AMD Steam Machine GPU vs NVIDIA GeForce RTX 5070 Ti Comparison

Where Each One Wins

The recorded data presents a starkly one-sided comparison. The AMD Steam Machine GPU has no benchmark entries in the database, while the NVIDIA GeForce RTX 5070 Ti has ten recorded scores across DirectX, OpenCL, and Vulkan workloads. Consequently, the win count is zero for AMD and ten for NVIDIA across all tested categories. The Steam Machine GPU's percentile rank of 50 places it at the median of all GPUs in the database, whereas the RTX 5070 Ti sits at the 86th percentile, indicating that the NVIDIA part outperforms roughly 86 percent of all tracked graphics cards. This percentile gap alone suggests a fundamental performance chasm, but the absence of AMD benchmark data prevents a direct numerical delta between the two.

For the RTX 5070 Ti, the database shows its strongest absolute scores in synthetic compute and Vulkan workloads. The Geekbench Vulkan result of 225,122 and OpenCL result of 212,363 are the two highest individual scores recorded for this card, indicating exceptional throughput in API-agnostic compute tasks. The Passmark G3D score of 32,974 and GPU compute score of 20,203 further reinforce its dominance in general-purpose rendering and compute scenarios. The Passmark DirectX 9 score of 351 and DirectX 11 score of 300 are comparatively modest, yet they still represent the only available data points for legacy API performance. The RTX 5070 Ti also records a 3DMark Steel Nomad DX12 score of 6,604, which serves as a modern DirectX 12 gaming workload metric.

The AMD Steam Machine GPU, by contrast, has no recorded scores in any test category. Its 50th percentile ranking is derived from the database's overall distribution, but without specific benchmark entries, the data cannot quantify its performance against the RTX 5070 Ti or any other rival. The wins, therefore, belong entirely to NVIDIA in every measurable dimension available in the database.

Architecture Differences

The two GPUs diverge fundamentally at the silicon level. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish, manufactured on a 6 nm TSMC process. It integrates 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The RTX 5070 Ti uses the GB203 chip on Blackwell 2.0 architecture, fabricated on a 5 nm TSMC process, containing 45,600 million transistors across a 378 mm² die, with a density of 120.6 million per square millimeter. The transistor count difference is substantial: NVIDIA's chip packs roughly 3.4 times more transistors, and its density is nearly double AMD's.

The compute resources differ accordingly. The Steam Machine GPU has 1,792 shading units, 112 texture mapping units, 64 raster operation units, and 28 ray tracing cores. The RTX 5070 Ti has 8,960 shading units (five times more), 280 TMUs (2.5 times more), 96 ROPs (1.5 times more), 70 ray tracing cores, and 280 tensor cores. The tensor core count is exclusive to NVIDIA, as the AMD part lists no tensor cores at all. This indicates a hardware divergence in AI-accelerated workloads, with the RTX 5070 Ti explicitly supporting tensor operations while the Steam Machine GPU does not.

Clock behavior also differs. The Steam Machine GPU has a base clock of 1720 MHz, a boost clock of 2450 MHz, and a game clock of 2250 MHz. The RTX 5070 Ti has a base clock of 2295 MHz and a boost clock of 2452 MHz, but no game clock is recorded. Memory clocks show 2250 MHz (18 Gbps effective) for AMD and 1750 MHz (28 Gbps effective) for NVIDIA, reflecting the different memory technologies used.

The power and physical profiles are markedly different. The Steam Machine GPU has a TDP of 110 W, no power connectors, and dimensions of 156 mm length, 152 mm height, and 162 mm width. The RTX 5070 Ti has a TDP of 300 W, a single 16-pin power connector, a suggested PSU of 700 W, a dual-slot width, and dimensions of 304 mm length, 137 mm height, and 48 mm width. The AMD part is roughly half the length and consumes less than half the power, while the NVIDIA card is a larger, more power-hungry design. The bus interface for the RTX 5070 Ti is PCIe 5.0 x16, while the Steam Machine GPU has no recorded bus interface. Display outputs also differ: AMD lists one HDMI 2.1a and one DisplayPort 2.1, while NVIDIA lists one HDMI 2.1b and three DisplayPort 2.1b ports.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are impossible because the database contains no benchmark entries for the AMD Steam Machine GPU. The head-to-head benchmark array is empty, and the win counts are zero for both sides. The RTX 5070 Ti's recorded scores stand alone, with no AMD counterpart to compare against.

The RTX 5070 Ti's nearest rivals in the database provide context for its performance level. Its average benchmark score is 49,957. The AMD Radeon RX Vega 64 scores 50,001, a delta of -0.1 percent relative to the RTX 5070 Ti, meaning the Vega 64 is essentially tied with it. The Intel Arc A550M scores 49,737, a delta of 0.4 percent, placing it slightly below. The AMD Radeon RX 6900 XT scores 50,951, a delta of -2 percent, meaning the RTX 5070 Ti trails that card by 2 percent. The AMD Radeon RX 6800 XT scores 48,477, a delta of 3.1 percent, meaning the RTX 5070 Ti leads it by 3.1 percent. These deltas show that the RTX 5070 Ti sits within a narrow performance band around 50,000 average score, with its closest rivals being previous-generation AMD flagships and a mid-range Intel mobile part.

Within its own benchmark suite, the RTX 5070 Ti shows a wide spread between workload types. The Geekbench Vulkan score of 225,122 is the highest, followed by OpenCL at 212,363. These are compute-oriented tests that often scale with raw shader throughput and memory bandwidth. The Passmark G3D score of 32,974 is the highest among Passmark tests, while the GPU compute score of 20,203 is roughly 61 percent of the G3D score. The legacy DirectX tests are much lower: DirectX 9 at 351, DirectX 11 at 300, and DirectX 12 at 127. The DirectX 10 score of 192 and the G2D score of 1,332 round out the suite. The low DirectX 12 Passmark score relative to G3D suggests that this particular test may not be representative of the card's capabilities in modern workloads.

The Verdict

The data in the database directs a clear choice toward the NVIDIA GeForce RTX 5070 Ti for any workload that requires measurable performance. The RTX 5070 Ti holds ten benchmark scores across diverse test categories, while the AMD Steam Machine GPU holds none. The percentile ranking reinforces this: the RTX 5070 Ti sits at the 86th percentile of all GPUs, while the AMD part sits at the 50th. This means the RTX 5070 Ti outperforms roughly 36 percent more of the database's tracked GPUs.

The architectural gap is equally decisive. The RTX 5070 Ti has 5 times more shading units, 2.5 times more TMUs, 2.5 times more ray tracing cores, and nearly 2.5 times the FP32 compute throughput at 43.94 TFLOPS versus 17.56 TFLOPS. Its memory bandwidth of 896.0 GB/s is over 3 times that of the AMD part's 288.0 GB/s, and its 16 GB GDDR7 capacity doubles the AMD's 8 GB GDDR6. The tensor cores present only on the NVIDIA side further separate the two for AI-accelerated tasks.

The AMD Steam Machine GPU does offer advantages in power and physical footprint. Its 110 W TDP is less than half the RTX 5070 Ti's 300 W, and its 156 mm length is about half the NVIDIA card's 304 mm. It requires no power connectors, whereas the RTX 5070 Ti needs a 16-pin connector and a 700 W suggested PSU. These traits make the AMD part suitable for compact, low-power systems, but the database provides no performance data to justify that trade-off.

For users prioritizing raw performance, modern API support, and compute throughput, the RTX 5070 Ti is the only choice supported by recorded measurements. For users constrained by power and space, the Steam Machine GPU presents a viable low-power option, but its performance remains unquantified in the database. The verdict from the data is unambiguous: the RTX 5070 Ti delivers measurable, benchmarked performance at the 86th percentile, while the AMD Steam Machine GPU offers only an unverified 50th percentile ranking.
