Kris has touched on the many advantages of having a standard model. From what I am seeing with most people's use case scenario, only the GPU is what will determine what the machine is used for. IE: VR Research team may end up only needing a GPU upgrade.
Fortunately the new W-Series Xeon's seem to be equal or better to the Core i9's but with ECC support. So there's no sacrifice to performance in single threaded or multi-threaded workloads. With all that said, we'll move forward with the evaluation machine and find out for sure in real world testing. :) On Tue, Nov 7, 2017 at 12:30 PM, Kris Maglione <kmagli...@mozilla.com> wrote: > On Tue, Nov 07, 2017 at 03:07:55PM -0500, Jeff Muizelaar wrote: > >> On Mon, Nov 6, 2017 at 1:32 PM, Sophana "Soap" Aik <s...@mozilla.com> >> wrote: >> >>> Hi All, >>> >>> I'm in the middle of getting another evaluation machine with a 10-core >>> W-Series Xeon Processor (that is similar to the 7900X in terms of clock >>> speed and performance) but with ECC memory support. >>> >>> I'm trying to make sure this is a "one size fits all" machine as much as >>> possible. >>> >> >> What's the advantage of having a "one size fits all" machine?
