Early Version of Intel's Nehalem Benchmarked, Much Faster than Penryn
Despite only having access to early chips and early motherboards, Anandtech was impressed:
First keep in mind that these performance numbers are early, and they were run on a partly crippled, very early platform. With that preface, the fact that Nehalem is still able to post these 20 - 50% performance gains says only one thing about Intel's tick-tock cadence: they did it.Anandtech had access to a 2.66GHz Nehalem processor which they pitted against a 2.66GHz Penryn processor. Performance improvements ranged from 20-50% faster for the Nehalem chip. h.264 video encoding was tested and saw a 44% speed boost on Nehalem vs Penryn on the equally clocked processors. They claim that the 2.66GHz Nehalem outpaces the current top-of-the-line 3.2GHz Penryn. The speed increase comes at a cost of only a 10% increase in total system power consumption.
Apple will certainly adopt the Nehalem processors after they become available. While the first server-grade Nehalem processors are expected in Q4 of 2008, desktop and laptop models won't be available until sometime in 2009.
