GeForce GT 450 (OEM) vs GeForce GTX 650 Ti

Intro

Compare that to the GeForce GTX 650 Ti, which features a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti is quite a bit (about 213%) better at AF than the GeForce GT 450 (OEM). (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 40432 (213%)

Pixel Rate

The GeForce GT 450 (OEM) is a lot (more or less 28%) more effective at FSAA than the GeForce GTX 650 Ti, and also should be able to handle higher resolutions better. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 650 Ti		14848 Mpixels/sec
	Difference: 4112 (28%)

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 data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
