Lol, a lot of people fall into this. Just because you have money to throw away doesn't mean you won't save a penny wherever humanly possible.

Have you not seen the many many ways company's/those with wealth cheat the system to save a nickel?

Ohh yah, I wouldn't fault him for it honestly(though apparently he doesn't do it). I just thought it was kind of odd.

At this point, if you're pirating TV shows/Movies when it's so easy to watch them on Hulu/Netflix/etc. then really, you never were going to accept the traditional way media is disseminated.
Piracy paved the way for realizing that media needed to be easier to obtain in order for people to purchase it again.

When I got cable and torrenting became possible,
I had 2 options.

1. Download a movie in 2-3 minutes in full DVD quality (To my eyes anyway). I'm talking exactly 2-3 minutes.
Or,
2. Drive 15 minutes to Blockbuster, hope they had the movie I wanted, then drive 15 minutes back home.

All this did was pave the way to now have this media available on sources where it's quickly obtainable. But I mean, you're going to have people who cling to that old way, legal or not.

I'm sure in places where legal marijuana and illegal marijuana are available, people still purchase illegal marijuana, or grow it illegally just because that's how they have done it and will always do it, no matter what.

A little off topic though.

270TB Storage server though? Omg....
My little 37TB server.... It's so full and I doubt I even have the same quality rips as you. Jesus.... that's massive, how much is on there?

My Kodi Library Stats are 1700 Movies ~23,000 Episodes of TV. I can't even imagine how much that could be.....

Personally I dont see AM4 ZEN directly competing against Intel HEDT platform. I believe what AMD is trying to do is cover the space between Intel mainstream CPUs (Socket 1151) and HEDT CPUs (Socket 2011-V3).

People that want the best APU (iGPU perf) at the best perf/$ will go for a up to Quad Core ZEN AM4 APU.
Those that want more cores/Threads than what Intel S Series (Socket 1151 and future) will offer, will opt for the iGPU-less ZEN up to 8x Cores 16x Threads.

edit: Im only talking about Desktop Socket AM4.

But aren't those people that need more cores/threads the crowd targeted by intel's HEDT platform anyway? I can see it myself, 6700k is not enough for what I am planning to do, so it will either be broadwell-E or Zen.

Intel current HEDT platform (socket 2011-V3) is very expensive and all of the CPUs are at 140W TDP with Quad Memory Channel.

AM4 platform will be much cheaper due to dual memory and 95W TDP ZEN CPUs and APUs.

It will also be just as limited with dual channel. This should tell you a lot about its actual performance.

And I see AMD is essentially going to be the pro bono company again. Meaning Zen wont have any impact on their negative income.

You just marketed Zen CPU and APU as the same failures the current CPU and APUs are.

You might be right, if AMD wants to add cores or iGPU performance w/o adding their already researched L4 HBM cache to mitigate the 2 mem channel bandwidth bottleneck.

Vishera doesn't have a memory bandwidth problem. Latency yes, but bandwidth, no. A direct successor to Vishera should not really need a quad channel arrangement, especially not with DDR4 bandwidth on tap. One expects that Raven Ridge will have some HBM2 going for it.

Dual channel for eight Zen cores is not bad considering Broadwell will have up to 24 cores with just quad channel.

Also I don't remember seeing complaints about dual channel in the ASRock X99E-ITX reviews I read.

HBM2 would be a lot of bandwidth for a die targeted primarily as laptop APU. (especially when dual channel DDR4 3200 is 51.2 GB/s).

In fact, I'm thinking many of the upcoming dGPUs will not have HBM either.

The server APU will certainly get HBM2 though.

So according to you basically in terms of raw performance it's a very long shot, and in terms of efficiency they do have a shot because of the trade offs Intel made in terms of FP performance. Still doesn't put AMD in a good place on the server market, does it?

From what you are saying here they will not be able to get much, if anything on servers but at least will move to being badly beaten on desktop, an improvement from the utterly ruinous situation they are now.

Really, Zen as a product family is looking more and more like Bulldozer for me. Server optimized IP being sold on the consumer market, but at least this time they are not going against fundamental markets trends (efficiency), meaning that it won't be such an unmitigated failure.
My view: The FP performance for most legacy codes should be OK. HPC on CPU cores will be behind Intel. Server code does a lot of integer and memory stuff. For integer -> 4 ALUs, for memory -> improved cache subsystem and SMT.

And in both cases you seem to forget about power. Let's assume, AMD only achieves HSW integer and IB FP performance per clock. If thanks to a smaller core and lower static power they might manage to do that for example at 3/5 (FP) to 4/5 (int) the power of a SB core doing the same tasks. That means with lots of server threads, they could stay at higher clocks at the same TDP budgets.

It does tend to knock off around 5% from general performance, possibly a little more depending on the situation and exact CPU being used. Not too big of a sacrifice to be made for the sake of a Mini-ITX motherboard, but it does show that the extra two memory channels aren't just there for decoration (or for the sake of those who need the extra capacity).

That being the case, I have a feeling that any 8C/16T Zen chips are going to be in roughly the same situation that Thuban was relative to Gulftown. Thuban's single-thread throughput wasn't that far behind Gulftown's, but the latter's additional memory channel and Hyper-Threading meant it just creamed Thuban in anything multi-threaded.

1) Do you think these assumptions are reasonable?

2) How do these numbers stack up against 14nm Broadwell?

You might also want to have a look at your signature.
I remember shortly before P4 launched, Paul Demone called K7 a tractor.
You see people sometimes makes mistakes. The people that say something unlike all your post where you add nothing.

It's Paul Demone's fault that AMD decided to name one of their processors after an International Harvester product? An informed author, such as Paul Demone, would be remiss to write an article about an upcoming CPU named after a tractor company's product, and not mention it.

Very expensive? Yes the top of the line is, but 5820k is 380ish right now. Are you saying 8 core Zen is going to be "much cheaper" than that? (I am expecting 8 core Zen to compete with 6 core BW-E, especially at 95W TDP.) And with the rumored 10 core BW-E, we might even see the 8 core at 5-6 hundred dollars.

That people who are cluless use cluless arguments as well, i mean, who needs Intel s denomination of a process to know if it s good or not when the voltage of the CPU provide all the necessary info..?.

It s telling about the intellectual poorness of some "commentators" that should better keep mum rather than displaying even more of their usual incompetence about processes...

Whatever you say, Abwx.

I should point out that you tried to sell the idea that 14nm was a regression from 22nm when this was clearly false, and you have been trying to sell the notion that Intel's products are actually worse than AMD's, when this is also clearly false.

Laws of physics are what they are, whatever the saying of the fanboizs, a transistor A that need 1.1x higher voltage than a transistor B to switch at a same frequency will have inherently 1.21x higher power comsumption, and that s the ratio between GF s and Intel s process used for BDW.

It could be even worse than that as SKL seems to necessitate more voltage than BDW although this could be due to high dispersion of the process, but whatever AMD will not be handicapped by a less efficient process, to the contrary, up to 3GHz+ they could have the upper hand independently of the uarch efficency.

I can't stand going to a web-site to have to watch my videos. Nor can I tolerate needing to run custom software because I run such a wide blend of operating systems and don't like being tied down.

I buy all of my shows/movies, but ripping them and encoding them often takes longer than downloading them, so I sometimes end up downloading them anyway (mostly for TV seasons). Maybe Zen will help with that

So you have been able to verify this with two identical processor designs, but with one manufactured by GloFo and one by Intel?

It could be even worse than that as SKL seems to necessitate more voltage than BDW although this could be due to high dispersion of the process, but whatever AMD will not be handicapped by a less efficient process, to the contrary, up to 3GHz+ they could have the upper hand independently of the uarch efficency.

Let's revisit this discussion when GloFo is actually pumping out chips for AMD and we have actual silicon to compare. I guess it's only a year to go...assuming AMD meets its schedule.

And here you are lying because i stated that the perf/Watt improvement was about 13.5% but that the transistors performance was hugely degraded and compensated by the layout and input capacitances at the rate of 0.6 as published by Intel, 0.60/0.835 = 0.71, that s the loss in conductance of the transistors from 22nm to 14nm..

Next time keep your facts straight as you are caught in blatantly deffamatory claims wich are obvious lies, check my post history about the numbers above if you want, you would be hard pressed to sustain your dishonnests statements, a practice that indeed do not surprise me at all coming from you...
