Intel Arc Graphics 48EU Mobile vs Intel Arc Pro B70 Comparison

Where Each One Wins

The recorded data shows two Intel GPUs built for entirely different roles. The Intel Arc Graphics 48EU Mobile is an integrated graphics processor, while the Intel Arc Pro B70 is a discrete workstation-class card. Their benchmark win totals are equal at zero wins each, simply because no head-to-head benchmark results were recorded in the database. That absence of direct measurements forces an analysis based on architectural and specification differences alone.

The Arc Graphics 48EU Mobile uses the Meteor Lake chip with the Xe-LPG architecture. It belongs to the Arc Graphics-M generation. This is an IGP (integrated graphics processor) with a Ring Bus interface, meaning it shares system memory and its performance scales with the host platform. The data shows a 28 W TDP, which places it firmly in the mobile and low-power segment. Its display outputs are listed as "Portable Device Dependent," confirming its role inside laptops and portable devices.

The Arc Pro B70 uses the BMG-G31 chip with the Xe2-HPG architecture, belonging to the Battlemage Pro Series. This is a dual-slot discrete card with a PCIe 5.0 x16 bus interface. Its TDP is 230 W, and it requires a single 8-pin power connector with a suggested power supply of 550 W. The display outputs are fixed: one HDMI 2.1a and three DisplayPort 2.1 connectors. The physical dimensions are 267 mm in length, 110 mm in height, and 39 mm in width. This is a desktop workstation card, not a mobile part.

The use-case split is clear from the data. The Arc Graphics 48EU Mobile wins on integration and portability, fitting into a system where the CPU and GPU share memory. The Arc Pro B70 wins on raw throughput, memory capacity, and dedicated resources. For workloads that demand sustained rendering, large datasets, or multi-display output, the B70 is the only option that provides the necessary hardware. For thin-and-light systems where power consumption and space are constrained, the 48EU Mobile is the designated solution.

Architecture Differences

The two GPUs come from different Intel architecture families. The Arc Graphics 48EU Mobile uses Xe-LPG, an architecture derived from the Meteor Lake generation. The Arc Pro B70 uses Xe2-HPG, the second-generation Xe architecture found in the Battlemage Pro Series. This architectural gap explains many of the feature and performance differences.

The manufacturing process differs substantially. The 48EU Mobile is built on a 10 nm process at Intel's foundry. The Arc Pro B70 is built on a 5 nm process at TSMC. The die size for the B70 is recorded at 368 mm², while the 48EU Mobile has no die size listed. The transistor count for the B70 is listed as "unknown," and no transistor data exists for the 48EU Mobile either.

The Arc Pro B70 includes 32 ray tracing cores. The Arc Graphics 48EU Mobile has no ray tracing core count listed, indicating that hardware ray tracing is absent or not a featured capability of that integrated part. Neither GPU has tensor cores listed in the database.

The API support differs in one notable way. The Arc Graphics 48EU Mobile supports DirectX 12 (12_1). The Arc Pro B70 supports DirectX 12 Ultimate (12_2), which includes additional features such as ray tracing and mesh shaders. Both GPUs support OpenGL 4.6 and Vulkan 1.4.

The memory architecture is fundamentally different. The 48EU Mobile uses System Shared memory, with its memory type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." The Arc Pro B70 has dedicated 32 GB of GDDR6 memory on a 256-bit bus, delivering 608.0 GB/s of bandwidth. This is the largest single architectural difference between the two parts.

Head-to-Head Benchmarks

No head-to-head benchmark results are recorded in the database. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. Direct numerical comparison of performance is therefore not possible from the recorded data.

What the data does provide are the raw compute specifications. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 performance and 45.88 TFLOPS of FP16 performance (2:1 ratio). The Arc Graphics 48EU Mobile delivers 1,382.4 GFLOPS of FP32 performance, which converts to 1.38 TFLOPS, and 2.765 TFLOPS of FP16 performance (2:1 ratio). The B70 is roughly 16.6 times faster in FP32 and FP16 based on these figures. Both numbers come directly from the database.

The pixel rate and texture rate tell a similar story. The Arc Pro B70 achieves 358.4 GPixel/s and 716.8 GTexel/s. The Arc Graphics 48EU Mobile achieves 14.40 GPixel/s and 43.20 GTexel/s. The B70 leads by a factor of about 24.9 in pixel throughput and 16.6 in texture throughput.

Clock speeds also favor the discrete card. The Arc Pro B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The Arc Graphics 48EU Mobile has a base clock of 300 MHz and a boost clock of 1800 MHz. The B70's boost clock is 1000 MHz higher than the integrated part's boost clock.

Memory bandwidth is the most extreme difference. The B70 provides 608.0 GB/s of dedicated bandwidth. The 48EU Mobile's bandwidth is "System Dependent," meaning it varies with the host system's memory configuration. The B70's memory clock is listed at 2375 MHz with 19 Gbps effective speed, while the 48EU Mobile's memory clock is "System Shared."

The Verdict

The data indicates two GPUs with no overlapping use cases. The Intel Arc Graphics 48EU Mobile is an integrated part for mobile systems, with a 28 W TDP, shared system memory, and a Ring Bus interface. Its performance figures are modest: 1,382.4 GFLOPS FP32, 14.40 GPixel/s pixel rate, and 43.20 GTexel/s texture rate. The boost clock reaches 1800 MHz, and the architecture is Xe-LPG on a 10 nm process. This part suits portable devices where low power consumption and integration are priorities.

The Intel Arc Pro B70 is a discrete workstation card with 230 W TDP, 32 GB of dedicated GDDR6 memory, and 608.0 GB/s bandwidth. It delivers 22.94 TFLOPS FP32, 358.4 GPixel/s pixel rate, and 716.8 GTexel/s texture rate. The boost clock reaches 2800 MHz, the architecture is Xe2-HPG on a 5 nm process at TSMC, and it includes 32 ray tracing cores. The dual-slot card measures 267 mm by 110 mm by 39 mm and requires a 550 W power supply. Its launch MSRP is 949 USD.

The database records no head-to-head benchmarks, so the verdict rests on specification analysis. The Arc Pro B70 is the choice for compute-heavy workloads, large memory footprints, and multi-display workstation setups. The Arc Graphics 48EU Mobile is the choice for integrated mobile graphics where the host system provides shared memory and the thermal envelope is limited to 28 W. The architectural generation gap, Xe-LPG versus Xe2-HPG, and the process node difference, 10 nm versus 5 nm, reinforce that these are products from different market segments and different design generations. The production status of the 48EU Mobile is Active, while the B70 has no production status listed, but the release dates confirm the B70 is a newer product by roughly two years and three months.
