Geforce GTX 760 vs Radeon HD 7950 3GB

Intro

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

Compare all that to the Radeon HD 7950 3GB, which features a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 1792 SPUs, 112 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max 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
