Radeon HD 4350 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which has GPU core speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be quite a bit superior to the Radeon HD 4350 overall. (explain)

Radeon R9 M375X		72000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 64000 (800%)

Texel Rate

The Radeon R9 M375X will be much (more or less 783%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 36000 (783%)

Pixel Rate

The Radeon R9 M375X should be much (approximately 606%) faster with regards to anti-aliasing than the Radeon HD 4350, and capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M375X		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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to get to the maximum fill rate.
