Note on comparisons for this review

Please note that we have included all of our previous test data from our last set of RTX 4090 reviews, which is about a year old at this point. In that period we have since updated our test system so the data is not apples-to-apples. However, as we are running the same thermal test (a 30 minute loop of Metro Exodus Enhanced Edition), I decided to keep our older thermal and noise level data in the charts to provide some context to the results of this Acer RTX 4090. I was also able to re-validate the results of Nvidia's 4090 FE, with thermals coming in within 1C of the results I showed previously, while the card averaged just a 9MHz difference in operating clock speed. This is not a perfect scientific approach as we are changing a key variable (the test system) but I am confident the results are close enough to still be useful as part of this review. I am only doing that for the thermal, noise and clock speed data however – for our game benchmarks, I will only be comparing the Acer 4090 to the Nvidia Founders Edition.

Software and Games List

• Alan Wake II (DX12)
• Assassin's Creed Mirage (DX12)
• Cyberpunk 2077 (DX12)
• Forza Horizon 5 (DX12)
• Horizon Zero Dawn (DX12)
• Metro Exodus: Enhanced Edition (DX12)

We run each benchmark/game three times, and present mean averages in our graphs. We use FrameView to measure average frame rates as well as 1% low values across our three runs.
