896 vCPUs and 32TB RAM... I do not want to see the license cost for SQL Server on one of these! Doing some quick maths: 2vCPUs = 1 Core (give or take) so I think these are 8 x 56 Core Xeons... SQL Enterprise (needed to use the 32TB of RAM fully) is around 7K per core, so the license for SQL alone would be $3.13 Million... It looks like Windows Server 2022 Datacenter is another 6.1K per core, so $2.75 million for that... $6 Million for licencing on SQL and Windows alone... And at $407.68 for the base rate (PAYG) it's another $3.4 Million for the hardware per year...

As far back as 2011, I was reading articles from this blog: <a href="https:&#x2F;&#x2F;www.1024cores.net&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.1024cores.net&#x2F;</a><p>I remember thinking: &quot;That&#x27;s crazy! One kilo-cores! They&#x27;re processors, not memory!&quot;<p>Then, almost immediately, it started sinking in that <i>this</i> is what Moore&#x27;s law means. That yes, sooner or later, I&#x27;ll be working on a single system with more than a thousand cores (or hardware threads) in it.<p>This behemoth of a server probably has 8 sockets and I&#x27;m guessing it is the size of half a rack or thereabouts.<p>An upcoming AMD EPYC processor is rumored to have 256 cores (512 threads), which means that a &quot;normal sized&quot; server will have 512c&#x2F;1024t soon at a more reasonable cost: <a href="https:&#x2F;&#x2F;www.extremetech.com&#x2F;computing&#x2F;328692-future-256-core-amd-epyc-cpu-might-sport-remarkably-low-600w-tdp" rel="nofollow">https:&#x2F;&#x2F;www.extremetech.com&#x2F;computing&#x2F;328692-future-256-core...</a><p>Similarly, Intel is planning a processor with 288 cores within a year, although it may or may not have hyper-threading: <a href="https:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;21276&#x2F;intel-previews-sierra-forest-with-288-e-cores-announces-granite-rapids-d-for-2025-launch-at-mwc-2024" rel="nofollow">https:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;21276&#x2F;intel-previews-sierra-f...</a><p>A challenge I like to pose to software developers is this: If you were given one of these servers, and you could install your software on it, would it get 100x faster for <i>one</i> user than a server with just 10 vCPUs?
