GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

Compare all of that to the Radeon HD 3650, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR4 memory works at a speed of 800 MHz on this specific card. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Radeon HD 3650		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 (OEM) should be quite a bit (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

The Radeon HD 3650 should be a little bit (about 4%) better at full screen anti-aliasing than the GeForce GT 430 (OEM), and also able to handle higher resolutions while still performing well. (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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
