Radeon RX 6800 XT Overclocked to 2.80 GHz on LN2, Crushes 3DMark Fire Strike Record
One of the secret sauces of AMD's new "Big Navi" Radeon RX 6800 series GPUs is the ability for the GPU to sustain high engine clock speeds, with the company leveraging boost frequencies above 2.00 GHz in certain scenarios. It was only a matter of time before professional overclockers got their hands on an RX 6800 XT, and paired it with an LN2 evaporator. TecLab_Takukou is the new king of the 3DMark Fire Strike leaderboard thanks to their skills in running an RX 6800 XT at insane 2.80 GHz engine clocks. Takukou overclocked the RX 6800 XT to 2.80 GHz core, and 2150 MHz (17.2 Gbps) memory. This particular configuration yielded a Fire Strike score of 48890 points.
In a separate feat, with the RX 6800 XT running at 2.75 GHz, Takukou chased down the HWBot 3DMark Fire Strike leaderboard, with 49456 points. For both the 2.80 GHz and 2.75 GHz feats, the rest of the system included an LN2-cooled AMD Ryzen 9 5950X processor running at 5.60 GHz all-core, 32 GB of DDR4-3800 memory, and an MSI MEG X570 GODLIKE motherboard. From the looks of it, Takukou is using a reference-design RX 6800 XT board, so we can only hope what else can be accomplished from custom-design RX 6800 XT boards, such as the Sapphire NITRO+, PowerColor Red Devil, or ASUS ROG Strix O16G. Takukou leads the 3DMark Fire Strike leaderboard, followed by another RX 6800 XT-powered close-second, Lucky_n00b (47932 points, 2.65 GHz engine clock on air). Safedisc is third (47725 points, RTX 3090 @ 2.38 GHz).

...when thinking that this is "only" 6800 XT, the 6900 XT can be even more interesting one.And I was like mind = blown when I broke the magical 1GHz barrier on HD 4890 11 years ago.

The clockspeed is impressive, but the power consumption will be exponentially more impressive. :oops:
You can push lots of IPC; but that IPC is even better to use when the clocks are as high as possible.
Consider it as a highway; one highway has 8 lanes with a maximum speed of 80kmph. The other highway has 4 lanes but a maximum speed of 160. Now which one is actually faster in certain workloads?
2.8Ghz is pretty impressive. We're one to two generations away from reaching the 3GHz boost range.
well, at least until the power limit on the reference cards can be modded, that is.

You'll get shit like this.
Either way, AIBs cards are cheaper for a reason and it doesn't mean they use quality components. They do but mostly they use bare minimum to make it work.
if you are not familiar with the +15% limit here, that's what the reference tops at right now.
to be clear: I never said higher power limit equals to good quality.
now, not all AIB cards are cheaper than reference. e.g. asus ROG strix, sapphire nitro+, power color devil - at least in my country.
of course not the el cheapo one like tuf or pulse :roll:
this thing is trashing LN2 3090's. really impressive.
On the memory.QFT! Haha
BiG NAVI: Don't underestimate my powers
Ampere: Don't try it
Result: BiG NAVI's frame rate was sliced in half with ray tracing.
;)
