i7 3rd generation faster than Ryzen9 3900x?

[mclaren85]

I got a very strange result after benchmarking with Super Pi Mod 2.9 WP. My old Sony laptop, which powered by Intel i7-3632qm, calculates the pi digits significantly faster than my new Ryzen 3900x.. At first I think about that should related with the single core performance.. But wait, it is the older one which is getting better results.. Also that is a mobile cpu. So what do you think the reason is? Is Intel really faster than AMD in single core even it is older and even it is mobile??

Here are the results..

Weren't you the guy who locked that poor 3900X to 3.8 GHz thinking the 1.5v is killing it (when it clearly isn't)?

I don't think an unlocked cpu means that we have to oc before use.

You intentionally hamstring your CPU then wonder about it performing like shit.

Ryzens are the most dynamic CPUs by far and locking them down is like shooting an athlete in the foot while he is running. It's by design. Silicon will boost depending on voltage, power, and heat. It's not the same as setting a multiplier yourself and you deciding what's safe or not.

It boosts to 1.5v in order to ensure high single thread clocks at a low load, like a background task or service. Which will not damage the CPU. That is why you see lower single core boost when you undervolt a Zen 2 CPU. It doesn't have the voltage headroom anymore, because you intentionally handicap it. Same with locking its' multiplier. Under a full all core load, or gaming, a 3900X should see close to 1.32 Vcore, not 1.5v. That would kill it.

Wonder how many times we're gonna have to have this conversation until you finally get it.

Time to replace your AMD rig and get Intel!...

I respect your ideas but.. runing cpu at 1.5v in low load or whatever, is a big no.

 

[Selaya]

Your loss then.

Care to elaborate? Why is that? Due to electromigration, as you said before, which barely, if at all, occurs on low loads?

I'll say it once again.

High Voltage + Low Amperage = All good.
High Voltage + High Amperage = Fried transistors.

I'm not stopping you from intentionally kicking your CPU in the foot so if that's what you want to do, go ahead. I'll enjoy my stock boosting to 4.75 GHz.

 

[mclaren85]

Your loss then.

I can't even imagine how a newest Intel performs.. I have to admit, Intel is technologically way better than any other. They don't have to deal with any voltage shit or anything..

SuperPi uses the ancient Intel x87 instruction set so you shouldn't use it to compare systems. It's a great bench but practically useless for comparisons. Intel still supports this instruction but AMD relies on emulation for it to work which is a reason why they're slower.

Only Ryzen 5000 can comptete with Intel chips in this bench because of their IPC increase.

 

[Deleted member 205776]

You're also running Windows 10 LTSC which has no Ryzen topology awareness, as the latest version of LTSC is still based on build 1809. 1903 and higher have Ryzen awareness.

That sounds correct. Because When I did a render test, Ryzen always wins.

I would hope so since it has 3x the cores/threads.

I also forgot to mention, SuperPi is a purely singlethread application.

My first two iterations were with the thread randomly jumping around and the last (with the best score) with affinity manually set to the golden core. Each of those were way better than any of the OP's results.

But how can you live with those scores knowing that your CPU is suffering from completely normal high voltage while doing nothing, smh

 

[Selaya]

The only thing I did in the BIOS is enable XMP. (Yeah, I'm lazy like that. Should try 3600-16-16-16-36 at some point.)
I'll just go sue AMD if the CPU fries itself stock!111!1111

I don't blame you. After witnessing why people call RAM overclocking for masochists, I decided to just leave XMP on @ 3600 16-16-16-36 and just cut tRFC in half. Literally the same latency improvement (from 71 to 66) but much easier and stable.

 

[Selaya]

I mean I know what my memory is (4x8 of bad bin B-Dies from Corsair, with 3200-16-18-18-36 @1.35V XMP profile) shouldn't be too hard to figure something usable from there bc it's still B-Die but yeah rip laziness.

dude, you are using the wrong version. that is the latest one:

Download Super PI

Download Super PI 1.9 - Super PI is a application that can calculate pi to a specified number of digits after the decimal point by up to a max of 32 millions

Then why are you still here? Why haven't you sold your PC and bought Comet Lake or Rocket Lake? Why are we still here listening to you on your bizarre crusade against your own CPU, bitching about your 3900X?

After I've personally, patiently explained to you multiple times that it's current that Ryzen is most adverse to, and the stock boosting algorithm wisely reflects this in its design.

Frankly this is like dyno'ing a 4.0L 1GR V6 against a 5.7L 3UR-FE V8 and saying that the V6 must be more powerful because at 2000rpm the dyno graph makes it look like the V6 makes a whopping 125hp while the V8 makes 100hp. Well shit, I guess the designers are all lobotomized, we humbly defer to your amazing insight.

 

[Heres-Johnny]

Nope, this is the right version (mod1.5 XS) and the only version people should use.

You have to understand that nothing lasts forever. Run that cpu as it's meant to run. The older cpu's ran with more that 1.5V and were even capable of ridiculous overclocks. With all the safety precautions motherboards have these days you will have a hard time killing your cpu.

The stock voltage on my 10850K is 1.45v...so...
