GeForce GT 320 vs Radeon HD 5570

Intro

The GeForce GT 320 has core clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs along with 24 TAUs and 8 ROPs.

Compare all that to the Radeon HD 5570, which has a core clock speed of 650 MHz and a DDR3 memory speed of 900 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon HD 5570 should in theory be a small bit better than the GeForce GT 320 in general. (explain)

Radeon HD 5570 28800 MB/sec
GeForce GT 320 25280 MB/sec
Difference: 3520 (14%)

Texel Rate

The Radeon HD 5570 will be a small bit (more or less 0%) more effective at texture filtering than the GeForce GT 320. (explain)

Radeon HD 5570 13000 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 40 (0%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 5570 is superior to the GeForce GT 320, though only just barely. (explain)

Radeon HD 5570 5200 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 880 (20%)

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 data (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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