Compare any two graphics cards:
VS

Geforce GTX 670 vs Radeon HD 7850

Intro

The Geforce GTX 670 comes with a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It features 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon HD 7850, which has GPU clock speed of 860 MHz, and 2048 MB of GDDR5 RAM running at 1200 MHz through a 256-bit bus. It also is made up of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

I have recently bought GTX 670...due to HD 7850 wasn't enough powerfull to max out my brand new Crysis 3 game!
I was Between GTX 670 and HD 7970 but considering that GTX 670 is using much lower power consumption and have more overclock stabillity than HD 7970 was the reason that i bought GTX 670!!!

Both cards are great if you play sport/rpg/simulator/strategy games then go for AMD if you play games like Battlefield 3 or Crysis 3 or Batman Arkham city then nVidia all the way!
Moreover nVidia drivers are much better than ATi's is!
