Intel Core i9-11900 and i9-11900K (ES) Alleged CPU-Z Bench Numbers Reveal a 12% IPC Gain

Benchmark numbers of an upcoming Intel Core i9-11900 (non-K) and i9-11900K processor engineering samples allegedly obtained on CPU-Z Bench reveal that the chip will deliver on the company's "double-digit IPC gain" promise for the "Rocket Lake" microarchitecture. The i9-11900 (non-K) sample posted a single-threaded performance score of 582 points, while the i9-11900K ES posted 597 points, which are roughly 12% higher than typical CPU-Z Bench single-thread numbers for the current-gen i9-10900 (non-K) and i9-10900K "Comet Lake-S" processors. The multi-threaded score of the i9-11900 (non-K) ES, at 5262 points, ends up just around 5-10% lower than that of the i9-10900, despite a deficit of two cores. Intel's 11th Gen Core "Rocket Lake-S" story is hence shaping up to be that of increased gaming performance from the IPC gain, while roughly the same multi-threaded performance as the 10th Gen "Comet Lake-S."

I won't be upgrading till DDR5 motherboards are the norm. Maybe 2 years from now. Not sure what generation intel will be at then, but I'm sure the performance will be great.

the scores are the same as my 9900K...
so, umm.... where's the uplift?

Lost in transition from 10nm to 14nm? Intel probably had to scale back the L2 Cache amount plus whatever performance enhancements were trimmed.

L2 cache size listed as 512KB x8 in 1st and 3rd screenshots.

Wasn’t the L2 Cache for every core suppose to get bumped to 1.25 MB starting with Sunny Cove?

Nope that's Willow Cove, the cores present in Tiger Lake mobile CPUs.

Since the articles didn't mention any speeds here..

11900 non K - Base, 1.8 Ghz, 3.8 GHz all core boost, 4.4 Ghz single core boost. 65w TDP 8/16 threads

11900K - Base, 3.8 Ghz, 4.8 Ghz all core boost, 5.3 Ghz single core boost. 125w TDP 8/16 threads

Djuice beat me too it, but these new rocketlake processors have mobile level base clocks and 900 mhz lower boost clocks then comet lake. Rocketlake hitting these numbers at only 4.2-4.4 GHz is impressive.

Ah, yes, spoken like a true intel fanboy. And heads up, you're gonna be waiting on DDR5 becoming the "norm" for a long while...

I was honestly only expecting 10%, or even 9.5% rounded up to 10% for that "double-digit" IPC boost (though one could say that 9.5% is double-digit; having 2 digits, just that one of the two is past the decimal). This should theoretically bring them back in line with, if not much closer to, similar Ryzen 5000 CPUs. I do wonder if they will still run super-hot though, or if the updated design backported has some efficiency gains.

Based on what I've heard, it's a bust and doesn't really perform in games.

This was the uarch that was going to decimate AMD. Just imagine it on 10/7nm node. Amazing what intel can do hamstrung.

Considering how poor Intel's 10nm node has been to date... I guess it would've been even worse in terms of clock speeds...

Thought this was the last DDR4 platform?

^ For the majority of people, DDR4 is gonna last a long time, thus DDR5 won't exactly be "the norm" Hell, by the time DDR6 or whatever comes around, these peeps will just be adopting DDR5 lol.

Definitely we still have ddr3 system & ddr3l laptops running strong. DDR5 will take at least 2 years to become "mainstream" & probably 3-5 till it becomes affordable.

Is the only purpose of these chips to retake/reinforce Intel's lead in gaming?

I can't see any other reason for them to exist, considering the drop from 10c to 8 on the top end part.

No one in their right mind would move from a10900K to an 11900K, what with the drop from 10 to 8, for productivity reasons.

You overestimate the intelligence part in making purchase decisions, or indeed underestimate the emotions/e-peen involved.

That's true, you only have to look at the number of dumb ass's paying $1500 for a 3090 (just for gaming) that's only 10% faster than a card costing half as much...

atleast we can be comfortable in the knowledge that its going to be 14nm
