GeForce GTX 285 1GB vs GeForce GTX 570

Intro

The GeForce GTX 285 1GB features a core clock speed of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also features a 512-bit memory bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 32 ROPs.

Compare all that to the GeForce GTX 570, which comes with core clock speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 memory. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

GeForce GTX 570 152000 MB/sec
Difference: 6976 (5%)

Texel Rate

The GeForce GTX 285 1GB is just a bit (more or less 18%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)

GeForce GTX 285 1GB 51840 Mtexels/sec
GeForce GTX 570 43920 Mtexels/sec
Difference: 7920 (18%)

Pixel Rate

The GeForce GTX 570 will be quite a bit (approximately 41%) better at FSAA than the GeForce GTX 285 1GB, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 570 29280 Mpixels/sec
GeForce GTX 285 1GB 20736 Mpixels/sec
Difference: 8544 (41%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If 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 higher screen resolutions.

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

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