GeForce GTX 560 Ti 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 RAM is set to run at a speed of 800 MHz on this model. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Radeon HD 3650		5800 Mtexels/sec
	Difference: 46808 (807%)

Pixel Rate

The GeForce GTX 560 Ti should be quite a bit (approximately 807%) more effective at AA than the Radeon HD 3650, and also capable of handling higher screen resolutions better. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 23404 (807%)

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 MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, 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 most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
