The Cinebench R23 multi-core performance of a 24-core Arrow Lake HX mobile chip has leaked on YouTube and the result is quite interesting. The CPU reportedly delivers Raptor Lake-beating numbers while limited to 120 W.

Leaks regarding Intel Arrow Lake CPUs are getting more frequent as we move closer to the proposed October launch. So far, we have seen the alleged performance of the desktop Arrow Lake Core Ultra 200K series chips offer. Now, thanks to Moore’s Law Is Dead, we have a nice look at the possible multi-core performance of a 24-core/24-thread Arrow Lake HX mobile CPU.

The leaker has shared a screenshot of a Cinbench R23 benchmark run for an unnamed ARL-HX CPU. We can see in the screenshot that the Arrow Lake HX chip in question scored more than 32,100 points in the multi-core benchmark. Per MLID, this score is roughly 32,200. If accurate, this will make the 24-core ARL-HX CPU noticeably but not massively faster than the Raptor Lake-HX chips.

Arrow Lake HX vs Raptor Lake HX

Comparing the performance of the leaked Arrow Lake HX CPU to the current crop of Raptor Lake HX CPUs, we can see that the ARL chip is 14% faster than the Core i9-13900HX per our testing. The delta shrinks to 11% in the case of the Core i9-14900HX.

Moving the conversation over to the other side, the AMD Ryzen 9 7945HX appears 4% ahead of the ARL HX chip with an average Cinebench R23 multi-core result of 33,434.

In other words, if the 24-core Arrow Lake CPU under discussion launches with similar performance to what is shown here, AMD’s last-gen Zen 4 CPUs will still be in the lead.

That said, the ARL HX chip in question could very well be a non-retail sample. So, we’ll have to wait for the retail samples to draw final conclusions.

Arrow Lake HX power consumption

An interesting thing to note here, aside from the performance, is the Arrow Lake HX's power consumption figures revealed by MLID. The leaker claims that the ARL HX processor was configured with 120 W but it was using up to 150 W in some scenarios. The 150 W figure roughly matches the Core i9-13900HX and the Core i9-14900HX’s max turbo power. So, Arrow Lake HX seems to be as power-hungry as its predecessors.

Moreover, MLID suggests that the desktop Arrow Lake chips can consume “possibly” double the amount of the HX chip which means up to 300 W. This is a little disappointing if true as not only has Intel promised efficiency gains for Arrow Lake CPUs, but the Zen 5 desktop chips like the Ryzen 9 9950X reportedly only pull close to 200 W at peak. So, with 300 W, the ARL-S processors will lose to AMD in the efficiency department.

As always, it is important to remember that everything MLID has revealed is unconfirmed at this point. Therefore, take the information with a grain of salt.
