3700X vs 3800X

Don't know if the OP saw SiliconLottery's post yesterday, but they noticed a 100Mhz+ difference between the 3700X and 3800X on all-core clocks.
Whether that's worth $70 to you is a personal decision.

There is absolutely a difference in silicon quality between the 3700X and 3800X, to get that out of the way. On average, the 3800X will hit about 100MHz or more higher all core. I know a lot of people have been wanting some kind of confirmation on this. We won't have statistics up right at launch as our sample size is still a bit small (a bit of trouble getting these CPUs right now), but they should be posted within a couple weeks.

This is what i've seen. Without touching anything my 3800x has no problem hitting 4250mhz, and if I had lower ambient temps (80f ambient currently) or a custom setup I believe I could hit 4300mhz all core (Or higher) no problem.

Interesting how its pretty much exact same clocks as our 2700x (even though its advertised as higher clocks right?)

With the same setup the 2700x would clock a little less, and use way more power. I was 4100-4200 w/ PBO enabled on my 2700x, which was about 130w draw versus the 95w of the 3800x. Single core for the 2700x was only 4300 at best as well.

The 3800x gets a little higher clocks without me even having to touch anything.

Oh i wasn't commenting on the performance / efficiency's since its well agreed the new 7nm chips are worth there weight in gold. It just seems like most people are reporting lower than advertised clocks

I mean, i'm getting 4250mhz all core on my 3800x without touching a thing, and 4.4ghz ST. That's pretty good.

I think the disapointment is overclocking doing nothing. People expected it to be like last gen where you'd get another 200-300mhz. Unfortunately, because of the 7nm process, these things are maxed out once you hit 95w.

That and AMD is maximizing the performance of the individual CPU's with PBO, and changed the marketing where they are now displaying the maximum. The headroom is now marginal, whereas previous generations, they set it to the lowest common speed because they didn't have PBO, dynamic voltages in MB.

This will continue to be the trend, the day's of the I5 2500K or the Athlon 2500+ where you could get 70%-80% more out the silicon are gone. Out of the factory, they can bin the CPU's to see their performance.

We just have to set our expectations accordingly.
 
I finally opened and setup the combo. Overclocking is a failure, at least on my combo. Didn't change anything and set the multiplier to 40 resulted in a Windows crash upon running AID64's test. I thought it's advertised to reach 4.4Ghz, but can't even reach 4Ghz? What a disappointment! I'm not much an Ocer, so tell what I've done wrong.

What you've done wrong is bothering to overclock this thing manually to begin with. There is no benefit of doing so, for the most part.

It really hasn't changed that much from 2000 series Ryzen. OC'ing 2700X was pointless.

Well, the 2700x you could at least get more out of by enabling PBO and removing the EDC limits, in particular.

With these new chips they don't draw the power needed where removing the stock limits does anything.

On my (old) 3700x I got the same results with just enabling PBO and setting it to “motherboard” performance limit on stock cooler. 3800x is a waste of money IMHO. Manual overclock will limit single core boost.
 
From most of the reviews, I'm not sure the 3800x is really warranted. It mostly performs like a 3700x, but then again out of the box it is slightly faster. Whether that smaller performance difference is worth the $70 cost difference is honestly up to you to decide, but I personally would save the $$$ and put it towards something more useful.

I too am consistently running at 4250 all core on my 3700x in typical loads (high refresh gaming. On the other hand, it takes above 1.4V+ for me to sustain 4300 manual. 3800x is clearly better binned, but the difference is so ridiculous IMO they shouldn't even have made a 3700x and 3800x should be $329.

Boosts are another thing, I can game for hours and none of my max clocks will have gone over 4300... This is with PBO on and set to +200 too.... zzzzz

With default settings w/ my 3800x I hit 4400-4500 in most games, unless it's actually all core in which case i'm 4300.

The price differential for the 3800x is worth it IMO if you are chasing higher clocks. It's clearly binned better.

Surely is better binned, the results on silicon lottery make that very clear. They'll do 4.3ghz at much lower vcore.

Get this lol.. if I switch my power plan from AMD Performance over to AMD power saver, my all core becomes 4300 (still drops to 4216 if I load the temps up in AIDA64). Been playing Far Cry 5 for the past half hour with all cores locked in at 4300 almost all the time. Still not getting any single core boost at all.. So my chip can game with all 8 cores at 4300mhz but can't even boost a single core to the box rated 4400?

I would really hope boost starts working better in the near term. That +200 they talked about in the video from AMD would be nice. If your 3800x started running all cores at 4300 and boosting a core or two to 4600-4700, that would certainly be cool. Just had a guy in another thread showing me his 3600x hitting 4550 boosts on an x470 board.. so what gives here?

Bios and setup and hardware. People with shit sorted and time tweaking on good cooler are hitting 4.5-4.6.

The ' default setting Joe's' are not.

I think a HUGE portion of this is BIOS related. People like me stuck on 1.0.0.2 can barely get anything approaching rock solid stability.


I am having issues with even my 3000c15 kit. It will run AIDA64 or Prime 95 stress test for 2 hours just fine, and then a hard restart or black flashing screen. Temps are fine and I cannot seem to find a specific error.

It has been nearly 5 weeks since Asus has given us a bios update on a 15 month old Mobo. I could understand if it were a bottom barrel A320 or B350 board, but it isn't.

I am strongly considering replacing the Mobo, since I do not want to rebuild my loop and Asus Never fix their crap or even wait 6 more weeks for a bios update.


I have tried 2 different ram kits with different ICs and cannot get anything stable. AMD claims Zen2 can run 2 Dual rank DIMMs at 3200. I cannot get either kit stable at their rated 3000/3200.

What's crazy is that I have a decent 3700x whcih just has a wraith prism on it. I need to get it underwater but do not want to tear down my loop again only to replace the mobo. It's a really PITA when you have dual rads and on is horizontal and the other vertical.
 
Finally after exactly 15 days of waiting, (Microcenter's Return policy on CPUs) I spotted 10+ quantity of 3900x and went to exchange my 3700x for a 3900x! I'm a happy camper now. Couldn't believe they would be OOS for that long as I almost missed the window of their return/exchange policy. Whew!!!

Glad to hear it. I forgot to update my post, but I have a 32GB dual rank B die 3000c14 kit running rock solid @ 3400 14-14-14-28-1t..3600 seemed stable, it passed 6 hours of handbrake encoding and 5 hours of real bench but it was hot here during the weekend and my fans kept ramping up and down nonstop so I couldn't let it run longer to be 100% sure.


Working on my loop now do hopefully will have it under water tonight.
 
The more I think about it, the more the 3900x makes sense. One day maybe
 
If all you do is gaming, I think it's largely a waste of $100 over the 3800x, or $160 over the 3700x.

Maybe down the road if games can really make use of more than 8 cores it'll be worth it, but by then you'll be able to get one at a substantial discount and drop it in if you even need it, or AM4 will be long dead anyways.
 
If all I did was game, I'd probably go with the 3600x, but this box may need to step up it's duties as one of my Threadripper boxes is probably going to be sold
 
the 3700x demo PC at Marietta, GA microcenter was hitting 203 single thread in Cinebench. I checked their overclock settings and they are not even using PBO just PB2 aka Auto-Overclocking in bios and 3600mhz ram at tweaked settings.

So the 3700x is beast mode if you ask me. I do not think it is worth 70 more for the 3800x to be honest. I think you are wasting your hard earned monies.

I wouldn't, because the X is only worth 200 more mhz boost which is nothing but a benchmark queen or another 5 or so FPS in games. To be honest I have both 3900x which hits 4550 using PBO and 4070 all core on avg sometimes 4200 all core on lighter loads and my 3600(non X) hits 4200 as well single thread and can maintain it for long durations. I think unless you are just wanting the X letter for another $50+ dollars then by all means but there is ZILCH difference in gaming performance between the two.

There is no difference between the 3600 and the 3900x in gaming either if you ask me. I mean sure synthetics are going to show higher FPS between the two but real life experience you will notice literally nothing!

I urge you to consider spending the extra money on faster ram. It is proven that ram latencies absolutely matter with Zen 2 cores. For instance my 3200 cl 14 with custom timings on my 3600 delivers 75ns final latency.

My 3900x with Dominator Platinum B Die 3600mhz @ CL 14 custom timings as a 67ns natural latency and I get much higher bandwidth and much higher synthetic performance.

I would throw dominator on my 3600 as well but I do not want to spend the money on something that wont make a perceivable difference.

edit** however, since you mention productivity over gaming I would definitely consider not getting the X and instead getting 3600mhz ram and tweaking timings. Its never been easier using the Ryzen Ram Calculator app. Just put in the exact settings they tell you to and your off the super high performance races. The guy that makes that app seriously knows his shit when it comes to ram timings. He has written many very detailed guides as well across the internets.

For instance the difference in 3600 XMP and 3600 tweaked timings on my 3900x is a whopping 5 to 10 FPS in h265 encoding over the course of hours. This makes a huge impact in the time I have to wait for encoding projects to complete. For productivity RAM matters.

This has been tested and shown to be wrong- however, the difference is small. Between 3700X and 3900X? That should be negligible.

They don't seem to have a 3900 non x out at the moment, and yes, ram will be upgraded as I have seen the threads.

Wrong? I mean maybe by your own metric, possibly. I mean If that is the case, then I say spelling Color as Colour is wrong but the Brits will argue with me all day.

Point being you know the difference between Color and Colour is so negligible because there is a one letter difference but the experience and meaning is the same by our understanding and perception.

Thus, 120fps on the 3600x vs 115 fps on the 3600 is imperceptible but the game is still just as enjoyable and you save X number of dollars by not paying for the X.

This is only in the case of the 3600. When we are talking abut 3600x vs 3700x thats a whole 'nuther ball game.

3700x to 3900x in gaming should have such a small difference you would only notice the differences quantitatively and certainly not qualitatively. However in productivity I bargain the difference is very big because were talking about not only 8 more threads but double the cache due to having two CCXs, but this is getting off topic.

Yeah I'd use the $50 to get a b die kit or other high speed kit, or if I were already planning on b die, I would use the $50 toward a GPU upgrade.

Failing that, one could use the $50 for a nice AIO to keep your CPU boosting for as long as possible while being quieter then the stock wraith prism will offer.


The 3600s are a fantastic value...I only went with a 3700x since I was already on a 2700 and managed to sell it for $85% of what I paid for it before the leaks started pushing the channel inventory down to nothing. I think it cost me $75 ish to upgrade to a 3700x. Well worth the money IMO but I wanted something new to tinker with!

3700x is an absolute monster cpu. In fact I am going to be selling my 3600 tomorrow or the next day to get a 3700x instead because I want the extra 2 cores for no reason other than im a power junky.

16 core 32 thread monster
next month.

Yeah, we seem to recall those coming down the line
 
That is true its possible there will be a new board. (1)

I don't know I am just having a hard time justifying buying anything over the 3600 (2)

1) yes there will prob be new socket coming out as DDR5 is on the way https://hardforum.com/threads/micron-has-ddr5-in-the-works.1984048/

2) why would you want a 6 core when next year all the new consoles will 8 core Zen chips in them? look for that to be in the system requirements for upcoming games in 2020 and beyond.

** if you're a gamer and building a new rig i would do nothing less than 8 cores, period.
 
I bought the 3700x, but box still unopened. I want to wait until Wednesday too see if MC has any 3900x in.

You can still return or exchange open box cpu at MC. Just make sure to clean it up with no bent pins.

I own the 3900x

I was making a statement that the 8 core cpus are really powerful

Thanks for your unnecessary sarcasm.

But you show me anywhere you can get a 8 core with that much production power for that measly price.

There's a guy in the FS/FT area selling his 3700X at SRP shipped so no tax... already a good deal imo
