Radeon HD 5750 1GB vs Radeon R7 250

Intro

The Radeon HD 5750 1GB comes with a GPU core speed of 700 MHz, and the 1024 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon R7 250, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this particular card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250 65 Watts
Radeon HD 5750 1GB 86 Watts
Difference: 21 Watts (32%)

Memory Bandwidth

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

Texel Rate

The Radeon HD 5750 1GB is a small bit (more or less 5%) better at texture filtering than the Radeon R7 250. (explain)

Radeon HD 5750 1GB 25200 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 1200 (5%)

Pixel Rate

The Radeon HD 5750 1GB will be a lot (about 40%) faster with regards to AA than the Radeon R7 250, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon HD 5750 1GB 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
