Architecture Differences

The Radeon 760M and the Steam Machine GPU share the same RDNA 3.0 microarchitecture but diverge significantly in implementation. The Radeon 760M is built on the Phoenix chip using TSMC's 4 nm process, packing 25,390 million transistors into a 178 mm² die. This results in a transistor density of 142.6M per mm². In contrast, the Steam Machine GPU uses the Navi 33 chip fabricated on TSMC's 6 nm node, with 13,300 million transistors spread across a larger 204 mm² die, yielding a density of 65.2M per mm². The smaller process node allows the Radeon 760M to achieve higher transistor density despite having fewer total transistors.

The compute configuration differs substantially. The Radeon 760M features 512 shading units, 32 texture mapping units, 16 ROPs, and 8 ray tracing cores. The Steam Machine GPU scales this up to 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. That represents 3.5 times more shading units, 3.5 times more TMUs, 4 times more ROPs, and 3.5 times more ray tracing cores.

Clock behavior also distinguishes the two. The Radeon 760M has a base clock of 800 MHz and a boost clock of 2599 MHz, with no specified game clock. The Steam Machine GPU runs at a higher base of 1720 MHz, a boost of 2450 MHz, and includes a game clock of 2250 MHz. Memory architecture is radically different: the Radeon 760M relies on System Shared memory with no dedicated VRAM, while the Steam Machine GPU uses 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Radeon 760M connects via PCIe 4.0 x8 and has motherboard-dependent display outputs, while the Steam Machine GPU lists 1x HDMI 2.1a and 1x DisplayPort 2.1 outputs. The Steam Machine GPU is physically compact at 156 mm by 152 mm by 162 mm.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark comparisons between the Radeon 760M and the Steam Machine GPU. However, the Radeon 760M has an extensive set of recorded scores, while the Steam Machine GPU currently has no benchmark entries and an average benchmark score of zero.

For the Radeon 760M, the measured results show a 3DMark Steel Nomad DX12 score of 400, Geekbench OpenCL score of 20,255, and Geekbench Vulkan score of 30,336. PassMark results include 19 for DirectX 10, 52 for DirectX 11, 25 for DirectX 12, and 65 for DirectX 9. The GPU achieves 890 in PassMark G2D, 5,310 in PassMark G3D, and 2,840 in PassMark GPU Compute. Its average benchmark score across all tests is 6,019.

The Radeon 760M sits at the 35th percentile of all GPUs in the database. Its nearest rivals provide context for this positioning. The AMD Radeon RX 6400 scores 6,001, a delta of 0.3% relative to the 760M. The NVIDIA GeForce GTX 770M scores 6,000, also 0.3% higher. The NVIDIA RTX PRO 6000 Blackwell Server scores 5,996, which is 0.4% higher. The NVIDIA Quadro P2000 scores 6,049, putting it 0.5% ahead.

The Steam Machine GPU is recorded at the 50th percentile of all GPUs, but with no benchmark scores, its percentile ranking must be interpreted cautiously. The absence of recorded measurements means no quantified comparison can be made between the two GPUs based on the database's benchmark data alone.

What the data does show is that the Radeon 760M, despite being an integrated solution, lands within a narrow performance band around the 6,000 average score mark. Its closest rivals are all discrete GPUs from both AMD and NVIDIA, and the deltas are small, ranging from -0.5% to +0.4%. This indicates that the 760M performs competitively with those particular discrete cards based on average scores.

Specification Differences

The two GPUs differ across nearly every major specification category. The Radeon 760M uses the Phoenix chip, while the Steam Machine GPU uses Navi 33 with the codename "Hotpink Bonefish." Process nodes differ: 4 nm for the Radeon 760M versus 6 nm for the Steam Machine GPU. Transistor counts are 25,390 million versus 13,300 million, with die sizes of 178 mm² versus 204 mm². Transistor densities are 142.6M per mm² for the Radeon 760M and 65.2M per mm² for the Steam Machine GPU.

Clock speeds show a mixed picture. The Radeon 760M has a lower base clock (800 MHz versus 1720 MHz) but a higher boost clock (2599 MHz versus 2450 MHz). The Steam Machine GPU specifies a game clock of 2250 MHz, which the Radeon 760M lacks. Memory configurations are entirely different: the Radeon 760M uses System Shared memory with no dedicated size, type, or bus width, while the Steam Machine GPU has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth and a 2250 MHz memory clock at 18 Gbps effective.

Compute resources differ by a factor of 3.5 in shading units (512 versus 1792), TMUs (32 versus 112), and ray tracing cores (8 versus 28). ROPs differ by a factor of 4 (16 versus 64). Pixel rates are 41.58 GPixel/s versus 156.8 GPixel/s, and texture rates are 83.17 GTexel/s versus 274.4 GTexel/s. FP32 and FP16 performance are both 5.323 TFLOPS for the Radeon 760M and 17.56 TFLOPS for the Steam Machine GPU, with both maintaining a 1:1 ratio.

TDP ratings are 15 W for the Radeon 760M and 110 W for the Steam Machine GPU. The Radeon 760M is an IGP with no slot width, while the Steam Machine GPU has physical dimensions of 156 mm by 152 mm by 162 mm. The Radeon 760M uses a PCIe 4.0 x8 interface, while the Steam Machine GPU has no recorded bus interface. Display outputs are motherboard dependent for the Radeon 760M, whereas the Steam Machine GPU lists 1x HDMI 2.1a and 1x DisplayPort 2.1. Release dates are January 30, 2024, for the Radeon 760M and June 28, 2026, for the Steam Machine GPU. The Radeon 760M's predecessor is Navi II IGP; the Steam Machine GPU has no recorded predecessor or successor.

The Verdict

The recorded data shows two GPUs from the same architectural family aimed at entirely different use cases. The Radeon 760M is an integrated processor with a 15 W TDP, System Shared memory, and a 4 nm process. The Steam Machine GPU is a discrete console component with 8 GB of GDDR6, a 110 W TDP, and a 6 nm process.

From a performance standpoint, the Steam Machine GPU holds clear advantages in every compute metric recorded. Its 17.56 TFLOPS of FP32 performance, 156.8 GPixel/s pixel rate, and 274.4 GTexel/s texture rate place it well above the Radeon 760M's 5.323 TFLOPS, 41.58 GPixel/s, and 83.17 GTexel/s. The Steam Machine GPU also has 3.5 times the shading units and 4 times the ROPs.

However, the benchmark database currently contains no scores for the Steam Machine GPU, while the Radeon 760M has a full set of measurements. The Radeon 760M's average benchmark score of 6,019 and 35th percentile ranking position it near the AMD Radeon RX 6400, NVIDIA GeForce GTX 770M, and NVIDIA Quadro P2000. Its closest rival, the NVIDIA Quadro P2000, is 0.5% ahead, while the AMD Radeon RX 6400 trails by 0.3%.

The Steam Machine GPU's 50th percentile ranking, despite having no recorded benchmarks, suggests it is categorized higher in the database hierarchy. But without measured scores, a direct numeric comparison cannot be made.

For users needing a low-power integrated solution, the Radeon 760M's 15 W TDP and System Shared memory make it suitable for compact systems where dedicated graphics are not possible. For a console-class GPU with dedicated memory and substantially higher throughput, the Steam Machine GPU's specifications indicate it delivers roughly 3.3 times the FP32 compute and 3.8 times the pixel throughput of the Radeon 760M.

The choice between the two depends on the platform. The Radeon 760M is an IGP with no power connectors and motherboard-dependent outputs, designed for integration into a processor package. The Steam Machine GPU is a standalone component with fixed dimensions and dedicated display outputs. The data supports the Steam Machine GPU as the higher-performing part on paper, while the Radeon 760M offers the efficiency and integration advantages of a 4 nm IGP.
