AMD today released the Ryzen Threadripper 1900X eight-core HEDT (high-end desktop) processor. This product is targeted at pro-sumers who could use the quad-channel memory bandwidth and added I/O which the Threadripper HEDT platform brings to the table, but can make do with 8 cores/16 threads, which is why the chip is priced just $50 higher than the 8-core/16-thread Ryzen 7 1800X, at USD $549. The Threadripper 1900X comes with higher clock speeds than the 1800X, with 3.80 GHz nominal clock-speed (compared to 3.60 GHz of the 1800X), 4.00 GHz boost, and XFR adding another 200 MHz to the boost clock, if your cooling is good enough.The Ryzen Threadripper 1900X gives you the full quad-channel DDR4-3200 memory interface, with support for up to 2 TB memory, and ECC support. There's even unofficial RDIMM support. The chip also offers the full 64-lane PCI-Express interface, with the same PCI-Express device configurations as the higher 1920X and 1950X parts. AMD created the 1900X by disabling two cores per CCX in each of the active 8-core dies on the Threadripper MCM. The chip also only features 16 MB of L3 cache, that's 4 MB per active CCX. Its TDP continues to be rated at 180W. AMD put out its internal testing performance numbers for the 1900X.AMD's performance slides follow.
