Intel's Nova Lake-S CPUs Rumored to Feature Massive 144MB Cache to Counter AMD
Tuesday, November 25, 2025Intel's Nova Lake-S CPUs Rumored to Feature Massive 144MB Cache to Counter AMD
Intel is reportedly preparing a bold response to AMD's 3D V-Cache technology with its upcoming Core Ultra 400 series, potentially featuring up to 144MB of big last level cache (bLLC) on high-end models.
The battle for CPU supremacy is heating up as new leaks suggest Intel's Nova Lake-S architecture will introduce a substantial cache increase, directly targeting AMD's gaming performance advantage. This move comes as AMD's X3D CPUs have consistently outperformed Intel's flagship processors in gaming scenarios despite often lower price points.
The Cache War: Intel vs AMD
The introduction of bLLC (Big Last Level Cache) represents Intel's long-awaited answer to AMD's successful 3D V-Cache technology. AMD has leveraged this advantage since the Ryzen 5000 series, creating significant headaches for Intel's marketing teams as their sub-$500 CPUs easily outperform Intel's flagship SKUs in gaming.
According to leaks from reliable source Jaykihn, Intel's upcoming Core Ultra 400K processor will feature a single 144MB bLLC cache integrated into the compute tile. This substantial cache size would mark a significant departure from Intel's traditional designs and directly compete with AMD's cache-focused approach.
Comparative Cache Sizes
The following table illustrates how Intel's rumored bLLC implementation compares to AMD's existing 3D V-Cache technology:
| CPU Series | Base L3 Cache | Additional Cache | Total Cache |
|---|---|---|---|
| Ryzen 5000X3D | 32MB | 64MB | 96MB |
| Ryzen 7000X3D | 32MB | 64MB | 96MB |
| Ryzen 9000X3D | 32MB | 64MB | 96MB |
| Ryzen 10000X3D (Rumored) | 48MB | 96MB | 144MB |
| Core Ultra 400K (Rumored) | - | 144MB | 144MB |

Technical Implications and Platform Details
The rumored Nova Lake-S platform represents a significant architectural shift for Intel. According to leaks, these processors will feature a hybrid configuration with up to 52 cores (16 Performance-cores + 32 Efficient-cores + 4 Low-power Efficient-cores) and will utilize a new LGA-1954 socket.
The bLLC cache is said to be part of the compute tile, which suggests a fundamental redesign of Intel's chip architecture. Previous rumors even mentioned the possibility of a dual bLLC variant, though current information suggests only single bLLC configurations are in development.
The following table provides an overview of Intel's desktop platform evolution based on current rumors:
| Platform | Codename | Socket | CPU Cores | GPU | NPU | BLLC |
|---|---|---|---|---|---|---|
| 12th Gen Core | Alder Lake-S | LGA-1700 | 16 (8P + 8E) | Xe-LP | ❌ | ❌ |
| 13th Gen Core | Raptor Lake-S | LGA-1700 | 24 (8P + 16E) | Xe-LP | ❌ | ❌ |
| 14th Gen Core | Raptor Lake-S Refresh | LGA-1700 | 24 (8P + 16E) | Xe-LP | ❌ | ❌ |
| Core (Ultra) 200 | Arrow Lake-S | LGA-1851 | 24 (8P + 16E) | Xe-LPG | NPU3 | ❌ |
| Core (Ultra) 200 Refresh | Arrow Lake-S Refresh | LGA-1851 | 24 (8P + 16E) | Xe-LPG | NPU3 | ❌ |
| Core (Ultra) 400 | Nova Lake-S | LGA-1954 | 52 (16P + 32E + 4 LP-E) | Xe3(p)-LPG | NPU6 | ✅ |

Market Impact and Availability
While Intel is currently preparing to introduce a refresh of Arrow Lake (Core Ultra 200 series), the industry is already looking ahead to its successor. The Nova Lake-S processors, potentially arriving as the Core Ultra 400 series nearly a year after Panther Lake, would represent Intel's most significant architectural shift in recent years.
The addition of substantial cache could help Intel close the gaming performance gap that has allowed AMD to dominate in this crucial market segment. However, as with all rumors, these specifications should be treated with caution until official confirmation from Intel.
