The NVIDIA H800 80GB is a specialized AI accelerator built on the Hopper architecture, specifically engineered to comply with U.S. export controls for restricted markets such as China Philisun Getdeploying. It serves as a modified version of the flagship H100, maintaining high AI compute performance while intentionally throttling communication speeds Philisun.

1. Key Product Specifications

The H800 retains the core AI processing power of the H100 but features significant limitations in interconnect and high-precision scientific computing Getdeploying Techpowerup:

* AI Performance: Delivers up to 1,513 TFLOPS (FP16/BF16) and 3,026 TFLOPS (FP8) with sparsity, making it a powerful engine for Large Language Model (LLM) training and inference Philisun.

* Memory: Features 80GB of HBM2e (PCIe) or HBM3 (SXM) memory with a bandwidth of 2.0 TB/s Getdeploying Techpowerup.

* NVLink Bandwidth: Capped at 400 GB/s bidirectional, which is roughly 44% of the H100's speed. This restricts its efficiency in massive "super-clusters" of thousands of GPUs Philisun Getdeploying.

* Scientific Computing: High-precision (FP64) performance is gutted to ~1 TFLOPS (vs. 34 TFLOPS on H100) to prevent its use in military-grade scientific modeling Philisun.

2. Market Trends & Pricing (2026)

The market for H800 is driven by geopolitical restrictions, making it a highly sought-after "legal" high-end option in restricted regions Getdeploying.

* Retail Pricing: Due to limited supply and high demand in secondary markets, individual units can command between $25,000 and $40,000 Intuitionlabs Hashrateindex.

* Cloud Trends: While H100s are widely available on Western clouds for ~$3.34/hr, H800s are more common in specialized regional clouds, with pricing often slightly lower due to the reduced interconnect performance Getdeploying Getdeploying.

* Stability: Used H100 prices have stabilized around $18,000–$22,000, while the H800 remains volatile as newer models like the B200 and H200 shift enterprise focus elsewhere Gpunex Intuitionlabs.

3. Sourcing Insights

B2B sourcing for the H800 80GB remains active, with suppliers primarily located in tech hubs like Shenzhen and Guangzhou.

* Available Stock: Listings range from brand new SXM5 modules to passive PCIe cards for data centers.

* Pricing Variations: Market prices on B2B platforms range from $15,000 to over $36,000 depending on the specific SKU (PCIe vs. SXM) and order quantity.
