What is the maximum PR number a processor can achieve?

[Robertomcat]

Hello, good morning.

I am currently using two 10900K processors for the Metatester, which have a PR of 266 and 264. Now I have added a 14900K and the PR figure has become stuck at exactly 300.

This makes me think that this is a maximum figure, since it has no oscillation. I cannot confirm that this is really the case, but seeing such a completely exact figure on a processor that should be above 300, makes me think that a maximum has been estimated. Please, could someone clear up my doubts?

It seems likely that the MetaTester enforces a Performance Rating (PR) cap at 300. Normally, PR values vary slightly, especially with high-performance processors like the 14900K, so seeing a fixed PR of exactly 300 suggests a system-imposed limit.

To confirm, you could try running a benchmark using only the 14900K to see if the PR exceeds 300 on its own.

At the moment the figure has not been exceeded, and I suspect that by staying at that figure of 300 and not moving, the figure that could be obtained is surely higher. This would have to be reviewed by the software developers, processors evolve and become more powerful and there is no reason for it to remain at that fixed PR figure. Thank you for your response.

They probably set that limit for good reason—to prevent too much "priority" being given to the extra high PR computers, and to distribute the workload more fairly among all the other computers of high PR.

EDIT: This is my opinion. I am not speaking on behalf of MetaQuotes.

So this is a limitation when performing tasks if there is a PR restriction. Why would I have to invest in a more powerful processor that performs tasks much faster than others, if I can put a less powerful one that does the same thing? It doesn't make sense, because there will be more and more powerful processors, simply by evolution.

I was not speaking for MetaQuotes. I was only expressing my suspicion (an opinion).

Oh no, I wasn't talking about you. I know you've been very active on the forums for a long time, but I didn't think you were to blame for this. It was just my thoughts, because technology is moving forward. But if you can tell someone you know about this, I'd appreciate it.

Here is your cpu at Intel:

Total Cores                        24

# of Performance-cores      8 // running at full speed

# of Efficient-cores          16  // running at a lower speed, for the sake of efficiency !

Here you can see that only AMD Ryzen 9 9950X ist the fastest for applications (green 100%) as it has 24 kernels that are all running at full speed.

But the efficient cores are disconnected from the motherboard, therefore only the P-Cores are working, hence the high PR figure.

Yes, according to statistics it is clear that 14900 has reached 300 PR en masse.

We will raise the limit and do the analysis tomorrow.

Thanks for the information!

How can we run a PR benchmark? Thanks
