GeForce GT 450 (OEM) vs GeForce GTX 460 (OEM)

Intro

Compare that to the GeForce GTX 460 (OEM), which makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 (OEM) is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 1840 (10%)

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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount 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 applied in a second.

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