32 threads, 16 cores, and 77MB total cache “Fishhawk Falls” HEDT CPU leaked from Intel Sapphire Rapids

Share This Post

One of Intel’s upcoming high-end desktop (HEDT) CPUs based on the Intel Sapphire Rapids “Fishhawk Falls” series has leaked thanks to @momomo_us spotting an entry on the SiSoftware Sandra benchmark site. Termed the Intel Xeon W5-3433, the CPU looks like it will have 45 MB of L3 and 16 x 2 MB of L2 cache. Since there is 2 MB of L2 cache per core, it is reasonable to think that the part in question is a Sapphire Rapids workstation processor and not an Alder Lake SKU. According to the core configuration, the CPU looks to be a successor to the Intel Ice Lake-X Xeon W-3335 as it shares the same core count of 16 cores and 32 threads.

Intel Sapphire Rapids “Fishhawk Falls” HEDT CPU comes with 16 cores, 32 threads, and 77 MB of shared cache. Both datacenter and consumer SKUs are available in the Intel Sapphire Rapids series.

If a new Intel Xeon chip entry into the SiSoftware Sandra database turns out to be accurate, Intel may soon be updating its Xeon series of workstation CPUs. The future Intel Sapphire Rapids “Fishhawk Falls” series of consumer workstation CPUs appears to include the Intel Xeon W5-3433 noted in the database.


  • Sapphire Rapids Xeon CPUs are expected to take the fight to AMD’s EPYC Genoa in 2021. 10nm Intel Sapphire Rapids Xeon details emerge: dual-socket 96 core Xeon on the cards with PCIe 5.0 and DDR5 support but is it enough to take on 5nm AMD EPYC Genoa? 06/07/2020 I am Fawad, a fellow tech nerd. As a tech junkie, my relationship with technology goes back to my childhood years. Getting my first Intel Pentium 4 PC was the start of journey that would eventually bring me to Notebookcheck. Finally, I have been writing for tech media since 2018. From small no-name projects to industry leaders, I have worked with a number of tech publications.

  • Looking at the benchmark results, we see that the Intel Xeon W5-3433 scored 456.00 GOPS, a respectable number but nothing to write home about. As a comparison, AMD Ryzen Threadripper PRO 3955WX, another chip with 16 cores and 32 threads, scored 490.41 GOPS in the same test. This low score is to be expected since the Intel Xeon W5-3443 chip used here is only running at 1.99 GHz, a sign that the processor may have been an engineering sample.Codenamed “Fishhawk Falls”, Intel’s consumer-grade Sapphire Rapids HEDT CPUs were first rumored to launch in Q2 2022. VideoCardz speculates that, since Q2 is coming to a close and there is no launch in sight, the HEDT launch appears to have slipped further.
