AMD Steam Machine GPU vs NVIDIA GeForce RTX 5080 SUPER Comparison

AMD Steam Machine GPU versus NVIDIA GeForce RTX 5080 SUPER is a comparison between a console-class part and a desktop flagship, and the database shows that the two are not competing in the same performance class. The Steam Machine GPU, based on the Navi 33 chip with RDNA 3.0 architecture, is built for a specific Valve console form factor, while the RTX 5080 SUPER is a full-size GeForce 50-series card. The recorded benchmark data, though limited, provides a clear directional signal: the RTX 5080 SUPER carries an average score of 3075 in 3DMark Steel Nomad DX12, while the Steam Machine GPU has no benchmark entries in the database, resulting in an average score of 0. The percentile placement reinforces the gap, with the RTX 5080 SUPER at the 19th percentile versus the Steam Machine GPU at the 50th percentile, a counterintuitive split explained by the lack of recorded data for the latter.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, and neither GPU records a win in the winsA or winsB fields. However, the available data allows for a meaningful comparison through the RTX 5080 SUPER's single benchmark result and its nearest rivals. The RTX 5080 SUPER scores 3075 in 3dmark_3dmark_steel_nomad_dx12. Its nearest rivals in the database are the NVIDIA Quadro P1000 with an average score of 3163, the Intel Arc Pro B60 with 3182, the NVIDIA GeForce 820A with 2983, and the NVIDIA GeForce GTX 860M with 2967. Against these, the RTX 5080 SUPER is 2.8% behind the Quadro P1000, 3.4% behind the Arc Pro B60, 3.1% ahead of the GeForce 820A, and 3.6% ahead of the GTX 860M. These deltas are small, indicating that within this specific benchmark, the RTX 5080 SUPER sits in a narrow band around 3000 points, neither dominating nor trailing its nearest peers by a wide margin.

Because the Steam Machine GPU has no benchmark scores, the head-to-head section can only report on the RTX 5080 SUPER's measured result. The lack of data for the AMD part is not a performance failure but a database gap. The RTX 5080 SUPER's score of 3075 places it just below the 3163 of the Quadro P1000 and the 3182 of the Arc Pro B60, while sitting above the 2983 of the GeForce 820A and the 2967 of the GTX 860M. The differences are within 3.6%, suggesting that in this particular DX12 test, the RTX 5080 SUPER is closely matched with several lower-tier parts, which is unexpected for a card with its specifications. The explanation lies in the benchmark's nature: Steel Nomad DX12 may not stress the RTX 5080 SUPER's full capabilities, or the driver state at the time of testing could have limited its output. Regardless, the recorded data stands as the only direct measurement available.

Where Each One Wins

Without benchmark results for the Steam Machine GPU, the wins-based analysis defaults to the RTX 5080 SUPER, which holds the only recorded score. The Steam Machine GPU cannot be declared a winner in any test because no test data exists for it. The RTX 5080 SUPER, by virtue of having a measured score, wins the comparison by default, but the margin is not quantifiable. Looking at the nearest rivals, the RTX 5080 SUPER's performance profile in Steel Nomad shows it is competitive with the Quadro P1000 and Arc Pro B60, both of which score slightly higher, and it clearly outpaces the GeForce 820A and GTX 860M by 3.1% and 3.6% respectively. This suggests that in lighter DX12 workloads, the RTX 5080 SUPER does not separate itself from much older or less capable GPUs, a finding that points to the benchmark's limitations rather than the card's.

For the Steam Machine GPU, the absence of scores means the database cannot attribute any wins. Its specifications, such as 17.56 TFLOPS FP32 and 288.0 GB/s memory bandwidth, do not translate into recorded victories. The RTX 5080 SUPER, meanwhile, shows 56.28 TFLOPS FP32 and 1.02 TB/s memory bandwidth, but the Steel Nomad result does not reflect that theoretical advantage over its nearest rivals. The practical takeaway from the data is that the RTX 5080 SUPER has a single win in the only recorded test, while the Steam Machine GPU has no recorded wins, leaving the comparison lopsided solely due to data availability.

Architecture Differences

The two GPUs differ fundamentally in architecture, process node, and feature set. The AMD Steam Machine GPU uses the Navi 33 chip built on RDNA 3.0, with a codename of Hotpink Bonefish, and is classified under the Console GPU (Valve) generation. It is manufactured by TSMC on a 6 nm process, packing 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2M per mm². The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip on Blackwell 2.0 architecture, part of the GeForce 50 generation, also made by TSMC but on a 5 nm process. It contains 45,600 million transistors across a 378 mm² die, achieving a density of 120.6M per mm². The RTX 5080 SUPER's transistor count is over three times higher, and its die is nearly double the size, reflecting a much more complex design.

Memory configurations diverge sharply. The Steam Machine GPU has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s bandwidth. The RTX 5080 SUPER has 24 GB of GDDR7 on a 256-bit bus, with 1.02 TB/s bandwidth, a 3.5-fold increase in capacity and a 3.5-fold increase in bandwidth. Clock speeds also differ: the Steam Machine GPU runs at a base of 1720 MHz, a game clock of 2250 MHz, and a boost of 2450 MHz, with memory at 2250 MHz or 18 Gbps effective. The RTX 5080 SUPER runs at a base of 2295 MHz and a boost of 2617 MHz, with memory at 2000 MHz or 32 Gbps effective. The higher boost clock on the NVIDIA part is modest, but the memory speed is nearly double in effective terms.

Compute resources show a massive gap. The Steam Machine GPU has 1792 shading units, 112 TMUs, 64 ROPs, and 28 RT cores, with no tensor cores listed. The RTX 5080 SUPER has 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. Pixel rate for the Steam Machine GPU is 156.8 GPixel/s, versus 293.1 GPixel/s for the RTX 5080 SUPER. Texture rate is 274.4 GTexel/s versus 879.3 GTexel/s. FP32 and FP16 performance are identical within each card, at 17.56 TFLOPS for the AMD part and 56.28 TFLOPS for the NVIDIA part, confirming that the RTX 5080 SUPER has more than three times the raw compute throughput. Power draw reflects this: the Steam Machine GPU is rated at 110 W TDP, while the RTX 5080 SUPER is at 415 W. The Steam Machine GPU uses no power connectors, while the RTX 5080 SUPER uses a single 16-pin connector.

The Verdict

The data indicates that the RTX 5080 SUPER is the only GPU with recorded performance, and its specifications dwarf those of the Steam Machine GPU. The RTX 5080 SUPER's 56.28 TFLOPS FP32, 24 GB GDDR7 memory, and 1.02 TB/s bandwidth place it in a different tier than the Steam Machine GPU's 17.56 TFLOPS, 8 GB GDDR6, and 288.0 GB/s. The benchmark score of 3075, while modest relative to its nearest rivals, is the only measured point, and it confirms the RTX 5080 SUPER functions as a working desktop GPU. The Steam Machine GPU, with no benchmark scores, cannot be assessed for actual performance in the database. The verdict is straightforward: the RTX 5080 SUPER is the appropriate choice for users requiring high-end desktop performance, evidenced by its compute density and memory subsystem, while the Steam Machine GPU is a console-oriented part with lower power draw and a compact form factor, suited for the Valve console platform.
