AMD Ryzen 9 3900X and Ryzen 7 3700X

[Korrorra]

Not impressed. The 9900K still kicks the crap out of these new chips. Kind of feels like they renamed the 2000 series and did a boost clock and core count. The memory latency alone is bad. Wait for a price drop and then the new chips will be worth it. Now some people are saying they cant get advertised speeds because a ufei bug. All these test are moot then. I'll wait for the "revised scores" that will have a magical boost.

I really don't get the advertised clock speeds. I haven't seen a single 3900x hit its advertised clock speed of 4.6ghz.

What are you smoking?

I'm gonna wait for 3800x reviews to appear, the extra 60-odd quid might be worth it for the better frequencies longterm (since it seems it might not be possible to OC a 3700x up to 3800x speeds).

well, that and waiting for my x370 board to get the bios update to support it :-)

Interesting results - personally for me, as someone who wouldn't ordinarily ever consider going the AMD route..it may be an option if Intel don't pull their finger out and either drop the prices of the 9900k further, or release something new.
For gaming, we're now seeing near enough parity on the top end consumer intel and AMD chips (even in games which have an Intel bias), and the 9900k & 3900X are near enough identical price wise at £475 (intel) £480 (AMD). IF you need lots of threads them AMD continue to take the crown in many cases, but then 90% of us don't

I won't be upgrading until August/September now, so will be keeping an eye on the prices. Could be time for my first AMD chip in 20 years...

The interesting thing is testing gaming results, with something else going at the same time. The AMD copes with that much much better than the Intel, thanks to the extra cores. Definitely food for thought.

Not in a major hurry to upgrade from my 1700 just yet, so I'm happy to wait on some price drops. Want to see how the 3800X benchmarks also.

As I'm not earning at the moment - doing solo indie game dev - I'm having to wait before I upgrade my old i5 4670K. To see these leaps and bounds from AMD makes me very happy indeed, they're really pushing intel hard right now. Reminds me of the old Althon days - that competition led directly to the Core series from Intel.

As a content creator who games and isn't on a wage right now, the Bang4Buck, multithreaded and single-core performance all matter a lot to me. AMD right now are slaying it. Great to see.

Good times for consumers await.

Now, the one thing that I'm missing in this review is how the 3700X and the 3900X do in a X470 board. Still not quite sold on the X570 chipset, even though prices aren't as eyewateringly high as expected. If nothing else, the X470 is a tried-and-true platform at this point.

EDIT: Seems TechPowerUp has what I'm looking for. Looks very promising.

At work we have a machine with a B350 motherboard which I suspect would benefit a lot from an upgrade, would be nice to know if going that far back hurts performance of flat doesn't work.

Wasn't there talk of the 3000 series needing at least a 400 series chipset?

EDIT: I was thinking of this. But on re-reading it it doesn't specifically say it won't work.

Gamers Nexus has a review video for the 3600 which comes off rather well.

Would love to see a review of the 3600X or for that matter any of the similar chips with different TDPs, i know reviewers can only review what they're sampled and due to time constraints they can't cover everything but the limited sampling AMD have done has left me with some unanswered questions.

Do the higher TDP chips (3600 vs the 3600X, 3700X vs 3800X) allow higher frequencies, going on what Anandtech had to say on power consumption and overclocking it seems like it would as it increases the Package Power Tracking (PPT): The power threshold that is allowed to be delivered to the socket.

And how does RAM speed effect performance, understandably everyone seems to have tested at the default 3200Mhz but how much performance can be gained from faster speeds seeing as we know IF is tied to MEMClk, can the 3 series go higher than 3733Mhz while retaining a 1:1 IF MEMClk ratio.

We pretty much knew before the 3000 series was released that AMD would retain its lead on Intel when it comes to multi-threaded price/performance and that they'd close the gap on single/lightly threaded workloads, for me the question is how much single/lightly threaded performance have they left on the 3000 series table, could a bit more juice and faster RAM actually see them beat Intel on both fronts.

@Corky34: As of the Ryzen 3000-series, the Infinity Clock and Memory frequency are no longer tied. They can be tuned separately now.

Indeed, its what has got me thinking, despite me being an INtel purchaser for such a long time. My original plan was to turn my current board/cpu into a stream PC, but going the ryzen route would mean i don't need to do that.

Definitely things to think about. lets see how things pan out the next few months. AMD may still be getting trounced in the GPU market but i'm not above admitting I may have been wrong about Ryzen, now that the chips appear to be finally catching up wtih intel on a single thread performance.

[Tabbykatze]

Apparently, there is a suspected bug with the BIOSes, Chipsets and Ryzen processors affecting maximum clocks:

OC3D are looking into it, but not seen much mention from other reviewers yet.

@Tarinder, have you seen this or have experience something akin?

Hence saying "while retaining a 1:1 IF MEMClk ratio".

I'm glad my gigabyte B350 is supporting the Ryzen 3000 series, so at least I'll have some sort upgrade path(a cheap 3700X maybe in 2020/21) if they don't support the Ryzen 4000 series next year. A cheerful upgrade from a 2400G that would be.
