Decoupling was EXACTLY done so you could backport. Bringing it to a next gen process is much easier. It was very clear from the words used in the interview that they wanted to prevent a future repetition of stagnation in architecture when f.i. 7nm also turns out problematic.
And regarding the...
Dude seriously. It is literally stated in that quote that Willow Cove 11th Gen will be extended to 8-core products. Rocket Lake is *not* Willow Cove.
The H-range is based on Willow cove and 10nm SF. Doing anything else for their top of the line H product - seeing Rocket Lake's horrible...
It is widely known rocket lake H has been cancelled. For mobile it would be a powerhog. Not sure why you think they would launch a 14nm previous gen Sunny Cove backport for mobile when they also have Tiger Like on 10nm SF.
No way in hell it was just 18 months ago. Remember Rocket Lake is delayed by half a year. Add a year on top of that since you need about two years if all goes according to plan.
Not bothered to look it up but I seem to remember JIm Keller stated they succesfully decoupled process from design...
Ok I'll break it down more simply for you then. Multicore performance is just slapping more cores on within the same thermal design envelope (TDP), so a 4+4 core ARM processor would offer similar MC performance to a 2+4 core Apple A14 if perf/watt is similar and both are designed around a...
That's not really much of a problem rather than a choice. A77 isn't much worse in perf/watt because they are/will be fabbed on the same process node. That's not what this is about.
Perf/watt might matter for the smartphone as there is a certain top TDP that has restrained the Apple designs, but...
This is all true but then you frased your remark a bit unclear. Question isn't what they can improve (we've seen Apple show what can be done) but how.
Clearly Microsoft thinks they can, and as to who: I've read (was it on these forums?) that the entire SPARC team moved to Microsoft after Oracle...
This is a strange thing to say if you are even a bit familiair with the ARM design landscape. Qualcomm uses the stock ARM designs and although they are good Apple is miles ahead and showing the potential of ARM. Just riding on the default ARM option offered by Qualcomm won't get Microsoft any...
Again, it's not twice as much when you look at the full transistor count including uncore. Also: various parts have various density and transistor size does not 1:1 translate to higher density. This is something many people have trouble to wrap their head round but transistors beyond their...
Then you haven't read anything about Intel in the past two years. With the announcement of the Cove architectures they explicitly mentioned they decoupled architecture form process node and the internal revolution it caused. Rocket Lake is a first example but Alder Lake and it's variants might...
firewolfsm is correct. You don't understand where the improvement comes from and assume it's from increased density. the 14nm+ and beyond density is lower then the original 14nm and has remained such. The improved power usage is mostly from reduced leakage and lower voltages and to a lesser...
I know it's just anecdotal evidence, but as a small engineering office we also moved all our personnel to laptops in the summer. It was just two additional laptops since most already moved to laptops but that decision really simplified our IT and support structure.
Any way you slice it this will not be the case with Alder Lake given the many different configurations tested and the rumored SKU's. So the question is rather, how to make sense of 4 tiers when there are so many different core and thread counts.
Comet Lake, whatever you might think of it, had...
I saw the Moore's Law is Dead episode of the Redwood Cove leak/rumor but the Alder Lake SKU's dont make sense to me.
Personally I'm thinking in each segments (i9/i7/i5/i3) there will be a distinction between k and non-k not just in clocks and overclocking but in secondary cores to further...
To answer my own question, the reason we don't have Tiger Lake S for 2021 IMO was the panic mode they were in. Rocket Lake, in spite of the massive effort, was their most safe bet to have a somewhat competitive core available in '20/'21 with the alder lake core competitive enough to remain...
That's assuming they started the backport effort around the announcement but it should have been at least a half year in the works by then. So with a launch in Q1-Q2 '21 it looks more like a 3 year timeframe to me.
Why do you leave out Tiger Lake S? Comet refresh is out of the question but I don't understand why they didnt invest more in an 8c Tiger Lake S part. Tiger Lake has the frequencies for it, if they can do 4.8 on mobile they should be able to hit 5 on the desktop.
Absolutely and the fact backporting was such an incredible effort was the reason they were very careful in their wording not to raise any expectations. Still to me it was clear such a backport effort was indeed already started and sunny cove would be the most likely candidate for that.
Now that Rocket Lake based on Sunny Cove is officially confirmed I'd like to remind @jpiniero and @DrMrLordX to the discussion we had after the sunny/willow/golden cove introduction in december 2018 whether it would be sunny or willow cove that would be backported. I was wayyy to optimistic...
I Have to say I'm surprised seeing AMD still having only 20% of the desktop market and even more surprised mobile where the advantage is much less pronounced has the same marketshare. Since there is no DIY mobile market AMD's OEM market share for desktops must be even lower than mobile. Can't...
The premise of this thread leaves me massively underwhelmed.
Pretty sure 1 euro today feels like 1 euro 20 years ago, and yes you can buy more with your income today, that's called progress (and yes I'm familiar with the concept of inflation but it doesnt work like that 1:1).
Anyhow I bought...
Me too. But I heard ocean cove could be yet another IPC/perfromance leap? Does anybody have any rumors /info on ocean cove/meteor lake, when it's expected on the desktop (year after alder lake-S?) and whether it will be 7nm for the desktop as well? sounds a bit too optimistic to me. I'm...
My point is this 7% difference doesn't show in the geekbench 5 processor charts so it seems the OP is cherry picking GB5 results and not the median results provided by Geekbench themselves.
The 9900K scores an average of 1334, which scales pretty good from the baseline 3.6Ghz 1000 score for...
Yes i agree they need Rocket Lake NOW. Still stunned they let it come to this. I had a hard time believing jpiniero 2yrs ago when he claimed comet lake was yet another skylake iteration but they couldnt even get sunny/willow cove to the desktop one year later.
I read some time back some heads...
Interesting, that would be a break from their usual modus operandi the last 5+ years. Like many I have a hard time seeing Rocket Lake only have a shelf life of half a year. It's probably delayed by half a year but my guess is they can't afford to let a full year go by.
Anyhow, I would be the...
yes i know but on average I believe it was about 2-3% faster in Geekbench..?
what i also dont understand in this list is the big performance delta between skylake and coffee lake (~7%). What I remember between kaby lake and skylake IPC was identical and coffee lake vs kaby/skylake was about...
I think people here are failing to take into account the distinction between mobile and desktop. Desktop usually is about half a year behind mobile.
My money is on Alder Lake release for mobile late '21 and early '22 for desktop, so I don't see how both (Rocket Lake & Alder Lake launch in early...
I would take everything jpiniero says about RKL-S with some spoons of salt.
He denied for the longest possible time there was any kind of sunny/willowcove 14nm backport. Probably as recent as half a year ago it was yet another coffeelake iteration according to him. Since it became clear it was...
You are being facetuous here. TDP has nothing to to with power? :tearsofjoy::tearsofjoy::tearsofjoy:
Maybe you should check the last word you bolded. Also look up the meaning of the other two words thermal and design.
The original meaning of Thermal Design Power was the maximum power output...
It's not about extreme use cases it's about *your* use cases. For me, as a civil3d (autoCAD) user, single threaded performance is important as AutoCAD doesn't scale well over multiple threads. That's like 90% of my heavy lifting usage that's directly impacted by single threaded performance.
You need TDP to match / fit your power supply, it's not just thermals. Especially for laptops / SFF PC's the power supply isnt that buffy. It's really great they allow you to specify PL1/PL2 states, AMD could take a cue form that. But to pretend it's not important for your build is a plain lie.
The single core turbo isnt relevant in this "BBT" rating as it doesnt say anything about the non-turbo speeds of the other processors. The T should be the all-core turbo at 4.3 GHz.
I would refrase it as
Base 1.2 GHz at 12 W
Medium 3.0 GHz at 28 W
High 4.3 GHz at 50 W
where every mobile chip...
Not sure if it was discussed here already but what's the second die on the Tiger Lake chip? I always assumed it was the graphics but the die shot in the Anandtech article clearly shows the die still has integrated graphics.
Isn't windows reporting each module as two logic cores? Since the OS determines the thread scheduling seems to me that how your OS reports them is what counts (pun intended). Not sure if the same accross Linux and Hackintosh.
Then again, SMT doubles your logic cores so to make it apples to...
I have a SFF with an under/overclocked Core i5-8600K running between 3.3 and 5GHz. Underclocking the all-core setting to keep it below 65W, and overclocking at 1-2 cores to get maximum single threaded performance. I also had to disable one core to hit that TDP mark.
Moving the guts over to a...
