Intel Arc Pro B70 vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc Pro B70 and the NVIDIA RTX PRO 4000 Blackwell. The Intel Arc Pro B70 has no recorded benchmark scores, average score, or nearest rivals in the database, while the NVIDIA RTX PRO 4000 Blackwell has a complete benchmark profile. This asymmetry limits direct comparison, but the available data for the RTX PRO 4000 Blackwell, combined with the architectural specifications of both cards, provides a basis for analysis.

The NVIDIA RTX PRO 4000 Blackwell records an average benchmark score of 27135, placing it at the 72nd percentile among all GPUs in the database. Its nearest rivals include the AMD Radeon RX 6700 XT with an average score of 27425, which is 1.1% higher, and the NVIDIA GeForce RTX 4070 Mobile with an average score of 27435, also 1.1% higher. The NVIDIA GeForce RTX 3090 scores 27565, 1.6% higher, while the NVIDIA RTX A4000 scores 26683, which is 1.7% lower than the RTX PRO 4000 Blackwell. These deltas indicate the RTX PRO 4000 Blackwell sits within a tight performance cluster, trailing its closest rivals by roughly one to two percent while leading the RTX A4000 by nearly two percent.

The individual benchmark scores for the RTX PRO 4000 Blackwell show notable variance across test types. In 3DMark Steel Nomad DX12, it scores 4648. The Geekbench Vulkan result is 194168, a strong showing for compute-oriented workloads. PassMark results include a G3D score of 28427 and a GPU compute score of 14805. The DirectX 9, 10, 11, and 12 scores are 354, 173, 276, and 97, respectively, while the G2D score is 1265. The wide spread between the G3D score and the per-API DirectX scores suggests the card's performance is highly workload-dependent, with modern API tests presenting different demands than legacy ones.

Because the Intel Arc Pro B70 lacks benchmark entries, its wins column is zero, and the head-to-head wins for the NVIDIA card are also zero in the recorded data. The absence of measured results for the Intel card means no direct performance verdict can be issued from benchmark comparisons alone. The data instead points to the RTX PRO 4000 Blackwell as the only card with empirical scores, and the Intel card's capabilities must be evaluated through its specification sheet rather than measured outcomes.

Architecture Differences

The two GPUs diverge fundamentally in architecture, chip design, and feature set. The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. The NVIDIA RTX PRO 4000 Blackwell uses the GB203 chip with Blackwell 2.0 architecture, from the Blackwell PRO W (x000) generation. Both are fabricated by TSMC on a 5 nm process, but the similarity ends there.

The Intel chip has a die size of 368 mm², while the NVIDIA chip measures 378 mm². NVIDIA reports 45,600 million transistors and a transistor density of 120.6 million per mm². The Intel datasheet lists transistor count as unknown, so density cannot be computed from the recorded data. This difference in transparency aside, the NVIDIA chip packs more transistors into a slightly larger die, which correlates with its higher shader count.

The Intel Arc Pro B70 carries 4096 shading units, 256 texture mapping units, and 128 raster operation units. It has 32 ray tracing cores and no tensor cores listed. The NVIDIA RTX PRO 4000 Blackwell has 8960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The NVIDIA card has more than double the shading units and RT cores, and it includes tensor cores that the Intel card lacks entirely. The ROP count favors Intel, 128 versus 96, which affects pixel throughput.

Clock behavior also differs sharply. The Intel card has a base clock of 2280 MHz and a boost clock of 2800 MHz. The NVIDIA card has a base clock of 1230 MHz and a boost clock of 2055 MHz. Despite the lower clocks, the NVIDIA card's higher shader count yields a higher FP32 rating of 36.83 TFLOPS, while the Intel card delivers 22.94 TFLOPS. The FP16 figures show a strategic difference: Intel achieves 45.88 TFLOPS at a 2:1 ratio, while NVIDIA matches its FP32 at 36.83 TFLOPS with a 1:1 ratio. This indicates Intel uses a shader-based approach for FP16, while NVIDIA treats it as a direct throughput extension.

Memory architecture is another major split. The Intel card uses 32 GB of GDDR6 on a 256-bit bus, achieving 608.0 GB/s bandwidth. The NVIDIA card uses 24 GB of GDDR7 on a 192-bit bus, achieving 672.0 GB/s. The NVIDIA card has a narrower bus but higher memory bandwidth due to the faster GDDR7 standard. Memory clocks reflect this: Intel runs at 2375 MHz (19 Gbps effective), while NVIDIA runs at 1750 MHz (28 Gbps effective). The Intel card's larger capacity may benefit large dataset workloads, but the NVIDIA card moves data faster.

Pixel and texture rates further differentiate the pair. The Intel card achieves 358.4 GPixel/s and 716.8 GTexel/s. The NVIDIA card achieves 197.3 GPixel/s and 575.4 GTexel/s. The Intel card leads in both rates, driven by its higher ROP count and clock speeds. This suggests the Intel card has an advantage in fill-rate-bound scenarios, while the NVIDIA card's advantage lies in compute and ray tracing throughput.

Both cards support PCIe 5.0 x16 and share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the Intel card offering 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card offers 4x DisplayPort 2.1b. Power and physical design also contrast: the Intel card has a 230 W TDP, a dual-slot width, a 1x 8-pin connector, and a suggested PSU of 550 W. The NVIDIA card has a 140 W TDP, a single-slot width, a 1x 16-pin connector, and a suggested PSU of 300 W. The NVIDIA card is more power-efficient and physically slimmer.

Where Each One Wins

The NVIDIA RTX PRO 4000 Blackwell wins decisively in compute-oriented workloads. Its FP32 throughput of 36.83 TFLOPS is substantially higher than the Intel card's 22.94 TFLOPS. With 8960 shading units, 70 RT cores, and 280 tensor cores, the NVIDIA card is positioned for ray tracing and AI-adjacent tasks. Its 1:1 FP16 ratio means it does not artificially inflate FP16 throughput, making its FP32 and FP16 figures identical, which is useful for workloads that rely on consistent precision across formats. The NVIDIA card also holds a memory bandwidth advantage at 672.0 GB/s versus 608.0 GB/s, despite a narrower 192-bit bus, thanks to GDDR7 memory.

The NVIDIA card also wins on efficiency and physical integration. Its 140 W TDP is far lower than the Intel card's 230 W, and its suggested PSU of 300 W versus 550 W reflects that. The single-slot design at 20 mm width is much slimmer than the Intel card's 39 mm dual-slot profile. The NVIDIA card is also shorter at 241 mm versus 267 mm. These factors make it easier to install in space-constrained workstations. Its production status is listed as active, while the Intel card has no production status recorded.

The Intel Arc Pro B70 wins in specific throughput metrics that favor fill-rate and memory capacity. Its pixel rate of 358.4 GPixel/s is nearly double the NVIDIA card's 197.3 GPixel/s. Its texture rate of 716.8 GTexel/s also exceeds the NVIDIA card's 575.4 GTexel/s. These advantages, driven by higher clocks and more ROPs, suggest the Intel card is better suited for rasterization-heavy tasks that depend on pixel and texture throughput rather than shader compute.

The Intel card also offers more memory capacity at 32 GB versus 24 GB, which could benefit workloads with large working sets that fit within VRAM. Its FP16 throughput of 45.88 TFLOPS is higher than the NVIDIA card's 36.83 TFLOPS, and the 2:1 ratio indicates the Intel card can double its FP16 rate when the workload allows. The Intel card has a longer PCIe slot footprint but supports the same PCIe 5.0 x16 interface. Its display output includes an HDMI 2.1a port, while the NVIDIA card relies exclusively on DisplayPort 2.1b.

The recorded benchmark data only covers the NVIDIA card, and it shows a 72nd percentile ranking with an average score of 27135. The nearest rivals, including the AMD Radeon RX 6700 XT and NVIDIA GeForce RTX 4070 Mobile, sit within 1.1% of its score, indicating the RTX PRO 4000 Blackwell is competitive but not dominant within its peer group. The Intel card has no recorded benchmark scores, so its real-world performance cannot be quantified from the database. The architectural data suggests a split: Intel leads in fill-rate and memory capacity, NVIDIA leads in compute throughput, ray tracing, tensor performance, bandwidth, and power efficiency.
