Faster to the optimum than quantum
VERTEX is the world's first wafer-scale solver for the Maximum Cut problem, delivering a 45–165× speedup over quantum solvers and digital annealers on large-scale sparse graphs.
VERTEX is the world's fastest Maximum Cut solver for large sparse graphs.
On G11, VERTEX reaches the same cut 164.9× faster than the Fujitsu Digital Annealer.
Across G11–G13, VERTEX beats D-Wave Hybrid's cut and hits the target roughly 45× faster.
On G14, VERTEX matches the Toshiba Simulated Bifurcation Machine 19.7× faster.
Built Wafer-Scale
VERTEX runs on the Cerebras WSE-3, the largest chip ever built, with 900,000 cores and 44 GB of on-chip SRAM on a single silicon wafer. Every core is wired to its neighbors over an on-chip fabric. The entire sparse graph stays resident on-chip, so every spin updates in lockstep with no off-chip memory traffic.
900,000 independent cores per wafer.
Gset 81: Unsolved for 25 years, solved by VERTEX today. Gset is the canonical Max-Cut benchmark. It contains sparse, frustrated, spin glass systems. Some, like G81, have been unsolved for decades. VERTEX solves them in record time.
Toroidal lattice
An 800-spin toroidal grid. VERTEX reaches the certified optimum, a cut of 564.
Planar graph
An 800-node planar Max-Cut instance. VERTEX reaches the certified optimum, a cut of 3,064.
Largest 2D spin glass
20,000 spins, 40,000 couplings — a 25-year-open benchmark, certified optimal at 14,060.
Best-known solutions, reached in record time
Best-known cuts from the Gset suite. D-Wave Hybrid and Toshiba SBM from Vodeb et al. (2024); Fujitsu DA3 from Shaglel et al. (2025). Δcut = cut(VERTEX) − cut(reference); Fₜ = reference time ÷ VERTEX time to an equal-or-higher cut. VERTEX reaches the best-known cut on all four instances.
Fixed-budget quality, 10-second cut
Results from Yang et al. (2025): best cut each solver reaches within a 10-second budget. Δcut is measured against the VERTEX operating point named in each panel.
Quality-at-budget data from Yang et al. (2025), Table 1; cuts reported as absolute values. A positive Δcut means VERTEX reaches a higher cut. VERTEX matches the best reported G11 cut and exceeds every reported G14 cut.
