Architecture Differences

The Intel Arc Pro B370 uses the Panther Lake chip with the Xe3-LPG architecture, categorized under the Arc Graphics-WM generation. The Intel Arc Pro B70 uses the BMG-G31 chip with the Xe2-HPG architecture, part of the Battlemage Pro Series. This is a fundamental generational split, as the B370’s integrated design targets mobile or compact platforms, while the B70 is a discrete card for workstations.

The process nodes differ significantly. The B370 is built on a 3 nm node at Intel, while the B70 uses a 5 nm node at TSMC. The B70 has a die size of 368 mm², while the B370’s die size is unknown. The B70’s larger, more power-hungry design enables a much higher transistor budget for compute resources.

Compute resources are heavily skewed toward the B70. The B70 has 4096 shading units, 256 texture mapping units, 128 render output units, and 32 ray tracing cores. The B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. This results in a substantial difference in pixel rate: the B70 achieves 358.4 GPixel/s versus 48.00 GPixel/s for the B370. Texture rate is similarly disparate at 716.8 GTexel/s versus 96.00 GTexel/s.

Both products support the same API feature set, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B70’s memory architecture is discrete: 32 GB of GDDR6 on a 256 bit bus with 608.0 GB/s bandwidth. The B370 relies entirely on system shared memory, with bandwidth described as system dependent. The B70’s clock strategy is also different, with a base clock of 2280 MHz and boost of 2800 MHz, whereas the B370 idles at 300 MHz base and boosts to 2400 MHz.

Head-to-Head Benchmarks

The database does not include direct benchmark scores for either product, and the average benchmark score for both is 0. The head-to-head benchmark array is empty, and both products hold a percentile rank of 50 against all GPUs. However, the recorded specification data provides a clear comparison of theoretical peak performance.

In FP32 compute, the B70 delivers 22.94 TFLOPS versus 6.144 TFLOPS for the B370. This means the B70 offers roughly 3.7 times the single-precision floating point throughput. FP16 performance follows the same 2:1 ratio for both: the B70 reaches 45.88 TFLOPS, while the B370 reaches 12.29 TFLOPS.

Memory bandwidth is the largest proportional gap. The B70 provides 608.0 GB/s of dedicated bandwidth, while the B370’s bandwidth is system dependent, meaning it shares the platform’s memory controller. The B70’s 32 GB GDDR6 capacity is fixed and independent of host memory, while the B370’s capacity is whatever the system allocates.

Pixel throughput also heavily favors the B70. At 358.4 GPixel/s, the B70 is about 7.5 times faster than the B370’s 48.00 GPixel/s. Texture fill rate shows a similar pattern: 716.8 GTexel/s versus 96.00 GTexel/s, a ratio of about 7.5 to 1. These ratios reflect the B70’s larger ROP and TMU counts, which are 128 versus 20 and 256 versus 40, respectively.

Clock speeds are interesting because they partially offset the B370’s smaller core count. The B370 boosts to 2400 MHz, which is higher than its 300 MHz base, but the B70 boosts to 2800 MHz. Even with a lower boost clock, the B370 cannot compensate for having roughly one-third the shading units and one-quarter the TMUs. The B70’s advantage in raw throughput is consistent across all measured compute and fill-rate metrics.

The B70’s power envelope is correspondingly larger. The B70 is rated at 230 W TDP and requires a 550 W suggested PSU, while the B370 is rated at 25 W and uses no external power. The B70 is a dual-slot card measuring 267 mm in length, 110 mm in height, and 39 mm in width, with a single 8-pin power connector. The B370 is an IGP with no slot width, no power connectors, and no dimensions, since it is embedded in a portable device.

Where Each One Wins

The Intel Arc Pro B70 wins in every raw performance category recorded in the database. It provides higher FP32 and FP16 throughput, higher pixel and texture fill rates, more shading units, more ray tracing cores, and dedicated high-bandwidth memory. The B70’s 608.0 GB/s bandwidth and 32 GB capacity make it suitable for workloads that require large datasets resident in VRAM, such as rendering, simulation, or machine learning inference. Its 22.94 TFLOPS FP32 performance and 358.4 GPixel/s pixel rate indicate a strong capability for compute-heavy and graphics-intensive tasks.

The B70 also wins on connectivity and expansion. It uses a PCIe 5.0 x16 bus interface, which provides a high-bandwidth link to the host. It has fixed display outputs with HDMI 2.1a and three DisplayPort 2.1 connections, allowing multi-monitor professional setups. The dual-slot design and 8-pin power connector support sustained operation at 230 W.

The Intel Arc Pro B370 wins on power efficiency and physical integration. At 25 W TDP, it consumes a fraction of the B70’s 230 W budget. It requires no power connectors and no suggested PSU, and it is classified as an IGP with no slot width. This makes it suitable for portable devices, thin laptops, or embedded systems where space and thermal limits are strict. The B370’s release date is earlier at 2026-01-26, and its production status is Active, indicating current availability.

The B370 also wins on process node, using a 3 nm node at Intel compared to the B70’s 5 nm node at TSMC. This newer node partially explains how the B370 achieves meaningful compute performance within a 25 W envelope. The B370’s 6.144 TFLOPS FP32 output is still substantial for an integrated solution, and its 2400 MHz boost clock shows that it is not severely clock-limited.

The Verdict

The data indicates two products for entirely different deployment scenarios. The Intel Arc Pro B70 is the clear choice for any workload that demands maximum compute throughput, high memory bandwidth, or large VRAM capacity. Its 22.94 TFLOPS FP32 performance, 608.0 GB/s bandwidth, and 32 GB memory place it in a different class from the B370. The B70’s 358.4 GPixel/s pixel rate and 716.8 GTexel/s texture rate confirm its suitability for heavy rendering tasks. The 230 W TDP and dual-slot cooler are the cost of that performance.

The Intel Arc Pro B370 is the appropriate product for systems where integration and power draw are the primary constraints. Its 25 W TDP, IGP form factor, and system shared memory make it a low-power option for portable or compact platforms. The 3 nm process node gives it a modern foundation, and its 6.144 TFLOPS FP32 output is respectable for an integrated GPU. The B370’s 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate are far below the B70, so it is not a substitute for the discrete card in demanding scenarios.

The benchmark database shows no direct head-to-head results, and both products share a 50th percentile rank against all GPUs, but the specification gap is unambiguous. The B70 offers roughly 3.7 times the FP32 compute and 7.5 times the pixel throughput of the B370. The B70 has 4096 shading units versus 1280, and 32 GB of dedicated GDDR6 versus system shared memory. The B370’s launch date is earlier, and it is marked Active, while the B70’s production status is unlisted. The B70 carries a launch MSRP of 949 USD, while the B370 has no MSRP. Based on the recorded data, the B70 is for professional workloads that need sustained high performance, and the B370 is for low-power integrated systems.
