GeForce GTX 460 vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Texel Rate

The Radeon R7 250X will be a little bit (more or less 6%) more effective at AF than the GeForce GTX 460. (explain)

Radeon R7 250X		40000 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 2200 (6%)

Pixel Rate

The GeForce GTX 460 is just a bit (about 1%) more effective at AA than the Radeon R7 250X, and should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 200 (1%)

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 max amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
