High CPU clocks?

[NexusHUB]

Hey all just noticed something, not sure if it's been discussed before but I wouldn't even be sure how to search for it.

Just now noticed the free build option so I could finally play around with some high end parts. Then I noticed these enormously high listed clocks for CPUs. 4.2GHz on a 7980XE? Or the same on a Threadripper 2990WX? Is this some sort of auto overclocking? Because those are WAY higher than their real world counter parts. I couldn't manually get the 7980XE clocked any higher either, and I actually had to manually UNDERclock the 2990WX to get it stable, both of these on custom liquid cooling loops.

What gives? Does the game notice your choice of cooling and automatically adjust the CPU clocks? What's the point of including simulated overclocking in the UEFIs then?

https://en.wikipedia.org/wiki/Skylake_(microarchitecture)#High-end_desktop_processors
7980XE has a maximum boost clock of 4.2 Ghz (4.4 Ghz under Turbo Boost 3.0 if enabled) in real life.

https://en.wikipedia.org/wiki/List_of_AMD_Ryzen_microprocessors#Desktop_processors
AMD Ryzen Threadripper 2990WX has a maximum PB2 boost clock of 4.2 Ghz In real life.

All default speeds for all processors in PCBS game reflect their actual maximum boost speeds in real life.

Ryzen 2990WX is a -VERY- hot processor and it can actually run at it's listed maximum boost speed of 4.2 Ghz, by default, in every computer, if you give it good enough cooling.

Alright, what still confuses me is that the game behaves as though the max boost clock is the base clock. Motherboards don't typically list the max boost clock as the multiplier, it's the base clock.
And yeah, by default in PCBS, even with custom liquid cooling, the 2990WX throttles when under load, which suggests that it's running that fast on all cores. Perhaps it' not fully integrated? Maybe a bug?

Add some more radiators to your loop and case fans can help bring the temperatures down.

That's how it works in real life too. All processors will attempt to hit max turbo boost speeds out of the box if you just plop em in a system and don't do anything. If you can't cool em properly, they throttle. This is how computers work. And the 2990WX like I said is extremely hot, use custom liquid cooling. It's a 32-core processor for pete's sake. It's -HOT-.

Have you some how been living under a rock and haven't looked at technology in the past 5 years? Almost all modern processors have some form of turbo boost and they all pretty much work the same.

You, like, completely ignored what I said.
Of course I know what turbo boost is. Obviously I know that CPUs try to go as fast as possible out of the box. But it isn't on all cores, the game seems to behave like it is. As I said.
It literally took me 20 seconds of Googling to find an AIR cooler rated for the 250W TDP that the 2990WX operates on, let alone a custom cooling loop. It should not be throttling at stock. That is ridiculous.

So if you're gonna toss a veiled insult at me bud, at least have it be about things I actually said.

No one's trying to insult you.

However I am trying to figure out what you're going on about. I just loaded PCBS, and I threw together a quick 2990WX build in free build mode. Random TR4 motherboard, stock CPU, and I just used a EVGA 280mm CLC/AIO and it doesn't throttle, even at 4.2 ghz.

I had a different result the first time I tried it. Tried it again and had it inexplicably run more stable, but the main issue I had was the wonky listed stock speeds.
The main stat of any CPU is its base clock, not max boost. So I'm just wrapping back to my main question: why is it listed at 4.2GHz on both these processors? Max boost clock is an unreliable stat.

In RL i have a I7 8700 with 6 cores and 3,2Ghz. In Time Spy i got an CPU Score round about 7800 with 16gb Ram at a clock rate of 2133mhz. Tried the same in PCBS with the same MB and the same Ram and the same CPU. The In PCBS i hit a CPU score of 7556 at a clock rate of 4,6Ghz. I think the PCBS CPU´s behave almost like their RL counterparts just the BIOS and System Info show the max clock rate in Turboboost. Thats the thing that should be changed. I tried the I7 8700K in PCBS and underclocked the CPU to 3,2Ghz so it can be compared with the RL I7 8700. Time Spy score was below 5500. So CPU behavior is like it is in RL. BIOS displays it wrong.

Thanks for that!

It's especially weird when overclocking then. Makes me wonder what exactly that's doing. Bumping the max boost clock?

[maberickxx88]

I think that is what it does. If you overclocking your CPU you will also rise up the standard clock rate and the Turbo Boost

Actually this is incorrect. When you "Overclock" your computer in real life the only thing you're actually doing is raising the maximum allowable turbo clock speed so under load it will hit a higher maximum turbo boost. Even overclocked processors in real life will still drop down to their low idle speeds.

And it does seem in-game that the game is listing the processor's maximum turbo speed as it's actual speed in the in-game list. Personally I don't see anything wrong with that. I've always thought that all processors should be advertised at their maximum all-core-active turbo speed in real life. It's often rather deceptive that they advertise cpu's at one speed and they run much higher in reality.

Actually, it's not inexplicable. They implemented the silicon lotto in this game so every 2990WX will perform slightly differently than other 2990WXs. This is the case for all CPUs, RAM, and GPUs.

The problem is that a max boost clock can usually only be achieved on a single core. I don't believe I've ever seen a CPU hit higher than its base clock on all cores, higher clock speeds are achieved on less cores.

They implemented silicon lotto?

Yes. Every CPU in this game has a RNG assigned to it when you pull it out and when they come from customers in career mode for 3 stats: Power, thermals and overclocking.
