The mysterious Intel Core Ultra 7 254V has surfaced in leaked PassMark benchmarks, and its performance is already raising eyebrows. 
While Intel hasn’t officially acknowledged this chip in its Lunar Lake lineup, the benchmark suggests it exists-and it might be a cut-down variant of the Ultra 7 256V.
On paper, the 254V matches the rest of the series with 8 cores and 8 threads, along with 12 MB of L3 cache. Single-core results are surprisingly solid: it even edges out the 256V and 258V by roughly 1% with a score of 4,089. But the story changes dramatically in multi-threaded workloads
. The 254V trails its bigger siblings by nearly 13% compared to the 256V and around 9.5% against the 258V. More shockingly, it posts weaker results than the entry-level Ultra 5 226V, making it the only Lunar Lake CPU to fall below 18,000 in multi-core tests.
That gap suggests either much lower clock speeds or another hidden limitation, though nothing concrete is confirmed. Power ratings appear to align with the 17W PL1 and 37W turbo envelope seen across the family. Still, the chip’s existence raises questions: is this simply a recycled die, a binned-down part to fill a supply gap, or a specialized SKU aimed at handhelds and compact mini PCs where thermals matter more than raw throughput?
For now, the Ultra 7 254V remains a mystery-an unannounced processor that performs like an Ultra 7 in name but sometimes less than an Ultra 5 in practice. Until Intel formally reveals its purpose, the chip feels like an odd puzzle piece in the Lunar Lake family.
