4070 Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ASUS is the best-performing 4070 brand in July 2026, moving 3,400 units across 6 ASINs for 57.6% of Top 10 volume. GIGABYTE follows with 2,300 units (39.0%), ahead of PNY on 200 units (3.4%).

With 3 brands splitting the Top 10 and 100.0% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $475.00 to $703.31, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0F7W1KVT3 booked 400 units at $548.61, with ▲ 300.0% MoM change. On the growth side, B0F8LDHQ7Y leads positive momentum with ▲ 150.0% MoM growth on 1K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
