Radeon R9 380 4G vs Radeon R9 M380

Intro

The Radeon R9 380 4G makes use of a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 memory runs at a frequency of 1425 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

Compare all of that to the Radeon R9 M380, which features a core clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 380 4G will be 90% quicker than the Radeon R9 M380 in general, because of its higher bandwidth. (explain)

Radeon R9 380 4G 182400 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 86400 (90%)

Texel Rate

The Radeon R9 380 4G will be quite a bit (approximately 172%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

Radeon R9 380 4G 108640 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 68640 (172%)

Pixel Rate

The Radeon R9 380 4G should be quite a bit (about 94%) faster with regards to AA than the Radeon R9 M380, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 380 4G 31040 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 15040 (94%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount 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 is also dependant on many 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.
