Radeon HD 4750 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core frequency at 825 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X should theoretically be a lot faster than the Radeon HD 4750 overall. (explain)

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

Texel Rate

The Radeon HD 4750 is a little bit (more or less 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 high levels of AA is important to you, then the Radeon HD 4750 is a better choice, and very much so. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core 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 per second.

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