First Comprehensive Review of the Core i7-11700K (ES) Surfaces

Lab501 posted the first comprehensive review of an Intel Core i7-11700K "Rocket Lake-S" engineering sample. The ES has clock speeds matching the rumored clock speeds of the retail version, and should give you a fair idea of how the finished product should perform. The i7-11700K, which is an 8-core/16-thread chip, was tested to be being consistently behind the AMD Ryzen 7 5800X in synthetics such as WPrime, rendering tests such as Blender, video-encoding tests such as Handbrake, and was negligibly trading blows with the 5800X at gaming ±1%. The chip does post leads over the previous-gen i7-10700K in all these areas, though.

Performance aside, the Core i7-11700K is shown to have significantly higher power draw, with the whole-system power draw being 27% higher than a 5800X-based whole-system, when measured using Prime95 (which only adds a CPU load). In a real-world scenario such as gaming, where GPU power draw is added, this whole-system power draw percentage difference should come down. Interestingly, the i7-11700K isn't a "hot" processor, running up to 18°C cooler than a 5800X under Prime95 load.

ThrashZoneHi,
Consoles with amd 8 core potato just confirms an 8 core is fine for gaming hardly a waste.
This comment makes no since considering consoles are using 8 Core Zen 2 CPUs clocks at 3.5GHz with boost upto 3.7GHz. That’s comparable to a Ryzen 7 3700

Hi,
Sense ?
Well it's not overclockable so it's auto turbo potato :-)

Let me correct myself

Series X - 3.66GHz and boost upto 3.8GHz
Series S - 3.4Ghz and boost upto 3.6GHz
PS5 doesn’t have a set frequency but it maxes at 3.5GHz

Non the less unless the 3700 is a potatoe I don’t see how these are

Hi,
I believe you're taking me out of context just a little
Along with the potato referance I also stated it was hardly a waste to use it in a console as someone else stated it was.

Power draw higher and runs cooler than..... ? Isn't that weird? Wonder what cooling solution this one used. I bet it's not an air cooler though.

One point: the Series X can only boost to 3.8Ghz when multithreading is disabled. But yes I agree with you.

moobQuick glance at those Cinebench R20 numbers for the 5800X and you know that benchmark is garbage. Far lower than what basically anyone else has posted, including TPU (627/6123).
My OC 5600x gets 641

I wonder when we will see these paired with Z490 motherboards and which boards will have unlocked PCIE 4.0 ( as a lot of boards do have it built in but not used due to lack of pcie 4.0 on the cpu with 10th gen).

EatingDirtYou understand how biased you sound in this post, correct? The 11700k doesn't look like an awful product if you only compare it to Intel's other products, but it doesn't look particularly appealing when you consider AMD's offerings as well.
The 11700k compared to the 5800x:
11700k has much more power draw(20%+)
11700k is slower in multi-threaded workloads.
11700k is the same speed in games @1080p. Your 4133mhz memory isn't going to make the 11700k any faster than a 5800x paired with similar memory.

It will come down to price and availability. If the 10700k is priced below the 5800x when it releases, or the 5800x is still very hard to get a hold of, the 11700k is a CPU to consider if someone desperately needs a CPU.

I know maybe you're angry that you can't get AMD CPU's, but AMD is definitely not 'wasting' silicon on consoles. AMD had help developing RDNA from Sony & Microsoft and I'd say it has worked out pretty well for them, as they now have a competitive GPU to compete with Nvidia. Not only that, but like the last generation of consoles, AMD has a guaranteed revenue stream that they can rely on for the next 5+ years.
I'm not angry, I don't need a Zen3 CPU, but I maintain my position, AMD is wasting silicon on consoles, they had a good opportunity to take huge market share from Intel, and the margins on selling CPUs is probably higher than from a console given that a series s cost less than a 3700x.
They (AMD, Sony and Microsoft) should have waited to at least have truly next gen games something like Forza or GT.
