The Intel Celeron 4305U was a mobile processor with 2 cores, launched in April 2019, at an MSRP of $107. It is part of the Celeron lineup, using the Whiskey Lake architecture with BGA 1528. Celeron 4305U has 2 MB of L3 cache and operates at 2.2 GHz. Intel is making the Celeron 4305U on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Celeron 4305U, which limits its overclocking potential.
With a TDP of 15 W, the Celeron 4305U 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 machine, Celeron 4305U uses a PCI-Express Gen 3 connection. This processor features the UHD Graphics 620 integrated graphics solution.
Hardware virtualization is available on the Celeron 4305U, 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) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
