March 6, 20215 yr AnandTech already have a review of the i7-11700K up, using a retail model not bound by NDA. https://www.anandtech.com/show/16535/intel-core-i7-11700k-review-blasting-off-with-rocket-lake Despite the claimed 19% IPC uplift, gaming performance on Rocket Lake is deeply disappointing, losing to Comet Lake and even to Coffee Lake in some cases. It also consumes up to double the power of the 5800X, while not performing as well. The reason for these regressions seems to be the increased L3 cache latency, probably due to the difficulties of backporting Sunny Cove to the 14nm process, and with just 16MB of cache (compared to Vermeer's 32MB), the situation is not helped at all. Unless BIOS revisions improve performance (and it is unlikely at this point), Rocket Lake is only good for AVX-512 performance, and not for gaming. For anyone looking to build a gaming PC, it's probably best to stick with what we have now. Some CPUs like the i7-9700F, i5-10400F and i9-10850K are selling at very good prices right now, and 5600X/5800X stock is improving rapidly. It is probably best not to expect that AMD will release successors to the 3600 and 3700X since Rocket Lake will probably fail to be competitive. This is Intel's Bulldozer moment.
March 6, 20215 yr Wow that's actually quite bad. Why would it be slower than last gen? Could an updated BIOS help in this case?

March 7, 20215 yr I find this interesting as I’m in the process of deciding on a new build. I’m coming from an 8086k at 5.1 and a 6700k before that...I’ve always been intel. But it does seem that AMD is a fair compeditor. I understand traditionally a lot of us went with intel for the higher single core clock speeds with P3D being more single that multi threaded....but does that still hold true? And what of MSFS - would the current top end AMD actually be a better offering? Kael Oswald 9950X3D/ 64GB DDR5 6200 @ CL30 / Custom Water Loop / RTX 5090 / 3 x 48" LG C4 OLEDs
March 7, 20215 yr Now let's see the 11900k. That was were the 19% improvement was, I recall. Don't recall it was across the entire series.
March 7, 20215 yr I believe an OC to 5.0 on any intel i7 (9000 series and above) or i9 would be almost as good as the new zen 3 AMD's that are non ok'd. Flight sim 2020 does still need high single core performance but is diminishing returns from higher than 6-8 cores until dx 12 implementation hopefully. Hyper threading etc is not fully used.

March 7, 20215 yr The other problem with this chip is the heat and power consumption.

March 7, 20215 yr Yes, the latency issue is more pronounced in gaming benchmarks. I read that because the rocket lake architecture was designed for 10nm and intel went 14nm with the 11 series, the PCB tracers are longer and increasing L3 and core to core latency. The next CPU cycle if on 10nm may have better gaming results. Edited March 7, 20215 yr by simon747 Simon

In a few years I'd love to hear the full post-mortem on why they were stuck at 14nm for so long. Cheers!

Yes, a bit strange we have been stuck on the same relative single core performance, in gaming at least, and max clock speed for quite a bit now. Thought the 11 series would change that. 😯 Edited March 8, 20215 yr by simon747 Simon

So far there are a limited number in the wild. When we have a larger sample to look at we will get a better picture. I'm reserving judgement at this point. Performance improvements are common with BIOS updates, so... maybe, to a degree.

Its claimed that because Intel own and operate their own fabs, it generates challenges that are unique to them. https://www.pcgamer.com/what-went-wrong-intel/
