GeForce GTX 650 Ti 2GB vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this specific card. It features 2688 SPUs as well as 224 Texture Address Units and 48 ROPs.

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan should in theory be much better than the GeForce GTX 650 Ti 2GB overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 201984 (234%)

Texel Rate

The GeForce GTX Titan is quite a bit (more or less 216%) better at AF than the GeForce GTX 650 Ti 2GB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 128096 (216%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX Titan is the winner, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 25328 (171%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
