Intel Core i7-9700K 9th Gen CPU Review: Eight Cores And No Hyper-Threading

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.

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.

INGTAR33, you can't just make up results and claim t
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) .

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.

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.

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.

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

So what? As long as the cpu isn't hitting 100% to do whatever you need it to do, be it gaming or streaming or both or something different, does it really make a hill of beans difference if a Ryzen is sitting at 60% and an intel at 50%?

Benchmarks are a tool, not gospel and 99% of all pc users couldn't tell, won't ever see any difference at all in anything they do. You'd need to be running both setups, side by side, running identical software, doing the same process and be using a digital timer. I see benchmarks where the 9900k does something in 2.3 seconds, the 2700x takes 2.6 seconds. Wow, really, the Intel is so much better, on a blown up graph.

Damn an OC'd 2600 (basically same fps as 2600x) at 150$ new is within 20% of 9700k and 10% of 8600k and cost over 2.5x & 1.5x more. Even if you bought a 9700k with a semi budget board and just enough cooling you could buy a 2600 and 1070ti for the same amount.

So basically what you're saying is:
- Intel CPU is more powerful and faster than AMD
- AMD CPU is cheaper than Intel
- You value price over performance so in your opinion, AMD is a better choice for you.

Cool, we all have different values. A millionaire PC enthusiasts probably doesnt care one bit about price and would willingly spend $500 extra if it meant even 1% better performance (atleast this is how I would think in that situation).

If the Ryzen 2 provides decent IPC increases then I'll be on that. If not it will be the 9700K for my new rig next year.

Depends. Do you value CPU only operations, or prefer gaming with a GPU? Because as far as gaming, an AMD/nVidia build is clearly the better value per dollar. It's factual, not even debatable.

There's personal justification which is opinion based, and then there's economic facts.

Some people aren't bound to value/dollar and/or have performance targets that are only achievable with Intel's superior IPC and achievable overclocks due to their preferred games not scaling with core/thread count.

For most people though, I agree that something like the Ryzen 2600 is a solid value proposition.

At first, I thought this chip is a neat upgrade - an Intel chip with 8-cores and STIM. Then I realized that due to the minuscule IPC improvements I can't think of any use case for which this would be a good purchase.

This chip is marketed for gamers, yet if you're on a recent quad-core i7, it offers merely 10% higher average and minimum fps in games than the 7700k, and at best (1080P, stock clocks), mind you. Overclock the 7700K and the difference shrinks due to its proportionally larger OC gains - the 10% stock clock speed gap shrinks to 4-5%, climbing back to 7-10% with overclocked Skylake and Haswell i7s. It makes me wonder.. apart from the unreasonable upgrade itch we all feel when something different like this launches, if you already own a recent Intel quad-core it doesn't really make any sense to upgrade for games, as there isn't much performance improvement.

If you're concerned about the future games (what if they become more threaded?), it makes zero sense to upgrade now, since at the moment they perform almost the same, and the infinitely more "future-proof" solution is to upgrade when the games actually become more threaded to a then much better chip built around also actually faster cores.

Since single-threaded performance is the same per clock as with Kaby/Skylake, the upgrade won't perceivably improve the user experience or lightly-threaded productivity performance. If multi-threaded prowess is what you're after, going Ryzen will get you similar frames than what you're getting now with a quad-core and significantly more heavy-weight performance per dollar for multi-threaded tasks.

And even if you're not on a recent quad-core i7 and you're upgrading from something much weaker and more ancient, there's always something offering more bang for your buck than this chip, no matter what you want to use your chip for.

This is incorrect, "AMD/nVidia build is clearly the better" performance per price comparison, "value" is an individual's OPINION, not fact, and is extremely debatable!

Value (definition): a person's principles or standards of behavior; one's judgment of what is important in life.

If the price of an object holds no importance to to an individual, then there is no value in who has the better performance/price comparison. Strickly speaking performance, Intel "is clearly better."


Again, what makes "sense" is a matter of personal opinion; what does or doesnt make sense to you may not be the same for another person. Same argument I made before, if I unlimited amount of money and only cared about having the best performance, I would upgrade now, and when the formula changes and there is a better performance CPU for the application, I would upgrade again...

Also to have "infinitely more "future-proof" solution" is not to wait till the next best thing, because there will always be a next best thing, but to constantly change, upgrade, and 'chase the rabbit.'

@INGTAR33 : If your Ryzen 2700 is at 4.2, your Ram is NOT at 3600. You can barely push 3000 with Ryzen 2XXX series. Me thinks you applied an XMP profile, and then RAM training probably put you at 2600.

I have had Ryzen, the CCX interconnect limits the stability of overclocks, as well as RAM OC. Subsequent AGESA updates never did jack shit.

Multiple times this article mentions the need for a "high end power supply" and in the conclusion says "And unlike Core i9-9900K, you don't need to sink big bucks into a premium power supply."

What difference does the power supply make with these chips ?

Or is the author talking about motherboard power delivery capability?

Still with the damn ad at the bottom edge of the screen?!?!?!!? It`s becoming increasingly difficult to turn a blind eye to this!! It takes up so much of the content! Not even most <mod edit> ad spamming sites do this!

Results for overclocked (default motherboard settings that run boost frequencies way longer than recommended) and more overclocked (manually) only?
How about doing a test by Intel's specs to get some reliable reference numbers?

The used motherboard is the worst boost offender known to Gamers Nexus!
