Radeon HD 5770 vs Radeon R9 M275X

Intro

The Radeon HD 5770 features a clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Compare all of that to the Radeon R9 M275X, which has GPU clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 5770 76800 MB/sec
Radeon R9 M275X 72000 MB/sec
Difference: 4800 (7%)

Texel Rate

The Radeon R9 M275X will be a bit (about 6%) faster with regards to AF than the Radeon HD 5770. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 2000 (6%)

Pixel Rate

The Radeon R9 M275X is a little bit (more or less 6%) faster with regards to AA than the Radeon HD 5770, and should be capable of handling higher screen resolutions better. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 800 (6%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
