nVidia is lauching today its new high-end 3D graphics chip, GeForce 7800 GTX, which is based in a totally new core (called CineFX 4.0). Instead of using the "old" GeForce 6800 core and simpling raising its clock, nVidia decide to re-design the way instructions are processed inside the chip. Accordingly to nVidia, this led to a performance increase up to 50% in GeForce 7800 GTX compared to a GeForce 6800 Ultra running at the same clock rate – accordingly to the manufacturer, a single GeForce 7800 GTX is faster than two GeForce 6800 Ultra in SLI mode.
