A render diagram of a brand new AMD Ryzen CPU has purportedly leaked on-line, exhibiting a radically completely different CPU construction to the corporate’s present CPUs. The diagram reportedly reveals one among AMD’s new Strix Halo CPUs, and it’s divided into three chiplets. To this point, so ordinary for AMD, you may suppose, till you see the dimensions of one of many chips.
AMD is predicted to carry the lid on its forthcoming Zen 5 structure at Computex in June, and we’d be stunned if a few of these CPUs didn’t make it onto our greatest gaming CPU information. Nevertheless, this leaked AMD Strix Halo chip is kind of a special beast from AMD’s ordinary desktop gaming CPUs, which are likely to have one or two core chiplet dies, and an I/O chip underneath the hood.
On the best of the diagram which you could see under, which was lately shared by X (Twitter) leaker Olrak29_, are the 2 principal CPU core chiplets. These chiplets every include eight Zen 5 CPU cores, making for a complete of 16 cores, and every chiplet is labeled as having 32MB of L3 cache. Nevertheless, it’s that large chip on the left that’s actually putting. It seems to be much less like a chiplet, and extra like the primary chip, even supposing it doesn’t include any x86 CPU cores.
Olrak29_ compares the looks to an previous AMD Radeon RX Vega 64 chip, which had two HBM dies in the identical package deal because the GPU, reasonably than having GDDR reminiscence on the PCB, and there’s a particular likeness. It seems to be as if the 16 Zen 5 CPU cores are secondary to this mighty third chip.
So what’s on this large AMD Ryzen die? In keeping with the diagram label, this chip accommodates a GPU housing 20 RDNA 3+ workgroup processors (WGPs), which might tally with earlier AMD Strix Halo specs leaks. An AMD WGP accommodates two of the corporate’s compute items, and with the RDNA 3 structure you get 64 stream processors in every compute unit, in addition to two AI matrix accelerators and one ray tracing accelerator.
As such, this new CPU’s built-in GPU is more likely to include 2,560 stream processors, 80 AI cores, and 40 ray tracing cores. By way of core GPU specs, it’s extra highly effective than the AMD Radeon RX 7600, which at the moment prices over $250.
Keep in mind that this chip is designed for laptops, reasonably than desktops, but it surely reveals that AMD is lastly actually severe about integrating its GPU tech correctly into its CPUs. Present AMD CPUs with Radeon GPUs, such because the Ryzen 5 8600G, don’t go increased than having eight CPU cores, plus they solely have 16MB of L3 cache, and even the top-end Ryzen 7 8700G solely has 768 stream processors. Add within the matrix AI cores, and AMD actually does appear like it has a CPU that does all of it.
Proper on the backside of the label, we additionally noticed “Zen 5 LP,” which we assume is a reference to some low-power Zen 5 cores which can be additionally embedded on this chip. AMD is already producing lower-power variations of its Zen 4 cores, referred to as Zen 4c, which have the identical structure and directions per clock (IPC) as full-size Zen 4 cores, however have much less L3 cache, decrease clock speeds, and take up much less die area.
It’s fairly potential that Strix Halo doesn’t simply have 16 Zen 5 cores, 80 AI cores, and an enormous GPU, but in addition has some extra lower-power cores underneath the hood.
What’s fascinating about this specific diagram is that it additionally reveals how the CPU core chiplets talk with the huge GPU die, with an interconnect labeled “InFO” within the diagram. After one X person asks if it is a “Zen 6-like interconnect,” Olrak29_ replies “Strix Halo will get it first,” which means this future mammoth CPU probably has some AMD Zen 6 tech in its innards.
After all, that is all rumor and hypothesis proper now, and we have now no details about the precise supply of this diagram. Nevertheless, the diagram does correspond with earlier rumors we’ve seen concerning the AMD Strix Halo GPU. If this diagram is appropriate, AMD can mainly make a CPU that does all of it – multi-threading, gaming graphics, and AI, with no need secondary elements. Intel ought to be frightened.
Hopefully, we’ll discover out extra details about Zen 5 at Computex, however when you’re trying to purchase a gaming CPU proper now, take a look at our Ryzen 7 7800X3D overview, as that is the perfect all-round processor for gaming in the intervening time.
