GeForce GTX 570 vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which features core speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 RAM. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 570		219 Watts
	Difference: 197 Watts (895%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 should be 1800% quicker than the Radeon HD 4350 overall, because of its higher bandwidth. (explain)

GeForce GTX 570		152000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 144000 (1800%)

Texel Rate

The GeForce GTX 570 will be quite a bit (more or less 855%) better at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GTX 570		43920 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 39320 (855%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 570 is a better choice, by a large margin. (explain)

GeForce GTX 570		29280 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 26980 (1173%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
