Intel Arc Graphics 64EU Mobile vs Intel Arc Pro B370 Comparison

Intel Arc Graphics 64EU Mobile and Intel Arc Pro B370 are both integrated graphics solutions from Intel, but they target different segments of the mobile market. The database records the 64EU Mobile as a Meteor Lake part using the Xe-LPG architecture on a 10 nm process, while the Arc Pro B370 is a Panther Lake chip built on Xe3-LPG at 3 nm. The recorded data shows substantial differences in compute resources, clock behavior, and feature support, which translate into distinct performance profiles. This analysis relies strictly on the recorded specifications and available benchmark context.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark scores for these two parts, as the benchmark arrays for both items are empty. However, the recorded specifications provide enough data to project relative performance in several key workloads. The most decisive difference is in raw compute throughput. The Arc Pro B370 delivers 6.144 TFLOPS of FP32 performance, while the Arc Graphics 64EU Mobile delivers 1.792 TFLOPS. That places the B370 at roughly 3.4 times the FP32 throughput of the 64EU Mobile, a gap that will dominate any shader-bound workload.

Texture and pixel processing follow the same pattern. The B370 records a texture rate of 96.00 GTexel/s against 56.00 GTexel/s for the 64EU Mobile, a 71% advantage. Pixel rate for the B370 is 48.00 GPixel/s versus 28.00 GPixel/s for the 64EU Mobile, a 71% advantage as well. These figures come directly from the shading unit counts and clock speeds, so the relative gaps are consistent across the board.

FP16 performance shows an even larger disparity. The B370 records 12.29 TFLOPS (2:1) while the 64EU Mobile records 3.584 TFLOPS (2:1). That is a 3.4x difference, matching the FP32 ratio. Applications that can use packed FP16 math will see the same scaling as FP32 workloads.

Clock behavior favors the B370 on paper. Both parts have a 300 MHz base clock, but the boost clock differs: 2400 MHz for the B370 versus 1750 MHz for the 64EU Mobile. The B370 boosts 37% higher, which partially explains its higher throughput despite only a 2.5x increase in shading units (1280 versus 512). The combination of more shaders and a higher boost clock produces the observed compute gaps.

The B370 also adds dedicated ray tracing hardware, listed as 10 RT cores, while the 64EU Mobile has no recorded RT core count. Any ray-traced workload will favor the B370 by a margin not captured in the shader-based metrics. The 64EU Mobile has no tensor core listing either, and the B370 also has no tensor core count, so AI acceleration via dedicated tensor hardware is not part of the recorded comparison.

Where Each One Wins

The Arc Graphics 64EU Mobile wins in power efficiency relative to its capabilities, though the data does not show a direct efficiency metric. Its 65 W TDP is higher than the B370's 25 W TDP, but the 64EU Mobile is built on a 10 nm process and has fewer execution resources. The 64EU Mobile is an integrated part with a Ring Bus interface, designed for Meteor Lake laptops where the GPU shares system memory and power budget with the CPU.

The Arc Pro B370 wins in every raw performance category recorded. It has more shading units (1280 versus 512), more texture mapping units (40 versus 32), more ROPs (20 versus 16), and a higher boost clock. Its pixel rate, texture rate, FP32 throughput, and FP16 throughput all exceed the 64EU Mobile. The B370 also supports DirectX 12 Ultimate (12_2) while the 64EU Mobile supports DirectX 12 (12_1), meaning the B370 can run features like mesh shaders and variable rate shading that require 12_2 support.

For use cases like gaming at higher settings, 3D rendering, or compute workloads, the B370 is the clear choice based on recorded data. For light workloads such as video playback, office productivity, or basic 2D acceleration, the 64EU Mobile's lower resource footprint and 65 W TDP may be sufficient, though the B370's 25 W TDP suggests it will consume less power while delivering more performance. The B370 also has no power connectors while the 64EU Mobile has no recorded power connector requirement, indicating both are fully integrated parts.

The B370's 3 nm process node versus the 64EU Mobile's 10 nm node gives the B370 a density advantage, though the exact transistor counts are not recorded for either part. The B370 lists "unknown" for transistor count and die size, and the 64EU Mobile lists null for both. This process difference likely explains the B370's ability to pack 1280 shading units into a 25 W TDP envelope.

Architecture Differences

The two parts come from different architecture generations. The Arc Graphics 64EU Mobile uses Xe-LPG, the architecture found in Meteor Lake. The Arc Pro B370 uses Xe3-LPG, the architecture in Panther Lake. The 64EU Mobile is part of the Arc Graphics-M generation, while the B370 is part of the Arc Graphics-WM (Panther Lake) generation. This generation gap accounts for several feature differences.

DirectX support differs. The 64EU Mobile supports DirectX 12 (12_1), while the B370 supports DirectX 12 Ultimate (12_2). Both support OpenGL 4.6 and Vulkan 1.4. The B370 adds ray tracing cores, with 10 RT cores recorded, while the 64EU Mobile has no RT core count. This means hardware-accelerated ray tracing is only available on the B370.

Memory configuration is identical in structure: both use System Shared memory, with type, bus width, and bandwidth all listed as System Shared or System Dependent. Neither part has dedicated VRAM. The actual bandwidth depends on the host system's memory configuration, which is not recorded.

Process node is a major difference: 10 nm for the 64EU Mobile versus 3 nm for the B370. The B370's newer process allows for higher clock speeds (2400 MHz boost versus 1750 MHz) and more execution units within a lower TDP (25 W versus 65 W). The foundry for both is Intel.

The bus interface differs. The 64EU Mobile uses Ring Bus, while the B370 uses IGP. Both are integrated graphics, with no slot width recorded beyond "IGP" for each. Display outputs are listed as Portable Device Dependent for both, meaning the actual connectors depend on the laptop or device design.

The B370 has a predecessor listed as HD Graphics-WM, while the 64EU Mobile has a predecessor of HD Graphics-M. Both are Active in production status. Release dates differ: the 64EU Mobile launched on 2023-12-13, and the B370 launched on 2026-01-26.

The Verdict

The recorded data points to a single conclusion for performance: the Arc Pro B370 outperforms the Arc Graphics 64EU Mobile in every measurable category. FP32 throughput is 3.4x higher, FP16 throughput is 3.4x higher, texture rate is 71% higher, and pixel rate is 71% higher. The B370 has 2.5x the shading units, 25% more TMUs, 25% more ROPs, and a 37% higher boost clock. It also adds 10 RT cores for hardware ray tracing and supports DirectX 12 Ultimate.

The 64EU Mobile's only advantages are its earlier release date and its lower absolute resource count, which may translate to simpler driver integration in older Meteor Lake platforms. Its 65 W TDP is higher than the B370's 25 W TDP, so it does not win on power draw.

For a system builder choosing between the two, the B370 is the superior part for any workload that uses shaders, textures, or ray tracing. The 64EU Mobile is a capable integrated GPU for basic tasks, but the data shows no scenario where its recorded specifications exceed those of the B370. The B370's newer architecture, higher clock speeds, and larger execution resource pool make it the better choice for laptops requiring integrated graphics performance.

The only caveat is that the B370 is a newer part with a later release date, so platform availability may differ. But strictly from the recorded specifications, the Arc Pro B370 is the stronger performer in all categories.
