AMD Ryzen Z2 GPU vs NVIDIA H100 PCIe 96 GB Comparison

Where Each One Wins

The AMD Ryzen Z2 GPU and NVIDIA H100 PCIe 96 GB occupy opposite ends of the hardware spectrum, and the benchmark data reflects that divide clearly. The Ryzen Z2 GPU is a 28 W console-class part built for low-power, integrated-style deployment. The H100 PCIe 96 GB is a 700 W server accelerator. There is no overlap in their intended workloads, and the recorded data shows each product winning in entirely separate domains.

The Ryzen Z2 GPU wins in power efficiency and portability. Its thermal design power is 28 W, a figure that allows it to operate without any power connectors, relying solely on slot or board power. The H100 PCIe 96 GB requires an 8-pin EPS connector and a suggested power supply of 1100 W. The Ryzen Z2 GPU also includes a display output, a single USB Type-C port, while the H100 PCIe 96 GB has no display outputs at all. Any workload that requires driving a display falls to the Ryzen Z2 GPU by default.

The H100 PCIe 96 GB wins in raw compute throughput, memory capacity, and memory bandwidth. Its FP32 output is 62.08 TFLOPS versus 8.294 TFLOPS for the Ryzen Z2 GPU. Its FP16 output reaches 248.3 TFLOPS using a 4:1 ratio, while the Ryzen Z2 GPU delivers 8.294 TFLOPS at a 1:1 ratio. The H100 PCIe 96 GB carries 96 GB of HBM3 memory on a 5120-bit bus for 3.36 TB/s of bandwidth. The Ryzen Z2 GPU has 16 GB of LPDDR5X on a 128-bit bus for 119.9 GB/s.

The data positions the Ryzen Z2 GPU as a solution for edge rendering, lightweight graphics, and power-constrained systems. The H100 PCIe 96 GB is positioned for server-side compute, large model inference, and high-throughput tensor workloads. Neither product encroaches on the other's territory.

Architecture Differences

The two GPUs share a foundry, TSMC, but little else. The Ryzen Z2 GPU uses a 4 nm process with 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6 million per square millimeter. The H100 PCIe 96 GB uses a 5 nm process with 80,000 million transistors on an 814 mm² die, for a density of 98.3 million per square millimeter. The Ryzen Z2 GPU packs more transistors per area, but the H100 PCIe 96 GB has over three times the total transistor count.

The architectural generation differs completely. The Ryzen Z2 GPU is built on RDNA 3.0 with the Hawk Point chip, classified as a Console GPU from AMD. The H100 PCIe 96 GB uses the GH100 chip on the Hopper architecture, classified as a Server Hopper part. The Ryzen Z2 GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H100 PCIe 96 GB lists no DirectX, OpenGL, or Vulkan support in the database, reflecting its compute-first design.

Compute resources differ by an order of magnitude. The Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The H100 PCIe 96 GB has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. The H100 PCIe 96 GB has no listed ray tracing cores, while the Ryzen Z2 GPU has no listed tensor cores.

Memory architecture is another major split. The Ryzen Z2 GPU uses 16 GB of LPDDR5X with a 128-bit bus. The H100 PCIe 96 GB uses 96 GB of HBM3 with a 5120-bit bus. The H100 PCIe 96 GB memory clock runs at 1313 MHz with 5.3 Gbps effective, while the Ryzen Z2 GPU memory runs at 937 MHz with 7.5 Gbps effective. Despite the lower effective rate, the H100 PCIe 96 GB achieves 3.36 TB/s because of its enormous bus width.

Clock behavior also differs. The Ryzen Z2 GPU has a base clock of 800 MHz and a boost of 2700 MHz, a wide dynamic range suited to power saving. The H100 PCIe 96 GB has a base clock of 1665 MHz and a boost of 1837 MHz, a narrow range typical of a high-power part already running near its ceiling.

The H100 PCIe 96 GB is a dual-slot card measuring 268 mm in length and 111 mm in height, with a PCIe 5.0 x16 interface. The Ryzen Z2 GPU has no listed dimensions, slot width, or bus interface, consistent with a compact embedded or mobile-class part. The power connectors field for the Ryzen Z2 GPU reads "None", while the H100 PCIe 96 GB uses an 8-pin EPS connector.

Head-to-Head Benchmarks

The database records no shared benchmark suites for these two products, so direct score comparisons are not available. The specifications themselves provide the measurable differences.

The largest single gap is in texture rate. The H100 PCIe 96 GB delivers 969.9 GTexel/s, which is 7.5 times the 129.6 GTexel/s of the Ryzen Z2 GPU. The pixel rate reverses the trend. The Ryzen Z2 GPU achieves 86.40 GPixel/s, while the H100 PCIe 96 GB achieves 44.09 GPixel/s. The Ryzen Z2 GPU nearly doubles the pixel throughput despite having only 32 ROPs versus 24 on the H100 PCIe 96 GB. This reflects the RDNA 3.0 design prioritizing rasterization efficiency for graphics workloads.

FP32 throughput shows a 7.5 times advantage for the H100 PCIe 96 GB, 62.08 TFLOPS versus 8.294 TFLOPS. FP16 throughput shows a larger relative gap. The H100 PCIe 96 GB reaches 248.3 TFLOPS using a 4:1 ratio, while the Ryzen Z2 GPU reaches 8.294 TFLOPS at a 1:1 ratio. The H100 PCIe 96 GB holds a 30 times advantage in FP16 throughput, a critical metric for AI inference and training workloads.

Memory bandwidth shows the most extreme difference. The H100 PCIe 96 GB provides 3.36 TB/s, which is 28 times the 119.9 GB/s of the Ryzen Z2 GPU. The memory capacity difference is 6 times, 96 GB versus 16 GB. Both figures favor the H100 PCIe 96 GB for large dataset residency and high-bandwidth access patterns.

Power consumption is the reverse. The Ryzen Z2 GPU operates at 28 W, which is 25 times lower than the 700 W of the H100 PCIe 96 GB. The suggested power supply for the H100 PCIe 96 GB is 1100 W, reinforcing its infrastructure requirements. The Ryzen Z2 GPU requires no external power connectors.

Transistor density favors the Ryzen Z2 GPU. It reaches 142.6 million transistors per square millimeter, compared to 98.3 million for the H100 PCIe 96 GB. The 4 nm process enables this density advantage, but the H100 PCIe 96 GB compensates with a much larger die and total transistor budget.

The release timeline also differs. The H100 PCIe 96 GB was released on 2023-03-20, while the Ryzen Z2 GPU was released on 2024-12-31. The H100 PCIe 96 GB lists its predecessor as Server Ada and its successor as Server Blackwell. The Ryzen Z2 GPU lists no predecessor or successor.

The Verdict

The recorded data supports a simple selection rule. Choose the AMD Ryzen Z2 GPU when the workload requires graphics output, low power consumption, or compact deployment. Its 28 W power draw, single USB Type-C display output, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 make it suitable for console-class rendering and power-sensitive systems. Its 86.40 GPixel/s pixel rate exceeds that of the H100 PCIe 96 GB, so it holds an advantage in pure rasterization throughput.

Choose the NVIDIA H100 PCIe 96 GB when the workload demands maximum compute throughput, large memory capacity, or tensor acceleration. Its 62.08 TFLOPS FP32 and 248.3 TFLOPS FP16 outputs, 96 GB of HBM3 memory, and 3.36 TB/s bandwidth place it in a different performance class. The 528 tensor cores provide dedicated hardware for matrix operations, while the Ryzen Z2 GPU has no tensor core count listed.

The percentile ranking for both products is identical at 50, which reflects the absence of overlapping benchmark data rather than comparable performance. The database does not provide nearest rivals or head-to-head benchmark results for either product. Users should treat the two as complementary rather than competitive. One is a low-power graphics solution with a display path. The other is a high-power server accelerator without display output. The architecture, memory system, and compute resources confirm that these products serve separate markets.
