GeForce GTX 465 vs Radeon HD 5570

Intro

Compare those specifications to the Radeon HD 5570, which comes with core clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of DDR3 memory. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Texel Rate

The GeForce GTX 465 will be quite a bit (more or less 105%) more effective at texture filtering than the Radeon HD 5570. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 13708 (105%)

Pixel Rate

The GeForce GTX 465 should be quite a bit (approximately 274%) more effective at AA than the Radeon HD 5570, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 14224 (274%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are applied in one second. This is worked out by multiplying the total number of texture units 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 potential to reach the maximum fill rate.
