Intel Arc 140V Mobile vs Intel Arc Pro B70 Comparison

The Verdict

The database places both the Intel Arc 140V Mobile and the Intel Arc Pro B70 at the 50th percentile among all GPUs, with no recorded benchmark scores for either part. The Arc 140V Mobile is an integrated processor graphics solution built for thin, portable systems, while the Arc Pro B70 is a dual-slot, 230 W discrete workstation card. The data indicates the Arc Pro B70 is the clear choice for compute-heavy, memory-intensive professional workloads, while the Arc 140V Mobile serves systems where the GPU must share power and thermals with the CPU.

The Arc Pro B70 delivers 22.94 TFLOPS of FP32 throughput, which is 5.7 times the Arc 140V Mobile's 3.994 TFLOPS. It also provides 32 GB of dedicated GDDR6 memory on a 256-bit bus with 608.0 GB/s of bandwidth, whereas the Arc 140V Mobile relies on System Shared memory with bandwidth described as System Dependent. The Arc Pro B70 is the part to select for rendering, simulation, or any task that scales with raw shading power and memory capacity. The Arc 140V Mobile is the part for a compact, low-power platform where a separate graphics card is not an option. The Arc Pro B70 requires a 550 W suggested PSU and an 8-pin power connector, while the Arc 140V Mobile draws its power from the host system as an IGP with a 37 W TDP.

Architecture Differences

The two GPUs share the Xe2 graphics architecture but implement it in different variants. The Arc 140V Mobile uses the Xe2-LPG architecture on Intel's Lunar Lake chip, fabricated on a 3 nm process at TSMC. The Arc Pro B70 uses the Xe2-HPG architecture on the BMG-G31 chip, fabricated on a 5 nm process, also at TSMC. The die sizes reflect the disparity: the Arc 140V Mobile has a 172 mm² die, while the Arc Pro B70 has a 368 mm² die, more than double the area.

The Arc 140V Mobile belongs to the Arc Graphics-M (Lunar Lake) generation, with the predecessor listed as HD Graphics-M. The Arc Pro B70 belongs to the Battlemage (Pro Series) generation. Both parts list the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc Pro B70 includes display outputs of 1x HDMI 2.1a and 3x DisplayPort 2.1, while the Arc 140V Mobile's display outputs are Portable Device Dependent.

The memory architecture is fundamentally different. The Arc 140V Mobile has no dedicated memory; its memory size, type, and bus width are all listed as System Shared, with bandwidth dependent on the system configuration. The Arc Pro B70 has 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s bandwidth and a 2375 MHz memory clock at 19 Gbps effective. The clock behavior also diverges sharply. The Arc 140V Mobile runs at a 300 MHz base clock and 1950 MHz boost. The Arc Pro B70 runs at a 2280 MHz base clock and 2800 MHz boost, meaning the Arc Pro B70's base clock is 1980 MHz higher than the Arc 140V Mobile's base, and its boost is 850 MHz higher.

The power envelope is a defining architectural difference. The Arc 140V Mobile has a 37 W TDP and is mounted as an IGP with no power connectors. The Arc Pro B70 has a 230 W TDP, a dual-slot cooler, a single 8-pin power connector, and a 550 W suggested PSU. The Arc Pro B70 is 267 mm long, 110 mm high, and 39 mm wide; the Arc 140V Mobile has no physical dimensions recorded because it is integrated into a mobile platform.

Head-to-Head Benchmarks

No head-to-head benchmark results are recorded in the database for these two parts. However, the specification data allows direct comparison of theoretical throughput metrics.

The Arc Pro B70's FP32 performance is 22.94 TFLOPS versus 3.994 TFLOPS for the Arc 140V Mobile, a 5.7x advantage. FP16 performance follows the same ratio at 45.88 TFLOPS versus 7.987 TFLOPS, again a 5.7x difference. The pixel rate favors the Arc Pro B70 at 358.4 GPixel/s versus 62.40 GPixel/s, a 5.7x gap. The texture rate is 716.8 GTexel/s versus 124.8 GTexel/s, also a 5.7x gap. These consistent ratios indicate the Arc Pro B70 scales its compute resources uniformly across shading, texturing, and pixel output.

The memory subsystem shows an even larger delta. The Arc Pro B70's 608.0 GB/s bandwidth is not directly comparable to the Arc 140V Mobile's System Dependent figure, but the structural difference is decisive: 32 GB of GDDR6 versus shared system memory with no dedicated pool. The Arc Pro B70 also has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The Arc 140V Mobile has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. That is a 4x advantage for the Arc Pro B70 in every compute unit category.

The Arc 140V Mobile's clock profile is more conservative due to its power limits. Its 1950 MHz boost is 850 MHz lower than the Arc Pro B70's 2800 MHz boost. The Arc Pro B70's 2280 MHz base clock is higher than the Arc 140V Mobile's 1950 MHz boost, meaning the discrete card operates at a higher frequency even at idle base state than the integrated part reaches at maximum boost.

The Arc Pro B70 consumes 193 W more than the Arc 140V Mobile (230 W versus 37 W). That power delta is the cost of the performance advantage, and it explains why the Arc 140V Mobile is constrained to the integrated form factor while the Arc Pro B70 requires a dual-slot cooler and an external power connection.
