GeForce GTX 460 SE vs Radeon HD 6570 (OEM) 1GB

Intro

Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR3 memory works at a frequency of 900 MHz on this particular card. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

The GeForce GTX 460 SE is much (approximately 100%) more effective at texture filtering than the Radeon HD 6570 (OEM) 1GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 15600 (100%)

Pixel Rate

The GeForce GTX 460 SE should be quite a bit (more or less 300%) faster with regards to anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and also capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 15600 (300%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 ability to reach the max fill rate.
