What it says is that AMD plans to release it in Q4 2016. But it also says "no firm release date has been set". It does *not* say a release date has been set for 2016.

.

From the article :

AMD’s planning to debut Zen based desktop FX CPUs by Q4 2016, just in time for the holiday season.
Perhaps that you need the exact day as well, unless it s rather a pair of glasses...

I HOPE AMD can reach console level performance in the APU. That's what the APU needs to be successful. If they can deliver a console level of performance consistently, the APU will do GREAT with back to school gamers, and really just make it a far more versatile chip. If AMD has enough GPU performance in the APU to catch the consoles, then the APU becomes interesting because sure, it may lack CPU performance, but at least you can game on it every now and then for real. That was my FAVORITE part of my laptop in highschool when I was 18 was firing up GTA San Andreas and that laptop wasn't remotely meant for gaming. An APU laptop like that going into college that could play all the latest games and be used for school and isn't significantly more expensive than a normal laptop? That's perfect, and if AMD can do a promotion with Steam on those laptops to offer free games, a discount, a bundle, something, that would be a perfect opportunity for Valve to convert some people who may have been college console gamers into PC gamers.

There's been potential on the APU front for AMD the GPU portion has just been too weak really to truly recommend except maybe on select SKUs/titles.

I could see xbone levels, yes. PS4 seems like a lot bigger stretch, at least at a reasonable die size, cost, and power budget. It all depends on availability and cost of HBM like you said. The cpu should at least be a lot stronger than the consoles, so it might be more competitive in cpu demanding titles.

But by the same token, we will have 14/16 nm dgpus by then, so that will raise the bar considerably for APUs compared to discrete.

I really don't think it matters. You're splitting hairs between the PS4 and XboxOne. 900p vs 1080p, ya some titles drop down from 60 FPS to 30 FPS, but we know that it's not because the Xbox One can't run higher than 30 FPS, it's because it can't run 60 FPS so they need to lock it somewhere and choose 30 FPS.

Otherwise, if an APU can do Xbox One level of performance, it's going to be more than enough for someone to be happy. APUs just have to deliver XboxOne or better performance across MOST skus to be truly attractive. Otherwise, I'd rather just have intel's performance. Now, if that APU can be utilized in conjunction with a dgpu during gaming (DX12?) then that will be interesting.

The APU is interesting, it's just been way too weak to be a true contender before but maybe a nodeshrink gives AMD enough to make an APU capable of delivering the weak XboxOne/PS4 level performance it needs to be successful.

Well considering what is inside the consoles its really rather safe to say that AMD can already produce an APU with the same performance

Had they been in a much better position in terms of R&D budget etc, we'd probably have seen something already. Maybe using the eDram stuff like the XB1/iris pro.

Really, by 2017 with HBM and the very much smaller process, they should be able to get a good way ahead of the consoles if they push the graphics.

Most likely the number of SP. But 768 or even 1024 is not much of a stretch given that they are shipping with 512 right now. You'd obviously need something to increase the bandwidth beyond just dual channel DDR4 2400. HBM would be the obvious answer, but that's going to be way too expensive for OEMs on a chip that's already going to be really expensive to make. That doesn't mean AMD won't try though.

Right now AMD has 512sp @ 25.6 GB/s bandwidth (dual channel DDR3 1600).

But if AMD predicts dual channel DDR4 3200 becomes mainstream they will have 51.2 GB/s bandwidth to use. I think 768sp and maybe even 1024sp (low clocked) could fit that.

If they go 1024sp the die will be large and it will be an expensive product.

But how will that compete against Intel's best 14nm or 10nm?

Maybe it is better for AMD to get a better hold on the mainstream by offering more CPU than Intel. (ie, 4C/8T small iGPU die vs. Intel's 2C/4T small (GT2) and 2C/4T medium (GT3) iGPU)

Let Intel be the iGPU company and AMD be the more CPU oriented company in the mainstream. I mean how much iGPU does the average person really need?

In other words, make AMD "higher end" by offering us more CPU (rather than more iGPU). Then, if necessary, AMD can augment with dGPU.

This is the problem with the ADF. They would rather beleive a clickbait website rather than AMD themselves.

You need the glasses to read that AMD has said Zen is a 2017 product.

I still think it's a 2016 product, a paper launch though.

It will probably come down to the old argument about shipping to OEM's vs availability.

The test should be something like when can a regular joe buy it from Newegg.

And lets not forget this is the same publication that said Skylake was going to be a Conroe like jump in performance.

And the endless amount of other rubbish cases. They just copy/paste randomly from forums and make up as they go. Using wccftech as a source means you already lost. Why people ever visit that site is beyond understanding.

When your posts don't line up with what the Internet STRONGMAN Juanrga has been saying, who are we to believe?

CHADBOGA, what is this "Internet STRONGMAN" reference? I see it used to describe the "juanrga" poster on S|A and RWT, but I don't get it. Would appreciate an explanation so that I get the joke(s)

Plan A;
Summit Ridge FX14 -> 8C/16T "Zen"
Raven Rdige FX14 -> 4C/8T "Zen" + 1 Shader Engine "GCN4" [16 CUs]

Plan B;
Viper Gecko 22FDX -> 20C/20T "Tunnelborer"
Basilisk Gecko 22FDX -> 10C/10T "Tunnelborer" + 1 Shader Engine "GCN4" [16 CUs]

Who outside of intel uses/used a 22nm node?

PS4 has 50% more shaders than xbone. I would not call that "splitting hairs", especially when you are trying to cram it into a package with a cpu.

It is a reference that I coined for him initially on RWT, due to his antics primarily on S|A and to a lesser extent on RWT.

Due to my warped sense of humour and his style of posting, he just reminded me of a South American "Strongman" dictator from the 20th Century and someone with utter blind faith in their own righteousness.

Obviously the description has resonated with a few people familiar with him(even if they understandably didn't exactly get the reference), so they have been using it to refer to him too.

On S|A, Juanrga bested ABWX, just as Juanrga has bested everyone he has ever come up against in debate. LOL

I fear it is only a matter of time before Dresdenboy becomes his next victim.

Oh, there is a method to the madness though. The end of 2016 is when they are badly going to need cash to continue. Imagine using reviews from enthusiasts sites to crow about Zen ("AMD is back!!!") to try to convince Junk Bond dealers to front them more money. The paper launch of course obscures the actual demand compared to what AMD really needs to sell.

Actually, I am expecting a launch much like intel 14nm. Formally launched, but very slowly trickling into retail availability.

But why not use a dGPU? (Example: Apparently Carrizo isn't even offered as 35W laptop yet. Instead OEMs are using 15W Carrizo + 15W dGPU for their notebooks.)

Maybe a volume 4C/8T Zen APU that works well with one 8GB stick of DDR4 3200 RAM and beats Intel 2C/4T GT2 (also using one 8GB DDR4 3200) would open more design wins?

(This assumes one 8GB DDR4 3200 stick ends up cheaper than two 4GB DDR4 3200 sticks).

Ah, gotcha. Thanks, this is something I have been wondering about for a while.

For a laptop, if they could reach something like GT 950/960M performance in a 35 or 45 watt APU and sell it cheaper than intel + discrete, it would be attractive. I even think Intel could probably do it with Cannonlake, but they will restrict it to high end halo products.

But with desktops, I think discrete will remain the better option in most cases, especially with the 14/16nm cards coming out. I also dont expect Zen APUs with HBM until late 2017 at best.

I feel like the CPU itself isn't going to "wow" the masses with raw performance.

I mean yea, it'll come with nicely improved IPC...but if it's really ending up as some 16thread monster at 95W...I can't really see it being super highly clocked.


I'd almost think we'd end up with some 3Ghz 16 Thread and then a 3.5+ 8 Thread CPU.

Of course this is not based on any official info here...just trying to make sense with the tiny amount of information we actually know/have.

I do expect them to support high frequency ram, though. I wouldn't be surprised to officially see them support 3000 Mhz or higher right off the bat. (I feel like Intel has always been rather conservative on the officially supported ram mhz...not sure why, but I feel like some Intel pros can shed some light on this for me)


And then there is the Zen APUs later down the line with a far higher tdp. If those insanely high TDPs that we heard about hold true...the remaining juice would almost be enough to power something like an R9 Nano...but of course that is just insanely wishful thinking.

So that + DDR4 @ 3000 Mhz+++ might be a very viable product if the pricing is acceptable. Especially since DX12 would have established itself a bit more by then and APUs/iGPUs will see some more use.
I won't dream about those APUs have on-die HBM for now...just because that would sound too good to be true.


Personally I'd be interested in a smaller 8-thread Zen CPU or APU with higher clocks since personally I wouldn't see 16-thread as anything necessary for since I mainly game on systems. But then again...it will only be interesting if the performance-per-dollar ratio is acceptable. Which is harder and harder to do since Intels' performance is just so far ahead that that alone can bring a good performance-per-dollar.

But somehow I can't shake off the feeling that pure CPUs are somewhat of a mistake in the consumer PC area in a time where APIs are trying hard to actually make them useful.

I'm not so sure. OEMs at this point have pretty much ignored Intel's efforts on Iris so far. A large reason for this is because they very much favor nVidia GPUs on machines marketed for gaming. It's gonna be tough for even Intel to fight that.

From what I've read in an overclocking guide, and my personal experience with my 3000mhz DDR4 installation this last week, it can be very difficult to get working and is very temperamental to get it to pass the memory test. I imagine that it may be that Intel was conservative on official acceptance of it due to it being so temperamental. (I had to try several different ordering of identical sticks until it finally would pass its test and work at 3000mhz).
