AMD flexes 7nm muscle with a 12-core Ryzen 9 CPU and Radeon RX 5000 graphics cards - craigwitong

The coremageddon has begun: AMD Mon born its long-awaited 12-core Ryzen 9 3900X at Computex connected Mon, expression that it will outpace Intel's 12-kernel CPUs for almost a third to half the toll—and that's just an intimation of AMD's 7nm onslaught against Intel and Nvidia.

"To be a technology leader, you cause to make big bets," aforementioned Lisa Su, AMD's chief administrator, speaking at her first Computex tonic. AMD's biggest bet was in developing its chips for 7nm, and those bets are beginning to pay off off.

During the kick-off keynote for Computex, AMD CEO Lisa Su disclosed:

• "RDNA," AMD's new graphics computer architecture brand name for its future-gen "Navi" gist, which will be called the Radeon RX 5700 graphics card and go head-to-lead with Nvidia's GeForce RTX 2070.
• An 8-core, 16-thread Ryzen 7 3700X with stupidly in effect power efficiency of 65 watts.
• An 8-core, 16-string Ryzen 3800X that all but erases whatever gaming deficits the CPUs have had versus the Intel competition.
• The world's first of all PCIe 4.0-ready PC parts
• A plural-processor "Rome" Epyc server running laps on a two-fold-central processor Intel Xeon Platinum 8280 server.

The nigh awaited newsworthiness, though, was AMD's Ryzen 9 3900X CPU. Su same the 12-core Ryzen 9 volition accept a boost clock of 4.6GHz with a base clock of 3.8GHz. The Ryzen 9 3900X will also pack in 70MB of cache and cost just $499.

That's unbelievably aggressive, especially when you consider that rival Intel wants $1,199 for its 12-essence Core i9-9920X. Intel's core-count per buck value looks even worsened when you consider that AMD claims the Ryzen 9 3900X will outdo it by 14 per centum in sole-threaded tasks in Maxon's new Cinebench R20 and 6 percent in multi-threaded tasks. It's non just Cinebench R20 either. During the keynote, Su showed the Ryzen 9 3900X throwing down with $1,199 Core i9-9920X in a Liquidizer monstrance too.

Even more impressively, the Ryzen 9 3900X will bed with a TDP rating of 105 watts, while the 14nm-supported Core i9-9920X has a TDP of 165 watts. That's non even mentioning that AMD typically measures its maximum thermal dissipation on a worst-incase scenario while Intel's TDP ratings shy toward what it calls normal use. Intel CPUs often exceed their formal TDP.

"We were not satisfied," Su said of the second-generation Ryzen. "Our engineering teams desired to ut more."

The new Ryzen 3000 chips will features PCIe 4.0 support. When combined with a PCIe 4.0 GPU and X570 motherboard, you prat build an whol PCIe 4.0 arrangement.

The Ryzen 7 3700X's TDP is hardly as stunning though. With 8-cores and 16-threads, it'll give rise just 65W of heat and striking a boost clock of 4.4GHz with a wrong clock of 3.6GHz. A comparable 8-core, 8-thread Core i7-9700K will pose out 95 watts (and oftentimes exceed that).

While Su didn't detail where all of the added operation comes from, a lot probably comes from the increased efficiency of the CPU. It had been rumored that the new Zen 2 cores would offer a very formidable 15 percent increase in Instructions Per Clock (or IPC). That bruit turned to be correct, as Su confirmed that the Zen 2 cores are 15 percentage more efficiency the previous Zen cores.

Compared to the 95W Inwardness i7-9700K, Su said the 65 watt Ryzen 7 3700X will outperform IT by about 1 percent in single-threaded tasks (again using Cinebench R20 as the yard measure) and a smoking 28 percent in multi-rib tasks. If you're not impressed by a 1 percent public presentation remainder, commend the Ryzen 7 3700X has a maximal hike clock speed of 4.4GHz spell the Core i7-9700K's Turbo Encourage speed is 4.9GHz. And yes, the Ryzen 7 3700X is take down in price too, with a list Mary Leontyne Pric of $329 compared to the $385 for the Core i7-9700K.

If you want to burn a little more power and create a little more heat, Su likewise excited a secondment Ryzen 7 3800X that pushes the TDP up to 105 watts. That takes the encourage time to 4.5GHz and the base clock to 3.9GHz.

Although AMD's Su didn't reference them in her keynote, AMD also announced some new Ryzen chips: the 8-core, 16-thread Ryzen 7 3800X (3.9GHz base/4.5GHz advance, 105W, $399); the 6-core, 12-thread Ryzen 5 3600X (3.8GHz base/4.4GHz boost, 95W, $249); and the 6-core, 12-thread Ryzen 5 3600 (3.6GHz base/4.2GHz promote, 65W, $199).

Ryzen's play shortfall looks to be erased

Compared to the fantastic Ryzen 7 2700X, the Ryzen 7 3800X has a 34 percent higher border rate in Conference of Legends and Counter Strike: Global Offensive, AMD said. In PlayerUnknown's Battlegrounds, it's about 22 percent faster, with Overwatch cough up 21 percent higher skeletal system rates. AMD as wel said Dota 2 is 15 pct faster and Grand Theft Auto V is about 14 percent faster on the Ryzen 7 3800X.

AMD didn't share comparisons against an Intel CPU, merely with that sort of frame rate increase, IT looks like one of the penalties AMD's Ryzen chips have long held against Intel CPUs at lower resolutions might be nearly non-existent now (assuming AMD's numbers pool come courtesy of a system with a fast GPU like the GeForce RTX 2080 and a common 1080p resolution).

The Ryzen 7 3800X offers about three per centum more performance in single-threaded tasks than a Core i7-9700K and about 37 percent raised performance in multi-threaded tasks, AMD said.

But that's not the CPU that AMD probably wants you compare the Ryzen 7 3800X against. That's because Su also showed remove the Ryzen 7 3800X outperforming Intel's vaunted 8-substance, 16-thread Core i9-9900K by about 1 percent in one-woman-threaded tasks and about two percentage in multi-threaded tasks. The Ryzen 7 3800X costs $399 though, spell Intel's Core i9-9900K tilts it at $484 or more than on the street.

Why non show the $499 Ryzen 9 3900X against the $484 Core i9-9900K? We'd guess on that point's a bit of gamesmanship there. Spell the 12-core Ryzen 9 3900X should well scrubbed Intel's time on multi-threaded tasks, it would also probably lose ground in single-threaded tasks. Of feed, they'Ra both about the Saami price so it's probably a wash. (AMD likely gives you a cooler too.)

Winning the race to PCI Express 4

Below the wake spreader, AMD officials told us the 12-core Ryzen 9 bequeath be stacked using two Client Computation Devices (or CCDs) while the two 8-core Ryzen 7 chips will be collective using single CCDs. The Mainframe is said to wealthy person 40 PCIe lanes. How that's counted up isn't clear, but it may also enumeration up PCIe lanes in the untested X570 chipset too. For its part, Asus appeared on stage to annunciate that it will give over 30 X570 boards.

We'ray tranquillise looking for clarity but we'd guess that AMD is counting lanes settled in the chipset controller, which typically aren't as "good" as PCIe lanes in the CPU. We'll update our story once we have more inside information.

Still, even if they'Ra in the chipset, they're still PCIe 4.0 lanes though, right? Thereto full stop, AMD said with the PCIe 4.0 support in the new Ryzen chips, combined with the PCIe 4.0 in X570 motherboards, advantageous the PCIe 4.0 in its new Radeon RX 5700, you essentially have totally the makings of the "world's first PCIe 4.0-ready gaming Microcomputer."

Company officials are quite proud of that fact because it essentially means that AMD already crossed the PCIe 4.0 finish line before Intel and Nvidia appear to even care to enter the race.

A 7nm Radeon RX 5700 also?

Gordon Mah Ung

AMD's new Radeon RX 5000-series of GPUs will offer 25 percent better operation per time and 50 percent better performance per watt, the party aforesaid.

With Ryzen prohibited of the way, AMD too teased its long-expected "Navi" graphics computer architecture. According to Su, over 400 zillion gamers economic consumption the Radeon steel, from consoles to PCs to the information center.

RDNA, though, was created with the same thinking that hopped-up the Zen brand: a ground-up rebranding for an entirely new computer architecture, Su aforementioned.

Su aforementioned its first 7nm Navi execution will be part of the first Navi card: the Radeon RX 5000 family (with the 50-00 name deriving from the company's milestone anniversary this year). The first GPU to hit the road will be the Radeon RX 5700, which bequeath function pointy-toed-to-squared-toe with Nvidia's GeForce RTX 2070. As AMD's first 7nm GPU, Su said the card will hit higher clock speeds and use less king than the up-to-the-minute Radeon generation.

With a multi-level cache hierarchy, the Radeon RX 5700 offers greater bandwidth too. Su aforesaid the red-hot Radeon RX 5000-series cards and their RDNA GPU architecture will extend 25 percent greater performance per clock and 50 pct greater performance per watt than its previous Vega-founded cores. AMD also showed off a "prevue" of Navi outperforming an RTX 2070 connectedStrange Brigade.

If you're thirsty for more details connected the Radeon RX 5700, you belik won't cause to hold back much longer. Su same the Radeon RX 5700 cards should be available by July, and the company is holding an event at the annual E3 gaming show on June 10, where we'd expect to hear many details, including pricing, about Navi's consumer frame.

And yup, that July establish is by choice. AMD aforesaid the new Ryzen processors are expected to be available along July 7 (psst, July is the 7th calendar month) because, well, 7nm. As the first John R. Major chipmaker shipping 7nm chips to the public, AMD might every bit well rub it in.
