GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 (OEM)		60 Watts
Radeon HD 3650		78 Watts
	Difference: 18 Watts (30%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 430 (OEM) will be 13% quicker than the Radeon HD 3650 in general, because of its higher bandwidth. (explain)

GeForce GT 430 (OEM)		28800 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 (OEM) is a lot (approximately 93%) faster with regards to AF than the Radeon HD 3650. (explain)

GeForce GT 430 (OEM)		11200 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 5400 (93%)

Pixel Rate

The Radeon HD 3650 is a bit (about 4%) more effective at anti-aliasing than the GeForce GT 430 (OEM), and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 3650		2900 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 100 (4%)

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 information (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
