Amd Ryzen 9 3900X Matisse 3

Here it is, folks: the Ryzen 9 3900X. Not quite the best of the bunch anymore – not since that Ryzen 9 3950X came along with its 16 cores – but it’s still a mighty powerful 12-core/24-thread multithreaded champion. Armed with the Zen 2 architecture, this chip has helped close the gap on hãng sản xuất intel after years of playing catch-up.

AMD finally gained the process node advantagefromIntel with its latest CPU architecture. But AMD’s inaugural client 7nm efforts are not limited lớn processors alone, asJuly 7also marked the launch of theRDNA GPU architecture with the RX 5700-series (formally known as AMD Navi). Thereleasehasseen two fresh-faced graphics cards, the RadeonRX 5700 XT & RX 5700,head tomarketto compete with Nvidia’s Super lineup.

We’ve putt the Ryzen 9 3900X, first of its name, under the microscope. This 12-core, 24-thread processor is the most capable, highest clocked cpu from the red team’s Zen architecture to date – coming in at $499 – RGB cooler included, of course.


While afundamental change in chip design, 400-series & most 300-series AM4 motherboards will tư vấn the latest 3rd gene Ryzen chips, so there’s no need for the latest X570 chipset if your rig is already red. However, that brand new chipset also unlocks complete PCIe 4.0 bandwidth, capable of driving double the bandwidth between your chip, storage, GPU, và I/O devices astoday’s standard, PCIe 3.0.

AMD Ryzen 9 3900X specs

The Zen 2 architecture is built on the 7nm process and incorporates a new mixed-node chiplet design. This hands the red team a new balance between power and performance that is incredibly scalable – & none more obvious today than with the Ryzen 9 3900X.

The Ryzen 9 3900X is the highest clocked 3rd gene Ryzen chip available right now, booting from 3.8GHz up to 4.6GHz. It will soon be superseded by the Ryzen 9 3950X come September, at which point the adroit 16-core Ryzen 9 3950X will take the crown. But, for now, itrules the roost, bringinga whole lot of performance for gaming & heavy-duty multitasking to the fore.

That’s largely thanks to the Zen 2 architecture acting as the backbone for the performance improvements of AMD’s Ryzen 3000 processors. AMD has a knack for thinking outside the box lớn compete with its strong rivals, this time producing a design that puts its Infinity Fabric lớn good use between a single 14nm I/O die (cIOD) & either one or two 7nm chiplets (CCD). The Ryzen 9 3900X is the only chip so far to lớn utilise two 8-core CCDs, each CCX within slightly hamstrung to lớn hit that 12-core/24-thread overall count.

Diving into thearchitecture, AMD has increased Instruction per clock (IPC) by a whopping 15% with Zen 2. This has been achieved through various upgrades và streamlining efforts applied across branch prediction, cache, integer execution, and floating point. The updated core complex has been designed in a similar fashion to its predecessor, with large banks of L3 cache sandwiched between L2 cache và a discrete bộ vi xử lý core on either end.

Each of the four CCXs within the Ryzen 9 3900X, while limited to ba phần tư cores a piece, retains access to all 16MB total L3 cache available per CCX.Hence the 12-core Ryzen 9 3900X featuresidentical L3 cache accesstothe mammoth 16-core Ryzen 9 3950X at 64MB.

When we move away from the CCX complex and out lớn the memory controller located on the cIOD, there’s been some serious upgrades here, too. Memory compatibility was something of a bugbear with previous Ryzen generations, especially the inaugural kit, but there have been efforts to rectify that with the third gen units.

The interconnecting Infinity Fabric (Fclk) has been decoupled from the memory controller (Uclk) between the cIOD và CCD, allowing for much greater memory capabilities with 3rd gen Ryzen. DDR4 over 4,200MHz is rated “with ease”, while even 5,133MHz kits are on the table. However, the sweet spot lies around 3,600/3,733MHz. Beyond that tốc độ Uclk switches from a 1:1 Uclk/Flck ratio to lớn 2:1, a byproduct of which is an increase in overall latency.


For the Ryzen 9 3900X testing below we’ve opted for a straight 3,200MHz across the board. As such there’s a little performance left on the table for 3rd gen Ryzen – & Intel’s chips too for that matter – but overall we can gleam a strong comparison of the Zen+, Coffee Lake, & Zen 2 architectures on even footing.

This chip’s thirst for nguồn has been quenched somewhat by the 7nm process node, too. The Ryzen 9 3900X sits within a 105W TD, và with 12-cores in hand it requires some 210 wattstotal platform nguồn under x264 v5.0 benchmarking. But with a thirst less than the 8-core Ryzen 7 2700X the 7nm process is evidently paying dividends where it counts.

The benefits of this topology are obvious. Yields are less troublesome lớn high-core-count processors, clock speeds are not tethered khổng lồ perfect, or near-perfect, dies, & the Ryzen 9 3900X need not sacrifice tốc độ for multicore performance. Therefore this cpu is not only the ‘megatasker’ champ right now, but the single-threaded prizefighter taking it to hãng sản xuất intel on the gaming front.

AMD Ryzen 9 3900X performance

You can see why intel has been pushing the “real-world gaming” narrative as of late – the Ryzen 3900X royally trounces the hãng intel 9900K in synthetic results. The famed Cinebench R20 benchmark sees the Ryzen 9 3900X take the lead by 41% – a little over 10% for every extra chip core the Ryzen 9 3900X has over the i9 9900K.

The Ryzen 9 3900X also marginally outperforms the hãng intel i9 9900K in Cinebench R15 – despite the latter’s clock speed advantage.

Professional clip workloads should be no worry for the 12-core chip, either. In x264 v5.0, a benchmark that measures just how fast your CPU can encode a 1080p video clip clip, the Ryzen 9 3900X flew past the competition. This benchmark is highly receptive to greater threads, as are many non-gaming workloads, so no real surprise that the 24-threads of the Ryzen 9 3900X comes out on đứng top here.

The Ryzen 9 3900X has the silicon advantage, four whole cores of it.That makes for much of an equitable showdown with Intel’s 8-core i9 9900K in synthetic benchmarks, but once you get into the real crux of gaming benchmarks it becomes afar closer battle with Intel’s Coffee Lake champion.

In Civilisation VI there’s only a fraction of a second between the Ryzen 9 3900X & the Intel chip core i9 9900K with the latter taking the crown by a hair. We’re talking less than one tenth of a second here, folks – 6.88 seconds to lớn Intel’s 6.79 seconds.

If we move onto Total War: Three Kingdoms, this is where we see hãng intel retain the furthest lead over AMD’s latest chips. And with good reason. Benchmarking suggests this game is fond offrequency muscle, not bộ vi xử lý core count, & that sees the 5GHz turbo of the i9 9900K move considerably ahead in 1080p, CPU-intensive gaming. The Ryzen 9 3900X is close, however, and making great strides beyond the capability of the Zen+ Ryzen 7 2700X. With near-identical scores between the 12-core và 8-core Ryzen 9 và Ryzen 7, these chips’ two scores are a 14% increase on those of the Ryzen 7 2700X. That’s bang on the touted instruction per clock (IPC) gains with Zen 2. It’s not all about process, people.

For the most part AMD’s cpu lands just beneath Intel’s processors, if only by a small margin. That’s especially the case as you move up into 1440p and, especially, 4K gaming. With the burden of gaming performance squarely on the graphics card at high resolutions, which CPU you’ve chosen is of lesser importance amongst the top-tier chips from either side.

Assassin’s Creed: Odyssey at 1440p sees just two frames between the Ryzen 9 3900X & the hãng sản xuất intel i9 9900K, with hãng intel gaining further in minimum frame times. The Ryzen 9 3900X does just scrape the win in average fps over the i7 9700K, however. A mighty win for AMD’s IPC catch-up. In Far Cry New Dawn at 4K, each CPU sits only a couple of frames of one another – và well withinmargin of error.

AMD Ryzen 9 3900X verdict

With gaming performance swiftly on the rise, AMD is yet again showing its transcendent will to lớn develop at pace và in the right areas. The 3900X is not a straight gaming chip, và few would’ve dreamed of an affordable 12-core gaming chip only half a decade ago. Yetthe smart blend of CCD topology và swift process node adoption (courtesy of TSMC) allows AMD to offer both multi-core numbers và single-threaded, high clock tốc độ performance in 2019 without breaking the bank.

And that age-old gamingperformance deltabetween the two rivals’ chips doesn’t look quite so insurmountable anymore. While AMD still can’t claim record-breaking gaming performance, it’s reached a cấp độ of parity at which point it’s no longer much of a detriment, either.
