Blackwell Halo leak
Leaks suggest NVIDIA is testing a 'Blackwell Halo' SKU positioned above the RTX‑5090 — potentially the most powerful gaming/creator GPU in the stack if real. (igorslab.de) The rumor matters because NVIDIA is simultaneously pushing rack‑level CPUs and storage at GTC, so a new halo GPU would keep its consumer and creative ecosystems humming. (digitimes.com)
Leaked engineering tallies circulating in the rumor chain put enabled shader counts “just under 23,000” for the alleged halo prototype versus 21,760 in existing flagship silicon. (igorslab.de) NVIDIA’s GB202 full-die specification documents a 192‑SM design equating to roughly 24,576 CUDA cores and a 512‑bit memory interface, while the shipping GeForce variant is documented at 170 SMs with 21,760 CUDA cores, 32 GB GDDR7, 96 MB L2 cache and a 575 W TGP. (guru3d.com) NVIDIA already sells GB202-based workstation hardware — the RTX PRO 6000 Blackwell ships with up to 96 GB of GDDR7 — demonstrating the company can enable more of the GB202 die in non-GeForce SKUs. (nvidia.com) Industry trackers and hardware sites that picked up the leak link potential halo work to a Q3 2026 development window and variously label the concept as an RTX 5090 Ti or a TITAN-class card rather than a standard Super refresh. (videocardz.com) Sources covering previous NVIDIA cycles warn that late-stage halo prototypes have circulated publicly before without reaching retail — the same outlets note prior TITAN/“Ti” prototypes that were ultimately shelved. (videocardz.com) NVIDIA’s GTC 2026 pivot to rack-scale infrastructure — including a Vera CPU rack that packs 256 Vera CPUs and the Groq 3 LPX inference racks slated for second‑half 2026 — shifts company engineering and supply priorities in ways analysts say could affect the timing or scope of any new consumer halo GPU.
