AMD’s Ryzen 7 3700X and Ryzen 9 3900X CPUs reviewed

AMD’s X570 chipset

As has been tradition so far, AMD has a new motherboard chipset coming along with its new CPUs. However, this one isn’t a revision of the “Promontory” design used in the X370 and X470 chipsets. Instead, the new chipset is designed by AMD in-house. More specifically, AMD says the new chipset is “directly derived” from the IOD chiplet used inside the processor packages. They’re not one and the same, though; the X570 chipset is manufactured on GlobalFoundries’ 14-nm process node.


A diagram displaying all of the I/O available from a 3rd-gen Ryzen CPU and X570 chipset.

Naming the new chipset “X570” is almost doing it a disservice, because it’s much more than the simple generational upgrade that the name implies. The X470 chipset offered two USB 3.1 Gen 2 ports, six USB 3.0 ports, six USB 2.0 ports, four 6 Gbps SATA ports, and eight lanes of PCIe 2.0.

Meanwhile, X570 contributes eight USB 3.1 Gen 2 ports, four USB 2.0 ports, as many as twelve 6Gbps SATA plugs, and 16 additional general-purpose PCIe 4.0 lanes on top of the 20 usable lanes from the third-generation Ryzen CPU. Altogether that means one of these systems can have 36 usable PCIe 4.0 lanes, 14 SATA-III ports, and twelve USB 3.1 Gen 2 ports.

All that connectivity doesn’t come for free: the X570 chipset is relatively power-thirsty. We don’t have exact figures on the matter, but with the twelve-core Ryzen 9 3900X installed in our ASRock X570 Taichi, the idle power draw is about the same as for our Threadripper 2920X installed in the X399 Aorus Extreme. Plus, every X570 board has active cooling for the chipset—a quality we’re not exactly wild about.

These CPUs will work in certain older Socket AM4 motherboards, and AMD offers the above chart as a “general guideline” for compatibility. Motherboard vendors are free to extend support to whatever they feel like, though. If you’re interested in upgrading an existing Ryzen system to the new hotness, better check with your motherboard vendor first.

A pair of platters

Along with the chips, AMD sent us a pair of motherboards on which to socket said CPUs. While neither model is a dizzyingly-expensive top-end mainboard, both are quite fancy.


ASRock X570 Taichi

The motherboard we used for most of our testing is the ASRock X570 Taichi. Taichi is a well-established sub-brand for ASRock that marks full-featured, high-quality motherboards, although they’re rarely the fanciest board within a given series. This motherboard includes a trio of PCIe 4.0 x16 slots, triple PCIe 4.0 x4 M.2 sockets, and three USB 3.1 Gen 2 connections—two of which are Type-C ports. Wi-Fi 802.11ax and Bluetooth 5.0 come as standard, as does Intel-powered 1-Gbps Ethernet.


Gigabyte X570 Aorus Master

Gigabyte’s X570 Aorus Master is just one step below the company’s top-end overclocker-focused X570 mainboard. As a result, it’s absolutely jam-packed with features, like 2.5-Gbps Ethernet, gloriously overbuilt onboard audio with an ESS Sabre 9118 DAC and isolated WIMA capacitors, and a direct 12+2-phase digital VRM that incorporates IR3550 PowIRStages. There’s no particular reason that we used the ASRock board for testing; it was simply the box I opened first.

Our testing methods

As always, we did our best to deliver clean benchmarking numbers. We ran each benchmark at least three times, and took the median of those results. Our test systems were configured as follows:

Our test systems shared the following components:

Graphics card Aorus GeForce GTX 1080 Ti Xtreme Edition 11G
Graphics driver GeForce 430.86
Power supply Seasonic Prime Platinum 1000 W

Some other notes on our testing methods:

  • All test systems were updated with the latest firmware, graphics drivers, and Windows updates before we began collecting data, including patches for the Spectre and Meltdown vulnerabilities where applicable. As a result, test data from this review should not be compared with results collected in past TR reviews. Similarly, all applications used in the course of data collection were the most current versions available as of press time and cannot be used to cross-compare with older data.
  • Our test systems were all configured using the Windows Balanced power plan, except for AMD systems that used the Ryzen Balanced plan.
  • Unless otherwise noted, all productivity tests were conducted with a display resolution of 2560×1440 at 60 Hz. Gaming tests were conducted at 1920×1080 and 144 Hz.

Our testing methods are generally publicly available and reproducible. If you have any questions regarding our testing methods, feel free to leave a comment on this article or join us in the forums to discuss them.

Before we move on, I want to quickly say thanks to AMD, Gigabyte, G.Skill, and ASRock for providing the review hardware. That includes the CPUs and motherboards, as well as a memory kit and SSD:

G.Skill Trident Z Royal 2x 8GB DDR4-3600 DDR4 SDRAM

Gigabyte Aorus NVMe Gen4 SSD, 2.0TB

If they do that, then they should technically add the cost of the corsair into the price scatter-plot. It would only be fair since wraith coolers are free.

AnandTech had that problem back in 2001 IIRC and fixed it. There’s a Print option that makes the entire review a single page. ScanAudio speaks very highly of the new AMDs and DAWBench tests show the 3700X on par with 9700/9900 and beating all Intel’s on IPC from the 7700k back. Pretty impressive. There’s also evidence of super low latency overclocked DRAM that actually speeds up certain workloads. This definitely is no reverse engineered Design. Best news, Intel is going to counter before years end, leaks no doubt. CES 2020 will be Intel’s revenge. I’m still getting the 3700X just… Read more »

im actually selling my ryzen 1700X and getting an intel mostly just because it might be the last overclockable cpu if intel goes the same way and releases cpus so close to the limit that they cant be clocked any further
i know im a niche but i actually like overclocking and since intel cpus are pretty cheap now after the price cuts im going back to the dark side

Unless you need the horsepower of additional threads, I don’t see much reason to replace the 8700K. That’s still a very capable chip.

Unfortunately, the age of overclocking is largely over. Manufacturers are increasingly squeezing every last inch of performance out of the box, and the little left remaining is now often handled pretty well by software overclocking tools. I actually have more fun undervolting my CPUs now to maintain performance while lowering the power bill.

Zen 2 is more power efficient, roughly on par with Intel in IPC, and significantly cheaper. Those are huge wins for the marketplace, but not as sexy as big overclocker.

Solid review Zak, thanks. Great to see TR with a launch day review again. I have a few questions: 1. With the 3700X, are both CCXs on the same CCD? There was a pre-lease rumour that claimed there would be one CCX on each of 2 CCDs? 2. The 6-core 3600 seems to get the same amount of L3 cache – 32MB – as the 8-core 3700X? Is that right? 3. Why is AIDA64 memory write so low on the 3700X vs the 3900X? 4. Crypto seems comparatively weak vs. Intel – any thoughts as to why and performance ramifications… Read more »

Why?
They both R5 and i5 have 6 cores and games don’t really use more than that and from other reviews I have seen sometimes smt hinders performance and sometimes it helps so it’s a wash with smt
I have learned to never predict future game core usage and to buy what’s good NOW and to upgrade often instead of buying the expensive thing hoping it will last long by predicting future game usage
My 3930k taught me that lesson

For non gaming it’s a no brainer everyone knows ryzen is way better for the price

If I was in the market right now I wouldn’t buy an i5. I’d get an i7, or maybe the R5 3600X. The thing is that the i7 9700k is $400, and local deals are… local. If you can get one that’s great, but not everyone can.

Pretty disappointed in ryzen myself
With all the talks about high clocks it sucks seeing them pretty much at their max clocks out the box and still behind Intel in gaming overall

It wouldn’t be so bad being behind if you could overclock them but they are pretty much max clocked out of the box and even with high voltage reports are they don’t go any higher than around 4.3ghz all core

With the recent discounts on intel CPUs they are a better alternative at a better price

Why would you be sad about the 9600k?
At the same clock it’s still faster than ryzen in games (but not in cinebench which is odd) and it comes with a faster clock and overclocks better
Not sure how much it cost you but with the discounts on it at my local computer shops it’s cheaper than the 3600X

Pet peeve: people using “exponentially” for any increase more than linear, or for any accelerating growth process. A little bit of math leads us to expect that the dominant term in the relationship between power consumption and processor clock is cubic rather than exponential. And from what I’ve seen that holds reasonably well for these kind of relatively small frequency changes close to a processor’s design point. Ignoring lower order terms, that would lead us to expect the 3800X to take 27% more power. I suspect that the 40W TDP difference, which is 62% more, isn’t just the higher power… Read more »

I’ve been thinking about the AMD 3700X for my next build. One reason I hesitate is that I got badly burned by the chipset for the Athlon 64 build I did years ago.

My youngest son wants me to update now since he’ll get my old system, but I’m in no rush and I was quite surprised by how well the Core i7-8700K held up.

X370 and X470 follow-up would be superb. I have two X370 Asus boards (Strix and Prime) that I would be willing to loan to TR for a follow-up review. (And that could come with a Ryzen 5 1600 in it.)

I agree with you on the 3700X also. What a killer value.

I really would have thought my 7900x would have been more future proof. It’s delidded and running on an all core 4.6 OC, so it’s fine but 2 years ago 10 coars and 20 threads was SO INCREDIBLE, and it’s like that 1,000 CPU plus the extra 200 for delidding, and well it will be (and is fine). However when you drop that kind of coin you don’t expect it to be disrupted to quickly, I guess in another year I might be buying whatever comes after this from AMD should this process continue. Really excited to see competition back!… Read more »

I’m tempted to buy, but I do not trust the mothers with factory fans.

I absolutely need a fan replacement article for those fans on the mother. Is it doable and practical? if you need to discard a mother because the fan failed, then it is worthless.

I lost a lot of hardware to accumulation of carpets of dust.

I think it simply comes down to AMD simplifying things for OEMs. By providing two TDP targets OEMs can safely make a “65W” cooler and a “105W cooler.”

Having lived through nearly 16 years of their CPUs largely whelming though, it is worth taking a moment to appreciate this return to competition regardless. I do expect Ice Lake will take back the IPC crown in a big way in short order, but that looks like it can only clock high enough to be suitable to ultrabooks for now.

X570 chipset is quite a bit more power-thirsty than earlier Socket AM4 chipsets—so much so that AMD’s partners equipped every single X570 mainboard with active chipset cooling.

This is incorrect. The oarus xtreme x570 doesn’t have a chipset fan.

For me a graphics card is simply a waste of money, I don’t play games.

And that’s not to say I think the Performance and Perf-Per-Watt of these new Ryzen’s aren’t very impressive, because they are.

It’s just it would take Intel to make “Netburst 2” to make me switch back to AMD again, and with Sunny Cove coming, with purportedly a similar percentage IPC improvement to Zen 2, on I hope 10nm, that doesn’t seem likely, I think Intel learned their lesson.

I also hope Intel learned it with the 10nm debacle………

Anyone who thought they were going to get 5ghz were um, optimistic. It looks like most reviewers got around 4.3 on all core overclocking (from what I could tell). I say they had pretty decent results overall. Bringing the prices down on CPU’s is always nice. I’ll pass but I have a current cpu. Changing out processors and boards is just not worth it.

Well, neither version is obsolete. The 1809 build will continue getting updates for quite a while. More importantly, not everyone updates to the latest Windows release as soon as it’s released, especially since 1903 hasn’t even been fully rolled out by MS. This optimization theoretically should provide a decent benefit for processes that spawn threads that are tightly dependent on each other, for instance processes like games. Windows by far being the gaming enthusiast OS of choice and TR typically benchmarking gaming related hardware and software, I think it makes sense to benchmark something that could possibly provide a tangible… Read more »

I’d be curious to see gaming numbers for the 3600X if y’all get your hands on one. From what I’ve heard there is indeed not much use for more than 4-6 cores in current games, seems like that may be the real MVP for a dedicated gaming box.
