Intel’s unreleased Core i9-14901KE has surfaced in qualification-sample testing, revealing an unusual Raptor Lake Refresh design: eight Performance cores, no Efficient cores, and an unlocked multiplier. The chip reportedly reached 7.4GHz under cascade cooling, but the results suggest it offered no exceptional overclocking advantage over conventional Raptor Lake silicon.
VideoCardz first highlighted testing from Bilibili creator WestmereX, while Club386 independently detailed the benchmarks. The Core i9-14901KE appears to have been an embedded-market processor that Intel developed to a late stage before removing it from its product catalogue; there is no confirmed retail release or announced system using it.
At stock settings, the 8-core/16-thread CPU is configured for a 3.8GHz base clock, 5.8GHz boost clock, 36MB cache and 125W processor base power. That makes it effectively comparable to a Core i9-14900K with its 16 E-cores disabled, rather than a new architectural direction for desktop enthusiasts.

The unusual part is not merely the missing E-cores. Intel already sells several 14th-generation embedded parts with P-Core-only layouts, including the Core i9-14901E and Core i9-14901TE. The 14901KE, however, reportedly retained an unlocked multiplier, making it a conspicuous experiment in pairing embedded positioning with enthusiast-style tuning.
WestmereX’s Q49D sample ran Cinebench R23 at 5.5GHz across all eight P-cores, consuming roughly 190W at 1.225V. Raising the all-core clock to 5.8GHz pushed power consumption to about 269W, for a multi-threaded gain of less than 6 percent. That is a familiar Raptor Lake trade-off: substantially more power for increasingly modest performance returns.

7.4GHz Is a Showcase Result, Not a Practical Target​

The reported 7.4GHz stable frequency required a cascade cooling setup operating around minus 100°C. The same test system completed SuperPI 1M at 6.9GHz with DDR5-8120 CL30 memory, an impressive validation result but not one relevant to air- or liquid-cooled PCs.
More importantly, VideoCardz concluded that removing E-cores did not unlock a special frequency ceiling. The engineering sample’s results were broadly in line with other sub-zero Raptor Lake overclocking demonstrations, undercutting the idea that E-cores themselves were the defining barrier to extreme clocks.

What It Means for PC Builders​

For Windows PC users, this is a look at an abandoned product branch rather than a newly available upgrade option. A P-Core-only Core i9 could have appealed to niche workloads sensitive to hybrid scheduling behavior, but Windows 11’s Thread Director-aware scheduling and modern application support have made that argument less compelling than it was at the start of Intel’s hybrid-core transition.
The more durable takeaway is that Intel apparently considered an unlocked, P-Core-only 14th-generation SKU and ultimately did not bring it to market. The 14901KE sample demonstrates that the design was real; its benchmark results explain why it may not have justified a separate product line.
