Intel Arc Pro B50 vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The Intel Arc Pro B50 and Intel Arc Pro B70 share the same Xe2-HPG architecture and Battlemage (Pro Series) generation, but the benchmark data for the two cards is strikingly uneven. The B50 has a full suite of recorded measurements across eight tests, while the B70 has no recorded benchmark scores in the database at all. This makes a direct per-test comparison impossible, so the analysis must instead rely on the B50's absolute scores, its percentile placement, and the architectural specifications that define the B70's expected performance envelope.

The B50's strongest recorded result is in PassMark G3D, where it scores 12,553. This is a compute-oriented measurement that includes DirectX 9, 10, 11, and 12 workloads, and it places the card at the 17th percentile among all GPUs in the database. In the same suite, the B50 records a PassMark GPU Compute score of 6,037, which reflects general-purpose compute throughput rather than graphics rendering. The 3DMark Steel Nomad DX12 test yields 1,604 points, a modern DirectX 12 workload that stresses ray tracing and rasterization together. The DirectX-specific PassMark results show 144 for DirectX 9, 100 for DirectX 11, 64 for DirectX 12, and 58 for DirectX 10. The 2D graphics score is 717.

The B50's average benchmark score across all recorded tests is 2,660. Its nearest rivals in the database are all NVIDIA cards, and the deltas are extremely small. The GeForce GT 1030 averages 2,662, a difference of -0.1 percent relative to the B50. The Quadro K1100M averages 2,664, a -0.2 percent delta. The GeForce GT 440 averages 2,645, which puts the B50 ahead by 0.6 percent. The GeForce RTX 5070 SUPER averages 2,690, meaning the B50 trails by 1.1 percent. These margins are within noise for most workloads, and the B50 effectively sits in a cluster of cards with near-identical average scores. The RTX 5070 SUPER is a modern high-end part, yet its average score is only 1.1 percent above the B50's, which indicates that the average metric is dominated by a mix of tests that do not heavily favor either architecture.

The B70 has no benchmark entries, no wins, and an average score of zero. Its percentile is listed as 50, which is a placeholder that cannot be interpreted as a measured result. The head-to-head benchmark array is empty, and the wins count for both cards is zero. The only meaningful comparison available is structural: the B70's specifications suggest a substantially larger silicon, but the database contains no recorded data to confirm how that translates into actual scores.

The Verdict

The data supports only one clear conclusion: the Intel Arc Pro B50 is a fully measured product, while the Intel Arc Pro B70 is not. The B50's average benchmark score of 2,660 places it at the 17th percentile, and its nearest rivals are all within a 1.1 percent band. The B70's lack of any recorded scores means the database has no evidence of its performance, and any assertion about its speed would be speculation.

For users who require verified performance data, the B50 is the only card in this pair with a measurement history. Its scores indicate a modest graphics solution that trades blows with low-end NVIDIA parts from different eras. The B70, by contrast, is a specification sheet without a benchmark record. Its 50th percentile placeholder is not backed by any test result, and the average score of zero confirms that no measurements have been ingested.

The choice between the two is therefore not a performance decision but a data availability decision. The B50 offers a complete picture: 16 GB of GDDR6 memory, a 128-bit bus, 224.0 GB/s of bandwidth, and 2,048 shading units. The B70 offers 32 GB of GDDR6 memory, a 256-bit bus, 608.0 GB/s of bandwidth, and 4,096 shading units, but none of that hardware has been exercised in the database. The B50's 17th percentile ranking against all GPUs is the only measured percentile in this comparison, and it is low. The B70's 50th percentile is an unverified entry.

Architecture Differences

Both cards use the Xe2-HPG architecture from Intel's Battlemage (Pro Series) generation, fabricated by TSMC on a 5 nm process. The foundational design is identical, but the physical implementation diverges sharply. The B50 uses the BMG-G21 chip with a die size of 272 mm² and a transistor count of 19,600 million, yielding a density of 72.1 million transistors per square millimeter. The B70 uses the BMG-G31 chip with a die size of 368 mm², but its transistor count is listed as unknown, and its density is not recorded.

The B70's die is 96 mm² larger than the B50's, a 35.3 percent increase in silicon area. The B50's transistor count is known, but the B70's is not, so the density comparison cannot be completed. The B70 doubles the shading units from 2,048 to 4,096, doubles the texture mapping units from 128 to 256, and multiplies the render output units from 16 to 128. The B70 also doubles the ray tracing cores from 16 to 32. Neither card has tensor cores listed.

The memory subsystem differs in width and capacity. The B50 runs a 128-bit bus, and the B70 runs a 256-bit bus, exactly double the width. The B50's memory clock is 1750 MHz with 14 Gbps effective, while the B70's is 2375 MHz with 19 Gbps effective. The bandwidth scales from 224.0 GB/s on the B50 to 608.0 GB/s on the B70, a 2.7 times increase. The B70's pixel rate is 358.4 GPixel/s versus 41.60 GPixel/s on the B50, and the texture rate is 716.8 GTexel/s versus 332.8 GTexel/s. The FP32 throughput is 22.94 TFLOPS on the B70 and 10.65 TFLOPS on the B50, and FP16 is 45.88 TFLOPS versus 21.30 TFLOPS.

The B70 has a PCIe 5.0 x16 interface, while the B50 uses PCIe 5.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The display outputs differ: the B50 has four mini-DisplayPort 2.1 connectors, and the B70 has one HDMI 2.1a plus three DisplayPort 2.1 connectors.

Specification Differences

The clock speeds are the first clear divergence. The B50 has a base clock of 1700 MHz and a boost clock of 2600 MHz. The B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The B70's base clock is 580 MHz higher, and its boost clock is 200 MHz higher. The memory clock on the B50 is 1750 MHz with 14 Gbps effective, while the B70 runs at 2375 MHz with 19 Gbps effective.

Memory capacity doubles from 16 GB to 32 GB, and the bus width doubles from 128 bit to 256 bit. The bandwidth jumps from 224.0 GB/s to 608.0 GB/s. The shading units double from 2,048 to 4,096, the TMUs double from 128 to 256, and the ROPs increase from 16 to 128. The ray tracing cores double from 16 to 32. The FP32 compute nearly doubles from 10.65 TFLOPS to 22.94 TFLOPS, and FP16 doubles from 21.30 to 45.88 TFLOPS.

The power requirements are substantially different. The B50 has a TDP of 70 W, no power connectors, and a suggested PSU of 250 W. The B70 has a TDP of 230 W, one 8-pin power connector, and a suggested PSU of 550 W. The physical dimensions also differ: the B50 is 167 mm long, 69 mm tall, and 40 mm wide, while the B70 is 267 mm long, 110 mm tall, and 39 mm wide. Both are dual-slot cards. The B50 is listed as Active in production status, while the B70 has no production status recorded. The B50's release date is September 4, 2025, and the B70's is March 25, 2026. The B50 has a launch MSRP of 349 USD, and the B70 has a launch MSRP of 949 USD.

Where Each One Wins

The Intel Arc Pro B50 wins in the only category where actual measurements exist. Its eight recorded benchmark scores provide a complete picture of a card that sits at the 17th percentile among all GPUs. Its average score of 2,660 is competitive with the GeForce GT 1030, the Quadro K1100M, the GeForce GT 440, and the GeForce RTX 5070 SUPER, all within a 1.1 percent band. The B50's 16 GB memory capacity and 224.0 GB/s bandwidth are sufficient for its measured performance level. Its 70 W TDP and absence of power connectors mean it can run in systems with a suggested 250 W PSU, and its 167 mm length fits in compact chassis. The B50 is also the only card in this pair with a production status of Active.

The Intel Arc Pro B70 wins in every specification category that does not require a benchmark result. It offers double the memory capacity at 32 GB, more than double the bandwidth at 608.0 GB/s, double the shading units at 4,096, double the ray tracing cores at 32, and a much larger die at 368 mm². Its FP32 throughput of 22.94 TFLOPS is more than double the B50's 10.65 TFLOPS. The B70's pixel rate of 358.4 GPixel/s is more than eight times the B50's 41.60 GPixel/s, and its texture rate of 716.8 GTexel/s is more than double the B50's 332.8 GTexel/s. The B70 also has a wider PCIe 5.0 x16 interface versus the B50's x8, and it includes an HDMI 2.1a output alongside three DisplayPort 2.1 connectors, while the B50 only offers mini-DisplayPort 2.1.

The B70's 50th percentile ranking is listed in the database, but with no benchmark scores to support it, that figure cannot be treated as a measured outcome. The B50's 17th percentile is backed by data. For use cases that depend on verified performance, the B50 is the only choice. For use cases that prioritize hardware specifications such as memory capacity, bandwidth, and compute throughput, the B70's specifications indicate a more capable part, but its performance remains unrecorded. The B70's 230 W TDP, one 8-pin power connector, and 550 W suggested PSU indicate a much higher power draw, and its 267 mm length requires a larger case. The B70's launch MSRP of 949 USD is the only price data available, and the B50's launch MSRP of 349 USD is the corresponding figure for the smaller card.
