About this deal

For this test, we measure power consumption of only the graphics card via the PCI-Express power connector(s) and PCI-Express bus slot. A Keithley Integra 2700 digital multimeter with 6.5-digit resolution is used for all measurements. Again, these values only reflect the card's power consumption as measured at its DC inputs, not that of the whole system. Gamers want highly responsive gameplay and the best visual fidelity. Radeon™ Anti-Lag4 – significantly decreases input-to-display response times and offers a competitive edge in gameplay. The AMD FidelityFX5 open-source toolkit for game developers provides a collection of lighting, shadow and reflection effects that make it easier for developers to add high-quality post-process effects that make games look beautiful, while offering the optimal balance of visual fidelity and performance. Our final paper test introduces something new to the table in Raytracing, now, games using Raytracing are thin on the ground and benchmarks for RT are even scarcer. Add to that the conundrum that everything is optimised and built for Nvidias RT currently and we have a real problem. In the end I settled on what I consider to be the fairest possible RT benchmark to run at this time as it is hardware agnostic and will run on both AMD and Nvidia hardware; Cryteks Neon Noir. It’s not ideal still, but it is the best we currently have really for the time being in a non-biased RT benchmark.

We know the shuffle here, time to tear down the card and see what we have underneath that colossal epic sized heatsink assembly. As always this phase is done last after benchmarking and temperature measurements so results are as representative as possible for what you will get out of the box. We used MSI’s Afterburner to set all video cards’ power and temperature limits to maximum. AMD Adrenalin Control Center Settings Here are SPECviewperf 2020 GPU reference and Red Devil RX 6800 XT benchmarks summarized in a chart together with five other cards. Sound levels have been measured with a digital sound meter here, if you are a gamer who uses headphones you could likely turn those fans almost right up and not hear anything intrusive as you can see here noise levels with the 6800XT Red Devil were not all that intrusive, 60% is probably going to be the practical limit for most people who don’t game with headphones.

Drivers and Software

Time Spy is a DirectX 12 benchmark test for Windows 10 gaming PCs. Time Spy is one of the first DirectX 12 apps to be built the right way from the ground up to fully realize the performance gains that the new API offers. With its pure DirectX 12 engine, which supports new API features like asynchronous compute, explicit multi-adapter, and multi-threading, Time Spy is the ideal test for benchmarking the latest graphics cards. (UL). Improving power efficiency of the GPU architecture has been the key to success for current-generation GPUs. It is also the foundation for low noise levels because any power consumed will turn into heat that has to be moved away from the GPU by its thermal solution. Lower heat output also helps improve cost because smaller, cheaper thermal solutions can be used. The RX 6800 XT is a fast GPGPU card and it compares favorably with the Ampere cards being weaker in some areas and stronger in others. So let’s look at Sandra 2020 next. SiSoft Sandra 2020 With the above in mind, we ran Sandra’s intensive GPGPU benchmarks and charted the results summarizing them. Engine: Unreal Engine 4. We test using the Ultra preset, with Best Animation Quality (instead of Auto), DX12 API.

For Radeon gamers, the reference RX 6800 XT is a very decent alternative to GeForce Ampere cards for the vast majority of modern PC games that use rasterization. The RX 6800 XT offers 16GB of GDDR6 to the 10GB of GDDR6X that the RTX 3080s are equipped with. Last but not least we have Watch Dogs: Legion. In this title, the Red Devil averages 55FPS at 4K, which works out as a 4% lead over the reference card. Compared to the RTX 3080 Founders Edition, it is 5% slower. Red Dead Redemption 2 sees the Red Devil once more outpacing the reference RX 6800 XT by a 4% margin at 4K, though this is a difference of just 2FPS at this resolution.I really can’t say there is anything surprising here the 5700XT looks decidedly midrange (1440p60) while the 6800XT displays again the superiority and evolutionary gains it has. The OpenGL results are also not surprising to me AMD have been terrible at OpenGL for years now, or rather I should say AMDs Windows driver\team has been terrible at OpenGL performance for years. Whatever is going on here they need to take pointers from the Mesa Coders] that quite frankly, rather badly show up whoever is doing the Windows OpenGL portion of the driver. Moving to the results despite the overall reasonably good temperatures with default values the junction temperature of 106c is a bit disconcerting; it’s not something to get alarmed by though.
