This development is no surprise to industry observers who recall similar adaptations with the RTX 20 and 30 series. These companies are leveraging the lower cost of mobile GPUs, combined with budget cooling solutions and simpler PCB designs, to offer more affordable desktop GPU options. The mobile GPUs, which are capped at a power consumption of 175 Watts, are being repurposed without official sanction, with NVIDIA seemingly disregarding this practice. Despite the lack of official endorsement, these modified GPUs are finding their way into the market, providing gamers a cost-effective alternative to the more expensive desktop versions.

While not officially supported by NVIDIA, these cards utilize the mobile GPU dies paired with custom cooling solutions and PCBs to work in desktop PCs. According to reports, the RTX 4080M desktop variant offers 7424 CUDA cores and 12 GB GDDR6 memory, representing a 24% reduction in cores and 4 GB less memory versus the desktop RTX 4080. The desktop RTX 4090M is even more cut-down, with 9728 cores and 16 GB memory—a 40% drop in cores and 8 GB less memory than the flagship RTX 4090 desktop card. Pricing falls between $420 and $560 for the RTX 4080M and exceeds that of even the desktop RTX 4090 for the 4090M variant. Performance and longevity still need to be determined for these unofficial cards. While they present a cheaper RTX 40-series option for Chinese gamers, the reduced specifications come with tradeoffs.
