We're talking a whopping 40 Compute Units of AMD's RDNA 3.5 graphics, which is more grunt than the PlayStation 5's got under the hood.
Speculations suggest that AMD might be brewing two versions of this technology. One is a robust 16-core variant with the full 40 CUs for the GPU, and the other is a slightly more restrained 12-core with 32 CUs. The buzz is that the top-tier chip could rival the RTX 4060 Ti desktop GPU in 3DMark Time Spy.
However, it's important to remember that these are just rumours, not confirmed facts. While AMD has hinted at the existence of Strix Halo through discussions about their open-source ROCm platform, the actual specifications are still up in the air.
Now, if we're to believe the buzz, these chips aren't just about core counts. They reckon the GPU can clock up to a nippy 3GHz, a smidge faster than the PS5 can brag about. Of course, there's more to graphics oomph than just speed—things like how much memory the thing can juggle and how quickly it can do it are essential. But if this rumour's on the money, it's a bit of a corker.
The plot thickens with a supposed peek at the chip layout, showing a GPU that's practically a giant compared to the CPU dies AMD usually plays with. We're talking about 200 square millimetres of silicon real estate, while the CPU dies are more like 80 to 85 each. The word is that the 16-core beast will pair up two of those dies and could hit speeds up to 5.8GHz.
Memory-wise, it's all shared between the CPU and GPU, much like the PS5 or Xbox Series X tech. The grapevine has it that these chips will come with a 256-bit memory interface, packing LPDDR5X-8533, which should give you a hefty 500GB per second of bandwidth. That's not too shabby, and it's what you'd expect in the latest consoles.
.AMD knows its onions when it comes to APUs. Its kit is under the bonnets of consoles and handhelds like the Steam Deck and ROG Ally. These gadgets all have their own performance goals and power needs, but there's no denying AMD's knack for whipping up a top-notch APU with solid integrated graphics.
Its biggest problem, though, is cooling. While the PS5 and Xbox Series X have some fancy cooling tricks up their sleeves, they've got room to spare. A laptop's a different kettle of fish—space is tight, and these rumoured Strix Halo chips might struggle to flex their entire muscle in such snug quarters. Still, they're said to be aimed at the big boys of gaming laptops, which usually have a bit more breathing room and beefier cooling setups.
