AMD Steam Machine GPU vs NVIDIA RTX PRO 6000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries between the AMD Steam Machine GPU and the NVIDIA RTX PRO 6000 Blackwell. The AMD Steam Machine GPU has no benchmark scores listed, while the NVIDIA RTX PRO 6000 Blackwell carries a single 3DMark Steel Nomad DX12 result of 16,408 points. That score places the NVIDIA card at the 59th percentile among all GPUs in the database, with an average benchmark score identical to that single result.

The NVIDIA RTX PRO 6000 Blackwell’s nearest rivals in the database are instructive. The AMD Radeon PRO W7500 scores 16,415, a delta of 0% relative to the RTX PRO 6000 Blackwell. The AMD Radeon RX 5700 XT scores 16,361, which is 0.3% behind. The AMD Radeon Pro 5600M scores 16,351, 0.4% behind. The NVIDIA GeForce RTX 5090 D V2 scores 16,504, putting it 0.6% ahead of the RTX PRO 6000 Blackwell. These margins are narrow, within roughly one percentage point in either direction, indicating that the RTX PRO 6000 Blackwell sits in a tightly competitive performance band in this particular DX12 workload.

Because the AMD Steam Machine GPU has no benchmark score and no nearest rivals listed, the database provides no measured comparison point for it. The wins counter shows zero wins for both parts, reflecting the absence of direct head-to-head results. The data therefore cannot establish which card is faster in any specific test; only the NVIDIA card has any recorded performance data at all.

The AMD Steam Machine GPU’s percentile versus all GPUs is 50, but with an average benchmark score of zero, that percentile reflects its position in the database hierarchy rather than any measured performance. The NVIDIA RTX PRO 6000 Blackwell’s percentile of 59, paired with an actual score, gives it a concrete standing among all recorded GPUs.

Architecture Differences

The two GPUs diverge sharply in nearly every architectural category. 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 NVIDIA RTX PRO 6000 Blackwell uses the GB202 chip on Blackwell 2.0 architecture, with no codename listed, and belongs to the Blackwell PRO W (x000) generation.

Process nodes differ. The AMD part uses a 6 nm process from TSMC, while the NVIDIA part uses a 5 nm process, also from TSMC. Transistor counts scale accordingly: the AMD chip carries 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². The NVIDIA chip carries 92,200 million transistors on a 750 mm² die, for a density of 122.9M per mm². The NVIDIA die is more than three and a half times larger in area and holds nearly seven times as many transistors, with roughly double the density.

Memory configurations are completely different. The AMD Steam Machine GPU has 8 GB of GDDR6 on a 128-bit bus, with a memory clock of 2250 MHz (18 Gbps effective) and bandwidth of 288.0 GB/s. The NVIDIA RTX PRO 6000 Blackwell has 96 GB of GDDR7 on a 512-bit bus, with a memory clock of 1750 MHz (28 Gbps effective) and bandwidth of 1.79 TB/s. The NVIDIA card offers 12 times the capacity and over six times the bandwidth.

Compute resources also scale dramatically. The AMD GPU has 1,792 shading units, 112 texture mapping units, and 64 ROPs. The NVIDIA GPU has 24,064 shading units, 752 TMUs, and 192 ROPs. Ray tracing cores number 28 on the AMD side versus 188 on the NVIDIA side. The NVIDIA card also includes 752 tensor cores; the AMD card lists none. Pixel rate on the AMD part is 156.8 GPixel/s versus 502.5 GPixel/s on the NVIDIA part. Texture rate is 274.4 GTexel/s versus 1,968.0 GTexel/s. FP32 throughput is 17.56 TFLOPS on the AMD card versus 126.0 TFLOPS on the NVIDIA card, and FP16 is identical to FP32 on both (1:1 ratio).

Clocks differ in profile. The AMD card has a base clock of 1720 MHz, a boost of 2450 MHz, and a game clock of 2250 MHz. The NVIDIA card has a base of 1590 MHz and a boost of 2617 MHz, with no game clock listed. The AMD card’s higher base clock does not compensate for the NVIDIA card’s far larger shader array.

Power and physical characteristics diverge as well. The AMD Steam Machine GPU has a TDP of 110 W and no power connectors, suggesting it draws entirely from its slot or motherboard interface, though no bus interface is listed. The NVIDIA RTX PRO 6000 Blackwell has a TDP of 600 W, requires a single 16-pin connector, and lists a suggested PSU of 1000 W. The NVIDIA card is dual-slot, 304 mm long, 137 mm high, and 40 mm wide. The AMD card is 156 mm long, 152 mm high, and 162 mm wide, with no slot width specified. Display outputs: the AMD card has 1x HDMI 2.1a and 1x DisplayPort 2.1; the NVIDIA card has 4x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release dates place them in different eras. The NVIDIA RTX PRO 6000 Blackwell launched on March 17, 2025. The AMD Steam Machine GPU is dated June 28, 2026. Both are marked as Active in production status. The NVIDIA card has a predecessor named Workstation Ada and a launch MSRP of 8,565 USD. The AMD card has no predecessor, successor, or launch MSRP listed.

The Verdict

From the recorded data, the NVIDIA RTX PRO 6000 Blackwell is the only one of the two with any measured benchmark result. Its 3DMark Steel Nomad DX12 score of 16,408 places it at the 59th percentile among all GPUs, and its nearest rivals are all within 0.6% of its score, indicating a tight cluster of performance around this level. The AMD Steam Machine GPU has no benchmark scores, no nearest rivals, and an average benchmark score of zero, so the database offers no evidence of its performance in any workload.

The AMD Steam Machine GPU’s 50th percentile position with zero measured scores suggests it occupies a middle tier in the database hierarchy by category, but no performance data supports any claim about its speed. The NVIDIA card’s 96 GB of GDDR7 memory, 1.79 TB/s bandwidth, 188 ray tracing cores, and 752 tensor cores indicate a professional workstation-class part. The AMD card’s 8 GB of GDDR6, 288.0 GB/s bandwidth, and 28 ray tracing cores indicate a far smaller, lower-power design at 110 W versus 600 W.

For users requiring verified performance in DX12 workloads, the database points clearly to the NVIDIA RTX PRO 6000 Blackwell. For users constrained by power draw, the AMD Steam Machine GPU’s 110 W TDP and lack of external power connectors represent a substantially lighter power requirement, though no measured performance confirms what that lower power buys. The data does not support a recommendation for the AMD card on performance grounds, because no performance exists in the database. The NVIDIA card’s 126.0 TFLOPS FP32, 1,968.0 GTexel/s texture rate, and 502.5 GPixel/s pixel rate are the only recorded throughput figures between the two parts.

Where Each One Wins

The NVIDIA RTX PRO 6000 Blackwell wins in every category where the database contains measurable or specifiable data. Its FP32 throughput of 126.0 TFLOPS dwarfs the AMD Steam Machine GPU’s 17.56 TFLOPS. Its texture rate of 1,968.0 GTexel/s is over seven times the AMD card’s 274.4 GTexel/s. Its pixel rate of 502.5 GPixel/s is more than three times the AMD card’s 156.8 GPixel/s. Memory bandwidth of 1.79 TB/s is more than six times the AMD card’s 288.0 GB/s. Memory capacity of 96 GB is twelve times the AMD card’s 8 GB. The NVIDIA card has 24,064 shading units versus 1,792, 752 TMUs versus 112, 192 ROPs versus 64, 188 ray tracing cores versus 28, and 752 tensor cores versus none. Its 92,200 million transistors on a 750 mm² die vastly exceed the AMD card’s 13,300 million on 204 mm². Its single recorded benchmark score of 16,408 stands alone, as the AMD card has no score.

The AMD Steam Machine GPU wins in areas of physical and electrical efficiency. Its TDP of 110 W is far lower than the NVIDIA card’s 600 W. It requires no power connectors, while the NVIDIA card requires a 16-pin connector and a 1000 W suggested PSU. The AMD card’s dimensions (156 mm length, 152 mm height, 162 mm width) are compact, particularly in length versus the NVIDIA card’s 304 mm. The AMD card’s base clock of 1720 MHz is higher than the NVIDIA card’s 1590 MHz, though its boost clock of 2450 MHz is lower than the NVIDIA card’s 2617 MHz. The AMD card’s memory clock of 2250 MHz (18 Gbps effective) is higher than the NVIDIA card’s 1750 MHz (28 Gbps effective), but the NVIDIA card’s wider 512-bit bus and GDDR7 type give it far greater total bandwidth.

The AMD Steam Machine GPU also wins on release recency, with a 2026-06-28 date versus the NVIDIA card’s 2025-03-17 date. The AMD card lists one HDMI 2.1a output and one DisplayPort 2.1 output, versus the NVIDIA card’s four DisplayPort 2.1b outputs; the NVIDIA card offers more display outputs, but the AMD card includes an HDMI option. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is a tie. The NVIDIA card has a launch MSRP of 8,565 USD, while the AMD card has no launch MSRP listed, meaning the database records no price for the AMD part.

In terms of production status, both are Active. The NVIDIA card has a predecessor (Workstation Ada) and no successor; the AMD card has neither predecessor nor successor. The NVIDIA card’s percentile versus all GPUs is 59, while the AMD card’s is 50, but the AMD card’s percentile is based on no measured scores. The practical split from the data: the NVIDIA RTX PRO 6000 Blackwell dominates all measured and specified performance metrics, while the AMD Steam Machine GPU offers lower power draw, smaller physical footprint, and a more recent release date, at the cost of having no recorded performance evidence.
