GeForce GTX 275 vs GeForce GTX 460 1GB

Intro

The GeForce GTX 275 features a clock frequency of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also features a 448-bit memory bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Compare those specifications to the GeForce GTX 460 1GB, which has GPU core speed of 675 MHz, and 1024 MB of GDDR5 RAM set to run at 900 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 460 1GB 115200 MB/sec
Difference: 11808 (10%)

Texel Rate

The GeForce GTX 275 will be a lot (more or less 34%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce GTX 275 50640 Mtexels/sec
GeForce GTX 460 1GB 37800 Mtexels/sec
Difference: 12840 (34%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 1GB is superior to the GeForce GTX 275, and very much so. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
GeForce GTX 275 17724 Mpixels/sec
Difference: 3876 (22%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 the card's 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
