Radeon R7 250 vs Radeon R7 250X 2GB

Intro

The Radeon R7 250 comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare all that to the Radeon R7 250X 2GB, which has GPU core speed of 1000 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250 65 Watts
Radeon R7 250X 2GB 95 Watts
Difference: 30 Watts (46%)

Memory Bandwidth

As far as performance goes, the Radeon R7 250 should in theory be just a bit superior to the Radeon R7 250X 2GB overall. (explain)

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

Texel Rate

The Radeon R7 250X 2GB will be much (approximately 67%) more effective at AF than the Radeon R7 250. (explain)

Radeon R7 250X 2GB 40000 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 16000 (67%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 250X 2GB is a better choice, and very much so. (explain)

Radeon R7 250X 2GB 16000 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 8000 (100%)

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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 that the graphics 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 Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
