AMD Steam Machine GPU vs NVIDIA H100 NVL 94 GB Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Steam Machine GPU or the NVIDIA H100 NVL 94 GB. Both entries show an average benchmark score of 0, and the head-to-head benchmark data is empty. Consequently, the direct numeric comparison of performance in synthetic workloads cannot be established from the available records.

What can be compared from the documented specifications is the theoretical compute ceiling. The NVIDIA H100 NVL 94 GB delivers 60.32 TFLOPS of FP32 throughput, which is 3.4 times the 17.56 TFLOPS of the AMD Steam Machine GPU. In FP16 workloads, the gap widens dramatically: the H100 NVL reaches 241.3 TFLOPS under its 4:1 ratio, while the Steam Machine GPU sustains 17.56 TFLOPS with a 1:1 ratio. That places the NVIDIA part 13.7 times higher in peak FP16 compute, a difference that reflects the H100's dedicated tensor core array of 528 units, a feature the AMD part lacks entirely.

Texture and pixel throughput tell a more nuanced story. The H100 NVL posts 942.5 GTexel/s against 274.4 GTexel/s for the Steam Machine GPU, a 3.4 times advantage in texture fill. However, the AMD part counters in pixel throughput: 156.8 GPixel/s versus 42.84 GPixel/s, a 3.7 times advantage for the Steam Machine GPU. This inversion stems from the AMD GPU's 64 ROPs compared to only 24 ROPs on the H100, despite the latter having far more shading units overall. The Steam Machine GPU also holds the edge in clock speeds, with a boost of 2450 MHz versus 1785 MHz, which partially compensates for its smaller execution footprint in rasterization-bound tasks.

Memory bandwidth shows an enormous divergence. The H100 NVL accesses 3.94 TB/s across a 6016-bit HBM3 interface, while the Steam Machine GPU manages 288.0 GB/s over a 128-bit GDDR6 bus. The H100's bandwidth is 13.7 times higher, a ratio that matches its FP16 compute advantage. Capacity differences are equally stark: 94 GB versus 8 GB, an 11.75 times difference. Neither card has been assigned a percentile rank above 50 in the database, and both sit at the median of all recorded GPUs, meaning the aggregate performance distribution places them identically despite their specification disparities.

Where Each One Wins

The AMD Steam Machine GPU wins in scenarios that depend on rasterization throughput. Its 64 ROPs and 156.8 GPixel/s pixel rate make it the stronger candidate for traditional frame rendering at high resolutions, where pixel output becomes the limiting factor. The 2450 MHz boost clock also helps latency-sensitive workloads that respond to raw frequency rather than massive parallel arrays. Its 28 ray tracing cores provide hardware acceleration for RT effects, a capability the H100 NVL does not document. Additionally, the Steam Machine GPU includes display outputs (1x HDMI 2.1a and 1x DisplayPort 2.1), meaning it can drive monitors directly, something the H100 NVL cannot do with its no-output configuration. The 110 W TDP also positions it for compact, lower-power systems.

The NVIDIA H100 NVL wins in compute-bound and memory-bound workloads. Its 60.32 TFLOPS FP32 and 241.3 TFLOPS FP16 performance, combined with 528 tensor cores, target matrix-heavy tasks such as neural network training and inference. The 3.94 TB/s memory bandwidth and 94 GB capacity allow it to hold and process datasets far larger than the AMD part's 8 GB pool. Its 528 TMUs produce 942.5 GTexel/s for texture-heavy compute pipelines, and the 6016-bit bus width minimizes data movement bottlenecks. The PCIe 5.0 x16 interface provides a modern host connection, and the 800 W suggested PSU rating indicates a system designed for sustained high-power compute, not efficiency-constrained gaming.

The specification split is clean: the Steam Machine GPU leads in pixel rate, clock speed, and display connectivity; the H100 NVL leads in compute throughput, memory bandwidth, memory capacity, and texture rate. Neither part is a general substitute for the other, as their design objectives diverge at every major subsystem.

Specification Differences

The two GPUs differ across nearly every recorded specification. The AMD Steam Machine GPU uses a 6 nm process and a 204 mm² die with 13,300 million transistors, while the NVIDIA H100 NVL uses a 5 nm process and an 814 mm² die with 80,000 million transistors. Transistor density favors the H100 at 98.3M per mm² versus 65.2M per mm² for the AMD part.

Clock speeds differ substantially: the Steam Machine GPU has a base of 1720 MHz, a boost of 2450 MHz, and a game clock of 2250 MHz; the H100 NVL has a base of 1080 MHz and a boost of 1785 MHz, with no game clock listed. Memory configurations are entirely different: 8 GB GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth versus 94 GB HBM3 on a 6016-bit bus with 3.94 TB/s bandwidth.

Compute unit counts diverge sharply: 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores for AMD versus 16896 shading units, 528 TMUs, 24 ROPs, and 528 tensor cores for NVIDIA. The H100 has no RT core count and the Steam Machine GPU has no tensor core count. Power requirements differ: 110 W TDP with no power connectors for the AMD part versus 400 W TDP with an 8-pin EPS connector and an 800 W suggested PSU for the NVIDIA part.

Physical specifications also differ: the Steam Machine GPU measures 156 mm in length, 152 mm in height, and 162 mm in width; the H100 NVL measures 267 mm in length and 111 mm in height, with no width recorded. The H100 is dual-slot, while the Steam Machine GPU has no slot width recorded. The Steam Machine GPU provides 1x HDMI 2.1a and 1x DisplayPort 2.1 outputs; the H100 NVL provides no outputs. The H100 uses a PCIe 5.0 x16 bus interface, while the Steam Machine GPU has no bus interface recorded.

Architecture Differences

The AMD Steam Machine GPU is built on the RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish. It belongs to the Console GPU (Valve) generation and is manufactured by TSMC on a 6 nm node. Its 13,300 million transistors fit into a 204 mm² die, yielding a density of 65.2M transistors per mm². The architecture emphasizes a balanced mix of shading, texture, and raster hardware, with 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The FP16 throughput matches FP32 at 17.56 TFLOPS with a 1:1 ratio, indicating no specialized half-precision acceleration path. The card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and its display outputs confirm a graphics-oriented role.

The NVIDIA H100 NVL is built on the Hopper architecture with the GH100 chip and belongs to the Server Hopper (Hxx) generation. It is also manufactured by TSMC but on a 5 nm node, with 80,000 million transistors on an 814 mm² die, for a density of 98.3M transistors per mm². The architecture is compute-first: 16896 shading units, 528 TMUs, and 528 tensor cores, with no ray tracing cores listed. The FP16 rate of 241.3 TFLOPS at a 4:1 ratio relative to FP32 indicates a dedicated tensor core pipeline optimized for reduced-precision arithmetic. The H100 NVL has no graphics API support recorded, no display outputs, and a dual-slot server form factor. Its predecessor is listed as Server Ada and its successor as Server Blackwell, placing it within a defined server product lineage. The Steam Machine GPU has no predecessor or successor recorded.

The architectural philosophies are opposite. RDNA 3.0 on the AMD side pairs moderate compute with strong rasterization and display features for a console-class device. Hopper on the NVIDIA side strips away display and graphics API support in favor of massive compute density, tensor acceleration, and high-bandwidth memory. The 3.94 TB/s memory subsystem and 94 GB capacity are the defining features of the H100 NVL, while the 156.8 GPixel/s pixel rate and 28 RT cores define the Steam Machine GPU.

The Verdict

The recorded data points to two different buyers. The AMD Steam Machine GPU is the appropriate choice for systems that need a display-capable, ray-tracing-enabled graphics card with modest power draw. Its 110 W TDP, no power connector requirement, and 156 mm length allow installation in compact chassis. Its 64 ROPs and 2450 MHz boost clock give it a clear advantage in pixel-driven rendering workloads, and its support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 covers standard graphics APIs. The 8 GB GDDR6 memory and 288.0 GB/s bandwidth are sufficient for a console-targeted device but will limit large dataset handling.

The NVIDIA H100 NVL 94 GB is the appropriate choice for server deployments focused on compute acceleration. Its 94 GB HBM3 memory and 3.94 TB/s bandwidth enable working sets that far exceed the AMD part's capacity. The 528 tensor cores and 241.3 TFLOPS FP16 throughput position it for machine learning and scientific computing. The lack of display outputs and graphics API support confirms it is not intended for interactive rendering. The 400 W TDP and 800 W suggested PSU require a server platform designed for high-power accelerators.

Both parts share a median percentile rank of 50 in the database, but that aggregate position obscures their entirely different performance profiles. The Steam Machine GPU wins wherever rasterization, clock speed, or display output matters. The H100 NVL wins wherever raw compute, memory bandwidth, or memory capacity matters. Selecting between them depends entirely on the workload class: graphics output and ray tracing point to the AMD part, while dense compute and large memory pools point to the NVIDIA part.
