GeForce GTX 280 vs GeForce GTX 590

Intro

The GeForce GTX 280 uses a 65 nm design. nVidia has set the core speed at 602 MHz. The GDDR3 RAM works at a frequency of 1107 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.

Compare those specifications to the GeForce GTX 590, which has clock speeds of 607 MHz on the GPU, and 855 MHz on the 1536 MB of GDDR5 RAM. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.

The GeForce GTX 590 is quite a bit (about 61%) more effective 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

The GeForce GTX 590 will be quite a bit (about 202%) faster with regards to FSAA than the GeForce GTX 280, and will be able to handle higher screen resolutions more effectively. (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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
