Recent leaks indicate that a new announcement from NBD points to an upcoming chip featuring GDDR7 memory as part of the CPU. A new entry has been added to the NBD logistics and shipping database, which lists Micron’s latest GDDR7 memory as part of the CPU. Micron had previously officially announced its GDDR7 memory, boasting a speed of 32 Gbps and offering up to 1.5 TB/s of bandwidth, along with a 30% increase in gaming performance across various PC resolutions. The memory is also designed for AI Edge and AI PC platforms, such as SoCs.
AMD has dominated the SoC market for “AI PCs,” introducing the first NPU on an AI chip with its “Phoenix” APUs and further refining it in the Hawk Point APUs and the subsequent Strix, which deliver up to 55 TOPS of AI computing power. AMD is also developing the next-generation Strix Halo APUs, which will feature a chiplet design that offers up to 16 Zen 5 cores and 40 RDNA 3.5 GPU cores.
A high number of GPU cores necessitates a large bandwidth. Although AMD’s Strix Halo chips implement an onboard LLC solution in the form of 32 MB MALL, they will require greater bandwidth to support the high-performance throughput of the integrated GPU. The chips will also support memory up to LPDDR5X-8533, which is expected to provide a significant bandwidth boost. So far, there have been no reports of these chips having an on-package memory solution, but they are noted to have capacities of up to 128 GB.
