For those who haven’t heard the news or read our forum threads, Nvidia has announced its latest and highest performance DirectX 10 mobile GPU, the GeForce 8700M GT.
Packed with the same 32 stream processors (unified shader engines) as the previous generation 8600M GT, the new 8700M GT boosts the core clock from 475MHz to 625MHz. The shader clock has also been increased from 950MHz to 1,250MHz and the memory clock has increased by 100MHz (from 700MHz to 800MHz). The memory bandwidth is up from 22.4GB/s to 25.6GB/s and the texture fill rate provides an impressive 10 billion instructions per second (up from 7.6 billion instructions per second in the 8600M GT).

Nvidia is also touting the fact that the new 8700M GT can accelerate the entire H.264 video process, making it easy to play Blu-Ray, HD DVD, and other 1080p-native movies on a notebook without siphoning away CPU and memory resources. However, the same HD video processing performance claims can be made for the entire GeForce 8M series notebook GPU lineup.
While clearly an evolution in the right direction, the new 8700M GT is essentially a higher-clocked 8600M GT. This is great news for gamers looking for the best performance available, but only time will tell if this is worth the upgrade cost for current owners of the 8600M GT.
