Hi Bill, One of my older Lenovo X201 series does not support AVX (i5-520M). Newer ones do support (but not AVX2). 73, Reino OH3mA
PS. i3-370M that was mentioned seems not to support, but i7-2600 on the same page does. -----Alkuperäinen viesti----- Lähettäjä: Bill Somerville [mailto:g4...@classdesign.com] Lähetetty: 09 June 2021 02:38 Vastaanottaja: WSJT software development <wsjt-devel@lists.sourceforge.net> Aihe: [wsjt-devel] Call for information about PC systems being used for WSJT-X 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. In order to gauge how much backwards compatibility for older CPUs we will have to implement it would help to know who is using such older processors. Please don't turn this thread in to a mine is better than yours conversation, all I need to know is who or how many of you are using the older CPU architectures. Note that this applies to MS Windows, Intel Linux, and Intel macOS users, it is about CPUs not operating systems. The technology we will use is called AVX and that is present on all Intel CPUs branded Core i3/i5/i7/i9 (circa 2010 to present), it is also present on AMD CPUs since the Jaguar or Puma based CPU models (some late Athlon-II CPUs, all Zen based CPUs, including Ryzen) circa 2013 to present. Notably Intel CPUs branded Celeron, Pentium, or Atom do not support the AVX technology. So in summary, look up your CPU and if it **does not support AVX** (https://en.wikipedia.org/wiki/Advanced_Vector_Extensions) then let me know. 73 Bill G4WJS. _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
