John, 621/622/624 all don’t have it either.
Since this is 741, it’s the base model chipset.
I’d be looking for 747/749 if the naming convention holds at all.
Also intel offers dedicated accelerator cards for QAT as well, since a huge number of Xeon customers don’t even know what QAT is.

I’m wondering why QAT wasn’t made available for this chipset; you’d think that it’s hardly a differentiating feature, yet if it really was special, then removing it from a chipset then makes it a whole lot less useful.

So either Intel thinks it’s a big deal that you must pay extra for while nobody cares, or this chipset will simply never go beyond desktop usage. (and even then, no QAT when you run high speed networking and desktop virtualisation seems like a waste… maybe this is just a ‘binned’ PCH where QAT was broken and is now fused off?)

Funny: With Cooper/Ice Lake Intel barely bothered to slap a “A” to the C621 chipset. Now Intel is skipping 630, 640, 650… and jumping all the way to 740.

Of course, Intel numbering is meant to CONFUSE the customer, not to help understand and navigate the stack.
