Intel Arc B570 vs Intel Arc Graphics 4 Xe Mobile Comparison

Intel Arc B570 and Intel Arc Graphics 4 Xe Mobile occupy opposite ends of the Intel graphics spectrum. The B570 is a dedicated desktop add-in board built on the Xe2-HPG architecture, while the 4 Xe Mobile is an integrated processor graphics solution on the Xe3-LPG architecture. The recorded data shows a decisive performance gap, but the comparison reveals distinct roles for each part.

Where Each One Wins

The Intel Arc B570 wins in every benchmark category where data exists. It is a discrete GPU with 2304 shading units, 144 texture mapping units, and 80 render output units. Its FP32 compute rating is 11.52 TFLOPS, and its texture fill rate is 360.0 GTexel/s. The Arc Graphics 4 Xe Mobile, by contrast, is an integrated part with 512 shading units, 32 TMUs, and 16 ROPs. It delivers 2.355 TFLOPS FP32 and a texture rate of 73.60 GTexel/s. The B570 holds a 4.5x advantage in shading units and a 4.89x advantage in FP32 throughput.

The B570 also wins on memory. It uses 10 GB of dedicated GDDR6 on a 160-bit bus, providing 380.0 GB/s of bandwidth. The 4 Xe Mobile uses system shared memory with bandwidth described as system dependent. This makes the B570 suitable for memory-intensive workloads like high-resolution textures and large compute buffers, while the mobile part must share bandwidth with the CPU and other system components.

The mobile part wins in power efficiency by design. Its TDP is 25 W, compared to the B570's 150 W. It requires no power connectors and is an IGP, meaning it is soldered into the processor package. The B570 needs a 1x 8-pin power connector and a suggested 450 W power supply. The mobile part also wins in physical footprint, with no separate slot width, dimensions, or card length. It is built into the system, whereas the B570 is a dual-slot card measuring 272 mm in length and 115 mm in height.

The Verdict

The data indicates a clear choice based on use case. The Intel Arc B570 is the only option for users who need dedicated graphics performance in a desktop system. Its benchmark scores place it in the 65th percentile of all GPUs in the database, with an average benchmark score of 20556. The Arc Graphics 4 Xe Mobile sits in the 50th percentile with no recorded benchmark scores and an average score of zero in the database.

The B570 is the pick for gaming, 3D rendering, and compute tasks. Its DirectX 12 Ultimate support, 18 ray tracing cores, and 64.1 TFLOPS of FP16 throughput (23.04 TFLOPS FP16 figure in the pack) give it a wide range of capabilities. The 4 Xe Mobile is the pick for thin-and-light laptops where power draw and heat are the primary constraints. Its 25 W TDP and integrated design make it suitable for basic graphics, video playback, and light productivity, but the database contains no benchmark evidence of its performance level.

The B570's nearest rivals in the database are the NVIDIA GeForce RTX 3070 Mobile with an average score of 20534 (0.1% behind the B570), the Intel Arc A750 at 20582 (0.1% ahead), the NVIDIA Quadro M4000M at 20480 (0.4% behind), and the AMD Radeon R9 M390X at 20662 (0.5% ahead). These deltas are all within one percent, meaning the B570 sits in a tightly competitive band. The mobile part has no recorded rivals, so its relative standing cannot be assessed beyond its 50th percentile placement.

Head-to-Head Benchmarks

The head-to-head benchmark array is empty in the database, so direct same-test comparisons are not possible. However, the individual benchmark records for the B570 provide a reference point. In 3DMark Steel Nomad DX12, the B570 scores 2649. In Geekbench OpenCL, it scores 83514, and in Geekbench Vulkan, it scores 96844. The PassMark suite shows a G3D score of 14195, a G2D score of 661, and a GPU compute score of 7281. The mobile part has no entries in any of these tests.

The compute gap is the largest measurable difference. The B570's FP32 rating of 11.52 TFLOPS is 4.89x the mobile part's 2.355 TFLOPS. Its texture rate of 360.0 GTexel/s is 4.89x the 73.60 GTexel/s of the mobile part. Its pixel rate of 200.0 GPixel/s is 5.43x the 36.80 GPixel/s of the mobile part. These ratios reflect the difference in execution resources: 2304 vs 512 shading units, 144 vs 32 TMUs, and 80 vs 16 ROPs.

The ray tracing gap is also substantial. The B570 has 18 ray tracing cores, while the mobile part has 4. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level features are identical. The difference lies in the amount of hardware available to process those workloads.

Clock behavior differs as well. The B570 runs at a constant 2500 MHz for both base and boost. The mobile part has a base clock of 300 MHz and a boost clock of 2300 MHz. The wide boost range on the mobile part suggests it scales heavily with thermal and power headroom, while the B570 maintains a flat clock profile.
