Intel Core Ultra 9 290K Plus Ends Up 10% Faster In ST & 11% Faster In MT Versus 285K In Latest Leak

Intel’s Core Ultra 9 290K Plus CPU has leaked out once again, and delivers up to a 11% performance boost over the 285K.

Intel Core Ultra 9 290K Plus Is Up To 11% Faster Than Core Ultra 9 285K In Latest Leak

The Intel Core Ultra 9 290K Plus will be the flagship chip within the Core Ultra 200S Plus “Arrow Lake Refresh” family. This chip is expected to retain the same configuration unless the blue team suddenly comes out with a new Arrow Lake-S die, which remains highly unlikely. So we can expect the CPU to offer the same 24 cores, 24 threads, but with higher clock speeds and possibly a higher TDP too.

The latest tests were carried out on the ASUS ROG STRIX Z890-E Gaming WIFI motherboard with 64 GB of DDR5-6800 memory.

As for the performance, the Intel Core Ultra 9 290K PLUS CPU scored 3535 points in the single-thread test and 25,106 points in the multi-core tests. When compared to the Core Ultra 9 285K, this is a 10% uplift in single-core and 11% improvement in multi-core tasks. This is a nice improvement versus the previous 7% and 9% gains. When compared to AMD’s fastest chip, the Ryzen 9 9950X3D, the 290K PLUS offers a 4% improvement in single-core and a 13% improvement in multi-core tasks.

The following is how the performance stacks up:

Now we don’t expect the gaming performance of the 290K Plus to be much different than the existing 285K, and AMD’s 3D V-Cache chips are going to retain their phenomenal lead.

The lineup looks a lot like a last effort to clear some additional 800-series motherboard inventory before the launch of the next-gen Nova Lake-S platform, which will feature a brand new socket, “LGA 1954”. Expect more leaks and details of the lineup in the coming months as we approach the launch.
