“We are surprised that the RTX 3080 is able to give a superior VR experience at more demanding settings than the RTX 2080Ti”
Why is he surprised - it’s a far more powerful card!! Am I missing something?

Have you seen the video from der8auer that DrWilken posted above? He first benchmarked a card with 6 big capacitors (slightly unstable at highest standard boost clock), then removed two (stability decreased even further from 1h to 1 minute until crash), then replaced them with 20 small ones (stability increased over the initial level - no crash measured). Doesn’t seem to help a big deal regarding overclocking potential but seems to have a measurable impact for the same chip. And Evga have also tested and confirmed it and changed their production to using a combination of capacitors. So not really irrelevant, right?

Anyone received theirs yet? I don’t receive mine until Friday.
According to Golem (German IT newssite) the new driver mainly reduces the max boost frequency by 50 MHz to prevent crashes.
Makes sense.

I’m seriously regretting not setting up a bot to buy the Rog Strix 3090 when it became available on BestBuy. It was available for a full minute and I wasted precious time refreshing Newegg after it immediately crashed. It’s not hard to do and I have the programming experience. Would have been able to purchase one in a second or two. Now I have to wait for god knows how long

I have received my MSI RTX 3080 Trio X Gaming yesterday.
It holds boost infinitely at 1980MHz and doesn’t crash.

Can I just confirm that you are using overclocking software such as MSI afterburner to get to that boost clock - I’m asking because that cards advertised boost clock is 1815MHz.
Damn you sir! You made me log in after all this time just to say LMAO!

Realistically, GPU is not the bottleneck at this point.
I am more excited to see what these cards can do on the new Ryzen chips that are coming out, but even then we will probably only see a few % points of uplift. We are talking a 7nm node that will realistically see a 30% boost to be optimistic.
Sadly for us, present CPUs struggle with ultra high FPS and high resolutions which all VR HMDs and just any modern displays really need.
I think the future of the GPU is going to have to be a device that handles all computation on board, that calls to the rest of the system as a backup.
To get blur free images on any sample and hold displays you need 500HZ BFI or 1000hz + without.
With VR, that needs to be done in stereo. Not an easy task if you don’t want to rely on synthetic frame generation or eye tracking alone.
With Nvidia’s recent acquisition of ARM (if it goes through,) I can easily envision a graphics card that has dedicated arm cores on board the GPU working through an AI driven X86 translation layer to handle the entirety of rendering onboard.
If the entire process can occur on GPU, you get to cut out lag, bypass bandwidth constraints, bypass proprietary CPU instruction sets, etc.
Imagine a GPU that has all the present stream processors, memory, etc. you find on a normal card, but augmented with an onboard SSD and arm cores used for frame rate amplification that takes place on chip.

they will boost as high as temps and power allows. normally this will be to a safe level so normal users having their cards crashing with normal use is a problem.
overclockers knows that they’re looking for the edge of instability so will expect their card to crash and will not see it as unexpected or a problem.
About my 3080 Trio X Gaming: No, I did not overclock it manually, nor changed the PT.
The card goes there all by herself. 1815MHz is just guaranteed minimum constant boost clock by manufacturer or something.
In IL-2 it automatically went to 1920MHz, but that Simulator also calls AVX Instructions on the CPU and my entire PC Case turns into a small sun. The game is far from optimized. Other Apps it was going to ~1980MHz and could hold it. It goes up to 72°C. I have the silent BIOs selected. Might try the normal one tomorrow.
I must say, the MSI engineers really did well with this one. This thing is crazy - while very silent. My 2 Valve Basestations 1.0 are louder (high pitched whine both of them).
P.S. I am on two PCIe rails, sporting a splitter, for 3x 8pin PCIe power cables for the card. The Bios complains in classic R2D2 fashion upon startup, but shuts it afterwards.

I can’t believe the 3080 X Trio reaches boost clock similar to the 3090 FTW3 Ultra. Wtf. Highest it overclocked to was 1980Mhz on the EVGA livestream.
How do you know all cards were affected equally? Did Nvidia give you a line to every crash report on the planet?
I don’t think that’s unusual. The 3090 has more compute units, more memory, and a wider memory path, which often means that the clock speed needs to be a little slower. It’s not much of an issue, since the 3090 can do more work per clock tick (due to the extra compute units) and the memory bandwidth is higher.
Even nVidia’s FE 3090 has a slightly lower clock speed than the FE 3080.

Ah okay that makes sense. So the 3090 will always be faster than a 3080 right?

“Always” is perhaps too strong a term. It’s possible that a seriously overclocked 3080 could beat a “standard” 3090. It appears that a 3090 is only about 20% faster than the 3080, at least in many of the benchmarks I’ve seen. That’s a small gap, which might be overcome with liquid cooling (or maybe liquid nitrogen).
The biggest difference imo, is the extra memory (24GB vs 10GB). I think I will be getting a 20GB 3080, preferably a Ti version in a few months. At that point, the yields should be up and “binned” chips which overclock better should be available. I think that sort of card would be nearly as fast as a “standard” 3090 and should be at least $500 cheaper.

20% is optimistic - from what I’ve seen so far (with pancake games) you will be lucky to get 10% - it might do better with VR but I’m not that hopeful. I was all set to get a 3090 but for such little seemingly increase I’m thinking might be better off overclocking a 3080. Clearly you might be able to overclock a 3090 as well but it’s not looking good so far.
