Any way to tell the difference?

I guess the obvious answer is when it doesn't work well!
Someone else posted this but I'll repost it:


Not sure if it was in this thread or another one. That's all I know.

I had a Ryzen 5700G fail on me.

I had a build that worked fine for a couple of years, and then started hanging or rebooting every couple of days. I tried replacing the power supply, which didn't fix the problem, so I ordered a new motherboard, which also didn't fix the problem. I was pretty sure that faulty memory would produce memory errors rather than hangs and reboots, but I ran a full pass of memtest anyway--no errors. So that left the CPU as the only possibility. I installed a 5600GT CPU and the computer is working fine.

I posted this because I've never heard of a CPU failing unless it was damaged by overclocking. Recent generations of CPU's have less overclocking headroom than older generations. Perhaps AMD didn't leave enough headroom on my 5700G, so that with the natural deterioration that occurs over time even it a CPU that isn't subject to the stresses of overclocking, the CPU reached a point where it couldn't function properly at stock speeds/voltages.

That's the thing. Mobo makers are not above applying minor overclocked settings and overvoltages in their default BIOS profiles to try to give better scores in benchmarks. The CPU could also be a really poor bin unable to handle anything but stock voltages. The BIOS could be really old and maybe it was applying incorrect voltages. A normal, perfectly working CPU isn't going to degrade on its own under normal conditions so the only thing I can believe is that something about the conditions (mobo or PSU related) it was running under, wasn't normal.

Regrettably, that is no longer the case. Intel 13th and 14th gen raptor lake have suffered serious degradation issues using OOB settings. It is presumed to be successfully mitigated now that they have found all of the issues causing it, but only time will tell. Reports of degraded or broken Ryzen 3600s also happen too frequently. I have seen sporadic reports of Cezanne APUs failing, but not nearly as common as Zen 2.

As stated, you are far from the first person I've read with a degraded/broken AM4 CPU. If you monitor with HwInfo and you are running OOB settings you will probably see 1.5v+ vcore under the max field. I have been manually applying settings on AM4 since 2018 due to it. All of the boards I have now are either ECO mode with +200MHz PBO or a negative offset with curve optimizer. It would not surprise me to learn that years of use, with how aggressive the settings are OOB, has resulted in accelerated degradation. I recommend using ECO mode stat.

Via Ryzen Master, under Windows, or are you doing something extra? Can you please share the settings and explain why you chose them? I think others could benefit from it.

I am only changing a couple of settings in the UEFI.

XMP profile for ram. I don't mess with other timings.
ECO mode for vanilla Zen 3 along with the +200MHz PBO boost. These may require a bios update depending on the board.
Curve Optimizer for 3D CPUs. I start with -20 and if it is rock solid move to -25 -30 -40 wherever its stable limit is. That's it, nothing involved or overly time consuming. I am not a benchmarker or overclocker, and I am not trying to squeeze every last iota of performance out of my systems.

Weird review at Computerbase since the 5800X3D is EOL, neverless it is tested
with the 4090 and 5090 GPUs.

I enjoyed the article. Neat to see how well a 5800X3D can drive the fastest GPU in some games. On a platform that dates to the last decade no less.

The Nvidia driver bug is still not fixed -



Would have like to seen it tested with a 14900K so we can see if it only affects AMD.

Iceberg put together an excellent AM4 retrospective of every generation of 8 core CPU. He is using a 7900XT in PCIe 3.0 mode so there are games where the 3D could stretch the lead. He uses CPU demanding titles and ray tracing to load them up.

He points out that while DDR speeds were limited back in 2017 he can now run his ram at full speed with the 1700X.


I don't get the kind of drops he is seeing with a 5600X3D after playing for a bit in Spiderman. I think because he loads a save and swings down Broadway for a minute, there are still assets loading in the background. Nevertheless the performance jump Zen 3 brings is on full display.

That's a bit surprising. I would've expected a better uplift from Zen 2 but it seems to only match Zen+. Zen 3 is a big jump as expected.

I will be replacing a 5900X for a 5900XT in my main machine, which does mostly video and audio processing, and only very occasional gaming.

So far, I ran the 5900X at stock, but DAPUNISHER's post - see above - makes me wonder if the new CPU wouldn't also benefit from enabling ECO mode and the 200MHz PBO boost... Can anyone with direct experience with this CPU confirm? Much obliged!

Also, loved the AM4 retrospective video. I was surprised to see how well the 2700x held on against the 4700G (I had no idea that CPU even existed). Then again, its closest Intel counterpart would probably be the i7-8700 (non-K), and that's still a very usable CPU to this day...

For that purpose go for a 5950x IMO.
