VS

GeForce GTX 285 1GB vs GeForce GTX 590

Intro

The GeForce GTX 285 1GB features core speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 285 1GB 204 Watts
GeForce GTX 590 365 Watts
Difference: 161 Watts (79%)

Memory Bandwidth

Theoretically, the GeForce GTX 590 should perform quite a bit faster than the GeForce GTX 285 1GB overall. (explain)

GeForce GTX 590 328320 MB/sec
GeForce GTX 285 1GB 158976 MB/sec
Difference: 169344 (107%)

Texel Rate

The GeForce GTX 590 will be much (about 50%) faster with regards to texture filtering than the GeForce GTX 285 1GB. (explain)

GeForce GTX 590 77696 Mtexels/sec
GeForce GTX 285 1GB 51840 Mtexels/sec
Difference: 25856 (50%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 590 is the winner, by far. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
