Ethup Arc Stealth RX 6500 XT 4GB Low-Profile GPU

The Ethup Arc Stealth RX 6500 XT 4GB GDDR6 solves the specific upgrade challenge of slim desktop systems, HTPC chassis, and rack-mounted workstations where available expansion slot height is restricted to the low-profile specification and available card length cannot exceed 170mm — constraints that eliminate the overwhelming majority of discrete GPU options from consideration regardless of price. The RDNA 2 architecture in the RX 6500 XT delivers hardware ray tracing capability, FidelityFX Super Resolution upscaling, DirectX 12 Ultimate compliance, and DisplayPort 1.4 output in a physical package that fits within low-profile slot height requirements while operating within the power budget of slim desktop power supplies in the 150-200W range. The 4GB GDDR6 memory at 18 Gbps across a 64-bit interface delivers 144 GB/s peak bandwidth appropriate for 1080p gaming at medium to high settings in competitive and esports titles where the memory bandwidth constraint limits maximum texture detail settings but leaves frame rate performance intact in the shader-bound regions of the performance envelope. PCIe 4.0 x4 electrical connection — a consequence of the physical die configuration of the RDNA 2 implementation in this chip — provides adequate bandwidth for the GPU’s data requirements at 1080p gaming workloads where the GPU’s compute throughput rather than PCIe bandwidth is the binding performance constraint. Single-fan cooling with a 70mm blade diameter maintains temperatures below 80 degrees in systems with reasonable airflow through the low-profile slot area, an acceptable thermal outcome given the 107W TGP that this configuration imposes and the physical constraints on heatsink volume imposed by the low-profile form factor requirement. A half-height bracket is included pre-installed for standard slim desktop and HTPC installation, with the full-height bracket shipped alongside for use in full-height low-profile slot systems where the bracket height constraint does not apply.
