NVIDIA has announced its response to much of AMD’s Radeon HD 6000M series, in the form of “new” GeForce 500M notebook GPUs. The GeForce 400M has been around for barely a quarter, so no major improvements are expected. In fact, the first GeForce 500M cards are based on the same GF106/8 chips powering the GeForce 400M cards it replaces. In addition, a new flagship is released, branded GeForce GTX 485M. It is a fully unlocked 384SP GF104, clocked at 575 MHz. While a TDP is not revealed, there’s no doubt the new flagship is expected to be extremely hot.

there’s no doubt the new flagship is expected to be extremely hot.

Coming back to the GeForce 500M cards, the cards announced today comprise of the GT 500M series. The GeForce GT 555M is based on GF106, with very similar specifications to the outgoing 192-bit GeForce GT 445M. The GT 555M is followed by a slew of GF106-based cards, namely GT 520M and GT 525M (for mainstream users) and GT 540M and GT 550M (for performance users). All the four cards are based on GF106 with varying combinations of disabled units / clock speeds / memory bus.

Complementing these is another new GF108 chip, branded GeForce GT 410M. A GeForce GT 315M is also released, based on the ancient entry level chip GT218. So, there you have it, seven different chips released across three different generations – it couldn’t get more confusing!

The GTS 500M and GTX 500M series are yet to be announced. Hopefully, they will be based on GF11x derivatives powering the desktop GeForce 500 family.

NVIDIA’s USP for the GeForce 500M is definitely Optimus. NVIDIA claim a very impressive 200+ design wins for Sandy Bridge based laptops.
