When will external infinity fabric work for video card versions ? So you can seamlessly join (say) 10x 1080ti's and play some Crysis in 16k, should you really be that bored and well off.
"When will external infinity fabric work for video card versions ?"
Don't expect it any time soon. These custom fabrics are for HPC use where the entire motherboard layout can be customized for the specific processors being used. This is the opposite of standardized PC plug & play functionality.
1080ti is sadly limited to the maximum bandwidth of PCIe 3 x16 interface.
Infinity Fabric is 32.5% faster than PCIe 3 1080ti is limited to (10.6 GT/s vs. 8 GT/s). Per x16 link, that is, number of links depends on the CPU in question.
BS on that, Nv artificially limits things via drivers and such Infinity Fabric is WAY higher speed than any current GPU uses over PCI-E versions, so if 1080Ti can operate "perfectly" over PCI-E 3.0 speeds than Infinity Fabric at an approximate 2-3x the throughput cannot "limit" the performance either.
Infinity Fabric is AMD so likely it will never happen with Nv support, seeing as Nv absolutely did not want any of the advanced features Vulkan or DX12 brings to the table (because it would mean they cannot always screw with the software stacks to make it act as if their GPU was even better than it was)
Also Nv does NOT want multi-gpu usage ability because it can limit potential sales of their most $$$$$ GPU for any reason.
anyways external infinity fabric, I do not see this happening any time soon (or at all) for anything but AMD specific hardware (for many reasons)
they all seem to want to keep everything proprietary BS, everyone but AMD IMO who seem to be wanting to get as much open source, everyone can use no problem, but Intel, Nv, Apple, MSFT want none of that because it means less $$$$$$$ being gouged from the proprietary crud they pull ^.^
I am surprised they are still using GF for 7nm. Given how capacity constraint they are, wouldn't moving the whole GPU lineup to TSMC makes more sense ? Or may be I am guessing porting VEGA from GF 14nm to GF 7nm is a lot easier / economical.
I really hope GPU maker will split the GPU design between Gamer and GPGPU. So GPU prices will stay normal.
Well it is literally the first sentence in the article.

This seems to be edited out. I'd be surprised if they spent the extra money to get Vega on 7nm early on GF (and get the process working) and then turn around and use TSMC (although they might eventually move things over there, I doubt it will be still a new process when they do).
Even if they had contractual issues with GloFo, they'd still be able to hand them enough CPU orders to cover any GPU shortfall.
The real problem about AMD is that the "gamer" market for them is pretty much zero. ALUs are huge (so "gamer" for pretty casual levels of "gamer", but that might help push the base level for game design), and GPGPU is apparently a big push. But I don't see any reason for them to push "gamer".
Understand AMD makes products where is the biggest demand (machine learning) and $$$ but ignoring gamers is not very cool. Vega was very average and nothing new coming in 2018 is very disappointing. I don't want to be buying mid range GPU from NV for $500+ because there is no pressure from AMD. C'mon AMD!
AMD wil be able/are using 7nm from GloFo as well as TSMC for their cpu and GPU for mid-late 2018 and 2019 as GloFo realized they CANNOT supply all the wafers AMD needs so supposedly they actually worked with TSMC in this regard to be able to keep the designs AMD will use "on par" whether they use TSMC 7nm or GloFo 7nm.
likely the demand will be extreme as hell so GloFo basically had no choice but to give AMD the "pass" to source their wafers as well as others who can also produce them (rearranged the WSA again)
I have been using a TC-SDD06 mini Pc from Thin Computing for gaming and movies, its very easy to move and carry, its fanless so no tension, i did not face any problem yet. Here is the link. http://www.thincomputing.in/best-mini-micro-pc-win...
Good for AMD that they have a 7 nm Vega shipping for sampling - bad for us that it is and will be utterly out-of-reach for regular users. Yes, 32 Gb HBM right there is great, but I would be amazed if that tech can be had for under $ 3000. What is potentially good news is that as they move their high-end stuff to 7 nm, the prices of their 14 nm parts might finally come back down to Earth.
Unrelated, as a question to Anton and Ryan: With this ever-increasing density in transistors, any word on thermals and cooling solutions? I know that (assuming same technology) thinner means lower voltage, so less heat per transistor, but, as they get packed closer and closer together, won't it get quite toasty? Any word on novel approaches to deal with heat removal if the total area of the chip is getting really small for the transistor count?
The topic is very interesting, since this industry is developing very quickly, I also recommend you a useful resource https://www.ligaportal.at/international/ligen-mix/... where you can familiarize yourself with useful material about the differences between sports and esports betting and online casinos, which are often confused by beginners or unknowing people, and this is all simple and exciting, read and know more.

Bad 1080ti are just bad.

do you mean that a 1080ti saturates a 15.76GB/s link. that cannot be trueDragonstongue - Wednesday, June 6, 2018 - link

AMD and Nvidia are both members of OpenCAPI. So why wouldn't they use CAPI? That's Coherent Accelerator Processor Interface.levizx - Sunday, August 26, 2018 - link
Because OpenCAPI has limited usage scenario, eg, it can't be used to replace Memory Fabric, and even POWER9 doesn't use it to talk to each other.It's basically a special implementation of PCI-E.

Any word about fp64/fp32 ratio, full or still the same as vega10?If it's full that die is quite small to pack any extra CUs over vega10(Or even pack as much CUs as vega10).
psychobriggsy - Wednesday, June 6, 2018 - link
Should be half-rate double precision.I.e., if this has 16 TFLOPS FP32, it should have 8 TFLOPS FP64 (assuming no downclocking in DP mode).
