Five new high-end products have made their way into Nvidia's mobile graphics processor line. The GeForce 9700M GT, 9700M GTS, 9800M GTS, 9800M GT, and 9800M GTX complete the rest of the GeForce 9M lineup, which was introduced last month, and their specifications look a little something like this:
|Mobile GPU||SPs||GigaFLOPS||Mem. interface width||Mem. bandwidth||GeForce Boost||Hybrid Power|
|GeForce 9800M GTX||112||420||256-bit||51GB/s||No||Yes|
|GeForce 9800M GT||96||360||256-bit||51GB/s||No||Yes|
|GeForce 9800M GTS||64||240||256-bit||51GB/s||No||Yes|
|GeForce 9700M GTS||48||180||256-bit||51GB/s||No||Yes|
|GeForce 9700M GT||32||148||256-bit||26GB/s||No||Yes|
No, that's not a typo. The GeForce 9800M GT actually has better specs than the 9800M GTS, pretty much defying the naming convention Nvidia usually applies to its desktop graphics cards.
At the top end of the new mobile GPU line, the GeForce 9800M GTX seems to have most in common with the desktop GeForce 8800 GT: both have 112 stream processors and 256-bit memory interfaces, while the 8800 GT has slightly higher memory bandwidth (57.6GB/s) and a 504 gigaFLOPS floating-point arithmetic rating. The 9800M GTS corresponds to the desktop GeForce 9600 GT in much the same way, with the same stream processor count and memory interface width, but lower memory bandwidth (51GB/s instead of 57.6GB/s) and a lower gigaFLOPS rating (240 instead of 312).
Otherwise, these new GeForce 9700M and 9800M models share many of the same goodies as their other 9M-series brethren, including HybridPower support—a feature that lets a notebook's integrated GPU take over for the discrete graphics board to save power.
