AMD Radeon 8060S vs NVIDIA GeForce RTX 4090 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive NVIDIA victory in every direct comparison available. In Geekbench OpenCL, the RTX 4090 Mobile scores 180,831 against the Radeon 8060S's 84,626, a delta of 53.2 percent in NVIDIA's favor. The Vulkan result tells a similar story: 170,774 versus 80,483, or a 52.9 percent advantage for the RTX 4090 Mobile. These are not marginal gaps; they represent more than double the AMD part's output in both compute APIs.

The RTX 4090 Mobile's average benchmark score across its full suite lands at 43,667, placing it in the 84th percentile of all GPUs in the database. The Radeon 8060S, despite winning zero head-to-head tests, posts a higher average of 55,757 across its three recorded benchmarks, which puts it in the 87th percentile. That apparent contradiction stems from the different test sets: the AMD part's average is boosted by its 3DMark Steel Nomad DX12 result of 2,162, a test the RTX 4090 Mobile has no recorded score for. The RTX 4090 Mobile's PassMark G3D score of 27,212 and its PassMark GPU Compute score of 12,347 contribute heavily to its average, but its older DirectX 9 and DirectX 10 results (310 and 173 respectively) pull the overall figure down.

When the two GPUs are placed side by side in the same workloads, the pattern is consistent. The RTX 4090 Mobile leads by roughly 53 percent in both OpenCL and Vulkan, which suggests the advantage is compute-bound rather than API-specific. The Radeon 8060S's nearest rivals in the database, the RX 6750 GRE 12 GB and RTX 5080, sit within 0.1 and 0.6 percent of its average score respectively, indicating the AMD part is competitive with those desktop-class GPUs in aggregate terms. The RTX 4090 Mobile's nearest rivals, including the Quadro M6000 and RTX A6000, cluster within 0.9 percent of its average, but those are workstation-oriented parts with different driver optimizations.

Architecture Differences

The two chips take fundamentally different design paths. The Radeon 8060S uses AMD's Strix Halo chip built on RDNA 3.5 architecture, fabricated on a 4 nm TSMC process. The RTX 4090 Mobile uses the AD103 chip on Ada Lovelace architecture, fabricated on a 5 nm TSMC process. The process node difference gives AMD a density edge: the Radeon 8060S packs an unknown transistor count into a 308 mm² die, while the RTX 4090 Mobile contains 45,900 million transistors across a 379 mm² die, yielding a density of 121.1 million transistors per square millimeter.

The compute resources diverge sharply. The RTX 4090 Mobile fields 9,728 shading units, 304 texture mapping units, and 112 ROPs, versus the Radeon 8060S's 2,560 shading units, 160 TMUs, and 64 ROPs. Ray tracing hardware also favors NVIDIA: 76 RT cores against AMD's 40, and the RTX 4090 Mobile adds 304 tensor cores, a feature category the Radeon 8060S does not specify. The raw throughput numbers reflect this scale difference. The RTX 4090 Mobile delivers 32.98 TFLOPS FP32 and FP16 (1:1), while the Radeon 8060S manages 14.85 TFLOPS in both. Pixel and texture rates follow suit: 189.8 GPixel/s and 515.3 GTexel/s for NVIDIA, versus 185.6 GPixel/s and 464.0 GTexel/s for AMD.

Memory architecture is another stark contrast. The RTX 4090 Mobile has a dedicated 16 GB GDDR6 pool on a 256-bit bus, with 576.0 GB/s of bandwidth at 18 Gbps effective. The Radeon 8060S relies entirely on system shared memory, with its size, type, bus width, and bandwidth all marked as system dependent. Clock behavior also differs: AMD's chip runs at a 1295 MHz base and 2900 MHz boost, while NVIDIA's operates at 1335 MHz base and 1695 MHz boost. The power envelopes are not comparable: the Radeon 8060S is rated at 55 W TDP, the RTX 4090 Mobile at 120 W. Both use no power connectors and are integrated into the portable device, but the AMD part is a 4 nm design with a higher boost clock and lower power draw.

The bus interface differs as well. AMD uses PCIe 5.0 x16, while NVIDIA uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. The RTX 4090 Mobile's predecessor is the GeForce 30 Mobile series, and its successor is the GeForce 50 Mobile series. The Radeon 8060S's predecessor is listed as Polaris Mobile, with no successor recorded.

Where Each One Wins

The RTX 4090 Mobile wins in raw compute throughput and dedicated memory bandwidth. Its 32.98 TFLOPS FP32 is more than double the Radeon 8060S's 14.85 TFLOPS, and its 576.0 GB/s of dedicated GDDR6 bandwidth versus system-shared memory gives it a clear advantage in memory-intensive workloads. The 76 RT cores and 304 tensor cores make it the stronger choice for ray-traced rendering and AI-accelerated tasks, assuming the software can utilize those features. The benchmark data confirms this: NVIDIA wins both head-to-head tests by over 50 percent.

The Radeon 8060S wins in efficiency and integration. Its 55 W TDP is less than half of the RTX 4090 Mobile's 120 W, and it achieves a higher boost clock at 2900 MHz versus 1695 MHz. The 4 nm process node allows for a smaller die (308 mm² versus 379 mm²) with a lower power draw, which matters in thin-and-light portable devices where thermal and battery constraints are tight. Its average benchmark score of 55,757 also exceeds the RTX 4090 Mobile's 43,667, but that is a function of different test suites rather than a direct performance claim. The Radeon 8060S's 3DMark Steel Nomad DX12 score of 2,162, which has no NVIDIA counterpart in the database, suggests it holds up in modern DX12 gaming workloads despite the compute deficit.

For gaming on a portable device with limited power delivery, the Radeon 8060S makes sense. For maximum performance in compute-heavy applications, the RTX 4090 Mobile is the clear pick. The data does not support a middle ground: one part is built for efficiency, the other for brute force.
