So does Intel just pay off the OEMs again this time to cockblock AMD, or ... ?

If so, they clearly didn't pay ASUS quite enough considering they went AMD for their flagship prebuilt. Still, this is going into laptops and not mobile phones yet. My prediction is that it'll be at that point that Intel goes: "Throw ALL the money at it!" and I guess we'll see how far cold hard cash and inferior products can get you.

Though if the "Big Navi" rumors are true I suppose they could launch a flagship Radeon RXX 6900XTX EXXXTREME for a thousand bucks a few months ahead of the rest of their RDNA2 lineup. Yeah, part of me was thinking they'd drop the 6900 XT first in like, July (tease at computex), and the 6700 XT and 6500 XT would follow in September and October. With the rumors of Nvidia dropping Ampere in June-August timeframe, if the 6900 XT can at least match the the RTX 3080Ti (tall order), AND launch before, then it'll take the wind out of Ampere's sails. I'm just a little weirded out by the complete lack of mention, they know they're behind Nvidia right now so touting RDNA2 in some way might deflect attention from Ampere. AMD needs to be able to target near linear scaling while dropping power consumption 40-60% to be plausibly inline with Ampere I think, which like...a Bulldozer to Zen moment, and I'd think they'd be more vocal about it. So uh, good luck AMD/RTG.

Interesting to see the two different strategies at work - Ice Lake on 10nm while the rest remains on 14nm as opposed to Renoir on the “old” 7nm while other chips are expected to move to 7nm+ (partial EUV) very soon. Yet Renoir looks like it’ll be competitive in at least some segments and I have little doubt that AMD will be able to ship large amounts of them. I just hope they got their idle power consumption/power gating under control.

Zen3 doesn't need the demo hype Zen2 got, IMHO, and they can talk about it when it's in a more complete state. They avoided dumping too much information and stealing away from the laptop narrative, which is potentially truck fulls of money for them. They'll talk about zen3 and rdna2 at some other event by late q2/early q3 at the latest. Likely they'll have big things to talk about at all major events this year while Intel is "uhh umm" because Intel's strike back won't start until 2021-2022.

Yeah, it makes sense for AMD to just talk about mobile and mobile-related products during the Consumer Electronics Show. We can take the 3990X as a bone thrown to the enthusiasts. The beefy stuff is probably being held for Computex in the summer.

Are multi socket 'desktop' platforms going away since you can now stick 64 cores into a single socket? edit: but then why have massive multi threaded performance on the desktop when you can have twice as massive? I guess there's always a niche need.

making the CPU element itself follow PCIe form factor is kind of bizarre since it means the CPU cooling solution has to squeeze into a 2-slot form factor and exhaust out the top/back, instead of a DAN A4-SFX style solution where both CPU and GPU are back to back and could both suck fresh air through the side panel it's also undoubtedly going to lead to someone plugging it into an actual PCIe slot at some point and probably blowing something up when two CPUs try to master the bus and try to sink each other's signal what they need is basically the PCIe equivalent of the BTX form factor for motherboards where everything is on the opposite side of the PCB relative to normal, and to make the element use that eICP standard.

Shaocaholica posted:Why would it be limited to 2 slots tho? it's not, you could hypothetically leave yourself as many slots of room as you want, but the CPU cooler has to face towards the GPU because that's how the PCIe spec works, versus flipping it the other way and sucking fresh air into the cooler without a card restricting airflow. practically speaking though 2 slots is the only config that anyone really cares about since this is basically a SFF PC and nobody wants a SFF PC that's not small. If you get up into mATX or mITX cube case size then using a standard mobo instead of a backplane thingy is an obvious choice. Paul MaudDib fucked around with this message at 00:08 on Jan 8, 2020 |

taqueso posted:If you could pop 4 CPU modules and 4 GPU modules into an ATX sized backplane I think people would be interested. "backplane" is a little misleading because you'd basically have slots like: Acpu-Agpu Bcpu-Bgpu Ccpu-Cgpu Dcpu-Dgpu with no interconnection between A/B/C/D like you would in a backplane. In other words it's not like you would have 8 slots that all interconnect, that would not be something you could do with off-the-shelf PCIe spec hardware. Even if you could, they would interfere with each other's bus bandwidth anyway. So effectively what you would have is 4 ghost canyon nucs that happen to share a single case and a single PCB for their respective backplanes. cyber cafes might like it I guess. Not really seeing a huge advantage vs taking a 3960X and putting 4 GPUs in it and virtualizing though (apart from looking glass being a mess I guess). Or just having 4 separate pcs in some cheapass cases, the case isn't the expensive part there anyway. Paul MaudDib fucked around with this message at 00:22 on Jan 8, 2020 |

I guess you need a way to have the CPU/chipset able to be a slave on some lanes and a master on others. Then you could build a ring or matrix of connections between CPUs.

Then you could build a ring or matrix of connections between CPUs. that's a pretty big mod that would require both hardware and software changes. if we're doing non-standard hardware configs (this is no longer PCIe) then how 'bout we start with putting the CPU board the right way around?  the end state of having multiple CPU/GPU modules that network over a PCIe-like protocol is cool though. just a lot of work to get there. you could hypothetically do a backplane using off-the-shelf PCIe devices with some kind of switching chip I guess, with all the slots wired to talk to the switch and the switch deciding what gets to talk to what, but something that can switch PCIe slots at full speed (even in a latched configuration/not changing in realtime) sounds expensive. one interesting application of having multiple CPUs/GPUs on a plain old backplane would be for benchmarking though. You could plug four different CPUs and four different GPUs in at a time, and only boot one pair of them at a time. That would make it vastly easier to do the kinds of testing "batches" that reviewers need to do, where you test 27 different kinds of GPUs paired with 14 different CPUs or whatever. You could have them all plugged in and have some sort of BMC that can control which pair gets combined, you boot from an iscsi image and run an automated test script, then move to the next hardware combination. just automate the poo poo out of everything Paul MaudDib fucked around with this message at 00:40 on Jan 8, 2020 |

Yeah I was thinking hypothetically, not ghost canyon specifically. I think you should be able to glue things together with PLX pcie chips so each CPU would devote some lanes to a set of PLX endpoints that each connect to a second PLX chip that is an endpoint for another CPU. Then you get to write a linux driver/numa thing. Oh and figure out what the glue between the PLXs is. Maybe an FPGA.

taqueso posted:That's a good idea. Especially the automation part you expanded on. I've thought of using RDMA to do that. PCIe traffic is just DMA anyway, RDMA lets you talk to one device and have it dump your traffic onto another PCIe bus in another system. So basically software-defined PCIe configurations across RDMA switching. Basically virtualize your CPU+OS on one server and virtualize your GPU on another server and have them connected by Infiniband RDMA. In principle you should be able to treat it like they were physically plugged together but what your PC thinks is a "GPU" is actually an RDMA device that portals the DMA traffic over to the other machine and dumps it onto the PCIe bus there, as if they were physically connected (plus a little bit of latency). There could conceivably be an InfiniBand switch in the middle. Conceptually seems like it should be possible but I'm 99% sure the software to do that doesn't exist in today's hypervisors. It's also an open question how much the latency would hurt as far as gaming, IB guarantees very low latency due to its switched-fabric nature (IB EDR is about 0.5 usec) but it's non-zero.

Multi socket is niche. HPC is one giant fabric designed to interconnect thousands of nodes. Unless you're Chinese and 8p servers are lucky but 4p aren't there's not much to gain by going up in sockets. Especially since epyc can address 4tb, so only really high memory dbs need the 4p memory addressing

Shaocaholica posted:Blade servers but in a smaller format, for kids. Babys first server rack. Honestly, I think they're slavishly holding to PCI spec just a little too much. Imagine, if you would, a world where said.... what's it called Ghost Canyon? NUC were built on the opposite side of the PCB instead, sitting on top instead of hanging down. You could put your graphics card right up against the back of the NUC (plus a little room so that heat coming off the backplate of the GPU doesn't radiate over to the GPU) but have so much better ventilation and airflow for your NUC. Like an ITX ultra-SFF case, but with much shorter PCIe runs, and a hard riser instead of a well-shielded flexible one.
