AMD Ryzen 7 Extreme Edition Spotted - 8 cores - 4.3 GHz - 15 Watts Ultra-portable?
The news never stops for and from AMD is seems. This round the UL ORB is listing a reather curious tagged processor from AMD,. a Ryzen 7 Extreme edition?
Thai PC aficionado TUM_APISAK stumbled into it, and claims this might be a "Renoir" based product. If you look at the base clock of 1.80 GHz we're inclined to say it has to be a mobile part. However, it can boost all the way up to 4.30 GHz. The processor gets 8 cores and 16 threads enabled for SMT. This "Extreme Edition" processor looks to be running 100 MHz faster seen from the Ryzen 7 4800U, which is locked in at 15-Watt for TDP with a 4.20 GHz max boost. Yeah, TDP is a flexible thing these days. Fast ultra-portable anyone?
AMD Ryzen 7 4700G Renoir spotted, 8c/16t and Vega'ish Integrated GPU - 05/10/2020 03:09 PM
If you have read our Ryzen 3100 and 3300X reviews, you will have noticed that one of my arguments was that these procs likely would have been better off if they'd had an IGP (integrated graphics proc...

I meant engineers don't seem to be failing at making proper cooling solutions.
Well even for cooling purposes it is misleading, since 4.3GHz isn't sustainable for very long. But yes, actual power draw would be much appreciated too.

My 2600X is listed @ 95w but if you look at the average over time then the actual figure is only 22w but only if you fix the stupid Ryzen Power Plan from 90% always on down to 5% and use the PC 80% of it's usage isn't gaming but just browsing and watching movies an stuff.
So maybe it's an average usage scenario over time. Must be that because no way is it using 15w while boosting past 4gigs.

Cooling is only 1/3 of the problem. Keep in mind too that people who buy a CPU like this aren't depending on burst performance; they're intending to do heavy workloads. Battery life and getting the performance you paid for are more important.
15W for a max TDP is great - that's the kind of power consumption that will last you for hours with predictable performance. But I wouldn't be surprised if this CPU exceeds 65W. The cooling solution obviously will prevent it from using that much power for very long (especially if the heatsink is rated for a 15W TDP), so you're paying for performance you won't get often. The entire reason you'd buy a CPU like this over a lower-clocked variant is so you can get tasks done quicker, but you're not saving that much time if it keeps throttling performance. If you buy more accessories to keep your laptop cooler, then you are defeating the portability of it.
Also remember that efficiency doesn't scale linearly with clock speed. So even if you're able to do 10 minutes of work in less than 5 minutes, you could be using up more than 10 minutes of power. This is especially true in a laptop, where the fan would have to work disproportionately harder than it would on a lower-clocked model. What's the point of having a higher clock speed if you could be limiting your total performance?
Of course, the key word here is "could". It's possible that this isn't significantly more inefficient, especially if the cooling solution prevents you reaching inefficient clock speeds.

Doesn't seem very extreme to me.

Is this not the 4900U or whatever that chip was that's yet to release for the mobile line yet, to tackle intel's top-end back into the trash-heap where intel belongs?
