Can RTX 3070 Earn ¥1,500 a Month? GPU Mining’s Resurgence Explained

The article examines how AMD’s global release of the RX 9070 GRE amid memory shortages has revived GPU mining, highlighting the Pearl (PRL) token’s PoUW model, short‑term profitability of cards like the RTX 3070, and the rapid price swing that illustrates the cyclical nature of mining markets.

Can RTX 3070 Earn ¥1,500 a Month? GPU Mining’s Resurgence Explained

AMD RX 9070 GRE Global Release

AMD moved the RX 9070 GRE, originally a China‑only SKU, to worldwide sales. The shift addresses inventory pressure caused by a global memory shortage that has depressed the DIY graphics market. The same pattern occurred with the RX 7900 GRE, which was later opened to global channels after Navi 31 chip inventory constraints and the launch of RTX 40 Super cards.

DIY Market Context

Memory price inflation has lengthened GPU upgrade cycles, reducing demand for new graphics cards and prompting manufacturers to seek broader distribution channels to clear stock.

Pearl (PRL) Token and PoUW Mining

Following the 2022 transition of Ethereum to proof‑of‑stake, GPU mining profitability collapsed, prompting miners to look for alternative revenue streams. The Pearl (PRL) project introduced a Proof‑of‑Useful‑Work (PoUW) model that redirects GPU cycles to AI inference tasks. The inference results are recorded on‑chain as work proofs, which generate token rewards.

A wallet allegedly linked to a16z purchased approximately $1.5 million worth of PRL, driving the token price to around $1.50.

Profitability Estimates

RTX 3070 delivers ~58 TH/s, yielding a daily gross income of ¥50.73 (≈¥1,500 per month after electricity costs).

High‑end RTX 5090 cards produce roughly five times the RTX 3070 output.

Difficulty and Price Dynamics

Initial mining pools filled quickly, raising network difficulty. Within three days the token price fell more than 52 %, and total Pearl output now represents about 9 % of the overall network capacity.

Observed Mining Cycle

The sequence observed for Pearl mirrors classic mining cycles: high rewards attract miners → difficulty increases → earnings decline → price drops → miners await the next incentive.

Legal Notice

Mining activities are prohibited by national regulations; participation is illegal.

最近 AMD 有个挺有意思的新动作。
原本是中国特供的 RX 9070 GRE,被发现出现了英文包装,甚至已经上架了海外市场的销售渠道上。
原因嘛,大伙儿应该能猜到了,目前的 DIY 市场因为内存暴涨原因异常低迷,所以更改为全球销售也算是 AMD 缓解库存积压的方式之一。
这事其实并不陌生,当年的 RX 7900 GRE 也是中国特供,然后因为 Navi 31 库存芯片压力以及 RTX 40Super 显卡的出现,后来开放给全球市场。
不同的是,内存原因加上过去两年 DIY 市场经历了一轮漫长的降温,这也导致了玩家换卡周期越来越长。
不过无论是新显卡还是二手显卡,生意还得继续。那要怎么缓解销量低迷呢?
很简单,讲故事。
2022 年,以太坊正式转向 PoS 机制,GPU 挖矿最大的收益来源就此终结。
不过矿圈有一个特点:
算力不会消失。只要显卡还能挖,矿工们就会不断寻找新的赚钱方式。于是,一个叫 Pearl(PRL)珍珠币的项目突然火了起来。
关注显卡的同学可能已经听过了。
因为最近据社区流传消息,一个疑似与知名风投机构 a16z 有关的钱包买入了价值约 150 万美元的 PRL 代币。消息传出后,珍珠币价格短时间内出现大幅上涨。
矿工们自然也就注意到了。
所以币价一度来到了 1.5 美元左右。
以 RTX3070 为例,算力是 58 TH/s,单卡日收益可以做到 50.73 元。
这意味着矿池产出不大变的话,算上电费,一个月就能回本。
而顶级显卡 RTX 5090 的产出是它的 5 倍多。
并且珍珠币还提出了新的计算方式——PoUW(Proof of Useful Work),翻译过来是有用工作量证明。
这啥意思呢?
传统挖矿的逻辑是显卡运行算法,计算哈希、获得奖励。
整个过程中产生的大量计算结果除了维护区块链安全之外,几乎没有其他用途。
而珍珠币提出的概念则是:
既然 GPU 本来就在计算,为什么不能顺便做点“有价值”的事情?
按照官方的说法,矿工未来可以利用 GPU 完成 AI 推理任务,并将这些计算结果转化为链上的工作量证明,从而获得代币奖励。
并且用户可以用 GPU 挖,官方甚至可以提供云端算力,由于收益可观,所以三个套餐很快就被抢购一空了。
然后消息就传到了咱们 DIY 的圈子里,各种显卡要涨价,等等党天塌了,赶快买显卡的声音就相继出来了。
不过真有这么“美好”?
珍珠币上线初期,由于参与人数有限,加上代币价格上涨,不少矿工晒出了相当可观的收益截图。
结果也不难猜,大量算力涌入,矿池越来越多,难度自然也是水涨船高了。
目前珍珠币总产出达到了 9%。
但是价格就坚挺了 3 天不到的时间,目前价格已经暴跌 52% 以上。
也就是说,现在的收益差不多能让显卡赚点辛苦费。并且下降的趋势还在继续…
到这里,大伙儿应该能知道这次挖矿风和显卡价格的结局了。
其实这也不是第一次了,在两年前咱们也报道过类似的案例——
QUBIC
。
故事情节如出一辙,不过这次的珍珠币节奏更快了一些。
而这也是矿圈永远不变的剧本。
收益高→矿工进入→难度上涨→收益下降→然后等待下一个故事。
就是不知道下一个故事对应的是 DIY PC 身上的哪一个部件了。
⚠️:挖矿为国家明令禁止的违法行为,大家请勿触碰。
