Radeon HD 5750 1GB vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which features a core clock frequency of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB is 130% quicker than the Radeon R7 M265 in general, due to its higher bandwidth. (explain)

Radeon HD 5750 1GB		73600 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 41600 (130%)

Texel Rate

The Radeon HD 5750 1GB should be quite a bit (more or less 45%) more effective at texture filtering than the Radeon R7 M265. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 7800 (45%)

Pixel Rate

The Radeon HD 5750 1GB should be a lot (more or less 93%) more effective at FSAA than the Radeon R7 M265, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 5400 (93%)

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 (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
