ECC, ok, yes, spend money on that.<br>
But otherwise splurge for an NVMe SSD, long before spending $1 extra on the CPU.<br>

Adam's article actually c&p'ed the ryzen paragraphs from<br />other (game-centric) ryzen articles (or vice-versa?).<br /><br />However, none of the articles I read tell me what the upside is... they<br />just list the downside (latency). I assume AMD chose bandwidth over<br />latency, so one would hope the bw would be much higher on ryzen to<br />compensate for latency. Then your app will dictate whether ryzen or<br />xeon is better.<br /><br />As Adam said, one would hope AMD made this design decision on purpose,<br />rather than as a mistake. As a mistake, think lack of barrel shifter<br />on P4's. No one said chip designers are perfect... so I wouldn't be<br />too surprised either way.<br /><br />I stopped caring about that "last tiny bit of performance" about 10<br />years ago. If my next workstation is around 8X faster than my current<br />one for my workload, then I don't really care if it is actually 7X or<br />9X, as long as the price is semi-affordable. And I get ECC. And I get<br />a x16/x16 slot for discrete graphics.<br /><hr /><br />Roundtable mailing list<br />Roundtable@muug.ca<br /><a href="https://muug.ca/mailman/listinfo/roundtable">https://muug.ca/mailman/listinfo/roundtable</a><br /></pre></blockquote></div><br>
