God damn it give me that sweet sweet Threadripper Gen 3 AMD!!

Amazing IPC for productivity, Amazing core count and Amazing Gaming performance.

Feels it is back to Athlon64 days.




Good.

Not quite but I get what you are trying to say, Athlon fx were far superior to intel netburst than ryzen 3xxx is to 9900k. Newegg sold them pretty fast. I had some problems so I could not buy it, now i will have to wait be back in stock. After seen many reviews I must admit that the 3700x is the best choice here, before the reviews i thought the 3900x would be but for the price the 3700x is much more efficient and plus with the money $170 or so saved on the 3700x over the 3900x can be used to buy a better cpu in 2 years, maybe intel 10nm, intel 7nm or ryzen 4xxx series.

That wraith prism cooler will be enough for the 3700x, if going 3900x then a better cooler will be needed, watercooling is a must and watercooling is expensive and cost money to be kept and not to mention is kind risk if somehow something is messed up. I had watercooling for years and never had a problem but I used to keep watching it regularly, with air cooling you just leave there and forget.

any idea?

I would expect to see performance improvements, if only small ones, over time.
ASRock already has two new UEFI versions for the boards that @W1zzard tested with and one of them is supposed to improve the performance for the 3900X specifically.

CPU-z reports 2 volts on X470.

 

[W1zzard]

CPU-z reports 2 volts on X470.

Might even be 2 V, I did see some high voltages, too, depending on the board/bios/setting. Always a good idea to actually measure the voltage

Yo Intel, you remember that gaming dominance you had left?

Its gone.

This is one killer CPU

 

[kanecvr]

thought you were talking smack at first so I just checked, confirmed... it is 57 at load for 9900k... something has to be wrong there

my 9700k would hit 95 celsius on a NH-D14 with a 5ghz even OC... lol


future games might utilize more cores. and most CPU purchases are long term purchases for people... my 2500k for example lasted me 7 years.

Yup. I get 81C with the Noctula NH-D14 but I noticed my motherboard applies an all core boost of 4.8 GHz under load. I'm using a borrowed Asus z370 rog strix. The lowest it will go is 78C using my Thermaright "Le Grande Macho", but if I bump it up to 5GHz it breaks 85C even with that monstrosity of a cooler. And these results are obtained using an open air test bench, in an air conditioned room (25-26C ambient).

New ryzens are pretty hot too apparently....

I have been hearing that hypothetical for 15 years.

plenty of games benefit from 6 core cpu's now. not sure what ya smokin. look at benches, 8700k decimates everything when it launched. but yeah we have awhile to wait before more than 6 cores matters.

 

[Xuper]

With 7nm or 5nm , I expect normal temp would be 70 or above.

Has any review site, even one, tested with all of the Intel-only security flaws mitigated? (Note: This includes turning off hyperthreading.)

Has any review site, even one, done that and showed the data for them on and off?

Anandtech explicitly said it did not use the mitigations. Other reviews I've seen don't even mention that they exist. Contrary to what one poster said in another thread, using 1903 does not mean they flaws are mitigated. Microsoft chose to make at least one optional (I don't recall how many are optional), a matter of users manually finding and installing the mitigations — apparently to sacrifice security for performance on Intel. There is also the matter of disabling hyperthreading.

the glue is working for amd; now only the prices should go lower

 

[Eskimonster]

And the king is still 9700k/9900k, you can pick the one you prefer even.

Even Steve says intel is for gaming.

Phoronix did its tests with all default mitigations turned on. That's probably why the 3900x is trading blows with the i9 7960x.

That's what I expected, since Phoronix seems to be a no-nonsense site. So, my question should be revised:

Has any review site that is testing with Windows, especially a site that is testing a lot of video games, shown the necessary data?

edit: Default mitigations in Windows, as I believe I mentioned, also don't really cut the mustard. I read that MS has made some of them (at least one of them... I don't recall how many) manual installs, apparently to sacrifice security for performance on Intel. There is also the matter of disabling hyperthreading. Default mitigations in Linux, though, might be a bit more comprehensive. I do know that the OpenBSD team disabled hyperthreading and is not the only group of experts to argue that that must be done for full security.

Nah, the same was said of X99 requiring water cooling, hot chip, even hotter when overclocking. My OC'd 5820K @4.4GHz is absolutely fine with an NH D15. If the 3900x comes with AMD's standard air cooler than an NH D15 is going to be more than sufficient.

I think that might be a little bit much since most of these "vulnerabilities" have only been PoCs and that actually using most of these mitigations (with the exception of a few like Meltdown,) can't be easily or usefully exploited. Most of the spectre variants literally require the stars to align to be useful for malicious intent. To makes matters worse a lot of these "vulnerabilities" require root access to the machine (which if malware already has that, you're already screwed and they don't need these vulnerabilities.) Most of these mitigations are for the case if you're running in a VM because it could possibly* let you access host memory. For the average user though, most of these mitigations mean nothing.

So, with all due respect, I don't think there is value to doing it. It means something for people writing server applications running in a virtualized environment, not for consumers playing games and browsing the web.

If you don't believe me, then I highly suggest you try to find even one piece of software that's not a PoC showing real world usage of spectre. Then you'll find out real quickly why people (consumers,) shouldn't care.

*: Odds of this are still extremely low.

B350 paired with a 3900X

B350 paired with a 3900X

So It worked? maybe down clock to 4ghz.

I usually recommend people waiting a little bit before investing in a brand new platform. Not only are prices usually inflated at launch, but it's also wise to look for good reviews of the specific motherboards you're interested in, and of course wait for the usual BIOS issues and software bugs to be resolved.
E.g., if I were to replace my primary machine, and probably invest $1000 or more, I would wait 1-2 months. I don't pay top dollar and then waste my time doing "beta testing".

Also, Linux users should be aware of the booting issues described here, the link also mentions how to work around it temporarily.

Even Steve says intel is for gaming.

You think? I would much prefer a gaming CPU chugging along at 65-75C than this 8700K that runs into 80+ without even stretching its legs. Let alone a 9900K that will readily push into 100C unless you put a massive heatsink on top. I'll take the minor average FPS gap... because those minimums are just about the same now, and that's where its really at.

Steve might have missed some considerations here I would say. We buy Nvidia GPUs because of performance but also low noise/heat, but we are happy with a top end Intel CPU that can boil water? For what, 5%? That time has passed, seriously. These new Zen chips can get along just fine across the board, and its a clear departure from the previous gen, which was also a bit better than the first. These CPUs are now just fine even for high refresh.

Look at those charts and the actual differences, I mean yes, Steve puts them in some order of performance, but really? Its convincingly samey across the board with a 9900K *with OC*. That is a 200-400 mhz clock speed gap and still Ryzen keeps up.

Now consider the fact that a 9900K cannot even sustain its specced turbo within its stated TDP, as well. A clear change from the Intel norm, despite the fine print under Turbo.

Apparently, there have been some bios improvements that significantly change boost behavior:

The AMD 3rd Gen Ryzen Deep Dive Review: 3700X and 3900X Raising The Bar

As far as I have seen, TechPowerUP's 3900X already boosted up to 4.6 GHz - is this motherboard specific? Was X570 Taichi already performing up to specifications?

 

[ZenZimZaliben]

Good review. And good job AMD. The chip is very nice but even better for competition and keeping intel some what in check. All the haters need to rethink their position. This is a win for everyone whether you favor intel or amd. Strong competition means the consumers have choice and choice means price wars.

He (AnandTech) didn't check for BIOS updates before he did the testing. The new BIOS was ready on the 2nd of July, not the 7th as he claims. Anyway he will re-run the tests. As for the Taichi I'm not sure if the version 1.40 that Enhances Ryzen CPU performance for the Extreme X570 is already in the used version 1.30 for Taichi. Time will tell I guess. I couldn't find a 1.40 for Taichi, maybe @W1zzard can?
