The Verdict

The benchmark database shows a clear performance hierarchy: the NVIDIA RTX PRO 5000 72 GB Blackwell is the substantially faster card in raw compute and rasterization workloads. Its recorded PassMark G3D score of 24310 and PassMark GPU Compute score of 15667 place it far ahead of the Intel Arc Pro B70, which has no recorded benchmark scores in the database. The NVIDIA card's FP32 throughput of 66.94 TFLOPS versus 22.94 TFLOPS for Intel confirms a dominant compute advantage.

However, the Intel Arc Pro B70 has its own rationale. It offers 32 GB of GDDR6 memory with 608.0 GB/s bandwidth, which is ample for many workstation tasks, and it carries a launch MSRP of 949 USD. The NVIDIA card has no recorded launch MSRP, so direct cost comparison cannot be made from the data. The Intel card also runs at a higher boost clock of 2800 MHz compared to 2377 MHz for NVIDIA, and it consumes 70 W less power under TDP specifications.

For professionals requiring maximum FP32 compute, the highest memory capacity, and the largest transistor count, the NVIDIA RTX PRO 5000 72 GB Blackwell is the data-backed choice. For those prioritizing lower power draw, a smaller die, and a card with a recorded launch price, the Intel Arc Pro B70 is the alternative. The database shows the NVIDIA card at the 37th percentile versus all GPUs, while the Intel card sits at the 50th percentile, but the absence of Intel benchmark scores means the percentile ranking alone does not reflect their relative performance.

Head-to-Head Benchmarks

The database contains benchmark scores only for the NVIDIA RTX PRO 5000 72 GB Blackwell; the Intel Arc Pro B70 has no recorded benchmark entries. The NVIDIA card's PassMark G3D score of 24310 indicates strong rasterization performance. Its PassMark GPU Compute score of 15667 shows significant compute capability. In DirectX-specific PassMark tests, the card scores 311 in DirectX 9, 219 in DirectX 11, 175 in DirectX 10, and 78 in DirectX 12. The PassMark G2D score is 914.

The 3DMark Steel Nomad DX12 score for the NVIDIA card is 9579.5. Its average benchmark score across all recorded tests is 6407. The nearest rivals in the database include the NVIDIA GeForce GTX 460 SE with an average score of 6389 and a delta of 0.3 percent, the NVIDIA GeForce GTX 580M with the same average score and delta, the AMD Radeon Vega 10 Mobile with an average score of 6476 and a delta of -1.1 percent, and the NVIDIA Quadro M5000M with an average score of 6481 and a delta of -1.1 percent.

Because the Intel card has zero recorded benchmarks, the head-to-head comparison is one-sided. The data shows that the NVIDIA card outperforms its nearest rivals by a narrow margin, with deltas of only 0.3 percent and -1.1 percent. This places it in a competitive band with older mobile and midrange desktop parts, despite its high-end specifications.

The lack of Intel benchmark data means no direct score comparison can be made. The database records zero wins for each card in the head-to-head benchmark category, confirming that no paired test results exist.

Specification Differences

The two cards differ across nearly every major specification. The Intel Arc Pro B70 uses the BMG-G31 chip based on Xe2-HPG architecture from the Battlemage (Pro Series) generation. The NVIDIA RTX PRO 5000 72 GB Blackwell uses the GB202 chip based on Blackwell 2.0 architecture from the Blackwell PRO W (x000) generation.

The process node is identical at 5 nm from TSMC for both cards. The die sizes differ significantly: Intel measures 368 mm², while NVIDIA measures 750 mm². The transistor count for Intel is unknown, while NVIDIA has 92,200 million transistors with a density of 122.9M per mm².

Clock speeds differ notably. The Intel card has a base clock of 2280 MHz and a boost clock of 2800 MHz, while the NVIDIA card has a base clock of 1740 MHz and a boost clock of 2377 MHz. Memory clocks also differ: Intel uses 2375 MHz with 19 Gbps effective, while NVIDIA uses 1750 MHz with 28 Gbps effective.

Memory configurations are substantially different. Intel offers 32 GB of GDDR6 on a 256-bit bus with 608.0 GB/s bandwidth. NVIDIA offers 72 GB of GDDR7 on a 384-bit bus with 1.34 TB/s bandwidth. The NVIDIA card has more than double the memory capacity and more than double the bandwidth.

Compute resources favor NVIDIA heavily. The NVIDIA card has 14080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. The Intel card has 4096 shading units, 256 TMUs, 128 ROPs, 32 RT cores, and no listed tensor cores.

Pixel and texture rates follow the same pattern. The NVIDIA card achieves 380.3 GPixel/s and 1,045.9 GTexel/s. The Intel card achieves 358.4 GPixel/s and 716.8 GTexel/s. FP32 performance is 66.94 TFLOPS for NVIDIA versus 22.94 TFLOPS for Intel. FP16 performance is 66.94 TFLOPS (1:1) for NVIDIA versus 45.88 TFLOPS (2:1) for Intel.

Power specifications differ. The Intel card has a TDP of 230 W with a suggested PSU of 550 W and a single 8-pin power connector. The NVIDIA card has a TDP of 300 W with a suggested PSU of 700 W and a single 16-pin power connector.

Architecture Differences

The architectural divide is substantial. Intel's Xe2-HPG architecture on the BMG-G31 chip represents the Battlemage generation, built for the Pro Series. NVIDIA's Blackwell 2.0 architecture on the GB202 chip represents the Blackwell PRO W generation. Both use a 5 nm TSMC process, but the design philosophies diverge sharply.

The Intel card has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. It has no listed tensor cores, indicating a focus on rasterization and ray tracing without dedicated AI acceleration hardware. Its FP16 performance of 45.88 TFLOPS at 2:1 ratio suggests a packed math approach where FP16 throughput is double the FP32 rate.

The NVIDIA card has 14080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. Its FP16 performance matches FP32 at 66.94 TFLOPS with a 1:1 ratio, indicating a different execution model where FP16 and FP32 share the same throughput. The presence of 440 tensor cores gives it dedicated AI compute capability that the Intel card lacks entirely.

The transistor counts reflect the architectural complexity. NVIDIA packs 92,200 million transistors into 750 mm², yielding a density of 122.9M per mm². Intel's transistor count is unknown, but its die size of 368 mm² is less than half the NVIDIA die. The NVIDIA chip is physically much larger and more complex.

Cache and memory hierarchy differences are not recorded in the database, but the memory types differ fundamentally. Intel uses GDDR6, while NVIDIA uses GDDR7. The NVIDIA memory clock of 1750 MHz with 28 Gbps effective transfers data at nearly double the Intel effective rate of 19 Gbps.

The RT core counts differ significantly: 32 for Intel versus 110 for NVIDIA. This indicates substantially different ray tracing throughput potential. The NVIDIA card's 440 tensor cores provide another compute dimension entirely absent from the Intel specifications.

Where Each One Wins

The NVIDIA RTX PRO 5000 72 GB Blackwell wins in all recorded benchmark categories because the Intel card has no benchmark scores in the database. The NVIDIA card's PassMark G3D score of 24310 and GPU Compute score of 15667 establish it as the performance leader in the data we have. Its FP32 throughput of 66.94 TFLOPS is nearly triple the Intel figure, making it the clear choice for raw compute workloads.

Memory capacity strongly favors NVIDIA at 72 GB versus 32 GB. For workloads that require large datasets resident in VRAM, such as rendering scenes with massive textures or running large machine learning models, the NVIDIA card has a decisive advantage. Its memory bandwidth of 1.34 TB/s versus 608.0 GB/s further cements this lead.

The Intel Arc Pro B70 wins on power efficiency. Its TDP of 230 W versus 300 W for NVIDIA means lower peak power draw. The suggested PSU of 550 W versus 700 W indicates a lighter system power requirement. The Intel card also has a higher boost clock of 2800 MHz versus 2377 MHz, which could benefit lightly threaded workloads that scale with clock speed.

The Intel card also has a recorded launch MSRP of 949 USD, while the NVIDIA card has no recorded launch MSRP. The database does not allow price comparisons beyond this single fact.

For professionals working with AI inference and training, the NVIDIA card's 440 tensor cores provide dedicated hardware that the Intel card cannot match. For pure rasterization workloads, the NVIDIA card's 14080 shading units versus 4096 give it a massive parallel execution advantage.

The Intel card's smaller die size of 368 mm² versus 750 mm² suggests lower manufacturing complexity, though transistor counts are unknown for Intel. Its dual-slot design and 267 mm length match the NVIDIA card physically, so chassis compatibility is similar.

In summary, the NVIDIA card dominates in compute performance, memory capacity, memory bandwidth, and feature set. The Intel card counters with lower power draw, higher boost clock, and a recorded launch price. The absence of Intel benchmark scores means all performance conclusions come from the NVIDIA data alone.
