Radeon R9 M275X 72000 MB/sec
Radeon HD 6570 (OEM) 2GB 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M275X should be much (more or less 131%) better at AF than the Radeon HD 6570 (OEM) 2GB. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon HD 6570 (OEM) 2GB 15600 Mtexels/sec
Difference: 20400 (131%)

Pixel Rate

The Radeon R9 M275X is quite a bit (approximately 177%) better at AA than the Radeon HD 6570 (OEM) 2GB, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon HD 6570 (OEM) 2GB 5200 Mpixels/sec
Difference: 9200 (177%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
