1.4 GHz? Really?
I know it's quad-core but still it just seems too low unless I'm not understanding something

his isn’t true. Higher base clock (like 2.4 for example) means that this frequency is guaranteed, when the OS doesn’t need that kind of power it’s going to run in a lower power state (and thus automatically lowering the frequency to 1.4-0.8ghz).The turbo boost is still 3,9GHz so I wouldn't be too worried about it, the juice is still there when you need it. Higher base clock = more heat and higher power consumption.
Would like to hear.I got one coming on Friday, so we'll see how it performs compared to my 2018 Air and 2015 15" MBP. I'm guessing it will be a snappy little machine, but who knows.
Need some differentiation to make people justifying purchasing the 2.41.4 GHz? Really?

Also I'm wondering if I like TouchBar at all and is CPU going to be any faster than in MBA 2018 in real life (or is it even faster than in Pro 2017 non TB model)?
I think Intel now does some jazzy stuff where they quote boost clocks which can only be achieved when one core is under heavy use, and the others are largely idle - the actual sustained boost on 4 cores will be lower. I don't know if the reverse is also true, and '1.4GHz' is the base speed when all 4 cores are in use? Maybe if two are being used and two idle, the two can run at a higher base speed?T

If the baseclock is 1.4ghz, it means that intel guarantees 1.4ghz but anything beyond that isn’t guaranteed
Iris Plus 645 suggests 15W - the Y series only have UHD graphics, and the 28W U variants like in the 4 TB Pro use Iris Plus 655.Isn't it mostly running on one core during normal tasks and since both MBA 2018 and new Pro TB 1.4GHz are with the same generation 8th Intel i5 CPU? Sure MBA is only dual core but still when considering single core speed MBA is 1.6 and new pro only 1.4GHz. Also is it going to be 15W TDP in Pro or something less, or is the cooling efficient as in higher speed Pro models? There are many things that can cut the actual power. We will see that but I'm always cautious when something sounds too good to be true, and knowing Apple they know how to make difference between cheap and expensive models...

How are you using it, that you feel the laptop's clock rate is too low?still it just seems too low unless
That's good, so if you've got a moderate load that's better served by two cores running higher, I guess the software can dynamically use the CPU cores as it sees fit?Thats how boost clocks were always advertised. In fact, turbo boost traditionally worked depending on core utilisation. Nowadays they just use power/thermal limits.
The way how Intel defines the nominal clock is the minimal clock that the CPU should be able to sustain when running (quite Intel) a "complex workload" provided that the power and cooling system can manage the CPU's stated TDP. In other words, under 100% CPU utilisation (across all cores), an Intel CPU is expected to draw exactly its TDP worth of power and run at frequency that equals or is higher than its nominal frequency. That is the performance guarantee Intel gives.

I believe Air 2018 is only 7W and just heat sink but still Geekbench score is just over 4000 single and about 7400 multi. So Pro 1.4GHz might not be that fast in real world single core situations but who knows. It will be interesting to see first tests.Ye you can’t really compare the clock speeds 1.4 to 1.6 because the 1.4 28w and cooled whereas the 1.6 is 15w and not cooled.
3.9 is a huge jump I doubt it will touch that maybe 3 for 5-10 seconds at most then clock down because of the themal constraints.
Obviously it won’t compete with higher end chips but if I was to estimate a Geekbench score of roughly 4000-4500 single and 12000-15000 multi.

I will post some benchmarks tomorrow for 1.4GHz quadcore CPU. With and without liquid metal
