the z390 and i7 8790k are rumors, but probable. Whether it will be a higher clocked 6c or a new 8c is unknown too, speculations at best. If AT reviews for the new Ryzen 2 in gaming are not flawed, i think i will upgrade, i am slowly making up my mind ;)

Just keep in mind that the Anandtech review uses 'max officially supported' memory speeds so 2666 for Intel and 2933 for AMD. Nothing wrong with that approach, except that it's not very representative of how most 8700K users will run their CPUs, nor the 2700X for that matter.

If it's gaming performance you are after, I still think the '8790K' ;) will probably be worth waiting for before deciding. The 8700K isn't that much of an upgrade over a 4770K for gaming, and Ryzen even less so, in fact it's probably a side grade as far as gaming is concerned.

From Computerbase's review, there seems to be a 25-100MHz difference between P95 all core clocks between a Noctua NH-U14S and the respective stock coolers these CPUs ship with. However the temperature you can drop with a good aftermarket cooler is 15-22 degrees. Wraith Spire isn't the optimal cooler for the the 2600X, when compared to the others.

side grade probably, but chipset features i take into consideration too. like usb3.1 and the ability to boot from pcie nvme ssd. Maybe i wait a few months maybe i don't ;)

Now that reviews are out, that has proven to be untrue, they are both 'toasty' CPUs when overclocked, with the 2700X @ 4.2GHz/1.4V actually drawing significantly more power than the 8700K @ 4.9GHz/1.4V, using Cinebench MT as an example we are looking at 141W for the 8700 OC vs 191W for the 2700X OC https://www.gamersnexus.net/hwreviews/3287-amd-r7-2700-and-2700x-review-game-streaming-cpu-benchmarks-memory/page-3

Of course, the 2700X is also significantly faster than a 8700K at Cinebench MT, but its efficiency is most definitely not better when both are overclocked.
AT said they got theirs up to 4.35 and I thought the vcore was 1.35, but I can't find it now. I will have a working system sometime about May 1st (motherboard ships next Thursday). I will see if I can duplicate that. I wish they would have listed the vcore. And one site claiming its more inefficient is not enough for me, all reviews have flaws. So let wait and see the general consensus.

What exactly is a 8790K? Is that just a higher clocked 8700K? Or do you mean the supposed upcoming 8C/16T CPU from Intel?

The 2700X is now a known quantity, the '8790K' is not. But if its still 6C/12T like the 8700K, then it still won't beat the 2700X in most MT applications. If its 8C/16T then that is a whole new ballgame, as Intel has the IPC and clockspeed advantage, and at core parity would most likely come out ahead (think 8700K vs 2600X)
This mystical 8790k would almost certainly outperform the 2700x if it is 8c, but the price of it would be quite a bit higher imo.

Ended up with an Asus X470-Pro board, as Micro Center had that and the Asus X470-F Gaming. :confused2: Was hoping there was going to be a better board selection. Going with the included cooler first, but may try an H110 later.

It's not just one review, many reviews show that it draws more power than an 1800X, The Stilts testing also shows this, with the 2700X drawing over 140W at stock.

It looks like AMD is running the Ryzen 2000 chips at close to their limits already, which explains why the efficiency is actually worse than previous gen Ryzens. If you actually undervolt Ryzen 2000 chips and run them at say, 4GHz rather than 4.2 they are much more efficient, but efficiency goes out the window when trying to get those last few hundred MHz

A 2700X at stock is clocked higher than an 1800X at stock. I wouldn't be surprised that it used more power.

You can use as little as 1.15V to maintain 4GHz all core on the 2700X. So it's pretty clear AMD chose performance over power efficiency (as reflected in higher published TDP and extra boost TDP).

I'm fine with that as it looks like a manual OC is not needed. Simply configure the motherboard to allow higher boost limits if you want max performance and let it do its thing. Or limit to 95W or lower for better efficiency (better than Coffee Lake, even).

Just received my 2700x and was able to go home from work over the lunch hour and install it in my Crosshair VI Hero rig below.

I kept it stock and my memory (Flare-X 3200) to the 3200 mark with dram vcore at 1.38. I was also running memory at 3200 for the 1800x at 4 Ghz

CPU is very smooth and slightly faster than my 1800x which I OC'd to 4GHZ on all 8 cores
For Cinebench R15 the 1800x scored @ 1760 while the 2700x stock scored 1792.

Aida64 Queen 1800x=92300 while the 2700x stock was 93300.

I will run more test tonight.

I am using the 6004 BIOS from Asus officially posted on their website today for my mb.

So a stock 2700X beats a tuned/max OC 1800X. Not bad.

I see that water block in your sig - interested to see if the excess cooling capacity results in higher boost (you might need to up power limits in BIOS if it supports it to see full effect).

Just ordered a 2700X after selling my 1700 to a friend of mine for his new build. I already have a Noctua U14S cooler so he'll be getting the Prism as well.

So far the only tests I've seen with X370 boards have been the C6H. Can anyone point me to some 2700X testing done on the Taichi? Will it even matter?

So speaking of the new Ryzen CPUs and x470 chipset, has anyone tried running Linux on them?

I'm curious about something.

I don't have a 4770k but I do have a 3570k with DDR3-1600 from 2012. I upgraded to Ryzen and noticed a 20-35% performance upgrade from ivybridge with same video card.

Wasn't Haswell just a 5-7% upgrade over ivybridge?

Or was it 12 threads vs 4 threads that gave me a boost?

Would be the extra threads that gave the most benefit, plus slightly better IPC and also DDR4 makes an impact.

A while back I upgraded a 2500K to a 3770K, so slight IPC bump as well, but the extra threads made all the difference in games like BF1, went from unplayable* to playable pretty much. A pretty similar increase to your Ryzen upgrade I would say.

*slight exaggeration, it was playable but fps dips down to ~30 aren't fun.

Maybe this chart will explain better what I meant by the 'sidegrade' comment re: the 4770K. Also note where the 3570K is placed in the charts... definitely starting to show its age here.

IEC, the 2700x runs great at stock. I enabled Stilt's 3200 safe memory settings (a preset in the Asus CH6H BIOS 6004}. Runs smooth.

So I ended up getting the Gigabyte Gaming 7 Wi-Fi Mobo after all. I tried my darndest to come up with the extra cash to get the X470 Taichi Ultimate, but I guess it wasn't meant to be. I am surprised I was even able to purchase a motherboard at all due to stock being sold out, then put on back order, then back to sold out and every time a motherboard would come back into stock I would try to as quickly as possible make the purchase but newegg wouldn't take my payment..o_O Soon as I got to the select payment option all payment options would be greyed out. Well right up till after midnight last night that is. What a nightmare that was!! Luckily though its all over and I got me a mobo and 2700x combo.Should be getting it by Wed. if all goes as planned.

My 2700x came today. I'm running it with the Wraith Prism on an Asrock AB350M Pro 4 motherboard.

I did a quickie Pstate setup with only the top speed altered to 4GHz @ 1.20Vcore. Memory is Flare X 3200 with 4 tweaks beyond the XMP profile.

Temps are about 14C higher than my 1600/Cryorig H7 setup under the same load (but running 8 threads vs 6).

I'll do some additional tweaking of voltage and memory but I doubt I'll be able to get the temps and noise down near my normal cool & quiet preference.

I'll probably be buying a Be Quiet! Dark Rock 4 in the coming weeks. I suspect I can get temps and noise down quite a bit with that.

Edit: My 2700X seems stable at 4GHz @ 1.125vcore. It's now 4C cooler under load, only 10C above the 1600/H7 combo. Still leaning toward the Dark Rock though.

Geekbench 4.22 with SMT on: https://browser.geekbench.com/v4/cpu/8014257

Edit2: Geekbench 4.22 test at 4.2 GHz with SMT off: https://browser.geekbench.com/v4/cpu/8017696

@The Stilt , do you have safe 2700x settings for 3600 cas 15 samsung b-die ?
The parameters really don't change that much within the same IC.

3600C15 is the highest B-die bin available, so you can throw pretty much anything at them.

These are pretty close to the max on Pinnacle:

1.05 - 1.100V SoC voltage and 1.375 - 1.400V memory voltage should do.
GearDownMode might have to be enabled on some boards, but generally disabled should work just fine.
Some boards X470 boards also prefer 48Ohm ProcODT instead of the 60Ohm or 53.3Ohm.
Also you might want to reduce CLKDrvStrength from 24Ohm to 20Ohm, as some CPUs like it while the others don't.

Just installed my 2700X into an Asrock X370 Taichi flashed to latest 4.60 BIOS. The boost is not working particularly well on this board at this point. Loading up one thread I really only see it go up to 4.25 GHz, rarely at that, and it usually stays in the 4.1-4.15 range. With one core loaded it's at 42C and well under the PPT, EDC and TDC power limits in Ryzen master. Not sure how to make it go to 4.3-4.35 like it's supposed to, I haven't seen it hit those numbers even once under light one thread load.

I even manually plugged in the precision boost overdrive limits from the_stilt's mini review (1000W, 114A/168A TDC/EDC limits).

Anyone have any suggestions or am I stuck buying X470?
