Radeon HD 5750 1GB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB is 2% faster than the Radeon R9 M375X in general, because of its greater data rate. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M375X should be quite a bit (about 61%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 15400 (61%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375X is a better choice, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 5040 (45%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
