Nvidia GeForce Go 7800GTX to launch '29 September'
Borrows Intel's 'performance per watt' message
Nvidia is borrowing Intel's new approach to chip marketing to help it promote its upcoming GeForce Go 7800GTX
So suggest allegedly leaked company presentation slides that outline the next-generation mobile graphics part and its launch on 29 September - a week on Thursday. The slides stress the chip's "revolutionary performance per watt".
According to the slides, published by TechPowerUp, the Go 7800 GTX will contains 302m transistors, some 100m of which are used to double the shader performance over the old 202m-transistor GeForce Go 6800 Ultra and raise the geometry performance by a factor of 1.6. The new chip yields double the 3DMark03 scores its predecessor did, the slides claim.
The improvements come despite a reduction in core clock speed, from the 6800 Ultra's 450MHz to 400MHz. Both chips have the same memory clock: 550MHz (1.1GHz effective). The memory is connected across a 256-bit bus. The chip delivers "99 per cent" of the performance of "shipping desktop PCs" - presumably, though this is not stated categorically, those with the desktop 7800GTX on board.
The extra transistors also equip the 7800GTX with the ability to do anti-aliasing in transparency layers. It's designed to support Windows Vista, Nvidia said.
Touting the 7800GTX's "performance per watt" - a phrase commonly spoken by Intel these days - Nvidia notes the new part will sport the latest incarnation of its PowerMizer power-conservation technology, version 6.0.
The slides claim the 7800GTX will ship with support from notebook makers Dell, Alienware, Voodoo, Sager, Falcon, Evesham, ABS, ProStar and HyperSonic. ®
