Ethup Arc Nano RX 6400 4GB Graphics Card

The Ethup Arc Nano RX 6400 4GB solves the specific design problem of delivering discrete GPU performance in system builds where external power connectors are unavailable, case height is restricted to low-profile, and acoustic output must remain at or near inaudible levels — a combination of constraints that eliminates virtually every other discrete GPU option from consideration. The card draws its entire 53W TGP directly from the PCIe x8 slot power delivery pins without any external connector requirement, enabling installation in systems equipped with power supplies that lack GPU power connectors entirely, including many OEM business desktops and pre-built systems designed without gaming GPU installation in mind. GDDR6 memory operating at 16 Gbps across a 64-bit interface delivers 128 GB/s of peak bandwidth — sufficient for 1080p gaming at medium to high settings in competitive titles and esports games, with low-settings capability in graphically demanding AAA titles where the memory bandwidth constraint becomes limiting. The single low-profile fan operates below 1,200 RPM during typical gaming workloads and drops to a near-silent 600 RPM during desktop use, making the card acoustically unobtrusive in quiet office and living room media center environments where noise output from consumer hardware is a genuine usability concern. The half-height, half-length form factor enables installation in the smallest desktop cases and the OEM mini-tower form factor machines that dominate business computing environments being repurposed for light gaming duty. Display output is provided through one DisplayPort 1.4 port supporting 4K/60Hz and one HDMI 2.1 port supporting 4K/120Hz — outputs that adequately serve the primary use cases of this card’s target buyer without the connector count that would be appropriate in higher-power designs. Hardware H.264 video decode acceleration offloads 4K HDR streaming playback from the CPU, reducing power consumption and enabling smoother 4K streaming on systems with modest processor specifications.
