The specifications of the Rocket Lake Xeon W-1300 Desktop CPUs from Intel have been leaked out; these CPUs will be aimed at mainstream workstation platforms. The details were disclosed at the ASRock Support list, which was discovered by Komachi.
It seems that Intel is working on at least five Rocket Lake Xeon W-1300 desktop CPUs. All these processors will be getting a branding of Xeon parts and aimed at W480 workstation motherboards while offering limited support on Z490 and H470 motherboards with BETA BIOS. Let’s take a look at the specifications of these parts.
At the top, we have Intel Xeon W-1390 (B0), an 8 core and 16 threads and 16 MB of L3 cache. The CPU offers a base clock of 2.80 GHz and a TDP of 80W. The Xeon-1390T (B0) features a TDP of 35W and has a base clock of 1.50 GHz, while the other specifications are the same as the standard offering.
The next one is Xeon W-1370 (B0) which features the same core configuration of 8 core and 16 threads. The Intel Rocket Lake workstation CPU offers 16 MB of L3 cache but has a base speed of 2.90 GHz with a TDP of 80W. There will definitely be T and P flavours of this chip that is not listed on the support page.
The last one, we have Intel Xeon W-1350P, which will offer 6 cores and 12 threads. The CPU will feature a base clock of 4.0 GHz and 125W TDP and 12 MB of L3 cache. The P variants offer high-end performance within the workstation family and also offer much higher clock speeds.
The standard 80W variant of the same chip offers a base clock of 3.30 GHz. Intel will launch its Rocket Lake 11th Gen Desktop CPU family on 30th March; then, it can be expected that the Xeon parts will come in April 2021 along with the W480 based motherboards.
