Noticed the base clock speed on those is only around 2.x Ghz

That's standard. The i7 8550U and 8650U is 1.8 and 1.9 respectively.

 

 

I guess it's to keep power consumption per core down.

Yeah... well it has to fit in that 15W envelope. But they can ramp single core performance right up. Unfortunately these aren't the 12nm refresh so they won't be able to turbo as high or competitively.

From this - my i7 7700HQ vs those new Intels. They have done well to lower power consumption, but my i7 7700HQ won't be obsolete for a while.

This is AMD and GloFo's estimation of how far behind they are now in process competitiveness.

AMD is deploying a patch for the second Spectre CPU vulnerability

 

While Intel is at the center of the Spectre/Meltdown fiasco, AMD's chips are also affected by the CPU vulnerabilities. The company previously said that the risk of exploit using variant 2 was near zero due to its chips' architecture. But in its latest announcement, it said that because both variants are still "applicable to AMD processors," it also plans to release patches for the second variant to be absolutely safe. AMD already provided PC manufacturers its fix for the first Spectre version, and Microsoft has begun rolling it out. The chipmaker also said it's working with Redmond to address a problem that delayed the distribution of patches for its older processors.

 

Since the second version of Spectre needs a different fix, AMD will provide its customers and partners for Ryzen and EPYC processors with a patch for its chips starting this week. Firmware updates for its older chips will follow in the coming weeks. If you use Linux, you might get it sooner than you think, since Linux vendors have already started releasing OS patches for the second variant. You might have to wait a bit if you're a Windows user, though, since AMD is still working out distribution timing with Microsoft.

 

Despite deciding to release a patch for version 2, the company reiterated that its chips' architecture will make it very difficult for attackers to use the exploit. It also maintained that Meltdown isn't applicable to AMD chips at all. AMD's processors aren't "susceptible" to Meltdown, the chipmaker wrote, "due to [the company's] use of privilege level protections within paging architecture." Since "no mitigation is required" for variant 3, it won't be creating a patch for the vulnerability.

 

Update: AMD clarified that it never said its chips were not susceptible to variant 2.

 

AMD slips after Microsoft stops ‘Meltdown’ patches for PCs with its chips

 

Idiots at Microsoft are patching CPU's that don't need patching.. and sending them out to users without lab testing them first.

To be fair, Microsoft wasn't expecting that many people with those old Athlons out there. I got rid of mine ages ago.
