GeForce GT 320 vs Radeon HD 5570

Intro

The GeForce GT 320 comes with clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 Texture Address Units and 8 ROPs.

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

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 5570 should in theory be a small bit faster 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 should be a small bit (approximately 0%) better at AF than the GeForce GT 320. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 5570 is superior to the GeForce GT 320, but it probably won't make a huge difference. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
