AMD Radeon 820M vs NVIDIA H200 NVL Comparison

AMD Radeon 820M and NVIDIA H200 NVL occupy completely different segments of the GPU market, and the recorded data confirms this divide. The Radeon 820M is a 15 W integrated processor from AMD's Krackan Point 2 chip, built on TSMC's 4 nm process, while the H200 NVL is a 600 W dual-slot server accelerator based on NVIDIA's GH100 chip with 80,000 million transistors on an 814 mm² die. The database shows the H200 NVL holds a 100th percentile ranking among all GPUs, while the Radeon 820M sits at the 50th percentile. This analysis breaks down the benchmark data, architectural differences, and use-case strengths for each.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 820M and the NVIDIA H200 NVL. The Radeon 820M has no recorded benchmark scores in the database, with an average benchmark score of 0. The H200 NVL, in contrast, has one recorded benchmark: a Geekbench OpenCL score of 334,891. This single data point places the H200 NVL in the 100th percentile of all GPUs, meaning it outperforms virtually every other recorded GPU in that test.

Without direct comparison data, the nearest rivals for the H200 NVL provide the only quantitative benchmark context. The NVIDIA B200 scores 345,482, which is 3.1% higher than the H200 NVL. The AMD Instinct MI300X scores 317,994, which is 5.3% lower. The NVIDIA B300 SXM6 AC scores 369,831, which is 9.4% higher. The NVIDIA L40S scores 295,763, which is 13.2% lower. These deltas show the H200 NVL sits in the upper tier of server accelerators, competitive with the B200 and MI300X, though slightly behind the newer B300 variant.

The Radeon 820M's lack of recorded scores means the database provides no quantitative head-to-head comparison. The performance gap between an integrated 15 W part and a 600 W server accelerator is implied by the architectural and specification differences, but no benchmark numbers confirm it.

Architecture Differences

The architectural split between these two GPUs is fundamental. The Radeon 820M uses AMD's RDNA 3.5 architecture, part of the Navi III IGP generation for Strix Point Mobile. It is fabricated on TSMC's 4 nm process. The H200 NVL uses NVIDIA's Hopper architecture, part of the Server Hopper (Hxx) generation, on TSMC's 5 nm process. The transistor counts differ enormously: the Radeon 820M's transistor count is listed as unknown, while the H200 NVL packs 80,000 million transistors into an 814 mm² die, with a transistor density of 98.3 million per square millimeter.

The Radeon 820M features 128 shading units, 8 texture mapping units, 4 render output units, and 2 ray tracing cores. It has no tensor cores. Its clock speeds run from a 400 MHz base to a 2800 MHz boost. The H200 NVL has 16,896 shading units, 528 texture mapping units, 24 render output units, and 528 tensor cores. Its clocks are lower: 1365 MHz base and 1785 MHz boost. The H200 NVL does not list ray tracing cores.

Memory architecture is another major separator. The Radeon 820M uses system shared memory, with size, type, and bus width all listed as "System Shared" and bandwidth as "System Dependent". The H200 NVL uses 141 GB of HBM3e memory on a 6144 bit bus, with 4.89 TB/s of bandwidth. The Radeon 820M's memory clock is "System Shared" while the H200 NVL runs at 1593 MHz with 6.4 Gbps effective.

Compute throughput reflects the scale difference. The Radeon 820M delivers 716.8 GFLOPS FP32 performance and 716.8 GFLOPS FP16 (1:1 ratio). The H200 NVL delivers 60.32 TFLOPS FP32 and 120.6 TFLOPS FP16 (2:1 ratio). Pixel rates are 11.20 GPixel/s for the Radeon and 42.84 GPixel/s for the H200. Texture rates are 22.40 GTexel/s versus 942.5 GTexel/s.

The H200 NVL supports PCIe 5.0 x16, while the Radeon 820M uses PCIe 4.0 x8. The H200 NVL has no display outputs, while the Radeon's outputs are portable device dependent. API support also differs: the Radeon supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H200 lists N/A for all three APIs, reflecting its compute-focused server role.

Where Each One Wins

The Radeon 820M's strengths lie in its integrated nature and low power envelope. At 15 W TDP with no power connectors, it fits into portable devices as an IGP. Its PCIe 4.0 x8 interface and system shared memory make it a flexible part for mobile platforms. Its ray tracing cores and DirectX 12 Ultimate support indicate it can handle graphics workloads, though the database provides no benchmark scores to quantify this capability. Its 50th percentile ranking suggests it sits at the middle of the GPU performance distribution.

The H200 NVL wins decisively in raw compute. Its 100th percentile ranking, 334,891 Geekbench OpenCL score, and 60.32 TFLOPS FP32 performance place it at the top of the database. Its 141 GB of HBM3e memory with 4.89 TB/s bandwidth and 528 tensor cores make it a server-focused accelerator for large-scale compute tasks. Its 600 W TDP, 8-pin EPS power connector, and 1000 W suggested PSU reflect its data center role. Its dual-slot design and dimensions of 267 mm by 111 mm require server chassis installation.

The database shows no overlap in their intended workloads. The Radeon 820M is a graphics-capable integrated part for mobile devices. The H200 NVL is a headless compute accelerator with no display outputs, designed for deployment in servers where graphics output is unnecessary.
