GeForce GTX 660 Ti vs Radeon HD 5870
Intro
The GeForce GTX 660 Ti has a clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.Compare those specifications to the Radeon HD 5870, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a frequency of 1200 MHz on this model. It features 1600(320x5) SPUs as well as 80 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type 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 amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to 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.
