Compare any two graphics cards:
GeForce GTX 660 Ti vs Radeon HD 5870
IntroThe GeForce GTX 660 Ti has a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory is set to run at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 TAUs, and 24 ROPs.Compare those specs to the Radeon HD 5870, which features a core clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 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 small bit faster than the GeForce GTX 660 Ti overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be quite a bit (approximately 51%) better at anisotropic filtering than the Radeon HD 5870. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5870 is the winner, by a large margin. (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 data (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill 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 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.
