Radeon HD 6770 1GB vs Radeon R9 M265X

Intro

The Radeon HD 6770 1GB makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 RAM runs at a frequency of 1050 MHz on this card. It features 800 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Compare all that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 6770 1GB 67200 MB/sec
Difference: 4800 (7%)

Texel Rate

The Radeon HD 6770 1GB is much (about 57%) more effective at AF than the Radeon R9 M265X. (explain)

Radeon HD 6770 1GB 36000 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 13000 (57%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is a better choice, by a large margin. (explain)

Radeon HD 6770 1GB 14400 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 5200 (57%)

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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
