AMD and Nvidia are both on the same page for this holiday season with the release of their new graphics cards. 1) They started with the mobile version and 2) there is nothing really new about their new versions. AMD "rebranded" its Radeon HD 6000M series to Radeon HD 7000M series. Nvidia's GeForce 600M launch is a rebrand of GeForce 500M parts.
AMD's "new" release includes three models; HD 7600M, 7500M and 7400M. The HD 7400M looks to be based on the same Seymore XT used with the HD 6470M. The HD 7600 follows suit and looks to be based on same Whistler Pro used with the HD 6750M. The HD 7500 fits in between the HD 7600M and HD 7400M. It combines the 480 core GPU of the HD 7600M with the 64-bit memory interface of the HD 7400M. All the current 7000M models have the ability to support DDR3 or GDDR5 memory

Nvidia's new products include the GeForce GT 635M, GT 630M and 610M. The GeForce GT 630M (GT 540M) and GeForce 610M (520MX) are direct rebrands of GeForce 500M GPUs. The only difference seen in the new product is the GT 635M has a slightly more memory bandwidth than the previous GT 555M.

For most, the news of these releases are a bit of a disappointment, as we were hoping for new architecture and 28 nm based desktop GPUs. I, myself, was looking forward to going out and getting a new GTX 600 or HD 7000 for my gaming computer this holiday season. It looks like we will be waiting a little longer for these desktop models to hit the market.
