Hi Ben,<br>
<br>
Thanks for your reply.<br>
<br>
I'd always assumed that Xeon's were faster because they had a<br>
different internal architecture to the Core range.  </blockquote><div><br></div><div>No, that would cost more.  The distinction between Xeon/i9/i7/i5 </div><div>is simply how well they test after manufacture.</div><div><br></div><div>Xeons were premium because there had to be less manufacturing errors to end up with larger caches.</div><div>But your i9 there has a larger cache, so maybe that quality dimension has shifted.</div><div>This is interesting reading...</div><div><div><a href="https://www.quora.com/How-does-Intel-design-and-produce-so-many-models-of-CPUs/answer/Jacob-VanWagoner?share=1&srid=tpqN">https://www.quora.com/How-does-Intel-design-and-produce-so-many-models-of-CPUs/answer/Jacob-VanWagoner?share=1&srid=tpqN</a></div><div></div></div><div><br></div><div>cheers -ben </div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I guess the heat<br>

Thanks again,<br>
