GeForce GTX 660 Ti vs Radeon HD 5870
Intro
The GeForce GTX 660 Ti has a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory runs at 1500 MHz through a 192-bit bus. It also is comprised of 1344 SPUs, 112 TAUs, and 24 ROPs.Compare all that to the Radeon HD 5870, which comes with clock speeds of 850 MHz on the GPU, and 1200 MHz on the 1024 MB of GDDR5 memory. It features 1600(320x5) SPUs along with 80 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum 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.
