Intel Arc Graphics 1 Xe Mobile vs Intel Arc Pro B50 Comparison

Head-to-Head Benchmarks

The recorded data contains a full set of benchmark results for the Intel Arc Pro B50, while the Intel Arc Graphics 1 Xe Mobile has no individual benchmark entries in the database. This limits direct comparisons, but the available numbers for the Arc Pro B50 establish a clear performance tier.

The Arc Pro B50 achieves a 3DMark Steel Nomad DX12 score of 1,604. In PassMark tests, it records 144 in DirectX 9, 100 in DirectX 11, 64 in DirectX 12, and 58 in DirectX 10. The PassMark G3D score reaches 12,553, with a GPU compute score of 6,037 and a G2D score of 717.

The average benchmark score for the Arc Pro B50 sits at 2,660. Its nearest rival in the database is the NVIDIA GeForce GT 1030, which averages 2,662, placing the Arc Pro B50 just 0.1% behind. The NVIDIA Quadro K1100M averages 2,664, a 0.2% gap. The Arc Pro B50 leads the NVIDIA GeForce GT 440, which averages 2,645, by 0.6%. The database also lists the NVIDIA GeForce RTX 5070 SUPER at an average of 2,690, which is 1.1% ahead of the Arc Pro B50.

These deltas are remarkably small. The Arc Pro B50 sits within a tight band of roughly 1.7% between the slowest and fastest of its four nearest rivals. The percentile data places the Arc Pro B50 at the 17th percentile among all GPUs, indicating that most recorded graphics cards outperform it. The Intel Arc Graphics 1 Xe Mobile holds a 50th percentile rating, but without benchmark scores, this percentile cannot be verified against measured results.

The Arc Pro B50's peak theoretical rates are substantial for its class. Pixel throughput reaches 41.60 GPixel/s, while texture rate hits 332.8 GTexel/s. FP32 compute is rated at 10.65 TFLOPS, with FP16 at 21.30 TFLOPS using a 2:1 ratio. The Intel Arc Graphics 1 Xe Mobile, by contrast, is rated at 9.200 GPixel/s, 18.40 GTexel/s, 588.8 GFLOPS FP32, and 1,177.6 GFLOPS FP16. These figures show a large gap in raw throughput, with the Arc Pro B50 delivering roughly 4.5 times the pixel rate, 18 times the texture rate, and 18 times the FP32 compute of the mobile part.

The Verdict

The data supports a clear split based on platform and workload. The Intel Arc Pro B50 is a discrete dual-slot card with 16 GB of GDDR6 memory, a 128-bit memory bus, and 224.0 GB/s of bandwidth. Its benchmark results, while modest relative to the broader GPU market, place it in the company of entry-level discrete cards like the GeForce GT 1030. The 17th percentile ranking confirms that it is not a high-performance part, but it does offer a complete, standalone graphics solution with a 70 W TDP and a suggested power supply of 250 W.

The Intel Arc Graphics 1 Xe Mobile is an integrated graphics processor built into the Wildcat Lake chip. It uses system shared memory, has no dedicated VRAM, and draws 25 W as part of the overall chip power envelope. Its 128 shading units, 8 TMUs, and 4 ROPs are a fraction of the Arc Pro B50's 2,048 shading units, 128 TMUs, and 16 ROPs. The mobile part also has 1 ray tracing core versus 16 on the Arc Pro B50.

For users who need a discrete card with dedicated GDDR6 memory, four mini-DisplayPort 2.1 outputs, and PCIe 5.0 x8 connectivity, the Arc Pro B50 is the only viable choice between these two. The mobile integrated GPU is not a standalone product; it is part of a processor and cannot be installed in a desktop system. The Arc Pro B50 is a physical card measuring 167 mm in length, 69 mm in height, and 40 mm in width, and it occupies a dual-slot width.

The launch MSRP of the Arc Pro B50 is 349 USD. The mobile part has no listed launch price, as it ships inside a processor. Neither part should be selected for high-end gaming or compute based on the recorded data; the Arc Pro B50's average score of 2,660 is effectively tied with the GT 1030, a card from a much older generation.

Architecture Differences

The two GPUs come from different Intel architectures. The Intel Arc Graphics 1 Xe Mobile uses Xe3-LPG architecture on Intel's 3 nm process, with the chip named Wildcat Lake. It belongs to the Arc Graphics-M (Wildcat Lake) generation. The Intel Arc Pro B50 uses Xe2-HPG architecture on TSMC's 5 nm process, with the chip named BMG-G21, and belongs to the Battlemage (Pro Series) generation.

Transistor counts differ enormously. The Arc Pro B50 packs 19,600 million transistors on a 272 mm² die, yielding a transistor density of 72.1 million transistors per square millimeter. The mobile part's transistor count and die size are listed as unknown in the database. The Arc Pro B50 is fabricated by TSMC, while the mobile GPU is fabricated by Intel.

The mobile GPU integrates 1 ray tracing core, while the Arc Pro B50 has 16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical.

The Arc Pro B50 has a base clock of 1700 MHz and a boost clock of 2600 MHz, with memory running at 1750 MHz (14 Gbps effective). The mobile GPU has a base clock of 300 MHz and a boost clock of 2300 MHz, with memory clock listed as system shared. The boost clock gap of 300 MHz is modest compared to the differences in core counts and memory systems.

Where Each One Wins

The Intel Arc Pro B50 wins in every category where measured data exists. It has dedicated GDDR6 memory with 224.0 GB/s bandwidth, which is a fixed and predictable resource for graphics workloads. Its 10.65 TFLOPS FP32 compute and 332.8 GTexel/s texture rate are far beyond the mobile GPU's 588.8 GFLOPS and 18.40 GTexel/s. The 16 ray tracing cores give it a hardware ray tracing advantage over the mobile GPU's single core. The four mini-DisplayPort 2.1 outputs support multi-display professional setups, and the 16 GB frame buffer is suitable for large datasets or high-resolution textures.

The Arc Pro B50 also wins on clock behavior, with a 2600 MHz boost versus 2300 MHz on the mobile part. Its pixel rate of 41.60 GPixel/s is 4.5 times the mobile GPU's 9.200 GPixel/s. The dual-slot cooling and 70 W TDP indicate a sustained, standalone operation profile, while the mobile GPU is constrained by the thermal and power limits of the host processor.

The Intel Arc Graphics 1 Xe Mobile wins on integration and efficiency. It draws 25 W, which is less than half the Arc Pro B50's 70 W, and requires no additional power connectors or power supply headroom. It is an IGP, so it adds no physical card footprint and works in portable devices. Its 3 nm Intel process is smaller than the 5 nm TSMC node used for the Arc Pro B50, which suggests a denser, more power-efficient design for its intended mobile role. The mobile GPU also has a higher percentile ranking (50th versus 17th), though this is based on no recorded benchmarks.

The mobile GPU's system shared memory means no separate VRAM purchase or allocation is needed, and bandwidth scales with the host system's memory configuration. This makes it a flexible option for thin-and-light systems where a discrete card is impossible. The Arc Pro B50, by contrast, is a fixed, self-contained graphics solution that does not rely on host memory bandwidth.

For users selecting between these two, the choice is structural. The Arc Pro B50 is a discrete card for desktop or workstation builds that require a dedicated, benchmarked GPU. The mobile GPU is an integrated component for portable devices, with no standalone purchase path and no measured performance data in the database.
