GeForce GTX 460 SE vs Radeon HD 4790

Intro

Compare those specifications to the Radeon HD 4790, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR5 memory is set to run at a frequency of 800 MHz on this model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 460 SE should perform a small bit faster than the Radeon HD 4790 overall. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 4790		102400 MB/sec
	Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 SE is a lot (about 63%) faster with regards to texture filtering than the Radeon HD 4790. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 12000 (63%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 SE is superior to the Radeon HD 4790, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 4790		9600 Mpixels/sec
	Difference: 11200 (117%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
