New Rocket Lake chip combines with Zen 3 in single-core performance

Posted on

A new member of the Rocket Lake family has been located in the Geekbench, this time an ultra-low-power variant called the Core i9-11900T. With 8 cores and a 35W TDP, this chip is the most energy-efficient Rocket Lake benchmark yet. But with a performance that may surprise you. As these results have not been verified, it is best to analyze the data with a pinch of salt.

Intel is expected to release its next generation of Rocket Lake processors in a few weeks (at least until the end of March), marking its biggest desktop architecture update in years, although it may – being a final launch up its sleeve for Comet Lake – a special edition Core i9 10900KS. However, it’s because Rocket Lake is just around the corner that new addition to its 10th gen line doesn’t make much sense.

Whether or not Intel will release a 10900KS chip remains to be seen. At a minimum, Intel has already planned to launch the unannounced SKU. We know this because Intel refers to the 10900KS in a Software Advantage program document (via WCCFTech), regarding the promotion of the Crysis Remastered game package. It is one of the many existing processors as one of the many eligible chips to offer free games.

This specific package, which also offered Street Fighter V and Serious Sam 4, was in existence late last year and while it is in effect until March 31 of this year, it makes us think that Intel has chosen not to go ahead and throw the chip. with your next-generation processor so close.

The latest “KS” chip launched by Intel was the latest generation of Core i9 9900KS. You can think of it as a bin version of the Core i9 9900K. Both are 8-core / 16-thread processors, each with 16MB L3 cache and a maximum turbo clock of 5GHz. However, the 9900KS increased shutdown with a faster base clock (4 GHz vs. 3.6 GHz) and a faster turbo clock. (5 GHz vs. 4.8 GHz), made possible by a higher TDP (127 W vs. 95 W).

It makes sense that a 10900KS would follow the same general design, in that it would be the best silicon capable of reaching higher clocks. But here’s the thing – the 10-core 10900K / 20-thread is already a fast chip, with a base clock of 3.7 GHz and a single-core turbo clock of 5.1 GHz. And if you put it in a cold cooling solution, it can go even higher with Intel Thermal Velocity Boost technology – up to a single-core 5.3GHz and 4.9GHz turbo clock across all 10 cores.

There isn’t a lot of wiggle room to inject more power into the equation, as the 10900K already has a TDP of 125W. The best-case scenario is probably that Intel no longer needs to increase the TPD and, thanks to selective binning, is able to offer a bundle of 10,900 processors with the ability to maintain a base clock of 4 GHz. and slightly faster turbo clocks.

It is not outside the realm of possibilities. In fact, retailer Silicon Lottery makes a living selling the processors it owns, charging more for those that guarantee to run in higher-than-stock configurations (albeit in specific configurations in the BIOS). This includes the 10900K – one of the bundles is guaranteed to run consistently at 5.1 GHz across all 10 cores. And according to the retailer, the 21% of 10900K chips tested were capable of reaching 5.1 GHz or more.

The warning is still Rocket Lake. It seems extremely late to launch a special edition Comet Lake chip, and even if the 10900KS comes out tomorrow or today, it makes more sense to wait. Intel is claiming double-digit IPC payoff with Rocket Lake – which is sure to make the biggest difference in gaming – as well as the addition of support for technologies like PCI Express 4.0. It may even be cheaper at the high end since Rocket Lake will have an 8-core / 16-thread configuration.

Paul has been playing PC games and fiddling with computer hardware from the Commodore 64. He doesn’t have tattoos, but he thinks it would be cool to do one with LOAD “*”, 8.1. In his spare time, he rides a motorbike and wrestles with crocodiles (only one of them is true).

From what we can tell from the Geekbench datasheet, the Core i9-11900T has a super low base frequency of 1.51 GHz, but maintains a surprisingly high maximum boost frequency of 4.9 GHz. While 35W may not seem like a lot of power, it looks like the Rocket Lake cores are energy efficient enough to run 1 or maybe 2 cores at a boost frequency normally found in high power SKUs.

Looking at the results, the 11900T scored 1717 points on the single-threaded test and 8349 points on the multi-threaded score. The single-threaded partition, in particular, is impressive. For comparison, the 11900T is 20% ahead of the previous generation Core i9-10900K – soon – (with a score of 1402).

Switching to Intel’s main competitor, AMD, the Ryzen 7 5800X managed to come very close to the 11900T, with the AMD chip only being 2.5% slower and scoring 1674 points.

However, in multithreaded testing, the 11900T’s 35W TDP actually hurts performance. Comparison of the latest generation Intel Core i7-10700K (not to mention the 10900K); the 10700K managed to be 7% faster than the 11900T. Then, compared to the Ryzen 7 5800X, the lead extends to a performance difference of 22%.

Overall, the Core i9-11900T is an impressive chip, even limited to just 35W, it can outperform the best Comet Lake-S chips in the single-thread department and come close to the best 8-core processor in the Comet Lake-S, the 10700K in multi-threaded performance.

This will really help extend the capabilities of the chip to users who need low power processors. Normally with low power chips like this you would expect big performance penalties. But if those performance numbers are true, then the i9-11900T could rightfully be a great gaming processor for ultra-compact / portable gaming systems with its excellent unique thread counts.

Hopefully this kind of performance will be the same once the chip is brought online and then we can evaluate the chip for ourselves. We still don’t know when the 11900T will be released, normally Intel delays the launch of its ultra low power SKUs long after the launch of its vanilla and overclockable processors.
