Reviews of the 3900x on a X370 Motherboard

It'southward the review nosotros've all been waiting for. Since December last twelvemonth – and particularly since CES – AMD has been teasing us nearly the new Zen 2 microarchitecture and AMD's newest Ryzen 3000 series of CPUs. Incorporating a significantly upgraded CPU architecture and congenital using TSMC'south latest generation manufacturing process, AMD has continued to run at full speed at a fourth dimension when rival Intel has struggled to move at all. The end result is that while the offset and 2d generation of Ryzen CPUs were all about AMD returning to competition and eating into Intel's substantial performance lead, the Ryzen 3000 serial is aught less than AMD'due south kickoff shot in well-nigh 13 years at meeting (or beating) Intel at their own game in the desktop CPU market. It's a big moment for AMD, and an exciting one in the CPU industry as a whole.

The new Ryzen 3000 chips marking the start "big" leap for AMD since they introduced their first Ryzen processors a flake over two years ago. Unlike concluding yr's Ryzen 2000 series, which was a more small-scale refresh and brought some tweaks to the microarchitecture and process node, this yr's Ryzen 3000 is a major upgrade for both CPU architecture likewise equally on the manufacturing node. Information technology marks AMD'due south switch from GlobalFoundries' 12nm process to TSMC's newest 7nm node. Simply what'due south more exciting is how AMD was able to really implement this switch: Ryzen 3000 isn't merely a unmarried chip, but a collection of non-compatible chiplets, introducing this blueprint paradigm in a consumer product for the first fourth dimension.

Today AMD launches its entire new CPU lineup and platform, alongside the new Navi-based Radeon RX 5700 series. In terms of CPU coverage, nosotros'll be taking a closer look at the new flagship, the $499 12-core Ryzen 3900X, as well every bit the $329 8-core Ryzen 7 3700X and its peculiar depression TDP of 65W.

Updates

• (7/eight): We've noticed large frequency boost behaviour changes with new motherboard firmware that was released on launch day (7/7). We are currently re-running all our test suite numbers and updating the article with the new data soon as applicative. For further details please read hither.
  
• (7/9): Nosotros've updated the article benchmark numbers on the 3900X. Nosotros've seen 3-9% improvements in sectional ST workloads. MT workloads have remained unchanged, Gaming had both benefits and negatives. Nosotros go on to work on getting updated 3700X numbers. Original BIOS results are marked with ** in the graphs.
  
• (vii/10):We've updated 3700X results as well. Ultimately our conclusions haven't inverse, simply AMD does narrow the gap a bit more. For a full summary of our findings, please check out this article.

AMD is launching 5 unlike SKUs today, with the 16-core Ryzen 9 3950X fix to follow onetime in September. For today's launch AMD sampled the R9 3900X and R7 3700X, and nosotros took them for a ride in the express time we had with them, covering as much as we could.

Starting at the elevation we take the Ryzen 3900X, which is a 12-core pattern. In fact it's the starting time 12-core processor in a standard desktop socket, and it rather unique within AMD'southward product stack because it is currently the only SKU which takes full advantage of AMD's newest chiplet architecture. Whereas all the other Ryzen parts are comprised of two chiplets – the base of operations I/O die and a unmarried CPU chiplet – 3900X comes with two such CPU chiplets, granting it (some of) the extra cores and the 64MB of L3 cache that entails.

Interestingly, while AMD has increased the core-count by 50% over its previous flagship processor, it has managed to keep the TDP to the aforementioned 105W as on the Ryzen 2700X. On tiptop of this, the chip clocks in 300MHz faster than the predecessor in terms of heave clock, now reaching 4.6GHz; even the base clock has been increased past 100MHz, coming in at 3.8GHz. The big question so, is whether the new 7nm procedure node and Zen 2 are really this efficient, or should we be expecting more elevated power numbers?

Meanwhile our second chip of the day is the new Ryzen 3700X, which is configured and positioned as a especially efficient model. With a boost clock of four.4GHz and a base clock of 3.6GHz, the office should even so be notably faster than the Ryzen 2700X, yet AMD has managed to make this a 65W TDP part which is going to make for some interesting analysis.

Continued Execution

Today'due south Zen ii and Ryzen 3000 launch is some other step forrard on AMD's roadmap. The company has been working on a very ambitious development roadmap for their CPU designs, and Zen two is the company'south first risk to flex their muscles and exercise a full iteration on their CPU core design.

Executing on this roadmap has been important for AMD both because it's helped them close the operation gap with Intel, and considering it'south helped to bear witness to customers (particularly hyperscalers and enterprises) that Zen wasn't a fluke, and that the visitor can reliably continue to improve its technology. This is peculiarly noteworthy because while rival Intel hasn't been standing nonetheless, all of Intel'south desktop technology for the concluding 3 years has been based on the same Skylake core architecture and variations on Intel'southward exceptional-for-the-time 14nm process. This volition eventually change, as Intel gets their desktop house in order for 2020, simply right now AMD is moving forward when Intel tin can non, allowing AMD to take full advantage of Intel's run of bad luck and wooing customers in the process.

And of class, AMD isn't done hither. For the company's engineers, today's chips are final twelvemonth's work, and the company is working on the next generation Zen 3 core. Zen three is even so a full generation away – and today is all nigh Zen ii – but AMD is making information technology clear that Zen 2 isn't the end of the road either, and that they are working to further improve their CPU microarchitecture and overall platform.

Big Operation Boosts, Particularly for Gaming

The 3^rd gen Ryzen processors promise to bring some notably large operation improvements for users. The Zen 2 core microarchitecture is said to bring over x% IPC improvements; this together with the higher clockspeeds should brand for some solid generational improvements in a lot of workloads. For gaming in particular, AMD claims that nosotros should exist seeing some big improvements – the doubled size of the L3 enshroud is said to have fabricated a notable mark on a lot of gaming titles, with AMD challenge ~twenty% to even ~thirty% improvements in some titles when compared to the last generation Ryzen 2700X.

The Ryzen 3000 Competition: Intel's Java Lake Refresh

Positioning the Ryzen 3000 series against Intel's line-upward is a matter of both operation as well as price. AMD had already made comparisons between the new SKUs and Intel's counterparts back at Computex, where we saw comparisons between similarly priced units. Co-ordinate to the company, even Intel'south pricey Skylake loftier-end desktop (HEDT) processor, the Core i9-9920X, isn't entirely out of the line of fire of the Ryzen 3900X.

Equally a quick recap to where things stand, compared to its immediate predecessor, Intel'south Coffee Lake Refresh received quite a bump in terms of both clock frequencies as well core counts. This immune Intel to erase any Ryzen 2000 serial lead in multi-threaded functioning, all the while yet maintaining a comfortable lead in single-threaded functioning.

Against the Ryzen 3000 series, the Intel line-upward will seemingly no longer accept an IPC lead. AMD hasn't been in such a situation since the Athlon 64 days well over 15 years ago, which is a remarkable turn of events. Only with that said, make no mistake: IPC is just i one-half of the equation for single-threaded performance, and the other is raw frequency, and the Intel line-upwards notwithstanding has a notable reward thanks to its meridian frequencies of up to 5GHz. And so taking over Intel's single-threaded functioning lead (at least on a consistent footing) is a tall order for the Ryzen 3000 series.

Comparison: Ryzen nine 3900X vs Core i9-9900K
AMD Ryzen 9 3900X	Features	Intel Core i9-9900K
12 / 24	Cores/Threads	8 / 16
3.8 / 4.six GHz	Base/Turbo	3.6 / five.0 GHz
sixteen (Complimentary) + 4 (NVMe)	PCIe 4.0 Lanes	16 (Costless) Gen three.0 (No Gen 4.0)
512 KB/core	L2 Enshroud	256 KB/core
4x sixteen MB 64 MB total	L3 Enshroud	16 MB
105 W	TDP	95 W
$499 (cooler included)	Price (List)	$484 (no cooler)

Taking a await at scrap pricing and positioning so, the big flagship fight among desktop processors is going to be betwixt the Ryzen 3900X at $499, and the i9-9900K at $484. Both of which happen to be the highest-end SKUs of their respective mainstream desktop computing platforms. It'due south to remembered that the AMD CPUs come with a good cooler included, while Intel's options don't include one, significant i would accept to spend extra in order to get the Intel system running.

Here AMD should have a pregnant lead in terms of the multi-threaded operation of the new Ryzen 9 series as it'south able to use 50% more cores than Intel, all while promising to remain in a similar TDP range of 105W vs 95W. We still expect the 9900K to win some workloads which are more lightly threaded merely due to Intel'due south clock frequency lead, notwithstanding this is something we'll investigate more in detail in the coming benchmark analysis.

Comparing: Ryzen 7 3700X vs Core i7-9700K
AMD Ryzen 7 3700X	Features	Intel Core i7-9700K
8 / 16	Cores/Threads	8 / 8
3.half-dozen / 4.4 GHz	Base of operations/Turbo	iii.six / iv.ix GHz
16 (Free) + iv (NVMe)	PCIe 4.0 Lanes	16 (Free) Gen 3.0 (No Gen 4.0)
512 KB/core	L2 Enshroud	256 KB/core
2x sixteen MB 32MB total	L3 Cache	12 MB
65 West	TDP	95 W
$329 (libation included)	Price (Listing)	$385 ​(no cooler)

The Ryzen vii 3700X is an interesting SKU. With only one populated CPU chiplet, the unit of measurement has one-half the available L3 cache versus the Ryzen nine 3900X. But it too has all the CPU cores within its 1 chiplet agile. In theory this does hateful that the CPU cores take less overall L3 enshroud available to them, equally they have to share it with an additional core within their respective CCXs.

With a 3.6GHz/4.4Ghz base/boost clock configuration, we expect the 3700X to outperform the previous generation 2700X in all scenarios. The competition hither based on pricing is the Core i7-9700K. Intel once again should have a single-threaded functioning reward thanks to its 500 MHz college clocks – but we'll have to see how both chips match up in daily workloads.
