GeForce GTX 650 vs Geforce GTX 760

Intro

The GeForce GTX 650 has a clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specs to the Geforce GTX 760, which uses a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this card. It features 1152 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability 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?
