This one game is notoriously cpu heavy. Other people have shown dramatic gains doing similar cpu swaps. In my personal testing tested I have seen it waiting 6ms or more for the cpu and never waiting on the gpu at 1080p. If I use whatever super resolution software and set it to 1440p the gpu becomes limiting in some situations.

I got my 5950x for WCG crunching purposes. I don't need 16 cores although it is nice to have.

I don't think I have been experiencing this. My vrm's don't seem to have a problem staying cool. Maybe because I have a bench case?

And I guess that you have a good board with a good VRM? I guess that it runs cool even with your CPU?

 

[freeagent]

Games that *actually* prefer clocks over cache are very rare, and usually very old. Often times Vcache either makes no difference, or a massive difference (try something like 90 vs 150fps in Insurgency Sandstorm in cluttered scenes).

Either way, the 5800X3D is just better prepared for anything that comes down the line.

A couple months ago I could see the 5700X being a great deal. Now the X3D has come down significantly in price.

It took me a little bit to figure this out. Every few days I would drop the 59er back in, and a couple of days later I would pull it out. The X3D is actually a pretty good CPU if you are just an average gamer type, and not a hardcore power user. Even better if you are mindful of your power consumption..

In past stress testing I have not seen any VRM temp issues. I have not noticed any unexpected stuttering. I did a 40 minutes of P95 to see what HWinfo64 said for temps.

Is there a better way to test stress VRM's and or see temps than P95 and HWinfo?

I updated my System Specs a bit. It wasn't horribly out of date. I do have an open air case which might help with VRM temps.

I'm very excited to upgrade to a 7800x3D this week. Gonna be my set it and forget upgrade until Zen 6.

 

[Mussels]

If you have middling DDR4 and are not into OC, the 5800X3D is also a good choice.

You can totally OC the 5800x3D, and RAM tweaking is something that it benefits from too - it's just happier easier than other zen chips
3800 C18 runs amazeballs on this thing, and the PBO tweaking technically results in higher clocks, so its overclocking


You just cant static multi and voltage OC it

You may not - it comes down to airflow on the VRM's as their mid-grade rather than garbage. An AIO in many cases can result in a deadspot over them with no cooling, and the thermal pads on them can dry out faster than i've seen on other boards - i had to use a copper shim on mines chipset since it got annoying fixing it every year, but the VRM pads seemed better

He definitely had PBO enabled and boosting with "motherboard limits" (which meant 140W maxing everything out), which was part of the issue

My screenshot above was stress testing at motherboard limits. Although chipset temps went down, I don't think he info shows vrm temps.

My upgrade is complete. Was an easy and pleasant migration for once.

Even my air cooler is doing fine with it (albeit it's a beefy one with blower fans lol)

What memory did you choose to go with? I know you said G.Skill in your system specs but what kind?

I replaced the memory that I got free with my processor at Microcenter with a kit of G.Skill F5-6000J3038F16GX2-TZ5N. According to research, these are Hynix A-Die DRAM chips. Right off the bat I was able to achieve a slightly better Cinebench R23 multicore score and about 150 additional gigaflops according to Linpack Extreme. I'm going to say that that's because the new memory kit has a CAS latency of 30 as vs 38 on my old kit (Samsung DRAM). I also, with a suggestion from Level1Tech on YouTube, increased the fabric speed from a flat 2000 MHz to 2033 MHz which apparently can decrease memory access latencies.

Needless to say, I'm trying to eke out every drop of performance out of this Ryzen system of mine.

Flare X5's, specifically F5-5600J3636D32GX2-FX5

They appear to be Samsung high density dies of some kind, so Single Rank at least.

Why didn't you go with DDR5-6000? That's generally the sweet spot for Ryzen performance when it comes to RAM.

You really can't get there with 64GBs, unless you get really lucky.

Umm... my NewEgg skills beg to differ.

Granted, you're going to have to pay through the nose for it for the price is $275 USD, but it's available. Not only is it DDR5-6000 but the CAS is 30. Very good and it seems, at least for DDR5, the timings are very good. The only bad part is that you're going to have to pay top dollar for it.

The controller is the limiting factor on AMD, not the ram. You can get stuff spec'd for it but you won't get there easily on AM5.

There are some very few chips that can do it on some AM5 setups (I believe 16gb hynix something or another), but it's pretty much a crapshoot if your board and IMC can keep up.

I'd assume that if it has an EXPO profile it would work. Right?

 

[freeagent]

That's $400 ram here.. not bad actually.. pretty much what I paid for 4x8 3200C14

 

[R-T-B]

Depends on board and IMC. Speeds listed are not gurantees in all scenarios, no (though with a better board than mine you might hit that speed). 5600 for 64GBs is pretty safe though, hence my choice.

This is especially true when running 1:1 with the memory controller, which I am doing (this is a beneficial thing).

My 7800X3D tomorrow

 

[Nordic]

If I am swapping a 5950x for a 5800x3d I should clear my cmos, choose optimized defaults, and reinstall the chipset drivers. Is there anything more?

Update BIOS to AGESA 1206c or above

That's not the sweet spot - that's the maximum you can possibly get, with low ram amounts.
The "Sweet spot" for Zen3 was 3600, while the max OC was around 3800 - but you add four or 8 ranks, and you're back at 3600 most of the time, 3200 at worst.

update the BIOS, then load optimised defaults. Saves some time.
If you use Bios flashback, i've had to clear CMOS prior to it working on some boards. No idea why.




This video shows something of a problem

He simply tested 13 ryzen 7600 CPUs, and they werent consistent in performance, power consumption or clock speeds.

It's important to note these have the power limits disabled and are on a high end board - if the power limits had been engaged, the ones with crappy IHS contact might never have gotten hot enough to throttle, for example.

AMD Confirms DDR5-6000 RAM Is The Sweet Spot For Ryzen 7000 CPUs | Tom's Hardware (tomshardware.com)

The Zen 4 parts have a default FCLK of 1,733 MHz, supporting DDR5-5200 memory by default. (Robert) Hallock (Director of Technical Marketing at AMD) believes that DDR5-6000 will be the sweet spot for Zen 4 based on cost, stability, performance, availability, and ease.

My boss finally got his 7950X3D! He's building his new rig as we speak, it's going to be an absolute monster from my understanding. If he shares some benchmarks with me I'll show them off here (with his permission).

On the topic of the X3D chips, I did briefly consider upgrading from my 7700X but decided against it in the end. The X3D chips seem to be a bit "odd" from the Windows scheduler's perspective and it seems they require a bit of tweaking to get right? Meanwhile my 7700X is more traditional which means it works out of the box with no fuss.

(Not that my needs warrant an X3D chip anyway, it'd be for pure bragging rights. But then again I keep getting blown away by the 7700X anyway!)

Yeah, tomshardware misquoting things never happens at all


And the discord->twitter-> Toms source: Oh right purely about Fclk and not the misleading headline at all
