GeForce GTX 460 SE vs Radeon HD 4850 1GB

Intro

Compare all of that to the Radeon HD 4850 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 memory runs at a speed of 993 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Radeon HD 4850 1GB		25000 Mtexels/sec
	Difference: 6200 (25%)

Pixel Rate

The GeForce GTX 460 SE will be much (approximately 108%) faster with regards to AA than the Radeon HD 4850 1GB, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 4850 1GB		10000 Mpixels/sec
	Difference: 10800 (108%)

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 (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 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 could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
