GeForce GTX 650 Ti 2GB vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which features a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

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

Performance-wise, the GeForce GTX 650 Ti 2GB should theoretically be just a bit better than the Radeon R7 250X overall. (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 should be a lot (more or less 48%) more effective at texture 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 using high levels of AA is important to you, then the Radeon R7 250X is the winner, but not by far. (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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
