Intel Core i9-11900K or i9-10900KF

[vicar]

I am about to build a new computer, the main use is word, 4k video processing and hopefully some gaming, when i can get my hands on a graphic card.

I am not going to pay silly prices for a graphic card right now, and i am willing to wait for when the current maddening fever has run its course. I have an older card i can use right now.

The main issue is that i have a WD_BLACK SN850 and it seems the 1090KF will not utilize its full potential, but its got 2 more cores than the new 118900k. I am only considering Intel cpus.

I was currently thinking of getting the Gigabyte Z590 AORUS ELITE AX ATX Motherboard and the i9 10900KF.

I have a brand new Seasonic X900 SS-900HP 900w PSU, that i used to test a new build over a decade ago. Can i still use it or buy a new power supply unit? would it

Any advice or comments will be greatly appreciated concerning PSU, CPU and Motherboard.

Thanking you all in advance.

Cat the fifth will be in shortly, I expect, to rule over my answers where they're wrong, but:

the difference between pcie 3 and 4 isn't going to be felt realistically in anything but file transfers - it's not a bottleneck in terms of the hard drive talking to the cpu. I haven't looked at individual reviews for the 10900kf or 11900k but everything seems to be suggesting that the 11900k isn't great value, and the kf is.

My expectation would be that the PSU would be absolutely fine. Time used wears out components, but time on it's own shouldn't do anything to it, perhaps unless you live next to the sea or something? But even then it would be a lot longer I'd guess.

Motherboard too. Given the range of motherboards available for each chipset it's possible you could improve on your choice in terms of value and features but it takes so long to read or even skim every review that you get diminishing returns for drilling down in this area, and tbh, in general if a motherboard has the features you need, it'll do the job for you. The questions could come if you're in a low airflow case with few fans and you're pushing the cpu hard on a board that doesn't have good VRM. A problem which has a number of solutions: don't push the cpu hard; add some case fans tied to the motherboard temperature and aimed at the VRM; get a better airflow case; choose a beefier motherboard to start with. But Aorus is a gaming brand so it really ought to have solid VRM.

FYI you're likely to be waiting a while for graphics cards to return to reasonable prices. They may never.

Pugetsystems has a ton of image editing and video encoding benchmarks:

I know you said you wanted only Intel CPUs,but they are not very competitive for the price. You can get a Ryzen 9 5900X for Core i9 11900K money and it has more cores,and generally faster cores. Also,the Core i9 10900KF is around £400~£450,so again the Ryzen 9 5900X looks a better bet IMHO. For video work generally AMD seems to be ahead. In gaming Intel at best trades blows:

By the time you factor in the much greater power requirements which ends up with much more cooling and motherboard requirements,I wouldn't touch any of the Core i9 CPUs at £400 and above.



Intel is now essential the value preposition. If you can get a 10C/20T Core i9 for between £300~£350 like you could a few months ago,it made more sense.

Edit!!

Also,TBH if you really want an Intel RKL CPU,its best to get the Core i7 11700F for around £300:

Intel motherboards will allow you to uncap TDP,so it will essentially boost closer to a K series model but with a lower overall cost.

The same goes if you want one of the 10C CNL CPUs:

You can also get an OEM Core i9 10850K for around £350(shorter 1 year warranty):

The PSU in theory should be fine,but the issue is with the power draw of the newer CPUs,and the age of the PSU it would be better to get a new one. Also,newer platforms from 2013 onwards require some additional power standards:

Thank you both for your advise, much appreciated.

If going the AMD Ryzen 9 5900X route, what motherboard and psu would you suggest?

If it was going for the Intel i9 10900KF, what motherboard would you advise.

I already have a Noctua NH-D15 for air cooling, Fractal Design Define 7 XL case and ASUS RTX 2060 card. Ideally i would like a 3080 card, but what i have for now will suffice.

At this moment i am with your advise looking at the AMD route.

Once more thank you for your time and advise.

The MSI X570 Tomahawk got some great reviews:
https://www.cclonline.com/product/32...rboard/MBD2865
https://www.amazon.co.uk/MSI-MAG-X57.../dp/B0896G6HSC

However,if you don't need multiple GPUs and multiple PCI-E 4.0 SSDs,a B550 will do the same job and not require active cooling for the chipet:
https://www.cclonline.com/product/32...board/MBD2857/
https://www.cclonline.com/product/33...rboard/MBD2964

The Unify will be the most flexible B550 motherboard if you need a mix of NVME drives:
https://play3r.net/news/press-releas...e-apex-of-am4/

However,the B550 Gaming Edge Wifi for the price has a solid VRM,and decent VRM cooling too:

The other alternatives would the the Asus B550-E and B550-F motherboards. Anything over £180~£200 for an ATX B550 motherboard isn't worth it IMHO,as you can spend a bit extra and get a decentish X570 motherboard.

With Intel it appears the MSI Z590 Gaming Plus and Z590 Tomahawk are the best Z590 motherboards under £250:

If you want to go for something cheaper,the MSI B560 MAG Tomahawk is another contender:

WRT to the PSU,since you are considering an RTX3080,I would probably think of a decent 750W~850W PSU. A Corsair RM/RMx series PSU should be fine IMHO. Seasonic GX and PX series look OK. The Hexus test system with a Ryzen 9 3950X and a RTX3080FE,drew between 450W~500W at the wall. An AMD CPU and a RTX3080FE should be OK on a 700W PSU IMHO.So an aftermarket one,and a 10 core Intel CPU might add another 100~200W to the load at the wall. So let's say 550W~650W at the wall. Even at 90% internal effiency that is 500W~600W internally,at the upper end an 850W PSU would be at 70% usage,so there should be a safe margin on top IMHO.

With RAM I made some suggestions in this thread:

There might be some fancier kits,but I tend to not go OTT on these kinds of things.

I was thinking of getting a Corsair RM850, RM Series, 80 Plus Gold Certified, 850 W Fully Modular ATX PSU.

I already have a pair of Corsair Vengeance LPX Black DDR4-RAM 3600 MHz 2x 16 GB (CMK32GX4M2D3600C18), i am hoping it should work.

I will be looking at the motherboards you have suggested.

Thank you for your detailed response, much appreciated.
