AMD Steam Machine GPU vs NVIDIA GeForce RTX 5070 Comparison

Head-to-Head Benchmarks

The recorded data shows a fundamental mismatch between these two GPUs. The AMD Steam Machine GPU has no benchmark entries in the database, while the NVIDIA GeForce RTX 5070 has a full suite of recorded scores. The RTX 5070 delivers 30.87 TFLOPS of FP32 compute, while the AMD part delivers 17.56 TFLOPS. That is a 13.31 TFLOPS gap, a 75.8% advantage for the NVIDIA card in raw shader throughput.

The texture rate tells a similar story. The RTX 5070 produces 482.3 GTexel/s, against 274.4 GTexel/s for the AMD Steam Machine GPU. The NVIDIA card is 75.8% faster in texture fill. Pixel rate is closer, but still favors NVIDIA: 201.0 GPixel/s versus 156.8 GPixel/s, a 28.2% lead.

Memory bandwidth is where the gap becomes dramatic. The RTX 5070 uses GDDR7 on a 192-bit bus, delivering 672.0 GB/s. The AMD part uses GDDR6 on a 128-bit bus, delivering 288.0 GB/s. That is a 133.3% bandwidth advantage for NVIDIA. In bandwidth-bound scenarios, the RTX 5070 has more than double the headroom.

The RTX 5070 also has more cores across every category. It has 6144 shading units against 1792, 192 TMUs against 112, 80 ROPs against 64, 48 RT cores against 28, and 192 tensor cores where the AMD part has none listed. The RT core count is 71.4% higher, which directly impacts ray-traced workloads. The tensor core presence gives the RTX 5070 dedicated hardware for AI and DLSS-type workloads, while the AMD part has no equivalent.

The recorded 3DMark Steel Nomad DX12 score for the RTX 5070 is 5077. Its Geekbench OpenCL score is 172660, and its Geekbench Vulkan score is 178923. Passmark G3D score is 29137, and Passmark GPU Compute score is 15787. The average benchmark score across all recorded tests is 40377, placing it in the 82nd percentile of all GPUs in the database. The AMD part sits at the 50th percentile with an average benchmark score of 0, indicating no recorded results.

Comparing the RTX 5070 to its nearest rivals in the database, it sits within a narrow band. It is 0.1% ahead of the AMD Radeon Pro 580 (40318 average), 0.8% ahead of the AMD Radeon Pro WX 7100 (40063), and 2% ahead of the NVIDIA RTX A500 Mobile (39568). It trails the AMD Radeon Pro 5300 by 1.2% (40870 average). These deltas are all within 2%, meaning the RTX 5070's average score is very close to a cluster of workstation-class GPUs.

The Verdict

The data points to one clear conclusion: the NVIDIA GeForce RTX 5070 is the substantially faster GPU in every measurable category. The AMD Steam Machine GPU has no recorded benchmark scores, while the RTX 5070 has comprehensive results across 3DMark, Geekbench, and Passmark suites. The RTX 5070 also holds a massive hardware advantage in compute units, memory bandwidth, and feature support.

Who should pick the AMD Steam Machine GPU? The data shows it is a 110 W part with no power connectors, a 6 nm process, and compact dimensions of 156 mm by 152 mm by 162 mm. It is designed for a specific console form factor. The RTX 5070, by contrast, is a 250 W dual-slot card requiring a 16-pin connector and a 600 W suggested PSU, measuring 245 mm by 115 mm by 40 mm. The AMD part fits where the NVIDIA card physically cannot.

Who should pick the RTX 5070? Anyone who needs the recorded performance. It has a 75.8% FP32 advantage, a 75.8% texture rate advantage, a 28.2% pixel rate advantage, and a 133.3% memory bandwidth advantage. It also adds 192 tensor cores, 48 RT cores, and 12 GB of GDDR7 memory. The AMD part has 8 GB of GDDR6. For gaming, compute, or ray tracing, the data unambiguously favors the RTX 5070.

Architecture Differences

The two GPUs come from different architectural generations. The AMD Steam Machine GPU uses RDNA 3.0, with the Navi 33 chip and the codename "Hotpink Bonefish". It is built on TSMC's 6 nm process with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². The RTX 5070 uses Blackwell 2.0, with the GB205 chip, built on TSMC's 5 nm process with 31,100 million transistors on a 263 mm² die, giving a transistor density of 118.3 million per mm². The NVIDIA chip has 2.34 times the transistor count on a die that is only 28.9% larger.

Clock behavior differs as well. The AMD part has a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2450 MHz. The RTX 5070 has a base clock of 2325 MHz and a boost clock of 2512 MHz, with no separate game clock listed. The NVIDIA card runs higher at the base, but the boost clocks are close. The AMD card's memory runs at 2250 MHz with 18 Gbps effective, while the RTX 5070 memory runs at 1750 MHz with 28 Gbps effective. The lower memory clock on the RTX 5070 is offset by GDDR7 and a wider 192-bit bus.

Feature sets also differ. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5070 adds 192 tensor cores, which the AMD part does not list. The RTX 5070 also has 48 RT cores versus 28, and it uses a PCIe 5.0 x16 bus interface. The AMD part has no bus interface listed. Display outputs differ: the AMD card has 1x HDMI 2.1a and 1x DisplayPort 2.1, while the RTX 5070 has 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Power delivery is a major architectural split. The AMD Steam Machine GPU is rated at 110 W TDP with no power connectors. The RTX 5070 is rated at 250 W TDP with a single 16-pin connector and a 600 W suggested PSU. The AMD part is clearly designed for a fixed console power envelope, while the RTX 5070 expects a full desktop power supply.

Where Each One Wins

The RTX 5070 wins in every recorded benchmark category. Its 3DMark Steel Nomad DX12 score of 5077, Geekbench OpenCL score of 172660, and Geekbench Vulkan score of 178923 all stand without an AMD counterpart. In Passmark, it records 29137 in G3D and 15787 in GPU Compute. The AMD part has no recorded scores to contest any of these.

In raw compute, the RTX 5070's 30.87 TFLOPS FP32 and 30.87 TFLOPS FP16 (1:1) dwarf the AMD part's 17.56 TFLOPS in both. In texture work, the RTX 5070's 482.3 GTexel/s versus 274.4 GTexel/s gives it a clear edge. In pixel output, 201.0 GPixel/s versus 156.8 GPixel/s favors NVIDIA as well.

The AMD Steam Machine GPU wins where the numbers are not about performance. It uses 110 W versus 250 W, needs no power connector, and has a smaller footprint at 156 mm by 152 mm by 162 mm versus 245 mm by 115 mm by 40 mm. It also uses 8 GB of memory instead of 12 GB, which lowers the memory footprint. Its 6 nm process and 204 mm² die are smaller than the RTX 5070's 5 nm process and 263 mm² die. For a fixed console enclosure with a hard power budget, the AMD part is the only one of the two that fits the constraints. For any workload where the recorded scores matter, the RTX 5070 is the clear winner.
