Radeon R9 380X vs Radeon R9 M375

Intro

Compare all that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory works at a speed of 1100 MHz on this specific model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 380X will be 418% faster than the Radeon R9 M375 in general, due to its greater data rate. (explain)

Radeon R9 380X		182400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 147200 (418%)

Texel Rate

The Radeon R9 380X should be a lot (approximately 206%) better at AF than the Radeon R9 M375. (explain)

Radeon R9 380X		124160 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 83560 (206%)

Pixel Rate

The Radeon R9 380X is a lot (about 91%) better at FSAA than the Radeon R9 M375, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 380X		31040 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 14800 (91%)

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 MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
