Radeon HD 7770 vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which features core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7770 should be a little bit faster than the Radeon R7 M260X in general. (explain)

Radeon HD 7770		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon HD 7770 will be quite a bit (approximately 102%) more effective at AF than the Radeon R7 M260X. (explain)

Radeon HD 7770		40000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 20200 (102%)

Pixel Rate

The Radeon HD 7770 is much (approximately 142%) more effective at anti-aliasing than the Radeon R7 M260X, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 7770		16000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9400 (142%)

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

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
