GeForce GTX 650 Ti 2GB vs Radeon R7 250X

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
GeForce GTX 650 Ti 2GB		110 Watts
	Difference: 15 Watts (16%)

Memory Bandwidth

The GeForce GTX 650 Ti 2GB, in theory, should be a small bit faster than the Radeon R7 250X in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be quite a bit (about 48%) better at anisotropic filtering than the Radeon R7 250X. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 19392 (48%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250X is superior to the GeForce GTX 650 Ti 2GB, not by a very large margin though. (explain)

Radeon R7 250X		16000 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1152 (8%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
