Because it is not 6900K competitor, but its Socket 1151 competitor.

Its both, 8C ZEN will compete against HEDT Intel SKUs (i believe up to $1K), 4C and 6C ZEN SKUs will compete in mainstream against Socket 1151

You keep saying that when AMD directly compared the 8c/16t to a 6900k.

Exactly. If AMD was going to price the 8c part to compete with the 6700k/7700k, it would have used those parts when comparing performance. The fact that AMD used the 6900K is a giant neon sign that AMD will price accordingly.

Why couldn't Sr7 be desktop and some other variant be HEDT?

Sr7 against 7700 series and top end RyZen against HEDT chips.

14nm LPP has 20% better transconductance than Intel s 14nm, so at equal input capacitance this mechanicaly get you 17% lower gate delay (at same VDD), or FO4 if you prefer.

Dunno for said input capacitance but there s no reason that it would be higher for GF s 14nm.

I have no data to say that any of the feature of 14nm GF is better than INTEL's. The only thing that know is that INTEL's is denser and many says that is better. This is not the first time that you said that. I know that 14nm FF is better than 28nm BULK, but where can be seen what you said? Were transconductance values for both GF and INTEL published? I would like a link to read...

Despite the product isn't launched yet and the performance still isn't officially confirmed, yet I have to say that I'm simply stunned. Not only by Ryzen, but the sudden change AMD has gone through. In reality of course the change hasn't happened over night however it still feels like AMD has suddenly been waken from a bad spell, which has lasted for almost seven years. Most of you are familiar with the things I've very openly criticized during the past couple years, in regards of the products themselves and the marketing / general policies AMD has practiced and executed. I'm fully aware that many of the things I said were harsh, but that was mostly intentional and I don't regret any of it as I never had to lie about any of it. In those cases where the harsh comments weren't intentional, they became more harsh than intended out of plain frustration.

If a year ago I would have been asked to bet my life either on AMD or against AMD, I wouldn't have had any other choice but to bet against them.

- Hitting competitive frequencies on a design manufactured on a low power manufacturing process, targeted for handheld devices - (allegedly)
- Meeting, let alone exceeding the advertized marketing figures (in this case the 40% IPC improvement over XV). Let alone by a figure, which apparently can be nearly 40% higher than originally quoted (up to 55% absolute over XV) - (allegedly)
- Be able to even remotely keep up with the original promises, let alone vastly exceeding them.

For the record, I was wrong about Zen.
For the Fmax part due having a prejudice against low power processes in general and against GlobalFoundries in particular, and for the IPC part because I couldn't even dream that AMD could meet, let alone exceed their advertized IPC figures.

If I wore a hat, I would tip it to AMD right now.

hmm So you were at CES? did they show you ?

Well if you see above i said im expecting 8C ZEN SKUs to start at close to $400, so a SR7 8C SKU could be positioned at the very high-end mainstream spot to compete against KLB 4C 8T priced at $330-350.

Hmm if it beats 6900K, why would you even think about comparing it to Socket 1151 SKUs? AMD is not a charity, they will price it above i7 s1151 mainstream range for sure. For sure they will undercut every single intel SKUs in similar performance bracket, they want both higher margins and higher market share.
I am sure they are going for the same segments and customers. The sr3 5 7 screams it out loud. Now they will probably go for the premium brand development meaning selling them 50-100 more expensive than equivalent i3 5 7. But they need to adress the meat of the market and there is like sold no 800 usd cpu. You can have black skull gamerz oc 150w edition selling for that but its not what they intend to do. I dont actually know if pricing is that dependant on the last plus minus 5% perf. Its all about segments and intel have made the groundwork here. Pretty smart imo to lean on that brand and core naming as amd have little marketing muscle and zero selling muscle compared to chipzilla.

Im looking at the X300
This guy gets it.

Tho I might correct, from what I gather those itx motherboards wont even feature a proper pch? Considering Zeppelin is a true SoC?

Anyways, Im waiting for itx mobod and prices to finally decide if the time has come for my 4790k

SO can some of you smart people tell me that if these clocks are true for the 8c/16t chip, then I can likely pick up (let's say ~summerish?) a 6c/12t Ryzen chip with something like 3.8-4ghz base clocks minimum, a little under 90w TDP, for like, $300 bucks or less?

OK, I know that no one knows anything about pricing, but if the 6C are the "mainstream/ low enthusiast" Ryzen chips, I imagine they are going to be towards the top end of mainstream pricing, right? Let's assume they price the highest-base 8c/16t Ryzen chips at $500-600...

The AM4 platform might be the biggest thing holding Ryzen back from fully competing with high end X299 (or even X99/BDW-E) sales. Depending on your use case, 16 PCIe lanes + the chipset could be limiting for a small subset of users. The early signals on the chip itself look great though. I can't imagine that I would be able to justify it, but it sure would be tempting if things actually develop as people here seem to expect.

My bet would be that they're gonna go after the mainstream i7s with the 6c, maybe undercut them a bit. At least that would make the most sense to me.

Well here my view :
AMD Ryzen 95W TDP with unknown power consumption
Intel 140W power consumption with unknown TDP

No ? I think at 3.6 ghz , both does have same power consumption.

This looks to be an absolute overwhelming result with those frequencies ...chapeau!

And for those clock AMD can even charge 600-800$ for the top end SKU...fine with me!

All that's missing is the silicon in stores near us......please, please...let it be really soon I need a new rig...

Agreed, I think their aim is to push 6C+ as the real mainstream and show everyone that they can, again, provide far more value at a lower price than Intel. Man, it's been a long time. I hope it pans out that way.

I would also be looking at the X300. I've been interested in a SFF PC for some time, as I've never built one and only ever went easy and boring with midtower cookie-cutter stuff. IF Vega further pans out with their power target based on Ryan's article...I'd be very happy to put together a ~450W 6c Ryzen + Vega SFF system.

oh you're right I'm a dummy--confusing TDP with W again.

Its very telling that Intel will release KLB-X (4C 8T) for the HEDT x2066 socket. They will try to lure people to HEDT platform by making it available with a lower budget 4C 8T SKU and give you a up to 10C 20T upgrade path . Much like how AMD will do in the mainstream with ZEN.
Also Intel will give more features on the HEDT 2066 socket platform than AMD does in AM4 and many people will choose lower CPU perf with higher-end platform vs ZEN higher CPU perf (higher core count ) at lower platform cost/features.

You have to remember that Intel's max power consumption have to be measured on AVX/AVX2 workloads as they have 256 bit FP units. Most common workloads like gaming or productivity rarely (if at all) use the 256 bit FP units. AMD's Zen has only 128 bit and not 256 bit FP units. Intel will have higher performance in AVX/AVX2 workloads wrt Zen but at higher power cost. If we measure power consumption in an AVX/AVX2 workloads then we are likely to see Intel get closer to rated TDP.

Except that it doesn't suck. Those boards which are fitted with an A320 chipsets are also going to have extremely poor VRMs. I'd be amased if an A320 board is able to support 8c ryzen without throttling because of high VRM temps. Disabling overclocking on the low end boards is going to save someones house from burning down.

Except, manufacturers could make no frills boards with good vrms and only the necessary ports. This way, a320 would come in handy since it would drive the price down. Or even buying a cheap board no so good vrms for overclocking lower power (50W ?) QUAD core parts. It's stupid to lock down such features via chipset.

Stupid and childish chipset naming, having to have a number that's one bigger than Intel.
