HSPEC – CPU MEGA LIST

INTEL CPU MEGA LIST

Here goes –

Some background.

In 2022 I released a CPU upgrade guide for the Z840, and one resource that I found really useful was the table that I made of the Haswell and Broadwell CPUs – especially because I included the Ebay pricing range at the time. Nearly 2 years later, prices have changed and new opportunities have arrived.

So inspired by that table – I give you the “CPU MEGA LIST”.

Now it’s not an all-encompassing list because there are just too many Intel Xeon CPUs to cover – but I settled on CPUs that are relatively abundant and that meet the power limits of the relevant HP Workstation systems.

CPUs are filtered according to published single CPU PassMark Scores – from highest to lowest.

An * means there are no PassMark entries for the CPU or only entries for a variant of it (e.g. Platinum 8160 but not 8160T etc.).

Technical note:

Keep an eye out for “ES” or “QS” in the listing descriptions. Engineering Samples (ES) often are early release CPUs that Intel sent out for testing purposes. They may or may not have full functionality (e.g. lower clock speeds etc.), and they are often locked to certain systems only. Quality Samples (QS) are close to retail fully functional CPUs that are not locked to certain systems. Read product descriptions carefully (any listing can claim ‘QS’) – check actual CPU photos for the model – check HWiNFO / CineBench screenshots. ‘ES’ CPUs often read with strange names like “CPU 0000 @ 2.2GHz ES”. I would avoid those because 9 times out of 10 they will not work in your system.

HP Z8 G4 Workstation

(also suits HP Z6 G4 – but the Z6 G4 can also support certain LGA 3647 based Intel Xeon W CPUs; note, the HP Z4 G4 uses LGA 2066 and thus is not compatible with these).

HP Z820 Workstation –

LGA 2011 (also suits HP Z420 and Z620; but note certain E5-16xx V1 / V2 Xeons also work in the Z420 and Sandy Bridge V1’s can also work; some motherboards do not support these – check carefully your motherboard version):

HP Z800 Workstation –

Dual LGA 1366 (may also suit HP Z400 and Z600; Intel Legacy CPUs – L, E and X – I ignored the older 5500 generation but some motherboards do not support these – check carefully your motherboard version)

More info – Legacy Xeons:
