saw a presentation of Nehalem's performance in Cinebench at the Intel Developer Forum. Intel had three systems: one with a Core i7 Nehalem chip with unknown clockspeed, a Core 2 Extreme QX6850 system and another one with the old Pentium EE 955. Here are the results:
Three Intel CPUs calculate identical videos: a Nehalem/Bloomfield, a Core 2 Extreme QX6850 (3.0 GHz) and an elderly Pentium EE 955 (3.46 GHz). The clock speed of the Nehalem system is kept secret, but because talk is about "comparable frequencies” we suppose it is the 3.2 GHz model.
The Nehalem rendered the video in 1:06 minutes, the Kentsfield in 1:45 minutes and it took the Presler 7:28 minutes to do the job. Of course the video software benefits from multiple cores and Hyper-Threading. An SSE4.2 optimization is not included, yet.
