GeForce GTX 650 Ti 2GB vs Radeon R7 250X

Intro

Compare all that to the Radeon R7 250X, which features a clock frequency of 1000 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 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

The GeForce GTX 650 Ti 2GB, in theory, should perform a little bit faster 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 (approximately 48%) better at AF 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 lots of anti-aliasing is important to you, then the Radeon R7 250X is superior to the GeForce GTX 650 Ti 2GB, 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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
