Thanks mate, interesting.:)

AMD are late to the game on this one. That PDF is being very economical with the truth.

Late to the game yes, Nvidia has a great advantage, but it's still years away and gfx sub gamers probably won't use this tech anyway, I think it would take off in mobile devices???

Economical with the truth, they both are, but Samsung showed that embarrassments can happen when being very economical with the truth, and well, Roy is King for AMD:D

It's an interesting technology, and something that I have been working with recently. But AMD are late to the game on this one. That PDF is being very economical with the truth.
https://blogs.vmware.com/euc/2015/03/nvidia-grid-vgpu-vmware-horizon.html

Which bit is economical, it says max 8 users per gpu and that Nvidia Grid is software virtualisation only, both of these things are confirmed in the Nvidia blog you linked. K1 is a quad gpu card, K2 is a dual gpu card. AMDs solution is in hardware and can provide for many more users per card.

Late to the game when you are providing a hardware solution versus a software solution, nope that would be AMD massively ahead of the game... again.

Every link, every headline even the video name says first hardware based solution... then Nvidia fan boy comes in claiming Nvidia did it first, AMD is lying and provides a link proving AMD are telling the truth.

It's actually becoming a little silly that you keep linking to proof that you are wrong.

hell if we really want to be accurate Nvidia is being economical with the truth. Max 16 users per GPU it says there except here

http://www.nvidia.co.uk/content/cloud-computing/pdf/nvidia-grid-datasheet-k1-k2.pdf

it clearly says a K1 has 4 gpus and a K2 has 2 gpus. Much more accurate is the vmware blog which accurately says max users per board not per GPU as Nvidia is claiming.

Well said.
 
Good to see AMD not letting Nvidia get ahead and has promise. A couple of threads have mentioned this but not much interest however, with AMD now involved, I am sure it will be fantastic news.
 
The of the biggest issue that AMD always have had is that they keep bringing hardware and better support for features that are ahead of its time (which is not a bad thing for the users as their hardware can be used for longer before the next upgrade), and and they don't become immediate benefit when their product is launch (more cores on their CPU, more vram, better support for dx12 etc.), so they don't really do much in turning into profit or revenue for the company. Nvidia is making far more profitable due to their approach of ensuring their product won't age well and won't last longer than necessary, so they get far more repeat custom.

IMO if AMD wants to gain back the marketshare, they'd need to stop bringing users things ahead of its time (which would be a bit sad for the users, as for example the older 290/290x would probably still handling dx12 games fine, while the newer 970 wouldn't tank in performance at faster rate), and take the same approach as NVidia focus more on performance at the launch and forget about benefit for the future.

AMD are crowing about something which is late to the game and completely unproven. Right now all we have is a puff PR piece from AMD with a bunch of claims and nothing to back it up. In comparison the NV solution is a tested and proven solution available in production and hardened enough to by used by some very big clients. No amount of hand waving by somebody who literally cannot accept that AMD might be behind in anything (see also the increasingly desperate and reaching claims made each time AMD announce continued financial losses) will change that. AMDs solution is bringing nothing new in terms of function or form, they are playing semantics.

I guess you are going to go off on a bunch of increasingly tedious and incorrect rants yet again. Just like you did the other day when you raged about me daring to suggest NV had something similar to HSA functionality cooking away, well just take a read of this, seems highly respected technology sites agree with me and not the angry AMD troll. http://arstechnica.co.uk/gadgets/20...-and-radeon-veteran-phil-rogers-joins-nvidia/ well fancy that. The Ars Technical hardware editor is saying exactly what I was. Where as the guy who wrote for some unnamed failed hardware blog spent ages writing increasingly mad walls of text raged otherwise. Do you want to play this game again? Really? As each time you end up wrong and either disappear from the thread in shame or attemp to bury the facts beneith a mountain of words that actually surprisingly little.


Whelp. That was far more than I wanted to say, but I'm really tired and annoyed that individuals like that are constantly allowed to derail threads.
 
Amd have some good things going but they cannot seem to gain any traction

That's because they're turning into a jack of all and master of none, They have limited resources and funds so they should reduce the directions they're heading in and complete projects before adding more.
 
Serious question. I have deployed the NV solution, what real world advantages does AMDs solution bring? Current information available is lacking in any real substance.

So you post in a thread, are entirely wrong again, I asked you specifically by the way which parts of AMDs information was inaccurate which you claimed and I'm shocked to find you haven't responded.

If I leave a thread it's because I've proven beyond a doubt you were wrong. You posted nothing factual or useful in the HSA thread and I posted information from AMD and Nvidia that agreed with what I was saying. In fact 99% of people in the thread said you were wrong, when everyone knows you're wrong and your argument as to why you're right is basically just saying "i'm right because I say I'm right", people get bored and leave, that doesn't make you right.

You derail EVERY thread, you derailed the HSA thread by coming in and pointing out how Nvidia were doing the same things, you derailed this thread, you came in and straight away said AMD were lying. Called on it, with proof from Nvidia, AMD and other sources, you don't refute anything, you can't prove anything, you post no information to back you up. Nothing at all in that article 'agrees' with you or your view point.

If anything it says

which boasts its NVLink CPU and GPU interconnect, allowing for heterogeneous computing setups that are similar to what AMD's been pushing out for years.

which is directly saying Nvidia needs those things to match things AMD has been doing for years, and HSA is well beyond anything AMD has done previously. If you want to be literal arstechnica are saying Nvlink helps Nvidia achieve with the NEXT generation what AMD have been pushing out for multiple generations already, so it's saying Nvidia are miles behind and Nvidia brought him in to attempt to help to catch up. More to the point, it's inaccurate. Nothing about NVlink allows on die scale communication, level of latency or ability to send small bits of code for gpu acceleration. Nothing about NVLink enables anything like AMD has been pushing for years. Nvlink is there to improve access to gpus to system memory and decrease the bottleneck in multi gpu systems, it's inherently designed for systems where 99.999% of the load is on the gpu, it's also exclusive to SOME IBM chips and SOME IBM motherboards and has no chance at integration in the desktop market. Sure Nvidia might get some stupid companies to put some NVlink chip on the motherboard so you get 16x pci-e to the chip then the chip connects to 2-4 gpu slots with increased bandwidth between the slots, which isn't entirely pointless but is already done with a pci-e bridge chip. Minimal gains and absolutely no need for higher power links providing a level of bandwidth that isn't required.

You use irrelevant posts to attempt to prove your side of the argument when your links directly dispute what you are claiming.

YOu go into every AMD thread and say "this is tech Nvidia have, this is AMD way behind or AMD are lying here", every single one.

Once again, you accused AMD of lying with their information and you claimed Nvidia had 'this' for years, this thread is about HARDWARE virtualisation, not software. You are the one making bold claims about Nvidia's capabilities.

No, I'm right because I am right, the weight of evidence proves that. If you disagree then that's your issue (of many). I read up and put together the information available and came to a conclusion based on that. And hey guess what, the hardware editor of a highly respected tech site said exactly the same as I did a day or so later. Obviously this makes the failed tech blogger angry and he has to write big long walls of text in the hope that the tsunami of words will convince people through sheer volume that his angry assertions are correct.

So come on then, tell me, why is this better than the tried and proven solution from Nvidia. Why is AMD's approach better, what benefits does it give me over what I have already deployed? How does their claimed HARDWARE approach differ? Try to educate me instead of ranting about how AMD are so super duper brilliant and NV are nasty evil people for daring to be far ahead in bringing a solution to market. You keep going on about how this is a hardware solution, but I don't think you know how this technology works.

AMD are late to the game and are not bringing anything new into play. If people want to make threads crowing about some supposed new technology, don't cry if somebody points out they are late to the game. Nvidia have some big wins from huge companies already http://www.nvidia.com/object/enterprise-virtualization-success-stories.html and has been proven a hardened enough solution for Microsoft to deploy it into their Azure infrastructure (where they certainly wouldn't if it exposed any security weaknesses). http://vmblog.com/archive/2015/09/29/nvidia-gpus-to-accelerate-microsoft-azure.aspx

So one last time, why does AMD's solution warrant being touted by yourself as so superior to one that has been proven in productions environments as stable and secure enough for the likes of big manufacturing, education and finance?

Firstly I didn't say Nvidia were evil, in either of the recent threads, I said YOU were wrong, it's got nothing to do with Nvidia, you are wrong that is all. Once again you have no argument except you're right because you're right and anyone disagreeing with you is not because you're wrong, but because they hate Nvidia, even when extremely pro Nvidia guys are calling you out for being completely wrong. Every time someone posts a fact or points something out to you, you personally attack them while ignoring any and all information given to you. Despite that fact that you jump into every thread every day to spew hate at AMD, anyone calling you on it gets accused of derailing. YOu bring nothing to this forum, no sensible discussion, no useful information. Just links mostly to information proving you wrong.

Hardware virtualisation, if you honestly don't know why it's better go and read up on the difference between software and hardware virtualisation on the CPU, most of the differences will be the same with GPU.

You can't be late to the game if you are the first to do something, you were wrong about everything you said in the first post and you refuse to admit it, your own links absolutely prove you are wrong. The claim AMD made was first hardware virtualisation, you accused AMD of lying and you specifically said Nvidia could do the same, they can't.

There is no weight of evidence that proves that and again, the hardware editor of a marginally respected website did not in any way agree with you. He specifically stated that NVlink would bring Nvidia features AMD has had for years, they haven't had HSA for years.

Not one place in that link suggests NVlink performs the same functions as HSA, not one link you've provided has suggested the same. Your repeated posts on HSA and your claims about what it's for prove as much, you at no stage even knew what the main goals of HSA were or what the main features were. You still won't admit that nvlink is just an interconnect, when Nvidia compare it solely to pci-e. Nvidia has no where anywhere compared nvlink or any of their technology to HSA, you are the only one doing this because you don't know what you're talking about.

Everyone in that thread pointed out that literally everything you were saying was incorrect.

AS we have here, you don't fundamentally know the advantages of hardware virtualisation nor can you read the link because AMD describes some of the advantages. A software layer has a large overhead and provides less scalable performance, hardware solutions are universally higher performance, more reliable, higher security, more easily managed, less prone to bugs. Anyone with any even passing interest in virtualisation, computing, programming would know that.

When cpus brought hardware virtualisation is was huge for a very good reason.

Is there anything that AMD are not the worlds first on ? Multiuser GPU, Low Level API, VR, homogenius cpu, freesync..... you would think they are a huge rich corporation, when in reality.......
 
M8, I never said NVlink itself brought the same functionality, I said along with other technologies NV had, it would enable them to bring similar functionality to market. For what ever reasons you just could not accept that and we made the thread crash and burn.

Now without, repeating verbatim from AMD's press office, tell me why their solution is so superior to one that is mature enough to be deployed into an infrastructure as huge and vast as Azure.

I'll give you one little tip, in Horizon the virtualisation is being handled by the ESXi hypervisor, so you are deluding yourself if you think AMD's solution is going to scale better or be more secure. So please, educate me, why is it better, and no regurgitating of AMD's hand waving press release, in your own words for once.

Microsoft for example have this to say:
"As a leader in advanced visualization, NVIDIA GPUs were a clear choice for our new N-Series compute family," said Jason Zander, corporate vice president at Microsoft Azure. "NVIDIA and Microsoft have a long history of enabling industry-wide innovation and we look forward to working with them to bring this revolutionary cloud experience to our customers."
I guess the Azure VP is wrong as well, perhaps you should send him an angry email stating why he should switch. In fact have AMD got any confirmed design wins, or anything even in the pipeline?

AMD are late to the game, and are playing semantics in an effort to try and promote their solution.

Am I correct in thinking that this sort of tech could be used in cloud gaming? If so then hardware based virtualization would be quite a bit faster than software implementations.
