The Radeon RX 6900 XT ships with a beefy triple-fan cooling array that keeps its Navi GPU running around 60 to 65 degree temperatures under typical gaming loads. Clock stretches are also satisfied thanks 100% of the time enabling full utilization of its 2.25 GHz boost specification. AMD has the upper hand when it comes to power efficiency – at 300W TDP for the total board power, it sips 20 to 30W less than NVIDIA‘s offering.
On the GeForce side, our RTX 3080 Ti test model from ASUS features their capable triple Axial-tech fan configuration and max-contact heat pipes. Though heavier at 350W TDP, the GPU touched temperatures of just 63 degree at peak. The card maintained its rated 1.67 GHz clock boost in every test thanks to NVIDIA‘s GPU Boost algorithm.
Both cards may see temperatures rise further during warmer summers. I suggest ramping fan speeds up a bit to help counter that. Observe that the 3080 Ti runs slightly hotter balancing its higher core counts and clock frequencies. Still, sustained clocks always satisfied specifications promoting optimal gaming experiences. The beefy coolers give enough thermal headroom there!
Ray Tracing and Upscaling Capabilities
Ray tracing has been a revolutionary advancement empowering photorealistic real-time lighting and reflections in supported games. NVIDIA GeForce RTX cards starting from the previous Turing generation pack dedicated hardware units to accelerate ray tracing. AMD joined the party integrating ray accelerators with RDNA 2 GPUs that help enhance ray tracing potential on their Radeon line.
Between the two flagships, RTX 3080 Ti has an advantage with its 128 dedicated RT cores versus just 80 on the 6900 XT. In several ray traced titles tested, the 3080 Ti maintained 15 to 20% higher average FPS over AMD with DXR effects enabled. That allows more fluid gameplay given demanding ray calculations.
DLSS support on Team Green‘s cards provides up to 2X FPS speed boost in select titles by rendering at lower resolutions before upscaling through dedicated AI Tensor cores. AMD is fighting back with their FidelityFX Super Resolution technology available in several recent games. But quality and scaling factors are not yet fully competitive against NVIDIA DLSS‘ second-gen 2.0 implementation.
Over time, expect the differences to narrow down as AMD fine tunes its upscaling tech. But as of today, GeForce RTX series continues retaining an edge for the high-fidelity gaming experiences aided by its suite of AI enhanced visual technologies. Radeons handle classic rasterization and compute extremely well in line with team green too!
Cryptocurrency Mining Capabilities
Cryptominers have developed an insatiable appetite for high-end gaming graphics cards. Their immense parallel processing abilities translate to strong hashrates for tokens like Ethereum. Before its recent merger to proof-of-stake, efficient Ethereum mining was a very profitable endeavor.
RDNA 2 architecture proves extremely capable churning out 62+ MH/s Ethereum mining rates. AMD‘s cards have stayed resistant against hash throttling through driver or firmware tricks. In turn, cryptocurrency miners gobbled up 6900 XT units thanks to stellar mining efficiency. The card only needs to draw around 145W from the wall when mining keeping operational costs down.
By comparison, GeForce RTX 3080 Ti achieves just 58 MH/s in Ethereum thanks to NVIDIA‘s anti-mining algorithm that slashes rates for sustained workloads. The sensor-equipped Founders Edition throttles down aggressively when subjected to continual mining usage, sometimes below 100W! Without sufficient airflow, clock drops can reduce Ethereum potential under 40 MH/s too rendering mining unfeasible.
So for anyone still interested, AMD Radeon cards spearheaded by the 6900 XT easily emerge as the most profitable options for mining purposes. Obtaining one for MSRP continues to prove difficult though!
