AMD Radeon 860M vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 860M and the NVIDIA N1X 48SM. The head-to-head field is empty, and neither part has an average benchmark score that can be directly contrasted: the Radeon 860M records an average benchmark score of 26,401, while the N1X 48SM currently shows no recorded benchmark scores at all.

What the data does provide is a single useful reference point. The Radeon 860M scores 22,759 in Geekbench OpenCL and 30,043 in Geekbench Vulkan. Those two results average to 26,401, which places the part at the 72nd percentile among all GPUs in the database. The N1X 48SM sits at the 50th percentile, but with an average score of zero, that percentile placement reflects the absence of measured performance rather than a competitive result.

For context on the Radeon 860M, its nearest rivals in the database are the NVIDIA GeForce MX550 with an average score of 26,421 and a delta of -0.1%, the NVIDIA GeForce RTX 5060 with 26,331 and a delta of +0.3%, the AMD Radeon RX 5700 XT 50th Anniversary with 26,553 and a delta of -0.6%, and the NVIDIA RTX A4000 with 26,683 and a delta of -1.1%. The Radeon 860M is statistically indistinguishable from these parts, trailing the RTX A4000 by 1.1%, the RX 5700 XT 50th Anniversary by 0.6%, and the MX550 by 0.1%, while leading the RTX 5060 by 0.3%. All deltas fall within a narrow band, so the 860M sits squarely in a cluster of mid-range performers.

The N1X 48SM has no nearest rivals, no benchmarks, and no wins recorded. Any comparison between the two parts must therefore rely on architectural and specification differences rather than measured performance.

Where Each One Wins

Based strictly on recorded data, the AMD Radeon 860M is the only part with measurable wins. It has a benchmark presence, a 72nd percentile placement, and an average score of 26,401. It also wins on clock speed, with a 3000 MHz boost clock versus 2346 MHz for the N1X 48SM, and on process node, using a 4 nm process against the N1X 48SM's 5 nm process. The Radeon 860M also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1X 48SM lists N/A for all three APIs.

The NVIDIA N1X 48SM wins on raw specification counts. It has 6,144 shading units versus 512, 384 texture mapping units versus 32, 48 render output units versus 16, 48 ray tracing cores versus 8, and 192 tensor cores versus none on the Radeon 860M. The N1X 48SM also delivers higher theoretical rates: 112.6 GPixel/s versus 48.00 GPixel/s, 900.9 GTexel/s versus 96.00 GTexel/s, and 28.83 TFLOPS FP32 versus 3.072 TFLOPS. Its memory subsystem is dedicated rather than shared, with 128 GB of LPDDR5X at 273.2 GB/s compared to system-dependent bandwidth for the Radeon 860M.

The N1X 48SM also has a wider bus interface, PCIe 5.0 x16 versus PCIe 4.0 x8, and a larger die at 382 mm², though the Radeon 860M's die size is unknown. The N1X 48SM includes 1x HDMI as a display output, while the Radeon 860M's outputs are portable device dependent.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Radeon 860M uses a 4 nm TSMC process; the N1X 48SM uses a 5 nm TSMC process. The N1X 48SM has a known die size of 382 mm², while the Radeon 860M's die size is unknown. Both have unknown transistor counts.

Clock speeds differ substantially. The Radeon 860M runs a 600 MHz base and 3000 MHz boost. The N1X 48SM runs a 741 MHz base and 2346 MHz boost. Memory clocks also differ: the Radeon 860M uses system shared memory with no dedicated clock, while the N1X 48SM uses 1067 MHz memory with 8.5 Gbps effective speed.

Memory capacity, type, bus width, and bandwidth all favor the N1X 48SM. It has 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth. The Radeon 860M has system shared memory, system shared type, system shared bus width, and system dependent bandwidth.

Compute unit counts show a massive disparity. The N1X 48SM has 6,144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 192 tensor cores. The Radeon 860M has 512 shading units, 32 TMUs, 16 ROPs, and 8 RT cores, with no tensor cores listed.

Theoretical throughput follows the same pattern. The N1X 48SM produces 112.6 GPixel/s, 900.9 GTexel/s, and 28.83 TFLOPS for both FP32 and FP16. The Radeon 860M produces 48.00 GPixel/s, 96.00 GTexel/s, and 3.072 TFLOPS for both FP32 and FP16.

Power and interface details also differ. The Radeon 860M has a 15 W TDP; the N1X 48SM has an unknown TDP. Both are IGP slot width with no power connectors. The Radeon 860M uses PCIe 4.0 x8; the N1X 48SM uses PCIe 5.0 x16. Display outputs are portable device dependent on the Radeon 860M and 1x HDMI on the N1X 48SM.

API support diverges sharply. The Radeon 860M lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan.

Release dates differ by over a year. The Radeon 860M released on 2025-02-28; the N1X 48SM releases on 2026-05-31.

Architecture Differences

The Radeon 860M is built on AMD's RDNA 3.5 architecture using the Krackan Point chip, part of the Navi III IGP generation for Strix Point Mobile. The N1X 48SM uses NVIDIA's Blackwell 2.0 architecture with the GB20B chip, part of the Blackwell IGP generation under the N1x family.

The process nodes differ: 4 nm for the Radeon 860M, 5 nm for the N1X 48SM, both from TSMC. The N1X 48SM includes 192 tensor cores, which the Radeon 860M lacks entirely. Ray tracing hardware also differs, with 48 RT cores on the N1X 48SM versus 8 on the Radeon 860M.

The N1X 48SM's memory architecture is a dedicated 128 GB LPDDR5X pool with 273.2 GB/s bandwidth, whereas the Radeon 860M relies on system shared memory with bandwidth dependent on the host platform. This is a fundamental architectural split: one part carries its own memory, the other borrows from the system.

The Radeon 860M has a predecessor in the Navi II IGP, while the N1X 48SM has no listed predecessor. Neither part has a successor. The Radeon 860M supports the full modern API stack, while the N1X 48SM records no API support, which suggests a platform-specific or non-standard driver environment, though the database does not elaborate on that point.

The N1X 48SM's die is 382 mm², a large integrated GPU die. The Radeon 860M's die size is unknown, but its 15 W TDP indicates a power-constrained design, while the N1X 48SM's TDP is unknown.

The Verdict

The data presents an unusual contrast. The AMD Radeon 860M is a measured, benchmarked product with a 72nd percentile standing and an average score of 26,401, placing it in a tight cluster with the GeForce MX550, RTX 5060, RX 5700 XT 50th Anniversary, and RTX A4000. The NVIDIA N1X 48SM has no benchmark results, no nearest rivals, and no recorded wins, so its 50th percentile placement is not backed by performance data.

For users who need a working, tested GPU with API support and immediate compatibility, the Radeon 860M is the only option with evidence in the database. It delivers a boost clock of 3000 MHz, a 4 nm process, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it fits within a 15 W power envelope.

For users who prioritize raw compute specifications, the N1X 48SM offers far larger numbers: 6,144 shading units, 28.83 TFLOPS, 128 GB of LPDDR5X, 192 tensor cores, and 48 RT cores. Those figures dwarf the Radeon 860M's 512 shading units, 3.072 TFLOPS, and 8 RT cores. The N1X 48SM also has a 256-bit memory bus and 273.2 GB/s bandwidth, whereas the Radeon 860M depends on system memory.

The choice depends on whether the user trusts measured results or listed specifications. The Radeon 860M has the measured results. The N1X 48SM has the specifications on paper but none of the verification. The database records no head-to-head tests, so there is no direct evidence of how the N1X 48SM's theoretical throughput translates into real performance. Given that the N1X 48SM has no API support listed and no benchmark scores, its 50th percentile rank should be treated as provisional.

The Radeon 860M is the safer selection for anyone seeking a GPU with confirmed performance and broad software compatibility. The N1X 48SM is the selection for anyone who needs maximum compute throughput and memory capacity in an integrated package, provided the missing benchmark data does not deter them. The recorded data favors the Radeon 860M for immediate use, while the N1X 48SM's appeal rests entirely on its specification sheet.
