Radeon R7 250 vs Radeon R7 250X 2GB

Intro

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

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

Memory Bandwidth

The Radeon R7 250, in theory, should perform a small bit faster than 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 should be quite a bit (approximately 67%) better at anisotropic filtering 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 screen resolution is important to you, then the Radeon R7 250X 2GB is superior to the Radeon R7 250, by a large margin. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
