Radeon R9 M375 vs Radeon RX 460

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460, in theory, should perform a lot faster than the Radeon R9 M375 in general. (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 (more or less 50%) better at AF 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 (more or less 7%) faster with regards to AA than the Radeon R9 M375, and also should be capable of handling higher resolutions without slowing down too much. (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 maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
