Hi Roger hope you are well!! Here I am running Window7 64Bit how can I find the CPU details which shows how many cores I know it is an AMD CPU whatever that is. Thank you Roger Serge VE1KG

They don't support AVX, of course. They are old but since they have up until now been (barely/marginally) OK in terms of speed and CPU utilization even with Windows 10 I haven't replaced them before now. All each of them does is run an SDR program, WSJT-X, and Dimension-4. If WSJT-X added performance enhancements that would only work with a newer CPU, that would probably push me to upgrade them. I had been considering doing that anyway, as they have slowed enough with Windows 10 and each of its major updates that I suspect they won't be "OK" for my purposes for much longer, as each major Windows update slows them further. So if I need to get new computers to get the most out of a future version of WSJT-X, I will thank you for pushing me to do what I should have already done by now. From my perspective, I would say don't spend any time just to keep my ancient Core 2 Duos running with WSJT-X. Getting 13 years out of a CPU/motherboard is plenty :) Thanks for polling the group on this and for all that you do, and 73, Roger W3SZ On 6/8/2021 07:38 PM, Bill Somerville wrote: > Hi all WSJT-X users, > > we are looking into some performance enhancements that will take > advantage of some parallel processing features of modern CPU > architectures.
