The Intel Core i7-11700KF has the same 8-core/16-thread configuration as the much more expensive Core i9-11900K, which it can almost match out of the box, and beat with a little bit of tweaking. Thanks to its very reasonable price point of only $390, the 11700KF could also be a tempting alternative to the Ryzen 5 5600X or Ryzen 7 5800X.

Either or not Intel solving their nm problem in the next 2 years, investing in Intel stock now seems like a good idea to me.
Banging my head over not investing in AMD at the right time, not long after the Buldozer dissapointment...

For more fairly comparison, please add 10700K Max Power Limit and OC-ed, also add 5800X OC-ed. For now this is misleading. CPUs 3600X, 9900K, 3900X, 11900K, 10900K, and 5900X can be removed, as they are not relevant here (old and different price range)

  • CPU cooler not included
  • No integrated graphics
  • AVX512

    Like sorry, but why these are cons. That CPU is hot as hell, so either it would need some really serious cooler, or like Intel decided, you buy one yourself, cause both you and them are aware of that. For me its one less thing to throw out.

    Cant see iGPU as negative, just cant. Those things shouldnt ever be a part of CPU in the first place.

    AVX512 not being used much, not really Intel fault, cant see why it should be. Any extra stuff is just extra stuff. Might be good in the future, might not be, but cant see it much like con. Its just there.

The prices are good, but power isn't free either. At the OC power consumption levels, 4hrs of idle plus 4 hours of multi thread workload (like games) a day over a year will cost an extra $42 a year over a stock 5800X @ 15c a kwh. And I compare to a stock 5800X because only when the 11700KF is OC'd does it match the stock 5800X. There goes your cheaper purchase price in ~1.5 years, and it only gets worse the longer you keep it.

It kind of is Intel's fault given how much they have fragmented AVX512 support over its lineup. You can't blame developers not supporting AVX512 when so few users have it, especially when Alder Lake (Rocket Lake's successor) won't support it. So it provides little benefit, will likely continue to provide little benefit, and takes up a lot of die space and power budget. It could have been a plus, but Intel can't help segmenting features until the point they become irrelevant.

Hi,
Not sure what Intel was thinking on this series pretty much why I really think it's just filler lake 10900k at least is 10 core.

yeah, only 11400 makes sense. 10th gen is amazing value, 11th isn't, especially so close to Alder Lake. pure prebuilt filler.

^ this.

To be fair tho, I'd have liked the 11700K - 11900K here more but point is, in a direct like-to-like comparison piece like this one, an extra emphasis between the two to-be-compared parts in the form of extra data would've been neat.

As seen in this article, the 11th gen iGPU supports hardware decoding for all variants of HEVC in DaVinci Resolve Studio. That makes timeline performance stellar without the need for proxies. It is a very useful feature.

At $365 USD this might be a solid buy pending the reviews.

Intel Core i7-11700F $365.49
It’s still twice the price of 11400f though. Too much for overall performance difference. But if it gets to current 10700f levels closer to alder lake - than it’s a damn fine cpu for gaming and workloads.

Ok ,but I prefer the 7nm rayzen 7 5800x that has lower consumption and does not heat so much in the long run you pay for it in electricity

Hopefully you realize that when you overclock Intel’s 10th and 11th gen processors, you don’t have to sync all cores at the same exact frequency, in this case 4.9 GHz.

You can use turbo ratios to set a frequency based on how many cores are in use. So for 1-2 cores, you can set a 52 ratio, for 3-6 cores you can set 51, for 7 cores, set 50, and then for all 8 cores under load set 49.

When you do this, then the processor will dynamically adjust its boost frequency depending on the loading of the cores. So in heavy workloads like cinebench, it will run stable at 4.9 as you have done in this review. And for more lightly threaded workloads, the processor will boost to 5.2 GHz for even more single thread performance.

This way you gain the stability of the 4.9 GHz when all cores are needed, and you let the processor boost higher for lighter workloads.

Finally, in your cons section you mention that a con of the 11700kf is “Many BIOS bugs”. But this isn’t the fault of the 11700kf is it?

This sounds like it’s an asus thing. Also you’re running bios 0610 which is not on Asus’ website, and appears to be older than the 0704 bios. Did you encounter the same bugs with 0704?

I've been seeing the vanilla i7-10700F here in Canada on sale in the $335 CAD and 10700 $360, while the 5800x is $570 (all those without the 13% tax)

I think the biggest challenge Intel has is still the 14nm node, although it has came a long way vs gen1.

Who would want to buy this power hungry expensive shit of a CPU? Get i9 10850K if you need 10 cores (selling for 376 bucks atm) or 10700F ($263 atm) or 10600KF/10400F (best buy if you own Z MB)/11400F (best buy with B MB)/ if you need solid gaming CPU. Granted Zen3 are better, but not worth the current market prices imho.

Power consumption :O

Can someone care to explain.... the performance summary with 1080p gaming has the 10700k beating the 11700kf. 10th gen costs £90 less and draws less power. So for a gaming build is it correct to assume the 11700kf is pointless or am I missing something.

Not sure why 11th gen is called rocket lake. Just sounds too epic for something soo non-epic. £90 more, rocket fuel tax?

Now just pair 11700Kf with the only available GPU GTX 1030 and you have a best of a setup that can push through more the 1 FPS.

I know, but for the sake of simplicity I always do all-core OC

Many BIOS bugs
Yeah, in theory we could expect from ASUS to go beyond Intel baseline and solve Intel's problems, but that's not happening, hasn't for years. On the AMD side, AMD took over control with AGESA and offers a highly standardized set of infrastructure/options/settings/descriptions that's implemented in every BIOS

Also you’re running bios 0610 which is not on Asus’ website, and appears to be older than the 0704 bios. Did you encounter the same bugs with 0704?
0610 is recommend by Intel for RKL reviews. 0704 is a beta, and I didn't want to switch BIOS versions between RKL reviews. What I've seen so far is that 0704 mostly improves XMP (over 0610)?

So for a gaming build is it correct to assume the 11700kf is pointless or am I missing something.
Correct, I touched on this in the conclusion

Looks like people have to hurt their pride and go i7 instead of i9 and get like the same gaming performance and save a lot cash in the process well done Intel :roll:

3700x is the real winner, no way is the 11700KF £100-130 more expensive!

... Then again gamers are a special breed.

    Like sorry, but why these are cons. That CPU is hot as hell, so either it would need some really serious cooler, or like Intel decided, you buy one yourself, cause both you and them are aware of that. For me its one less thing to throw out.

    Cant see iGPU as negative, just cant. Those things shouldnt ever be a part of CPU in the first place.

    AVX512 not being used much, not really Intel fault, cant see why it should be. Any extra stuff is just extra stuff. Might be good in the future, might not be, but cant see it much like con. Its just there.
iGPU is a strong component to have now because it is so hard to find an affordable graphics card in the current market. Presently, people are building their entire system less the graphics card with the hope to find one soon™. It is not an uncommon scenario from what I have seen on reddit postings.

No CPU is a con because Intel could include a cooler that would work just fine with the CPU. For the price point, I think one should be included. You can't tell me Intel can't pony up the $25 for a cooler that can handle this CPU.

Integrated graphics is definitely a con. There are people that don't game but need CPU power, the extra expense of a GPU kills the value of a processor. This goes for the AMD side a lot of times too. I'll often go with an Intel build with an iGPU when building for people just because it's a better value. Plus it's nice when trying to diagnose video issue.
