	Difference: 153600 (600%)

Texel Rate

The Radeon R7 370 2G is quite a bit (more or less 976%) better at anisotropic filtering than the Radeon HD 3650 512MB. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 56600 (976%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 370 2G is the winner, by a large margin. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 28300 (976%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
