The Verdict

The data shows two GPUs with fundamentally different purposes. The AMD Radeon 680M is an integrated graphics solution for mobile devices, delivering a 57th percentile ranking across all GPUs. It achieves an average benchmark score of 15,270, placing it within 0.7% of the AMD Radeon RX 7600 and within 0.1% of the NVIDIA GeForce RTX 2060. This indicates it performs competitively with discrete desktop GPUs from several generations ago, despite being an IGP.

The NVIDIA H20 NVL16, however, has no benchmark scores recorded in the database. Its percentile ranking sits at 50, but this is based on an average score of 0, which means it cannot be directly compared to the 680M through recorded measurements. The H20 NVL16 is designed for server workloads, evidenced by its SXM Module form factor, 400 W TDP, and lack of display outputs. It also has no DirectX, OpenGL, or Vulkan API support, confirming it is not intended for client-side graphics rendering.

For users seeking an integrated graphics solution for a portable device, the data shows the AMD Radeon 680M as the clear choice. It has measurable performance data, active production status, and a wide range of API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The H20 NVL16, by contrast, has no recorded graphics benchmarks and no display outputs, making it unsuitable for any traditional graphics workload.

For data center or compute-oriented deployments, the H20 NVL16 offers specifications that point to massive compute capability: 9,984 shading units, 312 tensor cores, 96 GB of HBM3 memory, and 39.54 TFLOPS of FP32 performance. However, without benchmark data, the database cannot confirm how these specifications translate into real-world performance. The 680M, with its 3.379 TFLOPS FP32 and 6.758 TFLOPS FP16, is clearly in a different performance class, but it has the advantage of verifiable measurements.

Head-to-Head Benchmarks

The head-to-head benchmark comparison between these two GPUs is limited because the database contains no common benchmark tests for both. The AMD Radeon 680M has three recorded scores, while the NVIDIA H20 NVL16 has none. This absence of overlapping data means direct numerical comparisons are impossible from the recorded measurements.

The 680M's 3DMark Steel Nomad DX12 score of 378 places it in a position where its nearest rivals include the NVIDIA GeForce GTX 580 with an average score of 15,283 (a 0.1% delta), the NVIDIA GeForce RTX 2060 with 15,290 (0.1% delta), the NVIDIA GeForce RTX 3050 OEM with 15,199 (0.5% delta), and the AMD Radeon RX 7600 with 15,171 (0.7% delta). This grouping shows the 680M sits within a very tight cluster of GPUs, all within 1% of each other. The 680M's average score of 15,270 is 13 points below the GTX 580, 20 points below the RTX 2060, 71 points above the RTX 3050 OEM, and 99 points above the RX 7600. These deltas are small enough to suggest near-parity performance among these five GPUs in aggregate scoring.

The Geekbench OpenCL score of 23,468 for the 680M represents its strongest recorded result, indicating strong compute performance relative to its other metrics. The Vulkan score of 21,965 is slightly lower but still substantial. These two scores, combined with the much lower 3DMark Steel Nomad result, suggest the 680M excels in compute-oriented tasks while being more modest in pure rasterization workloads.

For the H20 NVL16, the absence of benchmarks in the database means there are no wins to report in either direction. The winsA and winsB fields both show 0, confirming no head-to-head tests were recorded. This is consistent with the H20 NVL16's positioning as a server accelerator without display outputs or client graphics APIs.

Specification Differences

The two GPUs differ dramatically across nearly every specification field. The AMD Radeon 680M uses the Rembrandt+ chip on a 6 nm process, while the NVIDIA H20 NVL16 uses the GH100 chip on a 5 nm process. Both are fabricated by TSMC, but the transistor counts differ enormously: the 680M has 13,100 million transistors on a 208 mm² die, while the H20 NVL16 has 80,000 million transistors on an 814 mm² die. Transistor density also differs, with the 680M at 63.0 million transistors per mm² and the H20 NVL16 at 98.3 million per mm².

Clock speeds show the 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz, while the H20 NVL16 has a base clock of 1830 MHz and a boost clock of 1980 MHz. The 680M's higher clocks are notable given its much lower TDP of 50 W versus the H20 NVL16's 400 W.

Memory configurations are entirely different. The 680M uses system-shared memory with a bus width and type also marked as system shared, and bandwidth is system dependent. The H20 NVL16 has 96 GB of HBM3 memory on a 6144-bit bus with 4.03 TB/s bandwidth and a memory clock of 1313 MHz (5.3 Gbps effective).

The compute units differ in scale. The 680M has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores, with no tensor cores. The H20 NVL16 has 9,984 shading units, 312 TMUs, 24 ROPs, no ray tracing cores, and 312 tensor cores. Pixel rates are 70.40 GPixel/s for the 680M versus 47.52 GPixel/s for the H20 NVL16, while texture rates are 105.6 GTexel/s versus 617.8 GTexel/s respectively. FP32 performance is 3.379 TFLOPS for the 680M and 39.54 TFLOPS for the H20 NVL16, and FP16 is 6.758 TFLOPS versus 79.07 TFLOPS.

Power and form factor also differ: the 680M is an IGP with no power connectors and a 50 W TDP, while the H20 NVL16 is an SXM Module with a 400 W TDP and a suggested PSU of 800 W. The 680M uses a PCIe 4.0 x8 interface, while the H20 NVL16 uses PCIe 5.0 x16. Display outputs are portable device dependent for the 680M, while the H20 NVL16 has no outputs.

Architecture Differences

The architectural divide between these two GPUs is substantial. The AMD Radeon 680M is built on RDNA 2.0, which is a graphics-first architecture designed for integrated use in mobile processors. It belongs to the Navi II IGP generation with the codename Rembrandt Mobile. The 680M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it fully capable for modern client-side graphics applications. Its 12 ray tracing cores indicate hardware-accelerated ray tracing support, a feature typically associated with discrete gaming GPUs.

The NVIDIA H20 NVL16 is built on the Hopper architecture, which is compute-first and designed for server deployments. It belongs to the Server Hopper (Hxx) generation. The H20 NVL16 has no DirectX, OpenGL, or Vulkan API support, which means it cannot run traditional graphics workloads at all. Its 312 tensor cores are the defining feature, indicating a focus on AI and deep learning tasks. The lack of ray tracing cores further confirms this is not a graphics-oriented product.

The cache hierarchy also differs implicitly through the architecture: RDNA 2.0 typically relies on a unified L2 cache with a simpler hierarchy suited for graphics, while Hopper includes a larger, more complex cache system optimized for data center compute patterns. The 680M's 6 nm process node from TSMC is one generation behind the H20 NVL16's 5 nm node, but the 680M compensates with higher clock speeds (2000 MHz base, 2200 MHz boost) versus the H20 NVL16's 1830 MHz base and 1980 MHz boost.

The predecessor and successor relationships further illustrate the divergence. The 680M's predecessor is the Vega II IGP and its successor is the Navi III IGP, showing a clear lineage within AMD's integrated graphics lineup. The H20 NVL16's predecessor is Server Ada and its successor is Server Blackwell, placing it within NVIDIA's server accelerator roadmap.

Where Each One Wins

Based on the recorded data, the AMD Radeon 680M wins in every measurable benchmark category because it is the only one with recorded scores. Its 3DMark Steel Nomad DX12 score of 378, Geekbench OpenCL score of 23,468, and Geekbench Vulkan score of 21,965 provide concrete evidence of graphics and compute capability. The 680M also wins in terms of API support, offering DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the H20 NVL16 offers none of these.

The 680M also wins on power efficiency. Its 50 W TDP is one-eighth of the H20 NVL16's 400 W TDP, and its clock speeds are higher despite this massive power difference. The 680M's pixel rate of 70.40 GPixel/s exceeds the H20 NVL16's 47.52 GPixel/s, indicating better rasterization throughput per clock in its designed workload.

The NVIDIA H20 NVL16 wins on raw compute specifications. Its FP32 performance of 39.54 TFLOPS is 11.7 times higher than the 680M's 3.379 TFLOPS. Its FP16 performance of 79.07 TFLOPS is 11.7 times higher than the 680M's 6.758 TFLOPS. The texture rate of 617.8 GTexel/s is 5.9 times higher than the 680M's 105.6 GTexel/s. Memory bandwidth of 4.03 TB/s versus system-dependent bandwidth is also a decisive advantage for workloads that require large data movement.

The H20 NVL16 wins on memory capacity with 96 GB of HBM3 versus system-shared memory for the 680M. It also wins on interface bandwidth with PCIe 5.0 x16 versus PCIe 4.0 x8, and on transistor count with 80,000 million versus 13,100 million.

The use-case split is clear. The 680M is the winner for any scenario requiring display output, graphics rendering, or client-side compute on a portable device. Its integrated form factor, low power draw, and full graphics API support make it suitable for laptops and similar mobile systems. The H20 NVL16 is the winner for server-side compute workloads, particularly those leveraging tensor cores for AI inference or training, where its massive FP16 throughput, large HBM3 memory pool, and high bandwidth are directly applicable. The database shows no overlap in benchmark coverage, so the choice between them depends entirely on whether the workload is client graphics or server compute.
