The Intel Pentium Gold 5405U was a mobile processor with 2 cores, launched in January 2019, at an MSRP of $161. It is part of the Pentium Gold lineup, using the Whiskey Lake architecture with BGA 1528. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 4 threads. Pentium Gold 5405U has 2 MB of L3 cache and operates at 2.3 GHz. Intel is building the Pentium Gold 5405U on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Pentium Gold 5405U, which limits its overclocking capabilities. With a TDP of 15 W, the Pentium Gold 5405U consumes very little energy. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2133 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, Pentium Gold 5405U uses a PCI-Express Gen 3 connection. This processor features the UHD Graphics 620 integrated graphics solution. Hardware virtualization is available on the Pentium Gold 5405U, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
