At Computex 2026, Nvidia officially announced the RTX Spark superchip, an Arm-based SoC combining a 20-core Grace CPU and Blackwell GPU for Windows PCs, targeting high-end laptops and desktops with up to 128GB unified memory (Source 5). Partners include ASUS, Dell, HP, Lenovo, Microsoft, and MSI, with devices shipping in fall 2026 (Source 13). This marks Nvidia's direct entry into the PC CPU market, historically dominated by AMD and Intel. AMD's Computex 2026 announcements were modest: the global launch of the RX 9070 GRE (a cut-down RDNA 4 GPU with 12GB VRAM, $549), the re-release of the Ryzen 7 5800X3D (10th Anniversary Edition, $349), and the new Ryzen 7 7700X3D ($330), alongside extending AM5 socket support to at least 2029 (Source 9, Source 16). Notably absent was any next-generation CPU architecture (e.g., Zen 6), leading analysts to view the lineup as defensive (Source 24). AMD even took a public jab at RTX Spark, emphasizing x86 compatibility and dismissing Arm translation overhead (Source 23). Meanwhile, Intel acknowledged 'a healthy dose of paranoia' over Nvidia's PC entry (Source 11). On the positive side, Barclays raised its AMD price target to $665, maintaining an Overweight rating (Source 25), and Supermicro announced the AMD Helios platform based on Instinct MI455X GPUs (Source 21). However, the US Bureau of Industry and Security closed a loophole allowing Chinese-owned subsidiaries abroad to buy advanced AI chips like AMD's MI350x, potentially reducing a growth channel (Source 8). The RX 9070 GRE review was tepid, citing 12GB VRAM as a limitation at $549 (Source 3). Overall, Nvidia's RTX Spark launch represents a material competitive threat to AMD's PC CPU and GPU market share, while AMD's Computex showing lacked innovation. The net direction for AMD is down, with the full impact expected as RTX Spark ships in the coming months.
