It has a base frequency of 350MHz which can go up to 1GHz as well as offering DirectX 12 support. It integrates Intel UHD Graphics 630 on board. It is on par with competitor processors.Īmong its many features, Intel Enhanced Speedstep, Turbo Boost 2.0 and Virtualization are activated. It has a maximum Thermal Power Design of 65W.

This processor also supports DDR4 based RAMs with maximum memory support of 64GB.

Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. It doesn't have an unlocked multiplier, therefore, it can't be overclocked using traditional methods. It offers 6 physical cores (6 logical), initially clocked at 2.8GHz, which may go up to 4.0GHz on a single core using Turbo Boost, or 3.5Ghz if all six cores are boosted. DPAT limits the settings for the processor to keep latency low all the time.The Core i5-8400 6-Core 2.8GHz is a high-end CPU based on Intel's 8th Gen 14nm, Coffee Lake microarchitecture. 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.
