Architecture Differences

The two GPUs come from different architectural generations and different design philosophies. The AMD Steam Machine GPU uses the Navi 33 chip built on the RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The chip is fabricated on a 6 nm process at TSMC, integrates 13,300 million transistors on a 204 mm² die, and achieves a transistor density of 65.2 million transistors per square millimeter.

The NVIDIA RTX PRO 5000 Blackwell uses the GB202 chip on the Blackwell 2.0 architecture and belongs to the Blackwell PRO W (x000) generation. It is fabricated on a 5 nm process at TSMC, integrates 92,200 million transistors on a 750 mm² die, and achieves a transistor density of 122.9 million transistors per square millimeter. The NVIDIA chip packs nearly seven times the transistor count onto a die roughly 3.7 times the area, with nearly double the transistor density.

The architectural feature sets diverge sharply. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, with 28 RT cores dedicated to ray tracing. The NVIDIA part supports the same API versions but adds 440 tensor cores alongside its 110 RT cores. The tensor cores are absent entirely from the AMD chip, which has no tensor core count recorded in the database. This difference matters for any workload that relies on tensor operations, such as AI inference or deep learning training, where the NVIDIA architecture has dedicated hardware.

The AMD GPU has no predecessor or successor recorded, while the RTX PRO 5000 Blackwell lists Workstation Ada as its predecessor. This indicates the NVIDIA card continues an established professional product line, whereas the AMD part appears as a single-generation console-specific component.

The RDNA 3.0 architecture in the AMD part is designed for fixed-function console workloads with a modest power envelope. The Blackwell 2.0 architecture in the NVIDIA part targets professional rendering, compute, and AI tasks with a much higher power ceiling. The die size difference alone, 204 mm² versus 750 mm², reflects the scale of the respective design goals.

Specification Differences

The memory subsystems differ in every measurable field. The AMD Steam Machine GPU uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The NVIDIA RTX PRO 5000 Blackwell uses 48 GB of GDDR7 with a 384-bit bus and 1.34 TB/s bandwidth. Memory capacity is six times larger on the NVIDIA card, bus width is three times wider, and bandwidth is over four and a half times higher.

Clock speeds show a closer relationship. The AMD part has a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2450 MHz. The NVIDIA part has a base clock of 1740 MHz and a boost clock of 2377 MHz, with no game clock recorded. The AMD card actually boosts 73 MHz higher, but this advantage is overwhelmed by the NVIDIA card's much larger execution resource pool.

Compute resources show the NVIDIA card's dominance. The AMD part has 1,792 shading units, 112 TMUs, and 64 ROPs. The NVIDIA part has 14,080 shading units, 440 TMUs, and 160 ROPs. That is 7.9 times more shading units, 3.9 times more TMUs, and 2.5 times more ROPs. The pixel rate of 380.3 GPixel/s on the NVIDIA card is 2.4 times the AMD card's 156.8 GPixel/s, and the texture rate of 1,045.9 GTexel/s is 3.8 times higher.

FP32 and FP16 compute are both rated at a 1:1 ratio on each card, but the absolute figures differ enormously. The NVIDIA card delivers 66.94 TFLOPS in both precisions, while the AMD card delivers 17.56 TFLOPS in both. The NVIDIA card is 3.8 times faster in raw floating-point throughput.

Physical specifications also diverge. The AMD part measures 156 mm by 152 mm by 162 mm, while the NVIDIA card measures 267 mm by 111 mm by 40 mm. The AMD part is roughly square and much shorter in length, while the NVIDIA card is a long, thin dual-slot board. The NVIDIA card uses PCIe 5.0 x16, while the AMD part has no bus interface recorded. Display outputs differ as well: the AMD card has one HDMI 2.1a and one DisplayPort 2.1, while the NVIDIA card has four DisplayPort 2.1b outputs.

Power delivery is a major differentiator. The AMD card draws 110 W with no power connectors, meaning it receives all power through its slot. The NVIDIA card draws 300 W, requires a single 16-pin connector, and needs a 700 W suggested PSU. The production status of both cards is Active, but the release dates differ: the NVIDIA card was released on 2025-03-17, while the AMD card is dated 2026-06-28.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, and the wins counter shows 0 for each side. However, the recorded benchmarks for the NVIDIA RTX PRO 5000 Blackwell provide a baseline for its performance tier. In 3DMark Steel Nomad DX12, it scores 9,579.5. In Geekbench OpenCL, it scores 254,116. In Geekbench Vulkan, it scores 282,631. The average across these three tests is 182,109.

The AMD Steam Machine GPU has no benchmark entries at all, meaning the database records no measured performance for it. Its average benchmark score is 0, and its percentile ranking of 50 is based on its position relative to other GPUs in the database, not on any recorded test results. The absence of data is itself informative: the part has not been through the same benchmark suite as the NVIDIA card.

The nearest rivals for the RTX PRO 5000 Blackwell place its performance in context. The NVIDIA A100 SXM4 80 GB scores 183,725, which is 0.9% higher than the RTX PRO 5000 Blackwell. The RTX 5000 Ada Generation scores 184,664, which is 1.4% higher. The GeForce RTX 4090 D scores 178,050, which is 2.3% lower. The A100 SXM4 40 GB scores 187,147, which is 2.7% higher. This cluster of scores, all within a few percentage points of each other, places the RTX PRO 5000 Blackwell in the top tier of professional GPUs in the database.

The Vulkan score of 282,631 is the highest of the three recorded tests for the NVIDIA card, followed by the OpenCL score of 254,116 and the Steel Nomad score of 9,579.5. The Steel Nomad test is a different scale, so direct comparison across tests is not meaningful, but within each test the numbers confirm the card's high-end placement.

Since the AMD part has no scores, no head-to-head win margins can be computed. The comparison is entirely one-sided: the NVIDIA card has recorded data, the AMD card does not. Any analysis of relative performance must rely on the architectural and specification differences, which all favor the NVIDIA card.

Where Each One Wins

The NVIDIA RTX PRO 5000 Blackwell wins on every metric recorded in the database. It delivers 66.94 TFLOPS FP32, which is 3.8 times the AMD card's 17.56 TFLOPS. It delivers 1.34 TB/s memory bandwidth, which is 4.7 times the AMD card's 288.0 GB/s. It has 48 GB of memory, which is six times the AMD card's 8 GB. It has 14,080 shading units, which is 7.9 times the AMD card's 1,792. It has 440 tensor cores, which the AMD card lacks entirely. It has 110 RT cores, which is 3.9 times the AMD card's 28. Its 380.3 GPixel/s pixel rate is 2.4 times higher, and its 1,045.9 GTexel/s texture rate is 3.8 times higher.

The RTX PRO 5000 Blackwell wins in professional and compute-intensive scenarios based on its recorded benchmark scores and its position among its nearest rivals. Its 98th percentile ranking, its average score of 182,109, and its proximity to the A100 SXM4 80 GB and RTX 5000 Ada Generation confirm it belongs in the highest tier of workstation accelerators. Workloads that demand large memory capacity, high bandwidth, tensor core acceleration, and multi-output display support are served by this card. Its four DisplayPort 2.1b outputs support multi-monitor professional setups, while its PCIe 5.0 x16 interface provides high host bandwidth.

The AMD Steam Machine GPU wins in the single category of power efficiency and physical integration. Its 110 W TDP is less than half the NVIDIA card's 300 W TDP, and it requires no power connectors, meaning it can be powered entirely through its slot. Its compact dimensions of 156 mm by 152 mm by 162 mm allow it to fit in a console chassis, whereas the NVIDIA card's 267 mm length requires a full-sized expansion slot. The AMD card also has a higher boost clock at 2450 MHz versus 2377 MHz, though this does not translate into higher compute throughput.

For a fixed-function console application where the GPU is soldered into a sealed system with a 110 W power budget, the AMD Steam Machine GPU is the appropriate component. For any workstation, rendering, compute, or AI workload where the database records performance data, the NVIDIA RTX PRO 5000 Blackwell is the only option with measured results. The data does not support any scenario where the AMD card outperforms the NVIDIA card, because no benchmark results exist for the AMD part and every architectural metric favors the NVIDIA card.
