Radeon HD 5750 512MB vs Radeon R7 250

Intro

The Radeon HD 5750 512MB comes with core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Compare all that to the Radeon R7 250, which comes with a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

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 the exact same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon HD 5750 512MB is a little bit (approximately 5%) faster with regards to texture filtering 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 using a high screen resolution 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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 maximum fill rate.
