Overclocking
I would like to preface this section with a few details about overclocking AMD. First up there are arbitrary limits imposed by the driver/software and therefore the memory was severely limited to 1860MHz or 14,880MHz effective. As always there will be tweaking and tuning options to go beyond this limitation whether it be modification to powerplay tables or other software workarounds, but we test it as most users would with their own PC. While some enthusiasts users may tune and tweak to the limit most will not overclock at all, so we made an attempt representative of what you can do out of the box with the easy to use tools publicly available. Such as the drivers tuning tab, along with tools such as precision or afterburner.
One thing to note when pushing AMD is that stability may not be present when overclocking so always test with a benchmark so you have a comparative score, otherwise your overclocking expeditions could net you worse than stock performance due to underlying instability.
First up is standard Time spy which we were able to push the default boost clock from its 1650 stock clock to 1775 netting us about an 8% gain. This GPU overclock along with the memory overclock net us a gain of approximately 10%+ going form a graphics score of 6856 to 7622. It is worth noting that with this fully stable overclock the RX 5600 XT is now nipping at the heels of the RX 5700.
Time Spy Extreme is a heavier loading 4K version of the DX12 benchmark. The same overclock levels we saw a graphics score of 3433 vs the stock speed score of 2964. This nets us a gain of approximately 14% which is quite huge. This result gives us a result that is not quite as close to the RX 5700 this time but still a huge jump and even combats the GTX 1080 at this level.
With that, I think its time we pull this one back into the stable and I start the arduous process of consolidating my thoughts.
