Radeon R7 240 vs Radeon R9 M380

Intro

The Radeon R7 240 has core clock speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Compare those specs to the Radeon R9 M380, which comes with GPU core speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M380 should perform a lot faster than the Radeon R7 240 overall. (explain)

Radeon R9 M380 96000 MB/sec
Radeon R7 240 28800 MB/sec
Difference: 67200 (233%)

Texel Rate

The Radeon R9 M380 is much (more or less 174%) faster with regards to AF than the Radeon R7 240. (explain)

Radeon R9 M380 40000 Mtexels/sec
Radeon R7 240 14600 Mtexels/sec
Difference: 25400 (174%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M380 is superior to the Radeon R7 240, and very much so. (explain)

Radeon R9 M380 16000 Mpixels/sec
Radeon R7 240 5840 Mpixels/sec
Difference: 10160 (174%)

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 max amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
