Intel Xeon Platinum 8380 Processor 2P (Ice Lake)

ok, how about intel sponsored PR? I suspect that's what he is.

He seems to know an awful lot about intel specs and dodge any question related to whether he's affiliated to, sponsored, or paid by them. i thought the forum rules used to say company reps should identify themselves as such, or has that dropped off in recent changes? One to bring back if it has.

It's not even worth comparing it to the top-end (and power competitive) AMD part The 7763 has lower RRP (slightly) than the 8380, and the 7713 used in this review is both substantially cheaper and uses considerably less power (~100W on a 2-s system per TDP). I figure that difference in power consumption adds up to ~£200/year (assuming 30p/kWhr, as datacentres have to pay twice for power - coming in and getting heat pumped out), which is a lot to pay for a slower chip

A few extra notes.

At the top end, AMD wins through sheer compute muscle. There is little doubt about that.

As we had to retest on Ubuntu 20, we chose 7713 from AMD. It still ran rings around the 8380 in CPU-specific tests.

We do say that all this release serves to do is enable Intel to play catch-up to AMD.

Actually, it would be far more interesting to see how mid-core offerings compare against each other; not everyone is buying top-bin 40- or 64-core parts, respectively.

I can only see Intel getting closer to performance parity with AMD's best through upcoming Sapphire Rapids.

These Xeons would have been good in early 2020. In 2021, however, the Lord Mayor's show has passed by.

That seems to be the general market opinion!

I don't disagree with the choice of chip - it's just amusing how far intel has fallen. The top end epyc would have been like comparing an FX 8-core to the intel HEDT chip of the time!

The mid rung chips would make an interesting comparison - could you also please include power draw numbers? For something running 24/7 differences there can add up fast

Fair point. I've dug out the results files. Bear in mind review servers are not optimised for power, so Dell, Lenovo, et al, may have lower numbers, and the Intel and AMD ones aren't exactly the same from a supporting components point of view. Nevertheless:

Complete peak system power consumption at the wall:

Intel 8380 (40C80T) x2 - 863.9W
Intel 8280 (28C56T) x2 - 649.6W

AMD 7713 (64C128T) x2 - 656.1W
AMD 75F3 (32C64T) x2 - 817.0W (high-frequency parts)

That's 10.79w per core for the dual 8380, a decrease of 7.4% from dual 8280s pulling 11.59w per core which is a marginal improvement but providing a ~40% aggregate performance increase but with a 40% increase in core/thread count soooo....?

Frankly, Ice Lake looks like just bigger Skylake when boiled down to numbers like that, very disappointing.
