Nvidia Geforce GTX 200M Series Revealed
 

The flagship GTX 280M is the 'full' G92, with 128 processor cores coupled with clock boosts on the core, shader & memory domains. The GTX 260M is essentially the old 9800M GTX but with higher clocks where as the GTS 160M is half the GTX 280M. Surprisingly Nvidia has opted to name the G92b flagship as GTX 280M series where as the rebranding on the desktop side for the same GPU is GTS 250M. This means that ATI will be left with the claim to the performance crown until the 40nm based products show up.
