First off its still early days in the PC gaming HDR world. At the same time reading this I didn't expect they was a performance pen for using HDR. AMD seems to be doing a better job at this moment.
Surprising results do not change the conclusion
When planning the article, the editors actually assumed that the results would be boring - because the same - and the expectations would only be confirmed. It was then but much more exciting than expected. Because in terms of performance, it seldom matters whether HDR is used or not. Some games lose quite a bit of performance depending on the graphics card.
Depending on the game, there is a different power loss
With HDR must be differentiated at present between a AMD and a Nvidia graphics card. Because the used in the test Radeon RX Vega 64 loses in most titles actually no performance when switching from SDR to HDR. The worst case is Destiny 2 with less than ten percent less FPS and Far Cry 5 with a five percent loss. On average, the use of HDR on the Radeon with two percent loss is not noticeable.
On a Nvidia graphics card, the power loss is currently much higher. The GeForce GTX 1080 loses an average of 10 percent of images per second with "High Dynamic Range", while in Destiny 2 it is even 20 percent. Thus, the loss of speed on a Nvidia graphics card unlike on an AMD accelerator is quite noticeable. And it also shifts the performance structure: Because with SDR there is a tie between the two graphics cards, with HDR but AMD is the front.
The reason for the behavior is unclear
Why Nvidia GPUs have to contend with greater losses than the AMD graphics cards, is currently unclear - even Nvidia could not call the editors any reason. Nevertheless, the recommendation is to use HDR with a corresponding monitor. There are not many games that support HDR yet. However, most of them do look much better. The difference is much bigger than one or two higher levels of detail, so you can reduce them and make the game look more beautiful. However, you may need to reduce more details on a GeForce than on a Radeon.
