Intel Arc B580 vs Intel Arc Pro B70 Comparison

Intel Arc B580 and Intel Arc Pro B70 are two distinct implementations of Intel’s Xe2-HPG architecture, separated by their target roles and physical design. The B580, part of the Battlemage Arc 5 generation, is a consumer-focused card, while the Pro B70, from the Battlemage Pro Series, is built for professional workloads. The database contains no direct head-to-head benchmark scores between the two, but the available measurements for the B580 and the recorded specifications for the Pro B70 allow for a structured comparison. The most striking difference is the performance tier: the B580’s average benchmark score across all recorded tests is 23021, while the Pro B70 has no recorded benchmark scores, leaving its real-world performance unquantified in the database. The B580 sits at the 68th percentile among all GPUs, with nearest rivals including the AMD Radeon RX 580 2048SP (average score 23061, delta 0.2% higher) and the NVIDIA GeForce RTX 3080 (average score 23172, delta 0.7% higher). The Pro B70 holds a 50th percentile rating, but that figure is based on no actual measurements, making it a placeholder rather than a tested result.

Head-to-Head Benchmarks

Without any head-to-head benchmark entries in the database, the comparison rests on the B580’s ten recorded test scores and the Pro B70’s empty benchmark array. For the B580, the strongest result appears in 3DMark Steel Nomad DX12, where it scores 3068 points. This is a modern DirectX 12 workload, and the score places the card in a competitive position relative to its nearest rivals, though the database does not list a direct comparison for this specific test. In Geekbench OpenCL, the B580 records 92821 points, and in Geekbench Vulkan it reaches 109672 points, showing a slightly higher compute performance under Vulkan than OpenCL. PassMark results show a mixed profile: DirectX 9 scores 183, DirectX 10 scores 76, DirectX 11 scores 128, and DirectX 12 scores 76. The G2D score is 709, while the G3D score is 15748, and GPU compute is 7729. These numbers indicate that the B580 is strongest in older DirectX 9 and modern G3D workloads, but weaker in DirectX 10 and 12 passmark subtests.

The Pro B70 has no scores, so the database cannot confirm any win for either card in a direct comparison. The B580’s average score of 23021, when placed against its nearest rivals, shows it is nearly identical to the RX 580 2048SP (delta 0.2% lower) and the RTX 2080 (delta 0.6% higher), while it trails the RTX 3080 by 0.7% and the P106-100 by 1%. This suggests the B580 performs at a level consistent with high-end previous-generation cards, but the Pro B70’s larger die and higher theoretical compute (22.94 TFLOPS FP32 versus 13.67 TFLOPS) indicate it should outperform the B580 if those specifications translate into real scores. The database, however, does not provide evidence of that, so no definitive win can be assigned to either card in a benchmark-based head-to-head.

Architecture Differences

Both cards share the Xe2-HPG architecture and are fabricated on a 5 nm process at TSMC, but they use different chips. The B580 is built on the BMG-G21 die, which measures 272 mm² and contains 19,600 million transistors, yielding a transistor density of 72.1 million per mm². The Pro B70 uses the BMG-G31 die, which is larger at 368 mm², with transistor count listed as unknown and no density figure. The larger die on the Pro B70 directly corresponds to a more substantial hardware configuration: it has 4096 shading units, 256 texture mapping units, and 128 raster output units, compared to the B580’s 2560 shading units, 160 TMUs, and 80 ROPs. The ray tracing cores also scale up, with the Pro B70 featuring 32 RT cores versus the B580’s 20.

Clock speeds differ in a nuanced way. The B580 runs at a fixed base and boost clock of 2670 MHz, meaning no dynamic boost range. The Pro B70 has a lower base clock of 2280 MHz but a higher boost clock of 2800 MHz, indicating a wider frequency range under load. Memory clocks are identical at 2375 MHz, translating to 19 Gbps effective, but the memory subsystem differs substantially. The B580 uses 12 GB of GDDR6 on a 192-bit bus, yielding 456.0 GB/s of bandwidth. The Pro B70 doubles capacity to 32 GB, widens the bus to 256 bit, and increases bandwidth to 608.0 GB/s. The interface also changes: the B580 uses PCIe 4.0 x8, while the Pro B70 uses PCIe 5.0 x16, offering more host bandwidth for data transfer. Display outputs are the same on both: 1x HDMI 2.1a and 3x DisplayPort 2.1. API support is identical, with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The power delivery differs only in suggested PSU and TDP: the B580 has a 190 W TDP and requires a 450 W PSU, while the Pro B70 has a 230 W TDP and needs a 550 W PSU. Both use a single 8-pin power connector and are dual-slot cards.

Where Each One Wins

Based on the recorded data, the B580 wins in the only area where actual measurements exist: benchmark scores. It has a complete set of results, and its average score of 23021 places it in the 68th percentile of all GPUs. The Pro B70, with no benchmark data, cannot claim any recorded performance win. However, the specification sheet gives the Pro B70 clear theoretical advantages. Its FP32 compute of 22.94 TFLOPS is 67.8% higher than the B580’s 13.67 TFLOPS, and its FP16 performance of 45.88 TFLOPS (2:1) doubles the B580’s 27.34 TFLOPS. The Pro B70 also has higher pixel rate (358.4 GPixel/s versus 213.6 GPixel/s) and texture rate (716.8 GTexel/s versus 427.2 GTexel/s), indicating faster rasterization and texture processing. Memory capacity is the most decisive split: 32 GB versus 12 GB, with the Pro B70 also offering 33.3% more bandwidth (608.0 GB/s versus 456.0 GB/s). For workloads that require large datasets or high-resolution textures, the Pro B70’s memory advantage is substantial. For scenarios where clock speed matters more than core count, the B580’s fixed 2670 MHz boost is actually higher than the Pro B70’s base clock of 2280 MHz, though the Pro B70 can boost to 2800 MHz. The B580 also has a smaller die, which may imply lower manufacturing complexity, but the database does not include power efficiency measurements.

The Verdict

The database presents a clear split between verified performance and theoretical capability. The Intel Arc B580 is the only card with actual benchmark results, and those results show it performing at a level comparable to the NVIDIA GeForce RTX 3080, with a delta of only 0.7% lower in average score. Its 68th percentile ranking and complete test suite make it a known quantity for gaming and general compute. The Intel Arc Pro B70, by contrast, has no recorded benchmarks, so its 50th percentile is an empty placeholder. However, its specifications indicate a far more powerful hardware configuration: 60% more shading units, 60% more TMUs, 60% more ROPs, 60% more RT cores, and 68% higher FP32 compute. The memory advantage is even more pronounced, with 32 GB versus 12 GB and 608.0 GB/s versus 456.0 GB/s. For users who require large framebuffers or high-bandwidth data movement, the Pro B70’s design clearly targets that use case. The B580 wins on clock stability, with a flat 2670 MHz boost, and on measured performance. The Pro B70 wins on raw throughput, memory capacity, and a newer PCIe 5.0 x16 interface. The verdict from the data is that the B580 is the validated performer, while the Pro B70 is an unproven but specification-superior card. The choice depends on whether one trusts recorded scores or projected specifications, and the database currently supports the former for the B580 and only the latter for the Pro B70.
