Leak claims Intel's Nova Lake-S is up to 20% faster in games
Leaker Haze2K1 puts single-thread gains at 8% without the bLLC cache and 17% with it, and credits Intel's new APX instructions with about 15% of the uplift.
An unconfirmed leak says Intel's Nova Lake-S desktop processors will run games about 20% faster than current Arrow Lake chips. Leaker Haze (@Haze2K1) posted the figures on October 29, 2026, saying they come from "the slides". Intel has not confirmed them, and no official benchmarks exist yet.
The claimed numbers
According to the post, raw single-thread performance improves by about 8% on Nova Lake-S models without Big Last Level Cache (bLLC), and by up to 17% on models that have it. bLLC is Intel's large stacked cache, built to chase the gaming lead AMD holds with 3D V-Cache.
The leak also credits roughly 15% of the gain to APX, Intel's Advanced Performance Extensions. APX doubles the general-purpose registers available to 64-bit code from 16 to 32, which reduces how often the CPU shuffles data in and out of memory. Software has to be built to use it, so the real benefit in games will depend on engine and compiler support rather than arriving automatically on day one.
How it fits earlier leaks
The new figures sit inside the range of an August leak reported by VideoCardz, which described internal projections for a 28-core Nova Lake-S configuration with DDR5-8000 memory. That data put it about 16% ahead of the Core Ultra 9 285K in games at a 285 W power limit, rising to around 33% at 296 W. Different power limits and memory speeds mean none of these numbers line up neatly, and every one of them still needs independent testing.
What Intel has actually said
Officially, Intel has confirmed only the broad strokes. On its October 29 earnings call it said Nova Lake is its first client product on the 18A-P process, that it is tracking ahead of schedule, and that more details will come at CES in January. Nothing on clocks, core counts, pricing or gaming performance has been published by Intel itself.
Why it matters
Arrow Lake left Intel behind AMD's X3D chips in gaming, and a 20% jump would put Nova Lake back in the conversation for high-refresh esports rigs. Until reviewers run real games on retail chips, treat the leak as a target rather than a result. SEA builders weighing an upgrade now have no Intel pricing or regional dates to plan around.
CES 2027 runs January 6 to 9 in Las Vegas, where Intel is expected to put its own figures on the table.
