Update 5: Memory Speeds of Up to 5000 MHz?


Some fresh rumours just in this morning as the rumour mill goes into overdrive on the subject of AMD's Ryzen 3000-series over at wccftech (external link). This time, the processor's memory controller has hit the spotlight: it is rumoured to be capable of supporting speeds of up to 5000 MHz. At least in theory, that is. In practice however, these speeds will likely only be achievable by means of overclocking. Furthermore, it seems that an X570 motherboard will be required. Needless to say, PCIe 4.0 support also looks to be on the way and is sure to garner a great deal of interest.


Update 4: Samples Clocked at up to 4.5 GHz?


The first AMD Ryzen 3000 samples have, according to wccftech.com (external link), been achieved by a motherboard manufacturer where they have apparently undergone successful testing. According to the leaked test results, clock frequencies of up to 4,5 GHz have been achieved on Zen2 CPUs. Whether this pertains to the frequencies of a Ryzen 7 3700X or a Ryzen 5 3600X remains unclear. The processor tested is reportedly capable of up to 15 percent more IPC (Instructions per Cycle) than its direct predecessor. For the sake of comparison: Zen+ produced 3% more IPC than Zen.

Furthermore, the memory controller employed in the Zen 2 series of processors has been overhauled to bring support for high-frequency RAM kits operating at up to 4.000 MHz. In conjunction with the new X570 chipset, the new Ryzen CPUs also offer compatibility with 40 new 4th-gen PCIe lanes! Up to 16 lanes are rumoured to be reserved for PCIe slots (8+4+4), while eight lanes are provided for USB 3.1 Gen2 support.

The new Zen2-based Ryzen 3000 series of CPUs will be based on the 7nm node and should appear alongside the AMD Radeon RX 3000 series of graphics cards. It’s reasonable to assume that both 7nm product series will be present and correct at Computex with availability beginning from 7.07.2019.


Update 3: "Valhalla" Coming to X370 & X470 via BIOS Update?


Intriguing news just in regarding AMD's Ryzen 3000-series CPUs. According to wccftech (external link) the first BIOS updates to make X370- and X470 motherboards compatible with AMD's new "Valhalla" CPUs are already in production. Valhalla is the resting place of heroes fallen in battle according to Nordic mythology - and this appears to also be the internal codename AMD has bestowed upon their new Ryzen processors. Officially, Ryzen 3000-series CPUs are named as follows:

  • Mainstream desktop (AM4): Matisse
  • High-end desktop: Castle Peak (TR3000)
  • High-end server: EPYC Rome

The BIOS update is reported to drop just prior to the launch of the Ryzen 3000-CPUs, meaning that users already in possession of X370- or X470-series motherboards will be perfectly placed to enjoy a big upgrade from first gen (Zen) or second gen (Zen+) CPUs to the new third gen (Zen2) processors. Consequently, Ryzen 3700X and the entire 3000-series all retain the socket AM4 standard. News that will also come as a pleasant surprise to many is the fact that even CPU coolers will remain compatible when upgrading to a new Ryzen 3000-series processor.


Update 2: AMD Ryzen 3000: New 7nm Processors Arriving in Summer?


Are AMD's 7nm processors going to be available from 7.07.2019? The rumour mill is churning away once more with news from wccftech.com (external link) and RedGamingTech that July 7th is looking to be the release date for third generation Ryzen 3000-series processors. This date is also looking likely to coincide with the release of new 7nm graphics cards as well, given the significance of the 07.07 date. This date is intended to emphasise the leap forward that switching to the 7nm node means for the company and the industry as a whole. Launching the Radeon VII on 7.02.2019 also demonstrates AMD's previous form when it comes to exploiting clever marketing.

If the new processors such as the Ryzen 7 3700X do prove to arrive on 7.07.2019, then it could indicate that we can look forward to their being introduced in the course of Computex 2019. The Zen 2-based CPU architecture is reported to offer significantly improved IPC performance, more cores and higher clock frequencies. In combination with the 7nm node, the new Ryzen 3000 series is looking like a huge boon for AMD as a whole. Along with the new chipsets, such as the X570, CPUs like the Ryzen 7 3700X will also support PCI Express 4.0. Due to the fact that AMD is sticking with AM4 for now, and that AMD wants their processors to retain backwards compatibility with older AM4 motherboards, some features are likely to be blocked off unless paired with the newest motherboards.


Update 1: Rumour Mill: AMD Ryzen 3000: 12-Core Processor Discovered in Database?


Twitter user “APISAK” (external link) was perusing the benchmark databases when he appears to have stumbled upon an AMD Engineering-Sample. The processor included 12 logical cores and 24 threads. Based on the Zen 2 architecture, it seems to have been clocked at between 3,4 and 3,6 GHz. The socket was listed as AM4, meaning that the listed sample was not merely a Threadripper CPU based on socket TR4.

Whether this leaked sample pertains to the Ryzen 7 3700X or the non-X version remains unclear, although this certainly won’t dampen speculation over the potential performance of the CPU. Apart from increased single-core performance, the number of actual Instructions per Cycle (IPC) has undergone a marked improvement. Since this would appear to be a pre-release test sample, the figures certainly aren’t set in stone just yet. Even a release date for the Ryzen 7 3700X is still to be announced, that said, a launch in the second half of the year seems likely.


Original Post: AMD Ryzen 3000: New in 7 nm with PCIe 4.0


In our blog about AMD's latest products at CES, we covered the initial rumours on the subject of the Ryzen 3000 CPUs. What was previously hearsay however has since proved to be correct.

While CES 2019 in Las Vegas was awestruck at AMD's CEO Lisa Sung releasing a short tech demo of a Ryzen 3000 processor, no one could have predicted that the 8 core 16 thread processor would achieve a CineBench score of 2057 points, trading blows with top models such as the Ryzen 7 2700X and even beating it by up to 15 percent. Aside from the optimised CPU architecture with its new chiplet design, the new 7 nm node is responsible for a significant performance increase compared to the chip's immediate predecessors.

The Zen 2 architecture used in the new Ryzen 3000 CPUs supports, among other things, PCI Express 4.0, albeit only when paired with a 500- series chipset. The new processors are compatible with earlier AM4 motherboards, although they do not include PCIe 4.0 and other new features. Having said that, there is the possibility for individual motherboards to receive BIOS/UEFI updates to upgrade them retrospectively - depending on how the slots are connected physically.

Details such as clock frequencies and the number of cores not yet set in stone, meaning there will likely be plenty of speculation over the coming weeks and months. In our original post we listed the following rumoured specs:

 Cores/ThreadsBase ClockBoost ClockTDP
Ryzen 3 3300 6/12 3.2 GHz 4.0 GHz 50 Watt
Ryzen 3 3300X 6/12 3.5 GHz 4.3 GHz 65 Watt
Ryzen 3 3300G 6/12 3.0 GHz 3.8 GHz 65 Watt
Ryzen 5 3600 8/16 3.6 GHz 4.4 GHz 65 Watt
Ryzen 5 3600X 8/16 4.0 GHz 4.8 GHz 95 Watt
Ryzen 5 3600G 8/16 3.2 GHz 4.0 GHz 95 Watt
Ryzen 7 3700 12/24 3.8 GHz 4.6 GHz 95 Watt
Ryzen 7 3700X 12/24 4.2 GHz 5.0 GHz 105 Watt
Ryzen 9 3800X 16/32 3.9 GHz 4.7 GHz 125 Watt
Ryzen 9 3850X 16/32 4.3 GHz 5.1 GHz 135 Watt
