GeForce GT 450 (OEM) vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which comes with GPU core speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also features 768 Stream Processors, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 4 Watts (4%)

Memory Bandwidth

The GeForce GT 450 (OEM), in theory, should perform just a bit faster than the GeForce GTX 650 Ti in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
GeForce GTX 650 Ti		86400 MB/sec
	Difference: 9600 (11%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (more or less 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

If running with a high screen resolution is important to you, then the GeForce GT 450 (OEM) is the winner, and very much so. (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 past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
