Both GPUs share a 128-bit memory bus, which makes the generational memory technology gap between them all the more decisive. The MSI RTX 5060 Ti uses GDDR7 running at an effective 28000 MHz, while the RX 7400 relies on GDDR6 at 10800 MHz. On the same bus width, the only way to dramatically increase bandwidth is through faster memory — and GDDR7 delivers exactly that. The result is a maximum memory bandwidth of 448 GB/s on the 5060 Ti versus just 173 GB/s on the RX 7400, a difference of nearly 2.6×. Bandwidth is the pipeline through which the GPU feeds its shaders with texture data, geometry, and framebuffer contents — starving that pipeline leads to stutters and frame-time inconsistencies, particularly at higher resolutions and with complex scene geometry.
Capacity tells a similarly lopsided story. The 5060 Ti ships with 16GB of VRAM, double the 8GB found on the RX 7400. Modern game assets, high-resolution texture packs, and AI-assisted rendering features are increasingly pushing VRAM requirements beyond 8GB. A GPU that runs out of VRAM spills data to system RAM, causing severe performance penalties. The 5060 Ti's headroom makes it significantly more future-proof and better suited to 1440p and 4K workloads. Both cards support ECC memory, a feature relevant mostly in professional or compute contexts, so this shared trait is effectively a wash for the typical user.
In the memory category, the MSI RTX 5060 Ti holds an emphatic advantage on every meaningful metric — bandwidth, capacity, and memory generation — despite the identical bus width. The RX 7400's GDDR6 configuration is a real bottleneck relative to its competitor, and no other shared spec in this group offsets that gap.
