GeForce GTX 280 vs GeForce GTX 590

Intro

The GeForce GTX 280 has clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 590, which has a clock frequency of 607 MHz and a GDDR5 memory speed of 855 MHz. It also features a 384-bit memory bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 TAUs, and 48 ROPs.

GeForce GTX 280 141696 MB/sec
Difference: 186624 (132%)

Texel Rate

The GeForce GTX 590 should be quite a bit (more or less 61%) better at anisotropic filtering than the GeForce GTX 280. (explain)

GeForce GTX 590 77696 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 29536 (61%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 590 is superior to the GeForce GTX 280, by a large margin. (explain)

GeForce GTX 590 58272 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 39008 (202%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
