nm will make the die 50% larger so I don't see this as a wise choice for the desktop.

6 cores on 45nm will make the die 50% larger so I don't see this as a wide choice for the desktop.

Acually one Shanghai/Deneb core is 15.3mm2.The 6 core part(as shown by Hans De Vries) would be a sub 300mm2 chip.Nehalem single core size(one core on the monolithic die) takes up ~24.4mm2 or 1.6x more than in Shanghai(SMT among other things).

"It's probably not a bad idea for AMD to take advantage of their relatively
small core size. At 45nm it can cram two cores (with 256 kB L1 total) into
30mm2. A single Nehalem core with 256 kB L2 also occupies ~30 mm2.

So in terms of IPC/mm2 you get two cores against one core with 2 threads."
