Geforce GTX 760 vs Radeon HD 7950 3GB

Intro

The Geforce GTX 760 comes with a clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon HD 7950 3GB, which comes with a GPU core clock speed of 800 MHz, and 3072 MB of GDDR5 memory set to run at 1250 MHz through a 384-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

amd PENETRATES everything

Jack Black says:

Jesus, look how behind the times compared with the 7950 the 760 is. The 7950 still beats it in IRL, even 18 months on...

Jack Black smells says:

The 760 is a newer card than the 7950. What are you talking about?

james adkins says:

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
