Intel's Xeon Cascade Lake vs. NVIDIA Turing: An Analysis in AI

[harlan4096]

It seems like the new motto for Silicon Valley for the last few years has been “Data is the new oil,” and for good reason. The number of companies employing machine learning-based AI technologies has exploded, and even a few years after all of this has kicked off in earnest, those numbers continue to grow. This form of AI is no longer just an academic thesis or curious research project, but instead machine learning has become an important part of the enterprise market, and the impact on enterprise hardware – both purchasing and development – would be difficult to overstate. This is the era of AI.

At first sight, the hardware choices for these kinds of applications seem simple: Intel Xeon CPUs for storing and preprocessing data, NVIDIA GPUs for (almost) everything AI. And indeed, this has largely been case for the last few years now. However, NVIDIA’s competitors have not been standing idly by the entire time – and that especially goes for Intel, whose enterprise market share all of this ultimately threatens. With everything from dedicated low-power inference processors to purpose-optimized Xeons, Intel is taking aim at every level of the AI market. The net result is that between all of these competitors, we’re seeing AI tackled from many different directions, and the hardware battle for AI era is insanely interesting in our humble opinion.

Today we’re taking a look at what’s perhaps the heart of Intel’s hardware in the AI space, Intel’s second-generation Xeon Scalable processors, better known as "Cascade Lake". Introduced a bit earlier this year, these new processors are still based on the same core Skylake architecture as the first-generation products, but incorporate a number of new instructions to speed up AI performance.

And as far as new technology goes, this is certainly the most interesting aspect of Cascade Lake. While we could talk about the three to six percent general CPU performance improvement, the 56 cores of Intel’s most expensive processor ever, and the "world record benchmarks," these small improvements are close to irrelevant for the near and mid-term future of the IT world. Just look at the very first slide of the Intel press & analyst briefing.
