for those who are confused by NVIDIA NVS 3100/5100m

Here is the link from Nvidia's Chinese site:

Why the Chinese website?

it should be noted, that at least based on benchmarks,
the 3100m compared to the quadro 140m used in the T61, (16 shaders)
this has 16 shaders as well, at roughly the same clock speed, on the same 64 bit bus. but is roughly twice as fast, for 5 (50% more) extra watts of TDP. (also, 40 vs 80nm dies)
and compared to the 3470 (40 lesser shaders), it is still quite a bit faster.

 

A shader unit by AMD is different from a shader unit by nvidia. AMD shader units are smaller than nvidia shader units. A 128 bit memory bus gpu would have been great.

 

hence "lesser shaders" as nvidias are more effecient and getting better, as evidenced by this chip vs older 16 shader chips.

 

blackomegax is right the nvidia (3100m) looks like it's quite a bit faster than the ati (3470) from last generation. If you look at the benchmark scores, check out this link:

Check out the positional ranking here (3100m ranks 104 and 3470 ranks 139):

the speed of the GPU and CPU option would always increase from one generation to the next, if it didn't then there would little incentives to force people to upgrade to the new products.
