Intel Arc A380M vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the Intel Arc A380M or the NVIDIA RTX PRO 4500 Blackwell Workstation. Both entries show an average benchmark score of 0, and the head-to-head benchmark array is empty. This means there are no direct performance comparisons available from the recorded data.

However, the raw specifications allow for a computed comparison of theoretical throughput limits. The RTX PRO 4500 delivers 50.53 TFLOPS of FP32 compute, which is 12.3 times higher than the Arc A380M's 4.096 TFLOPS. In FP16, the gap narrows slightly but remains substantial: the RTX PRO 4500 maintains 50.53 TFLOPS at a 1:1 ratio, while the Arc A380M reaches 8.192 TFLOPS via a 2:1 ratio, making the NVIDIA card 6.2 times faster.

Memory bandwidth shows a similar disparity. The RTX PRO 4500 accesses 896.0 GB/s across a 256-bit GDDR7 interface, while the Arc A380M manages 186.0 GB/s over a 96-bit GDDR6 bus. That is a 4.8 times advantage for NVIDIA. Pixel throughput favors the RTX PRO 4500 at 269.6 GPixel/s versus 64.00 GPixel/s for the Intel part, a 4.2 times margin. Texture rate is even more lopsided: 789.5 GTexel/s versus 128.0 GTexel/s, a 6.2 times difference.

These figures represent theoretical ceilings, not measured application performance. The absence of actual benchmark data means real-world deltas could differ, but the specification gaps are so large that the RTX PRO 4500 would be expected to dominate in any compute or graphics workload that scales with raw throughput.

Architecture Differences

The Intel Arc A380M uses the DG2-128 chip built on the Xe-HPG architecture, part of the Alchemist generation for Arc 3 Mobile. It is fabricated on a 6 nm process at TSMC. The die measures 157 mm² and packs 7,200 million transistors, yielding a transistor density of 45.9M per mm².

The NVIDIA RTX PRO 4500 Blackwell Workstation uses the GB203 chip on the Blackwell 2.0 architecture, from the Blackwell PRO W (x000) generation. It is built on a 5 nm process, also at TSMC. The die is 378 mm² with 45,600 million transistors, achieving a transistor density of 120.6M per mm², which is 2.6 times denser than the Intel chip.

Compute resources differ drastically. The Arc A380M has 1024 shading units, 64 texture mapping units, 32 raster output units, and 8 ray tracing cores. It has no dedicated tensor cores. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The NVIDIA card has 10.3 times more shading units, 5.1 times more TMUs, 3.5 times more ROPs, and 10.3 times more RT cores.

Memory architecture diverges completely. The Intel card uses 6 GB of GDDR6 on a 96-bit bus. The NVIDIA card uses 32 GB of GDDR7 on a 256-bit bus. Clock behavior also differs: the Arc A380M runs memory at 1937 MHz with 15.5 Gbps effective speed, while the RTX PRO 4500 runs memory at 1750 MHz with 28 Gbps effective speed.

Physical design separates the two clearly. The Arc A380M is an MXM module with MXM-A (3.1) bus interface and portable-device-dependent display outputs. The RTX PRO 4500 is a dual-slot PCIe 5.0 x16 card measuring 267 mm by 111 mm by 40 mm, with 4x DisplayPort 2.1b outputs. The NVIDIA card requires a 16-pin power connector and 550 W suggested PSU, while the Intel module takes power through its MXM connector.

FP16 processing differs in ratio. The Arc A380M halves FP16 throughput to 8.192 TFLOPS relative to FP32, using a 2:1 ratio. The RTX PRO 4500 delivers 50.53 TFLOPS in both FP16 and FP32 at a 1:1 ratio, meaning no penalty for half-precision work.

The Verdict

The recorded data provides no benchmark scores for either GPU, so any verdict must derive entirely from specification comparison. The NVIDIA RTX PRO 4500 Blackwell Workstation dominates every measurable compute and memory metric. It has 12.3 times the FP32 throughput, 6.2 times the FP16 throughput, 4.8 times the memory bandwidth, 4.2 times the pixel rate, and 6.2 times the texture rate. It also carries 10.3 times the shading units, 10.3 times the RT cores, and 41 times the tensor cores, the latter being absent from the Intel part entirely.

For workloads that require large memory capacity, the RTX PRO 4500's 32 GB versus 6 GB is a decisive factor. For bandwidth-sensitive tasks, the 896.0 GB/s GDDR7 implementation leaves the 186.0 GB/s GDDR6 bus far behind. The NVIDIA card also runs at higher boost clocks, 2407 MHz versus 2000 MHz, and benefits from a more advanced 5 nm process with higher transistor density.

The Arc A380M is not without merit. Its 35 W TDP makes it suitable for compact MXM-based systems where power and space are constrained. The RTX PRO 4500 requires 200 W, a dual-slot footprint, and a 550 W PSU. For applications that fit within the Intel card's 6 GB memory and modest compute envelope, the lower power draw and smaller physical profile are genuine advantages.

The data indicates the RTX PRO 4500 is the superior performer in absolute terms. The Arc A380M exists in a different class, targeting low-power mobile or embedded scenarios. Neither card can substitute for the other without significant compromises.

Where Each One Wins

The RTX PRO 4500 wins every raw compute category in the recorded specifications. It delivers 50.53 TFLOPS FP32 versus 4.096 TFLOPS, and 50.53 TFLOPS FP16 versus 8.192 TFLOPS. For AI and machine learning workloads, its 328 tensor cores give it capabilities the Arc A380M lacks entirely. The 32 GB GDDR7 frame buffer with 896.0 GB/s bandwidth supports large datasets and high-resolution rendering that the 6 GB GDDR6 configuration cannot accommodate.

The Arc A380M wins on power efficiency and physical flexibility. At 35 W TDP, it consumes 5.7 times less power than the RTX PRO 4500's 200 W. Its MXM form factor allows integration into slim laptops or embedded systems where a dual-slot PCIe card would not fit. The portable-device-dependent display outputs mean it can adapt to whatever panel or connector the host device provides, whereas the RTX PRO 4500 is fixed to 4x DisplayPort 2.1b.

In workload-specific terms, the RTX PRO 4500 suits professional 3D rendering, large-scale simulation, video processing at high resolutions, and any task requiring more than 6 GB of memory. The Arc A380M fits lightweight graphics, basic compute, and power-constrained mobile deployments. The absence of tensor cores on the Intel part also limits its use in modern AI-accelerated applications, while the RTX PRO 4500's 328 tensor cores make such workloads its primary strength.
