GeForce GT 430 (OEM) vs Radeon HD 4850 1GB

Intro

Compare all of that to the Radeon HD 4850 1GB, which features a GPU core clock speed of 625 MHz, and 1024 MB of GDDR4 RAM set to run at 993 MHz through a 256-bit bus. It also is comprised of 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 13800 (123%)

Pixel Rate

The Radeon HD 4850 1GB should be quite a bit (more or less 257%) more effective at FSAA than the GeForce GT 430 (OEM), and should be capable of handling higher resolutions more effectively. (explain)

Radeon HD 4850 1GB		10000 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 7200 (257%)

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 maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
