Intel Arc Pro B65 vs NVIDIA RTX PRO 5000 72 GB Blackwell Comparison

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark entries for these two workstation cards, but the recorded measurements for the NVIDIA RTX PRO 5000 72 GB Blackwell provide a useful reference point. The RTX PRO 5000 posts an average benchmark score of 6407 across its eight recorded tests, placing it at the 37th percentile of all GPUs in the database. Its nearest rivals in the database are the NVIDIA GeForce GTX 460 SE and the NVIDIA GeForce GTX 580M, each with an average score of 6389, putting the RTX PRO 5000 a marginal 0.3% ahead of both. The AMD Radeon Vega 10 Mobile and NVIDIA Quadro M5000M each average 6476 and 6481 respectively, with the RTX PRO 5000 trailing both by 1.1%.

The Intel Arc Pro B65 has no recorded benchmark scores in the database, which limits direct numerical comparison. The database places it at the 50th percentile of all GPUs based on its specifications alone, with an average benchmark score of zero due to the absence of test data. This means the percentile ranking for the Intel card is derived from its hardware configuration rather than measured performance.

Breaking down the RTX PRO 5000's individual test results, the strongest showing comes from the PassMark G3D test with a score of 24310. The GPU compute test follows at 15667, indicating substantial compute throughput. The 3DMark Steel Nomad DX12 test records 9579.5, which represents modern DirectX 12 gaming and rendering workloads. Legacy DirectX tests show lower scores: PassMark DirectX 9 records 311, DirectX 11 records 219, and DirectX 10 records 175. The DirectX 12 PassMark test shows 78, notably lower than the 3DMark result for the same API generation, which reflects different workload characteristics between the two test suites. The 2D graphics test records 914.

The Intel Arc Pro B65's FP32 throughput is 12.29 TFLOPS against the RTX PRO 5000's 66.94 TFLOPS, a ratio of roughly 5.4 to 1 in favor of the NVIDIA card. In FP16 compute, the Intel card delivers 24.58 TFLOPS using a 2:1 ratio, while the RTX PRO 5000 delivers 66.94 TFLOPS at a 1:1 ratio, meaning the NVIDIA card maintains its full FP32 rate when computing FP16. Pixel throughput shows 192.0 GPixel/s for Intel versus 380.3 GPixel/s for NVIDIA, while texture rate stands at 384.0 GTexel/s versus 1,045.9 GTexel/s. Memory bandwidth differs substantially: the Intel card provides 608.0 GB/s over a 256-bit bus, while the RTX PRO 5000 delivers 1.34 TB/s over a 384-bit bus.

The Verdict

The data indicates two cards built for different tiers of professional work. The RTX PRO 5000 72 GB Blackwell is the clear performance leader across every measurable specification. Its 66.94 TFLOPS FP32 performance is more than five times the Intel Arc Pro B65's 12.29 TFLOPS. The NVIDIA card also carries 14,080 shading units against 2,560, 440 texture mapping units against 160, and 160 render output units against 80. Ray tracing hardware favors NVIDIA as well, with 110 RT cores versus 20, and the NVIDIA card adds 440 tensor cores where the Intel card has none recorded.

Memory capacity strongly favors NVIDIA: 72 GB of GDDR7 versus 32 GB of GDDR6. The memory type difference matters for bandwidth efficiency. GDDR7 at 28 Gbps effective delivers 1.34 TB/s, while the Intel card's GDDR6 at 19 Gbps effective produces 608.0 GB/s. The RTX PRO 5000 also doubles the transistor count at 92,200 million versus 19,600 million, on a larger die of 750 mm² versus 272 mm².

The RTX PRO 5000's 300 W TDP against the Intel card's 200 W indicates the performance gap comes with higher power consumption. The NVIDIA card requires a 700 W suggested power supply versus 550 W for Intel, and uses a 16-pin connector rather than an 8-pin. Physical dimensions for the NVIDIA card are recorded at 267 mm length, 111 mm height, and 40 mm width, while the Intel card's dimensions are not recorded in the database.

The Intel Arc Pro B65 does hold advantages in certain areas. Its base clock runs at 2400 MHz versus 1740 MHz for NVIDIA, and its boost clock ties at 2400 MHz versus 2377 MHz. The Intel card achieves these clocks at a lower 200 W TDP. Both cards use the same PCIe 5.0 x16 bus interface and offer four DisplayPort outputs, with Intel providing DisplayPort 2.1 and NVIDIA providing DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Users who need maximum compute throughput, large memory capacity for massive datasets, or ray tracing performance should select the RTX PRO 5000 based on the recorded specifications. Users who prioritize lower power draw and are working within a 200 W envelope should consider the Intel Arc Pro B65, provided their workloads fit within 32 GB of memory and the lower compute ceiling.

Architecture Differences

The NVIDIA RTX PRO 5000 uses the Blackwell 2.0 architecture with the GB202 chip, belonging to the Blackwell PRO W (x000) generation. Its predecessor is listed as Workstation Ada. The Intel Arc Pro B65 uses the Xe2-HPG architecture with the BMG-G21 chip, belonging to the Battlemage (Pro Series) generation. Both cards are fabricated on TSMC's 5 nm process, but the NVIDIA chip is substantially larger at 750 mm² versus 272 mm², accommodating 92,200 million transistors versus 19,600 million.

The NVIDIA architecture includes dedicated tensor cores for AI and compute workloads, with 440 tensor cores present. The Intel Xe2-HPG architecture has no tensor cores recorded. Ray tracing hardware differs significantly: 110 RT cores on NVIDIA versus 20 on Intel. The shading unit count disparity of 14,080 versus 2,560 reflects the different scale of the two GPUs.

The NVIDIA card uses GDDR7 memory, the first implementation of this memory type in the database for this comparison, while Intel uses GDDR6. The NVIDIA card's FP16 performance matches its FP32 at a 1:1 ratio, indicating a design without dedicated FP16 acceleration, while the Intel card doubles its FP32 rate for FP16 at a 2:1 ratio. The Intel card operates at higher clock speeds, with both base and boost at 2400 MHz, while NVIDIA boosts to 2377 MHz from a lower 1740 MHz base.

Where Each One Wins

The RTX PRO 5000 wins decisively in raw compute throughput. Its 66.94 TFLOPS FP32 performance supports large simulation, rendering, and compute workloads. The 72 GB memory capacity with 1.34 TB/s bandwidth suits massive datasets, high-resolution textures, and multi-GPU scaling scenarios. The 440 tensor cores provide dedicated hardware for AI inference and training workloads, a capability the Intel card lacks entirely. The 110 RT cores deliver substantially more ray tracing throughput for architectural visualization and film rendering.

The Intel Arc Pro B65 wins on power efficiency. At 200 W TDP, it consumes one-third less power than the RTX PRO 5000's 300 W. The lower power draw also means a lower suggested power supply at 550 W versus 700 W, and a simpler 8-pin connector instead of the 16-pin requirement. The Intel card's higher clock speeds at 2400 MHz base and boost indicate it maintains consistent performance without thermal throttling concerns that could affect the NVIDIA card's boost behavior.

The RTX PRO 5000's benchmark data shows strong compute performance with a PassMark GPU compute score of 15667 and a G3D score of 24310. The 3DMark Steel Nomad score of 9579.5 demonstrates capable DirectX 12 rendering. The Intel card has no recorded benchmark scores, so its real-world performance cannot be verified from the database.

For users with workloads exceeding 32 GB of memory, the RTX PRO 5000 is the only option between the two. For users limited to 200 W power budgets or 550 W power supplies, the Intel Arc Pro B65 fits within those constraints. The RTX PRO 5000's 267 mm length requires case clearance, while the Intel card's dimensions are not recorded, making physical fit unknown for the Intel card. Both cards offer four DisplayPort outputs, so multi-monitor setups are equally supported.
