Modded RTX 4080M desktop GPU lags behind cheaper RX 9070 GRE
A modified RTX 4080M desktop GPU using salvaged laptop silicon costs about $400 in China but underperforms the similarly priced RX 9070 GRE in all but one game tested. The custom card draws only 100W under load, offering power efficiency at the cost of performance. It loses to the RX 9070 GRE in every benchmark except PUBG.
Meridian48 take
While the low power draw is notable, the performance deficit makes this a niche curiosity rather than a practical alternative to official desktop GPUs.
