Intel Core Ultra 9 285K “Arrow Lake” Flagship Desktop CPU Spotted: ES Chip With 24 Cores, 24 Threads, 76 MB Cache & 5 GHz Clocks

Intel Core Ultra 200 "Arrow Lake" Desktop CPU Specs Leak: Core Ultra 9 285K & Ultra 7 265K With 250W MTP, Ultra 5 245K at 159W 1

Intel's flagship Core Ultra 9 285K "Arrow Lake" Desktop CPU has been spotted with 24 cores and 24 threads in ES state.

Update: The CPU-z screenshot seemingly belongs to a different SKU, not the Core Ultra 9 285K. It might be the Core Ultra 5 245K judging by its lower clock speeds. This is the successor to the Core i5-14600K which boosted up to 5.3 GHz so it's not that big of a clock speed regression.

The Intel Core Ultra 9 285K CPU is going to be the flagship within the Arrow Lake-S Desktop CPU family. This chip is going to replace the Core i9-14900K as the new flagship and it looks like we've our first look at the Core Ultra 200K chips running on an LGA 1851 platform from @wxnod and @9550pro. These leaks come at the same time with one revealing the CPU-z screen while the other shows us the CPU's task manager specs.

Starting with the details, the Intel Core Ultra 9 285K is listed as an Arrow Lake CPU with a 125W TDP which should be the PL1 target. The process node is mentioned as 7nm but that just shows that the version of CPU-z can't identify the technology yet. The CPU itself is supposed to be based on either TSMC's N3B process node or Intel's 20A with the former being the more likely candidate based on reports.

The Intel Core Ultra 200K CPU used here is a QS (Qualification Sample) part and has a listed clock speed of 5.0 GHz. This is the B0 revision and the cache counts are also mentioned.

The specs for the Intel Core Ultra 9 285K are mentioned in the task manager screenshot which reveals 24 cores, and 24 threads so that confirms that we aren't getting hyperthreading on these chips. The cache counts are in line with what was seen a few days ago with 36 MB of L3, 40 MB of L2, and 2.4 MB of L1. That's a total of 76 MB Smart Cache.

Earlier, we had reported a clock speed of up to 5.5 GHz in the ES chips and followed up with the 5.7 GHz clocks reported for the QS chips. With a 5.7 GHz clock, the Intel Core Ultra 9 285K should sit a tad bit behind the Core i9-14900K and Core i9-13900K but considering that this is a brand new CPU architecture and a new node (N3B as rumored), it's a good start for Intel and we can expect further clock speed bumps in refreshes which are already planned for the Arrow Lake lineup. Following is how the clock speeds compare against previous Core i9 releases:

Core Ultra 9 285K - 5.70 GHz (Max)

Core i9-14900KS - 6.20 GHz (Max)

Core i9-14900K - 6.00 GHz (Max)

Core i9-13900KS - 6.00 GHz (Max)

Core i9-13900K - 5.80 GHz (Max)

Core i9-12900KS - 5.50 GHz (Max)

Core i9-12900K - 5.20 GHz (Max)

The Intel Core Ultra 9 285K "Arrow Lake" CPU should be among the launch lineup which is expected in October 2024. These chips will include three unlocked SKUs, the Core Ultra 9 285K, Core Ultra 7 265K, and Core Ultra 5 245K. All three chips will be compatible with the latest Z890 motherboards featuring the LGA 1851 socket.
