Definitely ES CPU - which is why it is labeled “Intel Confidential”. Was never intended to be released into the wild.
The CPU is identified by the S-spec, which is a four character code. In your case the S-Spec is QHZH coded onto the lid. It’s called “S-Spec” because the first character is an “S” for retail CPUs. ES CPUs generally start with “Q”.
You can look up what is known about most CPUs on CPU-world.com. Info for many ES CPUs is included, especially for final qualification ES CPUs. For many other ES CPUs, like yours, little info is available or published. This could be because it was such an early trial device that nothing got released. Or perhaps it was a “special” CPU that went out under an NDA agreement to a very large customer (e.g.,: AWS, etc.).
They often work fine. Or they don’t... Things like imperfect clock rates (1.9Ghz for a CPU you’d expect to run at 2.0Ghz or refusing to run memory at full speed). Other times the issues may be insidious, like unprepared arithmetic faults.
