Radeon HD 4750 vs Radeon R7 M260X

Intro

The Radeon HD 4750 makes use of a 40 nm design. AMD has clocked the core speed at 730 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this model. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Compare those specs to the Radeon R7 M260X, which has a clock frequency 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 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X should be 25% quicker than the Radeon HD 4750 in general, due to its higher bandwidth. (explain)

Radeon R7 M260X 64000 MB/sec
Radeon HD 4750 51200 MB/sec
Difference: 12800 (25%)

Texel Rate

The Radeon HD 4750 is just a bit (about 18%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon HD 4750 23360 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 3560 (18%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 4750 is the winner, by a large margin. (explain)

Radeon HD 4750 11680 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 5080 (77%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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