    I think Ryzen TR and Ryzen 5,7 will be crushing Intel.

    On prices, yeah. Not on performance!!

    My information was incorrect, they can be configured at max. 25W TDP, not 28. At load on all 4 cores they probably just hit base clock speeds of current 15W U series CPUs (2.7-2.8GHz).

    While thermal throttling it will fallback to stock clocks and increase stutters during intense load. I can barely hit the TDP limit of HQ CPU because mine tops out at 37W to be precise instead of 45W.
    We'd see TDP limit hitting frequently in TS. Don't you think @Mr. Fox @Papusan @hmscott

    I hope they won't run too bad under heavy iGPU load, in machines without dGPU or eGPU...

    indeed under sustained load they can't keep the top turbo boost clocks and settle on lower clocks once the tdp limits of 15W set in . It is possible to have a tdp up configuration of 28W which would be better on sustained loads but unlikely any vendor will implement that.

    In the first link if you read the article

    "The CPU maintains high Turbo speeds for a short while, which is corroborated with a package TDP of 25 W or higher, but after a few seconds it drops to the standard 15 W TDP and the frequencies drop to 2.2 – 2.3 GHz."

    So you have a base speed of 1.6ghz and are getting a turbo speed that is 600-700mhz above the base clock. You can't expect it to turbo to its max speeds as those are quoted as single and dualcore turbo speeds, much like the current 15W cpu's. Also in the Ultrabook review article they tested 2 i5 8250U notebooks. 1 with dedicated graphics and 1 with integrated. As expected with dedicated grapgics the cpu could turbo boost higher and longer resulting in better performance.

    Fact is there is ZERO downside with these new CPU's even though everyone keeps complaining that there is. They have been proven to be faster than the existing dual cores while keeping the same power consumption.

    Indeed it is a great performance improvement over the dual core 15watt chips, especially in multi thread operations. The question now is the thermal profile, if it generates more heat or is about the same as the present dual cores.
