Radeon HD 4350 vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which comes with core speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M385X should in theory be quite a bit better than the Radeon HD 4350 overall. (explain)

Radeon R9 M385X		96000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 88000 (1100%)

Texel Rate

The Radeon R9 M385X is quite a bit (more or less 1239%) more effective at texture filtering than the Radeon HD 4350. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 57000 (1239%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M385X is the winner, by far. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 15300 (665%)

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 megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
