The Intel Core i9-9900T was a desktop processor with 8 cores, launched in April 2019, at an MSRP of $423. It is part of the Core i9 lineup, using the Coffee Lake Refresh architecture with Socket 1151. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. Core i9-9900T has 16 MB of L3 cache and operates at 2.1 GHz by default, but can boost up to 4.4 GHz, depending on the workload. Intel is building the Core i9-9900T on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Core i9-9900T, which limits its overclocking capabilities. With a TDP of 35 W, the Core i9-9900T consumes only little energy. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2666 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, Core i9-9900T uses a PCI-Express Gen 3 connection. This processor features the UHD Graphics 630 integrated graphics solution. Hardware virtualization is available on the Core i9-9900T, 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.
