GeForce GTX 650 Ti 2GB vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which makes use of a 28 nm design. nVidia has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this card. It features 3072 SPUs as well as 192 TAUs and 96 Rasterization Operator Units.

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX Titan X		250 Watts
	Difference: 140 Watts (127%)

Memory Bandwidth

In theory, the GeForce GTX Titan X will be 289% quicker than the GeForce GTX 650 Ti 2GB in general, because of its higher data rate. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 249600 (289%)

Texel Rate

The GeForce GTX Titan X is a lot (approximately 223%) more effective at texture filtering 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

The GeForce GTX Titan X is quite a bit (more or less 547%) better at full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and also capable of handling higher screen resolutions while still performing well. (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 transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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