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 set the core frequency at 725 MHz. The GDDR4 memory is set to run at a speed of 800 MHz on this card. It features 120(24x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce GTX 460 should perform a lot faster than the Radeon HD 3650 overall. (explain)

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

Texel Rate

The GeForce GTX 460 is quite a bit (approximately 552%) better at anisotropic 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 using lots of anti-aliasing is important to you, then the GeForce GTX 460 is a better choice, and very much so. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
