GeForce GTX 650 Ti 2GB vs Radeon R9 290

Intro

Compare that to the Radeon R9 290, which makes use of a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 233600 (270%)

Texel Rate

The Radeon R9 290 is quite a bit (approximately 116%) more effective at texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R9 290		128000 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 68608 (116%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 290 is a better choice, 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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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