GeForce GT 450 (OEM) vs GeForce GTX 295

Intro

Compare all of that to the GeForce GTX 295, which features core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the GeForce GTX 295 should in theory be a lot superior to 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 (more or less 386%) more effective 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 lots of anti-aliasing 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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be applied in one second. This is calculated by multiplying the total texture units of the card by the core 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 most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
