Analysis: AMD Radeon 860M vs NVIDIA GeForce RTX 4080 SUPER
The Verdict
The data separates these two GPUs into entirely different performance classes. The NVIDIA GeForce RTX 4080 SUPER dominates every recorded benchmark, with an average benchmark score of 54,209 against 26,401 for the AMD Radeon 860M. The RTX 4080 SUPER holds an 86th percentile ranking across all GPUs in the database, while the Radeon 860M sits at the 72nd percentile. This is not a close contest; the RTX 4080 SUPER delivers roughly double the average score of the Radeon 860M.
The Radeon 860M is an integrated graphics processor (IGP) designed for portable devices, drawing just 15 W and occupying no expansion slot. The RTX 4080 SUPER is a triple-slot discrete card with a 320 W power draw and requires a 700 W power supply. The choice between them is dictated by system type: the Radeon 860M serves thin-and-light laptops where space and power are constrained, while the RTX 4080 SUPER targets high-end desktop builds with robust power delivery and chassis clearance. The data shows no scenario where the Radeon 860M outperforms the RTX 4080 SUPER in raw compute or graphics workloads.
Where Each One Wins
The RTX 4080 SUPER wins every head-to-head benchmark recorded. In Geekbench OpenCL, it scores 219,065 against 22,759 for the Radeon 860M, a delta of 89.6 percent in favor of NVIDIA. In Geekbench Vulkan, the RTX 4080 SUPER scores 260,075 versus 30,043, a delta of 88.4 percent. These are comprehensive victories across both compute APIs tested.
The Radeon 860M has no benchmark wins in the database. Its advantage is entirely architectural and physical: it integrates into a system on a chip with a 4 nm process node and consumes only 15 W, enabling fanless or low-noise operation in portable devices. The RTX 4080 SUPER, by contrast, requires active cooling and substantial power delivery.
For users with a portable device, the Radeon 860M provides a functional graphics solution with DirectX 12 Ultimate support and Vulkan 1.4 compatibility, sufficient for light gaming and general compute. For users with a desktop workstation or gaming rig, the RTX 4080 SUPER delivers orders of magnitude higher throughput, as reflected in its Passmark G3D score of 34,245 and its 52.22 TFLOPS of FP32 compute.
Architecture Differences
The two GPUs come from fundamentally different design philosophies. The AMD Radeon 860M uses the RDNA 3.5 architecture on a 4 nm TSMC process node, built around the Krackan Point chip. It belongs to the Navi III IGP generation for Strix Point Mobile systems. The NVIDIA GeForce RTX 4080 SUPER uses the Ada Lovelace architecture on a 5 nm TSMC process, with the AD103 chip. NVIDIA's process node is larger at 5 nm versus 4 nm, but the RTX 4080 SUPER deploys far more silicon: 45,900 million transistors on a 379 mm² die, with a transistor density of 121.1 million per mm². The Radeon 860M's transistor count and die size are not recorded in the database.
Compute resources differ massively. The Radeon 860M has 512 shading units, 32 texture mapping units, 16 raster operations units, and 8 ray tracing cores. The RTX 4080 SUPER has 10,240 shading units, 320 TMUs, 112 ROPs, and 80 ray tracing cores. NVIDIA also includes 320 tensor cores, which the AMD part lacks entirely. This explains the RTX 4080 SUPER's 52.22 TFLOPS FP32 performance against the Radeon 860M's 3.072 TFLOPS, a 17x gap in raw floating-point throughput.
Memory architecture is another fundamental split. The Radeon 860M uses system shared memory, with bandwidth described as system dependent and bus width shared from the host. The RTX 4080 SUPER has 16 GB of dedicated GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth. This dedicated high-speed memory is critical for the RTX 4080 SUPER's performance in bandwidth-intensive workloads like 4K gaming and rendering.
Clock behavior also differs. The Radeon 860M has a base clock of 600 MHz and a boost clock of 3,000 MHz, relying on aggressive boosting to reach its modest performance. The RTX 4080 SUPER runs at a base of 2,295 MHz and boosts to 2,550 MHz, with memory clocked at 1,438 MHz (23 Gbps effective). NVIDIA's higher sustained clocks across a much larger chip deliver the performance advantage.

Head-to-Head Benchmarks
The database contains two direct head-to-head comparisons between these GPUs, and the RTX 4080 SUPER wins both by overwhelming margins.
In Geekbench OpenCL, the RTX 4080 SUPER scores 219,065 against 22,759 for the Radeon 860M. The delta of 89.6 percent means NVIDIA's card delivers roughly 9.6 times the OpenCL performance of the AMD IGP. This gap reflects the difference in shading units (10,240 versus 512), FP32 throughput (52.22 versus 3.072 TFLOPS), and memory bandwidth (736.3 GB/s versus system-dependent shared memory).
In Geekbench Vulkan, the RTX 4080 SUPER scores 260,075 versus 30,043 for the Radeon 860M, a delta of 88.4 percent. Vulkan's low-level API exposes the hardware differences directly: the RTX 4080 SUPER's 320 texture mapping units and 112 ROPs process geometry and rasterization far faster than the Radeon 860M's 32 TMUs and 16 ROPs. The pixel rate of 285.6 GPixel/s for NVIDIA versus 48.00 GPixel/s for AMD reinforces this gap.
Beyond these two direct comparisons, the RTX 4080 SUPER shows additional benchmark results in the database. Its Passmark G3D score of 34,245, Passmark GPU Compute score of 19,822, and DirectX 11 score of 301 all indicate strong performance across legacy and modern workloads. The Radeon 860M has no corresponding Passmark entries recorded, so the comparison rests on the two Geekbench tests and the average scores.
The RTX 4080 SUPER's nearest rivals in the database are the RTX 4080 (average score 54,247, delta of 0.1 percent), the AMD Radeon Pro W5700X (54,828, 1.1 percent ahead), and the AMD Radeon RX 6750 GRE 12 GB (55,698, 2.7 percent ahead). These deltas are small, showing the RTX 4080 SUPER sits in a tightly contested performance tier. The Radeon 860M's nearest rivals are the NVIDIA GeForce MX550 (26,421, 0.1 percent ahead), the RTX 5060 (26,331, 0.3 percent behind), and the RX 5700 XT 50th Anniversary (26,553, 0.6 percent ahead). The Radeon 860M competes with low-end discrete GPUs, a completely different market segment.
