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

The Verdict

The data indicates two distinctly positioned workstation GPUs. The NVIDIA RTX PRO 4500 Blackwell Workstation is the raw compute leader, delivering more than double the FP32 throughput of the Intel Arc Pro B70 (50.53 TFLOPS vs. 22.94 TFLOPS) while consuming 30 W less power (200 W vs. 230 W). It also offers substantially higher memory bandwidth (896.0 GB/s vs. 608.0 GB/s) and a larger shader count (10496 vs. 4096). For professionals running compute-heavy workloads, the NVIDIA card is the clear choice based on these specifications.

The Intel Arc Pro B70 counters with a higher boost clock (2800 MHz vs. 2407 MHz), a higher base clock (2280 MHz vs. 1635 MHz), and a higher pixel rate (358.4 GPixel/s vs. 269.6 GPixel/s). Its rendering throughput metrics suggest a different strength profile. The data shows the Intel card is the better pick for pixel-pushing tasks and for users needing HDMI 2.1a output, while the NVIDIA card dominates in shader throughput and memory-intensive operations.

Both cards share the same 32 GB memory capacity, PCIe 5.0 x16 interface, and dual-slot form factor. The RTX PRO 4500 uses 1x 16-pin power, whereas the Arc Pro B70 uses 1x 8-pin. The Intel card has a recorded launch MSRP of 949 USD. The NVIDIA card has no launch MSRP in the database.

Architecture Differences

The Intel Arc Pro B70 is built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation, using the BMG-G31 chip. The NVIDIA RTX PRO 4500 Blackwell Workstation uses the Blackwell 2.0 architecture with the GB203 chip, part of the Blackwell PRO W (x000) generation. Both are fabricated by TSMC on a 5 nm process, but the die sizes differ slightly: Intel measures 368 mm², NVIDIA measures 378 mm².

Transistor counts differ significantly. The NVIDIA chip contains 45,600 million transistors, while the Intel chip's transistor count is unknown in the database. The NVIDIA die has a transistor density of 120.6M / mm². The Intel die's density is not recorded.

Core configurations show a major divergence. The NVIDIA card features 10496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The Intel card has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, with no tensor cores listed. This difference explains the compute gap: NVIDIA's FP32 rating of 50.53 TFLOPS is more than double Intel's 22.94 TFLOPS.

Memory architecture also differs. Intel uses 32 GB of GDDR6 on a 256-bit bus, achieving 608.0 GB/s bandwidth. NVIDIA uses 32 GB of GDDR7 on a 256-bit bus, achieving 896.0 GB/s bandwidth. Clock speeds on the memory differ as well: Intel runs at 2375 MHz (19 Gbps effective), NVIDIA at 1750 MHz (28 Gbps effective).

The RTX PRO 4500 is the successor to Workstation Ada per the database. Its production status is Active, while the Arc Pro B70's production status is not listed. The NVIDIA card's release date is 2025-03-17, and the Intel card's release date is 2026-03-25.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Workstation wins in raw compute density and bandwidth. Its FP32 throughput (50.53 TFLOPS) is 120% higher than the Intel card's (22.94 TFLOPS). Its FP16 performance is also 50.53 TFLOPS at 1:1 ratio, whereas the Intel card achieves 45.88 TFLOPS at 2:1 ratio. The NVIDIA card's memory bandwidth of 896.0 GB/s is 47% higher than Intel's 608.0 GB/s. The texture rate favors NVIDIA as well: 789.5 GTexel/s vs. 716.8 GTexel/s.

The Intel Arc Pro B70 wins in pixel processing and clock speeds. Its pixel rate of 358.4 GPixel/s is 33% higher than NVIDIA's 269.6 GPixel/s. The boost clock of 2800 MHz is 16% higher than NVIDIA's 2407 MHz. The base clock of 2280 MHz is 39% higher than NVIDIA's 1635 MHz. These metrics indicate the Intel card is optimized for fill-rate-bound rendering workloads.

The Intel card also offers more ROPs (128 vs. 112), which aligns with its pixel rate advantage. The NVIDIA card offers more TMUs (328 vs. 256) and more RT cores (82 vs. 32), suggesting stronger ray tracing and texture-heavy performance.

Power draw favors NVIDIA. The RTX PRO 4500 uses 200 W versus Intel's 230 W, meaning the NVIDIA card delivers higher compute performance at lower power. Both cards suggest a 550 W PSU, and both are dual-slot with identical 267 mm length.
