Based on the appearance in the above images, the GT 750M uses GK106, only itвЂ™s what would be called a вЂњfloor sweeperвЂќ model: any GK106 chip with too many defective cores to be used elsewhere can end up configured basically the same as GK107. One final item of interest is that while the GT 750M appears to have a similar configuration to the other GPUs-384 cores, 128-bit memory interface-at least in the chip shots provided the GT 750M uses a different GPU core. As for the Boost clocks, in practice that can increase the GPU core speed 15% or more over the normal value, with most games realizing a 10-15% performance thanks to the increase. Presumably, most (all?) currently planned GT 750M and GT 745M laptops are using GDDR5 memory, and thus we donвЂ™t see the higher core clocks. Thus, we could see a GT 740M with 2.5GHz GDDR5 and a moderate core clock, another GT 740M with 2.0GHz GDDR5 and a slightly higher core clock, and a third variant with 1800MHz DDR3 but matched to a 980MHz core clock. With both GDDR5 and DDR3 variants available, NVIDIA wants to keep performance of chips in the same name within 10% of each other.

YouвЂ™ll note that the core clocks appear to be a little crazy, but this is based largely on how the OEMs choose to configure a specific laptop. Overall, performance of these new 700M parts should be up 15-25% relative to the previous models, thanks to higher GPU and memory clock speeds. I wish NVIDIA would just drop support for DDR3 on their higher end chips, and likewise the вЂњup toвЂќ clauses arenвЂ™t really helpful, but theyвЂ™re both necessary evils thanks to working with OEMs that sometimes have slightly different requirements. If I had to guess, I expect weвЂ™ll see revised high-end 700M parts sometime later this year based on tweaked GK106 and GK104 chips-like maybe a GTX 780M that has the performance of the GTX 680MX but in the power envelope of the GTX 680M-but weвЂ™ll have to wait and see what happens.Д¬ompared to the previous generation GTX 660M, GT 650M, GT645M, and GT 640M (not to mention the GT 640M LE), the new chips all have the same core set of features but now with GPU Boost 2.0 and higher memory clocks.
