AMD Steam Machine GPU vs NVIDIA RTX PRO 2000 Blackwell Comparison

Head-to-Head Benchmarks

The available benchmark data shows a clear overall victory for the NVIDIA RTX PRO 2000 Blackwell, but the comparison is not a complete sweep because the AMD Steam Machine GPU has no recorded benchmark scores in the database. The AMD card sits at the 50th percentile of all GPUs with an average benchmark score of 0, meaning no measurements exist to directly compare its performance against the NVIDIA card. The RTX PRO 2000 Blackwell, by contrast, holds the 70th percentile with an average benchmark score of 25269 across ten recorded tests.

The NVIDIA card's strongest recorded result comes from the Geekbench Vulkan test, where it scores 113865. Its Geekbench OpenCL result is close behind at 106087, indicating that the card delivers comparable performance across both API frameworks. In 3DMark Steel Nomad DX12, the RTX PRO 2000 Blackwell records 2374.5, a modest score that suggests the card is not primarily optimized for high-end DX12 gaming workloads. The Passmark suite shows a mixed profile: the G3D score of 20049 is the second-highest recorded result, while the GPU compute score of 8396 demonstrates strong parallel processing capability. DirectX 9 and DirectX 11 scores, at 241 and 174 respectively, are higher than the DirectX 12 score of 80, which indicates that the card's driver and hardware combination favors older API paths for certain workloads. The G2D score of 1303 shows basic 2D performance is adequate but not exceptional.

Since the AMD Steam Machine GPU has no benchmark entries, the head-to-head comparison relies entirely on the NVIDIA card's recorded performance relative to its nearest rivals. The RTX PRO 2000 Blackwell sits 1.4% behind the AMD Radeon RX 6700M, 1.8% behind the AMD Radeon Pro W5700, and 1.8% behind the NVIDIA GeForce RTX 3080 Ti Mobile. It sits 2% ahead of the NVIDIA RTX A5000 Mobile. These margins are tight, with all four rivals falling within a 3.8 percentage point band around the RTX PRO 2000 Blackwell's average score. The data shows that this card competes directly with mobile and workstation parts from the previous generation, not with flagship desktop cards.

Where Each One Wins

The AMD Steam Machine GPU cannot claim a single benchmark win because the database contains no recorded scores for it. Every comparison against the NVIDIA card is therefore one-sided, with the RTX PRO 2000 Blackwell having all ten recorded results. The NVIDIA card's wins are distributed across different workload types: Vulkan and OpenCL compute tests show strong performance, while the DirectX 12 Steel Nomad test shows a more moderate result. The Passmark suite reveals that the card's strengths lie in G3D rendering and GPU compute rather than in legacy DirectX paths, with the DirectX 12 score being the lowest at 80.

For the AMD card, the lack of benchmark data means its potential strengths must be inferred from its specifications. The AMD Steam Machine GPU has a higher pixel rate of 156.8 GPixel/s compared to the NVIDIA card's 93.94 GPixel/s, and a higher texture rate of 274.4 GTexel/s versus 266.2 GTexel/s. These figures suggest fill-rate-bound workloads could favor the AMD card, but no benchmark data confirms this. The AMD card also has a higher boost clock of 2450 MHz versus 1957 MHz, and a higher base clock of 1720 MHz versus 982 MHz. However, without recorded scores, the database cannot verify whether these clock advantages translate into actual performance wins.

Architecture Differences

The two GPUs come from different architectural generations and use different process nodes. The AMD Steam Machine GPU uses the RDNA 3.0 architecture on a 6 nm TSMC process, with the Navi 33 chip and the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The NVIDIA RTX PRO 2000 Blackwell uses the Blackwell 2.0 architecture on a 5 nm TSMC process, with the GB206 chip and no recorded codename. It belongs to the Blackwell PRO W (x000) generation.

The transistor counts differ substantially. The NVIDIA chip packs 21,900 million transistors on a 181 mm² die, giving a transistor density of 121.0M per mm². The AMD chip contains 13,300 million transistors on a larger 204 mm² die, for a density of 65.2M per mm². The NVIDIA chip achieves higher density through its smaller process node and more compact die.

Memory configurations also diverge. The AMD card uses 8 GB of GDDR6 memory, while the NVIDIA card uses 16 GB of GDDR7 memory. Both use a 128-bit bus and deliver identical bandwidth of 288.0 GB/s. The memory clock is effectively the same at 18 Gbps for both, though the NVIDIA card's physical memory clock is 1125 MHz versus 2250 MHz for the AMD card, reflecting the different memory technologies.

The compute resource allocation differs significantly. The NVIDIA card has 4352 shading units, 136 texture mapping units, and 48 render output units. It also includes 34 RT cores and 136 tensor cores. The AMD card has 1792 shading units, 112 TMUs, and 64 ROPs, with 28 RT cores and no tensor cores. Despite having fewer shading units, the AMD card achieves a higher FP32 throughput of 17.56 TFLOPS versus 17.03 TFLOPS for the NVIDIA card, and a higher FP16 throughput at the same 1:1 ratio. The NVIDIA card's advantage lies in its tensor cores, which enable AI-accelerated workloads that the AMD card cannot perform.

The pixel rate favors the AMD card at 156.8 GPixel/s versus 93.94 GPixel/s, while the texture rate is close: 274.4 GTexel/s for AMD versus 266.2 GTexel/s for NVIDIA. The NVIDIA card has a dual-slot form factor, while the AMD card's slot width is not recorded. Both use no external power connectors, but the NVIDIA card has a suggested PSU rating of 250 W, while the AMD card has no suggested PSU rating. The NVIDIA card draws 70 W TDP, while the AMD card draws 110 W TDP.

Display outputs differ: the AMD card offers one HDMI 2.1a and one DisplayPort 2.1, while the NVIDIA card offers four mini-DisplayPort 2.1b outputs. The NVIDIA card uses a PCIe 5.0 x8 bus interface, while the AMD card's bus interface is not recorded. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data shows that the NVIDIA RTX PRO 2000 Blackwell is the only card in this comparison with recorded performance measurements. Its average benchmark score of 25269 places it at the 70th percentile of all GPUs, and its nearest rivals are all within 2% of its score. The AMD Steam Machine GPU has no benchmark data and sits at the 50th percentile with an average score of 0, which means the database cannot confirm any performance level for it.

For users seeking a card with verified compute and rendering performance, the RTX PRO 2000 Blackwell is the clear choice based on recorded data. Its 16 GB of GDDR7 memory doubles the AMD card's 8 GB GDDR6 capacity, and its tensor cores enable AI workloads that the AMD card cannot handle. The NVIDIA card also draws less power at 70 W versus 110 W, and it offers four display outputs versus two.

The AMD Steam Machine GPU does hold advantages in raw specification terms: higher pixel rate, higher texture rate, higher FP32 and FP16 throughput, and higher clock speeds. Its larger die and lower transistor density indicate a less compact design, but its 6 nm process still delivers competitive performance on paper. However, without benchmark scores, these specifications cannot be validated against actual workloads.

The database records the RTX PRO 2000 Blackwell as an active product with a release date of 2025-08-10, while the AMD Steam Machine GPU is also active with a release date of 2026-06-28. The NVIDIA card has a predecessor listed as Workstation Ada, while the AMD card has no predecessor or successor. Users needing verified performance should select the NVIDIA card; users requiring the AMD card's specific display outputs or higher fill rates should rely on its specification sheet, since no measured data exists.
