NVIDIA Rubin Ultra GPU: specs and benchmarks
Contents
Summary
NVIDIA started Rubin Ultra GPU sales on 2027. This is a Rubin Ultra architecture desktop card based on 3 nm manufacturing process and primarily aimed at designers. 1024 GB of HBM4e memory clocked at 1.9 GHz are supplied, and together with 32768 Bit memory interface this creates a bandwidth of 31.1 TB/s.
Compatibility-wise, this is a sxm module graphics card attached via PCIe 6.0 x16 interface. No additional power connector is required, and power consumption is at 3600 Watt.
