Intel's Core Ultra 9 285K flagship CPU along with the Core Ultra 7 265K and Core Ultra 5 245K have been tested in various benchmarks.
Intel Core Ultra 9 285K CPU achieves up to 19% performance over 14900K in Blender Benchmark, Core Ultra 7 265K & Core Ultra 5 245K Tested Too
Intel revealed its latest Core Ultra 200 Series aka Arrow Lake processors on 10th October, which comprises five SKUs for the initial launch. The Core Ultra 9 285K is the fastest in the series, featuring 24 cores/24 threads, challenging the current flagship Core i9 14900K from the Raptor Lake Refresh family.
The processor was recently benchmarked in two different programs, showing some good scores in the multi-threaded benchmarks but had some issues. As spotted by @momomo_us, reviewers are now Benchmarking the Core Ultra 9 285K in CPU-Z, using the ASRock Z890 Steel Legend WiFi. It's not clear what CPU cooler was used but looks like it wasn't enough to cool down this beast.
From the results, we can see that the Intel Core Ultra 9 285K achieved an impressive 18964 points in multi-threaded performance, which outperforms all the previous flagship mainstream Intel Core i9 processors. However, the single-core score maxed at 909 points, which is still behind many Core i9s from both Raptor Lake and Raptor Lake Refresh families.
CPU-z (Higher is Better)
Nonetheless, what we see is that the CPU reached a whopping 101°C, which is pretty close to its maximum operating temperature limit of 105°C. This looks like a clear case of thermal throttling, which affects the performance. The CPU did reach its max P-Core and E-Core boost clocks of 5.5 GHz and 4.6 GHz respectively but at this temperature, it's hard to sustain these clock speeds for long.
One more thing to notice from the details page is that the Uncore or Ring Bus clock is mentioned as 3790.9 MHz, which is reportedly 700 MHz lower than the Core i9 14900K. This is why some leaks report little improvements in gaming performance.
The Intel Core Ultra 9 285K CPU was also benchmarked in Blender v4.2(via @9550pro) and scored 557.46 points. This initial test is much better than the performance of Core i9 14900K, which scored 475.97 points but it still loses to Ryzen 9 9950X, which scored 598.7 points.
The Intel Core Ultra 9 285K, Core Ultra 7 265K & Core Ultra 5 245K have also been tested in Blender. The Core Ultra 9 285K scored 566.88 points while the Core Ultra 7 265K scored 471.21 points and the Core Ultra 5 245K scored 323.46 points.

We don't know the motherboard used or any information about the configurations in both cases. So, it can be a bit early to tell if this is the true performance of both chips. We are one week away from the official (24th October) launch and it's expected that we may see more such performance numbers of Arrow Lake chips.
