GeForce GT 430 vs Radeon HD 5570

Intro

The GeForce GT 430 features a GPU core clock speed of 700 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 ROPs.

Compare all of that to the Radeon HD 5570, which uses a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 memory runs at a frequency of 900 MHz on this card. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

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 the exact same bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon HD 5570 will be a small bit (about 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 using lots of anti-aliasing 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen 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 amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
