GeForce GTS 250 512MB vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which features core speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Texel Rate

The GeForce GTS 250 512MB should be just a bit (approximately 18%) faster with regards to AF than the Radeon R7 250X. (explain)

GeForce GTS 250 512MB		47232 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 7232 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 250X is superior to the GeForce GTS 250 512MB, by far. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce GTS 250 512MB		11808 Mpixels/sec
	Difference: 4192 (36%)

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 (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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