GeForce GTX 285 1GB vs GeForce GTX 590

Intro

The GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory runs at a frequency of 1242 MHz on this specific model. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare that to the GeForce GTX 590, which comes with a GPU core clock speed of 607 MHz, and 1536 MB of GDDR5 RAM set to run at 855 MHz through a 384-bit bus. It also features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 590 is a better choice, by a large margin. (explain)

GeForce GTX 590 58272 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 37536 (181%)

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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
