Power and Temperature

To test the power and temperature we perform a manual run-through in Cyberpunk 2077 at “Ultra” settings for real-world in-game data.  We use GPU-Z sensor data to record the results.  We report on the GPU-Z sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data.  For temperature data, we report the GPU (Edge Temp of the GPU) as well as Hot Spot (Junction Temperature) when available for our temperature data. 

EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING Video Card Power

The AMD Radeon RX 6800 has the highest GPU Chip Power Draw at 256W, the EVGA RTX 3080 FTW3 ULTRA HYBRID GAMING uses much less GPU power draw at 230W, and when overclocked only rises slightly to 234W. The 6800 XT doesn’t read board power, but for the EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING it does. At default board power is 383W and overclocked rises to just 391W, staying under 400W is impressive.

EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING Video Card Temperature

Temperature is where the EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING video card really shines. At default, fan speeds the GPU temp is only 55.5c and Hot Spot is 68.1c, while the Radeon RX 6800 XT is blistering hot at 78c GPU and 96c Hot Spot. When we overclocked the EVGA video card we did set the fans to 100%, but that still maintained a really cool GPU temp of 51c and a Hot Spot temp of 63c. This AIO works really well.

To compare temperatures with the Founders Edition video card, our Founders Edition hit 81c on the GPU at default. That’s a huge difference that this AIO is making.

  1. Thanks [USER=3]@Brent_Justice[/USER] for another awesome review. A truly impressive card. I’m constantly at ends in deciding if I want to mod, and then invest in everything it takes to get a top-end custom loop setup going but things like this make it easy for people, when they can get one. Now granted once done most parts can be reused for future upgrades but it is a bit of money and time to do so. I priced around a $1K to upgrade my Strix 3090 to full block, and all the other parts, and never committed to it.

    In terms of the power limitations it’s an unfortunate common design choice that I’ve noticed with most manufacturers to use reference, or similar, PCBs and not include a BIOS that will allow for greater adjustments. I couldn’t tell you how much time I spent looking for a 3090 with a factory loop that also included one of the custom PCBs that allowed for increased power. Other than the Kingpin and FTW3 Ultra Hydro, and some mythical things from overseas, I never did find anything else. Pretty much everything I saw had the standard 2x 8-pin connectors.

    However the FTW3 Hydro 3090 appears to use the same 240mm radiator as the 3080 and I have doubts if it would still perform as well as what you saw with the 3080 when fully overclocked. Really seems like they should’ve used a 360mm with the 3090 but can’t say I’ve read any in-depth professional reviews like yours to examine it in-depth.

    In either case I’m on the list for one of the FTW3 Ultra Hydro and who knows, maybe when the 4090s come around someone will offer one and it’ll be accessible.

    Bottom line though is that these 3080s look to be the cream of the crop and if someone can get at MSRP they’ll be in for a treat.

  2. I have a standard FTW3 Ultra Gaming, no doubt it is a good card.

    I have a custom loop and a EKWB block on the GPU.

    Even running the standard stock cooler, I had no need to overclock the GPU.

    The stock cooler is very quiet. I had to really convince myself it was worth the time to put a block on.

    At any rate, I think it would be interesting to run an air cooled Ultra vs this watercooled Ultra and see if there was any real advantage to paying extra for it.

    In reading other reviews on similar things, on other sites, generally the performance is very similar when using stock clocks. The big difference comes down to noise levels and when overlocking it.
