AMD Radeon 840M (RDNA 3.5/4nm/Shared LPDDR5X/Budget Mobile Integrated) Review
The Radeon 840M is AMD's budget-tier mobile iGPU, built into the more affordable Ryzen AI 5 300-series "Krackan Point" chips rather than the higher-end Strix Point silicon that carries the 880M and 890M. Found in the AMD Ryzen AI 5 340.
Early Geekbench OpenCL results showed the Radeon 840M outperforming the previous-generation Radeon 740M by roughly 19%, suggesting AMD carried its RDNA 3.5 efficiency gains down into its budget mobile tier rather than reusing older graphics IP.
A Cost-Down RDNA 3.5 Part
Early Geekbench OpenCL results showed the Radeon 840M outperforming the previous-generation Radeon 740M by roughly 19%, suggesting AMD carried its RDNA 3.5 efficiency gains down into its budget mobile tier rather than reusing older graphics IP.
Built for Affordable Thin-and-Lights
The 840M targets mainstream and budget laptops where battery life and price matter more than gaming performance, trading compute unit count for a smaller die and lower power envelope than its Strix Point siblings.
Comparison to Alternatives
Against the AMD Radeon 780M, the 840M trails in raw performance since it targets a lower-cost segment, but closes some of the gap thanks to RDNA 3.5 architectural improvements. Against Intel's integrated graphics in similarly-priced Core Ultra "Series 1" laptops, the 840M is generally competitive in casual gaming and media workloads.
