AMD’s rumored Zen 5 laptop computer chips look very highly effective, at the least for those who imagine a current put up on the Chiphell boards (through VideoCardz). The APUs, code-named Strix Halo, are mentioned to return with 40 Compute Models (CUs) of AMD’s RDNA 3.5 graphics structure, which is greater than what you’ll discover within the PlayStation 5.
In response to the put up, AMD is prepping two variants. One is supposedly a 16-core mannequin packing 40 CUs for the GPU, whereas the opposite is a 12-core mannequin with 32 CUs. The poster additionally shared efficiency estimates for these chips, displaying the chip with 40 CUs performing about in addition to an RTX 4060 Ti desktop GPU in 3DMark Time Spy.
If that each one sounds just a little too good to be true, it very nicely could also be. These aren’t leaked specs — that is only a rumor posted on a discussion board. AMD has inadvertently confirmed the existence of Strix Halo by means of commitments to its open-source ROCm platform, however as for the specs or efficiency of those chips, we’re dealing in rumors.
Exterior of core counts, the put up additionally claims the GPU will be capable of enhance as much as 3GHz, which is a better clock velocity than the PS5 boasts. There are different components that affect the efficiency of the graphics on an APU — shared reminiscence capability and bandwidth chief amongst them — however it’s a powerful spec, if true.

An alleged chip format shared on the Chiphell boards exhibits that the GPU is greater than twice the scale of the 2 dies AMD is utilizing for the CPU. It’s mentioned to measure round 200m2, whereas the 2 CPU dies are mentioned to measure round 80mm2 to 85mm2 every. The put up additionally claims the 16-core model will use two CPU dies and sport a most clock velocity of 5.8GHz.
Provided that that is an APU, the reminiscence can be shared throughout the CPU and GPU, just like the APUs inside consoles just like the PS5 or Xbox Collection X. The put up claims these chips will sport a 256-bit reminiscence interface using LPDDR5X-8533, which might allow bandwidth of round 500GB per second. That’s an awfully related configuration to what we discover in current-gen consoles.
Rose-tinted specs?
AMD is not any stranger to highly effective APUs, designing the chips inside not solely current-gen consoles, but in addition handhelds just like the Steam Deck and ROG Ally. These gadgets have completely different efficiency targets for various energy ranges, however AMD actually has the capability to design a high-performance APU with sturdy built-in graphics.
If the specs maintain up, the principle challenge going through these APUs could be thermals. The PS5 and Xbox Collection X have unique cooling options and rather more room than a typical laptop computer. With extra restricted area, these rumored Strix Halo chips could not be capable of attain their full potential in a conveyable PC. Nevertheless, they’re rumored to focus on high-end gaming laptops, that are usually bigger and have extra aggressive cooling.
Will probably be some time earlier than we all know extra in regards to the specs. Rumor has it that AMD will launch Strix Halo in 2025, so there’s nonetheless a number of time earlier than we see how the chips form up. This roundup of rumors on Chiphell might maintain up, as varied YouTube and X leakers have recommended, or it could possibly be a bunch of hogwash. We’ll simply have to attend and see.
