Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X, in theory, should be much faster than the Radeon HD 3650 512MB overall. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 3650 512MB		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M370X should be a lot (more or less 452%) better at AF than the Radeon HD 3650 512MB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 26200 (452%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M370X is superior to the Radeon HD 3650 512MB, by a large margin. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 9900 (341%)

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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
