Radeon HD 3650 256MB vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

The Radeon R9 M370X will be much (more or less 452%) more effective at anisotropic filtering than the Radeon HD 3650 256MB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 3650 256MB		5800 Mtexels/sec
	Difference: 26200 (452%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is a better choice, by a large margin. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 3650 256MB		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 data (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card 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 a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
