GeForce 930M vs Radeon HD 3650

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 3650 will be 78% quicker than the GeForce 930M overall, because of its greater bandwidth. (explain)

Radeon HD 3650		25600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 930M is a lot (approximately 284%) more effective at AF than the Radeon HD 3650. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 16472 (284%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 930M is superior to the Radeon HD 3650, and very much so. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 4524 (156%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
