GeForce GTX 460 (OEM) vs Radeon HD 4790

Intro

The GeForce GTX 460 (OEM) has clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon HD 4790, which makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The GDDR5 memory runs at a speed of 800 MHz on this card. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

The GeForce GTX 460 (OEM) is a lot (about 90%) faster with regards to anisotropic filtering than the Radeon HD 4790. (explain)

GeForce GTX 460 (OEM) 36400 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 17200 (90%)

Pixel Rate

The GeForce GTX 460 (OEM) is much (more or less 117%) better at full screen anti-aliasing than the Radeon HD 4790, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 460 (OEM) 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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
