GeForce GT 450 (OEM) 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 runs at a speed of 800 MHz on this model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Radeon HD 3650		5800 Mtexels/sec
	Difference: 13160 (227%)

Pixel Rate

The GeForce GT 450 (OEM) is a lot (more or less 554%) more effective at AA than the Radeon HD 3650, and able to handle higher resolutions more effectively. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 16060 (554%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
