Radeon HD 5750 512MB vs Radeon R9 M270X

Intro

The Radeon HD 5750 512MB uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this model. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M270X, which has core clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 512MB should in theory be just a bit better than the Radeon R9 M270X in general. (explain)

Radeon HD 5750 512MB 73600 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M270X is a little bit (approximately 15%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 5750 512MB 25200 Mtexels/sec
Difference: 3800 (15%)

Pixel Rate

The Radeon R9 M270X is a small bit (more or less 4%) more effective at full screen anti-aliasing than the Radeon HD 5750 512MB, and capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 5750 512MB 11200 Mpixels/sec
Difference: 400 (4%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past 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 RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
