Radeon HD 5750 1GB vs Radeon R9 M365X

Intro

Compare that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5750 1GB should in theory be a small bit faster than the Radeon R9 M365X in general. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M365X is quite a bit (more or less 47%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 11800 (47%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 3600 (32%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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