AMD Ryzen Z2 Go GPU vs NVIDIA H100 CNX Comparison

Head-to-Head Benchmarks

The recorded database contains no benchmark scores for either the AMD Ryzen Z2 Go GPU or the NVIDIA H100 CNX. Both parts sit at the 50th percentile among all GPUs in the database, with an average benchmark score of zero. The head-to-head comparison table is empty, and neither product has any nearest rivals listed. This means the data cannot show direct performance deltas, win counts, or percentage advantages between the two. What the database does provide is a complete specification sheet for each, allowing a structural comparison rather than a measured performance comparison.

Without benchmark results, the only quantitative comparisons available come from the specification fields. The NVIDIA H100 CNX delivers 53.84 TFLOPS of FP32 throughput against 4.147 TFLOPS for the AMD Ryzen Z2 Go GPU, a factor of roughly 13x. In FP16, the gap widens further: 215.4 TFLOPS versus 8.294 TFLOPS. The texture rate tells a similar story, with the H100 CNX reaching 841.3 GTexel/s compared to 129.6 GTexel/s. The pixel rate, however, favors the AMD part: 86.40 GPixel/s against 44.28 GPixel/s for the H100 CNX. That inversion comes from the H100 CNX having only 24 ROPs while the Ryzen Z2 Go GPU has 32, despite the NVIDIA chip having far more shading units and texture units overall.

Memory bandwidth also diverges sharply. The H100 CNX provides 2.04 TB/s across a 5120-bit HBM2e interface, while the Ryzen Z2 Go GPU manages 102.4 GB/s over a 128-bit LPDDR5 bus. That is a 20x difference in raw bandwidth. The AMD part compensates with lower power draw: 28 W versus 350 W for the NVIDIA chip. The database shows no measured scores, so these specification-derived ratios are the only head-to-head numbers available.

Architecture Differences

The two GPUs come from different architectural lineages and target entirely different market segments. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, classified in the database as a Console GPU under AMD's generation naming. The NVIDIA H100 CNX uses the GH100 chip with Hopper architecture, classified as a Server Hopper part. The process nodes differ: AMD uses a 6 nm TSMC process, while NVIDIA uses a 5 nm TSMC process. Transistor counts reflect the size gap: the AMD die packs 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0M per mm². The NVIDIA die contains 80,000 million transistors on an 814 mm² die, with a density of 98.3M per mm².

The compute layouts diverge substantially. The AMD part has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. It lists no tensor cores. The NVIDIA part has 14,592 shading units, 456 TMUs, 24 ROPs, no ray tracing cores listed, and 456 tensor cores. The NVIDIA chip also has a higher boost clock at 1845 MHz versus 2700 MHz for the AMD part, though the AMD chip starts from a higher base clock of 800 MHz versus 690 MHz. Memory types differ completely: LPDDR5 for AMD, HBM2e for NVIDIA. The AMD part has no power connectors and consumes 28 W, while the NVIDIA card requires an 8-pin EPS connector, is dual-slot, and draws 350 W with a suggested PSU of 750 W.

API support also separates them. The AMD Ryzen Z2 Go GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA H100 CNX lists no DirectX, OpenGL, or Vulkan support in the database, consistent with its server positioning. Display outputs differ as well: the AMD part has one USB Type-C output, while the NVIDIA part has no display outputs at all. The bus interface is PCIe 5.0 x16 for the NVIDIA card; the AMD part lists no bus interface. Physical dimensions appear only for the NVIDIA card: 267 mm in length and 111 mm in height.

Where Each One Wins

Based on the specification data, the AMD Ryzen Z2 Go GPU wins in several categories that matter for compact, power-limited systems. Its 28 W TDP is dramatically lower than the NVIDIA H100 CNX's 350 W. The AMD part achieves a higher pixel rate of 86.40 GPixel/s, which comes from its higher base clock and more ROPs per watt. It also has a higher boost clock at 2700 MHz and a higher base clock at 800 MHz. The AMD part includes ray tracing cores, whereas the NVIDIA part lists none. It supports a full consumer API stack with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it provides a display output via USB Type-C. The AMD chip uses 16 GB of LPDDR5 memory, which is ample for its intended console-class workloads.

The NVIDIA H100 CNX wins decisively in raw compute throughput and memory capacity. Its FP32 performance of 53.84 TFLOPS dwarfs the AMD part's 4.147 TFLOPS. FP16 performance of 215.4 TFLOPS versus 8.294 TFLOPS shows a 26x advantage. The H100 CNX offers 80 GB of HBM2e memory with 2.04 TB/s bandwidth, compared to 16 GB and 102.4 GB/s for the AMD part. The 456 tensor cores provide dedicated matrix math acceleration that the AMD part lacks entirely. Texture rate of 841.3 GTexel/s versus 129.6 GTexel/s gives the NVIDIA chip a 6.5x edge in texture-heavy workloads. The NVIDIA card also has a much larger transistor budget: 80,000 million versus 13,100 million, and a higher transistor density at 98.3M per mm².

The use-case split is clear from the data. The AMD Ryzen Z2 Go GPU suits scenarios where power draw, display output, and consumer API compatibility take priority. The NVIDIA H100 CNX suits scenarios where raw compute, memory bandwidth, and tensor operations dominate.

The Verdict

The database shows two GPUs with no overlapping purpose. The AMD Ryzen Z2 Go GPU is a 28 W console-class part with 16 GB of LPDDR5 memory, a display output, consumer API support, and ray tracing cores. It delivers 4.147 TFLOPS of FP32 and 86.40 GPixel/s of pixel throughput. Its 2700 MHz boost clock and 12 RT cores make it suitable for graphics workloads where power efficiency and compact integration matter. The absence of any power connectors and the single USB Type-C output reinforce its role as an embedded or handheld-oriented processor.

The NVIDIA H100 CNX is a 350 W server accelerator with 80 GB of HBM2e memory, 2.04 TB/s of bandwidth, 456 tensor cores, and 53.84 TFLOPS of FP32. It has no display outputs, no consumer API support listed, and requires an 8-pin EPS connector with a 750 W suggested PSU. Its 267 mm length and dual-slot design indicate a standard server card form factor. The 5 nm process and 80,000 million transistors on an 814 mm² die place it in a completely different performance class.

Given the data, the AMD Ryzen Z2 Go GPU is the appropriate choice for systems requiring low power draw, display connectivity, and standard graphics APIs. The NVIDIA H100 CNX is the appropriate choice for compute-heavy workloads requiring massive memory bandwidth, tensor core acceleration, and high FP16 throughput. The two products do not compete in any recorded benchmark, and the specification sheets confirm they serve disjoint markets. The 50th percentile ranking for both parts reflects the absence of benchmark data rather than any performance equivalence. Buyers should select based on the specification requirements outlined above, as the database provides no measured performance comparison to inform a direct head-to-head decision.
