GeForce GTX 650 Ti vs Radeon R9 M290X

Intro

Compare that to the Radeon R9 M290X, which has GPU core speed of 850 MHz, and 4096 MB of GDDR5 RAM set to run at 1200 MHz through a 256-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.

Radeon R9 M290X		100 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 10 Watts (10%)

Memory Bandwidth

In theory, the Radeon R9 M290X should perform quite a bit faster than the GeForce GTX 650 Ti in general. (explain)

Radeon R9 M290X		153600 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 67200 (78%)

Texel Rate

The Radeon R9 M290X is a small bit (more or less 14%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti. (explain)

Radeon R9 M290X		68000 Mtexels/sec
GeForce GTX 650 Ti		59392 Mtexels/sec
	Difference: 8608 (14%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M290X is a better choice, by far. (explain)

Radeon R9 M290X		27200 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 12352 (83%)

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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
