Radeon HD 5770 vs Radeon R7 M260X

Intro

The Radeon HD 5770 uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.

Compare all that to the Radeon R7 M260X, which has a core clock speed of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5770 will be 20% quicker than the Radeon R7 M260X overall, due to its higher bandwidth. (explain)

Radeon HD 5770 76800 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 12800 (20%)

Texel Rate

The Radeon HD 5770 will be much (approximately 72%) more effective at AF than the Radeon R7 M260X. (explain)

Radeon HD 5770 34000 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 14200 (72%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5770 is a better choice, by a large margin. (explain)

Radeon HD 5770 13600 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 7000 (106%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
