Intel Arc Graphics 48EU Mobile vs NVIDIA N1X 48SM Comparison

The database records no head-to-head benchmark scores for the Intel Arc Graphics 48EU Mobile and the NVIDIA N1X 48SM. Both parts sit at the 50th percentile in the overall GPU distribution and both have an average benchmark score of 0, so the recorded specification data is the basis for comparison. Intel's part is a Meteor Lake chip with Xe-LPG architecture, while NVIDIA's part is a GB20B chip with Blackwell 2.0 architecture.

Where Each One Wins

With no recorded benchmark wins on either side, the use-case split comes from specification advantages. NVIDIA N1X 48SM wins every raw throughput category in the recorded data. It delivers 28.83 TFLOPS FP32, 28.83 TFLOPS FP16 (1:1), 900.9 GTexel/s texture rate, and 112.6 GPixel/s pixel rate. It has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 192 tensor cores. Intel Arc Graphics 48EU Mobile wins the compatibility and power categories. It lists DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4 support, while NVIDIA lists N/A for those APIs. Intel also records a 28 W TDP, while NVIDIA's TDP is unknown.

For applications that need documented DirectX 12 (12_1), OpenGL 4.6, or Vulkan 1.4 paths, the Intel part is the only one with that support in this pairing. For applications that need high shader throughput, texture fill, ray tracing resources, tensor resources, or memory bandwidth, the NVIDIA part is the only one with those resources recorded. The memory comparison also favors NVIDIA: 128 GB of LPDDR5X on a 256-bit bus with 273.2 GB/s bandwidth, versus Intel's System Shared memory with System Dependent bandwidth.

Architecture Differences

The two GPUs are built on different processes and foundries. Intel uses a 10 nm process at Intel. NVIDIA uses a 5 nm process at TSMC. Intel's chip is Meteor Lake, from the Arc Graphics-M (Meteor Lake) generation, with Xe-LPG architecture. NVIDIA's chip is GB20B, from the Blackwell IGP (N1x) generation, with Blackwell 2.0 architecture. NVIDIA records a die size of 382 mm²; Intel does not record a die size. NVIDIA's transistor count is unknown, and Intel does not list one.

Memory architecture is completely different. Intel uses System Shared memory with System Dependent bandwidth and a Ring Bus interface. NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus, with a memory clock of 1067 MHz and 8.5 Gbps effective data rate. The resulting memory bandwidth is 273.2 GB/s. NVIDIA's bus interface is PCIe 5.0 x16.

Compute resources differ by a wide margin. Intel has 384 shading units, 24 TMUs, and 8 ROPs. NVIDIA has 6144 shading units, 384 TMUs, and 48 ROPs. NVIDIA also lists 48 RT cores and 192 tensor cores; Intel's RT core and tensor core counts are not populated. Clock speeds are also higher on NVIDIA: base 741 MHz and boost 2346 MHz, versus Intel's base 300 MHz and boost 1800 MHz.

Feature and output records differ as well. Intel supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. NVIDIA lists N/A for DirectX, OpenGL, and Vulkan. Intel's display output is Portable Device Dependent; NVIDIA's display output is 1x HDMI. Both parts use an IGP slot width. Intel has a 28 W TDP; NVIDIA's TDP is unknown. NVIDIA lists no power connectors; Intel's power connector field is not populated. Intel's predecessor is HD Graphics-M; NVIDIA has no predecessor listed. Neither part lists a successor. Both parts are Active in production, with Intel released on 2023-12-13 and NVIDIA on 2026-05-31.

Head-to-Head Benchmarks

The database has no head-to-head benchmark entries for this pair, so the closest available head-to-head data are the recorded rate figures. NVIDIA leads every measured throughput category. FP32 performance is 28.83 TFLOPS for NVIDIA versus 1,382.4 GFLOPS for Intel. FP16 performance is 28.83 TFLOPS (1:1) versus 2.765 TFLOPS (2:1). That ratio difference matters: NVIDIA's FP16 output matches its FP32 output, while Intel's FP16 output is recorded at a 2:1 rate relative to its FP32 work.

Texture rate is 900.9 GTexel/s versus 43.20 GTexel/s. Pixel rate is 112.6 GPixel/s versus 14.40 GPixel/s. The shading resources follow the same direction: 6144 versus 384 shading units, 384 versus 24 TMUs, and 48 versus 8 ROPs. NVIDIA's 48 RT cores and 192 tensor cores have no Intel counterpart in the recorded data.

Memory bandwidth is another large NVIDIA advantage. NVIDIA records 273.2 GB/s over a 256-bit LPDDR5X bus, with a memory clock of 1067 MHz and 8.5 Gbps effective. Intel's memory bandwidth is System Dependent and its memory clock is System Shared. NVIDIA also has 128 GB of memory, while Intel's memory size is System Shared.

Clock speeds favor NVIDIA. NVIDIA's base clock is 741 MHz, and its boost clock is 2346 MHz. Intel's base clock is 300 MHz, and its boost clock is 1800 MHz. On the Intel side, the measurable wins are API coverage and the power record. Intel supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4; NVIDIA lists N/A for each. Intel has a recorded TDP of 28 W; NVIDIA's TDP is unknown. Both parts have an average benchmark score of 0 and a 50th percentile position, which reflects the absence of benchmark entries rather than a measured performance tie.

The Verdict

Strictly from the recorded data, the NVIDIA N1X 48SM is the raw performance choice. It has 6144 shading units, 48 RT cores, 192 tensor cores, 28.83 TFLOPS FP32, and 273.2 GB/s of memory bandwidth. The Intel Arc Graphics 48EU Mobile is the compatibility and low-power choice. It is the only part in this pairing with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4 support, and it has a recorded 28 W TDP.

Because no direct benchmark scores are recorded, the verdict cannot rank actual game or compute results. The specification data shows NVIDIA winning all raw throughput and memory categories, while Intel wins the API compatibility and power record categories. Both parts are Active in production, with Intel released on 2023-12-13 and NVIDIA on 2026-05-31. The recorded percentile places both at 50, and the average benchmark score for both is 0.
