Radeon HD 4350 vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which comes with clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 will be 340% faster than the Radeon HD 4350 overall, because of its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 27200 (340%)

Texel Rate

The Radeon R9 M375 should be much (about 783%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 36000 (783%)

Pixel Rate

The Radeon R9 M375 is quite a bit (more or less 606%) faster with regards to anti-aliasing than the Radeon HD 4350, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 13940 (606%)

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 data (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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