Intel Cascade Lake AP, E-2100 processors launched

Cascade Lake also debuts Intel Optane DC persistent memory and implements hardware security mitigation to address Spectre and Meltdown vulnerabilities.

Intel says that Cascade Lake processors will be arranged in multi-chip packages with CPUs that offer up to 48 cores per socket. That's a doubling over Skylake, and 50 percent more than what we've seen so far from AMD with Eypc or Marvell with its Cavium ThunderX Arm offering. Details of how Intel will connect the MCMs together or how many cores are in each chiplet - that's the sort of detail we don't have yet. The flagship Xeon E-2186G ($450) is a hexa-core processor with HyperThreading enabled (12 threads), 12MB SmartCache, Intel UHD Graphics 630, a base clock of 3.8GHz and a Turbo Boost 2.0 clock of 4.7GHz. Intel didn't note whether Hyper-Threading would be available from Cascade Lake-AP chips, and indeed, its comparative numbers against that dual-socket Epyc 7601 system were obtained with SMT off on the AMD platform. By utilizing UPI for the interconnect, Intel claims their MCP design will provide performance consistency not found in other solutions.

"When it launches, we expect Cascade Lake Advanced Performance to be the world's fastest CPU, based on our current understanding of the Linpack performance of general processors commercially available in 2019", Intel stated in press materials. Intel didn't disclose the memory speed it used to arrive at this figure, however.

With its new DL Boost feature, Intel is promising a step-function improvement for deep learning inference moving to Cascade Lake-AP. Cascade Lake-AP takes that to a 17x, according to Intel.

After taking a little over a year to think on it, Intel appears to have decided that glue can be pretty Epyc after all. VNNI allows Cascade Lake processors to perform INT8 and INT16 operations that are important to AI inferencing operations.

More details on the entire Cascade Lake family, including Cascade Lake AP, are set to come at next week's Supercomputing conference, so stay tuned for more information as it becomes available!

The company has also revealed additional details on Cascade Lake, which it has itself framed as a direct competitor to rival AMD's Epyc processor family.

On this somewhat skewed playing field, Intel 'projects' that Cascade Lake will outperform AMD's Epyc 7601 by 3.4-fold in the Linpack benchmark and 1.3-fold in Stream Triad, while outperforming its own 28-core Intel Xeon Scalable 8180 by 1.21-fold and 1.83-fold respectively.
