AMD Confirms Raven Ridge APUs Boast of Mobile XFR Technology

It's been confirmed by AMD that the company's XFR (eXtended Frequency Range) tech that has made its way to the company's desktop Ryzen CPUs has seen its way i to the company's APUs as well, in the form of mXFR. This much was to be expected - mobile form factors arguably represent the best platform for dynamic frequency changes, marrying best performance and power consumption whenever one or the other is required. Speaking to TechReport, an AMD representative confirmed that Raven Ridge chips will feature mXFR capabilities depending on the platform they're implemented in, and spoke in particular of the Ryzen 5 2500U + HP ENVY x360 capabilities on that particular front.

"Not all notebooks with the AMD Ryzen mobile APU will offer the necessary thermal solution to enable the performance upside of mXFR," the AMD representative said, "but the HP ENVY x360 featuring the AMD Ryzen Processor with Radeon Vega Graphics is the first solution to do so. Users will look for "amplified mXFR performance" in the marketplace should they desire a laptop that offers this capability." This means that while typical TDP for Raven Ridge solutions should stand at the 15 W value, power consumption of the CPU + GPU combo can increase its TDP up to 25 W given particular workload, battery state and temperature conditions, which should increase performance in detriment of battery life.

Sounds very interesting and I hope we will soon see proper benchmarks on real life scenarios and more!

Come on AMD, bring us Basilisk APU's already!

Not too many models out with Raven Ridge APU yet, has HP got exclusive deal from AMD?

Erm, AMD confirmed that there's mobileXFR in Raven Ridge's when they launched them. What was new is that HP Envy uses a Raven Ridge with mXFR enabled, not that RR can have it.

Now all we need is upgradable notebook cooling solutions (besides your usual chassis modding) :D

Don't count on it. Any source with those codenames are obviously wrong and outdated. Like saying Bristol Ridge has Zen cores and launching in 2016. And I don't really know if there's much point it to besides fanless designs. Raven Ridge can go down to 12W. These supposed Cat-core replacements are probably abandoned somewhere along with ARM cores.

No. Lenovo and Acer have announced models but they're not really rushing to get them out. There aren't any OEMs expecting any major sales so they only hope to sell some cheapo laptops while maintaining their relationship with AMD. We might see more models announced at CES but I'm not really expecting any OEMs to take and gambles or try to raise bar for AMD laptops. I'm only expecting more of the same.

AMD is "confirming" more things than they're actually releasing. Investors have already stopped paying attention, so what's the point?

We'll we finally see a Ryzen-powered business PC by February? Or did vendors decide this platform is not worth the fuss and they're waiting for Zen+ already?

Correct me if I'm wrong: are there any high-end notebooks built around Zen with screen <= 14"?
I know about HP Envy x360, but it's just in the 15" variant.

BTW: HP is not exactly proud of their Ryzen products. Nothing here:

Looks like there won't be any dual core Zen based APU's. From the looks of it, it'll only be Stoney Ridge, basically single threaded IPC tuned Bulldozer at 28nm for the low end.

Exactly. This "news" report is a misunderstanding by the editor, no more. AMD talked plenty about mXFR at the RR launch.

AMD confirmed this feature when they launched Raven Ridge. The new piece was that HP Envy x360 has mXFR enabled, but TPU somehow missed the whole point

Another stupid headline that misses the actual news - HP x360 is set to use 25W TDP. We knew RR APUs use mXFR since they were announced many months ago.
