The problem being the average consumer doesn't have a clue. They simply see higher frequencies and assume it's better. I had a friend call me because he wants a computer upgrade and he seriously couldn't comprehend that a new ryzen could possibly be faster than an older gen core processor. "But it's 200mhz faster so it has to be better". The second I mentioned IPC I could already tell he didn't have a clue how that could possibly offer better performance. I'd assume most people on here understand the nuances better than most typical consumers.One thing that is often overlooked during the 14nm vs 10nm frequency comparison is that the frequencies we know now about the 10nm cpus are only those of the 15W U series processors. It is a mistake to project anything from them. There are three things to note.
(i) U series processors’ frequencies have always been considerably lower than desktop ones. Typically around 500MHz lower (+/-200MHz) with the difference often exceeding 1GHz when you mildly OC your desktop cpu (‘stock volts’, air cooling).
(ii) Historically whenever a new generation was introduced, the single core speed of the mainstream flagship in the mobile platform was between 3.0GHz-3.5GHz. If the Icelake U cpus came just after the (already mature) 14nm+ Kabylake U cpus we would actually be talking about the incredible jump in single core frequency, going from 3.5GHz of the i7 7500U to the 3.9GHz of the i7 1065G7. We would be talking about how great the 10nm process is compared to the 14nm one.
(iii) Just because Intel spent more time on the 14nm keep optimising for frequency, it doesn’t mean there is something wrong on the cycle of the 10nm process in terms of the achievable frequency. Frequency improvements will be achieved as the process matures further, the same way it happened with the 22nm and the various iterations of the 14nm processes in the past. I doubt that the yield problems we have heard about the 10nm process are frequency-related problems. Intel can probably already produce Icelake desktop cpus with pretty decent clocks (like 4.5Ghz or so). Instead the yield problems seem to have been “misprinting” problems. In other words, if they went ahead to produce larger dies of Icelake cpus (like 8core or 10core ones) they would be throwing a lot of them away because they are straight-out faulty, not because they can’t hit a certain high frequency.
(i) The IPC gains of Willow Cove compared to Skylake should be massive - like around 30%. A 10% loss on frequency is therefore more than compensated.
Well IPC is actually much more nuanced. You see IPC is a per workload metric and what is quoted as an IPC increase is the average uplift across several workloads. In workload A it can be 10% faster, in workload B 20% faster and in C 30% faster, the average across all three is 20%. Consequently, it largely depends on your test suite, which tests are included in that suite and how many. It is similar to saying it is X% faster in gaming. But in fact it depends which games you compare and how many you include in your test suite. And that assuming you won’t be running into a gpu bottleneck scenario.The problem being the average consumer doesn't have a clue. They simply see higher frequencies and assume it's better.

Perhaps not, but don't forget that Intel Launched 14 nm Comet Lake for the laptop performance segment after 10 nm Ice Lake. This is basically proof that their current 10 nm node cannot deliver the clock speeds to compete at the top of their product stack.One thing that is often overlooked during the 14nm vs 10nm frequency comparison is that the frequencies we know now about the 10nm cpus are only those of the 15W U series processors.

Uh, that is yield.Instead the yield problems seem to have been “misprinting” problems. In other words, if they went ahead to produce larger dies of Icelake cpus (like 8core or 10core ones) they would be throwing a lot of them away because they are straight-out faulty, not because they can’t hit a certain high frequency.
I'll believe it when I see it.(i) The IPC gains of Willow Cove compared to Skylake should be massive - like around 30%. A 10% loss on frequency is therefore more than compensated.
Though it probably won't help with someone who doesn't understand the concept of IPC, the analogy of horsepower works quite well. Just because one engine produces more torque or revs to a higher RPM doesn't necessarily make it more powerful than another."But it's 200mhz faster so it has to be better". The second I mentioned IPC I could already tell he didn't have a clue how that could possibly offer better performance.
True. When Broadwell got delayed, Intel basically canceled the desktop parts and went straight to Skylake.I am not holding my breathe for a second Intel refresh/launch this year, even without the supply chain issues hampered by coronavirus it was not realistic to see two launches less than 9 months apart.
For a desktop CPU? That's just mad!Alder Lake is the codename for Intel's upcoming 10nm desktop CPUs that are rumored to adopt the hybrid architecture like Lakefield. Rumors point to a 16-core configuration comprised of eight big cores and eight small cores.
