The Verdict

The recorded data presents a clear separation between these two products. The NVIDIA RTX PRO 4500 Blackwell delivers 50.53 TFLOPS of FP32 compute, 896.0 GB/s of memory bandwidth, and 32 GB of GDDR7 memory. It ranks at the 76th percentile among all GPUs, with an average benchmark score of 31,532. Its nearest rivals in the database include the NVIDIA TITAN RTX (average score 31,676, delta -0.5%), the Intel Arc Pro A30M (average score 31,894, delta -1.1%), the NVIDIA GRID M60-1Q (average score 31,220, delta +1%), and the NVIDIA Quadro M5000 (average score 31,206, delta +1%).

The Intel Arc A380E has no recorded benchmark scores in the database, which limits direct performance comparison. Its specifications indicate a much smaller footprint: 4.096 TFLOPS FP32, 186.0 GB/s memory bandwidth, and 6 GB of GDDR6 memory. It holds the 50th percentile position, but that ranking is based on the absence of measured performance data rather than competitive results.

Benchmark results indicate that the NVIDIA RTX PRO 4500 Blackwell is the higher-performing part across every measurable dimension. Its FP32 throughput is approximately 12 times higher than the Intel part. Its texture rate of 789.5 GTexel/s dwarfs the 128.0 GTexel/s of the Arc A380E. Pixel rate is similarly lopsided: 269.6 GPixel/s versus 64.00 GPixel/s. The NVIDIA GPU also carries 82 RT cores and 328 tensor cores, while the Intel GPU lists 8 RT cores and no tensor core count.

For users requiring professional-grade compute, large memory capacity, or ray tracing and tensor workloads, the data clearly points to the NVIDIA RTX PRO 4500 Blackwell. The Intel Arc A380E, with its 75 W TDP and single-slot design, serves a different purpose: low-power, compact, and adequate for lighter graphics workloads. The production status also matters: the Intel part is end-of-life, while the NVIDIA part remains active. The RTX PRO 4500 Blackwell is the only one of the two with measurable performance data, and that data places it firmly in the upper tier of the database.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database contains no direct comparative test results between these two GPUs. However, the NVIDIA RTX PRO 4500 Blackwell has its own benchmark suite recorded, and those scores provide context for its standing.

In 3DMark Steel Nomad DX12, the RTX PRO 4500 Blackwell scores 7,025. In Geekbench Vulkan, it scores 221,768. PassMark results show 33,360 in G3D, 19,255 in GPU compute, 1,336 in G2D, 397 in DirectX 9, 320 in DirectX 11, 204 in DirectX 10, and 119 in DirectX 12.

The Intel Arc A380E has no benchmark entries in the database. This absence of data means the comparison is one-sided. The recorded data shows that the RTX PRO 4500 Blackwell's average benchmark score of 31,532 places it within 0.5% of the NVIDIA TITAN RTX (31,676) and 1.1% of the Intel Arc Pro A30M (31,894). It sits 1% above both the NVIDIA GRID M60-1Q (31,220) and the NVIDIA Quadro M5000 (31,206).

The FP32 compute gap is the most striking numerical difference. The RTX PRO 4500 Blackwell delivers 50.53 TFLOPS, while the Arc A380E delivers 4.096 TFLOPS. That is a 46.43 TFLOPS difference in favor of the NVIDIA card. Memory bandwidth tells a similar story: 896.0 GB/s versus 186.0 GB/s, a difference of 710 GB/s. The shading unit count is 10,496 for NVIDIA versus 1,024 for Intel. Texture mapping units number 328 versus 64. Render output units number 112 versus 32.

The NVIDIA card also runs at a higher boost clock of 2,407 MHz compared to the Intel card's 2,000 MHz boost. Its memory operates at 28 Gbps effective versus 15.5 Gbps effective. The bus interface is PCIe 5.0 x16 for NVIDIA, while Intel uses PCIe 4.0 x8. Display outputs are 4x DisplayPort 2.1b on the NVIDIA card and 4x DisplayPort 2.0 on the Intel card.

The NVIDIA card offers a wider memory bus, newer memory technology, and more than ten times the shading units. The Intel card is smaller, consumes less power, and uses a narrower PCIe link. The RTX PRO 4500 Blackwell is longer but shorter in height than the Arc A380E, and it is twice as thick.

Architecture Differences

The Intel Arc A380E uses the DG2-128 chip based on the Xe-HPG architecture, fabricated on a 6 nm process at TSMC. Its predecessor is Xe Graphics and its successor is Battlemage. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GPU has 8 RT cores and no tensor core count listed. FP16 throughput is 8.192 TFLOPS at a 2:1 ratio relative to FP32, indicating that the hardware uses a packed math approach rather than dedicated full-rate FP16 execution.

The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip based on the Blackwell 2.0 architecture, also fabricated at TSMC but on a 5 nm process. Its predecessor is Workstation Ada. The architecture also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The GPU has 82 RT cores and 328 tensor cores. FP16 throughput matches FP32 at 50.53 TFLOPS with a 1:1 ratio, indicating full-rate FP16 execution across the shading units. The tensor core count of 328 equals the TMU count, which is typical for NVIDIA architectures where tensor cores are paired with texture units.

The transistor density difference reflects the process node gap: 45.9M per mm² for Intel on 6 nm versus 120.6M per mm² for NVIDIA on 5 nm. The NVIDIA die is 378 mm², more than twice the Intel die size of 157 mm². The NVIDIA chip integrates 45,600 million transistors, approximately 6.3 times the transistor count of the Intel chip.

The memory architecture also differs fundamentally. The Intel card uses GDDR6 with a 96-bit bus, while the NVIDIA card uses GDDR7 with a 256-bit bus. The effective memory speed is 15.5 Gbps for Intel and 28 Gbps for NVIDIA. The NVIDIA card's memory bandwidth of 896.0 GB/s is nearly five times that of the Intel card's 186.0 GB/s.

The RT core count difference (82 versus 8) indicates a substantial gap in ray tracing capability. The tensor core presence on the NVIDIA card, with 328 units, enables AI and deep learning workloads that the Intel card cannot accelerate through dedicated tensor hardware. The FP16 execution ratio (1:1 versus 2:1) further separates the compute capabilities, with the NVIDIA card maintaining full throughput at half precision.
