AMD’s upcoming laptop processor, codenamed Strix Halo, showed up on Geekbench a few days ago. Shortly after, it showed up in AMD’s Ryzen AI software. Performance-wise, it is tipped to outperform Strix Point because it uses full-fat Zen 5 cores and not a mix of Zen 5 and Zen 5c. Now, a new leak sheds light on Strix Halo’s die size and GPU prowess.
An X user (via Videocardz) has posted some documentation that shows an unspecified Strix Halo package. It measures 45 mm x 37.5 mm for a total die area of 1,687.5 mm2. In this, there are two Zen 5 CCDs measuring 9.05 mm x 7.37 mm each. The RDNA 3.5 GPU measures 19.8 mm x 16.02 mm. This results in a total area of about 440 mm2, making it one of the larger AMD laptop CPU SKUs.
Another document says Strix Halo will be available in three tiers: 55 Watt, 85 Watt and 120 Watt (CPU plus GPU power). Performance-wise, it is tipped to deliver GeForce RTX 4070-level of performance. A previous leak said this SKU had 40 CUs. Lower-end models are rumoured to arrive with 32, 24 and 20 CUs and an accompanying reduction in CPU cores.
It also says Strix Halo will come with LPDDR5x 8,533 RAM on a 256-bit bus for a total memory bandwidth of about 270 GB/s and confirms the platform can be configured with up to 128 GB of RAM.
