AMD Radeon 840M vs NVIDIA H200 NVL Comparison

Head-to-Head Benchmarks

The recorded benchmark data shows a decisive performance gap between these two accelerators, though the comparison is limited by the available measurements. The AMD Radeon 840M has no recorded benchmark scores in the database, while the NVIDIA H200 NVL has a single Geekbench OpenCL score of 334,891. This places the H200 NVL at the 100th percentile of all GPUs in the database, while the Radeon 840M sits at the 50th percentile with an average benchmark score of zero.

The H200 NVL's score of 334,891 places it among the top-tier server accelerators. Relative to its nearest rivals, the H200 NVL trails the NVIDIA B200 by 3.1% (the B200 scores 345,482) but surpasses the AMD Instinct MI300X by 5.3% (which scores 317,994). The H200 NVL also leads the NVIDIA B300 SXM6 AC by 9.4% (that part scores 369,831) and outperforms the NVIDIA L40S by 13.2% (which scores 295,763). These deltas confirm that the H200 NVL delivers competitive compute performance within the high-end server segment, though it is not the absolute fastest in this peer group.

For the Radeon 840M, the absence of benchmark scores means no direct head-to-head percentage comparison is possible. The database records zero wins for the Radeon 840M and zero wins for the H200 NVL in head-to-head benchmark matchups, reflecting the lack of overlapping test data rather than any performance equivalence. The Radeon 840M's 50th percentile ranking, based on no measured scores, should be interpreted as a placeholder position rather than an empirical result.

Architecture Differences

The two parts come from entirely different design philosophies and market segments. The AMD Radeon 840M uses the Krackan Point chip built on RDNA 3.5 architecture, classified as part of the Navi III IGP (Strix Point Mobile) generation. It is fabricated on a 4 nm process at TSMC. The NVIDIA H200 NVL uses the GH100 chip based on Hopper architecture, belonging to the Server Hopper (Hxx) generation, and is built on a 5 nm process, also at TSMC.

The transistor and die data illustrate the scale difference. The H200 NVL contains 80,000 million transistors on a die size of 814 mm², yielding a transistor density of 98.3M per mm². The Radeon 840M's transistor count and die size are listed as unknown in the database. Clock behavior also diverges sharply: the Radeon 840M runs at a base clock of 400 MHz and boosts to 2900 MHz, while the H200 NVL operates at a base of 1365 MHz and boosts to 1785 MHz, with memory clocked at 1593 MHz (6.4 Gbps effective).

Compute resources differ by orders of magnitude. The Radeon 840M features 256 shading units, 16 texture mapping units, 8 ROPs, and 4 ray tracing cores. The H200 NVL packs 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The Radeon 840M has no tensor cores listed. Pixel and texture rates reflect these differences: the Radeon 840M produces 23.20 GPixel/s and 46.40 GTexel/s, while the H200 NVL reaches 42.84 GPixel/s and 942.5 GTexel/s. Floating-point throughput shows the largest gap: the Radeon 840M delivers 1,484.8 GFLOPS for both FP32 and FP16 (at a 1:1 ratio), whereas the H200 NVL achieves 60.32 TFLOPS for FP32 and 120.6 TFLOPS for FP16 (at a 2:1 ratio).

Memory architecture is fundamentally different. The Radeon 840M uses system-shared memory with a system-dependent bandwidth and a system-shared bus width. The H200 NVL uses 141 GB of HBM3e memory on a 6144-bit bus, providing 4.89 TB/s of bandwidth. The H200 NVL is a dual-slot card with an 8-pin EPS power connector and a suggested PSU of 1000 W, consuming 600 W TDP. The Radeon 840M is an integrated graphics processor (IGP) with a 15 W TDP, no power connectors, and a PCIe 4.0 x8 interface. The H200 NVL uses PCIe 5.0 x16.

API support also differs. The Radeon 840M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H200 NVL lists N/A for DirectX, OpenGL, and Vulkan, reflecting its server-oriented focus. The H200 NVL has no display outputs, while the Radeon 840M's display outputs are portable-device dependent. The H200 NVL measures 267 mm in length and 111 mm in height; the Radeon 840M has no recorded dimensions.

The Verdict

The data presents a clear distinction in purpose and capability. The NVIDIA H200 NVL is a server-class accelerator with measured performance at the 100th percentile, a 334,891 OpenCL score, and substantial compute resources. The AMD Radeon 840M is an integrated mobile GPU with no recorded benchmarks, a 15 W power envelope, and modest specifications. Any workload requiring dense FP32 or FP16 throughput, large memory capacity, or high-bandwidth access would rely on the H200 NVL. The Radeon 840M serves scenarios where low power consumption, integrated graphics, and portability are priorities, but the database shows no empirical performance evidence for it.

Users seeking a part for graphics rendering, gaming, or client-side compute would find the Radeon 840M's feature set relevant, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Users needing massive parallel compute for AI, scientific simulation, or data center workloads would select the H200 NVL, which trades display outputs and consumer APIs for raw throughput and a 141 GB memory pool. The H200 NVL's 5.3% lead over the AMD Instinct MI300X and its 13.2% advantage over the NVIDIA L40S position it as a strong, though not dominant, performer in its peer group.

Where Each One Wins

The AMD Radeon 840M wins in power efficiency and portability. Its 15 W TDP, integrated form factor, and lack of power connectors make it suitable for thin-and-light mobile devices. The higher boost clock of 2900 MHz and support for consumer graphics APIs (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4) indicate a design aimed at everyday graphics and light compute tasks. The 4 ray tracing cores provide hardware acceleration for ray-traced effects in supported applications.

The NVIDIA H200 NVL wins in every measured performance category. Its 334,891 OpenCL score, 60.32 TFLOPS FP32 output, and 120.6 TFLOPS FP16 output place it in a different performance class entirely. The 141 GB HBM3e memory with 4.89 TB/s bandwidth enables large model inference and training workloads that the system-shared memory of the Radeon 840M cannot approach. The 528 tensor cores provide dedicated matrix math acceleration, a feature absent from the Radeon 840M. The H200 NVL also leads in texture rate (942.5 GTexel/s versus 46.40 GTexel/s) and pixel rate (42.84 GPixel/s versus 23.20 GPixel/s), although these metrics matter less for a server part without display outputs.

The benchmark percentile data reinforces the split: the H200 NVL sits at the 100th percentile of all GPUs, while the Radeon 840M has no measured score to substantiate its 50th percentile ranking. The H200 NVL's nearest rivals confirm its competitive position: it is 3.1% slower than the NVIDIA B200, 5.3% faster than the AMD Instinct MI300X, 9.4% faster than the NVIDIA B300 SXM6 AC, and 13.2% faster than the NVIDIA L40S. These deltas establish the H200 NVL as a top-tier compute accelerator, whereas the Radeon 840M remains an unverified entry in the database.
