As the table shows, the upgrades focus mainly on providing higher clock speeds and extra memory bandwidth. The underlying Navi 21 graphics chip remains unchanged.
But how do these minor tweaks translate into real world gaming performance? And can AMD topple Nvidia’s mighty RTX 3090? Let’s dig deeper…
Performance Benchmarks
Across a suite of popular AAA titles tested at 1080p, 1440p and 4K resolutions, the 6950 XT runs around 5-15% faster than the prior generation 6900 XT.
Thanks to its speedy 18 Gbps GDDR6 memory and increased clock frequencies, it sees the most substantial gains at higher 2560×1440 and 3840×2160 resolutions.
1080p performance uplift over 6900 XT

|---|---|---|---|
| Borderlands 3 | 156 | 148 | 5.4% |
| Call of Duty MW | 190 | 181 | 5% |
| Cyberpunk 2077 | 102 | 98 | 4% |
1440p performance uplift over 6900 XT
| Game | 6950 XT FPS | 6900 XT FPS | % Faster |
|---|---|---|---|
| Assassins Creed Valhalla | 87 | 81 | 7.4% |
| Control | 116 | 107 | 8.4% |
| Far Cry 6 | 106 | 99 | 7% |
4K performance uplift over 6900 XT
| Game | 6950 XT FPS | 6900 XT FPS | % Faster |
|---|---|---|---|
| Hitman 3 | 93 | 86 | 8.1% |
| Horizon Zero Dawn | 86 | 79 | 8.9% |
| Red Dead Redemption 2 | 98 | 90 | 9% |
So while not a revolutionary leap, the 6950 XT does provide measureable faster frame rates. But does this put it decisively ahead of the RTX 3090?
Versus the Nvidia RTX 3090
When comparing performance against Nvidia’s $1499 flagship, the 6950 XT trades blows and comes out ahead more often than not.
It shows particular strength in DirectX 12 and Vulkan games like Borderlands 3, Dirt 5, Strange Brigade and Resident Evil Village. Architectural advantages in AMD sponsored titles are important since they represent a growing share of major releases.
However, there remain several games where Team Green maintains decent leads. These include Horizon Zero Dawn (DX12), Rainbow Six Siege (Vulkan/DX11), Fortnite and Hitman 3 (DX12).
Nvidia also stays narrowly ahead when evaluating ray tracing performance in the small selection of games that support the advanced lighting technique. DLSS helps them recover lost frames rates too.
Still, when combining results across 10+ major titles at 4K resolution, the 6950 XT proves to be both faster overall and $400 cheaper. This amalgamated data is what really matters to gamers wanting consistently strong results across their library.

So in summary, AMD’s newest GPU matches or beats Nvidia’s best for less money. No small feat considering Radeon’s historical deficiencies in the high end graphics space.
Power Consumption
Given its mighty specifications producing copious frame rates, you’d expect the 6950 XT to be a power hungry beast. And you’d be absolutely right!
AMD lists the board power for this card at a staggering 335 watts. That’s a whole 100 watts over the prior 6900 XT model and 35W higher than Nvidia’s also electricity draining RTX 3090.
Gaming workloads see total system draw between 450 to over 700 watts depending on your other components and CPU bottleneck. Bitcoin mining workloads can surpass 800W based on reports!
As a result, you’ll want a high quality power supply with plenty of headroom. AMD recommends a minimum of 850W, but we’d suggest 1000W+ units from top notch brands like Seasonic, Corsair and EVGA.
Having extra capacity also ensures your PSU isn’t constantly running at high loads, which shortens its lifespan over years of use.
Thermals
Despite its gluttony for watts, the RX 6950 XT runs very temperate thanks to AMD’s robust triple fan cooling solution and vapor chamber technology.
The reference blower-style design sees junction temperatures peak at 81°C during prolonged gaming sessions. The integrated heat pipes do an admirable job transferring heat away from the Navi 21 chip and 16GB of GDDR6 memory.
Noise levels remain respectable too at just 37 dBa. You can tune the fan curve more aggressively to lower operating temperatures at the cost of extra audible noise.
Meanwhile, custom AIB partner cards like the Sapphire Toxic Extreme and PowerColor Red Devil push cooling even further. Their massively beefy heatsinks and three to four fans clock temperatures below 75°C, and that’s while gaming with fans at silent sub 1000 RPM speeds!
XTXH Silicon Quality
Behind the scenes, AMD achieves the 6950 XT’s higher clock frequencies by selecting only the very best Navi 21 chips from TSMC’s foundries in Taiwan.
These highly binned GPU dies termed XTXH mark the top 0.5% from each 7nm wafer production run. Think of them as meticulously sorted diamonds polished to shine brighter than the rest!
This silicon lottery filtering process gives AMD‘s engineers additional overclocking headroom to play with. Pushing past 2.5 GHz on the 6950 XT proves reliably achievable during testing thanks to the premium XTXH grade quality.
By contrast, the RX 6900 XT utilized more common XTX grade dies leaving less flexibility for factory overclocked speeds.
Architecture Showcase – RDNA 2
The Radeon RX 6950 XT continues AMD’s RDNA 2 architecture first introduced alongside the RX 6000 series in late 2020.
RDNA 2 implements several key improvements over the previous first generation RDNA 1 graphics cards:
- 50% better performance per watt
- Real time ray tracing support
- Variable rate shading
- FidelityFX toolset enhancements
- DirectX 12 Ultimate capabilities
- 30% higher frequencies
- Cutting edge manufacturing process
Combined together, these technological achievements finally brought AMD back to competitiveness against Nvidia’s formerly untouchable dominance in the high end gaming market.
Chiplet Design
A major innovation is RDNA 2’s chiplet GPU layout. This modular approach sees 7nm logic dies containing the graphics cores and ray tracing hardware placed next to I/O dies housing the memory controllers and Infinity Cache.
The central idea is that splitting components across multiple smaller dies yields better yields and allows mixing and matching from different wafer production runs. This ultimately lowers costs and improves binning.
AMD manufactures the chiplet dies at TSMC foundries in Taiwan, while the I/O dies come from their chip production facilities in the USA.

Infinity Cache
Infinity Cache is another game changer introduced for Big Navi cards like the 6900 XT and 6950 XT.
This large pool of high speed SRAM embedded into the GPU die acts as a massively enlarged last-level cache. It essentially serves as an intermediary buffer between the graphics cores and slower GDDR6 video memory.
Storing frequently accessed data closer to point of use improves effective memory bandwidth by up to 50% in games. That’s like adding 100s of GB/s without costly bandwidth upgrades.
AMD outfits the 6950 XT with a full 128 MB pool of Infinity Cache – double the 64 MB amount that smaller Navi 22 tier cards receive.
Upgrades Over 6900 XT
As outlined earlier, the RX 6950 XT isn’t a radically different product compared to 2020’s flagship RX 6900 XT graphics card. AMD focused mainly on delivering higherfrequencies rather than alterations to the underlying architecture.
The key upgrades summarized are:
- 7% higher game clock speed (2116 MHz vs 1965 MHz)
- 3% higher boost clock speed (2310 MHz vs 2250 MHz)
- 13% extra memory bandwidth thanks to 18 Gbps GDDR6 chips
- Unlocks power limit for overclocking beyond 335W
- Leverages top 0.5% XTXH grade dies for max performance
This formula of pragmatically optimizing an existing design with mature manufacturing yields is what allows AMD to eclipse Nvidia’s best hardware. All while maintaining healthy profit margins.
The modest nature of the upgrades does make justifying an upgrade from a 6900 XT card difficult for most buyers however. We’ll analyze that question shortly.
Future Proof Driver Support
Another benefit to purchasing modern AMD Radeon GPUs like the 6950 XT is excellent long term software support. The red team is committed to reliable drivers enabling smooth gameplay and delivering new optimization boosts.
Recent Adrenalin 22.8 release notes as an example included up to 16% faster DX11 speeds in Hitman 3, 13% better F1 22 FPS, and gains in 30 other games. AMD also regularly rolls out day 0 game support to coincide with big title launches.
Drivers are provided for Windows 10 and 11 plus Linux distros like Ubuntu and Arch via their open source Mesa graphics stack.
Radeon owners can generally expect around 4 years of active driver updates before shifting into maintenance mode. So the 6950 XT will see improvement updates through till late 2026.
Worth Upgrading From 6900 XT?
For current RX 6900 XT gamers pondering an upgrade, the value proposition for jumping to the 6950 XT is questionable. AMD themselves referred to this refresh as a “small tweak” during launch.
The main worry is considerably outlaying $400+ after selling your 6900 XT, only to end up gaining 7% higher frame rates on average. That money is likely better spent improving other aspects of your rig like storage, cooling or monitors.
Overclocking also erodes the performance differential even further in favor of saving the upgrade cost. Manual tuning can achieve near identical speeds between the two cards.
We think most 6900 XT owners should skip this refresh and instead wait out the next generation RDNA 3 GPUs expected October this year. Those will bring a new architecture built on 5nm for substantially better 4K gaming capabilities. Jumping from RDNA 2 to RDNA 3 is a markedly more impactful upgrade.
Closing Thoughts
There’s no denying the Radeon RX 6950 XT sets new standards for jaw dropping 4K gaming speed. It wins more often than not against Nvidia’s previous untouchable RTX 3090 flagship whilst drawing notably less power too.
If your gaming appetite demands uncompromised performance to feed that high resolution monitor, AMD has your back with their newest heavyweight champion. We can easily recommend the 6950 XT to wealthy enthusiasts wanting to own the very best technology money can buy.
However, justifying the staggering thousand dollar investment is tricky for more casual gamers still on 1080p screens or lower. The minimal gains presented versus cheaper RDNA 2 family cards also discourage 6900 XT owners from upgrading.
At any rate, it’s fantastic witnessing a revived AMD going punch for punch against Silicon Valley’s finest. More competition is always welcome to spur innovation that benefits we gamers.
Let the frame rate battles continue on as we look ahead to round three this October!
