7/29/2025Intel Nova Lake with bLLC: The Complete Guide to Intel's AMD 3D V-Cache Rival Coming in 2026
Intel Nova Lake bLLC (Big Last Level Cache) aims to rival AMD's 3D V-Cache with up to 144MB L3 cache in 2026. Complete specs, performance expectations, and release timeline.
Intel's struggle to regain gaming performance leadership has reached a critical juncture. After the disappointing gaming performance of Arrow Lake and ongoing Raptor Lake stability issues, Intel is preparing its most ambitious response yet: Nova Lake processors featuring bLLC (Big Last Level Cache) technology. This revolutionary cache architecture represents Intel's direct answer to AMD's dominant 3D V-Cache, promising to transform gaming performance when it launches in 2026.
The Nova Lake bLLC implementation could fundamentally change Intel's competitive position in the gaming CPU market, offering the massive cache sizes that have made AMD's X3D processors the undisputed champions of gaming performance since 2022.
Understanding bLLC: Intel's Big Last Level Cache Technology
The bLLC (Big Last Level Cache) represents a paradigm shift in Intel's approach to cache architecture. The extra cache, dubbed bLLC (or big Last Level Cache) will apparently behave similarly to AMD's 3D V-Cache, and be an extra block of cache separate from the integrated (regular) L3 cache attached to each core.
Technical Architecture Behind bLLC
Unlike traditional cache implementations, Intel's bLLC technology takes inspiration from server-grade architectures. The bLLC technology already exists in Intel's Clearwater Forest server CPUs. In those chips, the cache is embedded in a base tile underneath the core tiles, which helps improve performance without causing the heat and clock speed issues that come from stacking cache on top of cores.
This base tile approach offers significant advantages over AMD's stacked 3D V-Cache design:
Thermal Management: By placing the large cache underneath the core tiles rather than on top, Intel avoids the thermal constraints that limit AMD's X3D processors' maximum clock speeds.
Manufacturing Flexibility: The base tile design allows Intel to scale cache sizes more easily and potentially offer different cache configurations across various SKUs.
Power Efficiency: The architectural separation could enable more sophisticated power management, allowing the cache to operate independently of the processing cores.
Cache Size Specifications
Early leaks suggest impressive cache sizes for Nova Lake bLLC implementations. Intel's upcoming Nova Lake CPUs may include a massive 144 MB L3 cache (bLLC) to improve gaming performance and take on AMD's 3D V‑Cache. This would represent a substantial increase over current Intel processors and potentially match or exceed AMD's largest 3D V-Cache implementations.
The 144MB figure, if accurate, would position Nova Lake as having some of the largest consumer CPU cache pools ever implemented, providing substantial benefits for gaming workloads that rely heavily on cache performance.
Nova Lake Processor Specifications and Configurations
Intel's Nova Lake lineup will feature a hybrid architecture similar to current Core Ultra processors, but with significant enhancements in core count and cache implementation.
Core Configurations with bLLC
According to recent leaks, The new processors with bLLC will have 8 P-cores and 4 LP-E-Cores. One version will include 20 E-cores, while another will have 12 E-cores. More specifically, both chips will feature a 125W TDP, eight performance cores, four low-power efficient cores, differing only in their efficient core count at 16 and 12 a piece.
