Intel Core i7-9700K 9th Gen CPU Review: Eight Cores And No Hyper-Threading
Great balance between price and performance
Why you can trust Tom's Hardware
VRMark, 3DMark
We aren't big fans of using synthetic benchmarks to measure performance, but 3DMark's DX11 and DX12 CPU tests provide useful insight into the amount of horsepower available to game engines.
Core i7-9700K's eight physical cores can't keep up with Ryzen 7 2700X during the DX12 and DX11 CPU benchmarks. Even overclocked to 5.1 GHz, Intel's chip lands behind the 4.2 GHz Ryzen.
In the DX12 test, Core i7-9700K offers a nice step forward from its predecessor, the Core i7-8700K. That's despite losing Hyper-Threading Technology. As we can see, though, Ryzen's implementation of simultaneous multi-threading serves up a bit more performance.
UL's VRMark test lets you gauge your system's suitability for use with the HTC Vive or Oculus Rift, even if you don't currently own an HMD. UL defines a passing score as anything above 109 FPS. Core i7-9700K posts a surprisingly strong frame rate, beating the overclocked -9900K. Our interpretation is that this benchmark runs best on physical cores, rather than getting split off onto logical processors.
Ashes of the Singularity: Escalation
Ashes of the Singularity: Escalation is a computationally intense title that scales well with thread count. The stock -9700K and Ryzen 7 2700X essentially tie during the test, with the latter offering a slightly better 99th percentile score. As expected, given the i7-9700K's much higher overclocking headroom, Intel's processor pulls ahead after tuning.

rantoc Considering the amonth of security flaws that have been found lately the lack of HT could become a blessing in the end!Reply -
logainofhades I would like to see a locked at same clocks review, for these CPU's. It seems you really have to push Intel, to handily surpass AMD. It reminds me of the FX vs Sandy bridge days.Reply -
ingtar33 Well I just went from an I5-4690K to an AMD Ryzen 7 2700 after seeing the price of intel's current lineup, and knowing that Ryzen2 is coming in another 6mo or so. Personally I thought it was a no brainer, since the 7 2700 could be had for $260, mine is in an mitx build right now with a little Kracken M22 cooling it, and as I type on it it's currently plugging along at 4.2 ghz with DDR4 3600 ram in it.Reply
What point am I making? Well, the motherboard, cpu cooler and cpu combined were cheaper then this i7 in this review. chew on that. And remember that ryzen2 should be out sometime in the spring of 2019, and it will be completely compatible with everything I just purchased while being on par with or even faster then this last intel chip.
Now that you've chewed on that for a bit, ask yourself "why did THG stamp an editor approval on this chip again?" We probably should, "Just buy it," I guess, and not ask so many questions. -

except that's not what we're seeing. 105.5 fps vs 94.9 fps is 10.4%, a 10.4% improvement for the 8c16t intel core i9-9900k. yet the chip is running at 5.0ghz vs the 8c16t ryzen 7 2700x at 4.2 ghz, which means the intel is clocked about 19.0% faster then the AMD to get a 10.4% lead in FPS.
These Intel cpus DO NOT have higher IPS then Ryzen. If anything, assuming there isn't some sort of scaling issue in the testing suite, this seems to indicate that intel's cpus have moderately less IPS then AMD Ryzen+ and are currently getting by with clock speed alone. Which means this is as far away from sandy bridge vs fx then we could get. Sandy bridge didn't just clock to 5ghz, but was sporting almost 40% better IPS then Piledriver FX cpus. -

You are getting product and code names confused. Ryzen 2 (Zen+) has been out for over six months already and your new Ryzen 2700 is one of those. Ryzen 3 (Zen 2) is what's coming out in 2019 on 7nm.21463471 said:And remember that ryzen2 should be out sometime in the spring of 2019 -

It to be proven actuate by doing a math equation. 99.99% of the internet making claims with no source to back it up. -

This only works if you don't know CPU and GPU utilization.
Looking at a lot of gaming benchmarks even the i3/pentiums/2400g etc are only 10-20% below the 9900k because gaming benchmarks are made to push the GPUs and not the CPUs so the GPUs bottleneck way before the CPUs,and even if they don't, scaling in games means that slower CPUs can just use more threads to get to the same FPS.
Look at CPU benchmarks the deficit the ryzen CPUs have there is still there in gaming it just shows in the utilization where the ryzen cpu will have 30-40% more utilization (2700x vs 9900k) . -
Dantte PCgamers did some testing delidding a 9900K and determined that the solder TIM does NOT provide any additional cooling when compared to a 8700K because the die is much thicker (about 32% thicker) and hampers the transfer. Also the solder is too thick as well.Reply
They tested and proved this theory by delidding and replacing the solder with conductonaut and got a 8C decrease in temps. Then they lapped the die -.15 and -.20mm and retested which came back with even lower results. -
t99 Glad I went with a 2600 for only 150$ new and just OC if needed. Basically a 2600x and the avg is within 20% of an OC'd 9900k and 10% of 8600k.Reply
When you account for the difference in cooling and motherboards as well you can get a 2600 + 1070ti for price of a 9700k.
Maybe we will see larger gaps with the new intel when they test 1080p on a 2080. So glad I didnt wait and go with one of these
