Intel Nova Lake-S Leak Points to a 28-Core Desktop CPU With a Massive 296W PL1 Power Limit
Intel’s next-generation Nova Lake-S desktop processors are starting to look far more aggressive than earlier expectations suggested. A new leak claims that one of the upcoming 28-core Nova Lake-S chips could carry a PL1 power limit of 296W, making it a potentially extreme option for high-end desktop users, gamers, and creators who want maximum performance.
The rumored processor is said to use an 8+16+4 core layout. That means it may feature 8 performance cores, 16 efficiency cores, and 4 low-power efficiency cores, bringing the total to 28 cores. This configuration has appeared in previous leaks as part of Intel’s single-compute-tile Nova Lake-S family, and it could be paired with Intel’s new bLLC, or Big Last-Level Cache, technology.
The most attention-grabbing detail is the reported 296W PL1 figure. PL1 usually refers to the sustained power limit of a processor, while TDP is a more general thermal design rating. Earlier leaks suggested this 28-core bLLC model could have a 125W TDP, while higher-tier enthusiast Nova Lake-S chips might sit around 175W. If the 296W PL1 rumor is accurate, Intel may be preparing to push sustained power much higher in order to unlock stronger multi-core and gaming performance.
The leaked 28-core Nova Lake-S CPU is also expected to include 144 MB of bLLC cache, in addition to the cache already available from the CPU cores themselves. This larger cache design is believed to be Intel’s answer to AMD’s 3D V-Cache strategy, which has proven especially effective in gaming workloads. A bigger last-level cache can help reduce memory latency and keep more data closer to the CPU cores, potentially improving performance in games, simulations, rendering tasks, and other demanding applications.
Intel’s Nova Lake-S lineup is expected to include several desktop chip configurations. Current rumors point to single-tile models with 4 performance cores and no efficiency cores, 4 performance cores with 8 efficiency cores, and 8 performance cores with 16 efficiency cores. Some versions may use standard cache layouts, while others could include the larger bLLC design. At the top end, Intel is also rumored to be preparing dual-compute-tile models with as many as 52 cores and up to 288 MB of cache.
One of the notable details across these rumored Nova Lake-S desktop processors is support for 24 PCIe Gen 5 lanes and integrated graphics based on Intel’s Xe3 architecture with 2 GPU cores. While these specifications are still unconfirmed, they suggest Intel is designing Nova Lake-S as a broad desktop platform that can scale from mainstream builds to enthusiast-class systems.
Power consumption could become one of the biggest talking points for this generation. Some larger Nova Lake-S chips have been rumored to reach PL2 limits as high as 474W, although those figures are reportedly tied to bigger dual-tile processors. Still, a 296W PL1 on a single-tile 28-core CPU would be a major jump and could place serious demands on motherboard power delivery and CPU cooling.
If these leaks prove accurate, high-end Nova Lake-S systems may require premium cooling solutions, such as large liquid coolers or advanced custom cooling setups, especially for users who plan to run heavy workloads for long periods. Enthusiast motherboards with strong VRM designs will also likely be important for maintaining stable performance under sustained loads.
Intel appears to be taking a bold approach with Nova Lake-S. Instead of focusing only on efficiency, the company may be targeting maximum desktop performance through higher core counts, larger cache, and more aggressive power limits. For gamers, the addition of bLLC could be especially important, while productivity users may benefit from the 28-core design in rendering, encoding, compiling, and content creation workloads.
As with all early leaks, these details should be treated as unofficial until Intel provides final specifications. However, the rumored 28-core Nova Lake-S CPU with 144 MB of bLLC and a 296W PL1 limit is already shaping up to be one of the most interesting desktop processor stories to watch. If the performance matches the power budget, Intel’s next-generation desktop lineup could deliver a major leap for enthusiast PCs.
