GALAX GeForce RTX 5070 1-Click OC Performance, Power Analysis & Noise Output

Power Consumption Measurements – Details

All power consumption readings have to do with the graphics card alone and not the entire system’s power consumption. I use Powenetics v2, which allows me to measure almost every system component with high accuracy, including the GPU and the CPU, and with very high poll rates, up to 1000 readings per second, so I can “catch” any nasty power spikes.

I provide more details about my power consumption measurement procedure below.

Idle: The system is idle and at UHD resolution, with no windows or active programs. I let the graphics card warm up for over 15 minutes and take the average reading over 10 minutes.

Multi-monitor: I connect two monitors to the graphics card under test. Both are set at 4K resolution. The system is idle with no active windows, and the refresh rate is at 60Hz on both monitors. With higher refresh rates, expect increased power consumption.

Video Playback: I use VLC Media Player to reproduce a 4K 30 FPS video encoded with H.264 AVC with an overall bitrate of 112 MB/s. All modern GPUs support this codec’s decoding.

GPU Gaming Power Consumption: Cyberpunk 2077 at three resolutions, UHD, QHD, and FHD, at the Ultra Preset and Ray Tracing Ultra Presets. The power consumption readings are from the GPU only, with a polling rate of 250 readings per second.

3D Mark Speed Way Power Consumption: I run this Ray Tracing benchmark at UHD for 30 minutes, on loop. It maxes out the GPU and the power consumption readings are from the GPU only, with a polling rate of 250 readings per second.

Gaming Vsync: I run Cyberpunk 2077 in FHD resolution in medium graphics settings and with V-Sync enabled. I don’t use high graphics settings to allow all GPUs, even low-end ones, to be close to 60 FPS.

Furmark: I let this power virus run for 10 minutes to obtain all required power consumption readings. I also log temperature and GPU fan speed, which is used for noise calculations.

Rendering: I render footage containing many effects in Davinci Resolve at 4K output and with the H.264 codec. I also log temperature and GPU fan speed, which is used for noise calculations.

Peak Power Consumption: Before I start Furmark or any other demanding GPU benchmark, the transient load the benchmark applies to the graphics card’s voltage regulator modules leads to power spikes, which I record with the Powenetics v2 system, utilizing its 1000 readings/sec polling rate. These measurements show which PSU is suitable for the specific GPU, but please note that the CPU also has power spikes, so you must also consider them. Now, if I don’t get the maximum power spike from the above procedure, I will use the max power reading I got from any of the above measurements.

IDLE Average Power Consumption (GPU only)

Power consumption at IDLE is high, but it doesn’t get notably higher with two monitors connected. This is something, at least.

Multimedia Average Power Consumption (GPU only)

Media playback power consumption is increased, especially compared to the RTX 4070 Super.

Gaming Average Power Consumption (GPU only)

The RTX 4070 Super has notably lower power requirements, especially at QHD and UHD.

Gaming Peak Power Consumption (GPU only)

Peak power consumption is increased, for the GPU’s capabilities.

3D Mark Speed Way (GPU Only)

The RTX 5070 is running at its TDP with the demanding Speed Way benchmark. The peak power consumption is about 54W higher than the average reading.

Furmark & Rendering (GPU only)

In Furmark, again close to the 250W TDP, while in rendering, the power consumption is also increased.

Peak Power Consumption (1ms, GPU only)

The peak power consumption is 45W higher than the RTX 4070 Super.
