GeForce GT 430 1GB vs Radeon HD 3650

Intro

Compare those specifications to the Radeon HD 3650, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR4 RAM works at a frequency of 800 MHz on this particular card. 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 1GB		60 Watts
Radeon HD 3650		78 Watts
	Difference: 18 Watts (30%)

Memory Bandwidth

The GeForce GT 430 1GB should in theory perform a little bit faster than the Radeon HD 3650 overall. (explain)

GeForce GT 430 1GB		28800 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 3200 (13%)

Texel Rate

The GeForce GT 430 1GB should be quite a bit (about 93%) faster with regards to texture filtering than the Radeon HD 3650. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 5400 (93%)

Pixel Rate

The Radeon HD 3650 is just a bit (approximately 4%) more effective at FSAA than the GeForce GT 430 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 3650		2900 Mpixels/sec
GeForce GT 430 1GB		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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
