Nvidia RTX 5070 Beats Memory Shortages, Becomes Steam’s Top GPU Amid Questions

According to Tom’s Hardware, the GeForce RTX 5070 posted a 9.42 % share of Steam’s hardware usage in February 2026, a 6.55 percentage‑point jump from the previous month. With Steam’s concurrent‑user base hovering around 36 million, that increase translates to roughly 2.1 million additional gamers reporting the 5070 as their active GPU. The surge is notable because the RTX 5060 series, which suffered from the industry‑wide 24‑GB GDDR6X memory shortage, had been the platform’s leader for the past 18 months. The RTX 5070, launched at a $549 MSRP and now selling about 15 % above that price, appears to have sidestepped the bottleneck, according to the same Tom’s Hardware analysis, which credits the card’s “Blackwell” architecture for more efficient memory utilization.

The report also highlights a demographic shift that may be inflating the RTX 5070’s apparent dominance. Tom’s Hardware points out that 54.6 % of the respondents in February were based in China—a 30.74 percentage‑point rise from the prior survey period. The timing coincides with the seven‑day Chinese New Year holiday, during which millions of Chinese gamers have increased leisure time. Moreover, the outlet notes that many of these users are likely logging in from internet‑café machines rather than personal rigs; a single high‑end café can host 10‑20 systems, each reporting the same GPU model to Steam’s survey. This concentration effect can dramatically skew the platform’s aggregated statistics, a caveat that Valve has not publicly addressed, Tom’s Hardware says.

While the raw numbers suggest a “meteoric” rise, the methodology behind Steam’s hardware survey has been questioned by industry observers. The platform aggregates data from active Steam clients, but it does not differentiate between unique users and multiple sessions on shared hardware. Tom’s Hardware warns that the lack of transparency makes it difficult to verify whether the RTX 5070’s market share reflects genuine consumer demand or an artifact of regional gaming‑café traffic. The outlet draws a parallel to a similar spike in AMD processor usage a few years earlier, which was later attributed to a surge in Chinese cloud‑gaming services rather than a wholesale shift in retail purchases.

Despite the methodological concerns, the RTX 5070’s performance metrics remain compelling. The card’s 24‑GB GDDR6X pool, combined with a higher memory bandwidth per core, allows it to sustain higher frame rates in 1440p and entry‑level 4K titles without the throttling seen on the RTX 5060 series. Tom’s Hardware notes that the card’s price premium—approximately $82 over MSRP—has not deterred adoption among gamers seeking a “future‑proof” solution amid ongoing supply constraints. Nvidia’s own marketing, referenced in the article’s image caption, positions the RTX 5070 as the “upper‑midrange Blackwell powerhouse,” reinforcing the narrative that the GPU can deliver premium performance without the scarcity that has plagued its predecessors.

Analysts will likely watch how Valve’s next hardware survey adjusts for regional anomalies and shared‑device reporting. If the RTX 5070’s share stabilizes above the 8‑9 % range after accounting for these factors, it could signal a genuine market pivot toward Nvidia’s newer architecture, potentially reshaping the competitive landscape against AMD’s Radeon 7000 series. Conversely, if the corrected figures revert to pre‑holiday levels, the episode will serve as a cautionary tale about over‑reliance on aggregated telemetry without granular user‑level validation. For now, the RTX 5070’s ascent—whether real or statistical—underscores how geopolitical events and local gaming habits can ripple through global hardware metrics.
