ZOTAC Gaming GeForce RTX 2070 Blower Power Consumption
For our power testing, we used AIDA64 to stress the ZOTAC Gaming GeForce RTX 2070 Blower, then HWiNFO to monitor power use and temperatures.
Power use for the ZOTAC Gaming GeForce RTX 2070 Blower shows it idles around 14watts and ramps up to 178watts under full load. Power use is a significant factor when a server has 8x GPU’s running under the hood. The ZOTAC Gaming GeForce RTX 2070 Blower shows considerable power savings over just about every GPU we have tested so far.
ZOTAC Gaming GeForce RTX 2070 Blower Cooling Performance
A key reason that we started this series was to answer the cooling question. Blower-style coolers have different capabilities than some of the enormous dual and triple fan gaming cards.
Temperatures for the ZOTAC Gaming GeForce RTX 2070 Blower shows a slight decrease in idle and load temperatures over the ASUS Turbo-RTX2080-8G Blower-Style we tested. We kept the blower speeds at stock settings, unleashing full fan speeds would make a big difference in temps here. In dense servers and workstations, it is common to run at high fan speeds.
Final Words
The ZOTAC Gaming GeForce RTX 2070 Blower is yet another GPU that fits well into server platforms. Multiple GPU workstations can also benefit from Blower cards, lower power draw and heat output can be an issue with these platforms, the ZOTAC GeForce RTX 2070 Blower fits these types of systems well. For our purposes, the lack of SLI is not an issue as GPU compute applications do not require this. SLI would come in handy for gaming as an example, but on the compute side, the trend is for applications to scale across many GPUs. If you want SLI, you will need to move up to the NVIDIA GeForce RTX 2080 series.
The big take away from this card is the significantly lower power draw. This can be as much as 50 watts lower under full load compared to last generation 1000 series Pascal cards. In turn, when running multi GPU systems that can mean substantial operating savings both from the cards themselves, but also regarding chassis fans moving air.
At this time the ZOTAC GeForce RTX 2070 Blower was about $100 more on Amazon than GTX 1080 cards at the time of this writing. However, with generally better CUDA and OpenCL performance, along with lower power consumption, these are certainly worthy upgrades.
Great job, this article. Deep learning benchmarks would make it even better! Especially for this card, as many claim its has the best value for DL: http://timdettmers.com/2018/11/05/which-gpu-for-deep-learning/.
