AMD Steam Machine GPU vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Steam Machine GPU shows no benchmark entries, while the NVIDIA RTX 5000 Mobile Ada Generation has a single recorded 3DMark Steel Nomad DX12 score of 3596. The AMD part also has no nearest rival entries, meaning the database contains no direct comparative scores between these two products. The NVIDIA part sits at the 21st percentile among all GPUs in the database, while the AMD part sits at the 50th percentile, but with an average benchmark score of zero, the percentile ranking for the AMD GPU reflects a lack of measured performance data rather than a measured outcome.

The NVIDIA RTX 5000 Mobile Ada Generation delivers a 3DMark Steel Nomad DX12 score of 3596. Its nearest rivals in the database are close, with the NVIDIA GeForce GT 545 at 3594, just 0.1% behind, the NVIDIA GeForce GT 735M at 3616, 0.6% ahead, the NVIDIA GeForce GTX 1050 at 3629, 0.9% ahead, and the AMD Radeon HD 6770 at 3649, 1.5% ahead. The RTX 5000 Mobile Ada Generation therefore lands at the lower end of a tightly clustered group of older desktop and mobile parts, all within a 1.5% performance band. For the AMD Steam Machine GPU, there is no equivalent benchmark data to place against this result, so any head-to-head comparison must rely entirely on architectural specifications rather than measured frame rates or scores.

The absence of benchmark data for the AMD part means the database cannot confirm whether the Steam Machine GPU would outperform or underperform the RTX 5000 Mobile Ada Generation in 3DMark Steel Nomad DX12. What the data does show is that the NVIDIA part, despite its high-end positioning, scores within 1.5% of GPUs from several generations prior, which suggests its real-world performance in this particular test is modest relative to its specification sheet.

Architecture Differences

The two GPUs come from different architectural families and different process nodes. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture with the codename Hotpink Bonefish, fabricated by TSMC on a 6 nm process. The NVIDIA RTX 5000 Mobile Ada Generation uses the AD103 chip built on Ada Lovelace architecture, also fabricated by TSMC but on a 5 nm process. The transistor counts differ substantially: the AMD chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm², while the NVIDIA chip contains 45,900 million transistors on a 379 mm² die, giving a density of 121.1 million per mm². The NVIDIA die is roughly 86% larger by area and carries more than three times the transistor count.

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. The NVIDIA GPU has a base clock of 1425 MHz and a boost clock of 2115 MHz, with no game clock listed. Despite lower clock speeds, the NVIDIA part delivers far higher peak compute figures, which points to a much wider execution architecture. The AMD GPU offers 1792 shading units, 112 texture mapping units, and 64 render output units, while the NVIDIA GPU offers 9728 shading units, 304 texture mapping units, and 112 render output units. The NVIDIA part also includes 76 ray tracing cores and 304 tensor cores, whereas the AMD part lists 28 ray tracing cores and no tensor core entry. The FP32 throughput tells the same story: the AMD GPU reaches 17.56 TFLOPS, while the NVIDIA GPU reaches 41.15 TFLOPS, both with 1:1 FP16 ratios.

Memory configurations are also distinct. The AMD GPU uses 8 GB of GDDR6 on a 128 bit bus, delivering 288.0 GB/s of bandwidth. The NVIDIA GPU uses 16 GB of GDDR6 on a 256 bit bus, delivering 576.0 GB/s of bandwidth, exactly double the AMD part in capacity and bandwidth. Both list a memory clock of 2250 MHz with 18 Gbps effective. Pixel and texture rates follow the same trend: the AMD GPU produces 156.8 GPixel/s and 274.4 GTexel/s, while the NVIDIA GPU produces 236.9 GPixel/s and 643.0 GTexel/s.

Power targets are close, with the AMD GPU rated at 110 W and the NVIDIA GPU at 120 W, and both use no external power connectors. The NVIDIA part is an integrated graphics package, listed as IGP slot width, with a PCIe 4.0 x16 bus interface, while the AMD part has no bus interface listed. Display outputs differ: the AMD Steam Machine GPU provides one HDMI 2.1a port and one DisplayPort 2.1 port, while the NVIDIA mobile part is marked as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD GPU measures 156 mm by 152 mm by 162 mm, while the NVIDIA mobile part has no listed dimensions. The AMD part is categorized under the Console GPU (Valve) generation with a release date of June 28, 2026, while the NVIDIA part belongs to the Ada-MW generation, released March 20, 2023, with predecessors and successors listed as Ampere-MW and Blackwell-MW respectively.

The Verdict

The data supports a clear split by workload and platform. The NVIDIA RTX 5000 Mobile Ada Generation offers more than twice the FP32 throughput, double the memory capacity, double the memory bandwidth, and a substantially larger execution resource pool across shading units, texture units, render outputs, ray tracing cores, and tensor cores. Its measured 3DMark Steel Nomad DX12 score of 3596 places it within 1.5% of the NVIDIA GeForce GT 545, the NVIDIA GeForce GT 735M, the NVIDIA GeForce GTX 1050, and the AMD Radeon HD 6770, which indicates that its raw rasterization performance in this benchmark is comparable to those older parts despite the architectural advantages.

The AMD Steam Machine GPU, by contrast, has no recorded benchmark scores and no nearest rival entries. Its specification sheet shows a smaller GPU in every compute category except clock speed and power draw, where it lists a higher base clock and a slightly lower TDP. The AMD part is built on a larger process node, carries fewer transistors, and offers less memory bandwidth. For users selecting strictly on measured performance, the NVIDIA part is the only one with database results. For users selecting on the basis of the AMD part's console integration, its compact dimensions, its RDNA 3.0 feature set, and its lack of external power connectors may matter more than raw throughput. The recorded data does not establish any performance equivalence between the two, and the NVIDIA GPU's benchmark result, while present, is modest relative to its own specification sheet.

It also has a higher transistor density at 121.1 million per mm² on a 5 nm process, and its 45,900 million transistor count is more than three times the AMD part's 13,300 million.

The AMD Steam Machine GPU wins on clock speed and physical integration. Its base clock of 1720 MHz and boost clock of 2450 MHz are higher than the NVIDIA part's 1425 MHz base and 2115 MHz boost, and it lists a game clock of 2250 MHz, a figure the NVIDIA part does not record. Its TDP of 110 W is lower than the NVIDIA part's 120 W. Its dimensions are recorded at 156 mm by 152 mm by 162 mm, while the NVIDIA mobile part has no dimensions listed. It provides fixed display outputs with one HDMI 2.1a port and one DisplayPort 2.1 port, whereas the NVIDIA mobile part's outputs are portable device dependent. Its die size of 204 mm² is smaller than the NVIDIA part's 379 mm², and its 6 nm process node is larger than the NVIDIA part's 5 nm node. The AMD part has no benchmark data, no nearest rivals, and no average score, so its wins are confined to specification-level advantages rather than measured outcomes.
