Geforce GTX 670 vs Geforce GTX 760

Intro

The Geforce GTX 670 makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular card. It features 1344 SPUs as well as 112 Texture Address Units and 32 ROPs.

Compare all of that to the Geforce GTX 760, which comes with core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1152 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

(No game benchmarks for this combination yet.)

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Geforce GTX 760 should in theory be a small bit faster than the Geforce GTX 670 in general. (explain)

Geforce GTX 760 192256 MB/sec
Geforce GTX 670 192000 MB/sec
Difference: 256 (0%)

Texel Rate

The Geforce GTX 670 will be a small bit (more or less 9%) better at texture filtering than the Geforce GTX 760. (explain)

Geforce GTX 670 102480 Mtexels/sec
Geforce GTX 760 94080 Mtexels/sec
Difference: 8400 (9%)

Pixel Rate

The Geforce GTX 760 should be just a bit (more or less 7%) more effective at anti-aliasing than the Geforce GTX 670, and should be capable of handling higher resolutions while still performing well. (explain)

Geforce GTX 760 31360 Mpixels/sec
Geforce GTX 670 29280 Mpixels/sec
Difference: 2080 (7%)

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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

What About the EVGA GTX 760 SC Edition?, is this HWcompare just with the reference models?
Greetings!

Bought a GTX 760 twin frozr too, it's very good, changed from a EVGA 550ti!
