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

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

Some people still see AMD as “the cheap option.” Historically, that point of view wasn’t entirely unjustified. AMD’s first microprocessors were reverse-engineered Intel designs, and budget chips like the K6-2 have been some of its biggest successes, financially. However, the team-formerly-colored-green was also responsible for the first 1-GHz x86 CPUs, the creation of the x86-64 ISA, and the first monolithic multi-core desktop CPUs.

Zen 2 is the latest example of AMD’s ability to take risks and blaze new trails in microprocessor design. Even though these CPUs are built in an entirely new way, they’re pin-compatible with extant boards. They see generous per-clock and per-thread performance gains over the previous generation, yet still increase clock speed, too. The fact of the matter is that the Ryzen 7 3700X and Ryzen 9 3900X are extremely fast CPUs. Even if you skipped to the end and didn’t read the rest of the review, you still don’t have to take my word for it; check out these scatter plots.

This first scatter chart collates all of our non-gaming tests into a single score and then compares them with the Ryzen 7 1800X’s performance as a baseline. Ever since the launch of the very first Ryzen CPUs, we’ve been saying that Ryzen is a no-brainer for creative and scientific computing—as long as your workload isn’t a specific weak point for AMD’s architecture.

The thing is, this third generation of Ryzen CPUs has a lot fewer weak points. The improvements that AMD made to its Zen core in Zen 2 have largely closed the gap with Intel’s CPUs, at least for desktop and productivity purposes. Most of the tests where Intel used to dominate, like our Javascript benchmarks, our Qtbench code compilation test, and Handbrake video encoding, now show performance parity if not an AMD win. Even in tests where the third-generation Ryzens are behind, it usually isn’t by much.

All you really have to do is look at that bright blue dot for the Core i9-9900K and then look at where the Ryzen 7 3700X sits in relation. After, look at the Ryzen 9 3900X. In comparison, AMD’s CPUs give you the option to pay a lot less for a bit lower performance, or to pay the same price for a much more capable CPU in most types of work. What about for play?

It would be easy to look at the above charts and conclude that these new Ryzen CPUs aren’t great choices for a gaming rig. Sure, it’s undeniable that both third-generation Ryzens trail their nearest-priced competition in 1920×1080 gaming. With that said, I invite you to go back a half-dozen pages and take a look at our gaming data. Even the slower of the two chips drives our Aorus card to 99th-percentile frame times that guarantee over 70 FPS in titles that hit the CPU extra-hard. Moreover, they do it without presenting inconsistent, spikey frame-time plots.

Make no mistake: if you’re a hard-core CS:GO competitor or a 240-Hz DyAc addict, you’ll want an Intel CPU. Everyone else, especially those playing with more modest GPUs or in high resolutions, should be be perfectly satisfied with the gaming performance of these third-generation Ryzen chips—and I say that without even taking into account the fact that some games, like Crysis 3 and GTA V, love these processors.

Of the two, the eight-core Ryzen 7 3700X makes a better case for itself as a gaming CPU. It comes awfully close to the Core i7-8700K in overall gaming performance, and tops it in two titles. It’s also capable of streaming using x264’s medium preset, where the Core i7 just can’t hack it. Meanwhile, the Ryzen 9 3900X offers slightly better gaming chops and stunning performance-per-dollar in productivity apps. Anyone who plays games and produces content on the same computer will be well-served by a Ryzen 9 CPU.

Having said all that, there’s also the matter that these are the most efficient CPUs we’ve ever had on the bench. Plus, the X570 platform offers more and faster high-speed I/O than anything Intel offers on the desktop right now. Finally, like every Ryzen CPU, these chips are fully unlocked for overclocking. I didn’t have time to explore that avenue in this review, but given how efficient these processors are, a modest clock speed bump could be virtually guaranteed to those who go looking for it.

It’s worth remembering that we got the performance we did from these chips with their included Wraith Prism coolers, too. Builders don’t have to shell out extra for a heatsink that can hold the Ryzen 7 3700X or Ryzen 9 3900X in check, but if they do, AMD’s SenseMI intelligence will simply take that thermal capacity into account and let the chips run harder within certain boundaries. The fact that AMD includes fine stock cooling in the box only puts an exclamation point on the value of these processors.

Any time a company talks up its products, you have to take it with a measure of salt. AMD in particular has a history of making bombastic claims of dubious merit, but this time around, that’s not the case. The leaps that these processors make from their second-generation forebears are the sort of generational improvements that make me wistfully recall the era of the Athlon thumping the Pentium 4. We’re not to that point again—yet—but these are the first Ryzen CPUs that I can recommend unreservedly, and that’s definitely worthy of a TR Editor’s Choice award.

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 »

“aside from 1-2 nanoseconds of wire latency”

Hmm. Signals travel through bond wires at no less than ten inches per nanosecond.

Those are some long bond wires. My guess is they’re including every possible gate delay and adding a few clock cycles into this “1-2 nanoseconds” quote.

I was thinking about upgrading to the 3700x until I saw some benchmarks that had the i5-9600K in it. IMO the i5-9600K would be a better / slightly cheaper purchase.

i agree and in some areas (australia at least) the 9600k has had a price dump to in between the 3600 and 3600x but it seems usa doesnt have the price drop for them yet (at least newegg that i checked)
a z170 motherboard is close to the price of a decent b450 motherboard too

[quote=”Steven Walton”] Ryzen 5 3600 offers a tremendous value. It smoked the Core i5-9600K in every single application benchmark we ran and worst case matches its single core performance. You get 12 threads opposed to just 6, so it’s no doubt going to age better, but this time you don’t have to roll the dice on Ryzen’s longevity, as it’s already faster today. [/quote]

Does anyone have a clue about what is going on with the AIDA Memory bandwidth results?
I noticed the same performance on other review sites.
The Ryzen 3 3700X has a very low write bandwidth, and also its read bandwidth is lower than all the other cpus.
On the other hand, the Ryzen 9 3900x performs great. The latency is about the same between the two.

Memory write bandwidth is halved on the single chiplet parts. This was an intentional move on AMD’s part.

Zach, A nicely done review! The 3900X is really an upgrade. I like you putting all the traces in a grid. Its easier to compare them; good idea. Can one say that one advantage of the chiplet architecture is that the fastest chiplets can be reserved for the high end CPU? It seems it must be that way when a CPU with more cores can clock higher than one with less cores. It lets AMD turn the paradigm on its head. Faster CPU’s are assembled with the faster chicklets. Period.

A Tesla power wall can output 5kw and costs about $7k.

40,000 powerwalls would output 200 MW.

Let’s assume Tesla gives discounts on bulk purchases, so maybe $5k per powerwall , so $200 million.

Compared to the cost of this complex of fabs, that sounds like a reasonable price to me

I regularly visit an offsite datacenter in London where we keep some DR servers and that place is vast, yet an insignificant spec compared to the size of Toshiba’s NAND facility.

The ISP datacenter is home to Microsoft, Cloudflare and one other large anonymous customer who dwarfs the other two in floors occupied (so basically either Amazon or Google). Three Caterpillar gas generators provide up to 18MW of on-site power and the building behind them is, I’m told, filled with nothing but batteries and cooling for those batteries.

Unfortunately, TR doesn’t exist in one big office. The Focusrite audio interface we have used in previous reviews was purchased out-of-pocket by Jeff Kampman, our previous editor in chief, and I don’t have access to any such device.

There’s also the matter of the complicated licensing for the expensive software required to run DAW testing. In the end, no matter how much I wanted to do it — and I did — there was simply no way.

Where’d all the comments go with the new website design?

Anyway (if this is the right place) [url=https://www.youtube.com/watch?v=qk3PD-4zPN0]Here’s Der8auer’s video on X570 chipset power consumption[/url] (skip to 14:00 for full results table).

Looks like AMD REALLY borked their attempt at an in-house chipset design. Power consumption is 2x what the X470 chipset needed. PCIe4.0 imparts nearly zero extra power consumption from the chipset. And he was able to keep the chipset at 73C under a comically tiny passive heatsink.

Spunjji
Guest
Spunjji

Agreed thoroughly on that point. In fact, it’s that specific factor – what does this add *now* for my extra money – that causes me to cast shade on the 2000 series as a whole.

The 9700 Pro and 8800GTX were both absolute beasts when they were released, and just got better as they matured. I’m not convinced that we’ll see the 2000 series in a similar light two to three years from now.

I think that video skips a few important parts. Firstly, the older chipsets didn’t even have PCIe 3, which is a very important distinction. PCIe used a different encoding scheme than the older versions and has quite different transceiver requirements. To support PCIe 3 (or 4) the chipset also needs to support PCIe 2 and 1, meaning it needs all the hardware for both transceiver standards. As you know form all the benchmarks, tests, overclockin etc, Power consumption has a linear relation to switching frequency. as PCIe 4 switches literally twice as fast as PCIe 3 the dynamic power consumption… Read more »

You note a regression in the memory latency test. However, I note that the Ryzen 3000 CPUs are being tested with 16-16-16 timings vs. the 14-14-14 timings of the others. This is likely because the Ryzen 3000 is at 3600 while the others are at 3200. Can you tell us what the AIDA 64 memory latency is when the memory is at 3200 14-14-14 speeds? I think that memory latency tests are usually used to show theoretical architectural differences, so the other variables in memory speed should be held constant.

This is of course not the first time it’s being done, but I’m not fond of the concept of “chiplets” for CPU tasks. Is AMD in trouble here? I thought they were starting to kick some ass with their recent offerings, but now I’m not so sure. Are they having trouble making the new fab process work for full-blown CPUs? Or have they hit a limit (cost, reliability, whatever) designing CPU stuff to all fit inside a single CPU chip? Or a combined CPU+GPU chip?

just brew it!
Guest
just brew it!

I am guessing it was a combination of yield concerns on the new process, and wanting extra flexibility to mix-n-match compute dies in different combinations to meet different needs. They’d already started down this path with Threadripper and Epyc; splitting out the I/O was kind of a logical next step I guess.

The smaller process node is also less of an advantage for I/O; you don’t have transistor-dense structures like cache and vector ALUs/FPUs, and you need larger transistors to drive the external buses anyway. So you might as well use a more mature process for that.

Multi chip modules (MCMs) have become a lot more popular in the semiconductor world outside of the CPU business. There are a lot of advantages of MCMs and AMD probably just realized that the performance advantage of using a single die wasn’t worth giving up all the advantages of an MCM.

I wouldn’t be surprised if we see Intel do the same thing in the near future.

Costs per wafer increased pretty dramatically with the move the 7 nm and, being a new manufacturing process, yields are going to be lower. The chiplet strategy allows AMD to produce smaller dies that increase effective yields for the same defect density, allows them to bin more aggressively because of the larger number of dies, and allows them to reuse the 7 nm parts across multiple product lines. It’s certainly an economical decision first and foremost, but it’s not without its benefits.

Rage Wars was so much fun, but broken. We loved it so much in spite of not being able to progress past a certain point.

The fastest chiplets can be selected to make a very fast multi-core while leaving the slower chiplets for less expensive models. Otherwise the base and max clock could not be going up as core count goes up. This is a great new paradigm!

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 »

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

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.

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.

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.

Interested to know why the 3700X is just 65W, but the 3800X needs 40W more (+60%) for only an extra 300MHz (+8%)

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.

[quote<]Plus, every X570 board has active cooling for the chipset[/quote<]Not quite - the Gigabyte X570 Aorus Xtreme has passive chipset cooling, but AFAIK it's the only one so far. Wish there were an 'X560' or such bringing some of the IO benefits and futureproofness without the much higher chipset power consumption. I have bad memories of a tiny loud chipset fan from the early P4 era and it's not something I aspire to revisit.

Under your Test Methods lists, can I suggest providing the specific build of Windows used? Win10 1903 has thread placement optimizations for these non-monolithic CPU designs. Would be curious to see a couple of select benchmarks comparing 1903 to 1809 too if there’s time.

Did AMD just take the IPC crown? 😮 😮 😮

[url<comment image[/url<] 10th gen Sunny Cove is thought to gain 18% in IPC, but until then, looks like AMD did the unthinkable.

Thanks for an extremely timely review. Would be curious to find out whether performance chances noticeably with good cooling (for example Corsair H115i or similar).

Given that I can simply replace my 1700X with a 3900X on my X370 motherboard from two years ago, this seems like a very nice upgrade.
