Radeon HD 5750 1GB vs Radeon R7 250X

Intro

The Radeon HD 5750 1GB features a GPU core clock 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 all that to the Radeon R7 250X, which has a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB 86 Watts
Radeon R7 250X 95 Watts
Difference: 9 Watts (10%)

Memory Bandwidth

In theory, the Radeon HD 5750 1GB is 2% faster than the Radeon R7 250X in general, because of its higher bandwidth. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R7 250X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R7 250X will be a lot (about 59%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon R7 250X 40000 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 14800 (59%)

Pixel Rate

The Radeon R7 250X should be quite a bit (approximately 43%) faster with regards to anti-aliasing than the Radeon HD 5750 1GB, and should be able to handle higher resolutions while still performing well. (explain)

Radeon R7 250X 16000 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 4800 (43%)

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 (measured in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should 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, HDR and higher screen 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 by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
