GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

Compare those specifications to the Radeon HD 3650, which comes with clock speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 RAM. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

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

In theory, the GeForce GT 430 (OEM) will be 13% quicker than the Radeon HD 3650 in general, because of its greater 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) should be a lot (about 93%) faster with regards to anisotropic filtering than the Radeon HD 3650. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 3650 is a better choice, though only just barely. (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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
