AMD Second-generation Ryzen "Pinnacle Ridge" Confirmed to Support AM4
AMD, in an interview with Overclockers UK (OCUK), confirmed that its second-generation Ryzen desktop processors will support the existing AM4 socket, so current Ryzen platform users can seamlessly upgrade to the new processors, with a BIOS update. Most current AM4 socket motherboards will require BIOS updates to support Ryzen "Raven Ridge" desktop APUs, and Ryzen "Pinnacle Ridge" CPUs, as the two require an update to the latest AGESA 1.0.0.7 version. In the interview, AMD representative James Prior confirmed that the company plans to keep AM4 its mainstream-desktop processor socket all the way up to 2020, which means at least another two to three generations of processors for it.
The next generation is "Pinnacle Ridge," which is rumored to be an optical-shrink of the "Summit Ridge" silicon to the 12 nm process, enabling higher clock speeds. The decision to keep AM4 doesn't mean the company's 300-series chipset will be made to stretch over 3 years. The company could release newer chipsets, particularly to address 300-series chipset's main shortcoming, just 6-8 older PCI-Express gen 2.0 general purpose lanes (while Intel chipsets put out up to 24 gen 3.0 lanes).

There's a reason we have choices. Sorry I built my rig the way I wanted. At least Boards don't have to be upgraded every other year to support a new cpu, easy drop ins Like Super 7 was in the day, on top of that I'm not in debt because of a build. On another note there are better things in life than being at the computer 24/7.
If its covering 2/3 of the new system wouldn't it be more "friendly" to advise them towards a current gen system with all the benefits you spouted. Doesn't need to be top end.
Seams so contradictory
There are almost always unused or non-essential pins in the socket, which is why often people with broken pins on the cpu / mobo is still able to run their PC seemingly without issue.
I used to to give away my old parts, as I'm not cheap like you...
and yet threadripper, which destroys Intel in PCIe lane count. FYI most consumer motherboards don't even have 2 M.2 slots so you are going to need to buy something like a threadripper regardless.
"The bad is you won't get any other system improvements."
What? You do realize that AMD is still going to release a new chipset with each new Zen generation right? Other system improvements are completely possible.
"Ok, 10Gbps Ethernet can still go via the chipset, but might be a bottlenecked slightly, but other things will be far too limited to go through there."
Um no, 10Gbps is completely possible with zero bottleneck. The ASRock x370 gaming pro has a 5Gbps LAN right now.
I like to hear tech news in general. It's very easy to not read it judging by the title of the article. ;) Freesync with 1080 like performance. That's a pretty good reason if you can find them priced accordingly.
Really, as far a DT platforms go, Intel has been very reasonable with socket changes and compatibility overall.
Correct me if I'm wrong though as the specifics slip my mind at the moment. :)
It's exactly these new features and system improvements that will push current Ryzen users to update the mobo as well - not just the CPU. So the AM4 longevity is a little overrated. Says you?
I'm looking at the top of the range ASRock X370 Fatal1ty Professional. Next to the ASRock Z370 Fatal1ty Professional, which is just $40 more, it looks like it came from a lower segment.
Z370 has 10Gbit LAN and dual 1GBit (X370: 5GBit + 1GBit)
Z370 has 3 fast M.2 (X370: 1 fast, 1 slow)
Z370 has 3 PCIe 3.0 x16 (X370: 2)
Z370 has 3 USB 3.1 Gen2 (X370: 2)
The next year or two we'll see PCIe 4.0 (or 5.0) getting adopted so the question of lanes becomes moot. Especially for AMD since Ryzen is an SoC, Intel as we know is limited by DMI.
I have a 1080ti for gaming and 4 vega64s for compute. Why? Because that gives me 100Tflops of tensorflow compute. Vega is probably rop limited for gaming... but it excels at compute.
Hoping the die shrink leads to higher clocked R7s.
Ryzen = 24 lanes = 16 for Graphics, 4 for NVMe, 4 for link to Chipset
Intel CFL = 20 lanes = 16 for Graphics, 4 for link to Chipset
With Intel, none of the NVMe drives are running from the CPU itself because of the limited PCI-E lanes from the CPU.
So, there are two options:
1.) We were talking about the PCI-E lanes coming off the CPU, in which case you were wrong in your statement about AMD being too stingy, because they obviously were not since they have more lanes than Intel.
OR
2.) We were talking about the lanes coming from the chipset(we were) in which AMD has the same bandwidth between the chipset and the CPU, which means they have plenty of room to expand the lanes provided by the chipset and you were wrong.
You can pick which situations you think we were actually talking about, but either way, you were wrong. Except it hasn't really been shown to be a bottleneck in Intel's system, not that I've seen. I've run NVMe and 10Gb/s network through the chipset just fine. The link between the CPU and chipset is a 31.5Gb/s link. If you use 10Gb/s ethernet, that still leaves 21.5Gb/s for everything else. That is still an insane amount of bandwidth. Yeah, that might slightly bottleneck the fastest NVMe drives, but not to a noticeable degree. It's still 2.6GB/s of bandwidth! That's enough for an NVMe drive, a SATA storage drive, and some USB 3.0 ports to be active without any noticeable slowdown. Yes, indeed it would be nice if people wouldn't post without knowing where the discussion started...:rolleyes:
Because, the fact is we were talking about the chipset lanes. Nothing in your original post suggests you, for whatever reason, were talking about the CPU other than you stating they need a new socket for more PCI-E lanes, which doesn't make any sense when you actually know what you're talking about. No one before you was talking about the CPU lanes, and you never mention in your post you were talking about the CPU. Everyone else in this thread is talking about the chipset.
And the fact is, AMD could actually make the link to the Chipset twice as fast an Intel very easily. They have 8 extra PCI-E lanes on their CPU while Intel only has 4. Right now, AMD divides the 8 lanes as 4+4, 4 for the chipset and 4 for an NVMe drive. However, if they develop a more capable chipset with more PCI-E 3.0 lanes, they could take the 4 lanes currently used for NVMe connection and instead use those for the connection to the chipset, giving twice the bandwidth between the CPU and chipset that Intel has. That would be 63Gb/s, or 7.8GB/s. More than enough for an NVMe RAID array, 10Gb/s ethernet, all the USB ports you would want, and plenty of SATA ports.
This likely could be done with the current processors too. The motherboard would decided where the PCI-E lanes are directed. If a CPU is put in an older board, then the current configuration is used. If the CPU is put in a motherboard with a newer chipset, then all 8 lanes are used for the chipset connection, and the chipset then provides more lanes for NVMe and other expansion cards.
But now, the overwhelming majority of people do not upgrade just their CPU. So ensuring that feature isn't something the CPU manufacturers have to consider anymore. Even gamers and people that build their own systems rarely upgrade just the CPU because they want the new generation. Yes, there are some, a small some, that do it to because they originally bought a Pentium 2c/2t and want to upgrade to an i5 or i7, or an FX 4c/4t and wand to upgrade to 8c/8t, etc. But at the same time, a large reasoning for the lack of interested to upgrade to new new generation CPU is the gap between generations has greatly decreased. Back in the day, there was a pretty significant bump in performance going from a 386 to a 486, and that is why a pin compatible 486 was released for 386 motherboards. But today, we see tiny generation improvements. I mean, that's why I'm still running a 4 generation old i7 in my gaming rig. There was no compelling improvement for me to upgrade to the new generations, even if they were compatible with my motherboard, it really wouldn't have even been worth the wasted effort of pulling things apart to put in a new processor. An hour of my time isn't worth a performance improvement that I won't even notice. And I'm an enthusiast and a gamer. Normal people don't upgrade their CPUs. And in the 15+ years I've been working in and running computer repair shops, I've only ever had one person come in asking for just a cpu upgrade. While most people would rather just go out and buy a whole new computer than spend the money on a CPU upgrade.

Now, whether the socket itself needed changing is up for debate: some people say yes, others say no. I personally reckon Intel wasn't happy with the safety margin of an unmodified LGA1151 socket, which resulted in the update. The basic engineering premise is sound however: more power leads to more current (since you never want to raise the voltage), which leads to more power pins. Adding more power pins is exactly what Intel did with the updated Z370-based 1151 boards.
