New mobile GPU’s from Nvidia
Nvidia has droped the ‘Go’ prefix and replaced it with an ‘M’ appearing after the model number. Leading the new lineup is the 8600M GT. As the only mobile DirectX 10 part equipped with 32 stream processors running at 950MHz, the 8600M GT is clocked at 475MHz paired with up to 512MB of memory at 1.4GHz. Like the desktop counterpart, the memory interface remains at 128bit.
Like you’d expect, the next model receives the 8600M GS name. Featuring 16 stream processor clocked at 1.2GHz, the speed compensates for the lesser shader power. While memory specifications remain the same as the GT, the core has been raised to 600MHz.
Falling through the remaining models we find the 8400M GT and GS. Both models feature 16 stream processors, the GT’s operate at 900MHz while the GS settles at 800MHz. Core clocks are 450Mhz for the GT and a 50Mhz reduction slots the GS in at 400Mhz. The two model’s memory is clocked at 1.2GHz, the GT features 512MB, and the GS falls to 256MB, this time through a 64MB bus.
Closing of the spectrum is the 8400M G. This value model is almost identical to the 8400M GS, except it features half the shader power.
“Coinciding with yesterday’s official launch of Santa Rosa, we rolled out our GeForce 8 family of notebook GPUs,” stated NVIDIA CEO Jen-Hsun Huang. “The new GeForce 8M-series notebook GPUs are the first to support DirectX 10 and 1080p decoding of full HD movies.”
