Most Geforce 600 mobile GPUs are still Fermi

[Valentin N]

We hoped that most new 600-series mobile Geforce will be based on the new, energy efficient Kepler architecture. Sadly, we were wrong and the series is still dominated by rebranded Fermi products.

To summarize it all, it seems that only Gefore 640M, Geforce 640M LE, Geforce 650m and Geforce GTX 660M are based on the new architecture under the code name Kepler. The rest are based on the previous generation architecture code name, Fermi.

So don't get fooled by the new names.

So that these would be great for gaming?

They would; on par with GTX 570M, from the amount of CUDA cores, the only bottleneck the rams bandwith.

In more simpler terms?

More simple... It has more cores, so called CUDA cores that will result to increased perform compared to the models that has same names -100 (Geforce 640M LE is new), so I believe at least. The bandwidth has big influence how well the gpu performance and most of the new gpu only have 128bit, and maybe only GDDR3 compared to GDDR5 that has double the bandwidth that GGDR3 has.

Ahh. So for gaming then it would make the performance ultra good. Not good with the hardware xD

I wouldn't say ultra good but good for being in a laptop. It will however be ultragood for the ultrabooks that might have Geforce 640M LE, together with a quacore with TDP value of 35W. Gigabytes will without doubt have such gpu.
