AMD Steam Machine GPU vs NVIDIA H100 SXM5 94 GB Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for these two parts. The database shows no wins for either GPU in a shared test suite, and no benchmark scores are available for either unit. This is an unusual situation, as most GPU comparisons in the database include at least a few synthetic or gaming tests. Both parts fall at the 50th percentile versus all GPUs in the database, but that figure is based on their own separate performance distributions, not on any comparative testing between them.

What the data does show is a massive disparity in raw compute output. The NVIDIA H100 SXM5 94 GB delivers 66.91 TFLOPS of FP32 performance, while the AMD Steam Machine GPU delivers 17.56 TFLOPS. That puts the H100 roughly 3.8 times ahead in single-precision floating-point work. In FP16, the gap widens dramatically. The H100 reaches 267.6 TFLOPS using its 4:1 ratio, while the AMD part manages 17.56 TFLOPS in a 1:1 configuration. The H100 is approximately 15.2 times faster in half-precision throughput. These figures point to entirely different performance classes, even though the database has no direct benchmark runs to confirm them in practice.

The memory subsystem tells a similar story. The H100 has 94 GB of HBM3 memory on a 5120-bit bus, delivering 3.36 TB/s of bandwidth. The AMD Steam Machine GPU has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s. The H100 provides roughly 11.7 times the memory bandwidth and about 11.75 times the capacity. Those are not incremental differences; they represent different orders of magnitude in data movement capability.

Texture throughput also favors the H100 heavily. It produces 1,045.4 GTexel/s compared to the AMD part's 274.4 GTexel/s, a 3.8 times advantage. Pixel rate is the one category where the AMD GPU leads. It produces 156.8 GPixel/s versus 47.52 GPixel/s for the H100. That is a 3.3 times advantage for the Steam Machine GPU, and it reflects the fundamentally different design goals of the two chips.

Architecture Differences

The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The chip is manufactured on a 6 nm process at TSMC and contains 13,300 million transistors on a 204 mm² die. That works out to a transistor density of 65.2 million transistors per square millimeter.

The NVIDIA H100 SXM5 94 GB uses the GH100 chip built on Hopper architecture. It belongs to the Server Hopper (Hxx) generation. The chip is manufactured on a 5 nm process at TSMC and contains 80,000 million transistors on an 814 mm² die. That gives a transistor density of 98.3 million transistors per square millimeter. The H100 packs roughly 6 times the transistor count on a die that is about 4 times larger, and it does so with a higher transistor density despite the smaller process node.

Compute resources differ substantially. The AMD GPU has 1,792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. It has no tensor cores listed. The H100 has 16,896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores. It has no ray tracing cores listed. The H100 has nearly 9.4 times the shading units and 4.7 times the TMUs, but the AMD part has 2.7 times the ROPs. The H100's tensor core count is a defining feature, and the AMD part has no equivalent hardware in the database.

Clock speeds also differ in an interesting way. The AMD GPU has a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. Its memory runs at 2250 MHz with 18 Gbps effective. The H100 has a base clock of 1350 MHz and a boost clock of 1980 MHz, with no game clock listed. Its memory runs at 1313 MHz with 5.3 Gbps effective. The AMD part runs its cores at higher frequencies, but the H100 compensates with far more execution units and a much wider memory interface.

Power and physical configuration reflect their intended environments. The AMD Steam Machine GPU has a TDP of 110 W, requires no external power connectors, and has no listed slot width or bus interface. The H100 is a 700 W SXM module that uses an 8-pin EPS power connector and requires a suggested PSU of 1100 W. It connects via PCIe 5.0 x16. The AMD part has display outputs including one HDMI 2.1a port and one DisplayPort 2.1 port. The H100 has no display outputs at all.

Where Each One Wins

The AMD Steam Machine GPU wins in pixel throughput. Its 156.8 GPixel/s pixel rate is 3.3 times higher than the H100's 47.52 GPixel/s. This is a direct consequence of its 64 ROPs versus the H100's 24 ROPs. For rendering workloads that are fill-rate limited, such as rasterized game scenes at high resolutions, the AMD part has a structural advantage. It also wins on clock speed, with a 2450 MHz boost clock versus 1980 MHz for the H100, and a 2250 MHz game clock where the H100 has no equivalent figure.

The AMD part also wins on physical practicality. It consumes 110 W, requires no external power connectors, has a 156 mm length, a 152 mm height, and a 162 mm width. It offers display outputs, which the H100 lacks entirely. The H100 requires 700 W, an 8-pin EPS connector, and a suggested PSU of 1100 W. It is an SXM module with no listed dimensions and no display capability.

The NVIDIA H100 SXM5 94 GB wins in every compute-heavy category. Its FP32 throughput of 66.91 TFLOPS is 3.8 times the AMD part. Its FP16 throughput of 267.6 TFLOPS is 15.2 times the AMD part. Its texture rate of 1,045.4 GTexel/s is 3.8 times the AMD part. Its memory bandwidth of 3.36 TB/s is 11.7 times the AMD part. Its memory capacity of 94 GB is 11.75 times the AMD part. Its 528 tensor cores give it a dedicated path for matrix math that the AMD GPU cannot match.

The H100 also wins on sheer scale of compute resources. It has 16,896 shading units versus 1,792 for the AMD part. It has 528 TMUs versus 112. It has 80,000 million transistors versus 13,300 million. It uses a larger die at 814 mm² versus 204 mm², and it achieves a higher transistor density at 98.3 million per square millimeter versus 65.2 million.

The AMD part has the newer release date. It is listed as released on 2026-06-28, while the H100 is listed as released on 2023-03-20. Both parts are marked as Active in production status. The AMD part has no predecessor or successor listed, while the H100 lists Server Ada as its predecessor and Server Blackwell as its successor.

The Verdict

The data describes two GPUs with almost no overlap in purpose. The AMD Steam Machine GPU is a compact, low-power console part with display outputs, a 110 W TDP, and 8 GB of memory. The NVIDIA H100 SXM5 94 GB is a server accelerator with no display outputs, a 700 W TDP, and 94 GB of HBM3. Anyone choosing between them based on the database should consider which workload they actually need to run.

For rasterized rendering and game-style workloads, the AMD part has the structural advantages. It has 3.3 times the pixel rate, higher clock speeds, and a power envelope that does not require a dedicated 1100 W PSU. Its 64 ROPs are a genuine asset for fill-rate-bound scenes. It also has display outputs, making it usable in a conventional video output scenario.

For compute workloads, the H100 is in a different class. Its 66.91 TFLOPS FP32 and 267.6 TFLOPS FP16 throughput, combined with 3.36 TB/s of memory bandwidth and 94 GB of capacity, make it suitable for large-scale numerical work. Its 528 tensor cores provide dedicated hardware for matrix operations. The AMD part has no tensor core equivalent in the database.

The 50th percentile ranking for both parts against all GPUs suggests that each sits in the middle of the overall performance distribution, but that ranking does not reflect the massive gap in raw compute between them. The H100 is 3.8 times faster in FP32, 15.2 times faster in FP16, and 11.7 times faster in memory bandwidth. The AMD part is 3.3 times faster in pixel rate. These are not competing products. The database shows a console GPU and a server accelerator that happen to share the GPU label.
