Intel Nova Lake-S Core Ultra 9 4950K Specs Revised in Leak
A new leak has reportedly provided additional details about Intel’s upcoming Nova Lake-S desktop processor family, including a revised configuration for the Core Ultra 9 4950K.
The leaked lineup points toward a possible four-digit Core Ultra 4000-series naming scheme covering Core Ultra 9, Core Ultra 7, and Core Ultra 5 processors.
At the top of the reported stack is the Core Ultra 9 4970K BFC, which is listed with 28 cores and Intel’s bLLC (Big Last Level Cache) technology. Meanwhile, the latest information reportedly reduces the previously leaked Core Ultra 9 4950K from 28 cores to 24 cores.
Intel has not officially confirmed these products or specifications, so the information should be treated as preliminary.
🧩 Leaked Nova Lake-S Lineup Shows Clear SKU Segmentation #
The latest details, reportedly first shared by @laurentschoice and subsequently cross-checked by VideoCardz, describe seven Nova Lake-S models spanning several performance tiers.
| Model | Reported CPU Configuration | bLLC | Reported TDP |
|---|---|---|---|
| Core Ultra 9 4970K BFC | 8 P + 16 E + 4 LP-E = 28 cores | Yes | 125W |
| Core Ultra 9 4950K | 8 P + 16 E = 24 cores | No | — |
| Core Ultra 9 4900 BFC | 22 cores | Yes | 65W |
| Core Ultra 7 4870K BFC | 24 cores | Yes | — |
| Core Ultra 7 4850K | 20 cores | No | — |
| Core Ultra 5 4650K | Not fully disclosed | — | — |
| Core Ultra 5 4650KF | Not fully disclosed | — | — |
The leaked configurations suggest Intel may be using both core count and cache capacity to differentiate Nova Lake-S products.
Core Ultra 9 4970K BFC #
The reported flagship is the Core Ultra 9 4970K BFC, featuring:
- 8 P-cores.
- 16 E-cores.
- 4 LP-E cores.
- 28 cores in total.
- bLLC.
- 125W reported TDP.
- 32-EU integrated GPU.
The inclusion of four LP-E cores distinguishes this configuration from the reported 4950K.
Core Ultra 9 4950K #
The revised Core Ultra 9 4950K is now listed with:
- 8 P-cores.
- 16 E-cores.
- 24 cores in total.
- No reported LP-E cores.
- No bLLC.
This makes the 4950K substantially different from the flagship despite both belonging to the Core Ultra 9 tier.
💾 BFC Appears to Identify Intel’s Large-Cache Models #
One of the clearest patterns in the leak is the reported BFC suffix.
The three leaked models carrying this designation are:
- Core Ultra 9 4970K BFC.
- Core Ultra 9 4900 BFC.
- Core Ultra 7 4870K BFC.
All three are reportedly equipped with bLLC, while the standard models in the leaked lineup do not include the technology.
bLLC Adds Another Layer of Product Segmentation #
Intel’s reported Big Last Level Cache approach would give Nova Lake-S another way to differentiate processors beyond conventional core counts and clock speeds.
Large cache configurations can be particularly useful for workloads that repeatedly access relatively small working sets, potentially reducing the frequency with which data has to be retrieved from system memory.
The positioning also appears relevant to gaming, where AMD’s 3D V-Cache has made large CPU cache an important differentiating feature.
However, the actual size, implementation, latency characteristics, and performance impact of Nova Lake-S bLLC remain unconfirmed.
🔄 Core Ultra 9 4950K Drops From 28 to 24 Cores in Latest Leak #
The biggest change compared with earlier reports concerns the 4950K.
Earlier 28-Core Configuration #
An earlier CPU-Z leak from August reportedly identified the Core Ultra 9 4950K as a 28-core processor.
That configuration would have placed it much closer to the reported flagship in terms of total core count.
Latest 24-Core Configuration #
The latest information instead lists the processor as:
8 P-cores + 16 E-cores = 24 cores
The four LP-E cores associated with the 4970K BFC are absent, as is the reported bLLC cache.
This creates a much clearer distinction between the two Core Ultra 9 models.
The change could reflect normal evolution between engineering samples and later product configurations, although the reason for the revision has not been confirmed by Intel.
🏷️ Core Count and Cache Could Define Nova Lake-S Tiers #
The leaked lineup suggests Intel may be using a combination of architectural resources to create different performance tiers.
The reported hierarchy can be broadly described as:
- Core Ultra 9 4970K BFC — 28 cores, LP-E cores, and bLLC.
- Core Ultra 9 4950K — 24 conventional P/E cores without bLLC.
- Core Ultra 9 4900 BFC — 22 cores with bLLC and a reported 65W TDP.
- Core Ultra 7 4870K BFC — 24 cores with bLLC.
- Core Ultra 7 4850K — 20 cores without bLLC.
- Core Ultra 5 4650K / 4650KF — mainstream models with fewer disclosed details.
This is a leaked product structure rather than a confirmed Intel segmentation strategy, but it indicates that cache technology could become nearly as important as raw core count for distinguishing certain Nova Lake-S processors.
🔍 Intel Has Not Confirmed Nova Lake-S Specifications #
The Nova Lake-S naming convention, individual SKU list, core configurations, bLLC implementation, TDP values, and integrated GPU specifications remain unconfirmed by Intel.
The revised 4950K configuration is particularly notable because it demonstrates how specifications reported from early engineering samples can change as a processor family moves toward final product definition.
For now, the Core Ultra 9 4970K BFC’s reported 28-core design and the Core Ultra 9 4950K’s revised 24-core configuration should be treated as leaked specifications rather than final retail specifications.
Further engineering samples or official Intel disclosures will be needed to establish the final Nova Lake-S lineup.
