Intel Core i7-11700KF

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

Intel Core i7-11700F $365.49

Hard to call that a good deal when AMD's 3700x si currently $308 on amazon, and intel's own 10700 lineup is under $300.

An 8 core CPU really shouldnt go for over $300 anymore. That goes for the 5800x too, the entire ryzen 5000 series is overpriced.

I just picked up two comet lake CPUs and Z490 boards for a steal.

11th gen is pointless because any gains are being held back by the 14nm+++ limitations.

You only buy rocket lake if you can't find comet lake or Zen3 for a decent price. Throw the teething troubles/BIOS issues into the mix and it looks like a terrible option to go 11th gen at the moment.

Intel should start being 'honest" about their CPU power enveloppe. It's almost twice as much as a AMD cpu by now in heavy workloads.

This is probably a sort of generic question, but what is the ambient temperature during temperature measurements in TPU reviews, and at what speed is the CPU heat sink fan spinning? (Max/Auto/Custom curve/etc). Also, is the reported CPU temperature Core, Package, or something else?

I am getting sort of high CPU Package temperatures (81-82 °C) during a Blender rendering with my i7-11700K using a Noctua D15S and raised power limits, but since my ambient temperature is in the order of 29-30 °C and I use a custom fan curve which starts silent and goes at full speed at about 82 °C, I'm not sure if I should be happy with my results, or if they are proportionally worse than those of the 11700KF review.

Intel Core i7-11700KF Review - Almost as Fast as the 11900K

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...

Temperature testing is kind of irrelevant really, you can only use it to compare against other CPUs tested at the same ambient with the same cooler.

All that really matters is total power consumption as CPUs covert 100% of their input power into waste heat. Take that 1770KF review you linked. Without power limits in place, 373W of system draw is going to be 373W of heat. Technically, pendantically, a miniscule fraction of that energy will be converted to noise - maybe 200mW total, and all the LEDs on the board/cooler/etc will emit perhaps 5mw of non-thermal energy. Still 99.95% of all energy in is converted to waste heat.

Yes, I'm aware that for direct comparisons one would need the same experimental variables, but such variables have not all been noted in the review (or other CPU reviews, as far as I recall), so I was curious if anybody was aware of them.

During a Blender 3D rendering (as in the TPU temperature test) the power consumption of my i7-11700K configuration and no power limits in place is about 280-285W, with the reported CPU Package Power alone being about 170-175W. The entire power consumption (at the wall) includes Radeon RX480 4GB (mostly idling) and a single 24" display (Dell U2412M) calibrated to 120 cd/m2 brightness, through a Seasonic Focus GX 550W power supply.

Does it not depend on the motherboard, BIOS, and silicon lottery of your specific CPU to some extent?

"No CPU power limits" is irrelevant if the board is only capable of delivering 200W to a chip that will happily consume 300W+

I only have Z490 boards, but 'entry' boards like Asus Prime, Asrock Phantom Gaming tend to be both popular and weak when it comes to power delivery - built down to a price rather than built up to a standard. I'm fine with that and use Asus Prime quite frequently but know that it has cost-contrained performance limits that would hamper serious OC attempts and likely struggle to feed a top-end i9 as well as a flagship board with more VRM phases and more filtering.

Other factors are indeed also at play, but I'm using a Gigabyte B560M Aorus PRO AX, which should have good enough VRMs for delivering the current the CPU needs during that test, and the CPU is able of reaching an all-core frequency of 4.6 GHz during a Blender render.

Think you you should just have ditched the manual overclock as it's not a good overclock, just let the ai tuner do it's job.
