AMD Steam Machine GPU vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The database contains no shared benchmark results between the AMD Steam Machine GPU and the NVIDIA GeForce RTX 5080. The head-to-head benchmark array is empty, and neither product records a win in direct comparison. This absence of overlapping test data means a direct score-by-score contest cannot be constructed from recorded measurements. What the database does provide is a full benchmark profile for the RTX 5080 and a percentile ranking for both parts, which allows for an indirect assessment of their relative positions.

The RTX 5080 delivers a substantial benchmark portfolio. Its 3DMark Steel Nomad DX12 score of 8637 indicates strong modern API performance. In compute-oriented workloads, the Geekbench OpenCL result of 235901 and the Geekbench Vulkan result of 255450 show consistent output across different compute interfaces. The Passmark suite adds further detail: G3D score of 36565, GPU compute of 21789, DirectX 11 at 324, DirectX 10 at 208, DirectX 12 at 151, and DirectX 9 at 389. The G2D score of 1415 covers 2D acceleration. These numbers place the RTX 5080 at the 87th percentile among all GPUs in the database, with an average benchmark score of 56083.

The AMD Steam Machine GPU has no recorded benchmark scores. Its average benchmark score is listed as 0, and its percentile versus all GPUs is 50. The nearest rivals array for the AMD part is empty, so no comparative deltas exist for it. The RTX 5080, by contrast, has four nearest rivals with specific deltas. The AMD Radeon 8060S averages 55757, which is 0.6% behind the RTX 5080. The AMD Radeon RX 6750 GRE 12 GB averages 55698, 0.7% behind. The AMD Radeon Pro W5700X averages 54828, 2.3% behind. The AMD Radeon RX 9070 GRE averages 57367, which places it 2.2% ahead of the RTX 5080. These deltas show the RTX 5080 sits in a tight cluster, with the nearest AMD rival only 2.2% faster and the closest slower rival within 0.6%.

Because the AMD Steam Machine GPU lacks any measured scores, the data cannot show where it wins or loses in raw numbers. The percentile gap, however, is explicit: 50th percentile versus 87th percentile. That 37-point gap in the database ranking is the only direct statistical comparison available between the two products.

Where Each One Wins

The RTX 5080 wins in every category where the database records a measurable outcome. Its 87th percentile ranking against all GPUs confirms it sits well above the midpoint, while the AMD Steam Machine GPU sits exactly at the 50th percentile, meaning half of all recorded GPUs perform at or above its level. The RTX 5080 also wins on the availability of benchmark data itself: ten separate test scores exist for it, while the AMD part has none.

For the RTX 5080, the strongest recorded wins are in compute-heavy tests. The Geekbench Vulkan score of 255450 edges out the OpenCL score of 235901, indicating strong cross-platform compute performance. In the Passmark suite, the G3D score of 36565 dominates the older DirectX-specific tests, with DirectX 9 at 389, DirectX 11 at 324, DirectX 10 at 208, and DirectX 12 at 151. The DirectX 12 result being the lowest of the four Passmark API tests suggests that the newer API path does not extract the same relative performance as the legacy paths, although the absolute numbers remain far above what the AMD part could plausibly produce given its lack of scores.

The AMD Steam Machine GPU cannot claim a win in any benchmark category because the database holds no measurements for it. Its architectural specifications, however, indicate a different use profile. The 110 W power envelope and the absence of external power connectors suggest a design intended for constrained installations, while the RTX 5080 requires a 16-pin connector and a 750 W suggested power supply. Those are operational differences, not performance wins, but they define where each part fits.

Architecture Differences

The two GPUs come from different manufacturers, architectures, and process nodes. AMD uses the Navi 33 chip built on RDNA 3.0, codenamed Hotpink Bonefish, fabricated on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². NVIDIA uses the GB203 chip on Blackwell 2.0, fabricated on a 5 nm process, also at TSMC. That chip holds 45,600 million transistors on a 378 mm² die, for a density of 120.6 million per mm². The NVIDIA chip has more than three times the transistor count and nearly double the die area, with a density roughly 85% higher.

Memory configurations diverge sharply. The AMD part uses 8 GB of GDDR6 on a 128 bit bus, yielding 288.0 GB/s of bandwidth. The NVIDIA part uses 16 GB of GDDR7 on a 256 bit bus, yielding 960.0 GB/s, a 3.33x bandwidth advantage. Memory clocks also differ: AMD runs 2250 MHz with 18 Gbps effective, while NVIDIA runs 1875 MHz with 30 Gbps effective. The wider bus and faster effective speed explain the bandwidth gap.

Compute resources show a similar scaling. The AMD GPU has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. It has no tensor cores. The NVIDIA GPU has 10752 shading units, 336 TMUs, 112 ROPs, 84 ray tracing cores, and 336 tensor cores. NVIDIA's shading unit count is exactly 6x AMD's, its TMU count is 3x, and its ray tracing core count is 3x. The tensor core presence on NVIDIA and absence on AMD is a fundamental architectural difference, affecting AI-accelerated workloads.

Clock speeds tell a different story. AMD lists a base clock of 1720 MHz, a game clock of 2250 MHz, and a boost clock of 2450 MHz. NVIDIA lists a base of 2295 MHz and a boost of 2617 MHz, with no game clock specified. NVIDIA's base is 33% higher and its boost is 6.8% higher, but AMD's game clock of 2250 MHz sits close to NVIDIA's boost. The AMD part achieves its 17.56 TFLOPS FP32 and FP16 (1:1) performance from fewer units at higher clocks. The NVIDIA part reaches 56.28 TFLOPS FP32 and FP16 (1:1), a 3.2x advantage. Pixel rate is 156.8 GPixel/s for AMD versus 293.1 GPixel/s for NVIDIA, and texture rate is 274.4 GTexel/s versus 879.3 GTexel/s.

Process node and transistor density differences explain part of the performance gap. The 6 nm node with 65.2M transistors per mm² on AMD contrasts with the 5 nm node at 120.6M per mm² on NVIDIA. The higher density allows NVIDIA to pack far more logic into a similar physical footprint, though at the cost of a much larger overall die and a 360 W TDP against AMD's 110 W.

The Verdict

The data presents a clear performance hierarchy. The RTX 5080 occupies the 87th percentile with an average benchmark score of 56083, while the AMD Steam Machine GPU sits at the 50th percentile with no recorded scores. In every measurable dimension, from memory bandwidth to shading units to TFLOPS, the NVIDIA part leads by wide margins. The FP32 throughput advantage is 3.2x, the bandwidth advantage is 3.33x, and the transistor count advantage is 3.43x.

The AMD part is not without a defined role. Its 110 W power envelope, lack of external power connectors, and compact dimensions (156 mm length, 152 mm height, 162 mm width) position it for installations where space and power draw are constrained. The NVIDIA part, at 360 W with a 16-pin connector and a 750 W suggested PSU, demands a conventional desktop environment with substantial power delivery. The AMD part also releases later in the database timeline, on 2026-06-28 versus 2025-01-29 for NVIDIA.

The RTX 5080's nearest rivals show it is competitive within its own tier. It leads the AMD Radeon 8060S by 0.6%, the RX 6750 GRE 12 GB by 0.7%, and the Pro W5700X by 2.3%, while trailing the RX 9070 GRE by 2.2%. These deltas are small, indicating the RTX 5080 performs in a tightly contested band. The AMD Steam Machine GPU has no such comparisons available.

For a user prioritizing raw performance, recorded benchmarks, and AI capability via tensor cores, the RTX 5080 is the only option with data to support it. For a user needing low power draw, no external power connection, and a compact form factor, the AMD Steam Machine GPU offers those characteristics, though the database provides no scores to verify its performance level. The choice between the two depends entirely on whether the use case matches the RTX 5080's high-performance profile or the AMD part's constrained-power design.
