AMD Steam Machine GPU vs NVIDIA GeForce RTX 5070 SUPER Comparison

The AMD Steam Machine GPU and NVIDIA GeForce RTX 5070 SUPER represent two fundamentally different approaches to graphics hardware, one designed for a specific console platform and the other for the general desktop market. The recorded data shows a clear disparity in raw compute capability, memory configuration, and performance positioning, though each part occupies a distinct niche within the database.

Head-to-Head Benchmarks

The database contains a single benchmark result for the NVIDIA GeForce RTX 5070 SUPER, while the AMD Steam Machine GPU has no recorded benchmark scores. The RTX 5070 SUPER achieves a score of 2690 in the 3DMark Steel Nomad DX12 test, which places it at the 18th percentile of all GPUs in the database. This percentile positioning indicates that a substantial majority of recorded graphics cards outperform it in this specific workload, a notable finding given its specifications.

The nearest rivals to the RTX 5070 SUPER illustrate its competitive positioning. The NVIDIA Quadro K1100M scores 2664, a delta of 1 percent behind. The NVIDIA GeForce GT 1030 and Intel Arc Pro B50 each score 2662, both trailing by 1.1 percent. The NVIDIA GeForce GT 440 scores 2645, sitting 1.7 percent behind. These margins are exceptionally narrow, with the RTX 5070 SUPER leading its closest competitor by just 26 points. The data shows a tightly clustered group of results, indicating that in this particular benchmark, the RTX 5070 SUPER delivers performance only marginally ahead of much older and less capable hardware.

The AMD Steam Machine GPU has no benchmark entries, no average score, and no rival comparisons in the database. Its percentile ranking of 50 places it at the median of all recorded GPUs, though this figure is not derived from any measured benchmark results. The absence of head-to-head benchmark data means direct performance comparisons between the two cards cannot be quantified from the available measurements.

Where Each One Wins

The NVIDIA GeForce RTX 5070 SUPER demonstrates clear advantages in several measurable categories. Its FP32 compute reaches 32.15 TFLOPS, which is 83 percent higher than the 17.56 TFLOPS of the AMD Steam Machine GPU. The texture fill rate of 502.4 GTexel/s exceeds the AMD part by 83 percent, and the pixel rate of 201.0 GPixel/s surpasses the 156.8 GPixel/s of the AMD chip by 28 percent. These figures indicate substantially higher throughput in compute-heavy and texture-bound workloads.

Memory capacity and bandwidth heavily favor the NVIDIA card. The RTX 5070 SUPER carries 18 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The AMD Steam Machine GPU offers 8 GB of GDDR6 on a 128-bit bus, providing 288.0 GB/s. The NVIDIA card provides 125 percent more memory capacity and 133 percent more bandwidth, which directly impacts performance in high-resolution textures, large datasets, and memory-intensive scenes.

The AMD Steam Machine GPU holds advantages in power efficiency and physical footprint. Its 110 W TDP compares to 275 W for the NVIDIA card, meaning the AMD part draws 60 percent less power. The AMD card also requires no power connectors, while the RTX 5070 SUPER uses a 16-pin connector. The AMD Steam Machine GPU measures 156 mm in length, 152 mm in height, and 162 mm in width, while the RTX 5070 SUPER measures 245 mm in length, 115 mm in height, and 40 mm in width. The AMD card occupies a more compact volume, which suits its console-oriented design.

Architecture Differences

The two GPUs come from different architectural generations and manufacturing processes. The AMD Steam Machine GPU uses the Navi 33 chip based on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It is built on a 6 nm process at TSMC. The RTX 5070 SUPER uses the GB205 chip based on Blackwell 2.0 architecture, manufactured on a 5 nm process, also at TSMC. The smaller process node contributes to the NVIDIA chip's higher transistor density of 118.3M per mm², compared to 65.2M per mm² for the AMD chip.

Transistor counts differ significantly. The AMD Navi 33 contains 13,300 million transistors on a 204 mm² die. The NVIDIA GB205 contains 31,100 million transistors on a 263 mm² die. The NVIDIA chip packs 134 percent more transistors into a die that is only 29 percent larger, a direct result of the denser manufacturing process and the architectural complexity of the Blackwell design.

The compute configurations reveal different design philosophies. The AMD GPU features 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The NVIDIA GPU features 6400 shading units, 200 TMUs, 80 ROPs, 50 ray tracing cores, and 200 tensor cores. The AMD card has no tensor cores listed, while the tensor core count on the NVIDIA card suggests a focus on AI-accelerated workloads. The NVIDIA card provides 257 percent more shading units and 79 percent more TMUs, which explains its substantial lead in raw throughput metrics.

Clock speeds also differ. 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 with 18 Gbps effective speed. The NVIDIA GPU has a base clock of 2325 MHz and a boost clock of 2512 MHz, with memory at 1750 MHz and 28 Gbps effective speed. Despite the higher base clock on the NVIDIA card, the boost clocks are relatively close, with the NVIDIA part leading by just 62 MHz.

Memory technology differs by generation. The AMD card uses GDDR6, while the NVIDIA card uses GDDR7. The bus widths of 128-bit and 192-bit respectively, combined with the faster GDDR7 signaling, produce the large bandwidth gap described earlier. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical.

Display outputs show minor differences. The AMD card offers 1x HDMI 2.1a and 1x DisplayPort 2.1. The NVIDIA card offers 1x HDMI 2.1b and 3x DisplayPort 2.1b. The NVIDIA card supports more simultaneous displays through its additional DisplayPort outputs. The RTX 5070 SUPER uses a PCIe 5.0 x16 bus interface, while the AMD card has no bus interface listed in the database. The NVIDIA card is dual-slot, while the AMD card has no slot width specified.

The Verdict

The recorded data presents a one-sided technical comparison. The NVIDIA GeForce RTX 5070 SUPER outperforms the AMD Steam Machine GPU in every measured compute and memory metric, with FP32 throughput 83 percent higher, texture rate 83 percent higher, pixel rate 28 percent higher, memory bandwidth 133 percent higher, and memory capacity 125 percent higher. The NVIDIA card also carries significantly more shading units, ray tracing cores, and the only tensor cores in the comparison.

The AMD Steam Machine GPU counters with a 60 percent lower power draw, a smaller physical footprint, and no external power requirement. The 110 W TDP and connector-free design make it suitable for compact, power-constrained environments, which aligns with its console GPU generation classification. The 6 nm process and 13,300 million transistors also indicate a more modest silicon budget.

The benchmark data complicates the NVIDIA card's positioning. Despite its specification advantage, the RTX 5070 SUPER scores at the 18th percentile in the database and sits only 1 to 1.7 percent ahead of cards like the GT 1030 and GT 440 in the 3DMark Steel Nomad DX12 test. The AMD card has no benchmark results, so its real-world performance cannot be verified from the database. The percentile ranking of 50 for the AMD card is not derived from measured scores, making it an unreliable indicator.

For users prioritizing raw performance, memory capacity, and bandwidth, the RTX 5070 SUPER is the clear choice based on specifications alone. For users prioritizing power efficiency, compact dimensions, and minimal power delivery requirements, the AMD Steam Machine GPU offers a more constrained but lower-consumption alternative. The absence of head-to-head benchmark data means the verdict rests on architectural and specification differences rather than measured performance comparisons.
