GeForce GT 430 vs Radeon HD 5570

Intro

The GeForce GT 430 has a clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Compare those specs to the Radeon HD 5570, which comes with GPU clock speed of 650 MHz, and 512 MB of DDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5570 43 Watts
GeForce GT 430 60 Watts
Difference: 17 Watts (40%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon HD 5570 will be a bit (more or less 16%) more effective at texture filtering than the GeForce GT 430. (explain)

Radeon HD 5570 13000 Mtexels/sec
GeForce GT 430 11200 Mtexels/sec
Difference: 1800 (16%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5570 is superior to the GeForce GT 430, by a large margin. (explain)

Radeon HD 5570 5200 Mpixels/sec
GeForce GT 430 2800 Mpixels/sec
Difference: 2400 (86%)

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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could 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 Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
