AMD has released its third and cheapest Ryzen Threadripper CPU. The company officially launched the Ryzen Threadripper 1900X processor at a price of $549 (roughly Rs. 37,330).
The Threadripper 1900X has a 3.8GHz base clock, a 4GHz Turbo clock, and a 200MHz XFR range for short-term boosting if the CPU’s thermals and power consumption permit it. That’s not very different from the Ryzen 7 1800X, with its 3.6GHz base clock, 4GHz Turbo, and 100MHz XFR.
The larger changes are at the platform level, where the 1900X has 60 PCIe 3.0 lanes and a quad-channel DDR4 configuration compared with just 16 PCIe lanes and dual-channel RAM for the 1800X.
The I/O capabilities and PCI Express 3.0 lanes give the 1900X an edge over the 1800X, provided you’re running workloads that can take advantage of them. The 180W TDP is almost certainly a carry-over from the other Threadripper chips as opposed to a regularly encountered limit, though it’s possible that AMD calibrates the 1900X to stick to its upper clocks more aggressively than the 1800X. This, however, is speculation on our part.
AMD is aiming Threadripper at content creators, gamers and overclockers who want the best performance without spending too much. These CPUs are physically much larger than mainstream ones, and use a different socket called TR4 and are certified VR-ready. They support quad-channel DDR4 RAM and feature 64 lanes of PCIe bandwidth for high-speed components such as graphics cards and SSD arrays.
Because the Zen architecture is common between Ryzen product families, Threadripper CPUs are based on the same Infinity Fabric interconnect between internal clusters called Core Complexes, and have the same benefits including XFR which boosts speed beyond the rated limits when thermal conditions allow it, and SenseMI which adjusts operating parameters dynamically using hundreds of embedded sensors.
