Beyond the 4090: Why Crypto Mining is Dead and AI is the Only GPU Money Left

Post date: July 10, 2025 · Discovered: April 17, 2026 · 3 posts, 8 comments

Low profitability on modern GPUs, evidenced by users reporting mere $1/day on a 4090, is forcing a reckoning across the industry. The focus is abandoning speculative overclocking for the massive, real-world power draw of AI processing demands.

The sentiment on extreme cooling and overclocking is sharply split. Some, like [MudMan], view the effort to cool cards with 12,000 BTU AC as 'pointless, almost nostalgic instinct,' advocating for focus on reliable operation over marginal gains. Conversely, others defend the pursuit, with [BaroqueInMind] calling the extreme cooling concept 'a genius idea.' Meanwhile, [tht] reported tangible performance regressions (40 FPS with stuttering) when upgrading to an RTX 3060 Ti in *The Finals* despite workarounds.

The clear shift is away from cooling bragging rights and crypto hype. The community consensus is that GPU value has irrevocably shifted to computational workloads, specifically AI. Furthermore, the conversation is flagging specific, low-level technical bugs, such as performance degradation in *The Finals* on Linux, suggesting hardware focus must move beyond marketing hype.

Key Points

SUPPORT

Crypto mining profitability is collapsing on high-end cards.

Users noted minimal returns, citing profitability as low as $1/day on a 4090, necessitating a pivot to AI.

OPPOSE

Extreme cooling demonstrations are perceived as overkill and outdated.

[MudMan] dismissed using massive AC units to cool a 4090 as 'pointless,' demanding focus on broader hardware relevance.

SUPPORT

AI processing is the undeniable future workload for GPUs.

Multiple users established that the massive energy demands of AI computation are replacing the diminishing viability of mining.

MIXED

Minor performance regressions persist even after major component upgrades.

[tht] documented stuttering and low FPS (40 FPS) in *The Finals* after an RX 580 to RTX 3060 Ti jump, despite multiple fixes.

SUPPORT

The focus of hardware discussion must shift from overclocking hype to reliable market use.

[MudMan] stated the concern should be hardware operating reliably without tripping a circuit breaker, not chasing marginal cooling gains.
