GeForce GTX 660 Ti vs Radeon HD 5870
Intro
The GeForce GTX 660 Ti comes with a GPU core speed of 915 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 TAUs, and 24 Raster Operation Units.Compare all that to the Radeon HD 5870, which has a clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 1600(320x5) SPUs, 80 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied per second. This figure 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 graphics card will be at handling 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 the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to 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.
