Radeon HD 3650 vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which features clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be a lot faster than the Radeon HD 3650 in general. (explain)

Radeon R9 M375X		72000 MB/sec
Radeon HD 3650		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon R9 M375X should be a lot (about 600%) better at anisotropic filtering than the Radeon HD 3650. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 3650		5800 Mtexels/sec
	Difference: 34800 (600%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375X is superior to the Radeon HD 3650, and very much so. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon HD 3650		2900 Mpixels/sec
	Difference: 13340 (460%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 processed in a second.

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