GeForce GT 450 (OEM) vs Radeon HD 3470 512MB

Intro

Compare all of that to the Radeon HD 3470 512MB, which has a GPU core clock speed of 800 MHz, and 512 MB of GDDR3 RAM set to run at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 450 (OEM) should be 216% faster than the Radeon HD 3470 512MB overall, due to its greater data rate. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 65600 (216%)

Texel Rate

The GeForce GT 450 (OEM) is much (more or less 493%) more effective at anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 15760 (493%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon HD 3470 512MB, and very much so. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 15760 (493%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
