Intel's Core i9-9900K: Technically The Highest Performing Gaming CPU
When Intel announced the new processor lineup, it billed the Core i9-9900K as the ‘world’s best gaming processor’. Here’s Intel’s Anand Srivatsa, showcasing the new packaging for this eight core, sixteen thread, 5.0 GHz giant:
In actual fact, the packaging is very small. Intel didn’t supply us with this upgraded retail version of the box, but we were sampled with a toasty Core i9-9900K inside. We sourced the i7-9700K and i5-9600K from Intel’s partners for this review.
With the claim of ‘world’s best ever gaming processor’, it was clear that this needed to be put to the test. Intel commissioned (paid for) a report into the processor performance by a third party in order to obtain data, which unfortunately had numerous issues, particularly with how the chips it was tested against were benchmarked, but here at AnandTech we’ll give you the right numbers.
For our gaming tests this time around, we put each game through four different resolutions and scenarios, labelled IGP (for 720p), Low (for 1080p), Medium (for 1440p to 4K), and High (for 4K and above). Here’s a brief summary of results:
- World of Tanks: Best CPU at IGP, Low, Medium, and top class in High
- Final Fantasy XV: Best CPU or near top in all
- Shadow of War: Best CPU or near top in all
- Civilization VI: Best CPU at IGP, a bit behind at 4K, top class at 8K/16K
- Ashes Classic: Best CPU at IGP, Low, top class at Medium, mid-pack at 4K
- Strange Brigade DX12/Vulkan: Best CPU or near top in all
- Grand Theft Auto V: Best CPU or near top in all
- Far Cry 5: Best CPU or near top in all
- Shadow of the Tomb Raider: Near top in all
- F1 2018: Best CPU or near top in all
There’s no way around it, in almost every scenario it was either top or within variance of being the best processor in every test (except Ashes at 4K). Intel has built the world’s best gaming processor (again).
On our CPU tests, the i9-9900K hit a lot of the synthetics higher than any other mainstream processor. In some of our real world tests, such as application loading or web performance, it lost out from time to time to the i7 and i5 due to having hyper-threading, as those tests tend to prefer threads that have access to the full core resources. For memory limited tests, the high-end desktop platforms provide a better alternative.
While there’s no specific innovation in the processors driving the performance, Intel re-checked the box for STIM, last used on the mainstream in Sandy Bridge. The STIM implementation has enabled Intel to push the frequency of these parts. It was always one of the tools the company had in its back pocket, and many will speculate as to the reasons why it used that tool at this point in time.
But overall, due to the frequency push and the core push, the three new 9th Generation processors sit at the top of most of our mixed workload tests, given the high natural frequency, and set a new standard in Intel’s portfolio for being a jack of all trades. If a user has a variable workload, and wants to squeeze performance, then these new processors will should get you there.
So now, if you are the money-no-object kind of gamer, this is the processor for you. But it’s not a processor for everyone, and that comes down to cost and competition.
At $488 SEP, plus a bit more for 'on-shelf price', plus add $80-$120 for a decent cooler or $200 for a custom loop, it’s going to be out of the range for almost all builds south of $1500 where GPU matters the most. When Intel’s own i5-9600K is under half the cost with only two fewer cores, or AMD’s R7 2700X is very competitive in almost every test, while they might not be the best, they’re more cost-effective.
The outlandish flash of the cash goes on the Core i9-9900K. The smart money ends up on the 9700K, 9600K, or the 2700X. For the select few, money is no object. For the rest of us, especially when gaming at 1440p and higher settings where the GPU is the bigger bottleneck, there are plenty of processors that do just fine, and are a bit lighter on the power bill in the process.
Edit: We initially posted this review with data taken with an ASRock Z370 motherboard. After inspection, we discovered that the motherboard used intentionally over-volts 9th Generation Core processors in our power testing. While benchmarking seems unaffected, we have redone power numbers using an MSI MPG Z390 Gaming Edge AC motherboard, and updated the review accordingly.

TSMC will do the job for AMD, and in March/April, we should be seeing AMD release the 3700X and/or 3800X that will be hitting the same clock speeds as the 9900k, but with a better IPC.BurntMyBacon - Friday, October 19, 2018 - link
I am certainly happy that AMD regained competitiveness. I grabbed an R7 1700X early on for thread heavy tasks while retaining use of my i7-6700K in a gaming PC. That said, I can't credit them with everything good that comes out of Intel. To say that Intel would not have released an 8 core processor without AMD is probably inaccurate. They haven't released a new architecture since Skylake and they are still on a 14nm class process. They had to come up with some reason for customers to buy new processors rather than sit on older models. Clock speeds kinda worked for Kaby Lake, but they need more for Coffee Lake. Small, fixed function add-ons that only affect a small portion of the market probably weren't enough. A six core chip on the mainstream platform may have been inevitable. Going yet another round without a major architecture update or new process node, it is entirely possible that the 8-core processor on the mainstream platform was also inevitable. I give AMD credit for speeding up the release schedule, though.As to claims that the GF manufacturing is responsible for the entire 1GHz+ frequency deficit, that is only partially true. It is very likely that some inferior characteristics of the node are reducing the potential maximum frequency achievable. However, much of the limitations on frequency also depends on how AMD layed out the nodes. More capacitance on a node makes switching slower. More logic between flip-flops require more switches to resolve before the final result is presented to the flip-flops. There is a trade-off between the number of buffers you can put on a transmission line as reducing input to output capacitance ratios will speed up individual switch speeds, but they will also increase the number of switches that need to occur. Adding more flip-flops increases the depth of the pipeline (think pentium 4) and increases the penalty for branch misses as well as making clock distribution more complicated. These are just a few of the most basic design considerations that can affect maximum attainable frequency that AMD can control.
Consequently, there is no guarantee that AMD will be able to match Intel's clock speeds even on TSMC's 7nm process. Also, given that AMD's current IPC is more similar to Haswell and still behind Skylake, it is not certain that they next processors will have better IPC than Intel either. I very much hope one or the other ends up true, but unrealistic expectations won't help the situation. I'd rather be pleasantly surprised than disappointed. As such, I expect that AMD will remain competitive. I expect that they will close the gaming performance gap until Intel releases a new architecture. I expect that regardless of how AMD's 7nm processors stack against Intel's best performance-wise, I expect that AMD likely bring better value at least until Intel gets their 10nm node fully online.

"To say that Intel would not have released an 8 core processor without AMD is probably inaccurate."It's technically inaccurate to say they would have never made any kind of 8-core processor, sure, but nobody's saying that. That's a straw man. What they are saying is that Intel showed no signs whatsoever of being willing to do it until Ryzen landed at their doorstep.
To be clear, the evidence is years of Intel making physically smaller and smaller quad-core chips for the mainstream market and pocketing the profit margins, followed by a sudden and hastily-rescheduled grab for the "HEDT" desktop market the second Ryzen came out, followed by a rapid succession of "new" CPU lines with ever-increasing core counts.
You're also wrong about AMD's IPC, which is very clearly ahead of Haswell. The evidence is here in this very article where you can see the difference in performance between AMD and Intel is mostly a function of the clock speeds they attain. Ryzen was already above Haswell for the 1000 series (more like Broadwell) and the 2000 series brought surprisingly significant steps.

" What they are saying is that Intel showed no signs whatsoever of being willing to do it until Ryzen landed at their doorstep."Intel released an 8 core what? 3 years before Ryzen. Sure, it was one of their super expensive Extreme procs, but they still did it. They were slowly ramping up cores for the HEDT market, while slowly bringing them to more normal consumer prices. 3 years before Ryzen, you could get a 6 core i7 for $400 or less. A year before that it was like $550-600. A 1-2 years before that, a 6 core would be $1000+. 8 cores were slowly coming.
What Ryzen did was speed up Intel's timeframe. They would have came and came at a price point that normal consumers would be purchasing them. If I had to guess, we're probably 2-3 years ahead of what Intel probably wanted to do.
Now would Ryzen exist, if not for Intel? Core for core, AMD has nothing that can compete with Intel. So...ramp up the core count. We really don't see Intel going away from a unified die design, so that's the best way AMD has to fight Intel. I'm personally surprised AMD didn't push their MCM design years ago. Maybe they didn't want to cannibalize Opteron sales, bad yields, I don't know. Must have been some reason.

Rofl, delusional poster is delusional. And anyone who bought a 2700X sure as shit doesn't need to do anything to "defend their purchase" to themselves hahaha.evernessince - Saturday, October 20, 2018 - link
Got on my level newb. The 9900K is a pittance compared to my Xeon 8176. I hope you realized that was sarcasm and how stupid it is to put people down for wanting value.JoeyJoJo123 - Friday, October 19, 2018 - link
>I think far too much emphasis has been placed on 'value'.Then buy the most expensive thing. There's no real need to read reviews at that point either. You just want the best, money is no object to you, and you don't care, cool. Just go down the line and put the most expensive part for each part of the PC build as you browse through Newegg/Amazon/whatever, and you'll have the best of the best.
For everyone else, where money is a fixed and limited resource, reading reviews MATTERS because we can't afford to buy into something that doesn't perform adequately for the cost investment.
So yes, Anandtech, keep making reviews to be value-oriented. The fools will be departed with their money either way, value-oriented review or not.

They'll be parted, yes - and we can hope for departed.GreenReaper - Saturday, October 20, 2018 - link
Don't be *too* harsh. They're paying the premium to cover lower-level chips which may be barely making back the cost of manufacturing, thus making them a good deal. (Of course, that also helps preserve the monopoly/duopoly by making it harder for others to break in...)Spunjji - Monday, October 22, 2018 - link
Yeah, to be honest the negatives of idiots buying overpriced "prestige" products tend to outweigh the "trickle down" positives for everyone else. See the product history of nVidia for the past 5 years for reference :/
