SLAN 11315-01-20G Pulse Radeon RX 6400 4GB GDDR6 Low Profile Marine Electronic

Compact low-profile Radeon for marine PCs

The SLAN 11315-01-20G Pulse Radeon RX 6400 is a single-slot, low-profile graphics card built for space-constrained marine electronics systems. It delivers 4 GB of GDDR6 memory on a 64-bit interface running at 16 Gbps. The AMD RDNA 2 architecture powers a game clock up to 2039 MHz and a boost clock up to 2321 MHz. Digital output supports a maximum resolution of 7680×4320.

Replaces integrated graphics for multi-display

This card upgrades vessels relying on CPU integrated graphics by adding a dedicated GPU with its own memory and PCI-Express 4.0 connectivity. The jump is worth it when chartplotter software, radar overlays or multiple monitors demand hardware acceleration beyond the processor’s built-in capabilities. Builders needing more than 4 GB of video memory or a wider memory bus should consider a different tier.

PCI-Express 4.0 x4 electrical limit caps bandwidth

The Radeon RX 6400 uses a PCI-Express 4.0 interface limited to four lanes, halving the theoretical bandwidth available to full x16 cards. On older motherboards restricted to PCI-Express 3.0, the effective throughput drops further, which can throttle data-heavy marine workloads. The single-slot low-profile form factor also prevents fitting larger cooling solutions for sustained loads.
