Did you switch the TR modes between gaming / creation and UMA vs NUMA memory or turn of SMT?

TR is not the most ideal pure gaming platform, but it has lots of room for tweaking and the 1920X reviews did highlight what settings work best for gaming.

How hot does yours run at 4.7?

Mine is running quite toasty - during intense gaming sessions temps go into the 80's. I went back and re-seated the heatsink with a tried and true method and still the same temps. I can't even run prime95 without getting too hot for my comfort.

Damn, sounds like a really bad TIM application from Intel then, can't think of another reason apart from inaccurate probes why the temps would be so high esp for gaming.

Just as a context the only way I can get such temps is by stress testing my 8700K at 5GHz or running AVX code (with -2 offset). Gaming temps for me are much lower, around the 60s, and this at 5GHz on air.

Indeed. My best guess at this point was that I got a crappy chip. Although this chip does run hot for a lot of people from all my googling, I think mine is just on the weaker thermal performance side. That being said I'll take the temps of spiking into the 80's while gaming and 70's while editing media.

Diablo3 higher rifts issues are mostly server side bound, players have been complaining about it for ages.

The game runs fine even on lower end systems as long as your network connection is good/excellent. I had no issue running D3 on a sub 3Ghz Haswell chip, with high rifts delays/freeze being the only problem, but that was always experienced by all members of the party, the AoE effects slow server response down to a crawl. Even the hour of the day makes a difference sometimes.

I have been playing the game since it came out and yes there are server side issues however the game plays bad on Ryzen. Overclocking all cores to 4.1ghz and disabling SMT fixes 90 percent of my issues in the game.

I tried everything. I researched and then I tried again.I spent over a thousand dollars on the CPU alone. The custom loop was another five hundred. So I really didn't want to spend anymore money. The gaming performance was terrible but not in all games. It shredded Wolfenstein New Colossus maxed but that's not open world and Vulkan doesn't seem very heavy on the hardware.

All I can tell you is what I have observed actually using a 1920x for around 12 months or so. It's not good for gaming and I was squeezing everything I could out of it. One difference I have noticed is that the 8700k gives more consistent fps. Whereas the 1920x used to have large fps drops and spikes in games like Far Cry 5 which was causing jagging and other issues.

How did you spend $1000 on the CPU when its original retail was $799, and now its $485 ??

Because I pre-ordered it and I live in Australia. The current retail for that CPU is 960$. I paid 1149$ for it. The total of my TR rig including the graphics cards which are 2 Gigabyte Gtx1080Ti AORUS Xtreme edition @ 1300$ each they retail for 1249$ now. I should have waited......was ~7500$.

So yes. I tried to make it work as a gaming machine but it sucks for that purpose. YMMV.

At least I was able to reuse the graphics cards etc.

... plays bad on Ryzen. Wonder why that is.

There are very few niche cases where an 8core ryzen will beat an 8700k by enough of a margin to sacrifice all of that ST performance.
It's great that a 1800x might slightly edge out a 8700k in these niche tasks but, how many users really want that benefit at the expense of hobbling every other task they do? I was considering a Ryzen1800x for my home workstation(vSphere\HYPV) and was almost willing to put up with all of the Ryzen's issues but, then the 8700k came out.

AMD Has had 8core processors in the market for years under $100 no less and no one wanted them. Ryzen's in the current form is just a repeat of this.

I wanted TR and was ready to buy one now that all of the stability issues have been worked out in esxi and CAD but, Intel released SKX and CFL and there is literally no reason to choose ryzen anymore unless you are on some sort of budget.

Mark my words if AMD releases a multicore CPU that's within a few percent points of Intel i would spend money on it in a heart beat but, 15-20 percent less performance per core? Noway

The only AMD product thats interesting is EPYC. I purchase 20-30 esxi hosts a year and the thought of 32core single socket 2u servers with enough lanes for 6-8 pcie cards makes me giddy.

So after openly stating Ryzen makes no sense against Coffee Lake 6c/12t, you somehow chose to buy the 2700X anyway: the 8 core CPU that according to you nobody should want. Would you like to share the reasoning behind major change in your purchase decision?

I never stated ever that the Ryzen 2700x made no sense over a 8700k. I was talking about the Ryzen 1800 which was absolute trash and still is. I have had a 2700x for a couple months and while it handles games well there are instances where the Architecture performs poor. I purchased a 2700x because my gaming rig is MITX and I figured the 2700x being 12nm would run very cool in the case.

installed Afterburner and started monitoring my temps while playing Far Cry 5. Temps were ok, mostly 60's and some 50's with spikes into the 70's. I can live with that.

This doesn't make sense to me since a 2700X isn't much faster than a 1800X at all - we are talking less than 10% overall so if the 1800X is 'absolute trash' for gaming then the 2700X is barely any better.

FWIW you may be surprised to see that a 2700X actually draws more power than a 1800X...

It won't do that on a mITX board - since all SFF Ryzen boards that I know have modest VRMs and - more importantly - weak VRM cooling. I doubt they would come with aggressive stock settings.

So is the turbo boost essentially gimped on the SFF mobos? Is a 2700X forced to run at base clocks rather than max turbo? If that is so wouldn't a 1800X also be limited in this regard?

AFAIK you can still adequately run 8c/16t SKUs on SFF mobos, but they'll probably stick close to TDP. The new B450/X470 mobos may be better revisions of the first models, but when I did my research with the first gen models, all of them had some issue with VRMs - not in the sense that there was something really wrong with them, but rather that VRM thermals would dictate mild overclocks at best. It's all highly dependent on loads and case thermals/airflow ofc, but if I were running a 8c/12t Ryzen on a mITX board I would be more interested in VRM temps rather than CPU temps.

Now that the 9th generation is around the corner I'm looking to snap up a 8600/8700k for cheap 2nd hand once people start to offer them. Since I have a SFF system with a power supply of only 150W I'd like to bring the TDP down from 95W to ~65-70W range for PSU stability, better thermals and lower fan noise.

However, I'd like to keep the max single core performance through turbo boost, so my plan is to disable one core, SMT, and lower the base clock. Now, with turbo boost 2.0 the turbo mode can go beyond all core base and even the TDP so I'm afraid reducing the base clock and disabling a core wont affect max TDP as the other 5 cores will just clock higher until they reach their 5 core turbo speed.

Does anyone have experience underclocking/disabling cores and how that affects turbo speeds and TDP? The Asrock board i'm eying has a setting to put a max to your TDP although its unclear to me if this is system or CPU specific, and whether it actually works.

Much easier to undervolt rather than disabling cores and SMT etc. The net effect of reducing the default voltage by 0.1V is probably just as significant if not more so than disabling a whole core. It's not guaranteed to be stable with a 0.1V undervolt of course, so maybe try 0.05V or 0.075V first and test for stability before going further.

OK. Mr. PixelSquash this is the temps I am getting using handbrake to encode this video on the be quite! loop. I put my 1920x on air because I am running it 24/7 and I don't trust AIOs for that. Currently I am not running the fans on the radiator for the be quiet loop! to their full capacity but I don't see a need to. Unless I go to 5ghz I suppose.

By the time GTX 12xx/etc are out, I expect the gap between the 8700k and 2700x to grow larger in Gaming at 1440/4k, not smaller, in most cases. Exceptions could apply if there are really good advances in high core count optimizations, but it still seems all these years later that max IPC + clock for 4-8 cores beats more cores but lesser IPC+clock. Of course the final thing here is that stock 2700x v stock 8700k the gap is smaller than max Air OC 2700x v 8700k, it just pushes more gaming advantage to 8700k both short and long term.

I am sorry but this is the most BS reason to make a CPU choice and actually ignores everything that pushes new GPU sales. People don't generally get new video cards just to get additional framrates in previous games. People get a video card to best fit their use case. When new games come out and they aren't getting what they want out of their previous card they upgrade. No one is is going to be sitting at 4k screen playing a game comfortably, decide well gosh darn it I am going to get a new card, find out my current game runs faster but not as fast as it could if they got another cpu and feel sad. People get new video cards because a new game is taxing their video card or they are "prepping" for a new game. A CPU outside being patched for something that then kills its performance in an area that matters for a Game will never be worse than it is now in that game. The next game is going to be even more GPU bottlenecked at whatever res you are using than the current one.

That said I am not saying don't get a CPU that excels at gaming if it's your primary or only solution, or if you are on a budget and need to be able to skimp (like getting a 2500k over a 2600k). But people need to be careful about skimping out on everything else in chacing the all elusive FPS, that for outside truly competitive circumstances, or 140hz setups, they are never actually realized and getting something closer to future trends and more professional use might serve them better in the long run.

I’m honestly stunned you were getting such poor performance in FC5 with your TR setup. At that resolution you’re clearly GPU limited, and FC5 is one game that is amazingly optimized. I’ve played this game on a couple systems, 2600K and 5820K, while benchmarking nearly 15 video cards. Even running the game with a HD 7700 with 1GB of vram I barely saw stutters, even at 1080p. The only case where I did, was testing my GTX 590, which can be typical with an older card and SLI.

Having spent time in various PC gaming related networks (reddit, discord, etc.) this actually happens way more often than I'd like to see.

Oh there is a decent sect of people that are like this. Specially in the super high end epeen crowd. I try to lend my advice to one guy like this. But for every 1 of those guys I have 10-15 people that fill a couple other spectrums. But the story is always the same no matter how they got there. They are building for a game coming out, their current game is running like poo, their video card is acting up, they just got a higher res monitor and want something to take better advantage of it.

Reddit and specifically PCMR tend to be a blackhole that brings those people together. But the primary purchasers of even the highend video cards are people looking to improve substandard performance either in current games, or games coming out in the future. Neither of those is going to make 4k any less bottlenecked by the GPU to the point that a current gen CPU from any manufacturer is going perform much differently. In the future who knows, but if both guys are going for more cores for more power, id rather be on that bandwagon, then getting caught out because I could in theory take a game I am running now at 4k and getting disappointed that even though it is running great, but next year when I get new video card, and next years games will run better with that video card I didn't absolutely max out the performance by going with a less capable but faster ST performance CPU. (Terrible terrible run on sentence).

Something the 9900k will have in relation to the 8700k that the 2700x doesn't have on the 2600x is larger L3. The bump from 12->16MB may help quite a lot. My 5960x quite often beats out scores I see from people with 8700k's and it ain't the IPC or quad channel memory. It's the giant fast 20MB L3 cache (overclocked like mad, of course.)
What speed is your cache at and what voltage/mobo are you on,just curious?
