AMD Radeon RX 6800 XT & Radeon RX 6800 16 GB Graphics Cards Review – Here’s Big Navi!
Testing Smart Access Memory On The AMD Radeon RX 6800 XT / RX 6800
Smart Access Memory was one of the bigger features that AMD brought out on stage, but during testing, it was clear that only a handful of motherboards supported the feature at the time but full support would be coming by launch. Interestingly enough our motherboard, the ASUS TUF Gaming X570 Plus-WiFi, had the needed options available in the UEFI to enable it. I reached out several times asking for clarification if my board supported and never got a definitive answer. So I tested it on my own.
Looks like it worked for the most part which is why it is relegated to its own page for direct comparison with it on and off in an unofficially supported manner. Because we were able to see some benefits from it we did include it in our DXR testing to try and help them out a bit since we also tested DLSS on for the RTX cards.
With more universal support for PCIe BAR Resizing coming in the future this one will be getting revisited sooner rather than later.
Forza Horizon 4
Forza Horizon 4 carries on the open-world racing tradition of the Horizon series. The latest DX12 powered entry is beautifully crafted and amazingly well executed and is a great showcase of DX12 games. We use the benchmark run while having all of the settings set to non-dynamic with an uncapped framerate to gather these results.
Shadow of the Tomb Raider
Shadow of the Tomb Raider, unlike its predecessor, does a good job putting DX12 to use and results in higher performance than the DX11 counterpart in this title and because of that, we test this title in DX12. I do use the second segment of the benchmark run to gather these numbers as it is more indicative of in-game scenarios where the foliage is heavy.
Rainbow 6 Siege
Rainbow 6 Siege has maintained a massive following since its launch and it consistently in Steams Top Ten highest player count game. In a title where the higher the framerate the better in a tactical yet fast-paced competitive landscape is essential, we include this title despite its ludicrously high framerates. We use the Vulkan Ultra preset with the High Defenition Texture Pack as well and gather our results from the built-in benchmarking tool.
DOOM Eternal brings hell to earth with the Vulkan powered idTech 7. We test this game using the Ultra Nightmare Preset and follow our in-game benchmarking to stay as consistent as possible.
Watchdogs Legions sees a return of the Disrupt Engine they've been using since the early days with the original Watchdogs but this time it has been updated to next generation feature support. Dropping DX11 for DX12 we see much better utilization than in the past. Being one of the recent top sellers it earned a place in our test suite.
Call of Duty Modern Warfare (2019)
Call of Duty Modern Warfare is back and this time on a new engine running DX12 to allow for some sick DXR Ray Traced Shadows, those results are in the RT section We tested in the 'Fog of War' mission. At 4K we set the settings all to High.
Horizon Zero Dawn
Horizon Zero Dawn is one of the two major PS4 exclusives that rocked their way onto the PC scene with massive acceptance and sales. Horizon Zero Dawn is powered by the Decima Engine and has been ported to DX12. We used the in-game benchmark to account for performance.
Borderlands 3 has made its way into the test lineup thanks to strong demand by gamers and simply delivering MORE Borderlands. This game is rather intensive after the Medium preset but since we're testing the 'Ultimate UW 1440p' card, High it is. We tested using the built-in benchmark utility
Total War Saga: Troy
Total War Saga: Troy is powered by their TW Engine 3 (Total War Engine 3) and in this iteration, they have stuck to a strictly DX11 release. We tested the game using the built-in benchmark using the Dynasty model that represents a battle with many soldiers interacting at once and is more representative of normal gameplay.
