GeForce GTX 460 1GB vs Radeon HD 3650

Intro

Compare all that to the Radeon HD 3650, which has core speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 memory. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3650		78 Watts
GeForce GTX 460 1GB		160 Watts
	Difference: 82 Watts (105%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB is 350% faster than the Radeon HD 3650 in general, because of its greater bandwidth. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 89600 (350%)

Texel Rate

The GeForce GTX 460 1GB should be quite a bit (more or less 552%) better at anisotropic filtering than the Radeon HD 3650. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 32000 (552%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 1GB is the winner, and very much so. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 18700 (645%)

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 max 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 card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
