GeForce GT 450 (OEM) vs GeForce GTX 650 Ti 2GB

Intro

Compare those specs to the GeForce GTX 650 Ti 2GB, which makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this particular model. It features 768 SPUs along with 64 Texture Address Units and 16 ROPs.

GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be much (approximately 213%) more effective at AF than the GeForce GT 450 (OEM). (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 40432 (213%)

Pixel Rate

The GeForce GT 450 (OEM) is quite a bit (more or less 28%) better at full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
GeForce GTX 650 Ti 2GB		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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
