3800x vs 9900k

[zx128k]

This is just a debate about these two cpu's.

To keep thing fair, I allowed the 9900k to have the same speed of memory as the 3800x but note the 3800x is more tighter timings (that is the 3800x's overclocking part). The 3800x is the cheaper system.

This is not to say the 3800x will beat all 9900k system builds, the first main issue with the 3800x is the clock speed and RAM speed limit. Your maximum clock is 4.5GHz all cores, I have not seen a 3800x that can run safe voltage above this frequency. Also maximum IF most people can get is 1900 which leaves maximum RAM speed at 3800. With PBO set to motherboard limits, 10x scaling and +200MHz then 11400 cpu is possible in time spy, remember 11700 is approx. the maximum. You can hit over 26k in fire strike. https://www.3dmark.com/fs/20577914

The 9900k can add faster RAM and score higher. Note that most 9900k's can't go above 5GHz and of those 5GHz 9900k's most won't do much above 4.8GHz with AVX instructions. If you are very lucky you can get a 9900k that can do AVX instructions @ 5GHz all cores. Also things can get very hot with the 9900k and you need a very good AIO or full custom water loop for overclocking. The 9900k has no cooler, so you have to buy one yourself.

The 3800x is faster than a stock 9900k with IF 1800 and RAM 3600 with tight timings. This is possible with almost every 3800x I have seen.

9900K just has more overclocking headroom if you are lucky and get a good chip. Faster RAM with tighter timings allow for speeds possibly above the 3800x maximum.

It would seem that the 3800x could be as fast or faster than most 9900k's. Only when you get a very good overclocking 9900k with much more expensive RAM with good timings will you pull ahead.

Overall the 3800x is a cheaper opinion but is only better than the 9900k if most other games see the same performance I have seen above. Even so raw performance looks like it could be the same.

You have just opened a can of worms

 

[sideways14a]

Are you just comparing the raw cpu's or the platform as that can have a massive impact.
I mean, chip for chip the two are very evenly matched with the 9900k having a small advantage in legacy gaming while the 3800x has a moderate multicore advantage elsewhere.
But thats not looking at the big picture, power, heat, no pci4, security and other rather big problems that intel currently has.

Then there is the pricing.
At the end of the day there is a reason why zen2 is flying off the shelves.

It seems amd can’t do right for doing wrong

whilst I think amd line up is stronger then intel at the moment and I own a 3900x myself.

but both processors get the same benifit from ram speeds after a certain point amd have made the IF not allways tie to ram speed and manual adjusting of the IF to the max you can means u can still have faster ram in but you don’t see as much benifit proberly on par with intel scaling

clock speed on the 3800x is indeed lower then intel at stock and o.c and whilst a few amd cpu can hit 4.5ghz is the Exception rather then the rule though 4.3 is about the expected ghz on amd cpu anything above that is a lot more rare.

but whilst ryzen ipc is higher then intel the intel cpu is still quicker core for core though and intel i9 9900k is better cpu then the 3800/3700x

the main thing that goes against i9 is price and if the i9 was priced the same as 3800x currently is intel i9 would be the clear winner.

don’t get me wrong I think the 3800x is also a very good chip but currently the 3800x is priced vs the 9700k not the 9900k and against the 9700k the 3800x is allround the better chip but I think i9 9900k is a stronger chip then the 3800x

 

[zx128k]

Just would be nice to see if the game performance is closer. The 3800x could be a bargain if all you have to do is overclock the IF to 1900 and get decent 3800 ram with manual tight timings. Then you get decent 9900k @5Ghz game performance. Sure you can spend a lot more with the 9900k and get better RAM and performance. I understand the limited scope of the data above and the limits of drawing a conclusion from them. What I did try was to get two systems that were very close to one another. Same RAM speed etc and not base it on cost. The better cooler for the 9900k is because I believe it needs one once you overclock. The 3800x is cooler and performs very well on its stock air cooler. I gave it a AIO so that I could get better all core boosts. 3800x does not need one.

It's a matter of games performance. If you get that great overclocking 9900k and have that expensive RAM kit that does the fastest speed possible with the tightest timings. Then the 9900k is faster but other than that system the 3800x seems faster. I say seems because I have not bench marked apple for apples in real world PC games yet.

9900k

 

[Wucked]

What are we debating? Both are fairly well known by now. If it’s a ‘which should I buy’ debate I’d argue AMD. There’s very little in it with overall performance. But AMD is cheaper, more up to date, has fewer known security issues and has an upgrade path with either more cores on the same gen, or a drop in upgrade with the next gen, next year.

 

[zx128k]

The 9900k at 5GHz and the 3800x stock cores (AIO) with tight ram timing. Both with 3600 RAM kits. The 3800x overclocked via IF to 1900 and ram speed to 3800. The RAM then has its timings tuned for lower latency. This alone closes the gap between the 3800x and a 9900k @ 5GHz with 3600 C16 RAM. They both are equal in 3D mark time spy. Same total score. Both graphics and CPU.

Most website benchmarks don't do the 3800x's overclock correctly. If I was to compare my scores I find that the review systems are far slower than my system even when overclocked.

Example: https://img.purch.com/r/711x457/aHR...BLzkvODQ1MzYxL29yaWdpbmFsL2ltYWdlMDAzLnBuZw==

Their 3800x system does @ 4.3Ghz 11044 but by setting up the system correctly and overclocking the RAM/IF only I get 11300. Turning on PBO I get 11400. Overclocking to full 4.5GHz all cores I get 11700. It's not worth overclocking to all cores 4.3GHz-4.4Ghz. Take a 4.4GHz all core overclock, in time spy its 11504 https://www.3dmark.com/3dm/39889618?
4.3GHz all core overclock, in time spy is 11368 https://www.3dmark.com/3dm/39889679?

Here at another site, https://bit-tech.net/reviews/tech/cpus/amd-ryzen-7-3800x-review/5/

The overclocked 9900k is 11316 and the overclocked 3800x is 10467. For memory, they used 16GB (2 x 8GB) of Corsair 3,466MHz Vengeance Pro RGB DDR4 for all CPUs. This makes the 9900k come out on top, they know it will as well. Yet my correctly overclocked 3800x is 11300.

Maybe more accurate? https://img.purch.com/r/711x457/aHR...BLzkvODQ1MzYxL29yaWdpbmFsL2ltYWdlMDAzLnBuZw==

i know my small group of friends we have pritty high systems and 4 of us have 2080ti and the other 3 have 9900k and there is overall faster then my 3900x altho for me to get 4.4ghz all core oc I’m using 1.425v I can’t get stable any higher then 4.4ghz

but in most games we played there systems are slightly better then mine in games now I don’t have the tightest memory timings etc but I think my system is well maintained and optimised.

but since abba come out at sock setting it’s gotten better and the newer games like borderlands 3 greedfall etc my system seems to higher then there’s.

What are we debating? Both are fairly well known by now. If it’s a ‘which should I buy’ debate I’d argue AMD. There’s very little in it with overall performance. But AMD is cheaper, more up to date, has fewer known security issues and has an upgrade path with either more cores on the same gen, or a drop in upgrade with the next gen, next year.

whilst and is cheaper currently when u want the best and use all the features on the 3800x the price really is quite close not everyone will need or want a X570 motherboard but the price of that generally negates any savings on the cpu side. Now I know people don’t need it want a X570 but with pci express 4.0 etc and more clear bios and not needing to update bios with other cpu etc makes it a prime choice.

And for being upgradeable that’s not really possible at the moment though 3900x shortage and price gauging has made it not a prime upgrade path and 3950x has been delayed.
And technically amd have already done everything they said they would support the socket till 2020 and they have already done that. No guarantees that ryzen 4000 will be am4 and after the issues with am4 this time it would be so much easier for amd to bring am5 for next cpu were only guessing that ryzen 4000 will be am4.

Yep. You can even put a 3900X to a A320 board which cost $60 and still it would boost normally to 4600-4620 at it would do on a X570 Taichi.
