Intel Xeon W-1300 series “Rocket Lake” processor lineup announced

Intel has quietly announced the details of its latest generation of XEON W series workstation processors using 14nm “Rocket Lake” chips. These chips use the same Socket LGA 1200 package as the 11th-generation Core desktop processors but are compatible with the W580 chipset. The lineup includes two 6-core/12-thread and five 8-core/16-thread products.

The leader is XEON W-1390P with a clock speed of 5.30 GHz, followed by W-1390 with 5.20 GHz. These two SKUs have a Thermal Velocity Boost (TVB) function, similar to the 11th generation Core i9 series. Because each CPU is cut on a different location on a wafer, the performance of each core will be different. Thermal Velocity Boost was born in consideration of this problem. It first appeared on the tenth-generation Core i9 and i7. It is a self-corresponding overclocking acceleration technology that will trigger when the CPU temperature is below 70°C. This feature accelerates the two strongest cores to 5.3GHz.

Next are XEON W-1370P and W-1370, with clock frequencies of 5.20 GHz and 5.10 GHz, respectively. These products do not have the previously mentioned TVB boost function and are equivalent to the 11th generation Core i7 SKU in many respects.

The slowest of these 8-core products is the energy-saving version of W-1390T, with a clock of only 1.50 GHz and a maximum boost frequency of 4.90 GHz, but the TDP is only 35W. Among other SKUs, the rated TDP of the SKU with P-series is 125W, while the rated TDP of the non-P series is 80W. All XEON W processors support 128GB dual-channel DDR4-3200 memory and support ECC.
