AMD Radeon 890M vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Radeon 890M and the NVIDIA N1X 48SM. The database lists 10 benchmark scores for the AMD Radeon 890M across DX9, DX10, DX11, DX12, OpenCL, Vulkan, and compute workloads. The NVIDIA N1X 48SM has no benchmark scores recorded, so its performance profile is derived entirely from architectural specifications rather than measured results.

The AMD Radeon 890M posts an average benchmark score of 9210 across all recorded tests. Its percentile rank sits at 45 among all GPUs in the database. The nearest rivals to the 890M include the AMD Radeon Vega 8 with an average score of 9221 (0.1% behind the 890M), the NVIDIA GeForce GTX 960 at 9273 (0.7% ahead), the NVIDIA GeForce GTX 465 at 9294 (0.9% ahead), and the NVIDIA GeForce GTX 850M at 9302 (1% ahead). These deltas are narrow, indicating the 890M operates in the mid-range tier of integrated graphics performance.

Specific benchmark results for the 890M show a Geekbench Vulkan score of 40808, which is its highest recorded result, followed by a Geekbench OpenCL score of 37254. The Passmark G3D score reaches 8076, while the Passmark G2D score sits at 979. Compute performance via Passmark GPU Compute measures 4157. DirectX results are lower: Passmark DX11 scores 73, DX9 scores 97, DX12 scores 37, and DX10 scores 33. The 3DMark Steel Nomad DX12 test records 590 points.

The NVIDIA N1X 48SM, with its 28.83 TFLOPS FP32 throughput and 900.9 GTexel/s texture rate, projects substantially higher raw compute capacity than the 890M's 5.939 TFLOPS and 185.6 GTexel/s. However, without recorded benchmark scores, the database cannot quantify the actual performance gap. The N1X 48SM's percentile rank of 50 reflects its position in the database, but the lack of benchmark entries means this rank is not supported by measured results.

Architecture Differences

The AMD Radeon 890M uses the Strix Point chip built on RDNA 3.5 architecture, manufactured on TSMC's 4 nm process node. The die measures 233 mm² and contains 34,000 million transistors, yielding a transistor density of 145.9 million per square millimeter. The NVIDIA N1X 48SM uses the GB20B chip based on Blackwell 2.0 architecture, fabricated on TSMC's 5 nm process. Its die size is larger at 382 mm², but the transistor count is listed as unknown, so density cannot be calculated.

The 890M belongs to the Navi III IGP generation for Strix Point Mobile, while the N1X 48SM belongs to the Blackwell IGP generation for the N1x platform. The 890M's predecessor is Navi II IGP; the N1X 48SM has no predecessor listed. Both are active production parts with no successors recorded.

Clock behavior differs significantly. The 890M has a 400 MHz base clock and a 2900 MHz boost clock. The N1X 48SM has a 741 MHz base clock and a 2346 MHz boost clock. The 890M runs at a much higher boost frequency, but the N1X 48SM compensates with far more execution units.

The 890M integrates 1024 shading units, 64 texture mapping units, 32 ROPs, and 16 ray tracing cores. The N1X 48SM integrates 6144 shading units, 384 TMUs, 48 ROPs, 48 ray tracing cores, and 192 tensor cores. The N1X 48SM has 6 times the shading units, 6 times the TMUs, 1.5 times the ROPs, and 3 times the ray tracing cores compared to the 890M.

Memory architecture diverges sharply. The 890M uses system shared memory with a system dependent bus width and bandwidth. The N1X 48SM has dedicated 128 GB of LPDDR5X memory on a 256 bit bus, delivering 273.2 GB/s bandwidth. Memory clocks show 1067 MHz with 8.5 Gbps effective transfer for the N1X 48SM, while the 890M's memory clock is listed as system shared.

API support also differs. The 890M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1X 48SM lists N/A for DirectX, OpenGL, and Vulkan, indicating the database has not recorded API compatibility for this part.

Where Each One Wins

The AMD Radeon 890M wins in power efficiency and clock speed. Its 15 W TDP is a fully recorded figure, while the N1X 48SM's TDP is unknown. The 890M boosts to 2900 MHz, which is 554 MHz higher than the N1X 48SM's 2346 MHz boost. For thermally constrained portable devices, the 890M's lower power envelope and higher boost clock make it a practical choice. It also has complete API support including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which matters for software compatibility.

The NVIDIA N1X 48SM wins decisively on raw compute resources. Its 6144 shading units and 384 TMUs dwarf the 890M's 1024 shading units and 64 TMUs. The FP32 throughput of 28.83 TFLOPS is 4.9 times the 890M's 5.939 TFLOPS. Texture rate reaches 900.9 GTexel/s versus 185.6 GTexel/s, a 4.9 times advantage. Pixel rate is 112.6 GPixel/s versus 92.80 GPixel/s, a 21% lead. The N1X 48SM also has 192 tensor cores, which the 890M lacks entirely, making it suited for AI and machine learning workloads. Its 128 GB of LPDDR5X memory at 273.2 GB/s bandwidth is a substantial advantage over system shared memory, particularly for large datasets or high-resolution textures. The PCIe 5.0 x16 interface provides 4 times the lane width and a newer standard compared to PCIe 4.0 x8.

The 890M wins on measured benchmark presence. It has 10 recorded scores across multiple APIs and workloads, giving the database concrete data on its performance. The N1X 48SM has no benchmark entries, so its real-world performance cannot be verified from the database.

The Verdict

The data presents two very different integrated GPUs with no direct benchmark comparison. The AMD Radeon 890M is a compact, power-conscious part: 15 W TDP, 233 mm² die, 4 nm process, and a boost clock of 2900 MHz. It delivers 5.939 TFLOPS FP32 and supports a full range of APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its average benchmark score of 9210 places it at the 45th percentile, with nearest rivals within 1% in either direction. It uses system shared memory, which ties performance to the host system's RAM configuration.

The NVIDIA N1X 48SM is a larger, more powerful part: 382 mm² die, 5 nm process, 6144 shading units, 28.83 TFLOPS FP32, and 900.9 GTexel/s texture rate. It carries 192 tensor cores for AI workloads and 48 ray tracing cores for ray-traced rendering. Its 128 GB of LPDDR5X memory at 273.2 GB/s bandwidth is a massive upgrade over shared memory. The N1X 48SM uses PCIe 5.0 x16, double the lane count and a newer standard than the 890M's PCIe 4.0 x8. Its release date of 2026-05-31 is nearly two years after the 890M's 2024-07-14 launch.

For users who need confirmed, measured performance in existing software, the 890M has the advantage of recorded benchmark scores. For users who prioritize raw compute capacity, memory bandwidth, and tensor core support, the N1X 48SM is the stronger part on paper. The 890M suits power-sensitive mobile devices where 15 W is a hard constraint. The N1X 48SM suits workloads that demand high FP32 throughput, large memory pools, and AI acceleration, provided the system can accommodate its unknown power draw. The choice depends on whether verified performance or theoretical capability matters more for the target application.
