Intel Arc Graphics 128EU Mobile vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded data contains no direct benchmark scores for either Intel Arc Graphics 128EU Mobile or NVIDIA N1X 40SM. Both entries show an average benchmark score of 0 and an empty head-to-head benchmark array. The wins counter for each product is also zero. This means the database currently holds no measured performance results for either GPU, and no direct comparison data exists between them.

What the database does provide are the theoretical compute specifications for each part, which allow for a raw capability comparison. The Intel Arc Graphics 128EU Mobile delivers a peak FP32 throughput of 4.608 TFLOPS, while the NVIDIA N1X 40SM reaches 24.02 TFLOPS in FP32. That is a 5.2x difference in raw single-precision compute, with the NVIDIA part holding a clear mathematical advantage. In FP16, the Intel GPU achieves 9.216 TFLOPS using a 2:1 ratio, while the NVIDIA GPU sustains 24.02 TFLOPS with a 1:1 ratio. The NVIDIA part again leads, though the Intel GPU doubles its FP32 rate when moving to FP16, whereas the NVIDIA GPU does not scale.

Texture and pixel throughput also favor the NVIDIA N1X 40SM. The Intel GPU reaches a texture rate of 144.0 GTexel/s and a pixel rate of 72.00 GPixel/s. The NVIDIA part posts 750.7 GTexel/s and 93.84 GPixel/s, respectively. The texture rate difference is especially pronounced at roughly 5.2x, while the pixel rate gap is narrower at about 1.3x. These numbers reflect the underlying hardware configuration: the Intel GPU has 1024 shading units, 64 texture mapping units, and 32 ROPs, while the NVIDIA GPU has 5120 shading units, 320 TMUs, and 40 ROPs.

Clock behavior differs between the two parts. The Intel GPU has a base clock of 300 MHz and a boost clock of 2250 MHz. The NVIDIA GPU starts at 741 MHz base and boosts to 2346 MHz. Despite the lower base clock, the Intel GPU's boost clock is only about 4% lower than the NVIDIA part's boost. The NVIDIA advantage comes primarily from having 5x the shading units, not from a higher clock ceiling.

Memory bandwidth is another area of separation. The Intel GPU uses system-shared memory with a bandwidth listed as system dependent, meaning the available bandwidth is tied to whatever platform memory is installed. The NVIDIA N1X 40SM has a dedicated 128 GB LPDDR5X memory pool on a 256-bit bus, delivering 273.2 GB/s of bandwidth. The memory clock is listed at 1067 MHz with an effective data rate of 8.5 Gbps. This dedicated memory configuration removes platform dependence and provides a fixed bandwidth figure, though the two cannot be directly compared since the Intel GPU's bandwidth is not a fixed number.

The Verdict

Based strictly on the recorded specifications, the NVIDIA N1X 40SM is the higher-performance part across every measured compute metric. Its FP32 throughput of 24.02 TFLOPS is roughly 5.2x the Intel Arc Graphics 128EU Mobile's 4.608 TFLOPS. The texture rate advantage is similar at 5.2x, and the pixel rate is 1.3x higher. The NVIDIA part also carries dedicated memory with 273.2 GB/s bandwidth, while the Intel GPU relies on system-shared memory with variable bandwidth.

The Intel Arc Graphics 128EU Mobile does hold some structural advantages. Its boost clock of 2250 MHz is close to the NVIDIA part's 2346 MHz, and it supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists DirectX, OpenGL, and Vulkan as N/A in the database, which means its API support is either not yet disclosed or not applicable for its IGP classification. The Intel part also has a 28 W TDP, while the NVIDIA TDP is listed as unknown, so no power comparison is possible.

The production status for both is Active. The Intel GPU was released on 2023-12-13, and the NVIDIA part has a release date of 2026-05-31. Neither product has a launch MSRP in the database, so no price comparison exists. Both share the same percentile rank of 50 against all GPUs, though this is based on an average benchmark score of 0 for each, meaning the percentile is not yet meaningful.

For users who need raw compute throughput, the NVIDIA N1X 40SM is the clear choice based on the numbers. For users who need established API support and a fixed power envelope, the Intel Arc Graphics 128EU Mobile has the documented advantages. The absence of measured benchmarks means the verdict rests entirely on theoretical specifications, not on real-world testing.

Where Each One Wins

The NVIDIA N1X 40SM wins on raw compute density. Its FP32 throughput of 24.02 TFLOPS is 5.2x the Intel GPU's 4.608 TFLOPS. Its FP16 throughput of 24.02 TFLOPS is 2.6x the Intel GPU's 9.216 TFLOPS. The texture rate of 750.7 GTexel/s versus 144.0 GTexel/s gives the NVIDIA part a 5.2x lead in texture-heavy workloads. The pixel rate of 93.84 GPixel/s versus 72.00 GPixel/s gives it a 1.3x edge in fill-rate-bound scenarios. The dedicated 128 GB memory pool with 273.2 GB/s bandwidth is a fixed, high-bandwidth resource that the Intel GPU cannot match with system-shared memory.

The Intel Arc Graphics 128EU Mobile wins on API compatibility, as documented by the database. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, while the NVIDIA N1X 40SM lists N/A for all three. The Intel GPU also has a lower base clock of 300 MHz versus 741 MHz, which may indicate different power management characteristics, though TDP is only listed for the Intel part at 28 W. The Intel GPU is built on a 10 nm process at Intel's foundry, while the NVIDIA part uses a 5 nm process at TSMC. The NVIDIA die is listed at 382 mm², while the Intel die size is not recorded.

The NVIDIA part brings ray tracing and tensor cores to the table, with 40 RT cores and 160 tensor cores. The Intel GPU lists null for both RT and tensor cores. This gives the NVIDIA N1X 40SM a structural feature advantage for ray-traced rendering and tensor-accelerated workloads. The NVIDIA part also uses a PCIe 5.0 x16 bus interface, while the Intel GPU uses a Ring Bus interface. Display outputs differ as well: the Intel GPU is listed as portable device dependent, while the NVIDIA part has 1x HDMI.

Architecture Differences

The two GPUs come from entirely different architectural generations and design philosophies. The Intel Arc Graphics 128EU Mobile is based on the Meteor Lake chip using the Xe-LPG architecture, classified under Arc Graphics-M generation. It is built on a 10 nm process at Intel's foundry. The NVIDIA N1X 40SM uses the GB20B chip with Blackwell 2.0 architecture, classified under Blackwell IGP (N1x) generation, and is manufactured on a 5 nm process at TSMC with a 382 mm² die size.

Execution resources differ significantly. The Intel GPU has 1024 shading units, 64 TMUs, and 32 ROPs. The NVIDIA GPU has 5120 shading units, 320 TMUs, and 40 ROPs. That is a 5x difference in shading units, a 5x difference in TMUs, and a 1.25x difference in ROPs. The NVIDIA part also includes 40 RT cores and 160 tensor cores, while the Intel part lists none.

Clock behavior differs between the two. The Intel GPU has a base clock of 300 MHz and a boost of 2250 MHz. The NVIDIA GPU has a base of 741 MHz and a boost of 2346 MHz. The Intel boost clock reaches 96% of the NVIDIA boost clock, despite the large gap in base clocks. This suggests the Intel GPU relies more heavily on boost behavior to reach its performance envelope, while the NVIDIA part starts from a higher idle clock.

Memory architecture is fundamentally different. The Intel GPU uses system-shared memory with a system-dependent bandwidth, meaning its performance is tied to the host platform's memory subsystem. The NVIDIA N1X 40SM has a dedicated 128 GB LPDDR5X pool on a 256-bit bus with a fixed 273.2 GB/s bandwidth. The memory clock is 1067 MHz with an effective rate of 8.5 Gbps. The Intel part has no dedicated memory clock listed beyond "System Shared."

The bus interface also differs. The Intel GPU uses a Ring Bus, while the NVIDIA GPU uses PCIe 5.0 x16. Display outputs are listed as portable device dependent for the Intel part, while the NVIDIA part has 1x HDMI. The Intel GPU is a 28 W IGP, while the NVIDIA TDP is unknown. The NVIDIA part has no power connectors, while the Intel connector field is null.

API support shows a sharp divergence. The Intel Arc Graphics 128EU Mobile supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists DirectX, OpenGL, and Vulkan as N/A. This may reflect a lack of published driver support at the time of data collection, or it may indicate that the NVIDIA IGP is not targeted at the same software ecosystem. The release dates also differ, with the Intel GPU launching on 2023-12-13 and the NVIDIA part on 2026-05-31. The Intel GPU's predecessor is HD Graphics-M, while the NVIDIA part has no predecessor listed.
