I would be quite nice if they actually advertised the particular type of CPU core you rent, rather than some abstract unit of computation. Or at least some kind of performance baseline.

For example, in us-west1-a, you're getting a 2.2 GHz base clock E5 Broadwell.

I'd rather wait for Ryzen. You won't know which Skylake processor you're getting - the gimped one or the non-gimped one. AMD tends to keep their features consistent across the line.
Are these E5-skylakes?
"Yes", most systems are Google, including those in Cloud, are dual socket. [Edit: To be clear, we're not sharing the SKU, but this is a real server-class Xeon]. Disclosure: I work on Google Cloud.

In fairness, there's precedent. Though that was the FPUs in Intel processors, not AMD. So it's not very good precedent.
Intel's FDIV bug was an outlier. Besides, nowadays most of the ISA is implemented in microcode[1]. There are two advantages to this approach: 1) it is much easier to verify the microcode unit (it's simpler/smaller), and 2) it allows CPU vendors to "fix" ISA implementation issues post-release by issuing microcode updates. [1]: ISA => microcode is equivalent in some respects to C => LLVM IR
There was also an issue with transaction memory with both Haswel & Broadwell. The fix was to disable TSX support via micro code update. I wouldn't call disabling a fix personally. I doubt Intel even compensated the folks who bought it for the TSX support.

Please relay back to your team that the moment you get Postgres for your Cloud SQL product you'll get a lot of AWS converts.
Out of curiosity, why would you prefer Google Cloud to AWS?

Are E5 Skylakes available exclusively to Google? Can't find E5 v5 on Intel's site: http://ark.intel.com/#@Processors .
Skylake Xeon E3 is on the current older server chipsets..
Purley is supposed to be a significant improvement.
Just for reference, since you don't choose your processor explicitly on GCP, but instead choose your zone with homogenous processors, here is their current processor/zone layout: https://cloud.google.com/compute/docs/regions-zones/regions-... Since some GCP engineers are watching: Presumably we'll see some new zones to provide these processors, or will it be a limited release within existing zones? And if so, will yo…

How much confidence do you have that Rev. A Ryzen parts will even work?
That's a bit too extreme, don't you think? Disliking AMD is one thing, but claiming that the entire initial run of an AMD processor might be faulty is just silly. My guess is that you have no idea how much effort goes into verification and testing of something as complex as a microprocessor. A significant chunk of NRE costs goes into verification and test AFAIK.

Not really. AMD's Phenom was a flop and the initial batch had a horrible TLB bug. Their FX processors were also hugely hyped and hugely disappointing.
Regarding your criticisms of AMD's past processors, are you coming at this from a consumer standpoint, or are you just disappointed with their architecture and/or implementation?
I ask because the Phenom II seems quite loved by its users[1], and the FX series was also quite good for its price. I had a FX-8320 in my last PC and it was quite a capable CPU in my opinion, and many others seem to agree[2].

Purley is the big Skylake based server platform chipset reset for Xeon E5 and higher so Google must have early access to it. Skylake Xeon E3 is on the current older server chipsets.. Purley is supposed to be a significant improvement.
