Radeon HD 5750 1GB vs Radeon R7 250

Intro

The Radeon HD 5750 1GB uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a speed of 1150 MHz on this specific card. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon R7 250, which has a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 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 1GB 86 Watts
Difference: 21 Watts (32%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon HD 5750 1GB is a small bit (about 5%) faster with regards to AF than the Radeon R7 250. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is superior to the Radeon R7 250, by a large margin. (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
