OcUK Zen3 review thread

If you'd have said to me early last year 2020 would be the year the entire world would get locked down and AMD were to become the gaming CPU champion, I'd have an easier time believing the first bit..!

Exceptional achievement for them to not only catch up, but to overtake Intel in such a short time span.
 
Any good (in depth) thermal/temperature analysis covering all the new chips? Curious how they fair compared to the 3000 counterparts.

PCgameshardwarede do a great job showing how Zen 3 demolishes intel in gaming ipc. You need to test at low resolution to test the true potential of a gaming CPU is what the intel fanboys use to say, and I agree lol. AMD wipe the floor with intel.

come at me DG with your Intel still superior IPC BS.

While the new Ryzens do great, 3200mhz ram on a 5950x against 2933mhz on a 10900k is not really something that should be interesting to a forum with 'overclockers' in the name. I still think the 5950X and 5900X are great buys and I might pick one up for a second rig but other reviews like overclock3d show a 10900k winning in games where it loses on the pcgameshardware site, e.g.

https://www.overclock3d.net/gfx/articles/2020/11/04150443424l.jpg

Which doesn't make the 10900K the better chip - just that most of us on here won't be running 2933mhz ram on it.

There's also the issue of whether it can beat something like a 5ghz 10980xe with both chips at max overclock (notwithstanding the extra power, thermal and money needed on the intel side), e.g. :

So there's a decent chance the 5950X will end up in my secondary rig if it can't beat x299 on a chiller. Again, doesn't make Intel the better chip all round but for an overclockers forum these are things to consider (and Threadripper has its own problems vs x299).

What? You're saying the 5950x isn't good for overclockers who want to set records? Mate all overclocking records were just broken today with a 6.3ghz 5950x, get up to date with the news :D

I've had a brief look at a review or two.

On the one hand the review says the increase in games from the 3000 series to the 5000 series is massive and yet benchmarks at 1440p show about 3% at best performance difference between a 3700x and a 5800x.

Depends what you're trying to do. In the likes of cinebench there's no doubt that the sheer throughput is fantastic - but then AMD already owned a lot of pure CPU benchmarks through their 64 core TR chip. 3DMark and things of that ilk, less so. TR can do TSE by virtue of sheer cores, even though the 3175 nearly matches it with 28 cores, everything else on the HOF is Intel atm.

The big draw this time was taking the gaming crown, which it certainly does at stock - but I'm not yet seeing it beat the likes of an overclocked 10980XE in that arena, which is also something that even Steve from GN alluded to in the end of his review. Early days yet, it might do. I would also say that the 5900x trades blows with the 10900K when both are overclocked, and thereby finally eliminates Intel's overall performance advantage in games but complete unbridled enthusiasm should probably be checked. It'll be fun to find out which to keep in a main rig and a lot of fun to overclock though.

His gaming benches are, he even says so.

I'm not sure if it's the selection of tests or the fact that we're running memory at 3200 MHz and AMD's numbers are at 3600 MHz, the silicon lottery, or something else. I even updated to Windows 20H2 for the scheduler improvements, as the Windows thread scheduler in version 1903 will definitely put loads on the wrong Zen 3 cores (I tested it). The performance loss without the update is a few percent, so make sure to update your OS when upgrading to Zen 3. I don't doubt for a second AMD's legal team didn't ensure their claims are waterproof, so I'll be digging deeper into what's going on, and will keep you updated.
