Temperature, Power Draw, and Overclocking
The RTX 5070 NB EX has a GPU clock of 2325MHz and a boost clock of 2512MHz. In tests, we were able to reach the 2917MHz boost. The memory clock is set at 1750MHz by default, which is the standard memory frequency for the RTX 5070.
The card draws up to 255W at the default settings, which is slightly more than the Colorful declares. It’s a maximum value, not a constant power draw. The maximum power limit can be raised to 105%, which gives us a maximum of 264W. The total power draw is significantly higher than that of the RTX 4070 or RTX 4070 Super. The last-generation cards were closer to the 200W mark.
We were surprised by how high the core on our card could overclock. The maximum boost reached 3360MHz, and at these settings, it passed the 3DMark stability test multiple times.
Nvidia limits memory frequency. We could only go up to 2000MHz (from stock 1750MHz). The overclocking slider ends there for the current drivers and used software.
After overclocking, temperatures went up to 76.1°C, which is still not bad, and the fans were not spinning at their maximum speed.
Overclocking gives us a performance gain between 1% and 7% in games. If we miss a few FPS for smooth gameplay, then it’s worth it. In other cases, we can enjoy optimal performance at the stock frequencies without the hassle of stability tests.
