GeForce GTX 465 vs Radeon HD 4790

Intro

The GeForce GTX 465 has a GPU clock speed of 607 MHz, and the 1024 MB of GDDR5 RAM is set to run at 802 MHz through a 256-bit bus. It also is made up of 352 Stream Processors, 44 Texture Address Units, and 32 ROPs.

Compare all of that to the Radeon HD 4790, which comes with a core clock frequency of 600 MHz and a GDDR5 memory speed of 800 MHz. It also uses a 256-bit bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 465 should theoretically be a little bit better than the Radeon HD 4790 overall. (explain)

GeForce GTX 465 102592 MB/sec
Radeon HD 4790 102400 MB/sec
Difference: 192 (0%)

Texel Rate

The GeForce GTX 465 will be quite a bit (approximately 39%) more effective at anisotropic filtering than the Radeon HD 4790. (explain)

GeForce GTX 465 26708 Mtexels/sec
Radeon HD 4790 19200 Mtexels/sec
Difference: 7508 (39%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 465 is a better choice, by far. (explain)

GeForce GTX 465 19424 Mpixels/sec
Radeon HD 4790 9600 Mpixels/sec
Difference: 9824 (102%)

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 information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
