Architecture Differences

The AMD Steam Machine GPU and the NVIDIA H200 SXM 141 GB represent two fundamentally different design philosophies. The AMD part is built on the RDNA 3.0 architecture using the Navi 33 chip, manufactured on a 6 nm process at TSMC. The NVIDIA part uses the Hopper architecture with the GH100 chip, manufactured on a 5 nm process, also at TSMC. The process node difference contributes to the NVIDIA chip's higher transistor density of 98.3M per mm² compared to the AMD chip's 65.2M per mm².

The transistor counts reveal the scale disparity. The AMD chip packs 13,300 million transistors on a 204 mm² die. The NVIDIA chip contains 80,000 million transistors on an 814 mm² die. This translates into vastly different compute resources. The AMD GPU has 1792 shading units, 112 TMUs, and 64 ROPs. The NVIDIA GPU has 16896 shading units, 528 TMUs, and only 24 ROPs. The NVIDIA's lower ROP count relative to its shading units indicates a compute-oriented design rather than a rasterization-focused one.

The AMD GPU includes 28 ray tracing cores, whereas the NVIDIA GPU does not list RT cores in the data. Instead, the NVIDIA GPU includes 528 tensor cores, which the AMD GPU does not have. This reflects the NVIDIA part's emphasis on AI and deep learning workloads. The AMD GPU's FP16 performance is 17.56 TFLOPS at a 1:1 ratio with FP32, while the NVIDIA GPU achieves 133.8 TFLOPS FP16 at a 2:1 ratio, highlighting its advantage in mixed-precision compute.

Memory architecture differs fundamentally. The AMD GPU uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA GPU uses 141 GB of HBM3e on a 6144-bit bus, delivering 4.89 TB/s. The NVIDIA memory bandwidth is more than an order of magnitude higher. Clock speeds also differ: the AMD GPU has a base clock of 1720 MHz and a boost of 2450 MHz, while the NVIDIA GPU has a base clock of 1500 MHz and a boost of 1980 MHz.

Physical and power characteristics diverge sharply. The AMD GPU has a TDP of 110 W, requires no power connectors, and is designed for a console form factor with dimensions of 156 mm length, 152 mm height, and 162 mm width. The NVIDIA GPU has a TDP of 700 W, uses an 8-pin EPS connector, requires a suggested PSU of 1100 W, and comes as an SXM module with PCIe 5.0 x16 interface. The AMD GPU has display outputs including 1x HDMI 2.1a and 1x DisplayPort 2.1, while the NVIDIA GPU has no display outputs at all.

The Verdict

The data indicates that these two GPUs serve entirely different purposes. The AMD Steam Machine GPU, with its RDNA 3.0 architecture, 17.56 TFLOPS FP32, 288.0 GB/s memory bandwidth, and 110 W TDP, is positioned for console-class gaming with standard graphics API support. The NVIDIA H200 SXM 141 GB, with its Hopper architecture, 66.91 TFLOPS FP32, 133.8 TFLOPS FP16, 4.89 TB/s memory bandwidth, and 700 W TDP, is positioned for server-class compute workloads.

The NVIDIA GPU's FP32 performance is 3.8 times higher than the AMD GPU's. Its FP16 performance is 7.6 times higher. Its memory bandwidth is approximately 17 times higher. However, the NVIDIA GPU has no display outputs and no graphics API support, making it unsuitable for direct rendering tasks. The AMD GPU provides HDMI 2.1a and DisplayPort 2.1 outputs, along with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support.

For gaming-oriented usage, the AMD Steam Machine GPU is the only viable option based on the recorded data. For compute-intensive server workloads, particularly those leveraging tensor cores and FP16 performance, the NVIDIA H200 SXM is the clear choice. The AMD GPU's 64 ROPs versus the NVIDIA GPU's 24 ROPs also indicates that the AMD part is better suited for rasterization tasks, while the NVIDIA part trades that capability for compute throughput.
