Hardware AMD Ryzen 3 3000 Announced with 8-12 CPU Cores & ECC Memory

eva2000 · May 30, 2019

AMD Keynote at Computex 2019 announced a July 7th, 2019 release day for their AMD Ryzen 3 next generation AMD Ryzen 3000 product range with up to 8-12 cpu cores and motherboard manufacturers have server class motherboards to allow AMD Ryzen 3 to support ECC memory! Their AMD Ryzen 9 3900X is just overlapping and stepping on their older AMD ThreadRipper lower product range's toes with 12 cpu cores and 24 cpu threads but at a much cheaper price point

AMD Ryzen 3000 Announced: Five CPUs, 12 Cores for $499, Up to 4.6 GHz, PCIe 4.0, Coming 7/7

ASRock Rack X470D4U AMD Ryzen Server Motherboards - STH

While they only mention up to 12 cpu cores on their Ryzen 9 3900X, there's rumours there's a higher 16 cpu core part ready and waiting to compete with whatever Intel releases.

Today at Computex, AMD CEO Dr. Lisa Su is announcing the raft of processors it will be launching on its new Zen 2 chiplet-based microarchitecture. Among other things, AMD is unveiling its new Ryzen 9 product tier, which it is using for its 12-core Ryzen 9 3900X processor, and which runs at 4.6 GHz boost. All of the five processors will be PCIe 4.0 enabled, and while they are being accompanied by the new X570 chipset launch, they still use the same AM4 socket, meaning some AMD 300 and 400-series motherboards can still be used. We have all the details inside.

Good news for AMD Ryzen ECC memory support for the server and workstation segment, ASRock Rack X470D4U AMD Ryzen Server Motherboards - STH including showing off a ASRock Rack 1U2LW-X470 1U Ryzen Server and ASRock Rack X399D8A-2T Ryzen Threadripper server motherboard. Looks like good candidates for OVH and Hetzner like cloud providers to offer for their dedicated bare metal servers and cheaper alternative to Intel's new Xeon E-2200 Skylake refresh cpus

At Computex 2019, ASRock Rack showed off two AMD Ryzen server motherboards. The ASRock Rack X470D4U and X470D4U2-2L2T both utilize the AMD X470 chipset which means they will also support the new 8 and 12 core 7nm 3rd generation Ryzen partsannounced at Computex 2019. ASRock Rack also has the motherboards in a server platform. As a bonus, the company also showed off the ASRock Rack X399D8A-2T which is a X399-based Threadripper server platform.

ASRock Rack X470D4U
The ASRock Rack X470D4U is a mATX platform that sports a socket AM4 along with the AMD X470 chipset. This allows the motherboard to support first, second, and third generation Ryzen parts according to the company. Four DIMM slots provide up to 64GB DDR4 support using 4x 16GB DIMMs and the company says it will support ECC UDIMMs on the platform.

Yup it's true AMD Ryzen 9 3950X is a 16 core/ 32 cpu thread part coming September, 2019 announced at E3 2019 with their AMD Radeon RX 5700 XT and Radeon RX 5700 GPU release announcements AMD Radeon RX 5700 XT Navi and 16C Ryzen 3950X Launches at E3

Aside from the 16 cores and 32 threads, we can expect a 3.5GHz base and 4.7GHz boost clock with 72MB of cache and only a 105W TDP. Combine this with PCIe Gen4 and one has a very strong platform without a direct Intel counter launched at this point.

AMD says this will be available in September for $749. That is well behind the other launches today which are destined for July 7, 2019 launch.

sweet AMD's Upcoming $750 Ryzen 9 3950X (16C, 32T) Shown Beating Intel's $2,000 i9-9980XE (18C, 36T)

a Geekbench test result has shown AMD's $750, 16 core, 32 thread Ryzen 9 9 3950X beating Intel's 18 core, 36 thread $2,000 i9-9980XE monster. Now, you may be thinking: ok, it beat it because of AMD's announced 4.7 GHz boost, and did so only on single threaded performance, obviously... but you would be wrong.
Click to expand...

The Geekbench scores show AMD's Ryzen 9 3950X delivering 5,868 points in single, and 61,072 points in multicore workloads. Intel's i9-9980XE, on the other hand, scores just 5,391 single core, and 46,876 multicore points (on average and at stock clocks of 3,000 MHz base and 3,400 MHz boost). This is an incredible performance difference (particularly in the multicore score), and was apparently done with an engineering sample for AMD's upcoming chip that didn't even run at its announced 4.3 GHz base and 4.7 GHz boost clocks, but at 3.3 GHz and 4.3 GHz respectively. AMD's 105 W TDP, 16 core chip beats Intel's 185 W TDP, 18 core one... Where has the world come? Take the usual dosage of NaCl, and let's keep things in perspective - even if AMD's Ryzen 9 3950X equals, and doesn't beat, Intel's i9-9980XE, it's still a huge win for the red company. Almost as big a win as that huge stone on Lisa's hand.

Phoronix benchmarks for AMD Ryzen 3700X and AMD Ryzen 3900X AMD Ryzen 7 3700X + Ryzen 9 3900X Offer Incredible Linux Performance But With A Big Caveat Review - Phoronix

After weeks of anticipation, we can now share how the AMD Ryzen 7 3700X and Ryzen 9 3900X performance is under Linux. These first Zen 2 processors do indeed deliver a significant improvement over Zen/Zen+ processors and also battle Intel's latest 14nm CPUs but for Linux users there is one big, unfortunate issue right now.
Click to expand...

To jump straight to the new stuff (Linux support and performance)... On the likes of Ubuntu 18.04 LTS, these new AMD Ryzen 7/9 series 7nm processors deliver incredible performance with the newest AMD X570 motherboards. The support on the likes of Ubuntu 18.04 LTS is great except for possible compatibility issues depending upon the particular motherboard/ASICs employed.
Click to expand...

So what's the problem? On newer Linux distributions, there's a hard regression either within the kernel but more likely some cross-kernel/user-space interaction issue leaving newer Linux distributions unbootable.

While Ubuntu 18.04 LTS and older Linux distributions boot Zen 2, to date I have not been able to successfully boot the likes of Ubuntu 19.04, Manjaro Linux, and Fedora Workstation 31. On all newer Linux distributions I've tried on two different systems built around the Ryzen 7 3700X and Ryzen 9 3900X, each time early in the boot process as soon as trying to start systemd services, all systemd services fail to start.

I've confirmed with AMD they do have an open issue surrounding "5.0.9" (the stock kernel of Ubuntu 19.04) but as of writing hadn't shed any light into the issue. AMD has said their testing has been mostly focused on Ubuntu 18.04 given its LTS status. I've also confirmed the same behavior with some other Windows reviewers who occasionally dabble with Linux.
Click to expand...

Complicating this issue further is that when trying Linux 5.0/5.1/5.2 kernels on Ubuntu 18.04 LTS, they all booted up fine! Hence it doesn't appear to simply be a kernel regression but either some kernel+systemd interaction issue happening just on AMD Ryzen 3000 series processors or some awkward thing happening with the X570 chipset. When asking AMD again on the day prior to launch, they were still investigating the issue and apparently unsure of the root cause at this time.

Looks like AMD Ryzen 3000 series users using Linux should ensure their motherboard bioses are updated for better performance AMD Firmware Update To Bring Boost Performance Optimizations - Phoronix

AMD issued a statement today they are rolling out a new BIOS/firmware update to help with boost clock frequency optimizations.

AMD says they found a firmware situation that reduces boost frequency in some situations. They will be working with their motherboard partners to send out the updates providing these boost performance optimizations.

Preparing to do a big 3-way dedicated server benchmark review with extensive testing between an Intel Xeon E-2276G Coffee Lake vs AMD Ryzen 3600 vs AMD Ryzen 3800X and first need to make sure all cpus turbo boost cpu frequency scalings are correct before I start benchmarking

As such wrote a script to collect cpu's frequency data and chart in out on a per cpu thread as well as all cpu thread basis.

stress 1 cpu thread cpu frequency check on AMD Ryzen 3800X 3.9-4.5Ghz 8C/16T server running CentOS 7.7 64bit. Older CentOS 7.7 3.10 Linux Kernel may not be properly boosting cpu frequency but I will be doing benchmark tests with 3.10 vs 5.3 Linux Kernels as well so can confirm later if newer 5.3 Linux Kernels have proper cpu boost frequency scaling.
