GeForce GTX 465 vs Radeon HD 4870 X2

Intro

The GeForce GTX 465 has a clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon HD 4870 X2, which has a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 RAM running at 900 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 465 102592 MB/sec
Difference: 127808 (125%)

Texel Rate

The Radeon HD 4870 X2 should be quite a bit (approximately 125%) faster with regards to anisotropic filtering than the GeForce GTX 465. (explain)

Radeon HD 4870 X2 60000 Mtexels/sec
GeForce GTX 465 26708 Mtexels/sec
Difference: 33292 (125%)

Pixel Rate

The Radeon HD 4870 X2 is quite a bit (more or less 24%) faster with regards to anti-aliasing than the GeForce GTX 465, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon HD 4870 X2 24000 Mpixels/sec
GeForce GTX 465 19424 Mpixels/sec
Difference: 4576 (24%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
