VS

GeForce GT 430 (OEM) vs Radeon HD 3650

Intro

The GeForce GT 430 (OEM) features core speeds of 700 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR3 memory. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

Compare those specs to the Radeon HD 3650, which uses a 55 nm design. AMD has clocked the core speed at 725 MHz. The GDDR4 memory runs at a speed of 800 MHz on this model. It features 120(24x5) SPUs as well as 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, the GeForce GT 430 (OEM) should perform a little bit faster than the Radeon HD 3650 overall. (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 (more or less 93%) more effective at 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

If running with high levels of AA is important to you, then the Radeon HD 3650 is the winner, but it probably won't make a huge difference. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
