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 RAM runs at a speed of 1250 MHz on this model. It features 384 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Compare all of that to the Geforce GTX 760, which has GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum 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?
