GeForce GT 320 vs Radeon HD 5570

Intro

Compare those specs to the Radeon HD 5570, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 memory works at a speed of 900 MHz on this specific card. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon HD 5570 should be a little bit faster than the GeForce GT 320 overall. (explain)

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

Texel Rate

The Radeon HD 5570 should be just a 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

The Radeon HD 5570 is just a bit (more or less 20%) faster with regards to FSAA than the GeForce GT 320, and capable of handling higher resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
