GeForce GTX 460 SE vs Radeon HD 5450

Intro

Compare all of that to the Radeon HD 5450, which has core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth

In theory, the GeForce GTX 460 SE should be a lot faster than the Radeon HD 5450 in general. (explain)

GeForce GTX 460 SE		108800 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 96000 (750%)

Texel Rate

The GeForce GTX 460 SE is much (approximately 500%) more effective at texture filtering than the Radeon HD 5450. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 26000 (500%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 SE is a better choice, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 18200 (700%)

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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
