GeForce GTX 650 vs Geforce GTX 760

Intro

The GeForce GTX 650 makes use of a 28 nm design. nVidia has set the core speed at 1058 MHz. The GDDR5 memory works at a speed of 1250 MHz on this specific card. It features 384 SPUs as well as 32 Texture Address Units and 16 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 Stream Processors, 96 TAUs, and 32 ROPs.

In theory, the Geforce GTX 760 should be 140% faster than the GeForce GTX 650 in general, due to its greater data rate. (explain)

Geforce GTX 760 192256 MB/sec
GeForce GTX 650 80000 MB/sec
Difference: 112256 (140%)

Texel Rate

The Geforce GTX 760 should be much (approximately 178%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Geforce GTX 760 94080 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 60224 (178%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, and very much so. (explain)

Geforce GTX 760 31360 Mpixels/sec
GeForce GTX 650 16928 Mpixels/sec
Difference: 14432 (85%)

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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.

Tesla says:

Can someone explain why does the GTX 650 have DX11.1 as opposed to GTX 760's DX11? Also, how does the first one benefit from the faster core and shader speed, being generally weaker than the second one?
