AMD’s Radeon RX 7000 series GPUs are sparsely available across popular notebooks. NVIDIA’s RTX 30 and 40 series parts are the dominant force across both budget and enthusiast offerings. The Radeon RX 7600S is an RDNA 3 GPU fabbed on TSMC’s N6 (6nm) process. Featuring 1,792 shaders alongside 8GB 16Gbps GDDR6 memory via a 128-bit bus, it has an external bandwidth of 256GB/s, backed by 32MB of on-die cache (Infinity L3 Cache).
The RX 7600S has a TDP of 80W, and trades blows with the RTX 4060 mobile. At 1080p rasterization, the latter is nearly as fast as its 80W GeForce rival. It runs at a core clock of 2,446MHz versus 2,612MHz on the 4060M.
Switching to ray-tracing kills the performance of the Radeon, making it just about 50% as fast as the RTX 4060 mobile. To top it off, we’re looking at native 1080p performance without DLSS 3, which further exacerbates the delta.
Both the GPUs come with 8GB of GDDR6 memory, but the RX 7600S runs into a severe memory bottleneck with ray-tracing enabled. On the other hand, the RTX 4060 mobile does an excellent job losing just about 15 FPS with RT switched on (with the TDP raised to 115W+25W).
