Radeon R9 M375 vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which features core clock speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 460 should perform quite a bit faster than the Radeon R9 M375 overall. (explain)

Radeon RX 460		112000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 76800 (218%)

Texel Rate

The Radeon RX 460 should be much (about 50%) faster with regards to texture filtering than the Radeon R9 M375. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 20440 (50%)

Pixel Rate

The Radeon RX 460 should be a little bit (approximately 7%) more effective at full screen anti-aliasing than the Radeon R9 M375, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 1200 (7%)

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 max amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
