Intel Core i9-11900T "Rocket Lake" Processor Allegedly Catches Up with Zen 3 in Single-Threaded Performance

When AMD announced its Ryzen 5000 series of processors based on the new Zen 3 architecture, the performance of these processors was the best on the market. Even in our own testing, we have found that AMD's Zen 3 core is the highest performing core on the market, even beating Intel's latest and greatest, the 10th generation of Core processors. However, Intel has been doing some silent work and the company has developed a new core to be used in the 11th generation "Rocket Lake" platform. Codenamed Cypress Cove, the design is representing a backport of the 10 nm Sunny Cove design, supposed to bring around 19% IPC improvement across the board.

If you were wondering if that was enough to catch up with AMD's Zen 3 IPC performance, look no further because we have Geekbench 5 performance results of Intel's 35 Watt Core i9-11900T processor. Having a base frequency of only 1.51 GHz, the CPU is capable of boosting one or two cores to the very high speed of 4.9 GHz, giving us a good example of the single-threaded performance we can expect from this CPU. In GB5 tests, the Core i9-11900T has managed to score 1717 points in the single-threaded test and 8349 points in multi-threaded results. Comparing that to something like AMD Ryzen 5800X, which scores 1674 points in single-threaded results, Rocket Lake's Cypress Cove core has managed to be 2.5% faster than Zen 3. However, in multi-threaded results, the AMD chip is unmatched as the low TDP of the Intel processor is stopping it from reaching full performance.

AleksandarKPlease note that this is only a report based on a Geekbench submission. This is not an official review and just one benchmark present. We are not judging the benchmark's credibility and we are just using it as a reference for other processors here. :)
And that is exactly the problem because Geekbench is undergoing changes over time and nobody ever tells you what version you're looking at.

If you're aiming to be more than a clickbait feed, vet your news or add information to make it more useful. Otherwise this sort of criticism will keep flying around and for good reasons. Adding 'allegedly' doesn't really change that IMHO. This is where your value could be and where the news section could become more valuable and especially credible. It will also steer the discussion in comments under it in a much better way because we won't get stuck in these minutia but will actually be able to judge things for what they are and discuss thát.

News sections on tech sites are at a serious risk of becoming glorified PR channels without company branding otherwise... and this will nuke their value then and there. There's a good reason I'm always commenting on those stories with some sort of sarcasm or joke. Its this very reason - you just can't take it seriously most of the time.

CobainI also dont know why TPU is not writing about this subject that I already mentioned a week ago and got attacked by doing so on these forums (being called fanboy etc). It is a major thing right now on tech websites/forums and should call your attention. A lot of whea errors and faulty CPUs due to the high demand, they failing on QC.
You do know those are conflicting reports right ? One is about CPUs being DOA and one about supposedly them failing over time or having some sort of defect, except there is still no way to tell if it's actually the CPUs or issues with the motherboards.

www.techpowerup.com/forums/threads/zen-3-machine-check-exception-cache-hierarchy-reboots-are-back.278491/#post-4458126

This guy is convinced he got three CPUs faulty in a row (having only used boards from ASUS incidentally) which not only sounds impossible but if I were to believe so many CPUs are DOA or dying within weeks then what does that mean ? That almost nobody is getting working CPUs ? You need to open your eyes and come back to Earth.
CobainStill amazed by the amount of people that instantly jumps on any Intel related news article, always judging their products in a bad way. Is like some people can't accept the idea of their products being a good option.
And I am also amazed you literally tried to do the same by posting this.

Key words here are: bad silicon. Wich creates different problems, from doa to bsod, low perf etc

If this was happening with Intel... But when it's AMD is always "no evidencie, conflicting reports, CPUs are fine" even tho most dont even own One or have any experience with One.

Must be fun to buy a CPU and RMA it, waiting a month for a new One,and maybe get lucky to get a good sample.

And when the next version of Zen comes out, Intel will be behind again. If the rumors are true, there's a potential for a nearly 30% improvement in performance with the next generation of AMD chips. And then after that Intel will come back with an answer for that AMD chip. Back and forth. Back and forth.

These two companies fighting each other for the performance crown is like how I remember it decades ago. YAY! The consumer wins!!!

"bad silicon" so it's actually TSMC fault for having more faulty wafers than usual ?

Does anyone else find it kind of ridiculous that Intel's net income for 2020 is 870% ($20.9 bullion vs $2.49 billion) more than AMD's and all they can manage is less than a 5% performance advantage? There's literally no excuse for Intel to not be burying AMD, the same can be said for Nvidia as well, and yet AMD is not only competing, but besting Intel and matching Nvidia which is seriously impressive considering both Nvidia and Intel have a magnitude greater financial resources than AMD does... I just think people don't consider this fact often enough seeing as financial resources in business/production are just about the most determinant factor for success in the overwhelming majority of cases.

Revenue never scales linearly with the quality of R&D. Meaning a company with way less employees and cash flow can compete quite well.

XL-R8RSome quick maths?


4.9GHz vs 4.7GHz max single core boost = 4% difference in clock speeds (being in Intels favour)


1717 vs 1674 is the max single thread score of both CPU's mentioned (being in Intels favour again)... but when we take 1717 (the score of the mentioned 11900T) and reduce it by 4% to take into account clock disparity between CPU's, we actually get a score of 1648 for the Intel part... less than the 5800X's score, at the same clock speed.

Or, in "points-per-ghz":

1717/4.9=350.40
1674/4.7=356.17


Maybe I'm mistaken, but that doesnt equate to a 2.5% lead.





Edit to ask @W1zzard for employment due to my amazing mathematical skills. Any chance? :roll:
This is all very nice but Geekbench is pretty useless when it comes to comparing different architectures. This score shows a 30+% IPC improvement over Comet Lake when Intel claims only 19 (in Specrate2017 int). So this result is obviously not realistic.

Looking at these numbers a lot of people will think Rocket Lake is a big improvement. But the leaked gaming results show that it is hardly better than Comet Lake. I wish people would stop using Geekbench. It doesn’t give an accurate picture of what a processor is capable in real life workloads.

Is this news? And is this controversial? Ice Lake's IPC has been known for years. Rocket Lake is Ice Lake on 14nm for desktop. Stands to reason that it's IPC should be about the same. It'll still be a power hog, obviously.

Dafuq are you even on about man... not every tweet about whatever nonsense is something news worthy. Every day has its own scandal it seems... only to fizzle a week later.

Get a life and kill that social media addiction already - not just you, but in general. Circlejerk frantic clicking doesn't make something true, it only serves to reinforce stupidity and somehow make it credible... because everyone's opinion apparently matters when all filters are gone.

Guess what, the vast majority of opinions are just BS - so that is what Big Data cultivates. Bull.Shit.

"A big company" with 120 units, eh? Jesus Christ...

FrickThey have since removed the tweet and various retailers (swedish link) report no more CPU failures than normal. I am much more inclined to believe there's something going on with some motherboards. 15% of CPUs being DOA would be unheard of.
I'm more inclined to believe there is something going with some freshly registered posters.

It was deleted because AMD contacted then and are analyzing it to provide a solution. It is clear on their Twitter.

All the other rampant complains on that tweet and other fóruns are not deleted tho

And I've so far put together 3 Zen3 systems all of which have had 2 to 3 months of no WHEA issues so based on that metric it's now been definitively proven than Zen3 CPU's have no issues right?

1d10tWow, there's T now? I bet highest end would be 11900FTKS RGB Limited Edition :D
The "T" suffix has been around for ages and ages. It designates a low power desktop CPU, usually around 35W. So it's power optimized skewing more towards low power consumption rather then high performance (like the unlocked K skew). My "NAS" is powered by an Intel i5-4590T CPU, while my Dell 3070 Micro workstation is powered by an Intel i5-9500T CPU. They are both constrained to a 35W power envelope. For everything else, I have a Ryzen 9 5950X.

If that tweet was true, we would hear about it from everywhere and we would have heard about it way earlier.

This is just bullshit. Big retailer that got way more CPU than this company would have raised a comments. Review bellow article would also be bombed Reddit would be full of rage, etc..
Nothing like that happened.

If you ignore that stupid tweet that got deleted, there are 0 evidence of that happening.

But then that means that if Intel is indeed using TSMC for some of their product, they will suffer from the same issues ? Their gaming gpu are supposed to be manufactured by TSMC as well, so we should preemptively avoid to buy them ?

What I mean is they already had i9 and i7 with same core count, and seems counter productive for added concussion to buyer.
Could you guess what separate between 35W 11900T and 125W 11700K? Is it guaranteed that "higher price" 11900T perform better than 11700K? I bet they have 11700T in the making.

Now that old blood is back behind the wheel, I would imagine AMD is going to be in a little bit of trouble over the next few quarters..

I'm not a fan boy for the most part, but he is already pissed at Apple and I'm sure he is not too pleased with AMD either. I'm watching for another Conroe.

Don't get me wrong, I like my AMD, but I have a feeling things are going to get uncomfortable for them soon..
