A Question

Compare any two graphics cards:
VS

Geforce GTX 680 vs Geforce GTX 760

Intro

The Geforce GTX 680 uses a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this specific model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare all that to the Geforce GTX 760, which has a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is made up of 1152 SPUs, 96 TAUs, and 32 Raster Operation 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 bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Geforce GTX 680 is a lot (approximately 37%) faster with regards to 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 a high screen resolution is important to you, then the Geforce GTX 680 is a better choice, not by a very large margin though. (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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach 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.
