Test Setup
For our tests, we will be using a test rig which is comprised of the ASRock Z890 Taichi motherboard, along with an Intel Core Ultra 9 285K @ default speed, and a GeForce RTX 4080 Super.
Although the motherboard was able to support both EXPO and XMPO memory modules, at the time of testing we didn’t have any EXPO memory on hand, so we decided to use XMP memory for our test. We used 48GB of Kingston Fury Renegade DDR5-8800 CUDIMM at default XMP Profile 1.
All tests were conducted at turbo clock speeds at a minimum resolution of 1920×1080 or higher. High or Ultra settings enabled.

AIDA64 Info
CPU-Z Info
CPU-Z indicates that the Core Ultra 9 285K is manufactured using a “7nm” process, but according to Intel, the CPU Lithography uses TSMC’s N3B (3nm) node.
Load Temps
Using the Thermaltake 360 Ultra AIO cooler mounted with 3 x Corsair RX120 RGB cooling fans, the processor produced a full load temperature of only 72 degrees Celsius for the CPU, and 91 degrees Celsius for the CPU package. It’s the lowest we’ve seen for an Intel processor. It’s much lower than I expected considering the TDP of the Core Ultra 9 285K is rated at 125W.
In any case, it’s always good to get yourself a good 360mm AIO Liquid cooler, if you plan to build a system with the Intel Core Ultra (Series 2) Processors.
