Today we are revisiting our unique Core i9-9900K review and updating it with 95 watt TDP constrained results, essentially consequences based on the official Intel specification. For better context about this please study our opinia Chip:rticle from earlier this week titled “Do We Need to Re- Infinitethe Core i9-9900K?”.

The short model of this is that motherboard makers are presently getting blamed for going for walks the 9900K out of spec, while in fact we strongly consider it’s Intel who’s dishonest their personal spec and pushing board companions to run the 9900K at the default clock multiplier table, in place of on the reliable strength spec.

Whatever the case, out of the field the 9900K isn’t running at the Intel spec, it’s essentially overclocked and this has brought about energy and thermal effects to go through the roof. So in these days’s re-take a look at we're going to be displaying how the Core i9-9900K plays whilst adhering to the Intel specificatiChip: AMDnd comparing that records to the contemporary out of the container experience.

It doesn’t clearly depend where you stand in this, having a aid that shows how those configurations evaluate under the identical check situations is beneficial information in our opinion. For the limitless checking out the MSI MEG Z390 Godlike has been used and for the 95-watt restrained trying out I used the Asus ROG Maximus XI Hero, loaded up the "xtreme" memory profile and opted to use the Intel settings which enforces the ninety five-watt TDP. So let’s get into the results...

Benchmarks

First up are Cinebench R15 multi-threaded rankings. Previously we found the 9900K breaking the 2000 point barrier, however with the TDP limit in area the rating is reduced by 14%, and that places it more or less on par with the i7 -7820X and crucially, intended it became a few percent slower than the 2700X. Already you might be getting a sense of why Intel is happy for board partners to expire of spec.

Next up we've got the Blender short run take a look at and here the 95-watt TDP restricted configuration can best burst up to a hundred and twenty watts for 10 seconds. In different phrases, for approximately half of the check it’s almost fully unleashed, and we had been most effective seeing a 9% reduction in overall performance. That’s still an inexpensive drop, however it’s now not the whole story.

Professionals seeking to make investments a Box rig for rendering will be strolling workloads that take plenty longer than 20-30 seconds. Generally we’re talking hours of rendering work. Whereas we saw a nine% discount in the brief run check, here we’re seeing a 14% reduction Box + greater practical rendering workload. That’s a quite huge drop off and it means the 9900K is now handiest retaining tempo with the Ryzen 7 2700X.

The Corona benchmark runs for over a minute and right here we see a 13% lower in overall performance while electricity limited. The 9900K was 25% faster than the 2700X whilst allowed to run without a strength restriction, but with the ninety five watt TDP enforced it’s just nine% faster. It’s nevertheless faster but the margin isn’t as incredible anymore.

Here we see a 15% reduction in performance for the 9900K whilst the usage of the ninety five watt restrict and this meant it become just four% faster than the 2700X, while we discovered it to be 23% faster formerly.

7-zip compression overall performance isn’t impacted heavily through the 95-watt TDP restrict as we see a minimal 3% decrease.

For decompression the 9900K suffers a chunk more, showing 7% slower effects with the TDP restrict enforced, sufficient to make it slower than the Ryzen 7 2700X. It’s no longer a huge distinction dividing the 2 however.

Excel is the precise instance of a quick workload, at below 10 seconds the 9900K isn’t impacted with the aid of the professional spec and we see an awful lot the same performance with and with out the TDP restrict in area.

Testing with HandBrake we see a 14% discount in overall performance with the TDP restriction enforced, so the 9900K is simply four% quicker than the 8700K and 13% faster than the Ryzen 7 2700X. The 1st and 2d technology Ryzen CPUs don’t try this nicely with AVX workloads, so permit’s have a look at the margins in the h.264 check.

Whereas we noticed a 14% discount in performance walking h.265 encoding, we only see half of that hit with a non-AVX encoding workload. However Ryzen is a whole lot better whilst the usage of h.264 and looks greater competitive here.

The 9900K with the TDP restriction in region dropped all the way down to an all-core of 4 GHz in the h.265 take a look at even as it sustained 4.2 GHz within the h.264 take a look at.

Moving on, right here we see another instance in which the 95-watt TDP sees the 9900K are available behind the 2700X by means of a small margin. It’s additionally thrilling to note that in this Premiere Pro CC export the limitless 9900K matched the 7820X, a a hundred and forty W part at the same technique. I’ve said previously that the 9900K should have at least a 140w TDP score and that does seem to in shape with what we see here.

Playing GPU certain titles like Forza Horizon four suggests no impact and I count on that is how the 1080p consequences will appearance in most tiles. So keep that during thoughts as we’re mainly specializing in CPU sure video games in this assessment, Forza being the exception.

Here we see a 7% hit to border time performance while trying out with Hitman at 1080p, a 6% hit at 1440p, and it’s now not till we reach 4K that the margin evaporates.

Interestingly, we see no actual impact in Project Cars 2 and this title is a chunk unusual in the sense that the 9900K is a lot faster than the 8700K. I’m now not positive why this is as the game doesn’t require 8 cores. Other sources have confirmed these margins, so it’s no longer some atypical computer virus with our check gadget.

There’s no actual margin to speak of while trying out with Rainbow Six Siege both. Any present day CPU going for walks at round 4 GHz appears to work well here.

We do see a pretty hefty 15% performance hit to frame time overall performance at 1080p in Shadow of the Tomb Raider, even though as soon as we get to 1440p we’re almost absolutely GPU certain.

Finally, we have Star Wars Battlefront II wherein we see a small performance drop off at 1080p, nothing severe and by the time we hit 1440p the margins near up to not anything.

Conclusion

First things first, our original Core i9-9900K evaluation is as valid nowadays as the day we posted it. In this 2nd appearance, we have taken a deeper dive at why the 9900K runs so hot out of the box and form an explanation of why a few reviews have been showing greater favorable strength numbers, albeit at decreased uncooked performance output.

Gamers do not need to worry approximately the 95-watt TDP spec, it would not make a great deal distinction both manner and walking overclocked out of the box on Z390 motherboards won’t result in insane thermals and electricity intake for gaming.

But in case you do each work and gaming, and your paintings includes intensive CPU workout routines -- they’re approximately the simplest form of workout routines I appear to do in recent times -- then it’s a specific tale. In our long-run Blender workload temperatures go through the roof when strolling the 9900K out of the TDP spec, we saw an growth of 20 degrees. Of direction, it became a similar story for strength consumption, we noticed general device intake climb with the aid of nearly forty%. But if the 9900K turned into pressured to run with Intel’s TDP spec and abide by using the power limits, it'd be a mighty green eight-middle processor. You’d get 2700X-like performance, even as saving a little over 10% on electricity.

But this is the trouble for Intel, the 9900K was already a difficult promote inside the overclocked configuration utilized by all motherboard makers and nicely... Intel knew that would be the case. It’s a $500 eight-middle laptop CPU competing with a $300 eight-core desktop CPU. As we simply saw with the 95-watt limit, it’s slightly any quicker than the Ryzen 7 2700X. In truth, in a few checks it’s slower, and that’s an lousy end result for a CPU that prices ~70% greater.

This is a massive difficulty for Intel and that they’ve painted themselves into a corner here. For the 9900K to make an oz of feel, for every person who isn’t an severe overclocker, it desires to run at round 70 C with a excellent aftermarket cooler and for that the TDP can’t genuinely be any higher than approximately one zero five watts.

However, even at one hundred and five watts it’s barely any faster than the uncapped 8700K and only a whisker faster than the much inexpensive 2700X, so that you can’t have that with a Core i9. For those of you thinking, a 105 watt limit sees the 9900K susta+ Core clock velocity of 4.15 GHz in our Blender workload and run at sixty nine tiers using the Corsair H100i Pro. That’s a a hundred and fifty MHz increase over the ninety five watt TDP restriction and a 5 degree boom in working temperature.

Basically the 9900K is a surely precise overclocker, in case you invest in proper cooling. The 2700X, then again, is AMD Ryzen situation wherein what you spot out of the box is quite plenty what you get. You can squeeze a bit more out of it and tuning reminiscence sub timings truely help, however won't be able to overclock the snot out of the cores like you may with Intel CPUs.

With motherboards technically overclocking the 9900K to the default clock multiplier desk, 4.7 GHz as an all core as an example, under those situations there isn’t a whole lot left in it. For most 5GHz could be the restrict, accurate luck preserving it cool past that with out a serious amount of time, effort and risk. So realistically you’re talking about up to a 6% improve over what’s proven here while looking at the limitless consequences, and we virtually determined that to be actual while attempting to overclock the 9900K in our day-one overview.

Looking in advance into future reviews, we plan to stick to expose the everyday out of the box experience, and if which means overclocked CPUs, properly that’s what we can display. We'll additionally maintain to publish additional insights and functions like this one when need be.
