GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

Compare those specifications to the Radeon HD 3650, which comes with a GPU core clock speed of 725 MHz, and 1024 MB of GDDR4 memory running at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) SPUs, 8 TAUs, 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

Theoretically speaking, the GeForce GT 430 (OEM) will be 13% faster than the Radeon HD 3650 overall, due to its greater data rate. (explain)

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

Texel Rate

The GeForce GT 430 (OEM) will be a lot (about 93%) better at 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 lots of anti-aliasing is important to you, then the Radeon HD 3650 is superior to the GeForce GT 430 (OEM), not by a very large margin though. (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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
