Intel Arc Graphics 2 Xe Mobile vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the Intel Arc Graphics 2 Xe Mobile and the Intel Arc Pro B70. The wins tally for each part is zero, and the average benchmark score for both entries is zero. This absence of measured data means any comparative performance analysis must be derived strictly from the architectural and specification differences documented in the database, not from observed frame rates or compute scores.

Both GPUs share the same percentile placement at 50.0 against all GPUs in the database, which indicates that without benchmark data, the database assigns them a median standing. The Intel Arc Graphics 2 Xe Mobile reports an FP32 throughput of 1,280.0 GFLOPS, while the Intel Arc Pro B70 reports 22.94 TFLOPS. The Pro B70 therefore delivers roughly 18 times the raw single-precision compute throughput on paper. Similarly, the pixel rate for the mobile part is 20.00 GPixel/s versus 358.4 GPixel/s for the Pro B70, a 17.9x difference. Texture rate shows 40.00 GTexel/s versus 716.8 GTexel/s, an 17.9x gap as well.

The memory subsystem amplifies the divide. The Arc Graphics 2 Xe Mobile uses system shared memory with system dependent bandwidth, while the Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus delivering 608.0 GB/s. The mobile part has no dedicated memory bandwidth figure in the database, only "System Dependent", so no numerical comparison is possible for bandwidth. Clock behavior also differs: the mobile GPU runs a 300 MHz base and 2500 MHz boost, while the Pro B70 runs a 2280 MHz base and 2800 MHz boost. The boost advantage for the Pro B70 is 300 MHz, and its base clock is 1980 MHz higher.

Ray tracing resources show a 16x difference in RT core count: 2 RT cores for the mobile part versus 32 for the Pro B70. Shading units number 256 versus 4096, a 16x difference. Texture mapping units are 16 versus 256, also 16x. Render output units are 8 versus 128, a 16x difference. These consistent 16x ratios across shading, texturing, and rasterization suggest the Pro B70 is architecturally scaled to a much larger execution footprint, which aligns with its higher power envelope and physical size.

The only specification where the mobile part leads is process node: 3 nm versus 5 nm. This does not translate into measured performance without benchmark data, but it indicates the mobile GPU uses a denser manufacturing process. The database records no benchmark results, so the head-to-head section must conclude that no empirical wins exist to report. The theoretical compute and memory advantages belong entirely to the Arc Pro B70 based on the recorded specifications.

FAQ

Q: Which GPU has higher FP32 compute throughput?

A: The Intel Arc Pro B70 records 22.94 TFLOPS of FP32 compute, while the Intel Arc Graphics 2 Xe Mobile records 1,280.0 GFLOPS. The Pro B70 offers roughly 18 times the single-precision throughput.

Q: How do the memory configurations differ?

A: The Arc Pro B70 uses 32 GB of GDDR6 memory on a 256-bit bus with 608.0 GB/s bandwidth. The Arc Graphics 2 Xe Mobile uses system shared memory with system dependent bandwidth, meaning it draws on the host system's memory rather than dedicated VRAM.

Q: What is the difference in ray tracing capability?

A: The Arc Pro B70 has 32 ray tracing cores, while the Arc Graphics 2 Xe Mobile has 2 ray tracing cores. This is a 16x difference in RT core count.

Q: Which GPU uses a smaller manufacturing process?

A: The Intel Arc Graphics 2 Xe Mobile uses a 3 nm process fabricated by Intel, while the Intel Arc Pro B70 uses a 5 nm process fabricated by TSMC. The mobile part uses the smaller node.

Q: What are the boost clock speeds for each GPU?

A: The Arc Graphics 2 Xe Mobile boosts to 2500 MHz from a 300 MHz base. The Arc Pro B70 boosts to 2800 MHz from a 2280 MHz base. The Pro B70 has a 300 MHz higher boost clock.

Q: Are there any benchmark scores recorded for either GPU?

A: No. The database lists zero benchmark results for both GPUs, and the average benchmark score for each is zero. The head-to-head benchmark array is empty, and both parts hold a 50th percentile placement against all GPUs.

Architecture Differences

The two GPUs implement different Intel architectures. The Intel Arc Graphics 2 Xe Mobile uses the Xe3-LPG architecture on the Wildcat Lake chip, belonging to the Arc Graphics-M (Wildcat Lake) generation. The Intel Arc Pro B70 uses the Xe2-HPG architecture on the BMG-G31 chip, belonging to the Battlemage (Pro Series) generation. These are separate architectural families: LPG typically targets low-power graphics, while HPG targets high-performance graphics. The mobile part uses a 3 nm process at Intel's foundry, while the Pro B70 uses a 5 nm process at TSMC. Die size is recorded only for the Pro B70 at 368 mm²; the mobile part's die size is listed as unknown.

Execution resources scale dramatically between the two. The mobile GPU has 256 shading units, 16 texture mapping units, 8 render output units, and 2 ray tracing cores. The Pro B70 has 4096 shading units, 256 texture mapping units, 128 render output units, and 32 ray tracing cores. Each of these four resource categories is exactly 16 times larger on the Pro B70. The FP16 compute rates follow the same pattern: the mobile part records 2.560 TFLOPS (2:1), while the Pro B70 records 45.88 TFLOPS (2:1), an 17.9x difference that mirrors the FP32 ratio.

Memory architecture differs fundamentally. The mobile GPU uses system shared memory with no dedicated VRAM, no dedicated bus width, and bandwidth that depends on the host system. The Pro B70 uses 32 GB of GDDR6 on a 256-bit bus with a fixed 608.0 GB/s bandwidth. The Pro B70 memory clock is recorded as 2375 MHz with 19 Gbps effective data rate, while the mobile part's memory clock is listed as "System Shared" with no frequency. The Pro B70 connects via PCIe 5.0 x16, while the mobile part uses an IGP bus interface. Display outputs also differ: the mobile GPU is "Portable Device Dependent", while the Pro B70 has 1x HDMI 2.1a and 3x DisplayPort 2.1.

Power and physical characteristics separate the parts further. The mobile GPU has a 25 W TDP, is an IGP slot width, uses no power connectors, and has no suggested PSU. The Pro B70 has a 230 W TDP, is a dual-slot card, uses a 1x 8-pin power connector, and has a suggested PSU of 550 W. The Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width. The mobile part has no recorded dimensions. The API support is identical for both: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status for the mobile part is Active, while the Pro B70 has no recorded production status. The mobile part lists HD Graphics-M as its predecessor, while the Pro B70 has no predecessor recorded.

The Verdict

Based strictly on the recorded specifications, the Intel Arc Pro B70 is the substantially more capable part in every measured compute and memory dimension. Its FP32 throughput of 22.94 TFLOPS dwarfs the 1,280.0 GFLOPS of the mobile GPU. Its 32 GB GDDR6 memory with 608.0 GB/s bandwidth provides dedicated high-speed storage, whereas the mobile GPU relies on system shared memory with no fixed bandwidth. The Pro B70's 32 RT cores, 4096 shading units, 256 TMUs, and 128 ROPs each represent a 16x resource advantage over the mobile GPU. Its 2800 MHz boost clock exceeds the mobile part's 2500 MHz boost, and its 2280 MHz base clock is 1980 MHz higher than the 300 MHz base of the mobile GPU.

The Intel Arc Graphics 2 Xe Mobile holds advantages only in process node (3 nm versus 5 nm), power draw (25 W versus 230 W), and physical integration (IGP versus dual-slot card). It is designed for portable devices with system dependent display outputs and no dedicated power connectors. The Pro B70 is designed for discrete installation with a dual-slot form factor, 1x 8-pin power, and a 550 W suggested PSU. The launch MSRP for the Pro B70 is 949 USD. The mobile part has no recorded launch MSRP.

The data indicates that users requiring dedicated VRAM, high compute throughput, and substantial ray tracing resources should select the Intel Arc Pro B70. Users constrained to integrated graphics within a portable device, where power consumption must stay at 25 W and no discrete card can be installed, should select the Intel Arc Graphics 2 Xe Mobile. The Pro B70 is not a substitute for an IGP solution, and the mobile GPU cannot approach the Pro B70's recorded compute or memory specifications. The absence of benchmark data means no real-world performance validation exists in the database, so these conclusions rest entirely on the recorded technical specifications.
