AMD Announces the Ryzen Embedded R1000 SoC Series
At the Taiwan Embedded Forum, AMD announced the Ryzen embedded product family is growing with the new AMD Ryzen Embedded R1000 SoC. Building upon the success of the Ryzen Embedded V1000 SoC, the AMD Ryzen Embedded R1000 SoC provides embedded customers with dual core, quad-threaded performance...

TLDR
- R1505G is embedded version of Athlon 300U (having Identical performance)
- Raven Ridge uses 14LPP+. Ryzen 3200U/Athlon 300U use a die orientated for quasi-Raven2 operation with 14nm (no plus) transistors. Ryzen 3300U and up use a die orientated at replacing Raven Ridge's 14LPP+, called "12LP Boost Plus".
- The die is an intermediate version between 14nm Zen based processor & 12nm Zen+ based processor.
It is still 14nm anyway.
Awesome deal, OP! I just joined to say thank you. The current lowest price for automatically accepted best offer from the seller for these is $100. I tried $99 but $100 was the lowest they would go.
Yeah... VCN is a low wattage beast for 4K. I would double check your settings there if I were you. Just to give you a feel for its transcode power, you should easily be able to do 3 real-time 4K transcodes with VCN. Something's not quite right if it's going that slow.What about transcoding on Handbrake (which can support AMD VCE/VCN video encoding)?
Well, CPU usage is high but the GPU usage isn't that much. AMD has to put some serious work in to catch up to nVidia and Intel - performance were not great and the CPU usage is through the roof.
In fact, I got this to run Plex since someone just got Ryzen APU transcoding working in Linux. That with Openmediavault should make this a cool little tech toy.
Really? So these come with TOTL AX200 cards installed? Wow... I noticed some higher-end SKUs of the T640 with the AX200, but I didn't expect it here. That's a major step up over the default Intel Wireless-AC 9260.
This is not entirely true. True, Raven Ridge at its inception and early on was using an intermediate version of manufacturing process between 14nm and 12nm, so having used a 2400G, I can tell you it would accurately appear here in CPU-Z as 14nm, not 12nm, to reflect this. However, CPU-Z can discernibly read the CPU firmware and then generally ascertain the production node based on that valuable piece of baked-in information. That's why, for example, Ryzen 5 1600's that are AF revision show up accurately as 12nm in CPU-Z.I found the fun detail answer here.

To confirm, then, the R1505G is 12nm.
遠坂小町@Komachi on Twitter: "@1969yuri1969 RAVEN 2 is 12nm/2C4T Die. I don't know if the Athlon 200 Series will switch from Cut-Down RAVEN1 to RAVEN2, but it certainly will appear for Embedded. That is, I don't yet know if it will appear for consumers. PS : It's AMD Ryzen Embedded R1606G/R1505G" / Twitter
EDIT: Or not. I spoke too soon, thinking Komachi, who is generally spot on with this sort of thing, was right. See below for the lowdown. It appears RAVEN2, which is a R1000 series embedded products, uses the same firmware blob as 12nm Picasso. So that would explain the CPU-Z misreading of it as 12nm. What has happened here is AMD has backported most if not all of 12nm Picasso design elements to RAVEN2 on 14nm, hence the need to use the same firmware. Therefore, they are applying that firmware to this 2-core RAVEN2 product. So this processor likely carries Picasso's microarchitectural enhancements without the minor physical efficiency advantages of the 12nm process that Picasso had gained along the way. Talk about a Franken-chip!
And to doubly confirm this error, the Athlon 3000G (also RAVEN2) is misreported in the same way.

Just wanted to add that the T640 from this secondary seller also had the serial port and AX200 wifi card. The packaging was much different than the one I bought from the seller that OP initially referenced but the PC itself was pretty much identical.
Great buy either way!
Confirming my suspicions, HDR is also tested as working. It is just as I thought it might be: HP is only testing and/or paying for official certification for DisplayPort 1.2, but the device itself is fully DisplayPort 1.4 capable. Back in 2018, a similar situation occurred of stated motherboard certification versus real world processor support with Ryzen 2000 APUs and HDMI 2.0. Likewise here, the reality is the processor fully supports DisplayPort 1.4 meaning it governs DisplayPort compliance regardless of the motherboard or the labeled certification. So as long as you have a DisplayPort 1.4 to HDMI 2.0 with HDR adapter, you can passthrough HDR content without error.
Definitely good to know - it’s essentially the same situation with the max RAM size - it’s certified to 32GB abut will work all the way to 64. Now if only we can see if the t640 can do SRIOV the same way the t740 can/will.
@WANg I wonder whether t740 support DDR4 32GB CAS16 1.35v SODIMMs? Crucial Ballistix 3200 MHz DDR4 DRAM Laptop Gaming Memory Kit 64GB (32GBx2) CL16 BL2K32G32C16S4B - Newegg.com.
Do you know anything about it?
Planning to get 2 of these with my t740. Or should i stick to 1.2v RAM to be safe? Something like Crucial 64GB Kit (32GBx2) DDR4 3200 MT/s CL22 SODIMM - Newegg.com.

Hi Foss,
Just a quick heads-up that I've successfully used both the following 2 x 32GB DIMMs in my T740s:
HyperX Kingston 32GB 2666MHz DDR4 CL16 SODIMM Impact (HX426S16IB/32)
Viper Steel Series DDR4 32GB (1 x 32GB) 3000 MHz SODIMM Single
Note that one of the Viper SODIMMs was faulty, but I was testing with a 24-hour run of MemTestx86 against these, to avoid exactly this kind of issue, so I did a simple return and re-order, and all was well with the replacement SODIMM.
Thanks. That is 1.2v and 1.25v parts. The one i posted says 1.35v in the spec and i wonder if that will create any issues. Seems 1.25v worked with your Viper worked fine though!
I think you'll be alright. From my very cursory research on this, DDR4 runs by default at 1.2, and XMP can increase the voltage in steps to handle the higher clock speeds, as signal degradation is more of an issue at high clock/low voltage. That said, I'm pretty sure these machines will only run the RAM at 2666 Mhz so any potential speeds beyond this are probably wasted, at least on this platform. However, if you move those SIMMS to a higher-end laptop down the road, you may reap the reward.
"By default, DDR4 runs at 1.2v, while many memory module kits are rated to run at around 1.35v with XMP. Raise your voltage slowly until your system is stable; we recommend not going above 1.4v to be safe."

Edit: at the end of the day, I'd recommend making you have free, and non-contestable returns, as getting incompatible or defective hardware is more likely to be an issue. From what I remember, NewEgg isn't well-know for those qualities, so you may want to review your supply choice. my 2c, for what it's worth.

Thanks. I figured out they will not run CL16 anyway so i'm going the safe route with 1.2v SODIMM.
On Ryzen Embedded V1756B - AMD - WikiChip it states suppored memory speed is DDR4 3200. Will test with the actual one i have here! Thanks.

How should compatibility be with this new 3200MHz Cl16 1.35V 2x8GB SODIMM kit from Mushkin for the T640 (note: this is the T640 thread)? It is a brand new kit that Mushkin just released that has yet to have listed on their website's product listing. Processor-wise, I already know that I don't have to worry since Ryzen's DRAM controller is common between desktop and laptop APU products and it can easily handle X.M.P. desktop memory kits with voltages up to 1.5V.

@Hifihedgehog Are you sure? I was also curious as which one of the SODIMMs to get and read somewhere on Reddit that these CPUs would probably run CL22 and down to 1.2v if you were using low CAS DIMMs like the one you listed. In other words, it would be waste to pay higher price for such DIMMs to be used with t640/t740. But this really needs to be confirmed!
Perhaps just buy a cheap (if there is any 4GB) CL16 DIMM and test out..

Well, the reason I ask is the cheapest 2x8GB DDR4 SODIMM kit on Amazon right now happens to be Mushkin's 3200MHz Cl16 kit. So it's no loss to me if it does drop down since I paid less anyway than the 1.2V 3200MHz Cl22 kits. I'm not certain how HP's BIOS is programmed to react to memory with tight timings and higher voltages, but we will see.
I wonder, could this be paired with an ADT-Link M.2 Key M to PCI Express adapter and a dual SFP+ NIC to create a 10 GbE router?
In theory, yes. But you'll lose your NVMe (boot from USB3, then...?), I am not sure if it works, and you'll still have to figure out a way to "ghetto glue" a dual 10Gbit NIC to the chassis, and figure out a way to cool it. My past experience with SolarFlare dual 10GbE cards tells me that they are not cool running whatsoever.
Of course, if it works, the real benefactor will be the t740 thin client down the line. You still have an M.2 SATA port next to the NVMe, and if it can be used to drive a quadport 1GbE card and a 40GbE dual on the built-in PCIe 30 x8, and that would be super-useful for pfsense.
Ooooof. The ghetto glue involved will not be pretty.
it’s ECC compatible (as in, if you put ECC in there it’ll function) but the actual error correction is probably not done - dmidecode (in a Linux) did not show any parity checking on the installed RAM.
