Overclocking + SAM vs. SAM compared to the original
Of course you have to benchmark all games once, so that you can see what scales as well as possible, how and where. I chose WQHD because it is probably the most common resolution for this card. The biggest increase was in Wolfenstein Youngblood and also in games like Metro Exodus and Watch Dogs Legion, where SAM alone was not yet able to do much, there are still various increases.
However, the restrictively monitored power limit and the only low addition possibilities make a more profitable OC almost impossible. AMD also limits the voltages, so that one can rely (in the month) only on what the Wattman offers. And it’s not much. Unfortunately.
Summary and conclusion
The new overclocking will probably be undervalued, because AMD has turned off the tap for now. If you can’t really use an extensive BIOS, nothing works from the outside, NVIDIA sends its regards. Of course, this is very much in line with RMA hopes, as none of the hobby overclockers can run amok in terms of voltage or power limit. The potential of the card is by no means exhausted, but one would simply not like to allow more.
Conversely, undervolting up to 900 mV and, with a good card, even up to 890 mV is definitely an option to make the RX 6800 even more economical and quiet. However, the test also showed that you should be careful with the clock rate increase, because the telemetry overpowers itself. And vice versa, the real savings roll is also a little more jittery. I would also like to contradict the one or the other test which is only based on the value for 1% low and thus implies a smooth image progression.
The evaluation of the variances on the previous page also shows that you can cheat yourself. But what always works and makes the picture much rounder is the combination of undervolting and a sensibly used frame limiter. Then, with a bit of luck, 72 Hz will even look better than the hibernation between 75 and 100.
