No—the reported Flexpool dashboard does not prove that RTX 4090 or RX 7000 graphics cards produced the displayed mining rates or that the operator received millions of dollars. A December 13, 2021, HotHardware report described three workers labeled as unreleased cards, with extraordinary rates and projected earnings. Those figures were estimates based on the account’s reported rate, not verified hardware, payouts, or profit.
What the Flexpool listing claimed
HotHardware reported that a Flexpool account showed three worker names that appeared to attribute mining activity to unreleased next-generation consumer GPUs:
| # | Preview | Product | Price | |
|---|---|---|---|---|
| 1 |
|
VIPERA NVIDIA GeForce RTX 4090 Founders Edition Graphic Card | $4,440.00 | Buy on Amazon |
| 2 |
|
ASUS TUF Gaming GeForce RTX™ 5080 16GB GDDR7 OC Edition Graphics Card | $1,831.31 | Buy on Amazon |
| Worker label shown in the report | Reported rate |
|---|---|
4090Ti-Overclock-Test |
1.25 TH/s average |
RX7000-Overlock-Test |
507.5 GH/s |
RX7000-Control-Test |
688.6 GH/s |
These are the worker labels and rates HotHardware said were displayed; they are not independently confirmed GPU benchmarks. The report also gave the account an average rate of 2.4 TH/s and a peak of 4.3 TH/s. Read the labels as claims or test names, not as proof of the physical devices running behind them. HotHardware’s December 13, 2021 report did not establish the hardware, coin, or payout history.
Why the claimed rates drew skepticism
The RTX 4090 Ti label was not a verified GPU specification
The report appeared in December 2021, before the cards named in the worker labels were released. The dashboard entry therefore could not serve as a benchmark for a commercially available RTX 4090 Ti or RX 7000 GPU. A worker name is user-entered identification, not hardware attestation.

The reported RTX 3090 comparison shows the scale, not proof
HotHardware compared the first worker’s 1.25 TH/s rate with a roughly 110–120 MH/s RTX 3090 rate cited from WCCFTech. On that comparison, the dashboard rate would be equivalent to roughly 10,000 RTX 3090 cards. That arithmetic underscores why attributing the rate to one consumer GPU looked implausible; it does not verify what equipment produced it.
Do the figures mean the farm made millions?
HotHardware estimated that an account averaging 2.4 TH/s could correspond to around $145,000 per day and more than $4.3 million per month. Those are the report’s rough earnings projections, not audited proceeds or evidence that the operator received that money.
The report noted that electricity costs vary by location, but it did not establish the mined coin, actual devices, power consumption, operating expenses, pool payouts, or realized income. A projected gross figure is not the same as profit, and a dashboard rate alone cannot settle either question.

What hardware might have been behind the account?
The account listing, as described by HotHardware, did not identify how many GPUs were working. The report raised dedicated ASIC miners as one possible explanation for the high rate, but did not confirm that explanation. The dashboard’s GPU-themed labels cannot distinguish consumer graphics cards from ASICs or other equipment.
How Ethereum’s later change affects the story
Ethereum is relevant only as later context; HotHardware did not identify the coin mined by the 2021 Flexpool account, so it should not be described as an Ethereum mining operation. Ethereum.org says The Merge took place on September 15, 2022, replacing proof of work with proof of stake. Its documentation states: “Since The Merge, validators are assigned to secure Ethereum Mainnet, and mining on proof-of-work is no longer a valid means of block production.” The page, updated May 15, 2026, estimates that The Merge reduced Ethereum’s energy consumption by approximately 99.95%. That later change does not establish what the account mined in 2021. Ethereum.org’s Merge documentation explains the change.
