Intel’s next desktop update is shaping up to be a meaningful one for people who care more about productivity performance than flashy marketing. A new chip called the Intel Core Ultra 5 250K Plus, part of the upcoming “Arrow Lake Refresh” family, is expected to launch soon as the successor to the Core Ultra 5 245K. And if early database results are any indication, the upgrade isn’t just a minor bump—it could be a solid step forward for heavy multitasking and multi-threaded workloads.
The Core Ultra 5 245K currently features a 14-core configuration, but the Core Ultra 5 250K Plus is expected to move to an 18-core design made up of 6 performance cores (P-cores) and 12 efficiency cores (E-cores). That’s four extra E-cores compared to its predecessor, which is exactly the sort of change that can lift performance in tasks that scale across many threads—think content creation, code compilation, productivity suites, and CPU-heavy background workloads.
A previous early listing for the chip suggested similar single-core results and surprisingly weak multi-core performance, which raised eyebrows. That earlier showing now looks more like a very early sample that wasn’t running at its intended clocks or limits. The more recent appearance in PassMark paints a far more convincing picture of what this CPU is meant to do.
According to the PassMark results, the Core Ultra 5 250K Plus only improves single-thread performance by about 2.1% over the Core Ultra 5 245K. That modest gain makes sense—single-core improvements often come down to clock speed, cache behavior, and small architectural tuning, and refresh generations typically don’t transform single-thread speed overnight.
Where things get interesting is multi-core performance. The PassMark multi-thread result is listed at roughly 16.3% faster than the Core Ultra 5 245K. That’s a big jump for a refresh, and it strongly suggests those additional E-cores are doing real work—especially when paired with slightly higher boost clocks, reportedly around 100 MHz faster on both P-core and E-core turbo frequencies.
The comparison against AMD’s Ryzen 5 9600X is even more dramatic in multi-threaded performance. In the same PassMark-style multi-thread test, the Core Ultra 5 250K Plus is shown as more than 66% faster, while single-core is only about 4% ahead. That gap highlights an important reality for buyers: these CPUs can target different strengths. The Ryzen 5 9600X has been known as a strong gaming-oriented option, and it may still keep an advantage in gaming even if the Intel chip wins decisively in productivity and multi-threaded scenarios.
The Core Ultra 5 250K Plus isn’t the only “Arrow Lake Refresh” processor expected. The lineup is also said to include the Core Ultra 7 270K Plus, which should follow a similar idea—adding four more E-cores and pushing higher turbo clocks. Meanwhile, the higher-tier Core Ultra 9 290K Plus is reportedly cancelled due to product overlap, suggesting Intel is focusing the refresh on the segments where the upgrade story is clearest.
If these early numbers hold up in broader testing, the Intel Core Ultra 5 250K Plus could end up being an appealing choice for buyers seeking a desktop CPU that excels at demanding productivity tasks without jumping to a far more expensive tier. For anyone who routinely pushes multi-core workloads—while still wanting strong everyday responsiveness—this is one processor worth watching as launch details firm up.
