Radeon HD 5750 1GB vs Radeon R9 M270X

Intro

The Radeon HD 5750 1GB makes use of a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory works at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5750 1GB should be 2% quicker than the Radeon R9 M270X overall, due to its higher bandwidth. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M270X is a small bit (more or less 15%) better at AF than the Radeon HD 5750 1GB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 3800 (15%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M270X is superior to the Radeon HD 5750 1GB, but only just. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 5750 1GB 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 data (in units of MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
