Geforce GTX 760 vs Radeon HD 7950 3GB
Intro
The Geforce GTX 760 uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this card. It features 1152 SPUs along with 96 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 7950 3GB, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this card. It features 1792 SPUs as well as 112 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Jesus, look how behind the times compared with the 7950 the 760 is. The 7950 still beats it in IRL, even 18 months on...
The 760 is a newer card than the 7950. What are you talking about?
actually... in real world tests, the 760 would outperform a 7950 by a few fps just because of the nvidia drivers... if mantle was included in every game however, then the amd card would win..... i own an xfx radeon hd 7950, and i can say, it is a good card, but nothing compared to nvidia cards
