Radeon HD 7750 vs Radeon R7 M260X

Intro

The Radeon HD 7750 has a clock speed of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 512 SPUs, 32 TAUs, and 16 ROPs.

Compare those specs to the Radeon R7 M260X, which comes with core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7750 should be 13% faster than the Radeon R7 M260X in general, due to its greater data rate. (explain)

Radeon HD 7750 72000 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon HD 7750 should be quite a bit (about 29%) better at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon HD 7750 25600 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 5800 (29%)

Pixel Rate

The Radeon HD 7750 will be much (approximately 94%) more effective at anti-aliasing than the Radeon R7 M260X, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 7750 12800 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 6200 (94%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of 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.
