AMD Ryzen 9 3900X review


Our Verdict

The AMD Ryzen 9 3900X is the handiest mainstream processor within the marketplace real now. With multi-threaded performance that destroys every little thing in its course and the inclusion of PCIe 4.0, you would possibly per chance seemingly well per chance seemingly’t rating a better processor with out stepping as a lot as the HEDT market.

For

  • Improbable performance
  • PCIe 4.0
  • Beats Intel at identical impress

In opposition to

  • Integrated heatsink is seemingly now not sufficient
  • Single core performance restful gradual

In our tips, thehandiest processorsare those who bring killer performance at a impress point that is sensible. The Ryzen 9 3900X fully nails this opinion.

This processor packs 12-cores and 24-threads in a mainstream kit for the principle time, and does it at around the equivalent impress point as theIntel Core i9-9900Okay, a processor with correct 8-cores and 16-threads.

The AMD Ryzen 9 3900X marks yet one other blow from Team Red, ramping up the intensity of the AMD vs Intel processor battle. Peaceable, though, core counts aren’t every little thing with regards to a mainstream processor, as single-core performance wants to be on point, especially at the same time as you happen to mean to expend it to play thehandiest PC video games

So, the sizable ask right here is going to be “does the AMD Ryzen 9 3900X dethrone the Intel Core i9-9900Okay as the handiest mainstream processor?” The resolution is within the raze “it relies,” as it doesn’t attain the equivalent single-core performance as Intel, but as more video games adopt multi-threaded workloads, the answer to that ask will get moderately more complicated.

Mark and availability

Talking of which, at the same time as you happen to ought to must salvage a excessive-stop desktop (HEDT) 12-core processor that can seemingly well abet up with the AMD Ryzen 9 3900X, you’re going to must exhaust seriously extra cash and salvage something fancy the $1,189 (£1,329, AU$1,799) Intel Core i9-9920X. Even at the same time as you happen to realize lumber with thisIntel Basin Falls Refreshchip, you gained’t basically salvage the equivalent stage of performance.

The AMD Ryzen 9 3900X is available now for $499 (about £390, AU$720). Here’s for sure a enormous impress point, as it goes real up in opposition to the $488 (£498, AU$777) Intel Core i9-9900Okay while offering an additional four cores. It doesn’t enhance as excessive, and the retail field isn’t as frigid, but any creatives that are taking a stumble on for a enormous processor with out leaping for aThreadripper 2nd Generationchip ought to make your mind up on out leer.

Parts and chipset

AMD Ryzen third Generation, and theZen 2architecture itself, is considerable because it brings 7nm processors to the mainstream for the principle time. But, there’s a lot more happening below the ground than a smaller manufacturing node. 

The greatest enchancment, and the finest to digest, is the massive enhance to IPC, or instructions per clock. AMD claims that it was as soon as in a position to magnify IPCs in its third generation Ryzen chips by as a lot as 15%, which works a protracted technique to explaining why single-core performance sees this form of enhance over something fancy theAMD Ryzen 7 2700X

That increased IPC improvements, alongside with the massive turbo enhance of 4.6GHz mean that even in single core performance – long a feeble point of AMD’s processors – comes within reaching distance of Team Blue’s chips. 

One thing that the switch to 7nm silicon has allowed for on the assorted hand, is an magnify in cache dimension. AMD is now labeling its L3 and L2 cache in a combined spec of ‘GameCache’ – though functionally it’s the equivalent thing. But, since the 7nm CPU cores are contained within their non-public chiplets, AMD was as soon as in a position to pack far more in – with a whopping 64MB of L3 and 6MB of L2, for a combined 70MB of GameCache. Here’s a sizable deal, as it permits for far faster performance, especially at the same time as you happen to’re taking pictures for excessive framerates in 1080p video games, and is seemingly to be especially efficient in primitive esports titles fancy Counter Strike: Global Offensive. 

One other enchancment that AMD Ryzen, and more namely the X570 chipset, brings to the table is the long-awaited inclusion of PCIe Gen 4. Now, the handiest graphics cards that expend PCIe 4.0 this day are the AMD Radeon RX 5700 XT and AMD Radeon RX 5700, but your GPU is practically much less worthy than the improvements it would bring to thehandiest SSDs

We got a Aorus PCIe 4.0 SSD to test, and the speeds we scrutinize are tips-blowing. We were in a position to salvage sequential reads of 4,996 MB/s, a 29% enhance over our earlier fastest SSD, the Samsung 970 Pro. Out of the final aspects that Ryzen third Generation brings to the table with the recent X570 chipset, this would seemingly well be certainly one of basically the most impactful – and as well explains why there are so worthy of excessive-stop AMD motherboards this time around. 

Lastly, the shrink down to 7nm permits for far better energy efficiency. Thanks to the Zen 2 architecture, AMD Ryzen third Generation processors fancy the Ryzen 9 3900X wants to be as a lot as 58% more efficient than linked Intel processors. This isn’t basically the most attention grabbing characteristic right here, but, hiya, it’ll translate to lower electricity bills, and in this day’s financial system every minute bit helps, real?

Efficiency

It shouldn’t be too terribly pleasing that a 12-core, 24-thread processor with a 4.6GHz enhance clock is an absolute beast with regards to performance. The AMD Ryzen 9 3900X is straight up the fastest piece of silicon you would possibly per chance seemingly well per chance seemingly rating with out wading into the HEDT scene – in spite of every little thing till the Ryzen 9 3950X comes out in September 2019. 

The AMD Ryzen 9 3900X especially shines with regards to multi-threaded workloads. As an instance, in every Geekbench and Cinebench R15, the 12-core processor scored a whopping 44,160 and 3,097, respectively. Compared to the Intel Core i9-9900Okay, which ratings 33,173 and 1,873 within the equivalent assessments, it’s an night and day distinction. For approximately the equivalent impress point, the Ryzen 9 3900X is between 25%-40% faster than the Intel Core i9-9900Okay in multi-threaded loads.

Unfortunately, this doesn’t moderately translate to single-core performance, although AMD is closer than it’s ever been to matching Intel core for core. In our single-core GeekBench and Cinebench assessments, the Ryzen 9 3900X scored a 5,569 and 203, respectively. Here’s positively a super enchancment over the Ryzen 7 2700X, but it’s slower than the 9900Okay, which scored a 6,333 and 211 within the equivalent assessments. But, that’s restful between a 4% and 13%, so the multi-core gains in general outweigh them. 

And, with regards to gaming, the favorite rule of thumb for about so long as lets assign in tips is that single-core performance is king. On the opposite hand, in a lot of smartly-liked video games – seemingly attributable to the prominence AMD Ryzen processors fill gained – multi-core performance is changing into an increasing number of vital. As an instance, in Whole Battle: Warhammer II, we were seeing increased body charges at 1080p with the 3900X than with the Intel Core i9-9900Okay with the equivalent Nvidia GeForce GTX 1080 Ti GPU – as a lot as 17%, for sure. 

The sizable arrangement back right here, though, is energy consumption and thermal performance. Now, we wants to be abundantly obvious right here: we tested utilizing the incorporated Wraith Spire cooler, in topic of utilizing an AIO liquid cooling resolution. Peaceable, we saw temperatures prime at 83 levels Celsius, and energy consumption lumber the final arrangement as a lot as 145W. So, while the incorporated thermal resolution will attain in a pinch, we recommend picking up an aftermarket cooler – something possible customers for a chip of this caliber will potentially attain anyways.

Ideal verdict

The AMD Ryzen 9 3900X is an absolute beast of a processor, which it fully wants to be with its core count and excessive impress impress. In case you’re taking a stumble on for absolutely the handiest processor money can rating on a mainstream processor, stumble on no further. Whether you’re playing PC video games or even doing hardcore video and 3D work, the AMD Ryzen 9 3900X is an absolute unit of a chip.

On the opposite hand, you wants to assign in tips that there are some workloads the save the Intel Core i9-9900Okay will restful excel in. Mature video games that are utterly single threaded, fancy World of Warcraft, will restful attain better on an Intel processor – but that gap is with out problems initiating to slim.

The inclusion of PCIe Gen 4.0 is also a super earnings to deciding on the Ryzen 9 3900X, as it’ll make contributions to a faster gadget general, thanks to speedier SSDs – and that’s something you would possibly per chance seemingly well per chance seemingly handiest salvage with Ryzen 3000 and X570. Over the wonderful couple years, AMD has been reaching for dominance within the desktop CPU world, and with the Ryzen 9 3900X, it is lastly there.
