Radeon HD 5750 512MB vs Radeon R7 250

Intro

The Radeon HD 5750 512MB makes use of a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this particular model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon R7 250, which comes with a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1150 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250 65 Watts
Radeon HD 5750 512MB 86 Watts
Difference: 21 Watts (32%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon HD 5750 512MB is just a bit (approximately 5%) more effective at AF than the Radeon R7 250. (explain)

Radeon HD 5750 512MB 25200 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 1200 (5%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5750 512MB is superior to the Radeon R7 250, by far. (explain)

Radeon HD 5750 512MB 11200 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 3200 (40%)

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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
