Thanks for sharing this question in the community. I will do my best to help you with this.
At this point I know that all Xeon processors support PrefetchW but I am in doubt with the Celeron you mentioned. I am going to check and I will be back with more information.
Sorry for the delay. I am still checking this information to provide accurate data. I will be back Soon.
Sorry for the delay on coming back to you.
Based on our research I can confirm that all Celeron processors currently listed on ARK page support PrefetchW. However; The E1200, E1400, E1500 and E1600 are the correct socket, but it will be necessary to check with your system manufacturer to verify if the motherboard support these processors.
