More stupid than spending millions of dollars porting Tigerlake back to 14nm, for a small market of enthusiasts?
The alternative is doing nothing. Also, it'll cost millions making a ringbus version of SKL-X, the AVX-512 part of which will be insignificant for majority of consumers. I also can't imagine it'll reach the clocks 9900K variants will reach so it'll lose anyway.
That's the crux of it. Rocket Lake-S is going to lose on IPC and core count, and might not do much better in clockspeed either, but at least Intel will have a new product to replace Comet Lake-S that has some improvements. Rocket Lake-S could have been out by now had Intel created a backup plan for 10nm failing as badly as it has. If it were on the market right now, it wouldn't be so bad. The only thing wrong with the product is that it's delayed until 2021.The alternative is doing nothing.
You give him far too much credit. Netburst was such a failure that Intel did go back into their portfolio, dusted off blueprints for older uarchs and worked off of that to deliver Core. I wouldn't necessarily expect any major upset like they did with Core, especially not with their corporate offices becoming a revolving door of people coming in and leaving, or rehashed products over and over again pushed to their limits.For anyone not running at 5GHz the jump to a new architecture would be fabulous. Think like… uh 80% of the CPUs they sell, not some high end i7-i9 or unlocked parts.
Also the fact that finally we could get new instructions and advancements rather than a 5 years old zombie. Man if Piednoel really did suggest for backporting Ice Lake a couple years ago and they didn't on some positive 10nm outlook that really got to hurt now, especially with Zen 3 incoming.
AMD kept running on Bulldozer for desktop because they had limited time and money so rather than 8 core Steamroller or Excavator we had ever increasing clocks on outdated parts, while they solely focused on Zen.
I find hilarious a company with 10 times as many resources such as Intel can't push all the levers and just implement every new trick they have, rather than have them dusting in their portfolio.
IMHO: we should have a tiger successor coming out, not some infinity lake. It's impossible they aren't ready arch wise, it's only a node issue.
If anything even newer is boiling inside I sure hope it's at least 50% better core/core, or totally disruptive to the CPU world like reverse multithreading actually working.
Doubtful. Willow Cove isn't supposed to come with much of an IPC increase over Sunny, if I recall correctly. I think most of the TGL vs ICL leaks we've seen thus far are skewed by bad boost clocks on the ICL parts.
Zen3 allegedly has a 17% increase over Zen2 in aggregate (12% int, "up to" 50% fp), so we'll see.
Exactly. Intel is stuck on 14nm longer then they expected and Intel has finished new uarch Willow Cove. So why not backport it for 14nm instead 5 years old Skylake? There is another big advantage: WillowCove@14nm will probably reach clock around 5 GHz. Together with +20% IPC over SkyLake it's highly probable that RocketLake will keep gaming crown on Intel side. Will RocketLake be power hungry? Yes, as hell. However for desktop/gaming this could be awesome CPU. IMHO more powerfull than Zen3 (at same core-count).Also the fact that finally we could get new instructions and advancements rather than a 5 years old zombie.
Wonder how many times I'll have to say it at this point.Why not?
Nah, undervolting headroom on ICL-U laptops tends to be really thin compared to 14nm chips. Intel are binning quite hard to get ICL worthy chips, and the ones that can pull off the clocks they get can barely do so.10 nm is a broken node. They are jacking up the voltage to get as many chips as possible.
That's just basic logic, or science. On the other hand, Intel has done the math, and are apparently pleased with the result, contrary to the doom and gloom in here. I'm intrigued to see what this product brings to the x86 landscape.It's just simply a fact that wider architectures are less power efficient.
Why do you think only about power efficiency? Desktop is not limited by TDP as high as 15W laptops. Yes, RocketLake @ 5GHz will consume +20% more power than Skylake, probably around 200W. But who cares? We talk about same kind of product like 9900KS, don't we?Why is everyone suddenly assuming that Intel would be able to extract 20% more performance at the same power out of Willow Cove on 14nm compared to Comet Lake and, by extension, also 20% more power efficient than Sunny Cove on 10nm?
So I'm going to assume for the rest of this post that Willow Cove is as efficient as Sunny Cove, even though we know it's not. It's more efficient.Why do you think only about power efficiency? Desktop is not limited by TDP as high as 15W laptops. Yes, RocketLake @ 5GHz will consume +20% more power than Skylake, probably around 200W. But who cares?

Oh don't you worry, if Rocket Lake is a backport, it will have it's use, just not for desktop. Only a very minor perf/W gain for desktop.That's just basic logic, or science. On the other hand, Intel has done the math, and are apparently pleased with the result, contrary to the doom and gloom in here. I'm intrigued to see what this product brings to the x86 landscape.
