Some tests I found in web.
| Because 3D mark CPU bench takes advantage of all 8 threads on an i7. You've only got 4 cores and 4 threads. Your physics score is: 6823 i5-3570K @stock clocks His Physics score is: 8535 i7-920 @4ghz (stock of 2.8ghz) That's why he scores higher than you. |
8-core does make difference in score.
The FX 8350 Stock and 3870K APU - OC to 3.6 Ghz are more on pair in game performance per core in @disolitude tests.
I have to add that too with the PS4/Nextbox comming the games will start to be more optimized to 8-cores than they are today... devs will make the games run better in 8-cores CPUs (except the PC exclusives).
So PC will have a grest advantage in games in two or three years in terms of CPU with 8-cores.
