GeForce GTX 460 vs Radeon HD 3650

Intro

Compare all of that to the Radeon HD 3650, which makes use of a 55 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR4 RAM works at a frequency of 800 MHz on this model. It features 120(24x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Consumption (Max TDP)

Radeon HD 3650		78 Watts
GeForce GTX 460		150 Watts
	Difference: 72 Watts (92%)

Memory Bandwidth

The GeForce GTX 460 should theoretically perform a lot faster than the Radeon HD 3650 in general. (explain)

GeForce GTX 460		86400 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 60800 (238%)

Texel Rate

The GeForce GTX 460 will be quite a bit (approximately 552%) faster with regards to texture filtering than the Radeon HD 3650. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 is the winner, by far. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 13300 (459%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
