Cascade Lake Processors

Cascade Lake Processors

August 25, 2019

Intel’s latest Xeon line (Cascade Lake) were released in Q2’19. These processors are socket compatible with the previous generation (Skylake), but may require a BIOS update on existing LGA3647 motherboards for support. The main improvements over the previous generation are:

  • Increased CPU core counts, clock speeds, and L3 cache
  • Support for DDR4-2933 memory
  • Introduction of the new AVX-512 VNNI instruction for Deep Learning
  • Enhanced Spectre and Meltdown Mitigations

 

Available SKUs

Intel has announced 58 SKUs ranging from 6 to 56 cores and $213 to $13,000+ (MSRP). The 28 general-purpose SKUs are listed below:

Conclusion

The Cascade Lake line of processors increases the core count, clock speeds, L3 cache, at a similar price point to the previous generation, Skylake. If you’re considering purchasing a Xeon processor, we recommend using this latest generation. The CPUs are only a portion of your server selection; RAM, GPUs, storage, networking, chassis, MB, etc. should also be considered.
