AMD Steam Machine GPU vs NVIDIA RTX PRO 6000 Blackwell Max-Q Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is unusually sparse. The AMD Steam Machine GPU and the NVIDIA RTX PRO 6000 Blackwell Max-Q do not share any head-to-head benchmark entries in the database. The AMD part has no benchmark scores recorded at all, with an average benchmark score of zero. The NVIDIA part has exactly one recorded result: a score of 11088 in the 3DMark Steel Nomad DX12 test. This single score places the RTX PRO 6000 Blackwell Max-Q at the 50th percentile of all GPUs in the database, a figure it shares with the AMD Steam Machine GPU, which also sits at the 50th percentile despite having no recorded measurements.

The nearest rival data for the NVIDIA part provides some context for its single benchmark score. The RTX PRO 6000D Blackwell Max-Q, a sibling product, records an identical average score of 11088, showing a delta of 0 percent. The AMD Radeon RX 550 trails marginally with a score of 11075, a delta of 0.1 percent. The NVIDIA GeForce GTX 1650 SUPER scores 11047, a delta of 0.4 percent. The AMD FirePro W4300 leads the group with a score of 11225, putting the RTX PRO 6000 Blackwell Max-Q 1.2 percent behind. These deltas are all within roughly one percentage point, indicating that in this particular DX12 test, the RTX PRO 6000 Blackwell Max-Q performs at a level comparable to several very different GPUs, though the database does not provide comparable measurements for the AMD Steam Machine GPU.

Because the head-to-head benchmark array is empty and the AMD part has no benchmark entries, the data cannot support a direct numerical comparison of the two products in any workload. The wins tally reflects this: the AMD product records zero wins and the NVIDIA product records zero wins. The only quantitative benchmark evidence available belongs exclusively to the NVIDIA card, and even that evidence is limited to a single test.

Where Each One Wins

The benchmark data does not assign any wins to either product. The AMD Steam Machine GPU has no recorded scores, so there is no evidence of it outperforming the NVIDIA part in any test. The NVIDIA RTX PRO 6000 Blackwell Max-Q has one score, but without a corresponding AMD result, that score cannot be converted into a comparative win.

What the data does show is a clear division of intended roles based on the hardware specifications. The AMD Steam Machine GPU is built around the Navi 33 chip with RDNA 3.0 architecture, a 6 nm process, 8 GB of GDDR6 memory on a 128 bit bus, and a 110 W TDP. Its display outputs are limited to one HDMI 2.1a port and one DisplayPort 2.1 port. The NVIDIA RTX PRO 6000 Blackwell Max-Q uses the GB202 chip with Blackwell 2.0 architecture, a 5 nm process, 96 GB of GDDR7 memory on a 512 bit bus, and a 300 W TDP. It provides four DisplayPort 2.1b outputs. These figures indicate that the AMD part is configured for a compact, low-power console-style device, while the NVIDIA part is configured for high-capacity professional workloads.

The compute resources reinforce this split. The AMD GPU delivers 17.56 TFLOPS of FP32 performance and 17.56 TFLOPS of FP16 performance at a 1:1 ratio. The NVIDIA GPU delivers 109.7 TFLOPS of FP32 and 109.7 TFLOPS of FP16, also at a 1:1 ratio. The NVIDIA part carries 752 tensor cores and 188 RT cores, while the AMD part lists 28 RT cores and no tensor core count. The AMD GPU has 1792 shading units, 112 texture mapping units, and 64 ROPs. The NVIDIA GPU has 24064 shading units, 752 TMUs, and 192 ROPs. In every measured compute category, the NVIDIA part has the larger allocation of resources.

Architecture Differences

The two GPUs come from different manufacturers and different architectural generations. 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 Max-Q uses the GB202 chip built on Blackwell 2.0 architecture and belongs to the Blackwell PRO W (x000) generation. The AMD part is fabricated on a 6 nm process at TSMC, while the NVIDIA part is fabricated on a 5 nm process, also at TSMC.

The transistor budgets differ substantially. The AMD chip contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million transistors per square millimeter. The NVIDIA chip contains 92,200 million transistors on a 750 mm² die, yielding a density of 122.9 million transistors per square millimeter. The NVIDIA die is roughly three and a half times larger in area and holds nearly seven times as many transistors, with a density advantage of nearly two to one.

Clock behavior also differs. 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, or 18 Gbps effective. The NVIDIA GPU has a lower base clock of 1035 MHz and a boost clock of 2280 MHz, with no game clock listed. Its memory runs at 1750 MHz, or 28 Gbps effective. The AMD part therefore operates at higher core clocks, while the NVIDIA part operates at a higher effective memory speed.

Memory architecture is one of the clearest differentiators. The AMD GPU uses 8 GB of GDDR6 on a 128 bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA GPU uses 96 GB of GDDR7 on a 512 bit bus, delivering 1.79 TB/s of bandwidth. That is a twelvefold increase in capacity and a bandwidth advantage of roughly 6.2 times. The NVIDIA part also uses a PCIe 5.0 x16 bus interface, while the AMD part lists no bus interface in the database.

The NVIDIA GPU includes 752 tensor cores, which the AMD part does not list at all. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The physical dimensions differ as well: the AMD card measures 156 mm in length, 152 mm in height, and 162 mm in width, while the NVIDIA card measures 267 mm in length, 111 mm in height, and 40 mm in width. The NVIDIA part is a dual-slot card with a single 16-pin power connector and a suggested PSU of 700 W, while the AMD part lists no slot width, no power connectors, and no suggested PSU.
