Radeon HD 3650 256MB vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X should in theory perform quite a bit faster than the Radeon HD 3650 256MB in general. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 3650 256MB		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M370X will be quite a bit (about 452%) more effective at texture 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 using lots of anti-aliasing 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 max amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be applied per second. This is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
