AMD Radeon 860M vs NVIDIA H100 CNX Comparison

Head-to-Head Benchmarks

The recorded data shows that the AMD Radeon 860M has two benchmark entries, while the NVIDIA H100 CNX has none. The Radeon 860M scores 22,759 in Geekbench OpenCL and 30,043 in Geekbench Vulkan, producing an average benchmark score of 26,401. The H100 CNX, by contrast, has no recorded benchmark scores, so direct head-to-head comparisons cannot be made from the database. This absence of data for the H100 CNX places it at the 50th percentile among all GPUs, while the Radeon 860M sits at the 72nd percentile. In terms of raw average score, the Radeon 860M delivers 26,401 points, whereas the H100 CNX records zero, indicating that the database currently holds no performance measurements for the NVIDIA part.

The Radeon 860M's nearest rivals in the database include the NVIDIA GeForce MX550 with an average score of 26,421, a delta of -0.1% relative to the 860M, meaning the MX550 is essentially tied. The NVIDIA GeForce RTX 5060 scores 26,331, a delta of +0.3%, so the 860M trails by a third of a percent. The AMD Radeon RX 5700 XT 50th Anniversary scores 26,553, a delta of -0.6%, and the NVIDIA RTX A4000 scores 26,683, a delta of -1.1%. These deltas confirm that the Radeon 860M performs within a narrow band around these discrete and workstation GPUs, despite being an integrated processor. The H100 CNX has no nearest rivals listed, reinforcing that no comparative benchmark data exists for it.

Because the head-to-head benchmark array is empty, the database shows zero wins for both products. The practical takeaway is that the Radeon 860M has measurable performance data, while the H100 CNX does not. Any assessment of the H100 CNX must rely on its architectural specifications rather than benchmark outcomes.

Architecture Differences

The AMD Radeon 860M uses the Krackan Point chip built on RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile. Its transistor count and die size are listed as unknown, and transistor density is not provided. The NVIDIA H100 CNX uses the GH100 chip built on Hopper architecture, fabricated on a 5 nm process at TSMC. It has 80,000 million transistors on a 814 mm² die, giving a transistor density of 98.3 million per square millimeter. The H100 CNX belongs to the Server Hopper generation.

Clock behavior differs substantially. The Radeon 860M runs at a base clock of 600 MHz and a boost clock of 3000 MHz, while the H100 CNX runs at a base clock of 690 MHz and a boost clock of 1845 MHz. Memory architecture is fundamentally different: the Radeon 860M uses system shared memory with a system-dependent bandwidth, while the H100 CNX has 80 GB of HBM2e memory on a 5120-bit bus, delivering 2.04 TB/s of bandwidth. The H100 CNX memory clock is 1593 MHz, translating to 3.2 Gbps effective.

Compute resources diverge sharply. The Radeon 860M has 512 shading units, 32 texture mapping units, and 16 raster operation pipelines. It includes 8 ray tracing cores but no tensor cores. The H100 CNX has 14,592 shading units, 456 texture mapping units, and 24 raster operation pipelines. It includes 456 tensor cores but no dedicated ray tracing cores. Pixel rates are close: 48.00 GPixel/s for the Radeon 860M versus 44.28 GPixel/s for the H100 CNX. Texture rates differ greatly: 96.00 GTexel/s for the Radeon 860M versus 841.3 GTexel/s for the H100 CNX. Floating-point throughput shows a massive gap: FP32 is 3.072 TFLOPS for the Radeon 860M versus 53.84 TFLOPS for the H100 CNX. FP16 on the Radeon 860M is 3.072 TFLOPS with a 1:1 ratio, while the H100 CNX reaches 215.4 TFLOPS with a 4:1 ratio.

Power and physical characteristics differ as well. The Radeon 860M has a TDP of 15 W, is an IGP with no power connectors, and uses a PCIe 4.0 x8 interface. The H100 CNX has a TDP of 350 W, is a dual-slot card with an 8-pin EPS power connector, a suggested PSU of 750 W, and uses PCIe 5.0 x16. The H100 CNX measures 267 mm in length and 111 mm in height, with no width given. The Radeon 860M has no dimensions listed. Display outputs are portable-device dependent for the Radeon 860M, while the H100 CNX has no outputs. API support also diverges: the Radeon 860M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H100 CNX lists no DirectX, OpenGL, or Vulkan support in the database.

Where Each One Wins

The Radeon 860M wins in any scenario requiring a low-power integrated solution. Its 15 W TDP and IGP form factor make it suitable for portable devices, and its display outputs are portable-device dependent, confirming a mobile-oriented design. Its boost clock of 3000 MHz is the highest clock speed recorded between the two parts, offering a frequency advantage. The presence of ray tracing cores gives it a feature that the H100 CNX lacks entirely. In benchmark terms, the Radeon 860M has actual scores, with the Vulkan result of 30,043 being its strongest recorded metric.

The H100 CNX wins in raw compute throughput and memory capacity. Its FP32 output of 53.84 TFLOPS is roughly 17.5 times higher than the Radeon 860M's 3.072 TFLOPS, based on the recorded numbers. Its FP16 output of 215.4 TFLOPS is 70 times higher. The 80 GB of HBM2e memory with 2.04 TB/s bandwidth dwarfs the system-shared memory of the Radeon 860M. The 456 tensor cores give it a dedicated acceleration path for tensor workloads, which the Radeon 860M does not have. Texture rate of 841.3 GTexel/s is roughly 8.8 times higher than the Radeon 860M's 96.00 GTexel/s. The H100 CNX also has a much larger shading unit count, 14,592 versus 512, and a wider memory bus at 5120 bits versus system shared.

The H100 CNX wins on process scale in terms of transistor count, with 80,000 million transistors versus an unknown count for the Radeon 860M. The H100 CNX also has a larger die at 814 mm². However, the Radeon 860M uses a more advanced 4 nm process compared to the H100 CNX's 5 nm process, which partially explains the Radeon's lower power draw. The Radeon 860M also wins on API support, offering DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the H100 CNX has none listed.

The Verdict

The data indicates two entirely different product categories. The AMD Radeon 860M is an integrated GPU for mobile devices, confirmed by its IGP slot width, 15 W TDP, PCIe 4.0 x8 interface, and portable-device-dependent display outputs. The NVIDIA H100 CNX is a server-oriented accelerator, confirmed by its Server Hopper generation, dual-slot form factor, 350 W TDP, 8-pin EPS power connector, and lack of display outputs. Users needing a GPU for a laptop or portable device should consider the Radeon 860M, as it has recorded benchmark scores and a 72nd percentile ranking. Users needing a high-throughput server accelerator with tensor cores and massive memory bandwidth should consider the H100 CNX, based on its specifications.

The Radeon 860M's average benchmark score of 26,401 places it near the GeForce MX550, RTX 5060, RX 5700 XT 50th Anniversary, and RTX A4000, all within roughly one percent of each other. The H100 CNX has no benchmark data, so its performance ranking is undetermined beyond its 50th percentile placement. The H100 CNX's successor is listed as Server Blackwell, and its predecessor is Server Ada, indicating a clear product lineage. The Radeon 860M's predecessor is Navi II IGP, with no successor listed.

In terms of production status, both are Active. The Radeon 860M was released on 2025-02-28, while the H100 CNX was released on 2023-03-20. Neither has a launch MSRP in the database. The choice between them is dictated by workload: the Radeon 860M is designed for integrated mobile graphics, while the H100 CNX is designed for server compute with tensor acceleration.
