This report reveals, that other OEMs aren't much different neither. Send him the first of your links to report that it has been confirmed that such low performance is by design of the CPU and of the OEM (Dell). However, the user is complaining of super slow speeds.ĭon't know why the user is complaining. I have a user with a Dell Opens a new window that includes a Intel Core i7-8500Y CPU Opens a new window. If you have any suggestions, I'd be very grateful. I'll also include a screenshot from "Open Hardware Monitor" I'm unsure at this point what else to try to resolve the slow performance. Performed Windows "SFC Scan", "Check Disk", and "Disk Cleanup" operations.Intel Hyper-Threading, Intel SpeedStep Technology, Intel TurboBoost, Multi Core Support, C-States Support) Checked the XPS 13's BIOS "Performance" settings Opens a new window to make sure that it wasn't crippling the CPU (.Checked the "Power Options" to make sure the "Processor Power Management" was configured properly.Made sure BIOS and Intel drivers were up to date.He sent me a screenshot below that shows low clock speeds under a moderately high load (I also noticed that the kernel time graphs are out of sync, unsure what that means): However, the user is complaining of super slow speeds. DPAT limits the settings for the processor to keep latency low all the time.I have a user with a Dell Opens a new window that includes a Intel Core i7-8500Y CPU Opens a new window. Dell Processor Acceleration Technology (DPAT), enabled through the BIOS Dell Controlled Turbo, may provide a better performing solution than turning turbo off. Some environments such as High Frequency Trading in the Financial Markets need low latency in their transactions. There is some latency in stepping frequency, changing C states and other CPU functions. Turbo Boost is limited by the number of cores, current and estimated power consumption and temperature. When the OS instructs an Active core to enter C3 sleep state the other cores dynamically accelerate to a higher frequency. Turbo Boost is activated by the Operating System (OS) following ACPI standards using processor performance states. Intel Turbo Boost 2.0 provides the highest frequency of available cores in a multicore multiprocessor environment within the power constraints of the CPU. Dell Processor Acceleration Technology Summaryĭell servers set to Maximum Performance in the bios is intended for maximum throughput, not latency.
