13700KF or 13700F combo

[Lovec1990]

Greetings,

im in process of buying new PC but got to dilema:

1.)13700KF with:
-Z790 mobo
-AIO cooler
-6000mhz CL30 memory
- Big-tower case

2.) 13700F with:
-B760 mobo
-High end aircooler
-5600mhz CL28 memory
-Midi-tower case

im willing to wait for 13700F,but is there any good reason beside better performance to pick option 1 over 2?

What is your use case? What is the price difference?

If you don't have a spare dedicated GPU it's best to get a K CPU with iGPU...

What is your use case? What is the price difference?

Gaming, cannot tell full price diffrence becouse price of 13700F and B760 is not fully known, but rough estimates say 13700F combo should be 270-350€ cheaper.

If you don't have a spare dedicated GPU it's best to get a K CPU with iGPU...

both combos gonna be by current plan be paired with RX 7900 XT

If you're getting issues for some reason with your RX7900XT , you can always fall back on a CPU with iGPU and still use your system....

The F CPU's don't come with iGPU.

 

[Lovec1990]

im aware of that

 

[ir_cow]

Non K CPUs have the system agent voltage locked, which limits the memory speeds.

 

[LFaWolf]

What is your GPU and monitor resolution?

If the price difference is less than $500 total, I would get the K version. if more than that, then it depends on the rest of your system and your financial situation.

This ^^ If the 13700 / 13700F is anything like the 12700 / 12700F it's going to be a gaming beast.

i still use atm 1080p monitor, but i might upgrade it down the road. i was eyeing RX 7900 XT with both combos. only real grip i have with 13700KF is that i would need AIO cooling. And for the record i had bad experience with AIO so i try to avoid it. Financial situation is good, but 13700F combo looks better value and more reliable couse it lacks AIO compared to 13700KF combo

In that case you can go for the 5800X3D as an air-cooler will be sufficient for this 105W chip. It is only 10% slower in games compared to the 13700k (13700K Review) but will sip much less power and thus run cooler. Also we don't know for sure if and when the 13700F will be out. 13700KF is a hot chip and will definitely require an AIO if you wish to get the maximum out of it. Even a 13600k will require a decent AIO to keep it under 90C under heavy loads. But if you really want the intel platform then you should get the 13700K (not KF) as the igpu works wonders in rendering and editing stuff while also acting as a backup incase of a dgpu failure.

Just wait until Jan 5 or 6 then. Intel is supposed to announced the non-k Raptor Lake during CES. You will see the speed, benchmarks and reviews. Personally I think the non-k should suffice for your use case.

13700F will launch on 3rd January

i know hence 13700F combo has 5600mhz memory

True, but issue that in this test 12700K and 12700 use same memory while i would use faster ram with 13700KF so 13700F will fall behind it more

 

[phanbuey]

I have the 13700KF so for comparison in a heavily ram bottlenecked game, when I was OC'ing the kit (Gskill ripjaws S5 2x32GB 5600 cl30):
stock ram 5600 cl30-36-36-89 @ 1.25v, shadow of the tomb raider benchmark 1080P lowest ~280 FPS avg with ~200fps min(varies from 198 to 205)
OC ram 6200 cl32-38-38-76 w trefi @ 56000, auto trfc, mode 3 (msi latency) ~ 330 FPS avg with ~235 fps min (varies from 230 to 240+)

Chip limited to 230W with +3 turbo ratio OC, -.02v offset.

 

[Lovec1990]

so its quite a diffrence

 

[phanbuey]

so its quite a diffrence

Can be, depending on the kit and the game. SOTTR is one of the really sensitive ones to ram latency. I think the KF has a faster ring as well.

At 4k ultra settings the benchmark is identical -- but yeah having ability to OC ram, plus with faster 7400-8000 kits coming out IMO it's worth.

 

[Lovec1990]

my issue with 13700KF is that it needs 360 AIO or better to cool it.

 

[Space Lynx]

I had no idea ram could make that big of a difference @phanbuey

my guess is, its still only a handful of games though. most games it prob wont matter much

 

[phanbuey]

my issue with 13700KF is that it needs 360 AIO or better to cool it.

So you can turn a 13700kf into a 13700f pretty easily. They undervolt really well, and are actually very efficient when you start power capping them. I have mine in an ITX build and have no temp problems at all at 230W, at 190W I could air cool it.

Yeah it really depends -- but 1080P and 1440P resolution with lowish gpu bottleneck games is where Alder Lakes, Zen 4, and Raptor Lakes seem to scale with ram -- I expect Zen 4 X3D to be an absolute beast here.

 

[Lovec1990]

isnt undervolting dangerous?

 

[phanbuey]

isnt undervolting dangerous?

No not at all.

Testing and Tuning the new 13900K for Efficiency - YouTube

Actually recommended on these chips since intel went crazy with the power curve. It's more dangerous to let them run their stock curve .

what if i just power limit it at 250W?

 

[phanbuey]

what if i just power limit it at 250W?

250W is pretty high so you might still need an AIO for that. Basically the difference from 150W-250W in games is actually 0. If you cap it there (150-190W), you will be able to air cool with no issue even under stress tests/cinebench etc.

You can actually put it to like 150W and tell the turbo ratio to go +2 or +3 and you will get MORE performance in games, and still be fine under air for all core load.

but what is safer or less harmfull for CPU undervolting or power limiting it?
