Yeah gotta be careful on temps and volts. If you ever want anything tested on a 9900k just ping me. Mine is daily stable upto 5.2ghz. The only thing I don’t like messing with is ram because this board is horrible at training timings so I leave them alone now that they’re settled. But anything frequency related is fine.
Just doing a real review of the 3800x were its overclocked correctly. It's never going to beat a 5GHz all core 9900k overclock with great RAM like 4000 CL14 but if the 9900k build is 3200 RAM with default timings, the 3800x has the performance. This is great for the price point.
The main weakness of the 3800x is that no matter what you do, you can't increase single thread performance, only multi thread. This allows the 9900k a performance lead in that area. Also because you will never see a 3800x above 4.5GHz all cores, there are limits to multi thread performance. The 9900k ultimately wins because with faster RAM and higher clocks because of better overclocking headroom both on ram and core clocks. It can pass the maximum limitations of the 3800x. Even so this is with very few 9900k builds.
All the reviews say that the 3800x has poor increase in performance over the 3700x. This is not true, with tightening the timing for the RAM and getting a kit rated at 3600. You can reach the performance of some 9900k 5GHz all core overclocked builds with 3200 RAM. At least in the games I have been able to test and in 3d mark. Let face it, the 3800x is not going to beat a correctly overclocked system like yours.
Not bad for a cpu that is approx. £390 on overclockers vs. a cpu that is £500 on overclockers.

What I am saying is that the above two builds are equal. If you overclock the 9900k to 5GHz and also tighten the RAM timings on the 3800x. Remember only 5% of 9900k's get 5GHz all cores and those that do required a 360 AIO minimum to keep temps under control. With the 3800x build because you only overclock with the RAM. There in no increase in temps over stock.
The default RAM for the 9900k is 2666MHz and for the 3800x 3200MHz (AMD recommends 3600 RAM which it gave reviewers). So both systems have overclocked RAM. Keeping the builds under £1000 gives the above two systems.
Note the 3800x build can get an older motherboard and reduce its cost further and still perform normally. I gave the 3800x build a more expensive motherboard to give the 9900k better RAM. Even so the 3800x build has a higher likelihood of overclocking better because RAM overclocking is more consistent.

You really have gone into depth on this 3800x vs 9900k but I wanna ask with aggesa 1.0.0.4 coming and leaks all saying the major changes will you be restarting and looking into then as well?
I know there just leaks at the moment and I highly doubt the bios update would make any real changes but would be nice to know if it does help exp with single or low core count boosting

Good points overall. I'd just say that a master is pretty overkill and you can get something like this and be 100% for VRM's and 2 sticks of ram will tune like mine have 15-16/3600 which is ok. https://www.overclockers.co.uk/giga...cket-1151-ddr4-atx-motherboard-mb-57a-gi.html £169.99 * That's the same board and VRM designs as my Pro wifi board.
The Master has 2 more pcb layers, better vrm design, cooling and some XOC stuff (voltages available in bios). It does better at mem oc'ing but for cpu, hard to spot a difference.

I was going to get a I9 9900k and a gigabyte Z390 Aorus Master , But I think I`m going to wait a bit longer before my next upgrade ( 8 years since my last one ) , and see how the Intel v AMD unfolds .
Same with the x570, it's a lot extra for PCIe 4 but most people could get cheaper. With AMD you could get a B450M Mortar MAX (Socket AM4) DDR4 mATX Motherboard for £92.99 you have support for a 3800x and 3800 RAM. https://asset.msi.com/pdf/main/global/presale_v2/B450M-MORTAR-MAX?
https://www.tomshardware.co.uk/msi-300-400-series-max-motherboards-amd-ryzen-3000,news-61290.html
3900X tested on B450M Mortar. VRM 60c 12 cores on budget motherboard?!? (vs. X570 Taichi)

This would work just as well.

Total: £922.96

Memory overclocking could be limited to approx. 3866/VRM okay for the price. https://youtu.be/v5NDtS8za8g?t=1216

Those are great builds for both systems. That b-die kit will easily run my settings on that board.
My tip would be to get the Alphacool LT360. I have one now. While it doesn't have the bling of RGB (one reason I bought it) with a cooper rad, it's got great performance. Save about 50 on each build also. Get under 900 on either.
Looking like there is a price discount on the 9900k at an easy to imagine place online.
https://www.userbenchmark.com/UserRun/20695517 the oc'd 2080ti is likely throwing the scores up a decent bit.

Could be better to wait for the 9900ks and get that all core boost to 5GHz. Better than trying ones luck with the low percentage chance of getting a 5GHz all core overclock with the 9900k.

From what the rumours I've heard the 9900ks is going to be around £600 , 20% higher than the stock 9900k .
If you have the 9900k you are going to have a motherboard which will overclock it to that anyway so can't see the point of it, if the pricing is true.
I think I'm going to wait until the end of the year, to see about pricing and see what happens with AMDs next gen chips.
Got my case ( Lian li 011 dynamic xl ), going to get the psu and water cooling, waiting for which motherboard and CPU I go for.
I'm on a I7 2600k now so I think I can wait !!!!
the challenges faced by both AMD and Intel on silicon quality mean that good overclocking is only going to be a fairly sure thing if the chip is pre-binned.
The 9900KS and the 3950X will be the state of the art as they will be pre-binned chips at the factory. Like the 8086k is now, they will be worth the money.
Only the top 30% of 9900k chips hit 5ghz at 1.3v that means 70% of the entire production run could not do that.
1.3v is poor and the 9900KS will
need to run at much lower voltage.
Only the top 53% of 3800X chips could hit 4.2ghz at 1.28v that means almost 50% could not hit 4.3 at a decent voltage level.
unless it’s hardwired into a pre built laptop i won’t buy a non pre binned cpu again from either manufacturer.
Once supply improves i would expect AMD to start offering binned Black Editions of their chips but the challenge is that much of the best binned chips are going to the likes of Google.

I'll be curious about these things regarding the 9900ks in stock form:
- what is the uncore set to?
- Any AVX offset?
- LLC defaults?
Those things make a difference in how much voltage is required. There's a massive difference in voltage just based on different LLC levels for example.

will need to wait and see i don’t expect the KS will use an avx offset.

I'm looking to upgrade from my i5 rig; think I'm leaning towards waiting for the 3950 to be released; But pretty sure I'm going Ryzen this time - my last AMD chip was the FX53 - yes, I'm that old.

I think my last AMD computer was a single core CPU running XP

I’m tempted to get a 3800x it’s either that or a 9900k but I’m worried about the x570 mobo fan noise, small fans on a motherboard, you just know they’re gonna wine at some point, or are they quiet?
Don
Been that long eh? I've always used Intel, but never had any bias to any manufacturer, I just choose what's right for me at that time. Same with GPUs.
I just think the 3900 / 3950 are the way to go right now, unless you play to wait for the 4x series.
