Radeon HD 5750 512MB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5750 512MB should in theory perform just a bit faster than the Radeon R7 M260X overall. (explain)

Radeon HD 5750 512MB		73600 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The Radeon HD 5750 512MB should be a lot (more or less 27%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon HD 5750 512MB		25200 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5400 (27%)

Pixel Rate

The Radeon HD 5750 512MB will be much (approximately 70%) faster with regards to anti-aliasing than the Radeon R7 M260X, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 5750 512MB		11200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 4600 (70%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
