Intel Core i9-9900KS Ships in Oct., Cascade Lake-X Nearly Doubles Performance Per Dollar
Intel made some product announcements at a pre-IFA event in Berlin this week, including news on the Core i9-9900KS that it announced earlier this summer and an upcoming product refresh for its Core X family. Intel has been pushed onto its proverbial heels by AMD’s 7nm onslaught, and it has yet to respond to those products in a significant way. These new parts should help do that, albeit at the high end of the market.
First, there’s the Core i9-9900KS. This CPU is a specially-binned Core i9-9900K, with the ability to hit 5GHz on all eight CPU cores, and a 4GHz base clock. That’s a 1.1x improvement over base clock on the 9900K, but the impact of the all-core 5GHz boost is harder to estimate. A sustained all-core 5GHz clock speed would be substantially higher than the Core i9-9900K we have here at ET — but Intel CPUs no longer hold their full clocks under sustained load. Our Core i9-9900K will turbo up to high clocks for 20-30 seconds, depending on the workload, before falling back to speeds in the lower 4GHz range when run on our Asus Z390 motherboard.
A faster Core i9 will undoubtedly improve Intel’s positioning against the Ryzen 7 and Ryzen 9 family, but even a chip that could hold an all-core 5GHz boost won’t catch the 12-core/24-thread Ryzen 9 3900X in most multi-threaded applications that can scale up to 12 cores. The gap between the two parts is too large to be closed in such a manner.
What the 9900KS will do for Intel, however, is give it a little more room to maneuver in gaming performance, which is where the company is making its stand. On the desktop side of things, Intel is facing a genuinely tough competitive situation, and even the advent of 10-core desktop CPUs may not solve the problem.
Cascade Lake May Meaningfully Respond to Threadripper
For the past two years, AMD has hammered Intel with high-performing, (relatively) low-cost workstation processors. Even though Intel’s Skylake X CPUs have often punched above their weight class compared with the Core family, AMD’s willingness to shove tons of cores into its chips has secured it the lead as far as performance/dollar, as well as the absolute performance lead in many well-threaded applications.
Intel may intend to challenge this in a far more serious way this year. The company showed the following slide at IFA:
The implication of this slide is that Intel will launch new Cascade X CPUs at substantially lower per-core prices than it has previously offered. We say “implication,” however, because technically this is a slide of performance per dollar, not price. Imagine two hypothetical CPUs, one with a price of $1,000 and performance of 1x, while the other chip costs $1,500 and has 2x the performance of the first chip. The second chip is 1.5x more expensive than the first but offers 1.33x more performance/dollar.
With AMD potentially eyeing Threadripper CPUs with up to 64 cores, however, Intel may not feel it has a choice. We haven’t heard from AMD on this point yet, so much is up in the air. There seems to be a battle brewing in these segments — hopefully, Intel will bring a much more price-competitive series of parts to market.
