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.
