GeForce GT 430 (OEM) vs Radeon HD 5870

Intro

Compare those specifications to the Radeon HD 5870, which has a core clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 1600(320x5) SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 (OEM)		60 Watts
Radeon HD 5870		188 Watts
	Difference: 128 Watts (213%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5870 is 433% faster than the GeForce GT 430 (OEM) in general, due to its greater data rate. (explain)

Radeon HD 5870		153600 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 124800 (433%)

Texel Rate

The Radeon HD 5870 should be a lot (about 507%) better at AF than the GeForce GT 430 (OEM). (explain)

Radeon HD 5870		68000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 56800 (507%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5870 is the winner, and very much so. (explain)

Radeon HD 5870		27200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 24400 (871%)

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 data (in units of MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
