However, the H200 NVL achieves a 100th percentile ranking among all GPUs, while the RTX 6000D sits at the 98th percentile, indicating that both are elite performers in their respective classes.

FAQ

Q: Which GPU has higher raw compute throughput in FP32 operations?

A: The NVIDIA RTX 6000D delivers 97.04 TFLOPS of FP32 performance, which is substantially higher than the H200 NVL's 60.32 TFLOPS. This represents a 60.9% advantage for the RTX 6000D in single-precision floating-point workloads.

Q: How does memory bandwidth compare between the two cards?

A: The H200 NVL offers 4.89 TB/s of memory bandwidth using HBM3e across a 6144-bit bus, while the RTX 6000D provides 1.40 TB/s via GDDR7 on a 448-bit bus. The H200 NVL delivers 3.5 times the memory bandwidth of the RTX 6000D.

Q: What is the difference in memory capacity?

A: The H200 NVL features 141 GB of HBM3e memory, while the RTX 6000D is equipped with 84 GB of GDDR7 memory. The H200 NVL offers 57 GB more memory capacity, which is critical for large model inference and datasets that exceed the RTX 6000D's capabilities.

Q: Which GPU supports real-time ray tracing?

A: Only the RTX 6000D includes dedicated ray tracing cores, featuring 156 RT cores. The H200 NVL has no RT core count listed, and its API support is marked as N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for graphics rendering workloads.

Q: How do the two GPUs compare in benchmark scores relative to their closest rivals?

A: The H200 NVL scores 5.3% higher than the AMD Instinct MI300X (317,994) and 13.2% higher than the NVIDIA L40S (295,763), but trails the NVIDIA B200 by 3.1% (345,482). The RTX 6000D is 4.7% ahead of the A100 SXM4 40 GB (187,147) and 6.1% ahead of the RTX 5000 Ada Generation (184,664), while sitting 5.4% behind the A100 PCIe 80 GB (207,124).

Q: What is the form factor difference between these cards?

A: Both are dual-slot cards, but the H200 NVL measures 267 mm in length and 111 mm in height, while the RTX 6000D is longer at 304 mm and taller at 137 mm, with a width of 40 mm. The H200 NVL has no display outputs, whereas the RTX 6000D includes 4x DisplayPort 2.1b connectors.

Architecture Differences

The H200 NVL is built on the Hopper architecture (chip GH100) and belongs to the Server Hopper (Hxx) generation, while the RTX 6000D uses the Blackwell 2.0 architecture (chip GB202) from the Blackwell PRO W (x000) generation. Both GPUs are fabricated by TSMC on a 5 nm process node, but the transistor counts differ significantly: the H200 NVL packs 80,000 million transistors on an 814 mm² die, whereas the RTX 6000D contains 92,200 million transistors on a smaller 750 mm² die. This results in a transistor density of 98.3M per mm² for the H200 NVL versus 122.9M per mm² for the RTX 6000D, indicating the Blackwell chip achieves higher packing efficiency.

Clock speeds reveal another architectural divergence. The H200 NVL operates at a 1365 MHz base clock with a 1785 MHz boost, while the RTX 6000D runs significantly faster at 1992 MHz base and 2430 MHz boost. The memory subsystems are fundamentally different: the H200 NVL uses HBM3e with a 6144-bit interface and 1593 MHz memory clock (6.4 Gbps effective), whereas the RTX 6000D employs GDDR7 with a 448-bit bus and 1560 MHz memory clock (25 Gbps effective). These memory architectures explain the H200 NVL's massive 4.89 TB/s bandwidth advantage despite the RTX 6000D's higher effective memory clock speed.

Compute unit configurations also differ notably. The H200 NVL has 16,896 shading units, 528 TMUs, and only 24 ROPs, while the RTX 6000D features 19,968 shading units, 624 TMUs, and 192 ROPs. The RTX 6000D additionally includes 156 RT cores and 624 tensor cores, while the H200 NVL lists 528 tensor cores with no RT core count specified. The FP16 performance profiles are particularly telling: the H200 NVL delivers 120.6 TFLOPS (2:1 ratio), while the RTX 6000D achieves 97.04 TFLOPS (1:1 ratio), reflecting different precision handling strategies.

Head-to-Head Benchmarks

The only direct benchmark comparison available is the Geekbench OpenCL test, where the RTX 6000D scores 388,405 against the H200 NVL's 334,891. This gives the RTX 6000D a 13.8% advantage in this workload, a meaningful margin that reflects its higher clock speeds and greater shading unit count. The RTX 6000D's 19,968 shading units running at up to 2430 MHz boost clearly outperform the H200 NVL's 16,896 shading units at a maximum 1785 MHz boost in this OpenCL compute scenario.

However, context from the nearest rivals suggests the H200 NVL's position is competitive within the broader server GPU landscape. The H200 NVL's score of 334,891 places it 3.1% behind the NVIDIA B200 (345,482) but 5.3% ahead of the AMD Instinct MI300X (317,994) and 13.2% beyond the NVIDIA L40S (295,763). This indicates the H200 NVL is a strong mid-tier performer among data center accelerators, even if it loses to the RTX 6000D in this specific benchmark.

The RTX 6000D's average benchmark score of 195,964 is pulled down by the inclusion of the 3DMark Steel Nomad DX12 test (3,522), which the H200 NVL cannot run due to its lack of graphics API support. When considering only the Geekbench OpenCL result, the RTX 6000D demonstrates clear superiority in general-purpose compute. The RTX 6000D also holds a 0.8% edge over the Tesla V100S PCIe 32 GB (194,415) and a 4.7% lead over the A100 SXM4 40 GB (187,147), but trails the A100 PCIe 80 GB by 5.4% (207,124) in average score.

Where Each One Wins

The H200 NVL is the clear winner for memory-bound workloads. Its 141 GB of HBM3e memory and 4.89 TB/s bandwidth provide 68% more capacity and 3.5 times the bandwidth of the RTX 6000D, making it the superior choice for large language model inference, massive dataset processing, and applications where model weights exceed the RTX 6000D's 84 GB limit. The H200 NVL's 120.6 TFLOPS FP16 performance (2:1 ratio) also gives it a 24.2% advantage in mixed-precision AI workloads, and its 100th percentile ranking among all GPUs reflects its position as a top-tier server accelerator. Its smaller footprint (267 mm length vs 304 mm) and simpler 8-pin EPS power connector may facilitate integration into existing server infrastructure.

The RTX 6000D dominates in graphics and workstation applications. Its 156 RT cores, 4x DisplayPort 2.1b outputs, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API support make it the only viable option for real-time rendering, 3D visualization, and CAD workloads. The RTX 6000D's 97.04 TFLOPS FP32 performance is 60.9% higher than the H200 NVL's, and its 466.6 GPixel/s pixel rate and 1,516.3 GTexel/s texture rate are substantial improvements (10.9x and 1.6x respectively) over the H200 NVL's 42.84 GPixel/s and 942.5 GTexel/s. The RTX 6000D also wins the head-to-head OpenCL benchmark by 13.8%, and its higher clock speeds (1992 MHz base, 2430 MHz boost) provide better responsiveness for interactive workloads.

For data center operators focused purely on AI inference, the H200 NVL's memory advantage is decisive. For workstation users needing graphics, ray tracing, and compute versatility, the RTX 6000D is the only option with display capabilities and graphics API support. The RTX 6000D's 98th percentile ranking still places it among the elite GPUs, but its average benchmark score of 195,964 reflects the inclusion of graphics tests that the H200 NVL cannot participate in, underscoring the fundamental difference in their intended use cases.
