Radeon R7 M260 vs Radeon R9 M380

Intro

The Radeon R7 M260 makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this particular model. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare those specs to the Radeon R9 M380, which features a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M380 should be quite a bit faster than the Radeon R7 M260 in general. (explain)

Radeon R9 M380 96000 MB/sec
Radeon R7 M260 16000 MB/sec
Difference: 80000 (500%)

Texel Rate

The Radeon R9 M380 is a lot (approximately 133%) better at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R9 M380 40000 Mtexels/sec
Radeon R7 M260 17160 Mtexels/sec
Difference: 22840 (133%)

Pixel Rate

The Radeon R9 M380 is quite a bit (about 180%) faster with regards to full screen anti-aliasing than the Radeon R7 M260, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon R9 M380 16000 Mpixels/sec
Radeon R7 M260 5720 Mpixels/sec
Difference: 10280 (180%)

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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
