GeForce GT 450 (OEM) vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which uses a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 RAM works at a speed of 999 MHz on this particular card. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.

GeForce GT 450 (OEM)		106 Watts
GeForce GTX 295		289 Watts
	Difference: 183 Watts (173%)

Memory Bandwidth

In theory, the GeForce GTX 295 should perform a lot faster than the GeForce GT 450 (OEM) overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 127776 (133%)

Texel Rate

The GeForce GTX 295 should be much (approximately 386%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 73200 (386%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 295 is superior to the GeForce GT 450 (OEM), and very much so. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 13296 (70%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
