RTX PRO 5000 Blackwell adds a 72GB VRAM option: 14,080 CUDA cores, GDDR7 ECC, 300 W, PCIe 5.0. Specs, memory-bus ambiguity, pro workloads, and pricing context.
NVIDIA has officially confirmed the availability of the professional RTX PRO 5000 Blackwell with 72 GB of VRAM, a 50% jump over the previously announced 48 GB version. The announcement came via the company blog after both configurations appeared on the product page, effectively confirming plans to bring the higher-memory model to market.
The RTX PRO 5000 72GB does not change the graphics processor and is essentially a capacity bump. Both variants are built on the Blackwell architecture with 14,080 CUDA cores, fifth‑generation Tensor Cores, and fourth‑generation RT Cores, while keeping power draw at 300 W. The card uses GDDR7 with ECC, connects over PCIe 5.0 x16, and carries the same display outputs, including four DisplayPort 2.1b. A practical, no‑surprises spec sheet that keeps power budgets predictable.
One detail stands out around memory configuration. NVIDIA’s official materials still list a 512‑bit interface and 1,344 GB/s of bandwidth, yet those figures align more naturally with a 384‑bit bus at 28 Gbps. If a 512‑bit bus were in play, the same bandwidth would imply a lower memory speed, which introduces ambiguity and leaves room for clarification from the company. It’s the kind of discrepancy that tends to draw extra scrutiny from spec‑watchers.
The card targets professional workloads—from visualization to AI and demanding compute. NVIDIA cites performance of up to 65 TFLOPS in FP32 and up to 196 TFLOPS using RT Cores, along with 2,064 AI TOPS. Modern graphics and compute APIs are supported, including DirectX 12, Vulkan, and CUDA 12.8. Cooling comes via a full‑height, active dual‑slot design. The configuration reads as a deliberate play for heavy scenes and larger models that routinely spill past smaller memory pools.
Sales of the RTX PRO 5000 72GB will go through NVIDIA partners. Pricing has not yet been disclosed. For context, the 48 GB version sells for roughly $4,250 to $4,600, while higher‑tier RTX PRO 6000 models sit above $8,300. Where the 72 GB card lands could meaningfully influence purchasing decisions for teams constrained by memory ceilings.
