Intel Arc Pro B70 vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

The Verdict

The Intel Arc Pro B70 and NVIDIA RTX PRO 4500 Blackwell Server target fundamentally different deployment scenarios, and the recorded data makes the separation clear. The Arc Pro B70 is the general-purpose professional graphics card, with a 949 USD launch MSRP, display outputs, and a dual-slot footprint. The RTX PRO 4500 is a server-focused accelerator with no display outputs and a single-slot design. Neither card shows a benchmark advantage in the database, as both hold a 50th percentile position among all GPUs and have zero recorded benchmark scores. The decision rests entirely on workload type and physical integration requirements.

For rendering, content creation, and any workstation task requiring video output, the Arc Pro B70 is the only option with display connectivity. For compute-heavy server deployments where physical space and power draw are the primary constraints, the RTX PRO 4500 delivers substantially higher raw compute throughput in a single-slot, 165 W envelope. The data does not support a universal winner; it supports a clear split by use case.

Where Each One Wins

The RTX PRO 4500 wins decisively on raw compute performance. Its FP32 throughput of 50.70 TFLOPS is more than double the Arc Pro B70's 22.94 TFLOPS. The NVIDIA card also leads in FP16 compute at 50.70 TFLOPS (1:1) versus 45.88 TFLOPS (2:1) for Intel, though the Intel ratio means its FP16 figure is achieved via packed operations. Texture rate favors NVIDIA at 792.1 GTexel/s versus 716.8 GTexel/s. The RTX PRO 4500 also has more shading units (10496 versus 4096), more TMUs (328 versus 256), and more RT cores (82 versus 32).

The Arc Pro B70 wins on pixel throughput. Its 358.4 GPixel/s pixel rate exceeds the RTX PRO 4500's 270.5 GPixel/s. The Intel card also carries 128 ROPs against NVIDIA's 112 ROPs. Memory bandwidth favors the RTX PRO 4500 at 800.3 GB/s versus 608.0 GB/s, but the Intel card matches the NVIDIA card's 32 GB capacity. The Arc Pro B70's dual-slot design and 1x 8-pin power connector make it more compatible with standard workstation power supplies, while the NVIDIA card's single-slot form factor suits dense server chassis.

Architecture Differences

The two cards use different silicon from different design lineages. The Arc Pro B70 uses the BMG-G31 chip built on TSMC's 5 nm process, measuring 368 mm². It is part of the Xe2-HPG architecture, specifically the Battlemage Pro Series generation. The RTX PRO 4500 uses the GB203 chip, also on TSMC's 5 nm process, measuring 378 mm². The NVIDIA part belongs to the Blackwell 2.0 architecture and the Server Blackwell (Bxx) generation.

Transistor counts differ substantially. The RTX PRO 4500 packs 45,600 million transistors, while the Arc Pro B70's transistor count is not recorded. This yields a transistor density of 120.6M per mm² for the NVIDIA chip. The Intel card's die is 10 mm² smaller, but without its transistor count, density cannot be compared directly.

Clock behavior diverges significantly. The Arc Pro B70 has a base clock of 2280 MHz and a boost of 2800 MHz. The RTX PRO 4500 runs at 1215 MHz base and 2415 MHz boost. Despite the lower clocks, the NVIDIA card achieves much higher compute throughput due to its larger execution resource count. Memory clock also differs: Intel uses 2375 MHz (19 Gbps effective) GDDR6, while NVIDIA uses 1563 MHz (25 Gbps effective) GDDR7.

The RTX PRO 4500 includes 328 tensor cores, a feature class the Arc Pro B70 does not list. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card has no display outputs, while the Intel card provides 1x HDMI 2.1a and 3x DisplayPort 2.1.

Head-to-Head Benchmarks

The database records no benchmark scores for either card, and the head-to-head benchmark array is empty. This means the comparison must rely on the specification-derived performance metrics recorded in the database. The most significant compute gap appears in FP32 throughput. The RTX PRO 4500's 50.70 TFLOPS is 2.21 times the Arc Pro B70's 22.94 TFLOPS. In absolute terms, the NVIDIA card processes an additional 27.76 TFLOPS of single-precision work per second.

FP16 performance shows a different relationship. The RTX PRO 4500 achieves 50.70 TFLOPS with a 1:1 ratio, meaning it handles FP16 at the same rate as FP32. The Arc Pro B70 achieves 45.88 TFLOPS but with a 2:1 ratio, meaning its FP16 rate is double its FP32 rate via packed execution. The NVIDIA card still leads by 4.82 TFLOPS, but the Intel implementation narrows the gap in this precision class.

Texture throughput favors NVIDIA by a narrower margin. The RTX PRO 4500's 792.1 GTexel/s is 10.5% ahead of the Arc Pro B70's 716.8 GTexel/s. Pixel rate is the one rasterization metric where Intel leads: 358.4 GPixel/s versus 270.5 GPixel/s, a 32.5% advantage. This suggests the Arc Pro B70 is better suited to fill-rate-bound rendering workloads, while the RTX PRO 4500 excels at shader and compute-bound tasks.

Memory bandwidth favors NVIDIA by 31.6%, with 800.3 GB/s versus 608.0 GB/s. The GDDR7 memory on the NVIDIA card runs at 25 Gbps effective versus 19 Gbps on the Intel card's GDDR6. Both use a 256-bit bus. The NVIDIA card's higher bandwidth supports its larger compute throughput, while the Intel card's bandwidth is sufficient for its pixel-rate-oriented design.

Specification Differences

The two cards differ across nearly every measured specification. Process node is identical (TSMC 5 nm), but die size differs by 10 mm²: 368 mm² for Intel, 378 mm² for NVIDIA. The NVIDIA chip contains 45,600 million transistors, while the Intel transistor count is unknown. Clock speeds are substantially different, with Intel running much higher base and boost clocks (2280/2800 MHz versus 1215/2415 MHz).

Memory configuration diverges in type and bandwidth. Both use 32 GB on a 256-bit bus, but Intel uses GDDR6 at 2375 MHz (19 Gbps effective), yielding 608.0 GB/s. NVIDIA uses GDDR7 at 1563 MHz (25 Gbps effective), yielding 800.3 GB/s. The execution resource counts show NVIDIA's advantage: 10496 shading units versus 4096, 328 TMUs versus 256, and 82 RT cores versus 32. Intel has more ROPs (128 versus 112). NVIDIA also lists 328 tensor cores; Intel does not list a tensor core count.

Power and physical specifications differ meaningfully. The RTX PRO 4500 draws 165 W with a suggested 450 W PSU, uses a single-slot design, and requires a 1x 16-pin power connector. The Arc Pro B70 draws 230 W with a suggested 550 W PSU, uses a dual-slot design, and requires a 1x 8-pin connector. Both are 267 mm long; NVIDIA is 111 mm tall and 40 mm wide, Intel is 110 mm tall and 39 mm wide. Display outputs are exclusive to Intel (1x HDMI 2.1a, 3x DisplayPort 2.1); NVIDIA has none. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card is marked Active in production status, with a Server Hopper predecessor and Server Rubin successor. Release dates are nine days apart: Intel on 2026-03-25, NVIDIA on 2026-03-16. The Intel card has a launch MSRP of 949 USD; the NVIDIA card has no recorded MSRP.
