Radeon HD 5750 512MB vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which has GPU core speed of 1015 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5750 512MB should in theory be just a bit faster than the Radeon R9 M375X overall. (explain)

Radeon HD 5750 512MB		73600 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M375X should be a lot (approximately 61%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 15400 (61%)

Pixel Rate

The Radeon R9 M375X should be quite a bit (approximately 45%) more effective at FSAA than the Radeon HD 5750 512MB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon HD 5750 512MB		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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
