Temperature curve
The temperature curves of a GPU vary significantly between constant stress tests and dynamic gaming scenarios. This is due to the different load profiles and the use of modern power management technologies. During a stress test, the GPU remains constantly utilized, resulting in a stable temperature curve. The energy consumption and heat development are even, as all functional areas are continuously active and mechanisms such as power gating hardly ever take effect.
In gaming scenarios, on the other hand, the temperature fluctuates due to strongly varying performance requirements. Complex shaders or ray tracing increase the load, while less computing-intensive sections provide relief. Power gating selectively deactivates unused GPU areas, which reduces heat development in phases of low load. Separate power rails ensure the constant supply of critical components. Accelerated Frequency Switching enables rapid adjustments to clock frequency and voltage, which optimizes energy consumption but results in an irregular temperature curve. Frequent changes between low and high clock rates lead to temperature fluctuations that place demands on cooling. In silent mode, the temperature of 54 °C (gaming) and up to 58 °C (torture) is low enough to achieve and maintain high boost steps even without overclocking.
The memory temperatures of the MSI GeForce RTX 5070 Ti Vanguard SOC are also pleasingly low.
The cooling of the memory modules is supported by the large vapor chamber and the high-quality thermal pads. In silent mode, the lower fan speeds have an effect on the cooling performance, but this is compensated for by the overall lower waste heat. In Gaming Mode, on the other hand, the fan profile is more aggressive, which controls the higher waste heat from the VRAM. The efficiency of heat dissipation also depends on the quality of the thermal pads used (see material test).
Clock rates
The clock rates of the MSI GeForce RTX 5080 Vanguard SOC are pleasantly high. Under typical load, the boost clocks range from around 2,700 to 2,750 MHz, depending on the thermal situation and the performance requirements of the game. This works much better here than on NVIDIA’s FE and, above all, much more consistently than on the MSI RTX 5070 Ti Gaming Trio.
Thermography
The thermographic images of the MSI GeForce RTX 5070 Ti Vanguard SOC after 30 minutes each in gaming and torture mode clearly show the thermal distribution and efficiency of the cooling design. The infrared measurements with the Optris PI 640 illustrate how the cooling works under different loads, with both hotspots and temperature areas with even heat dissipation becoming visible in detail. The thermography shows that the MSI GeForce RTX 5070 Ti Vanguard SOC has a very efficient cooling design that ensures stable temperatures both under moderate load in gaming and under extreme load in the Torture test.
Things are hardly any different in the Torture test:
Backplate and pad problem
Unfortunately, MSI has once again stuck the pad directly under the GPU, i.e. in the wrong place because it is not optimal. But this can be changed and probably will be.
