Zen 2 won't have anywhere near 29% more IPC, I'd have to be smoking some funny stuff to believe that again.

Most of you guys are writing as if you're buying EPYC. I bet 99% of you are NOT. The speculation here is all what has been presented for EPYC, especially the way the package is. There's no confirmation on what Ryzen will be exactly and how it'll be packaged. Lets just be honest here about what you are all actually buying and/or willing to spend money on.

I doubt many of us will buy EPYC 2, but that's why we're talking about the core itself - it's independent of what SKU we're talking about.
Ryzen 3000 could come with nothing smaller than a six core CPU (I hope AMD does this - Intel could barely adapt last time when quad core became the new low end mainstream CPU).
AMD gets 800~900 usable chiplets per 7nm wafer. Assuming a $12k wafer cost (which is close) and a relatively high defect rate of 0.3/cm^2, that's just $14 per chiplet. Two of those and a $10 IO die and you have a quite similar bill of material as Ryzen originally did on launch... except now AMD has 16 cores on the mainstream desktop and can happily ask $600 for it. And I'd pay it.
You're not taking into account the fact 7 nm process isn't mature yet, dude. Also, isn't the wafer size supposed to be 300 mm?
According to this:
![]()
I chose a defect density of 0.4 because it's a new process, and with these parameters, AMD would get 612 good dies. Note the die dimensions are rounded down (from 73 mm²) to make the calculations a tad bit easier.
Here's the link for the Die Per Wafer Calculator: https://caly-technologies.com/die-yield-calculator/
We don't know the defect rate so any speculation wrt same is pointless, what's more relevant though is the price these chips command in the server space or high end retail. The price of dies is rather low, so that's not much of a problem anyway.
The headline number, for me, is the usable dies ~ which directly translates into lower/higher cost (per die) depending on defect rate. The number of usable dies is really important because it helps AMD keep up with their scheduled timelines, launch dates, demand & commitment especially towards large customers. It is said (by some) that AMD sold every chip they could produce in the Intel OEM bribing era, I can't say how true that is but AMD atm absolutely needs to fulfill the demand for Rome & compete for the growing needs of enterprise sector. Which is to say that the cost of dies is secondary, but again directly related to defect rate, right now while meeting obligations should be the primary goal, especially the Super 7 plus one.Well, a $20 chiplet would dictate that Ryzen can only really afford to have one chiplet without having two designs - one with one chiplet and another with two.
$20 represents ~600 usable dies per wafer. A silicon bill of materials in excess of $50 for Ryzen's core would be a big jump... and a big risk to bring to the mainstream market.
At $12 per chiplet - a price that will decline with time - AMD can toss two chiplets onto every Ryzen CPU, with a BoM pretty close to Ryzen's original costs.

0.4 would be rather bad. 14nm had 0.08 at launch, I seriously doubt 7nm HPC has anything notably higher than 0.3 - and probably closer to 0.2 or even below. I based my numbers on a range from 0.2 to 0.3 (which I probably should have stated in my comment).
6.75x9.45mm = 63.79mm^2 = 731~938 usable dies with a 0.4 defect density and 0.12 scribe h+V lanes.
Move to 0.3 defects/cm^2 and you have 827~938 usable dies.
No Zen was the first high performance chip using GF 14nm, you could count Polaris but that's not exactly apples to apples.Are you referring to the 1st chip on 14 nm or to the 1st Zen chip on 14 nm? IIRC, when Zen was introduced, there were several chips being manufactured @ 14 nm, meaning the process was much more mature then 7 nm, where it is the 2nd chip (1st is Apple's A12 chip).
What is your source of Zen 2 CCX chiplet size? From what i've read, Zen 2 CCX chiplet measurement is roughly 73 mm² while yours is almost 10 mm² smaller.
For reference, i got those measurements from this post @ Anandtech forums.
When i made the pic in my previous reply, i was under the impression the CCX chiplet size was 72 mm² and that the chiplet was a square instead of a rectangle.
According to the die calculator page, those scribe values are invalid: either 0.1 or 0.15 but not 0.12.
Base on the current information, and with a defect density of 0.25, we get this (7.3 is also an invalid number for width so i improvised):

The 8121U has its AVX512 units (as well as pretty much everything else) disabled.So a cheap 8121U has AVX512 and also the $359 7800X 14 nm, so mainstream AVX512 is a reality that could have been widely spread by now.
None of us will be buying EPYC. That's why we're taking what they've said about it and attempting to extrapolate what this means for Ryzen 3000 and TR3. Also, it's interesting to discuss when someone makes some actual innovations in this space, even if we're not in the target market.Most of you guys are writing as if you're buying EPYC.

I'd actually consider the same, even if I'm very happy with my 1600X.If AMD keeps their prices very competitive like they are now, I will be upgrading to Zen 2.

So what gives better yields then? Smaller dies at 7nm or a huge one at 14nm? Yes the I/O die is done in GloFo's 14 nm.
@Aquinus It was confirmed at the NH event that the I/O chip is on 14nm.
My guess is that it could be from GF which keeps GF in the game.
Sure but, it's still on a mainstream platform so I consider it mainstream even if it's the highest end of the MSDT market.TBH I wouldn't call the 9900K "mainstream" due to its heat, price and availability. It's pretty clearly showing the limit of the Core uarch on 14nm, and I suspect that its successor will only show up once 10nm is fixed.
Anandtech does a great job with their Bench tool on their website. It helps with conversations like this one. Here are the Full package load power measurements for the last four Intel generations:This is really not complicated. More cores will draw more power, there's no bending the laws of physics. However, if you lower the base clock, you will draw less current (power does not scale linear with frequency), thus your heat sink will be cooler. When the heat sink starts cooler, it can accommodate higher frequencies for a while, until it heats up.
Again, I see no trickery at work. Just a company finding a way to squeeze more cores on a production node they were planning to leave behind at least two years ago. Both Nvidia and AMD had to do something similar when TSMC failed with their 22nm node and everybody got stuck with 28nm for a couple more years than originally planned.
Well, I don't see it as deceptive, because 95W is all a board manufacturer has to support.

I'm not who you're talking to, but I agree with the conclusion of AT's recent look into this: they should start having two numbers, one "Base TDP" and one "all-core boost TDP". That'd clear up everything quite nicely. Base TDP would indicate minimum performance specs and power delivery requirements, and all-core boost TDP would indicate what your cooler and motherboard need to match to provide the best possible out-of-box experience.Anandtech does a great job with their Bench tool on their website.

There is a major change between the 7th and 8th generations. However, Intel rates them all as 95W. You don't see a problem with this?

I wouldn't mind having two numbers on the box (though as I have written above, it will certainly confuse less informed users), but which numbers would Intel use? Because only the base TDP is mandatory, the other one is left to the motherboard vendor's will.I'm not who you're talking to, but I agree with the conclusion of AT's recent look into this: they should start having two numbers, one "Base TDP" and one "all-core boost TDP".

Which is exactly why you call one "base" (as in "base clocks", minimum in-spec performance) and one something else. This might be a bit confusing, but no more than people buying a chip with a shitty cooler and cheap motherboard, expecting matching performance from a review, yet getting 10-20% less.

Oh, gee, that's so simple to explain. Try saying that to the average buyer, see how it faresWhich is exactly why you call one "base" (as in "base clocks", minimum in-spec performance) and one something else. This might be a bit confusing, but no more than people buying a chip with a shitty cooler and cheap motherboard, expecting matching performance from a review, yet getting 10-20% less. Which happens quite a lot.
By making the second number official (determined by, say, the average all-core-boost power draw of the bottom 10% of chips in a specific SKU under a punishing load) Intel could make implementation uniform across motherboard vendors, with a simple "TDP" BIOS option, ("95W Base" for restricted to stock (with short-term PL2 above this) "Performance" for slightly loosened but reasonable limits, and "Unrestricted" for balls-to-the-wall?). Mainly, the second number would serve as a guideline for buying a cooler and motherboard, and it could lead to motherboard makers labeling their VRM solutions with actual useful numbers instead of "X-phase". Ultimately this could lead to less confusion, as it actually serves to explain something complex to users instead of just trying to hush it up. Intel already allows for adjusting all of this in XTU (although a lot of motherboards ignore XTU power limit settings) so why not implement it across the board? Standardisation and enforcement of standards is a boon to users, not the opposite.
