Intel Arc 140T Mobile vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results for the Intel Arc 140T Mobile versus the NVIDIA N1X 40SM. Both entries list empty benchmark arrays, zero average benchmark scores, and identical percentile rankings at the 50th percentile against all GPUs. This absence of measured data means the comparison must proceed through architectural specifications, compute throughput figures, and memory subsystem characteristics rather than observed performance deltas.

The most significant numerical gap appears in raw shading throughput. The NVIDIA N1X 40SM delivers 24.02 TFLOPS of FP32 compute, while the Intel Arc 140T Mobile produces 4.813 TFLOPS. This places the NVIDIA part at approximately five times the theoretical single-precision throughput of the Intel part. The FP16 comparison follows a different pattern: the NVIDIA N1X 40SM maintains 24.02 TFLOPS at a 1:1 ratio, whereas the Intel Arc 140T Mobile reaches 9.626 TFLOPS at a 2:1 ratio. The NVIDIA part again leads, but the margin narrows to about 2.5 times.

Texture and pixel throughput show similar disparities. The NVIDIA N1X 40SM achieves 750.7 GTexel/s against 150.4 GTexel/s for the Intel Arc 140T Mobile, a factor of roughly five. Pixel rates sit closer: 93.84 GPixel/s versus 75.20 GPixel/s, a 1.25 times advantage for the NVIDIA part. These figures derive directly from the shading unit counts, TMU counts, and ROP counts recorded in the database.

Clock behavior offers a contrasting observation. The Intel Arc 140T Mobile has a base clock of 300 MHz and a boost clock of 2350 MHz. The NVIDIA N1X 40SM starts from a higher base of 741 MHz but boosts to 2346 MHz, marginally lower than the Intel boost. The Intel part therefore exhibits a much larger boost multiplier, yet the NVIDIA part still commands superior throughput because its wider execution resources more than compensate for the similar boost ceiling.

FAQ

Where Each One Wins

The NVIDIA N1X 40SM wins in every category with recorded numerical data. Its FP32 throughput of 24.02 TFLOPS exceeds the Intel part by roughly five times, making it the stronger choice for compute-heavy workloads that rely on single-precision floating point. The FP16 figure of 24.02 TFLOPS at a 1:1 ratio indicates it sustains full-rate half-precision work, whereas the Intel Arc 140T Mobile's 9.626 TFLOPS at a 2:1 ratio suggests an efficiency advantage for the NVIDIA part in mixed-precision tasks as well.

Memory capacity and bandwidth clearly favor the NVIDIA N1X 40SM. The 128 GB LPDDR5X pool with 273.2 GB/s of bandwidth provides a fixed, high-capacity local memory subsystem. The Intel Arc 140T Mobile shares system memory and lists bandwidth as system dependent, meaning its effective memory performance varies with the host platform rather than being a fixed attribute of the GPU itself.

The NVIDIA part also leads in ray tracing resources with 40 RT cores against 8, and in tensor core availability with 160 units against none recorded for the Intel part. These resource counts position the NVIDIA N1X 40SM ahead for ray-traced rendering and any tensor-accelerated workloads.

The Intel Arc 140T Mobile retains advantages in a few specific areas. Its base clock of 300 MHz allows for a very low idle or low-load operating point, and its 35 W TDP is explicitly recorded, while the NVIDIA part's TDP is unknown. The Intel part also provides broader API coverage with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, whereas the NVIDIA part lists N/A for all three APIs in the database.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Intel Arc 140T Mobile uses the Arrow Lake-H chip with Xe-LPG+ architecture, fabricated on a 5 nm TSMC process. The NVIDIA N1X 40SM uses the GB20B chip with Blackwell 2.0 architecture, also on a 5 nm TSMC process, but with a recorded die size of 382 mm², whereas the Intel die size is unknown.

Memory specifications diverge completely. The Intel part uses system shared memory with system dependent bandwidth. The NVIDIA part carries 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s of fixed bandwidth and a memory clock of 1067 MHz, described as 8.5 Gbps effective.

Compute resources differ by large margins. The NVIDIA N1X 40SM has 5120 shading units, 320 TMUs, 40 ROPs, 40 RT cores, and 160 tensor cores. The Intel Arc 140T Mobile has 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores, with no tensor core figure recorded.

The bus interface also separates the two. The Intel part uses an IGP interface, while the NVIDIA part uses PCIe 5.0 x16. Display outputs differ as well: the Intel part lists portable device dependent outputs, while the NVIDIA part lists a single HDMI output.

The NVIDIA N1X 40SM has a later release date of 2026-05-31, compared to the Intel Arc 140T Mobile's 2025-01-12. Both parts are listed as Active in production status. Neither part has a launch MSRP recorded in the database.

Architecture Differences

The Intel Arc 140T Mobile belongs to the Arc Graphics-M (Arrow Lake) generation and uses the Xe-LPG+ architecture. The NVIDIA N1X 40SM belongs to the Blackwell IGP (N1x) generation and uses the Blackwell 2.0 architecture. Both are fabricated by TSMC on a 5 nm process, but the underlying designs diverge substantially.

The NVIDIA N1X 40SM records a die size of 382 mm², while the Intel die size is unknown. Transistor counts for both parts are listed as unknown. The NVIDIA part includes a dedicated tensor core array of 160 units, a feature absent from the Intel part's recorded specifications. Ray tracing hardware differs by a factor of five: 40 RT cores versus 8.

The FP16 execution model highlights an architectural difference. The Intel Arc 140T Mobile achieves 9.626 TFLOPS at a 2:1 ratio, meaning it processes half-precision work at half the rate of full-precision work. The NVIDIA N1X 40SM achieves 24.02 TFLOPS at a 1:1 ratio, meaning it processes FP16 at the same rate as FP32. This indicates a fundamentally different approach to mixed-precision throughput.

The memory architecture also differs at a structural level. The Intel part shares system memory and has no dedicated VRAM pool. The NVIDIA part integrates 128 GB of LPDDR5X locally, with a 256-bit bus and fixed bandwidth. This makes the NVIDIA part self-contained for memory operations, while the Intel part depends on the host system's memory configuration.

The Verdict

For workloads that demand maximum compute throughput, the NVIDIA N1X 40SM is the clear choice based on recorded data. Its 24.02 TFLOPS FP32 figure, 750.7 GTexel/s texture rate, and 93.84 GPixel/s pixel rate all exceed the Intel Arc 140T Mobile's corresponding values by substantial margins. The 160 tensor cores and 40 RT cores add acceleration paths that the Intel part cannot match, given its 8 RT cores and no recorded tensor core count.

The NVIDIA N1X 40SM also suits applications that require large, fixed local memory. The 128 GB LPDDR5X configuration with 273.2 GB/s of bandwidth provides a consistent memory environment. The Intel Arc 140T Mobile's system shared memory approach means its memory performance is not a fixed property of the GPU, and the database records bandwidth as system dependent.

The Intel Arc 140T Mobile remains relevant for specific use cases. Its 35 W TDP is explicitly recorded, making it a lower-power option on paper, though the NVIDIA part's TDP is unknown so a direct power comparison is not possible. Its API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 is documented, while the NVIDIA part lists N/A for all three, suggesting the Intel part has broader software interface coverage in the database.

The data indicates the NVIDIA N1X 40SM is the higher-performance part across all measured compute and memory specifications. The Intel Arc 140T Mobile offers a lower recorded power envelope and a more conventional API set. Both parts sit at the 50th percentile against all GPUs, but with no benchmark scores recorded, that percentile carries no differentiating information. Users prioritizing raw throughput, local memory capacity, tensor acceleration, and ray tracing resources should select the NVIDIA N1X 40SM. Users prioritizing a documented 35 W power limit and broader API compatibility should consider the Intel Arc 140T Mobile.
