Intel unveils its 288-core Leviathan 5th-gen Xeon CPU, but if anything about reports are true then we just could see an even bigger beast on the horizon. Just so you know, there are 144, 288, and many more cores on the horizon, but you should also remember that they are all single-threaded.
Intel 288-Core Leviathan 5th-Gen Xeon CPU
The CEO of Intel has just pulled the plug on a new Xeon Scalable “Sierra Forrest” processor that is still yet to be named. The “Emerald Rapids” part as you should know is a 5th-generation model with 288 efficient or E-cores as well as 288 threads, which is a very clear attempt in trying to capitalize on cloud-native workloads that hyperscalers are so very fond of.
The press release of the company states that the part in question will deliver 2.5x better rack density and 2.5x higher performance per watt in contrast to the 4th generation Intel Xeon. And that in question is inclusive of the 288-core model.
AMD (128-core), Amazon (64-core), Ampere (192-core) as well as others are also paying focus on single-core, single-thread products but have lower core counts when compared to the new product from Intel.
Expert Analysis of the New Development
Paul Alcorn from Tomshardware with this new development reckons that Intel is making use of two chiplets, with each containing 144 E-cores, but however, posits that Intel could add a third chiplet thus pushing the total core count to a staggering 432 cores. In contrast, the Xeon Phi 7295, which is the last attempt of Intel at manycore products, reportedly topped 72 cores and 288 threads.
Such a large amount of cores tightly bundled together generates its very own set of problems which may amount to power consumption and dissipation, memory bandwidth, cache coherence, clock speed and so many more. What we do know here is that this new Xeon is built making use of the new Intel 3 manufacturing process alongside the Intel 7 one.
The Direction of the Cloud Computing Market
The cloud computing market as you should know is gearing towards a gamut of products that offer a combination of more powerful as well as less powerful cores. Arm reportedly brought this paradigm that it then coined the big.LITTLE concept over a decade ago and it is only just recently that this paradigm got to move into the data center as well as desktop due to growing concerns regarding energy consumption and higher-density computing.
AMD and Intel Targeting the Same Audience
AMD and Intel made use of different ways to target the same audience. Intel however went arm’s way with two entirely different cores while AMD on the other hand developed a slightly different version of its already existing Zen-4-based core, which is in question differentiated only by marginal changes (cache, I/O). The launch of its Siena EPYC 8004 processor which happened yesterday points in that direction.
