HP Elitebook Poor CPU Performance - HP Support Useless

[rdwrx]

Bought an Elitebook 840 G6 off eBay a couple of weeks ago, 8GB Ram 256Gb HDD, i5-8265u. All seemed fine initially however upon Geekbench 5 I've received reasonably poor performance for the given chip. They seem to average around 3000 on Geekbench 5 Multi-core, however, I'm receiving around 2300, not dreadful however not the performance I paid for. I appreciate synthetic benchmarks only provide so much of an insight, however, CPU utilisation has also been uncharacteristically high in music software I've tried on the machine too. I initially tried many fresh installs of windows, driver installs editing power setting, however, scores were still disappointing. using HP's image Have been on contact with HP support and they have been honestly useless, with the past couple weeks consisting of aimless troubleshooting, useless driver and HP Bloatware installs and them seeming to not understand the issue with the device, interpreting my issue as a 'lag when I try to run geekbench software'. Over the past couple of days, I finally managed to get through to what HP describes as their 'next level technical team' who I thought might finally show some initiative. They looked through the full system logs and couldn't find anything of note, then instructed me

'We are not trained on these applications and we are not aware of it's specification or behaviour or its settings. But there is an issue while using this applications.
So we would request you to contact the  Geekbench 5 benchamark support team for further assistance'
So it seems their 'next level' support team has also failed to understand the issue and the purpose of the benchmark itself. I've contacted HP again to further express my point, however, I was directed again to contact Geekbench. I assume, through all my troubleshooting that it is presumably a bad chip in my unit, 'silicon lottery' stuff, however, if there's anything obvious I'm missing I'd appreciate anybody's input. If anyone also has any ideas on how I can get HP to budge on their completely ridiculous stance on the issue, either misunderstanding or outright denying there is an issue, I'd also appreciate it. The unit is still under warranty.
Thanks in advance for any help.

I would say the average is more like 2800:

HP is just not going to recognize a third-party synthetic benchmark as representing anything HP is obligated to deal with. As long as the computer passes the built in performance testing it will not be eligible for any kind of warranty help. Try running the Intel processor identifier which I believe will tell you the core speed of the processor and make sure its actually running at the speed its supposed to run:

Thanks for that.

Appreciate your point about Geekbench, may have to rethink how I make my case to support. Processor identifier report is as follows. Base clock seems okay, not sure what I should  be expecting for reported clock.

Thanks for your help.

Hello

I'm going to downlaod that software , is it for free to run it ?

Could you provide the SSD model you have inside you notebook ?

Using Device Manager you should be able to find it.

it's important to know also:

BIOS version

Windows 10 Version

Bye

Hi, thanks for your assistance. If the software you are refering to is Geekbench then yes, it is free to run with some limitations, but nothing that should prevent you from getting a usable result.

SSD is a Samsung MZVLB256HAHQ-000H1.

Windows is version 1909 however has also been tested on 2004.

Bios is version R70 Ver. 01.05.03

Thank you.

Hello

using Core i5-8365U, 8GB

CPU Benchmark only

1st   run , Power Plan: balanced               : mc 2488  , sc 694

2nd run , Power Plan: High Performance: mc 2455 , sc 982

3rd run , Power Plan: High Performance : mc 2234 , sc 519

4th run , Power Plan: High Performance : mc 2434 , sc 1034

Then I disable a software that , in Task Manager, I saw it using a lot of CPU power

5th run , Power Plan: High Performance : mc 2417 , sc 1018

6th run , Power Plan: High Performance : mc 2484 , sc 1038

7th run , Power Plan:  Ultimate Performance : mc 2464 , sc 1043

what Geekbench doesn't report are:

Windows 10 version and build ,  I saw bechnmark reporting huge differences between Win 10 version and driver versions.

BIOS version

all driver versions

If you take of look to the results there are huge differences in the results even among same model HP or not HP.

Thanks for your time in preparing these results, really appreciate it. I presume the thermal limitations of such machines make these synthetic benchmarks unreliable.

From this it seems I will have little luck furthering my claim with HP, but shouldn't suffer too greatly in the performance of my machine. I guess I will just have to accept this.

Thanks to both of you for your time.

Hello

thermal is very important

I tried to disable in the bIOS the power management and idle state and I got Single Core 433 and MC: 1771 !!!

I'm using a 840 G5 since a couple of years with 2x8GB , Core i5 and I'm satisfied by it.

bye
