The AMD Radeon VII Review: An Unexpected Shot At The High-End

Benchmarking Testbed Setup

To preface, because of the SMU changes mentioned earlier, no third party utilities can read Radeon VII data, though patches are expected shortly. AIB partner tools such as MSI Afterburner should presumably launch with support. Otherwise, Radeon Wattman was the only monitoring tool possible, except we observed that the performance metric log recording and overlay sometimes caused issues with games.

On that note, a large factor in this review was the instability of press drivers. Known issues include being unable to downclock HBM2 on the Radeon VII, which AMD clarified was a bug introduced in Adrenalin 2019 19.2.1, or system crashes when the Wattman voltage curve is set to a single min/max point. There are also issues with DX11 game crashes, which we also ran into early on, that AMD is also looking at.

For these reasons, we won't have Radeon VII clockspeed or overclocking data for this review. To put simply, these types of issues are mildly concerning; while Vega 20 is new to gamers, it is not new to drivers, and if Radeon VII was indeed always in the plan, then game stability should have been a priority. Despite being a bit of a prosumer card, the Radeon VII is still the new flagship gaming card. There's no indication that these are more than simply teething issues, but it does seem to lend a little credence to the idea that Radeon VII was launched as soon as feasibly possible.

Thanks to Corsair, we were able to get a replacement for our AX860i. While the plan was to utilize Corsair Link as an additional datapoint for power consumption, for the reasons mentioned above it was not feasible for this time. On that note, power consumption figures will differ for earlier GPU 2018 Bench data.

In the same vein, for Ashes, GTA V, F1 2018, and Shadow of War, we've updated some of the benchmark automation and data processing steps, so results may vary at the 1080p mark compared to previous GPU 2018 data.
