Holy crap lol, a 3900xt would be really tempting but nah ima still wait for zen3
4.6 all core?
I hope so. With improved IPC it will be awesome. Can see myself picking it up a 4900X in 18-24 months time as they get major price reduction
Wonder if they'll bump the 4600 to be an 8 core part.
Would love this. Going from 4/4 to 8/16 would be worth it, just can't justify a 6/12 upgrade. Ideally a 12/24 but that's probably overkill and will cost £450+
Waiting for comprehensive benchmarks.
Frequency scalling alone would not appear to offer much uplift as that's not really the bottleneck.
We need to see how far the infinity fabric will go in sync on these XTs.
...which to most isn't worth it unless you have significant productivity demands.
An 8-core 4600 for ~£200 would clean up, however I suspect they'll maintain the core counts per model, at least for Zen 3. No commercial reason to give another 2 cores away at the moment.
Indeed. Reworking the CCX design into a single 8 core unit will net bigger gains than increasing core counts. 5nm shrink and a rumoured total rework of the chiplet design opens up possibilities for core count increases in Zen 4, but even then I can see that only happening at the lower and mid SKUs: 8 cores across the board with 12 and 16 if you want them. I could see a 5950X with 20 cores just to rub Intel's face in it a little more though, but unless Rocket Lake's successor moves past 10 cores (hell, rumours suggest Rocket Lake isn't even getting 10 cores) there's no commercial reason for AMD to move past 16.
I can see Threadripper holding station for the same reason.
4.6 all core boost would be a significant boost, I'd be surprised if this was the case. Current 3900X only do about 4-4.1 stock.
4.6 all core overclock is not unusual for people who bought Zen 2 cpus recently (from quick look at overclock.net forums)
tech process matures
And it will still be subject to power limits, so will not be held for long.
Most 3900X's that I have seen, mine included can do 4.3 fairly easily. I agree though 4.6 would be a big multithreading jump.
3800XT is looking tempting if it can do 4.6ghz all core.
mine is pish. 4.3 at the highest safe voltage. will do more with unsafe 24/7 voltage. I just leave it on PBO.
I ended up doing that too. I am mostly a gamer and on PBO 4 cores will hit 4.6-4.65Ghz so I just left it on that. It's better for me than 4.3 all core.
I'm on an x470 board with an older bios. mine doesn't get that high. will be getting the x570 tomahawk when its released.
I bought a 3900x literally 2 days ago lol, hope I don't regret it with these chips being monsters :V
4.6 all core on the 3900X would be very unusual.
Funny enough, I am on an X370 Crosshair VI Hero. Maybe I just got lucky!
how many 3900X bought after March 2020 and tested for overclock are there?
3600 is more common
Perhaps good 3900X bins are held from market to be sold as 3900XT, but 3600 are needed in higher numbers so some good silicon is now on the market
One of these would be a nice upgrade to my 1700 that is running in a Asus CH6, hopefully there will be a BIOS update.
