Due to this price increase, the RTX 4080 is forecasted to have significantly lower sales than the RTX 4090. Specifically, information from Tom's Hardware indicates that sales of the RTX 4080 on eBay are 3 to 4 times lower than its counterpart, the RTX 4090.

It's worth noting that the RTX 4080 16GB has limited supply compared to the RTX 4090. Despite the lower supply, reports suggest that the product is selling much worse than its predecessor, a rare occurrence in previous launches. Now, retailers or bulk buyers are also facing challenges.
At its launch on November 16, multiple sources suggested that the price of the RTX 4080 16GB could reach $1799.99 for the Founders Edition, with premium AIB versions potentially exceeding $2000. According to sales data analysis from Tom's Hardware on eBay, the RTX 4080 16GB is experiencing lower sales compared to the RTX 4090.

According to reports, the RTX 4080 has sold fewer units than the RTX 4090 by 3 to 4 times. This implies that for every 3 to 4 units of the RTX 4090 graphics card sold, there is only 1 unit of the RTX 4080 16GB.
According to Tom's Hardware, every 24 hours, 8 units of the RTX 4080 16GB graphics card are sold, while 64 units of the RTX 4090 are sold. Reported data indicates that GPU sales on eBay have decreased since the product launch with no growth.

Another reason is that the RTX 4080 is currently priced over 30% higher than the MSRP, attributed to speculators selling for profit. According to Tom's Hardware, the RTX 4090 has also seen a price increase of about 38% but remains more appealing to consumers.
