The Geforce GTX 260 similar to the GeForce GTX 280 as a graphics card of the other. The only external difference is the power connections. Instead of an eight-pole and six-pole needs the GTX 260 "only" two six-pin. Electricity demand falls from a maximum of 236 to 183 watts. Reason: Instead of 240 shader units like the GTX 280 has the GTX 260 only 192. In addition, the clock frequencies were slightly reduced and the memory bus width of 512 bits evaporated to 448 bits wide. Despite nominally less power the fan towards the holding GTX 280 no way back. Both cooling system turn into clearly audible range - that has made the 8800 generation better.
In our benchmarks with a Core 2 Quad QX6850 and 2.0 GByte DDR2-RAM on the motherboard Foxconn Mars with P35 chipset leads to a residue of about 20 percent compared to the GTX 280. Example Crysis with high details: In 1680x1050 the GTX 280 reaches liquid playable 41.8 fps, the GTX 260 comes to almost evenly matched 37.5 fps. In the extreme setting of 2560x1600 with eight-time anti-aliasing and 16x anisotropic texture filtering wins GTX 280 significantly with 20.6 to 15.5 frames per second. While only a few play on a 30-inch display. But because it depends at this stage solely on the graphics card, it shows very well the theoretical performance difference.
Bottom line offers the GTX 260 but clearly the better price-performance ratio: While the GTX 280 delivers only 0.12 fps per euro, comes the 310-euro GTX 260 0.18 fps per euro. The pure performance comparison to a GeForce 9800 GX2 loses GTX 260 even - the nearly 400-euro GX2 expects almost as fast as the GTX 280, However, based on the problem-prone SLI concept.
