Intel’s next-generation desktop processors won’t arrive for a while, but a fresh leak is already stirring excitement: new Nova Lake-S chips could deliver a huge boost to gaming performance through a large on-package cache, directly targeting AMD’s popular 3D V-Cache technology.

According to a since-deleted post by hardware leaker @OneRaichu on X (formerly Twitter), Intel is readying at least two Nova Lake-S SKUs in the Core Ultra 400 series that combine an unusual 22-core configuration with something described as “bLLC,” short for big Last Level Cache. The leak doesn’t name the exact Core Ultra 5 model, but the midrange branding fits the core count and positions the chip as a direct answer to AMD’s best-selling Ryzen 7 7800X3D and 9800X3D.

If the details are accurate, this would mark the first time Intel has brought a genuinely large, gaming-focused cache to its mainstream desktop lineup since the Broadwell days nearly a decade ago. The move could reshape which processor gamers and creators choose for their next PC.

A 22-Core Hybrid Puzzle: Big.Little Gets an Upgrade

The leaked configuration is unlike anything Intel has shipped for desktops before. Each chip reportedly packs 6 Performance-cores (P-cores) with Hyper-Threading, 12 Efficient-cores (E-cores), and 4 Low-Power Efficient-cores (LP E-cores). That’s 6 + 12 + 4 = 22 physical cores, yielding a total of 28 threads (6x2 + 12 + 4).

Intel already uses LP E-cores in its Meteor Lake laptop processors to handle background tasks and boost idle efficiency, but bringing them to desktop is a new twist. On a tower PC plugged into the wall, the power savings might seem irrelevant, but they could help the chip sip watts during light loads and allow the main P- and E-cores to clock higher under heavy gaming or rendering workloads.

This three-tier hybrid design suggests Nova Lake-S is built from the same tile-based playbook as Lunar Lake and Arrow Lake. The compute tile might be manufactured on Intel’s upcoming 18A process node, while the cache tile—likely the home of that mysterious bLLC—could be on a different manufacturing process entirely.

For comparison, Intel’s current flagship, the Core Ultra 9 285K (Arrow Lake), uses 8 P-cores and 16 E-cores but drops Hyper-Threading, capping at 24 threads. The rumored Core Ultra 5 would therefore offer more total threads (28) despite having fewer P-cores, potentially improving multi-threaded grunt for content creation and multitasking. However, the 6+12+4 layout puts it squarely in the midrange, not the high-end Core Ultra 9 or 7 tier.

Why bLLC Matters: The Cache That Could Close the Gap

The biggest news here is the “bLLC” label, which stands for big Last Level Cache. In a modern CPU, the last-level cache (usually L3) acts as a high-speed pool of memory sitting between the cores and system RAM. The larger this cache, the fewer times the processor has to fetch data from slower DRAM, which directly improves frame rates in many games.

AMD’s 3D V-Cache technology stacks an extra slab of L3 cache on top of the CPU die, effectively tripling the L3 available to gaming workloads. The result has been spectacular: the Ryzen 7 7800X3D, with 96MB of L3 cache, often beats far more expensive Intel chips in gaming benchmarks, especially at 1080p and 1440p resolutions where the CPU is the limiting factor.

Intel has tried a large cache only rarely and long ago. The Core i7-5775C (Broadwell) from 2015 included 128MB of embedded DRAM acting as an L4 cache, and it punched above its weight in titles that loved low latency. Since then, Intel has relied on raw clock speed and IPC improvements, while AMD walked away with the gaming crown.

The bLLC in Nova Lake-S might be a separate tile on the package, sharing the interposer with the compute and graphics tiles. It could function as a large L3 or even an L4 cache, visible to the OS and automatically leveraged by the Thread Director—Intel’s hardware scheduler that steers workloads to the best core type. If the cache is massive enough, it could dramatically slash memory latency and let the 6 P-cores challenge AMD’s X3D parts in gaming.

Leaked details don’t specify the cache size, but expect it to be at least 64MB or more to earn the “big” moniker. For context, the Arrow Lake Core Ultra 200S series tops out at 36MB of L3 cache. Doubling or tripling that figure would put Intel right in X3D territory.

What This Means for Your Next PC Build

The rumored Core Ultra 5 with bLLC would land squarely in the sub-$350 price band, traditionally the sweet spot for mainstream gaming rigs. That makes the leak especially significant for three groups of buyers.

Gamers stand to gain the most. A midrange chip that can match or exceed today’s X3D gaming performance would upend the market. You’d be able to build a high-refresh-rate 1080p or 1440p gaming PC without spending $450 or more on a CPU, freeing budget for a better GPU. If Intel also maintains its traditionally strong multi-core advantage, the Core Ultra 5 could become the go-to recommendation for gaming plus streaming.

Content creators and multitaskers should pay attention to the core count. With 28 threads, this chip would out-muscle the Ryzen 7 7800X3D (8 cores, 16 threads) in heavily threaded applications like video rendering, code compilation, and 3D modeling. The large cache may also accelerate certain creative workloads, especially those with large datasets. It won’t beat a 16-core monster, but it could deliver excellent all-rounder performance at a much lower price.

General users and office workers won’t see a meaningful day-to-day benefit from the bLLC cache. Email, web browsing, and Office apps are unlikely to notice the difference. If your current PC still feels snappy, waiting another year or two is perfectly fine. However, if you’re already considering a new build for moderate gaming or casual creation, this leak suggests patience could pay off.

There’s a critical platform catch: Nova Lake-S will almost certainly use a new CPU socket. Intel has historically supported a socket for two generations before moving on; LGA 1700 carried Alder Lake, Raptor Lake, and Raptor Lake Refresh, while LGA 1851 debuted with Arrow Lake and is expected to die with that generation. A Nova Lake desktop chip would logically usher in a new, incompatible socket—meaning you’ll need a new motherboard and likely new DDR5 memory (though existing kits should work, speeds may advance). Budget for a full platform upgrade.

How We Got Here: The Long Road to a Competitive Intel Cache

Intel’s history with large caches is a story of false starts and missed opportunities. The Broadwell desktop chips (Core i7-5775C, i5-5675C) in 2015 packed 128MB of eDRAM that served as a huge L4 cache, giving them surprise gaming wins against newer Skylake parts that lacked the extra cache. But the technology was expensive, and Intel never brought it to the high-volume Core i5 and i7 chips that followed.

Fast-forward to 2021, and AMD caught the industry off guard with the Ryzen 7 5800X3D—the first consumer chip with 3D V-Cache. By stacking an additional 64MB of L3 cache on top of a standard 8-core CCD, AMD boosted gaming performance by 15–20% on average, instantly creating a new performance tier. Subsequent X3D parts (7800X3D, 7950X3D, 9800X3D) widened the gap, and Intel’s 12th, 13th, and 14th Gen chips could only fight back with higher power and clocks.

Arrow Lake (Core Ultra 200S) improved power efficiency and single-thread IPC but stayed with a modest 36MB of L3. The gaming performance was solid but couldn’t leapfrog AMD’s best. Now, with Nova Lake-S, Intel appears ready to embrace the cache arms race—and the timing couldn’t be better. AMD has already hinted at a second-generation 3D V-Cache that could stack even more cache, so Intel needs more than just IPC bumps to stay in the game.

The bLLC approach is likely a direct descendant of Intel’s server-grade cache technologies. The company has experimented with HBM memory as a cache on Xeon Max CPUs, and its multi-tile designs already separate the compute, graphics, and I/O functions. Adding a dedicated cache tile is a logical extension that could be tuned for consumer workloads—especially gaming.

What You Should Do Right Now (and What to Ignore)

First, treat all of this as speculation until Intel confirms it. Leaks are frequently inaccurate; core counts, cache sizes, and even product names can shift as launch windows slip. That said, the information lines up well with Intel’s known roadmap, and @OneRaichu has a decent track record on CPU leaks.

Here’s your practical upgrade roadmap:

  • If you need a PC today, buy today. The current market offers excellent options: Intel’s Core Ultra 200S series delivers strong multi-core performance and efficiency, while AMD’s Ryzen 7000/9000 X3D chips are the reigning gaming champions. You’ll get a fantastic experience without waiting an indeterminate amount of time.
  • If you can wait 12–18 months, start earmarking funds for a Nova Lake build. The CPU itself is unlikely to be cheap at launch, and you’ll need a new motherboard. Aim for a budget of $600–$800 for CPU plus board, assuming midrange pricing.
  • Don’t base a platform purchase on rumors. Avoid buying an LGA 1851 motherboard now if you hope to drop in a Nova Lake chip later—it almost certainly won’t be pin-compatible. If you go Intel today, expect to replace the board when you upgrade the CPU.
  • Ignore hyperbolic claims. Until independent reviewers test real silicon, no one can promise “game-changing” performance. Even if the bLLC is real, its impact will depend on the specific games and applications you run.

Keep an eye on Intel’s event calendar. The company’s annual Innovation conference (typically in September) and its CES keynote in January are the most likely venues for official Nova Lake teasers or architectural disclosures.

Outlook: A Midrange Shake-Up Is on the Horizon

Nova Lake-S with bLLC cache has the potential to reignite the desktop CPU rivalry in the most important price band. If Intel can deliver X3D-like gaming performance from a Core Ultra 5 priced under $350, it would force AMD to respond—either by dropping prices or accelerating its own 3D V-Cache roadmap.

Yet execution remains everything. Intel has had a rocky few years with chip delays and product cancellations. Nova Lake must launch on time, on a healthy 18A process, and with enough volume to actually reach store shelves. The company’s recent restructuring and foundry challenges add uncertainty, but the technical direction appears sound.

For now, the leak serves as an exciting preview of what desktop computing might look like in late 2025 or early 2026. Competition between Intel and AMD has rarely been this intense, and that’s a win for anyone planning their next PC build.
