AMD Radeon RX 9070 XT Custom Models Reported to Experience High VRAM Temperatures Exceeding 90°C

While the GPU core operates efficiently under heavy loads, the VRAM modules of the AMD Radeon RX 9070 XT can experience temperatures soaring as high as 90°C.

Critical VRAM Temperatures on the AMD Radeon RX 9070 XT

Recently unveiled, AMD’s latest RDNA 4 GPUs are set to hit the market on March 6th. Early access for reviewers has led to emerging insights about these graphics cards beyond their expected performance metrics.

In a noteworthy benchmark test using FurMark, the Radeon RX 9070 XT demonstrated commendable thermal management at peak loads. However, further investigations shared by users on the now-removed Bilibili forum revealed that while the GPU core temperatures remained acceptable, the VRAM temperatures reached concerning levels.

Two different GPU-Z reports illustrate the capabilities of the Radeon RX 9070 XT, highlighting significant variations in VRAM temperatures. In one instance, while the GPU hotspot achieved a peak temperature of 63°C, the VRAM soared to 88°C. Conversely, another test recorded a GPU temperature of 79°C, with VRAM reaching a staggering 94°C.

Interestingly, in the first case, the Total Board Power (TBP) was reported at 237W, which defies expectations, as the RX 9070 XT typically starts at 260W. This discrepancy may point to a software glitch. In the second test, the TBP was measured at a substantial 329W, reinforcing that both cases indeed pertain to the RX 9070 XT, contrary to earlier assumptions.

The RX 9070 XT’s VRAM has nearly hit the maximum thermal threshold of 95°C, which might stem from insufficient airflow or possibly a thermal pad malfunction. Although these temperatures are unlikely to cause immediate damage, prolonged exposure could lead to performance throttling after extended use.

High VRAM temperatures also pose a risk to overclocking potential—a crucial aspect for many gaming enthusiasts. Fortunately, the Core Clock seems to be performing well, leaving some room for overclocking exercises.

As this series of GPUs is new to the market, the issues concerning VRAM temperatures may be isolated incidents related to specific custom models rather than a widespread defect across all units. Further insights are expected as the retail launch approaches on March 6th.
