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

Javascript benchmarks

In 2019, Javascript comprises the majority of what most people ever do on a computer. Javascript benchmarks are typically single-threaded synthetic tests that can give you a vague idea of how a given machine will handle script-intensive webpages and web applications. Because these tests generally involve a succession of multiple short-but-intense workloads, the responsiveness gains from UEFI CPPC2 (see page 2) play a big part here.

These tests were performed in Chrome 75 on Windows 10 1903 with all updates installed and all hardware vulnerability mitigations active.

Even though Intel still holds a solid lead in Jetstream, the massive improvement from the Ryzen 7 2700X to the Ryzen 7 3700X is praiseworthy. Other tests see similar score uplifts, with AMD even claiming the Kraken benchmark. Performance gaps between the Coffee Lake and Zen 2 processors in these benchmarks seem to correlate with clock rate, which is quite a win for AMD.

WebXPRT 3

The WebXPRT 3 benchmark is meant to simulate some realistic workloads one might encounter in web browsing. It’s here primarily as a counterweight to the more synthetic microbenchmarking tools above.

Once again, the difference here seems to mostly be down to clock rates.

Webassembly

Webassembly, often abbreviated to “Wasm,” was created by an assortment of browser builders in cooperation with the World Wide Web Consortium (W3C) with the intention of producing a portable binary format and programming language for high-performance web applications. PSPDFKit’s WASM benchmark simulates real-world Wasm workloads, and is intended to give an impression of a given machine and browser’s performance in the new format.

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 »

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.

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.

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.

it made me smile every time it beat a Threadripper, let alone the 9900K @ “time beyond 16.7ms”

i don’t suppose you could test core-to-core cross-CCX latency? e.g. pcper.com/2017/06/the-intel-core-i9-7900x-10-core-skylake-x-processor-review/3/

the context i’m looking for is if it’s low enough for RPCS3 (PS3 emulator) to utilize more than 1 CCX for SPE emulation

A quick area under the curve analysis of the blender numbers (with the 8700K as the baseline) gives the following results:

CPU — Efficiency relative to 8700K
3900X — 254.0%
2920X — 176.1%
3700X — 173.2%
9900K — 141.0%
7900K — 130.8%
2700X — 108.7%
1800X — 108.4%
8700K — 100.0%

That’s an amazing increase for a single generation and fantastic performance overall. I’m interested to see what a 3800X can do with PBO.

It all looked pretty impressive to me until I go to power efficiency, but then, MIND BLOWN!
Just looking at the 3700x, it matches the 9900K pretty closely, but consumes ~ 26% less power, and that is for the whole system?
Nicely done, AMD!

Theres almost no reason to get an Intel solution right now unless you got a good bundle deal or have a use case for the iGPU. Intel only hope in the desktop market lies on the Sunny Cove family.

1. In multithreaded apps the performance Delta from the 1800X (8 core) to the 9900K (8 core) is about the same as from the 9900k to the 3900X (16 coar). Clearly it’s impossible for Intel to EVAR catch up.

2. Given how 16 miracle Coarz on 7nm are still will behind the core parts in games, we now know why AMD put on that ridiculously unrealistic “streaming” demo.

3. We’re canceling…. ALL FPGAS! See, we have surprises.

“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.

[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.

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.

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.
