XFX R9 380 4G Double Dissipation Black Edition (R9-380P-4DB5)

Test Rig & Benchmarks

The OS we use is Windows 10 Pro 64bit with all patches and updates applied. We also use the latest drivers available for the motherboard and any devices attached to the computer. We do not disable background tasks or tweak the OS or system in any way. We turn off drive indexing and daily defragging. We also turn off Prefetch and Superfetch. This is not an attempt to produce bigger benchmark numbers. Drive indexing and defragging can interfere with testing and produce confusing numbers. If a test were to be run while a drive was being indexed or defragged, and then the same test was later run when these processes were off, the two results would be contradictory and erroneous. As we cannot control when defragging and indexing occur precisely enough to guarantee that they won’t interfere with testing, we opt to disable the features entirely.

Prefetch tries to predict what users will load the next time they boot the machine by caching the relevant files and storing them for later use. We want to learn how the program runs without any of the files being cached, and we disable it so that each test run we do not have to clear pre-fetch to get accurate numbers. Lastly we disable Superfetch. Superfetch loads often-used programs into the memory. It is one of the reasons that Windows Vista occupies so much memory. Vista fills the memory in an attempt to predict what users will load. Having one test run with files cached, and another test run with the files un-cached would result in inaccurate numbers. Again, since we can’t control its timings so precisely, it we turn it off. Because these four features can potentially interfere with benchmarking, and are out of our control, we disable them. We do not disable anything else.

We ran each test a total of 3 times, and reported the average score from all three scores. Benchmark screenshots are of the median result. Anomalous results were discounted and the benchmarks were rerun.

Here’s our Stock GPU-Z shot of the XFX R9 380 4G DD Black Edition and it shows the correct clock speed of 1030 with the memory at 1450 real 5800 Effective and as you can see everything is as it should be according to the website specification and the information on the box.


The orange Bar on Cinebench is the XFX R9 380 4G DD at stock speed. and we got 163.62 FPS now glance at the Brown bar which is our overclocked speed and we hit 170.02 FPS.


Here’s our best Core OC of 1149 MHz and we could go as high as 1161 but it’s best to back down a few MHz for your 24 / 7 OC than to run out on the ragged edge.
