Intel Nova Lake-S Could Bring 52-Core Desktop CPUs And 700W Power Draw

Intel plans to release Nova Lake-S desktop CPUs in two main variants, according to Wccftech. The single compute tile version will scale up to 28 cores, while the dual compute tile model could reach an eye-catching 52 cores.

These chips will debut Intel’s in-house big bLLC cache design. Cache capacity may climb to 144 MB on single tile models and up to 288 MB on dual tile configurations, pushing desktop cache sizes into workstation-class territory.

Power consumption reportedly exceeds 700W

Well-known insider Kopite7kimi claims that dual compute tile Nova Lake-S CPUs show extremely high power consumption under full load. The top Nova Lake-K model allegedly exceeds 700W when fully saturated.

For context, Intel’s current flagship Arrow Lake Core Ultra 9 285K typically reaches around 370–400W when fully unlocked during stress tests. The jump aligns with Nova Lake’s more than doubled core count and massive cache expansion.

Because of this, sources suggest treating dual compute tile Nova Lake CPUs more like HEDT-class products rather than standard mainstream desktop chips.

Thermals, cooling, and platform details

Jaykihn previously reported early thermal behavior details for Nova Lake-S. Temperature sensors reportedly support readings from -64 °C to 100 °C, with negative temperature reporting enabled. Intel does not support TJMax offsets or disabling thermal throttling, so cooling will directly affect sustained performance.

Despite the changes, Nova Lake-S package dimensions remain the same as Arrow Lake, meaning existing coolers should fit mechanically. However, new IHS offset tuning may become necessary to achieve optimal cooling results.

Each 8+16 compute tile measures roughly 94 mm², placing dual tile CPUs near 190 mm² total die area. Intel expects Nova Lake-S CPUs and 900-series motherboards to launch later in 2026.

In other Intel news, reports suggest the company has canceled the Core Ultra 9 290K Plus, while upcoming Core G3 chips reportedly rely on LPDDR5X-8533 memory. Also, the specs for the new Intel 900 chipset line have leaked.
