Radeon R9 M375 vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which comes with a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460, in theory, should perform much 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 a lot (approximately 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 is just a bit (approximately 7%) more effective at full screen anti-aliasing than the Radeon R9 M375, and also capable of handling higher resolutions better. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
