Intel Arc G3 vs Intel Arc Pro B370 Comparison

The Intel Arc G3 and the Intel Arc Pro B370 are two mobile integrated graphics parts that, on paper, appear nearly identical. Both are built on the same Panther Lake chip and the Xe3-LPG architecture, and the recorded data shows matching specifications across every measurable internal component. The primary distinction between them lies in their generation designation and their release timing within the database.

Where Each One Wins

The benchmark results in the database show no performance split between these two parts. The recorded data indicates that both the Intel Arc G3 and the Intel Arc Pro B370 deliver an identical average benchmark score of 0, and both hold the same percentile position at 50 when ranked against all GPUs. In head-to-head benchmark comparisons, neither part records a single win over the other. The wins counter for each item stands at zero, and the head-to-head benchmark list is empty. This means that, from the perspective of measured performance, there is no use case where one part outperforms the other. They are, for all practical purposes, equal in compute capability.

The practical implications of this data are straightforward. For tasks that rely on the GPU's shading units, texture mapping units, or raster output units, the two parts will produce the same results. The Arc G3 and the Arc Pro B370 each use 1280 shading units, 40 texture mapping units, and 20 raster output units. The pixel fill rate is recorded at 48.00 GPixel/s for both, and the texture fill rate is 96.00 GTexel/s for both. The floating-point performance matches as well, with each part delivering 6.144 TFLOPS for FP32 operations and 12.29 TFLOPS for FP16 operations using a 2:1 ratio. There is no workload category, whether it is rasterization, texture-heavy rendering, or general compute, where the data suggests one part has an advantage.

The only area where the data shows a difference is in the generation field. The Arc G3 belongs to the Arc Graphics-M generation for Panther Lake, while the Arc Pro B370 belongs to the Arc Graphics-WM generation for the same chip. This is a classification difference, not a performance difference. The database does not contain any benchmark results that would indicate the WM designation offers any measurable benefit in real-world tasks. The user of either part should expect identical performance characteristics.

Architecture Differences

The architecture of both GPUs is based on the same Panther Lake chip. The architecture field for both is listed as Xe3-LPG, and the chip is identified as Panther Lake for both. The process node is identical at 3 nm, and the foundry is Intel for both parts. The transistor count and die size are listed as unknown in the database, so no comparison can be made on those physical characteristics.

The clock behavior is also consistent. Both parts have a base clock of 300 MHz and a boost clock of 2400 MHz. The memory clock is listed as System Shared for both, which means the memory speed is dependent on the system configuration rather than a fixed specification. The memory size, type, and bus width are all listed as System Shared for both parts, and the bandwidth is listed as System Dependent. This indicates that both GPUs rely entirely on the host system's memory, and their performance will be tied to the memory subsystem of the device they are installed in.

The compute unit layout is identical. Both parts feature 10 ray tracing cores, and neither has dedicated tensor cores listed in the database. The API support is the same for both, with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power characteristics match as well, with both parts having a TDP of 25 W, a slot width of IGP, and no power connectors. The bus interface is IGP for both, meaning they are integrated into the processor rather than being discrete add-in cards.

The display outputs are listed as Portable Device Dependent for both, which indicates that the actual connectivity options depend on the specific portable device that hosts the GPU. The production status for both is Active, meaning they are currently in production. The only architectural difference that the data reveals is the generation label and the release date. The Arc Pro B370 has a predecessor listed as HD Graphics-WM, while the Arc G3 has no predecessor listed. This is a lineage difference, but it does not affect the architectural specifications of the parts themselves.

Specification Differences

The specification fields in the database reveal only a handful of differences between the two parts. The name differs, with one being Intel Arc G3 and the other being Intel Arc Pro B370. The generation field differs: the Arc G3 is listed under Arc Graphics-M, while the Arc Pro B370 is listed under Arc Graphics-WM. The release date differs, with the Arc Pro B370 releasing on 2026-01-26T17:00:00.000Z and the Arc G3 releasing on 2026-05-31T17:00:00.000Z. The Arc Pro B370 has a predecessor listed as HD Graphics-WM, while the Arc G3 has no predecessor listed. All other specification fields, including the chip, architecture, process node, foundry, clocks, memory, shading units, texture mapping units, raster output units, ray tracing cores, pixel rate, texture rate, FP32 throughput, FP16 throughput, TDP, slot width, power connectors, bus interface, display outputs, APIs, production status, and launch MSRP, are identical or absent in the same way. Neither part has a launch MSRP listed in the database.

Head-to-Head Benchmarks

The head-to-head benchmark data for these two parts is entirely empty. There are no recorded benchmark entries in the head-to-head benchmark list, and the wins count for each part is zero. The average benchmark score for both is 0, which indicates that the database has no performance measurements for either part. The percentile versus all GPUs is 50 for both, which places them in the middle of the distribution, but this is a static ranking that does not change based on any measured performance. The nearest rivals list is empty for both parts, so there is no comparative performance data against other GPUs in the database.

When examining the theoretical throughput numbers, the two parts are exactly equal. The pixel rate is 48.00 GPixel/s for both, which means they can process the same number of pixels per second. The texture rate is 96.00 GTexel/s for both, meaning texture sampling and filtering performance is identical. The FP32 throughput is 6.144 TFLOPS for both, which is the peak single-precision floating-point compute rate. The FP16 throughput is 12.29 TFLOPS for both, achieved through a 2:1 ratio, which doubles the throughput for half-precision operations. These numbers are the only performance indicators available in the database, and they show no divergence between the two parts.

The clock speeds reinforce this equivalence. Both parts run at a base clock of 300 MHz and a boost clock of 2400 MHz. The boost clock is the maximum frequency the GPU can reach under load, and since it is the same for both, the peak performance ceiling is the same. The memory bandwidth is System Dependent for both, which means the actual bandwidth will vary based on the system memory configuration, but it will vary in the same way for both parts when installed in the same system. The memory bus width is System Shared for both, so there is no fixed bus width difference to separate them.

The Verdict

The data in the database indicates that the Intel Arc G3 and the Intel Arc Pro B370 are functionally equivalent GPUs. Every compute-related specification matches exactly: the same shading unit count, the same texture mapping unit count, the same raster output unit count, the same ray tracing core count, the same clock speeds, the same pixel rate, the same texture rate, and the same FP32 and FP16 throughput. The TDP is the same at 25 W, the slot width is the same at IGP, and the power connector requirement is the same at None. The bus interface is IGP for both, and the display outputs are Portable Device Dependent for both. The API support is identical across DirectX, OpenGL, and Vulkan.

The recorded benchmark data shows no performance gap. Both parts have an average benchmark score of 0, both hold a percentile position of 50, and neither has any wins in head-to-head comparisons. There are no nearest rivals listed for either part, so there is no external performance context to draw from. The choice between these two parts, based on the data, comes down to which generation label is preferred or which release date matters more. The Arc Pro B370 was released earlier, on 2026-01-26T17:00:00.000Z, and it has a predecessor in the HD Graphics-WM line. The Arc G3 was released later, on 2026-05-31T17:00:00.000Z, and it has no predecessor listed. For a user selecting between the two, the data suggests that the performance will be identical, and the deciding factors would be any system-level compatibility or driver support differences that are not captured in the specifications. The recorded data does not provide any reason to prefer one over the other on the basis of speed, efficiency, or feature set. They are twin parts in different packaging.
