Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 5870
IntroThe GeForce GTX 660 Ti features clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs along with 112 TAUs and 24 ROPs.Compare those specs to the Radeon HD 5870, which features a clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 1600(320x5) SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5870, in theory, should be a bit faster than the GeForce GTX 660 Ti in general. (explain)
Texel RateThe GeForce GTX 660 Ti is quite a bit (about 51%) better at AF than the Radeon HD 5870. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5870 is superior to the GeForce GTX 660 Ti, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

@nyiko .. it does, and like so many of ATi cards of recent years, they're still able to compete against - and often better - the far newer tech' from NVIDIA of a the same / similar price bracket.
Just swapped my Sapphire 5870 for an Asus GTX 660 Ti to play Ark. Huge difference in terms of framerate.
5870: ran at 1280x1024 with everything on low to get 15-20 fps.
660 Ti: running 1600x1200, with most settings at medium or high, and I get a comfy 30+ fps.
