| 1119705 | 2010-07-17 10:08:00 | Not sure but I want one! that and a quad core gfx card. Intel's 8-core CPUs will have 2.3 billion transistors 2.3b is a nice tidy number xD Sandia National Laboratories recently conducted simulations on the benefits and pitfalls of multi-cores. Their simulations show that moving from 2 cores to 4 cores shows a big increase in performance. However, moving from 4 cores to 8 cores barely shows any increase. And moving from 8 cores to 16 cores actually shows a decrease, down almost to the point of a 2-core system in terms of overall compute abilities. While these limitations were imposed primarily due to memory bandwidth limitations, we must realize that this 8-core behemoth (16-virtual core) machine will suffer from the same types of memory limitations on certain workloads. The only applications to see big benefits from 8-core implementations are those where high compute and low bandwidth are needed, and these are fairly rare. In such a case, it would be better to have several individual dual- or quad-core CPUs each connected to their own physical memory along with NUMA (Non-Uniform Memory Architecture) logic employed in the operating system. Judging by the above It doesn't seem like they will be released to the public market for a while until faster FSB's and S/HDD's are developed |

| 1119706 | 2010-07-17 10:19:00 | There are quad-core CPUs that have HyperThreading: while not really eight core they can do eight threads at once :) | pcuser42 (130) | ||
| 1119707 | 2010-07-17 11:20:00 | The 8 core CPU's are slated to do 16 threads | The Error Guy (14052) | ||
| 1119708 | 2010-07-17 11:47:00 | There are already 8 and 12 core AMD Opteron CPUs, but they are for servers. I think Intel may have 8-core server CPUs as well but I'm not sure, maybe someone can clarify? | forrest44 (754) | ||
| 1119709 | 2010-07-18 10:16:00 | 8 core cpu = waste of time. I cant think of any reason to buy one when they come out, maybe like 5 years after they do it could be useful |
