Default GPU Frequency

Before we look at performance, we need to find out the actual real-world gaming frequency the video card performs.  With both NVIDIA and AMD GPUs today, the GPU frequency is very dynamic.  What may be quoted as the “Boost Clock” is not necessarily the performance it will actually run at.  Typically, GPUs today can exceed the “Boost Clock” dynamically.  We need to find out what it actually runs at, in this way we can see how well things like cooling and power headroom are working. 

To do this we will record the GPU clock frequency over time while playing a game.  We use Cyberpunk 2077 for this with a very long manual run-through at “Ultra” settings.  We also record GPU-Z sensor data to look at GPU temperature, Voltage, and Power.

EVGA GeForce RTX 3080 FTW3 ULTRA HYBRID GAMING Video Card Default GPU Frequency

The default GPU Boost clock on this video card is 1800MHz.  It appears that while gaming the actual real-world in-game frequency seems to mostly be around 1935MHz while gaming.  It remains very solid and consistent, meaning the excellent cooling on the GPU is keeping it consistent.  This is a very high frequency that operates 135MHz over the Boost clock and is compared to a Founders Edition 225MHz over the boost clock.  In our testing of the Founders Edition, it boosted to around 1837MHz, so at 1935MHz this is certainly boosting a lot higher than the Founders Edition would.

GPUz

GPUz shows it maxing out at 1965MHz and 55.5c on the GPU Temperature with 68.1c GPU Hot Spot.  The memory temperature hit 78c and the fan speeds were around 70%.  The Board Power Draw was 383W and the GPU Voltage was at 1.0810V.  As you can also see in the GPUz Sensor Data this video card has multiple EVGA iCX monitoring points for temperature.  That monitoring is what really makes this card very enthusiast.  You can see multiple memory and power and VRM temperatures throughout the card.  It seems components are kept well cooled.

  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.
