GeForce GTX 650 Ti 2GB vs GeForce GTX Titan X

Intro

Compare those specs to the GeForce GTX Titan X, which features core clock speeds of 1000 MHz on the GPU, and 1750 MHz on the 12288 MB of GDDR5 memory. It features 3072 SPUs as well as 192 TAUs and 96 ROPs.

	Difference: 249600 (289%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (more or less 223%) better at AF than the GeForce GTX 650 Ti 2GB. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 132608 (223%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan X is a better choice, by far. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 81152 (547%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 reach the maximum fill rate.
