Overview
- Tests published July 5–6 by Tom’s Hardware, Wccftech and PC Gamer confirm a China-only desktop card called the “RTX 4080M” that uses a mobile RTX 4080 die on a custom PCIe board.
- The Bilibili reviewer scored the card about 18,600 in 3DMark Time Spy and measured roughly a 100W draw in games, well below official mobile RTX 4080 power specs and likely limited by custom BIOS or drivers.
- Benchmarks versus the similarly priced AMD RX 9070/9700 GRE were mixed: the 4080M led in PUBG and a few titles but fell as much as ~35% behind in Cyberpunk 2077 at 4K, leaving overall gaming performance uneven.
- Street prices rose from roughly 2,000 RMB (~$300) to about 2,700–2,800 RMB (~$400), and sellers offer no warranty or official drivers while relying on community installers and BIOS hacks.
- The cards may suit small-form-factor or low-power builds, but reporters conclude they are a niche workaround born of import limits and AI-driven component pressure rather than a sensible mainstream buy.
