Also - why avoid Zotac? They've had pretty good build quality cards in the past; I've had no issues with them.
They all use POSCAPS and suffer the problem. Asus and EVGA only ones confirmed so far to be properly built.
EVGA has just confirmed they discovered this issue in QC and fixed it. This is a super bad look for AIB's.

During our mass production QC testing we discovered a full 6 POSCAPs solution cannot pass the real world applications testing. It took almost a week of R&D effort to find the cause and reduce the POSCAPs to 4 and add 20 MLCC caps prior to shipping production boards, this is why the EVGA GeForce RTX 3080 FTW3 series was delayed at launch. There were no 6 POSCAP production EVGA GeForce RTX 3080 FTW3 boards shipped.
But, due to the time crunch, some of the reviewers were sent a pre-production version with 6 POSCAP’s, we are working with those reviewers directly to replace their boards with production versions.
EVGA GeForce RTX 3080 XC3 series with 5 POSCAPs + 10 MLCC solution is matched with the XC3 spec without issues.

I'm guessing the AIBs were forced to reduced costs due to product tiers and marketing, and also management. Not that uncommon, but still a bit shocking. The engineers and technicians of these companies are really smart, but they are overruled in many situations.
Based on reviews, the ASUS TUF Gaming, and the EVGA XC3 series seem to be the best cards at the moment.
Wonder any AIB will release a blower-style, or an ITX form factor card.

Possibly, but if EVGA/Asus are finding out about the power cap issue in QC testing and the others aren't and are releasing gimped cards that's still super bad.
Blower style no, ITX I doubt as well.

If it’s still hitting the advertised boost clocks that the AIB claims, then in that sense it’s not “bad”.
At that point it’s just an issue of not a lot of overclocking headroom

Exact opposite, the boost clocks are what is causing the crashes. They can't handle the boost due to the poor cheap POSCAPS. That is exactly what is causing the issue, and why he says he doesn't think AIB's will fix the cards but instead issue a VBIOS update lowering the boost clocks.
HardwareUnboxed is completely refuting this claim by Jayz and his testing however. They say all the cards crash the same amount regardless of the caps used and that the real issue is still unknown. LINK

The crashing with the RTX 3080 cards doesn’t appear to be down to the caps used, which is why we haven’t made a video yet, we don’t know the issue. What we do know is the FE and TUF Gaming models crash just as much as other models and they use MLCC’s.

Super interesting what Jay said about noticing noise/interference from his mic was causing their benchmarks to fail

Hmm, maybe I’m misunderstanding the issue but in the video Jayz explained that the cards were still hitting advertised/guaranteed clocks, but that the issue was with GPU boost thinking it had headroom and then the cards crashing because of the tables in the VBIOS that dictate GPU boost based on power/temp inputs

Oh my if true yeah I'm upgrading.

AMD Ryzen 9 5900X “Vermeer” 12 Core & 24 Thread Zen 3 CPU Allegedly Up To 5 GHz With 150W TDP
As for the alleged specifications, the AMD Ryzen 9 5900X is said to feature an IPC improvement of up to 20%. One of the main areas of improvement where AMD has put lots of effort into tuning on Zen 3 is the clock frequencies. As such, the AMD Ryzen 9 5900X is said to reach boost clocks of up to 5 GHz.

Pair that up with a 3090 and you'll have quite the space heater

Really though it's only 25W more than 10900K with 2 more cores and 4 more threads.
Posted on 9/28/20 at 1:06 pm to UltimateHog
Anything on 5700x/5800x? Hopefully one of them is a 10 core.

Extremely doubtful they go 10 core, would mean a major redesign. It will all be the same cores/threads just boosted clocks and better IPC - although I tend to doubt the 20% claim, that's a bit ridiculous on a mostly refresh. Going from zen to zen+ and that was 14nm to 12nm, not 7nm to 7nm like zen 2 to zen 3, was way less than 20% IPC improvement, think iit was what, 5% or less? I think most of the gains will simply come to clock speed increase, especially if they can get best models up to 5ghz out of gate.
Probably something like this just by guessing:
3600xt (6c/12t) 4.5ghz boost -> 5600x (6c/12t) 4.7ghz boost
3800xt (8c/16t) 4.7ghz boost -> 5800x (8c/16t) 4.9ghz boost
3900xt (12c/24t) 4.7ghz boost -> 5900x (12c/24t) 5.0ghz boost
3950x (16c/32t) 4.7ghz boost -> 5950x (16c/32t) 5.0ghz boost
Increase base clocks by about 200mhz across range too.

5800X is 8 Core. No 10.
Posted on 9/28/20 at 5:40 pm to thunderbird1100
Zen 3 is a brand new architecture, it isn't a refresh. It's on 7nm+ not 7nm. I would guess 15% IPC based on the leaks, 20% is ambitious.
quote:
AMD has so far confirmed themselves that Zen 3 brings a brand new CPU architecture, which helps deliver significant IPC gains, faster clocks, and even higher core counts than before. Some rumors have even pointed to a 17% increase in IPC and a 50% increase in Zen 3's floating-point operations along with a major cache redesign.

Now we're heating up on the leaks.

The leak I want to hear about is when they go on sale

If that’s the case I’m probably back with team red, I have a unopened x570 tomahawk waiting on these bad boys to drop so hopefully they are obtainable.
Also thanks UH, the other day you made me rethink what I was doing and I seemed to be falling into what I knew from the past with Intel. After a little research it’s apparent you get way more for your money with Zen2 and hopefully 3.
