Was looking around for Thunderbolt 3 eGPU enclosures for my GPD Win Max 2 and found this gem. This is a pack with both the eGPU enclosure (Which itself is around $500) bundled with a Sapphire Pulse 8GB RX6600 XT (@$400-450).
From the Manufacturer page:
The GearBox 500 PULSE RX 6600 XT Thunderbolt™ 3 eGFX Solution features the low-noise and high performant 8GB PULSE RX 6600 XT graphics card. Powered by the latest AMD RDNA™ 2 architecture, this PULSE RX 6600 XT Thunderbolt™ 3 eGFX Solution delivers a noteworthy boost to professional and gaming applications and also features a lightning quick 40Gbps Thunderbolt™ 3 connecting interface that handles various types of data and is capable of charging a Thunderbolt™ 3 configured device.
Can offload the RX6600XT and basically get a eGPU case for cheap.
my man, the 6600 xt is regularly $350-$400 now.
