NVIDIA's GeForce 8M GPUs

NVIDIA Brings G80 to the Mobile Market


Riding on the coat-tails of Intel's Santa Rosa launch is NVIDIA with a new mobile GPU series based on the G80 technology.  NVIDIA is actually releasing five separate parts for the mobile market ranging from performance parts to the value notebooks.  For the time being, they are leaving the enthusiast notebook GPUs to the 7-series and SLI technology.

Performance


GeForce 8600M GT
GeForce 8600M GS


Mainstream


GeForce 8400M GT
GeForce 8400M GS
GeForce 8400M G


Value


GeForce 7190M + nForce 650M
GeForce 7150M + nForce 630M
GeForce 7000M + nForce 610M


Here's the overall line up as NVIDIA sees it for their mobility GPUs.  The GeForce 8600 series targets the performance notebooks which might be similar to the Asus G2P notebook we recently reviewed


The feature set of the GeForce 8M series is very similar to what we have seen on the desktop series of GeForce 8 parts: DX10 unified architecture and PureVideo HD (updated video processor as with the G84 and G86).  As you would expect with a mobility GPU, there has been updates on the power efficiency and the ability to balance power consumption and performance for longer battery life.

Here is the complete technical break down of the GeForce 8M series of chips including their number of stream processors, clock speeds, etc.  Ranging from 32 stream processors on the top of the line 8600M GT down to 8 stream processors on the 8400M G, the line up offers a pretty well spaced "stepping" platform for notebook vendors to choose the best part at the best price for them. 



This slide presented by NVIDIA compares the performance of the new 8600M GT to the previous performance part from NVIDIA, the mobility 7600.  Obviously the performance from the new G80 architecture is very impressive reaching up to 2x the performance of the original 7-series part.



The other nice improvement in the new GeForce 8M series is the inclusion of the new video processor that was introduced in the GeForce 8600 desktop cards last month.  You can see here that the CPU utilization (and then theoretically power consumption) is much better with the new G80-based cards.  This is particularly useful for any users that might be watching HD video on their notebooks and looking to extend battery life.


Overall, the new GeForce 8M series of GPUs from NVIDIA look very impressive and should complement the notebooks that decide to integrate it; regardless of Santa Rosa support or not.


Final Thoughts


Both of the announcements today, Intel's new Santa Rosa Centrino Duo/Pro platform and NVIDIA's GeForce 8M series of GPUs, improve the overall ecosystem of the mobility market by being able to increase performance and decrease power consumption in various areas.  With the main goal of mobile computing to provide as much working time as possible (or gaming, etc) on a single battery charge, these new technologies and products are edging us closer. 


We are looking forward to getting some Santa Rosa and GeForce 8M based notebooks in for testing in the very near future and reporting our results to you.
