GeForce GTX 650 Ti 2GB vs Radeon R9 290

Intro

Compare all that to the Radeon R9 290, which has a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 512-bit bus, and uses a 28 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 290 is the winner, and very much so. (explain)

Radeon R9 290		51200 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 36352 (245%)

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 (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
