AMD Ryzen 9 3900X

[Parn]

The model that interests me the most is the R7 3700X, plenty of cores, high performance and 65W TDP at Core i5 price.

Hey there,
I want to ask if TechPowerUp has that scene that they light baked in unreal for doing this benchmark and the program that was used to compile inside VS 2019.
I would like to have them so I can do my own benchmark and compare. Could you possibly provide a link?

I would still like to see Windows 10 1809 vs 1903 performance. I can't find it anywhere yet with the new Ryzen CPUs

 

[Metroid]

I have watched this review today

from gamer nexus and on the 3900x smt off was much much better off, on the 3600x in some cases smt off was better, this might be related to the scheduler on windows 1903, probably there is a problem with more than 8 cores or more than 16 threads on it, however the lows when smt was off is also affected by the smt off, so all in all, that review is a very good watch if you plan to use the 3900x for gaming. He did not test many single thread apps with smt off so we dont know if that might play the right card in the deck.

Yes I subscribe to Gamers Nexus. Steve is awesome, I saw that review. I also emailed him directly waiting for a reply to see if he will show win 10 1809 / 1903 differences.

So temps are holding it back for OCing...
Gamers Nexus showed that disabling SMT can significantly increase gaming results as it then allowed higher OC's (4.4GHz all).

I'm surprised Wizzard didn't think of trying such things. (Or maybe just had no time)

I'd be interested in seeing another look at the 3900X but this time looking at results both stock and OC with SMT disabled, as well as one where you disable 4 cores to effectively make it a 3800X.
Then test again with and without SMT.

If 3900X is held back by temps so much in gaming, the results of the above would be very enlightening for those wanting to focus more on gaming with Zen2.

I have a feeling the 3800X when benchmarks go live will be AMD's best gaming CPU out of the box.

smt off used to be good for intel back in 2009 on the i7 9xx series 4 cores 8 threads, seems like amd might have the same problem with this but on lower end models I think will be less, for example if you see the gamers nexus 3600 review, you will see that leaving it at stock and smt on is the best approach but that does not hold true for the 3900x and that migt be related like is aid before to the scheduler, windows xp and windows 7 was really bad handling smt back in 2009 for intel cpus.

AMD Ryzen 5 3600 CPU Review & Benchmarks: Strong Recommendation from GN | GamersNexus

stub Alongside the 3900X and 3700X that we’re also reviewing, AMD launched its R5 3600 today to the public. We got a production sample of one of the R5 3600 CPUs through a third-party and, after seeing its performance, we wanted to focus first on this one for our initial Ryzen 3000 review. We’ve...

www.gamersnexus.net

The only thing I would like him to do is power consumption while smt is off and undervolting the voltage while keep stock frequency and do some tests.

 

[Xzibit]

Didn't you need the latest chipset drivers to complete the scheduling update ?

 

[brendonmc]

AMD gave us:
1Ghz CPUs
64bit CPUs
Multicore CPUs
On-die Memory Controllers
8 Core CPUs

Therefore...
If it wasn't for AMD, CPUs probably would still be be:
slow
32 bit
single core
expensive

OMG. Its a great time to be alive!

What's up with some of the benchmarks? Like for instance in Wolfenstein2 at 1440p https://tpucdn.com/review/amd-ryzen-9-3900x/images/wolfenstein-ii-2560-1440.png the 2700x is faster than the 8700k and the 9900k!! Yet when we saw the benchmarks at the 2700x launch it was slower

https://tpucdn.com/review/amd-ryzen-7-2700x/images/wolfenstein-ii_2560_1440.png

What gives?

 

[pantherx12]

Just popping by to say these are super exciting times. Can't wait to see the 16 core part results.

Shame frequency uplift is lower than expected but great results none the less.

Anyone is very welcome to buy me this as a gift.

smt off used to be good for intel back in 2009 on the i7 9xx series 4 cores 8 threads, seems like amd might have the same problem with this

Look at the Anandtech article. i7 9700K and i9-9900k. i9 has all the advantages (slightly higher clock and L3 cache) and still in some benchmarks (Gimp, Webtests, Photoscan, Ice Storm) the i7 scores better than the i9 because of no static partitioning and the highly single threaded nature of the tests (and no effect of 100 MHz more clock/ 4MB more L3 cache). So it's a general SMT/HT thing in some benchmarks and not something specific to AMD. Just that with AMD you get SMT nearly everywhere and with Intel its only on the largest and smallest SKUs for a few generations on desktop. So you don't buy an i9 and disable HT, because then you could just buy the i7. And you don't buy a Pentium and disable HT, because that would just suck. Since you can't get a 6C/6T CPU (or 8/8) out of the box for AMD, it makes sense to test it for some scenarios.

That value goes into nothing if you buy a expensive 570x

X570 boards are priced from $200 to $1000 with many choices in between. Not only that but with BIOS updates you can use any Ryzen board. I even saw a video yesterday that a B350 with a weak VRM works with the 3900X.

It works, but it throttled, remember.
If you are going to run a 3900x or 3950x, I would certainly stick with X570 or a robust X470 board. The VRMs on chipsets below that may not support it well.

I know I was just replying to the post making it seem like you need an X570 board for 3900X. For me all of my X470 boards are fine. I might even build a PC with one of these new chips but Threadripper is coming!!!!!

 

[Deathy]

X570 boards are priced from $200

Make that below $150 once prices have settled (cheapest AsRock X570 is at $155 on Newegg right now, 145 after rebate and that site sucks). And that is still a 4 phase with doublers. And even many decent B450 motherboards will handle the 12 core. It really depends if you want to go t o 1.4V or 1.5V watercooling overclocking (not to mention LN2, which is mostly out of the question on most things not X570). But stock, the 12 core isn't that enormous. That said, the 3xx boards were universally very sketchy and I wouldn't trust them with anything above 8 cores and even the 8 core I wouldn't OC by a lot. 6 cores and below: throw it on a potatoe and max everything.

Choose your board wisely.

Ok I have the following boards and I am confident they will work.

Asus X470 Prime
As rock X470 Master
As ROck X470 Taichi
Gigabyte X470 Gaming 7

I am a bit confused about the chart stating that the 3950 will not work with some boards in the X470 lineup including a couple that I have mentioned that have up to 2 8 PIN CPU and 12 phases.

Now when we all have seen the rewievs, and intel is still the king of gaming and super beats 5700/5700x.
i rest my case.

Clearly that list is not The Gospel. That said, just because it has 2 8-pins and 12 phases doesn't mean it can support it. Not all phases/VRM bits are created equal. Most 12 phase are doubled, not true 12.

You are obviously a fan of Intel and there is nothing wrong with that. However making statements like the Super is 9 to 10% faster than the 5700/5700XT but they cost significantly less. You won't know this but AMD GPUs age much better than their NVdia counterparts. As far as gaming goes I suggest you watch the Tech Deals review of the 3600X vs the 8700K.

 

[EarthDog]

but AMD GPUs age much better than their NVdia counterparts.

Fine wine isn't sour grapes, but can't say they age "much" better. A couple of places did articles covering that. A couple percent here or there is nothing. That shouldn't be a consideration honestly.

However making statements like the Super is 9 to 10% faster than the 5700/5700XT but they cost significantly less.

That statement is true. Its notably faster, but the xt costs less (uses more power and is louder in its current form). Once AIB versions come out, that lead will be cut in half, prices will go up, noise will go down.

 

[W1zzard]

What gives?

Maybe Intel CPU security patches, or Windows 10 scheduler, or Wolfenstein game patches, or graphics driver

MP3 encoding can be run in multithreaded mode, if running batch conversion in Foobar2000, fyi

Encoding multiple MP3s at the same time, that's not multithreaded. By that same logic you can parallelize anything by running multiple instances in parallel that don't share anything.
