VS

Geforce GTX 680 vs Geforce GTX 760

Intro

The Geforce GTX 680 comes with core speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.

Compare those specifications to the Geforce GTX 760, which has core speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760 170 Watts
Geforce GTX 680 195 Watts
Difference: 25 Watts (15%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Geforce GTX 680 is quite a bit (more or less 37%) better at texture filtering than the Geforce GTX 760. (explain)

Geforce GTX 680 128768 Mtexels/sec
Geforce GTX 760 94080 Mtexels/sec
Difference: 34688 (37%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 680 is a better choice, though only just barely. (explain)

Geforce GTX 680 32192 Mpixels/sec
Geforce GTX 760 31360 Mpixels/sec
Difference: 832 (3%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

but thats not right, the new 760 has 1006+ mhz core speed, mofos
armin2100 says:
why nvidia 680 gtx is better?
ineedspeed says:
760's core clock is 980 mhz. This is correct. Only non reference models have more than 980.
