GeForce GTX 200M, GTS 100M Series Unveiled
Reigning supreme again in the desktop segment, NVIDIA is looking forward to taking the wraps off its GeForce GTX 200M mGPU series. The new GPU series looks to up the performance offer by 50%, as claimed by the company. In the league are GeForce GTX 280M, GTX 260M and GTS 160M. Before you infer from the product names that at least two of them are based on the G200 graphics processor, let us break it to you, they're not. The entire series is based on the 55 nm G92b series. The 55 nm manufacturing technology seems to have facilitated some jumps in reference clock speeds.
In the "previous generation" GeForce 9800M series, one would note that although the high-end 9800M GTX was based on the G92 core, only 112 stream processors were made available to the GPU. With the GTX 200M series, at least one product gets to use the G92b core with all its 128 stream processors enabled. In comparison to desktop graphics cards based on G92b, the core and shader clock speeds are relatively low, but the memory clock speed gets an increment. The GTX 280M uses 128 stream processors, while the GTX 260M uses near-identical specs to those of the 9800M GTX with 112 stream processors, while the GTS 160M, comes with 64 stream processors. Interestingly, the table below shows it to be based on G92b and not G94, according to the transistor count and die-area.
NVIDIA seems to be touting these to be the fastest mGPU solutions in the making, although its comparisons don't seem to have room for ATI's Mobility Radeon HD 4800 series which is sprouting as we speak. The new GPUs are slated for March 25.
