Fabricated posted:Shame they went with vcache on only one CCD leading to this goofy stuff. I was kinda hoping for the 3d cache bump for games and also having the big pile of threads for stuff like VMs and some other work stuff I do but this stuff is a pretty hacky workaround. Dr. Video Games 0031 posted:So, like every other CPU release? Cygni posted:I feel like AMD has primarily limited their parts and established segmentation with core numbers the last few generations, especially with Zen4 mostly boosting as high as it can and bouncing off the temp limiter most of the time. But of course... those core limitations were likely artificial for the 6/4 core parts themselves, so. alex314 posted:Some people also need all the cores. If you've got cash, and all you do is either game or do "light HEDT" workloads then 7950x3d sounds amazing. But as Steve mentioned it's better to wait until April to decide. Even if one CCD part is bad then 16core will have better software support. Outside of synthetic benchmarking (and HPC), getting completely linear scaling out of more cores - even while doing things like compiling an OS or ~50000 pieces of third-party software for it (both of which I do semi regularly) doesn't scale linearly.

Combat Pretzel posted:Tell me about DDR5 memory overclocking. When there's one module with Hynix M dies that's clocked fairly high and tight, if I were to take a DDR5-4800 stick with the same Hynix M dies, I could more or less transfer the timings over? Or does the PMIC throw a curve ball here? This is mostly about making some Kingston DDR5-4800 ECC sticks faster. As far as I'm aware, there's not much binning happening with DDR5 yet, and most sticks with the same modules should have the same overclocking headroom. I've seen plenty of people overclock DDR5-4800 to really high speeds. That said, I don't know how ECC affects things.

Re: Consoles and AMD, it's been big for them for quite a while. If you wanna go back and dig though financials, you're looking for the "Semicustom" division. In other news, Phoronix has put out 7950X3D benchmarks. There are three take-aways for me, when looking at the sci/eng workloads. One: if you're doing CFD, get thyself an X3D chip.  Two: fuckin' lol at Intel burning 2.7X the power to do maybe 20% worse?  Three: To my surprise, the GROMACS workload, which is most similar to what I task my machines with, does not show an impressive uplift from vcache. I might just go with 7950Xs in my next upgrade cycle.  Full article: https://www.phoronix.com/review/amd-ryzen9-7950x3d-linux/11

FuturePastNow posted:XBox Game Bar thinks Discord is a game and I've got that running 24/7 so I guess I'd just never have that second chiplet lol That's not how it works. 1) It'll need to be registered in that driver with a core type preference. 2) If for some reason Discord was registered as preferring cache it would be parked in the cache ccd. 'Parking' is essentially setting processor affinity for that process. If it is registered as preferring cache then the process will stay in cores 0-7 (or 0-15 I guess with HT) and never migrate to the other CCD. The parking is a fine solution except if there is some game out there that like cache and can actually saturate more then 8 cores with threads. Anyways, video from a server guy explaining parking in more detail https://www.youtube.com/watch?v=omTigqfWNu0 lamentable dustman fucked around with this message at 22:35 on Mar 1, 2023 |

I decided the fomo was real and picked up a 5800X3D at $309. I have a 5800X so it won't be a huge upgrade, but it's not a waste since I can put that in my other AM4 board which has a 1700X. The first gen ryzens aren't included in Windows 11 support because windows 11 support is arbitrary. The 1700X may end up as a VM server when I upgrade those.

Source, I use a 1700 as a VM server/testbed with win11 Yeah, I've been testing 11 on a haswell machine, so I'm aware. I just figure I'll end up doing some possible future proofing for the potential issues MS will cause after Windows 10 support ends in October of 2025. My current VM servers are all on VMWare ESXi; one's an FX8300, and I have two LGA1366 supermicro boards with dual 6 core xeons. Those are roughly like a first gen core i7 or something, though, so not that great. That's all pretty old stuff, though, so the 1700X might end up replacing one of them eventually. So far the hardware has been holding up on all of them since 2015-2016, although I think there's one fan going bad and a disk started going bad a little while ago that I'm about to swap out for an SSD. None of these VM servers do a lot of heavy lifting.

Are we all going the same route? replace "1700x" with "2600x" and this is exactly my situation (also I play games that will definitely benefit A LOT from the extra cache). After hearing that 5800x3ds are not produced anymore so what's left in retail channels is all we're going to get, and seeing that there's been no clearance sale with the new 3d chips release (and it costs now about what a 5800x costed last year - I could've waited until the new 7800X3D comes out in April, but by then there might be no 5800x3ds left...), I hedged my bets and got one now, considering I just upgraded my GPU for a truly disgusting amount of money and I'm not going to also spend the full amount for a new mobo+new cpu+ddr5 ram right now.

There was a pretty good bundle with a 7700X on newegg but it sold out within a few hours of going live. There are a handful of bundles for the 7600X that discount the price by between $50 - $75, but none of them are particularly good deals due to only including motherboards and/or ram that were overpriced to begin with.

One of those to where if I wanted to upgrade to a 3rd gen. Ryzen it was a one-way trip with the BIOS update, and even then it was hit or miss. I had no issues at all with Win 11 on a 1600. Main reason I upgraded as I did was that Asus board sucked with the memory timings. I never could get XMP to run stable. For those that have access to a Micro Center, they have a bundle that includes a 7900x, Asus motherboard, and 32 gig DDR5-6000 for $600, or drop it down to a 7700x for $500 (MSI motherboard on this one). These are in-store only is the major downside.

I'm still not sure whether go red or blue this time, and all that stops me from getting Ryzen 7... is my lovely history with x370 and R7-1700. I'll probably go with AMD since I like the power efficiency they deliver, or just decide to keep 3700x as my main system for a bit more. I guess there's zero chance for new chipsets to be launched this year?

So that's really to say that entry-level motherboards should be out this year. The actual first-gen AM5 chipsets are already here and are a whopping 5 (X670) or 4 (B650) months old.

The memory controller in the zen/zen+ chips was a bit poo poo, and there's likely nothing wrong with your motherboard if you want to upgrade it to zen 3. I moved from a zen+ with RAM that couldn't do more than 2866mhz to zen 3 with 3600CL16 memory on the same B450 motherboard and it runs fine now.

And the bundle sounds like a nice enough upgrade from my coffee lake setup

Apparently we are. I'd planned to coast by with my 3600 until Zen 5 or Intel's 14x00 series were released, but I need a new GPU. Benchmarks indicate it would bottleneck any of the new ones, so I settled for a 5800X3D rather than having to pay for a whole new mobo and RAM.

Did I misinterpret or was that a weird edge case that's unlikely to come up. It really is arbitrary afaik, many 6th and 7th gen intel CPUs/motherboard chipsets support the hardware features that Windows 11 wants but are excluded from their list of supported CPUs. My guess is that unsupported CPUs will be able to run it until MS does something, sometime, and then we'll see what happens. Doing small business IT the only upside is that some companies have been clinging to 3rd and 4th gen intel desktops with hard drives and I've let them all know they'll need to upgrade those between now and 2025 which helps (forces) them to plan for upgrades. SSDs will probably be more noticeable improvements to their day to day Word/Excel/Edge usage than the CPUs, however.
