GeForce 930M vs Radeon HD 3650 512MB

Intro

Compare all that to the Radeon HD 3650 512MB, which uses a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR3 memory is set to run at a speed of 800 MHz on this particular model. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 3650 512MB should theoretically be quite a bit better than the GeForce 930M overall. (explain)

Radeon HD 3650 512MB		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 512MB. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 16472 (284%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 930M is a better choice, by a large margin. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 3650 512MB		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 megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
