Architecture Differences

The Radeon 680M uses the Rembrandt+ chip with RDNA 2.0 architecture, positioned as a Navi II IGP for Rembrandt Mobile. The NVIDIA H20 uses the GH100 chip with Hopper architecture, classified as Server Hopper (Hxx). These are fundamentally different design philosophies: one is an integrated graphics solution for mobile systems, the other is a server-grade accelerator module.

Manufacturing processes differ between the two. The Radeon 680M is built on a 6 nm process, while the NVIDIA H20 uses a 5 nm process, both at TSMC. The transistor counts reflect the scale difference: 13,100 million transistors for the Radeon 680M versus 80,000 million for the NVIDIA H20. Die size follows the same pattern, with the Radeon at 208 mm² and the NVIDIA H20 at 814 mm². The resulting transistor densities are 63.0M per mm² for AMD and 98.3M per mm² for NVIDIA, indicating the H20 packs transistors more densely.

The Radeon 680M includes 12 ray tracing cores, while the NVIDIA H20 lists no ray tracing cores in its specifications. The NVIDIA H20 instead carries 312 tensor cores, a feature the Radeon 680M does not include. This difference points to divergent workload targets: the Radeon 680M focuses on graphics rendering with ray tracing support, while the NVIDIA H20 emphasizes tensor operations for compute-heavy tasks.

Clock behavior also differs. The Radeon 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The NVIDIA H20 has a lower base clock of 1830 MHz and a boost clock of 1980 MHz. Despite lower clocks, the NVIDIA H20 achieves far higher throughput due to its massive core count.

Memory architecture is another major split. The Radeon 680M relies on system shared memory with system dependent bandwidth. The NVIDIA H20 uses dedicated HBM3 memory: 96 GB on a 6144 bit bus with 4.03 TB/s bandwidth. The memory clock for the H20 is listed as 1313 MHz with 5.3 Gbps effective speed, while the Radeon 680M has no dedicated memory clock.

Power and physical format differ substantially. The Radeon 680M has a 50 W TDP and is an IGP with no power connectors. The NVIDIA H20 has a 500 W TDP, comes as an SXM Module, and the database suggests a 900 W power supply. The Radeon 680M uses a PCIe 4.0 x8 interface, while the NVIDIA H20 uses PCIe 5.0 x16.

Where Each One Wins

The Radeon 680M wins in the graphics rendering domain. Its recorded benchmarks include 3DMark Steel Nomad DX12 with a score of 378, Geekbench OpenCL with 23468, and Geekbench Vulkan with 21965.

Its nearest rivals, including the GeForce GTX 580, RTX 2060, RTX 3050 OEM, and RX 7600, all cluster within 0.7% of its average score, indicating the 680M performs at a level comparable to those discrete graphics cards.

The NVIDIA H20 wins in raw compute capacity. Its 39.54 TFLOPS FP32 performance and 79.07 TFLOPS FP16 performance dwarf the Radeon 680M's 3.379 TFLOPS FP32 and 6.758 TFLOPS FP16. The H20's 4.03 TB/s memory bandwidth and 96 GB HBM3 capacity serve workloads that require enormous data movement, far beyond what system shared memory can provide. The H20 sits at the 50th percentile among all GPUs, but this percentile is based on no recorded benchmark scores, so it reflects the database's incomplete data for this product rather than measured performance.

The Radeon 680M wins on integration and flexibility. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for consumer graphics applications. Its display outputs are portable device dependent, meaning it can drive screens in mobile systems. The NVIDIA H20 has no display outputs at all, confirming its role as a compute accelerator rather than a graphics card.

The NVIDIA H20 wins on memory capacity and bandwidth. The 96 GB HBM3 configuration with 6144 bit bus width provides 4.03 TB/s, a figure that system shared memory cannot approach. The Radeon 680M's memory bandwidth is listed as system dependent, meaning its performance varies with the host system's memory configuration.

The Radeon 680M has three recorded benchmark scores. In 3DMark Steel Nomad DX12, it scores 378. In Geekbench OpenCL, it scores 23468. In Geekbench Vulkan, it scores 21965. These scores contribute to its average benchmark score of 15270 and its 57th percentile ranking among all GPUs.

The NVIDIA H20 has no recorded benchmark scores. Its average benchmark score is 0, and its percentile ranking is 50. The absence of scores means the database cannot confirm its performance through the same measurement methods used for the Radeon 680M.

The nearest rival data for the Radeon 680M provides context for its performance. The NVIDIA GeForce GTX 580 has an average score of 15283, placing it 0.1% ahead of the 680M. The NVIDIA GeForce RTX 2060 has an average score of 15290, also 0.1% ahead. The NVIDIA GeForce RTX 3050 OEM has an average score of 15199, putting it 0.5% behind the 680M. The AMD Radeon RX 7600 has an average score of 15171, putting it 0.7% behind. This tight clustering suggests the 680M delivers performance in line with these discrete graphics cards, despite being an integrated solution.

The NVIDIA H20 has no nearest rival data recorded. Its performance can only be inferred from its specifications, which show a compute-oriented design with massive core counts and memory bandwidth.

The Verdict

The data indicates two products built for different purposes. The AMD Radeon 680M is an integrated graphics processor with measured benchmark scores, DirectX 12 Ultimate support, and ray tracing cores. Its average benchmark score of 15270 places it in the 57th percentile among all GPUs, and its nearest rivals cluster within 0.7% of its performance. This positions it as a capable graphics solution for mobile systems, competitive with several discrete GPUs from previous generations.

The NVIDIA H20 is a server accelerator with no recorded benchmark scores. Its specifications describe a compute-focused design: 9984 shading units, 312 tensor cores, 96 GB HBM3 memory, and 4.03 TB/s bandwidth. Its FP32 performance of 39.54 TFLOPS and FP16 performance of 79.07 TFLOPS indicate substantial compute capacity, but the database contains no measured results to confirm real-world performance. Its lack of display outputs and API support for graphics libraries confirms its role as a compute device rather than a graphics card.

The Radeon 680M suits applications requiring graphics rendering, ray tracing, and API compatibility. The NVIDIA H20 suits applications requiring large memory capacity, high bandwidth, and tensor operations. The 50th percentile ranking for the H20, based on no recorded scores, does not reflect its specification-level capabilities. The 57th percentile ranking for the Radeon 680M reflects actual measured performance across three benchmark tests.

The recorded data shows no direct competition between these products. Their specifications place them in different market segments, with different power envelopes, memory systems, and feature sets. The Radeon 680M delivers verified graphics performance at 50 W. The NVIDIA H20 delivers specification-level compute capacity at 500 W, pending benchmark confirmation. The choice between them depends on whether the workload demands graphics rendering or compute acceleration, as the data provides no evidence that either product can substitute for the other.
