Maybe this time.Why does AMD not completely fix their heat/voltage problem with the 3D cache chips?
My 7950x is stock/pbo disabled 6400C30 2133 with tuned timingsJust as a note for my 7950x run quoted above, i ran static 5850mhz for my submission (this is pretty much a ST benchmark)
And you have to use LibreCalc, its much faster than excel
Test date: 13.02.2023
CPU: 7950x
#Cores: 16Cores/32threads
CPU clock speed: 5850mhz
Total system memory: 32Gb DDR5
memory speed: 6600MT/s, 2200FCLK (same results @ 6400MT/s)
Libre office version: 7.5.0
32/64 bit: 64bit
time to sort (in seconds): 14s (first run)
time to sort (in seconds): 9s (second run)

Not for Apple it seems. None of their SoC's seem to have issues at launch. Thats vertical integration and a great validation team for you.Laptops are hard!
You are quoting a source that cannot be trusted. The same source is citing Igor for a different Zen 5 chip and even he says his information is 2nd hand. 3D v-cache CPU's are a gimmick. It reminds me of B-Die memory. Is it better? Sure, but not the price premium that they are charging.Maybe this time.
AMD Ryzen 9000X3D CPUs To Feature Full Overclocking Support In Addition To New 3D V-Cache Features
AMD's Ryzen 9000X3D CPUs will feature full overclocking support at launch, marking a first for the 3D V-Cache chips.wccftech.com
Best Buy has changed the release date of the HX370 Proart notebooks from 7/15 to 7/28.
Most MacBooks ever made are RMAcore with grievous PCB design issues.Not for Apple it seems
Umm... huh? As a Stellaris player I beg to differ.3D v-cache CPU's are a gimmick.
Talking about only the SoC/firmware/PDN.Most MacBooks ever made are RMAcore with grievous PCB design issues.
Please.
I'm well aware of that I did say "maybe"You are quoting a source that cannot be trusted.
its a whole lot less of a gimmick then the peasant core spam their competition is doingYou are quoting a source that cannot be trusted.

Skymont can no longer be considered peasant. So peasant+?its a whole lot less of a gimmick then the peasant core spam their competition is doing
Oh they had oopsies there too, now and then (with ISPs in particular).Talking about only the SoC/firmware/PDN.
its still peasant, IPC * Clock = Performance. they still going to be like 40-50% slower.Skymont can no longer be considered peasant. So peasant+?
V-Cache is a smart technique and it’s beneficial to gamers.
That's pretty great! I guess you wouldn't upgrade just to shave off two seconds moreJust did it again twice to be sure, it's 13s first run, 8s second run. My guess is newer libreoffice might be slightly faster than when you ran it?
paging @igor_kavinski did your mystery CPU run it on the latest librecalc?
If I did upgrade it would be to a 9950X3D. It would be irresistable if both CCDs now have V$, V$ size increased, if overclocking is unlocked, etc.That's pretty great! I guess you wouldn't upgrade just to shave off two seconds more
Librecalc version 24.2.4.2
Add my "possibly" to your maybeI'm well aware of that I did say "maybe"
Peasant on steroidsits still peasant
Doubtful.both CCDs now have V$
Doubtful.V$ size increased
Possibly.if overclocking is unlocked, etc.

V$Zen5 is very possible having similar frequency as Zen5, also dual V$CCD option is still possible. Yield of V$ improve quite a lot.Doubtful.
so they going to die, paranoid , acne riddled and young ?Peasant on steroids
Problem is, AMD makes a lot more by placing a single cache die on a CPU than if they were to place two dies on the same CPU. By placing two dies on the same CPU, they would have to recover the extra margin direct from the customer which would make the CPU very expensive and too unattractive for mass market appeal.Yield of V$ improve quite a lot.
7950x3D ended up costing pretty much the same as vanilla 7950x. Or the price-difference was like hundred bucks. Under those circumstances, Dont think that adding another v-cache die should somehow make such hypothetical CPU “very expensive”. If someone is gonna feel that way, they very likely already considered vanilla price to be that.Problem is, AMD makes a lot more by placing a single cache die on a CPU than if they were to place two dies on the same CPU.

What AMD needs is something like Intel Thread Director, a hardware solution that dynamically and in a fraction of a millisecond, schedules the workload on the appropriate die. They could make things easier for themselves by doing the "software hints" thing that Intel has done and then game developers or any other developers with cache hungry software can hint to the OS to run their instructions on the V-cache die only.
The supply of V-cache dies being a limiting factor, using two of them in a single CPU prevents the "birth" of another CPU.Dont think that adding another v-cache die should somehow make such hypothetical CPU “very expensive”.
