AMD Steam Machine GPU vs NVIDIA RTX 3000 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark entries for either GPU in the comparison set. Both the AMD Steam Machine GPU and the NVIDIA RTX 3000 Mobile Ada Generation have an average benchmark score of 0, and the head-to-head benchmark array is empty. Consequently, the wins counter shows zero for both parts. This means the quantitative comparison must rely entirely on the architectural and specification data in the database rather than on measured performance samples.

With no benchmark scores available, the percentile fields become the only relative ranking signal. Both GPUs sit at the 50th percentile versus all GPUs in the database. This indicates that, based on the database's existing distribution of recorded parts, neither unit is positioned above or below the other in aggregate standing. The absence of measured scores, however, should not be read as equivalent real-world performance; the specification sheets point toward meaningful differences in compute resources, memory throughput, and rendering capabilities.

Architecture Differences

The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, carrying the codename Hotpink Bonefish. It belongs to the Console GPU (Valve) generation. The NVIDIA RTX 3000 Mobile Ada Generation uses the AD106 chip on Ada Lovelace architecture and sits in the GeForce 30-series family, generation Ada-MW. Process nodes differ: AMD uses a 6 nm TSMC process, while NVIDIA uses a 5 nm TSMC process. Transistor counts favor NVIDIA at 22,900 million versus AMD's 13,300 million, yet the die sizes are close: NVIDIA's AD106 measures 188 mm² against AMD's 204 mm². Transistor density reflects this, with NVIDIA at 121.8M per mm² and AMD at 65.2M per mm².

Shader resources diverge sharply. The NVIDIA part packs 4608 shading units, 144 texture mapping units, and 48 ROPs, while the AMD part has 1792 shading units, 112 TMUs, and 64 ROPs. Ray tracing hardware also differs: NVIDIA includes 36 RT cores and 144 tensor cores, whereas AMD lists 28 RT cores and no tensor core count. The AMD GPU reaches higher clock frequencies, with a base of 1720 MHz, a game clock of 2250 MHz, and a boost of 2450 MHz. NVIDIA's base is 1395 MHz and boost is 1695 MHz, with no game clock listed.

Memory configurations share the same capacity and bus width: both have 8 GB of GDDR6 on a 128-bit interface. Bandwidth differs because of memory clock speeds. AMD runs memory at 2250 MHz with 18 Gbps effective, producing 288.0 GB/s. NVIDIA runs memory at 2000 MHz with 16 Gbps effective, producing 256.0 GB/s. That gives AMD a 32 GB/s bandwidth advantage.

Compute rates tell a mixed story. The AMD GPU delivers 17.56 TFLOPS FP32 and the same 17.56 TFLOPS FP16 (1:1 ratio). NVIDIA delivers 15.62 TFLOPS FP32 and 15.62 TFLOPS FP16 (1:1 ratio). AMD leads raw floating-point throughput by roughly 12%. Pixel and texture rates split differently. AMD achieves 156.8 GPixel/s and 274.4 GTexel/s. NVIDIA achieves 81.36 GPixel/s and 244.1 GTexel/s. The pixel rate gap is substantial, with AMD nearly doubling NVIDIA's output, while the texture rate gap is modest.

Power targets are close. The AMD part is rated at 110 W TDP, and the NVIDIA part at 115 W TDP. Both use no external power connectors. The NVIDIA GPU is designated as an IGP with a PCIe 4.0 x16 bus interface. The AMD GPU lists no bus interface and no slot width. Display outputs differ: AMD provides 1x HDMI 2.1a and 1x DisplayPort 2.1, while NVIDIA's outputs are described as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release dates differ by roughly three years: NVIDIA launched on 2023-03-20, AMD on 2026-06-28. NVIDIA has a predecessor, Ampere-MW, and a successor, Blackwell-MW, while AMD lists no predecessor or successor. Both are active production parts.

The Verdict

The data indicates a clear split between the two GPUs. The AMD Steam Machine GPU leads in raw compute throughput, pixel fill, and memory bandwidth. It delivers 17.56 TFLOPS FP32 against NVIDIA's 15.62 TFLOPS FP32, a 12% lead. Its pixel rate of 156.8 GPixel/s is nearly double NVIDIA's 81.36 GPixel/s. Memory bandwidth sits at 288.0 GB/s versus 256.0 GB/s. The AMD part also runs at higher clocks across the board, with a boost of 2450 MHz versus 1695 MHz.

The NVIDIA RTX 3000 Mobile Ada Generation counters with a far larger shader array: 4608 shading units versus 1792, more than 2.5 times as many. It also has more TMUs (144 versus 112), more RT cores (36 versus 28), and the only tensor cores in the comparison (144). Its transistor density is nearly double AMD's, at 121.8M per mm² versus 65.2M per mm². NVIDIA's ROP count is lower at 48 versus 64, which explains its lower pixel rate.

For users prioritizing raw FP32 throughput, pixel fill, and memory bandwidth, the AMD Steam Machine GPU has the stronger specification sheet. For workloads that depend on shader count, ray tracing hardware, or tensor operations, the NVIDIA part offers more dedicated resources. The absence of benchmark scores means no measured verdict can be issued; the database only supports a specification-level conclusion.
