What's the Best CPU Benchmark?

There are SO MANY options for stress testing, but which is the best? We put not one but TWO systems through the wringer to find out.

With Labs coming, stuffs getting more scientific. With these videos, more logs/journals/results in a PDF/xls file be awesome.

Honestly, this is easily one of the most needed videos in PC Building. If it's possible to make the title clearer on what the content is, I'm sure many people would benefit as this will be relevant for many, many years and use cases

"You'll never know your limits until you try to push them."

I'm not a hardcore OC enthusiast, but even still I like to see how much headroom I have in my rig, if for no other reason than that I just like to know. Also, it's always nice to be able to disprove people who claim, authoritatively but absolutely without any backing, that "you're doing it wrong if you don't X". You know the type, "You should really water cool that CPU or you'll wreck it!" or "if you use the stock fan curve then your RAM will burn out over time", stupid stuff like that.

8:14 You can significantly cut the time down to reach steady state on water by shutting off the fans for 1-2 minutes at the start of testing

The hammer hitting the CPU physically hurt me

[Oliver_Kruse]

A huge recommendation for y-cruncher! It also checks memory stability with different algorithms. I had some systems stable with different stress tests, only y-cruncher disconvered the problems (usually the FFT/NTT tests).

I actually overheat my PC, so the lifetime of my I7-3770k goes down, so I can buy a new one soon.

I remember having this kind of issue back when I got a 6600k. I overclocked it to around 5ghz and was able to get into windows and run cinebench on loop with no problems. But in certain games (especially BF1), around 10 minutes of gameplay would give a BSOD. This kind of content is very useful to people getting into (amateur) overclocking especially, and honestly I would have loved this video back when I was starting to get into PC gaming.

I remember, when I first got my 4770k, Prime 95 Small FFTs was absolutely brutal in terms of heat output. It was only after a water cooling upgrade, multiple remounts, and a frustrated "crank the fans to max" run that I realized the test exposed Haswell's infamously bad TIM on the IHS and how the solution was devils' canyon.

[Eazon_]

My 5600x's Overclock was perfectly stable with long R20 loops and OCCT test, but actually P95 showed me its instability, with one of the cores clocking down to 1Ghz after around 10 minutes.
All it took was a 50mhz reduction and in 5 months i've had 0 crashes, but still goes to show that somehow prime can be good for stability

[WayStedYou]

1:24 I like how your silver bullet is an unfired round.

[williamvirkis]

These videos are becoming more and more rigorous and I really love it! Like really, these are University course material! I am thankful for the quality and love put into these videos!

[AsthmaQueen]

All the test types can be really useful for testing stability I've found I know when trying to find a stable overclock for Ryzen 1800x I was able to push 4.0 ghz (even topping out at 4.2ghz but resulted in crashes faster) and be stable in prime 95/aida 64 but soon as I did general tasks for few hours I'd get crashes. I ended up finding a test that presented this and it was a AVX workload of just trying use Handbrake to compress a video was easiest way to generate this crash. With that I was able to finally dial in a stable overclock.

[PierceMD]

Love prime 95. Helped me find out that my fans on my radiator were facing eachother. Back in 2016, I was using an FX-9590 in a CM HAFX case.

[joannaatkins]

It's very eye opening seeing how your home rig(s) deals with synthetic loads, I've had to modify several cases just to make sure the systems don't overheat in hotter months!

[SuperKiller]

Just wanted to point out that the link for a "free 240GB SSD" from Microcenter is actually for a 128GB USB Flash Drive & 128GB MicroSD Card

[chronoreverse]

You can add spikes to Small FFTs P95 AVX2 simply by waving your mousing so that it sends interrupts. Buildzoid does this a lot in his videos.

In my own experience, I get crashes in P95 far more easily when at the edge.

Nice little zoom/spatial blur effect there at 1:19. My compliments to the editor
