How Well Did We Do?

After loads of tests, we finally pegged the maximum stable clock speeds of our GeForce GTX 280 at 693 MHz core and 1323 MHz RAM. This means we managed to overclock the GPU by 91 MHz (15%), the shaders by 215 MHz (15%) and the GDDR3 memory by 216 MHz (19.5 %). Not bad at all!

Now, let's take a look at how the overclocked GeForce GTX 280 compares to the stock GeForce GTX 280 and a selection of other cards.

Thanks to the overclock, this GeForce GTX 280 has a memory bandwidth of almost 170 GB/s. That's 47% higher than the already phenomenal memory bandwidth of the ATI Radeon HD 4870. The core overclock gave it 54% more texture fillrate than the ATI Radeon HD 4870 but with a slightly (7.6%) lower pixel fillrate.

Alright, let's give the overclocked GeForce GTX 280 a spin and see how well it does against the standard GeForce GTX 280, the dual-GPU GeForce GTX 295, the GeForce GTX 260 and the ATI Radeon HD 4870. We will also examine which is more important - the GPU overclock or the memory overclock.
