Exclusive: Testing Intel's Unreleased Core i9-9900KS

Core i9-9900KS Web Browser and Encoding Performance

We include stock testing results of the Core i9-9900KS with both our custom loop (CL) and Corsair H115i cooler (H115i).

Browsers tend to be impacted more by the recent security mitigations than other types of applications, so Intel has taken a haircut in these benchmarks of fully-patched systems.

The ARES-6 web browser benchmark focuses on the latest and greatest JavaScript features, with a heavy focus on forward neural networks used for machine learning tasks, and browser responsiveness.  Here the Core i9-9900KS leverages its single-threaded prowess to take the lead, and we see a similar pattern with the other browser workloads.

The SVT-AV1 encoder is an Intel- and Netflix-designed software video encoder that became available earlier this year. This new encoder is more scalable than other encoders, thus offering faster performance paired with efficient compression. While it may seem counterintuitive to use an Intel-designed encoder for testing AMD processors, consider that most encoders are inherently reliant upon per-core performance, which is a strength of Intel, while SVT-AV1 exposes the power of threading, a strength of Ryzen. At stock settings, the Ryzen 9 3900X dominates the test pool, but the auto-overclocking PBO feature does little to improve performance. We see expected gains from the -9900KS after overclocking, and the Core i9-9900K with tuned memory shows that memory data transfer rates have an impact on this test. 

Our LAME and FLAC tests, like many encoders, rely heavily upon per-core performance. That means Intel's frequency advantage confers a big lead. 

Intel processors traditionally leverage high frequencies to dominate the HandBrake x265 test, which relies heavily on AVX instructions, and the x264 test. But Intel's higher clock speed isn't too much of an advantage in these tests when the competition has twice the number of threads.

    AMD 3900X is not a 14nm CPU. Guess that is a typo, should be 7 nm.

    Yet another super underwhelming Intel release. I guess they'll up their game next gen, but at the price they're asking for it, it's at best "meh".

    There's almost zero reason to buy this CPU if the rumored price is accurate. It's only for those who want the absolute best gaming experience. For almost every other usage case in the $500 price bracket, the 3900X is the clear winner.

    I still find it funny that AMD's 12 core CPU consumes less power than Intel's 8-core. My how the times have changed...

    Considering the clock speed difference and that while its not quite 7nm it is still a smaller node than Intels 14nm its not surprising at all. If anything its to be expected. If Intel was using less power with a massive clock speed advantage on a larger process then something would be wrong.

    I totally agree. 7nm especially has been a huge advantage on that front. It's just that AMD CPUs have traditionally been power hogs while Intel has been fast and power efficient. I find it funny that the roles are somewhat reversed now.

    "Power hog" is relative - at the time of the Athlon XP, the Pentium 4 had a secondary role as a room heater.

    The advertised TDP is still a joke on these heaters...

    9900K @5Ghz performs better than 9900KS @5GHz and costs lesser ? OMG! I understand there are bug fixes, but the cost increase for very little performance increase, that too at 5.2GHz OC is not worth it IMHO. For the price of this CPU, I can get the 3700X/Mobo/16GB ram and it does not make a lot of difference at 1440P anyway.

    is it possible to have Paul also test these new chips with mitigation on how they affect PCIe SSD performance?

    Another typo is the 49.95 per thread price for the 3900X. 499/24=49.95?? The whole point of this was to try and act like Intel was releasing a competitive product, but they are just pulling the same stuff as when they did the 8086K. A special bin for <2% increase and more $$
