CMP 170HX prices rose from a few hundred US dollars before the unlock to about 3,000 USD for an 8 GB card by late October 2026, by members' own Discord reports. The wiki's Price history and market page is not a price list: most rows are one person's quote, listing or purchase, and its summaries are marked Reported, meaning single reports rather than reproduced data.
Before and right after the unlock
Before the unlock tool the card traded at about 100 to 300 USD as a mining card, per @c133 (October 20, 2026), and a 10 GB card cost 200 USD in June, per @cuddylac997 (October 7, 2026).
After the unlock reached Reddit in mid July, the first buyers paid 550 to 580 USD and prices hit 800 USD within a day, per @gnasherrr, @phoenixone7 and @sojun80. Through August and September prices climbed from about 800 to about 1,000 USD and then 1,300 to 1,400 USD on average, per @djpandaman and @spectakkular.
October and early November
- October 13: 17,000 to 19,000 RMB in China and 3,000 to 3,500 USD in Western markets for the 8 GB card, per @tony_smartecom, @wakeupmbrc1 and @lenxtroz.
- October 17: sold 8 GB cards on eBay at 2,500 to 3,000 USD against listings of 3,000 to 4,000 USD, per @djpandaman and @feralzi.

- October 31: "fully unlocked" 10 GB cards on AliExpress at 4,088 EUR (40 GB) and 4,976 EUR (48 GB) with 25% VAT, per @petrikrohn_26497 and @stcord.

Why prices moved
The explanations are Contested, meaning members disagree, and none came with sales data. They include sellers repricing on unlock news, the ECC unlock in cmpunlocker 0.5, supply held by large mining farms, and mining becoming profitable again. Whether the 10 GB card costs more than the 8 GB card has flipped over time and is also Contested.
Outside coverage the page cites
Hackaday's "Industrial GPU Adapted For The Desktop" ran on July 22, 2026. On August 7, 2026 wccftech reported prices "exploding" from about 100 to over 1,000 USD, per @cute_sc2.
Tom's Hardware's first article, on 64 GB of VRAM on a "$250" card, was published on August 18, 2026; members said the figure was already wrong, and @bayley_w blamed the August 20 and 21 surge on it. Linus Tech Tips published its CMP 170HX video on September 12, 2026 (Press and coverage).
