AMD Radeon RX 6850M XT vs NVIDIA H200 NVL Comparison

Where Each One Wins

The benchmark data presents a starkly one-sided comparison. The NVIDIA H200 NVL wins the single shared benchmark test, Geekbench OpenCL, with a score of 334,891 against the AMD Radeon RX 6850M XT's 85,040. This represents a 293.8% advantage for the NVIDIA part. The H200 NVL is positioned in the 100th percentile of all GPUs in the database, while the RX 6850M XT sits at the 92nd percentile.

However, the two products occupy entirely different performance domains. The AMD Radeon RX 6850M XT has its own benchmark portfolio that the H200 NVL cannot participate in, as the NVIDIA part has no display outputs and no graphics API support. The RX 6850M XT records scores in 3DMark Steel Nomad DX12 (2,257), Geekbench Metal (128,981), and Geekbench Vulkan (99,483). These tests measure rasterization and real-time graphics workloads, areas where the AMD mobile part is designed to compete.

The H200 NVL's single recorded benchmark reflects its compute-oriented design. Its nearest rivals in the database, based on average benchmark scores, are the NVIDIA B300 SXM6 AC (369,831), NVIDIA B200 (345,482), AMD Instinct MI300X (317,994), and NVIDIA L40S (295,763). The H200 NVL trails the B300 SXM6 AC by 9.4% and the B200 by 3.1%, while leading the MI300X by 5.3% and the L40S by 13.2%. These deltas position it as a mid-tier entry within a family of data-center accelerators.

The RX 6850M XT, by contrast, sits among older and consumer-oriented parts. Its nearest rivals include the NVIDIA GeForce RTX 5090 (79,842), Tesla P100 PCIe 16 GB (79,605), Tesla P100 PCIe 12 GB (79,396), and RTX 5090 D (77,712). The deltas here are small, ranging from -1.1% to 1.6%, indicating a tightly clustered performance band around the AMD part's average score of 78,940.

Architecture Differences

The architectural gap between these two products is fundamental. The H200 NVL uses the GH100 chip built on Hopper architecture, fabricated on a 5 nm process at TSMC. It contains 80,000 million transistors on a die measuring 814 mm², yielding a transistor density of 98.3 million per square millimeter. The RX 6850M XT uses the Navi 22 chip on RDNA 2.0 architecture, fabricated on a 7 nm process, also at TSMC. It contains 17,200 million transistors on a 335 mm² die, with a density of 51.3 million per square millimeter.

The H200 NVL is a server accelerator with no display outputs and no DirectX, OpenGL, or Vulkan support. Its API fields are all marked N/A. The RX 6850M XT is a mobile graphics processor with portable-device-dependent display outputs and full API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Memory architecture differs completely. The H200 NVL packs 141 GB of HBM3e on a 6144-bit bus, delivering 4.89 TB/s of bandwidth. The RX 6850M XT has 12 GB of GDDR6 on a 192-bit bus, providing 432.0 GB/s. The NVIDIA part's memory clock is listed at 1593 MHz with 6.4 Gbps effective transfer, while the AMD part runs at 2250 MHz with 18 Gbps effective.

Compute resources are heavily skewed. The H200 NVL has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The RX 6850M XT has 2,560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. The NVIDIA part has no dedicated RT cores listed; the AMD part has no tensor cores listed.

Clock speeds favor the AMD part in raw frequency. The RX 6850M XT has a base clock of 2321 MHz and a boost of 2581 MHz, with a game clock of 2463 MHz. The H200 NVL runs at 1365 MHz base and 1785 MHz boost. Despite lower clocks, the H200 NVL achieves far higher throughput: 60.32 TFLOPS FP32 and 120.6 TFLOPS FP16 (2:1), versus 13.21 TFLOPS FP32 and 26.43 TFLOPS FP16 for the AMD part.

Specification Differences

The two GPUs differ across nearly every measurable specification. Power consumption is a major divider: the H200 NVL has a TDP of 600 W with dual-slot cooling and an 8-pin EPS connector, requiring a 1000 W suggested PSU. The RX 6850M XT has a TDP of 165 W, is an IGP (integrated graphics processor) form factor, and uses no power connectors.

The H200 NVL measures 267 mm in length and 111 mm in height, while the RX 6850M XT has no listed physical dimensions. The NVIDIA part uses PCIe 5.0 x16; the AMD part uses PCIe 4.0 x16. The H200 NVL has no display outputs; the RX 6850M XT's outputs are portable-device dependent.

The NVIDIA part has 16,896 shading units, 528 TMUs, and 24 ROPs, with 528 tensor cores and no RT cores. The AMD part has 2,560 shading units, 160 TMUs, and 64 ROPs, with 40 RT cores and no tensor cores. The H200 NVL's pixel rate is 42.84 GPixel/s and texture rate is 942.5 GTexel/s. The RX 6850M XT's pixel rate is 165.2 GPixel/s and texture rate is 413.0 GTexel/s.

Release timing also differs. The H200 NVL was released on November 17, 2024, as part of the Server Hopper (Hxx) generation, with its predecessor being Server Ada and successor being Server Blackwell. The RX 6850M XT was released on January 3, 2022, within the Navi Mobile (RX 6000M) generation, with its predecessor being Polaris Mobile and no successor listed.

Head-to-Head Benchmarks

The database records only one head-to-head benchmark between these two products: Geekbench OpenCL. The NVIDIA H200 NVL scores 334,891, while the AMD Radeon RX 6850M XT scores 85,040. The delta is 293.8% in favor of the NVIDIA part.

This score disparity aligns with the compute-focused positioning of the H200 NVL. Its OpenCL result is more than four times higher than the RX 6850M XT's, reflecting the massive difference in shading units (16,896 versus 2,560), memory bandwidth (4.89 TB/s versus 432.0 GB/s), and FP32 throughput (60.32 versus 13.21 TFLOPS).

The RX 6850M XT's own benchmark suite shows strengths in graphics workloads. Its 3DMark Steel Nomad DX12 score of 2,257, Geekbench Metal score of 128,981, and Geekbench Vulkan score of 99,483 all indicate functional real-time rendering capability. The H200 NVL has no comparable scores because it lacks graphics APIs entirely.

Contextualizing the H200 NVL's OpenCL win against its rivals shows it is not the top performer in its class. The B300 SXM6 AC leads it by 9.4%, and the B200 leads by 3.1%. The MI300X trails by 5.3%, and the L40S trails by 13.2%. For the RX 6850M XT, its nearest rival deltas are all within 1.6%, with the RTX 5090 D trailing by 1.6% and the RTX 5090 leading by 1.1%.

The Verdict

The NVIDIA H200 NVL is the clear winner in raw compute performance. Its 293.8% lead in Geekbench OpenCL over the RX 6850M XT is decisive. The 141 GB of HBM3e memory, 4.89 TB/s bandwidth, and 60.32 TFLOPS FP32 throughput make it a data-center accelerator for large-scale compute workloads. It ranks in the 100th percentile of all GPUs, above the 92nd percentile of the AMD part.

The AMD Radeon RX 6850M XT serves a different purpose entirely. It is a mobile graphics processor with full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, plus 40 ray tracing cores. Its 165 W TDP and IGP form factor suit portable devices. Its benchmark scores in 3DMark Steel Nomad, Metal, and Vulkan demonstrate graphics capability that the H200 NVL cannot offer, since the NVIDIA part has no display outputs or graphics APIs.

For users selecting a GPU strictly for compute density, the H200 NVL is the superior choice. For users needing a mobile GPU with real-time graphics and ray tracing, the RX 6850M XT is the only viable option between the two. The data shows no overlap in their intended roles. The H200 NVL's nearest rivals are other server accelerators like the B200 and MI300X, while the RX 6850M XT's closest competitors are consumer and older professional GPUs like the RTX 5090 and Tesla P100.

The production status reinforces this split. The H200 NVL remains active, while the RX 6850M XT is end-of-life. Any new deployment requiring the AMD part would rely on existing inventory. The NVIDIA part continues in active production, aligning with its server-market longevity. The choice is not about which GPU is better overall; it is about which workload domain the buyer operates in.
