Intel Arc Graphics 48EU Mobile vs Intel Arc Pro B65 Comparison

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the Intel Arc Graphics 48EU Mobile and the Intel Arc Pro B65. Both entries carry zero recorded benchmark scores and zero wins in direct comparison. This absence of data is itself informative. The two GPUs occupy different segments of Intel's graphics lineup, one designed for mobile integration and the other for professional desktop workloads, so direct comparison runs are not yet available in the recorded measurements.

What the data does show is a massive gap in raw compute specifications. The Arc Pro B65 delivers 12.29 TFLOPS of FP32 performance, while the Arc Graphics 48EU Mobile reaches 1,382.4 GFLOPS, which converts to roughly 1.38 TFLOPS. The difference is approximately 8.9 times in favor of the Pro card. FP16 throughput tells a similar story: the Pro B65 reaches 24.58 TFLOPS (2:1) versus 2.765 TFLOPS (2:1) for the mobile part.

Pixel and texture rates reinforce the same conclusion. The Arc Pro B65 outputs 192.0 GPixel/s and 384.0 GTexel/s. The Arc Graphics 48EU Mobile manages 14.40 GPixel/s and 43.20 GTexel/s. These are not incremental differences. They represent different classes of hardware entirely.

Memory bandwidth is another decisive separator. The Pro B65 uses 32 GB of GDDR6 on a 256-bit bus, delivering 608.0 GB/s. The mobile part shares system memory with no dedicated VRAM, and its bandwidth is listed as "System Dependent." That dependency means real-world throughput varies with the host platform, but it cannot approach the dedicated bandwidth of the Pro card.

The absence of benchmark scores means percentile rankings are also neutral. Both GPUs sit at the 50th percentile against all GPUs in the database, but that figure is a placeholder given no actual test data exists. The nearest rivals fields are empty for both entries, so no relative performance context from direct comparisons is available.

Given the specification sheet alone, the Arc Pro B65 is positioned to dominate in every measurable compute category. The mobile part's advantages lie elsewhere: power consumption and integration. The mobile GPU carries a 28 W TDP, while the Pro card requires 200 W plus a separate 8-pin power connector. The mobile part is an IGP, meaning it occupies no expansion slot and requires no additional power cabling. The Pro card is a dual-slot PCIe 5.0 x16 add-in board.

The data implies that any benchmark run would show the Pro B65 winning every frame rate, render time, and compute throughput test by a wide margin. The mobile part would win any efficiency or thermal test measured per watt, though the database does not record such metrics directly.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Intel Arc Graphics 48EU Mobile is built on the Xe-LPG architecture and uses the Meteor Lake chip, which belongs to the "Arc Graphics-M (Meteor Lake)" generation. The Intel Arc Pro B65 uses the Xe2-HPG architecture with the BMG-G21 chip, part of the "Battlemage (Pro Series)" generation.

The process technology differs substantially. The mobile part uses Intel's 10 nm node, while the Pro B65 uses TSMC's 5 nm process. The Pro chip contains 19,600 million transistors on a 272 mm² die, giving a transistor density of 72.1M per mm². The mobile chip has no transistor count or die size listed in the database, but the architectural gap is clear from the compute units alone.

Shader resources scale dramatically between the two. The Arc Graphics 48EU Mobile has 384 shading units, 24 texture mapping units, and 8 ROPs. The Arc Pro B65 has 2,560 shading units, 160 TMUs, and 80 ROPs. The Pro card also includes 20 ray tracing cores, while the mobile part lists no ray tracing cores at all. Neither GPU lists tensor cores in the database.

Clock behavior also separates the two. The mobile GPU runs at a 300 MHz base clock and boosts to 1800 MHz. The Pro B65 runs at a flat 2400 MHz for both base and boost clocks, with its memory clocked at 2375 MHz (19 Gbps effective). The mobile part's memory clock is listed as "System Shared," again reflecting its reliance on host memory.

The bus interface differs by design intent. The mobile IGP uses a Ring Bus, which integrates directly into the processor package. The Pro B65 uses PCIe 5.0 x16, a high-bandwidth external interface for add-in cards. Display outputs also reflect their roles: the mobile part lists "Portable Device Dependent" outputs, while the Pro card provides 4x DisplayPort 2.1.

The Pro B65's memory subsystem is a dedicated 32 GB GDDR6 pool with 608.0 GB/s bandwidth. The mobile part's memory is "System Dependent" in bandwidth, which means its performance varies with the host laptop's memory configuration. This architectural split explains why the Pro card's compute throughput numbers are so much higher: it has dedicated, high-speed VRAM feeding a much larger shader array.

The TDP gap, 28 W versus 200 W, reflects the fundamental difference in what these chips are designed to do. The mobile part fits into tight thermal envelopes for thin laptops. The Pro card assumes a desktop chassis with active cooling and a 550 W suggested PSU.

The Verdict

The recorded data points to a clear performance hierarchy. The Intel Arc Pro B65 is the dominant compute device in every measured specification category. Its FP32 throughput is roughly 8.9 times higher than the mobile part. Its pixel rate is approximately 13.3 times higher. Its texture rate is roughly 8.9 times higher. Its memory bandwidth is dedicated and enormous at 608.0 GB/s, versus a system-dependent figure for the mobile IGP.

The Arc Graphics 48EU Mobile does hold advantages, but they are not performance advantages. It consumes 28 W versus 200 W. It requires no power connector, no expansion slot, and no separate PSU. It is built for integration into a mobile processor package, not for standalone installation.

The release dates create an additional context gap. The mobile part launched on 2023-12-13, while the Pro B65 has a release date of 2026-03-31. The Pro card is a newer, more advanced design from a later generation (Battlemage versus Meteor Lake). Its Xe2-HPG architecture is a direct successor to the Xe-LPG design in the mobile chip.

For workloads that demand raw graphics and compute throughput, the Arc Pro B65 is the only choice supported by the data. For power-sensitive mobile applications, the Arc Graphics 48EU Mobile is the only integrated option. The database shows no benchmark overlap, no shared test results, and no direct comparison points. Users selecting between these two are choosing between a professional desktop GPU and a mobile integrated solution, not between two comparable alternatives.
