The usage is mostly video editing, gaming and others desktop usage. Is the xeon platinum will really use all the cores under windows 10 in real life. Someone tested it side by side to see if the xeon perform faster or not ?
The Xeon 8176 will be noticeably slower during everyday tasks and especially gaming. It will crush all when it comes to video encoding though. Its REALLY more of a server encoding CPU, than one you'd want to use for daily tasks.
As for using an ES processor don't, they are technically stolen property from Intel, many times they do not perform as expected, and we do not support them here.
If money is no object you'd be better off building a Ryzen Threadripper 2950 or 2990, they perform WAY better in all aspects overall and the 1% lows are nominal enough. You also might consider waiting and going with a Ryzen 3000 series processor.
