Intel Arc 140T Mobile vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either the Intel Arc 140T Mobile or the Intel Arc Pro B70. Both entries have an empty benchmark array, an average benchmark score of zero, and an identical percentile rank of 50 against all GPUs. The head-to-head benchmark table is also empty, with zero recorded wins for either part. Consequently, any performance comparison must be derived from the recorded specification data, not from measured application or game results.

The most decisive specification gap appears in raw compute throughput. The Arc Pro B70 delivers 22.94 TFLOPS of FP32 performance, which is 4.77 times the 4.813 TFLOPS of the Arc 140T Mobile. The same ratio applies to texture and pixel throughput: the B70 reaches 716.8 GTexel/s versus 150.4 GTexel/s, and 358.4 GPixel/s versus 75.20 GPixel/s. These figures indicate that the B70 is roughly 4.8 times faster in peak arithmetic and fill-rate workloads. The FP16 figures follow the same pattern, with the B70 at 45.88 TFLOPS (2:1) against 9.626 TFLOPS (2:1) for the mobile part.

Memory bandwidth shows an even larger relative difference. The B70 has 608.0 GB/s of dedicated GDDR6 bandwidth across a 256-bit bus, while the 140T Mobile uses system shared memory with bandwidth described as system dependent. In practical terms, the B70 has a fixed, high-bandwidth memory path, whereas the 140T Mobile's bandwidth varies with the host platform's memory configuration. The B70 also carries 32 GB of VRAM, while the mobile part has no dedicated memory capacity.

Clock behavior also differs substantially. The B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The 140T Mobile starts at 300 MHz base and boosts to 2350 MHz. The B70's boost clock is 450 MHz higher, and its base clock is much higher than the mobile part's base, reflecting the different power envelopes and cooling requirements. The B70's memory clock is 2375 MHz, or 19 Gbps effective, which is not applicable to the 140T Mobile since its memory is system shared.

The Verdict

The data shows two GPUs with no overlap in intended operating environment. The Intel Arc 140T Mobile is an integrated processor with a 35 W TDP, system shared memory, and no discrete card footprint. The Intel Arc Pro B70 is a dual-slot, 230 W discrete card with 32 GB of GDDR6, a 256-bit bus, and a PCIe 5.0 x16 interface. Every compute metric favors the B70 by a factor of roughly 4.8 to 1 in raw throughput, and memory bandwidth is fixed at 608.0 GB/s versus a system dependent value for the mobile part.

The 140T Mobile is not a competitor to the B70 in absolute performance. Its 4.813 TFLOPS FP32 and 75.20 GPixel/s pixel rate are appropriate for an integrated solution with a 35 W power budget. The B70's 22.94 TFLOPS FP32 and 358.4 GPixel/s pixel rate place it in a different class entirely, with quadruple the shading units, TMUs, ROPs, and RT cores. The B70 also carries 32 GB of dedicated VRAM, which the 140T Mobile cannot match because it relies on shared system memory.

The physical requirements also diverge. The B70 needs a 550 W suggested PSU, one 8-pin connector, and a dual-slot expansion slot with 267 mm of clearance. The 140T Mobile requires none of these, as it is an IGP soldered into a portable device. The B70's release date is later in the database, and its production status is not recorded, while the 140T Mobile is listed as active. The B70 has a recorded launch MSRP of 949 USD, which appears once in this analysis.

Where Each One Wins

The Intel Arc 140T Mobile wins in power efficiency and integration. It operates at 35 W TDP with no external power connector, no slot width, and no PSU requirement. It fits into portable devices where the display outputs are device dependent, meaning the host system determines connectivity. It has the same API support as the B70, including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, which means it can run the same modern graphics workloads at much lower performance levels. Its 300 MHz base clock and 2350 MHz boost clock operate within a 35 W envelope, making it suitable for thin-and-light systems where the B70's 230 W TDP and dual-slot cooler are impossible to accommodate.

The Intel Arc Pro B70 wins in every raw performance category recorded. It has four times the shading units, four times the TMUs, four times the ROPs, and four times the RT cores. Its FP32 throughput of 22.94 TFLOPS is 4.77 times the 140T Mobile's 4.813 TFLOPS. Its FP16 throughput of 45.88 TFLOPS is 4.77 times the 140T Mobile's 9.626 TFLOPS. Texture rate is 716.8 GTexel/s versus 150.4 GTexel/s, and pixel rate is 358.4 GPixel/s versus 75.20 GPixel/s. Memory bandwidth of 608.0 GB/s over a 256-bit bus is a fixed resource, whereas the 140T Mobile's bandwidth is system dependent and shared with the CPU. The B70's 32 GB GDDR6 capacity supports large datasets and high-resolution textures, while the 140T Mobile has no dedicated VRAM.

Clock speeds also favor the B70. Its 2280 MHz base clock is higher than the 140T Mobile's 2350 MHz boost clock, and its 2800 MHz boost clock exceeds the mobile part's boost by 450 MHz. The B70's memory clock of 2375 MHz with 19 Gbps effective speed is a discrete, fixed resource. The B70 also provides a fixed set of display outputs (1x HDMI 2.1a, 3x DisplayPort 2.1), whereas the 140T Mobile's outputs depend on the portable device. The B70 uses a PCIe 5.0 x16 interface, the 140T Mobile uses an IGP bus interface.

For workloads like ray tracing, the B70's 32 RT cores versus 8 RT cores indicates a fourfold advantage in ray tracing hardware. For compute-heavy tasks such as FP32 or FP16 arithmetic, the B70's 22.94 TFLOPS and 45.88 TFLOPS dominate. For memory-bound tasks, the B70's 608.0 GB/s dedicated bandwidth is a clear advantage over a system dependent shared pool. The 140T Mobile's only recorded wins are the lower TDP, the integrated form factor, and the active production status. The B70's production status is null in the database, meaning no active status is recorded.
