Intel Arc A380M vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries for this pairing, so the comparison rests entirely on the architectural and specification fields. The NVIDIA RTX PRO 4500 Blackwell Server holds the decisive advantage in every compute metric. Its FP32 throughput of 50.70 TFLOPS is more than 12 times the Intel Arc A380M's 4.096 TFLOPS. The FP16 comparison is equally lopsided: the RTX PRO 4500 delivers 50.70 TFLOPS with a 1:1 ratio, while the Arc A380M reaches 8.192 TFLOPS using a 2:1 ratio. That means the NVIDIA part sustains full-rate FP16 across all cores, whereas the Intel part halves its FP16 rate relative to FP32.

Pixel throughput tells a similar story. The RTX PRO 4500 reaches 270.5 GPixel/s against the Arc A380M's 64.00 GPixel/s, a margin of roughly 4.2 times. Texture rate follows the same pattern: 792.1 GTexel/s versus 128.0 GTexel/s, a 6.2 times gap. These are not marginal differences; the NVIDIA part outclasses the Intel part by a wide margin in every raw throughput figure recorded in the database.

Memory bandwidth amplifies the gap further. The RTX PRO 4500 moves 800.3 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 4.3 times bandwidth advantage for NVIDIA. The Arc A380M does hold one clock-related edge: its base clock runs at 1550 MHz versus 1215 MHz for the RTX PRO 4500, and its memory clock of 1937 MHz translates to 15.5 Gbps effective, compared to 1563 MHz and 25 Gbps effective for the NVIDIA part. However, the NVIDIA part boosts higher at 2415 MHz versus 2000 MHz, and the effective memory speed advantage belongs to the RTX PRO 4500.

Both products share the same API support in the database: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Neither has recorded benchmark scores or average scores, and both sit at the 50th percentile among all GPUs in the database. The lack of measured benchmark data means the specification comparison is the only reliable way to differentiate these two parts.

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 TSMC process with 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9 million per square millimeter. The NVIDIA RTX PRO 4500 Blackwell Server uses the GB203 chip with the Blackwell 2.0 architecture, belonging to the Server Blackwell (Bxx) generation. It is built on a 5 nm TSMC process with 45,600 million transistors across a 378 mm² die, for a density of 120.6 million per square millimeter. The NVIDIA chip packs 6.3 times more transistors into a die that is 2.4 times larger, and its transistor density is 2.6 times higher.

The compute resources diverge sharply. The Arc A380M has 1024 shading units, 64 texture mapping units, and 32 ROPs. It includes 8 ray tracing cores but no tensor cores in the recorded data. The RTX PRO 4500 has 10496 shading units, 328 TMUs, and 112 ROPs, with 82 ray tracing cores and 328 tensor cores. The NVIDIA part has 10.25 times the shading units, 5.13 times the TMUs, 3.5 times the ROPs, and 10.25 times the ray tracing cores. The presence of 328 tensor cores on the NVIDIA part versus none recorded for the Intel part marks a fundamental feature divide for AI and compute workloads.

Memory architecture differs completely. The Arc A380M uses 6 GB of GDDR6 on a 96-bit bus. The RTX PRO 4500 uses 32 GB of GDDR7 on a 256-bit bus, a 5.3 times memory capacity advantage and a 2.67 times bus width advantage. The NVIDIA part's GDDR7 memory runs at 25 Gbps effective versus 15.5 Gbps for the Intel part's GDDR6.

Power and physical design also separate the two. The Arc A380M has a 35 W TDP and comes as an MXM Module with an MXM-A (3.1) bus interface. The RTX PRO 4500 has a 165 W TDP, a single-slot form factor, a 16-pin power connector, and a suggested PSU of 450 W. It uses PCIe 5.0 x16, while the Intel part uses the MXM-A interface. The NVIDIA card measures 267 mm in length, 111 mm in height, and 40 mm in width. The Intel module has no recorded dimensions. Display outputs differ as well: the Arc A380M is listed as "Portable Device Dependent," meaning its outputs depend on the host device, while the RTX PRO 4500 has no outputs at all, indicating a compute-only server product.

Release timing is equally distinct. The Arc A380M launched on January 23, 2023. The RTX PRO 4500 launched on March 16, 2026, with a predecessor listed as Server Hopper and a successor listed as Server Rubin. The Intel part has no predecessor or successor recorded in the database.

Where Each One Wins

The Intel Arc A380M wins in power efficiency and form factor flexibility. At 35 W TDP, it draws less than a quarter of the RTX PRO 4500's 165 W TDP. Its MXM module format suits portable or embedded devices where the display outputs are determined by the host system, which is why the database lists its outputs as "Portable Device Dependent." The higher base clock of 1550 MHz gives it a nominal frequency advantage at idle or low load, but that does not translate into any throughput win.

The NVIDIA RTX PRO 4500 wins in every performance category with recorded data. It has more than 10 times the shading units and ray tracing cores, 5.3 times the memory capacity, 4.3 times the memory bandwidth, and over 12 times the FP32 throughput. The 328 tensor cores unlock matrix operations that the Arc A380M cannot perform with dedicated hardware. The 32 GB GDDR7 frame buffer supports workloads that would exhaust the 6 GB GDDR6 pool on the Intel part many times over. The PCIe 5.0 x16 interface provides a far wider host connection than the MXM-A bus.

The use-case split follows these specifications. The Arc A380M suits low-power mobile or embedded deployments where a compact module with flexible display routing is required. The RTX PRO 4500 suits server-side compute, rendering, and AI inference tasks that demand high FP32, FP16, and tensor throughput, large memory capacity, and high bandwidth. The RTX PRO 4500's lack of display outputs confirms its server orientation, while the Arc A380M's device-dependent outputs confirm its role as a module inside a portable product.

Both parts share the same DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 API support, so software compatibility at the API level is identical. The difference lies entirely in the scale of the hardware resources behind those APIs.

The Verdict

The data supports a clear verdict: the NVIDIA RTX PRO 4500 Blackwell Server is the overwhelmingly stronger product for compute-heavy workloads, and the Intel Arc A380M is a low-power mobile module with a completely different role. No benchmark scores exist in the database for either product, so the verdict rests on specification differences, and those differences are enormous.

The RTX PRO 4500 delivers 50.70 TFLOPS FP32, 50.70 TFLOPS FP16, 800.3 GB/s of memory bandwidth, 32 GB of GDDR7, 82 ray tracing cores, and 328 tensor cores. The Arc A380M delivers 4.096 TFLOPS FP32, 8.192 TFLOPS FP16, 186.0 GB/s of bandwidth, 6 GB of GDDR6, 8 ray tracing cores, and no tensor cores. Anyone selecting between these two parts for a server or high-performance compute role should choose the NVIDIA product without hesitation.

The Arc A380M is only preferable where its 35 W TDP, MXM module design, and portable-device-dependent outputs are required. No server or desktop workstation workload in the recorded data favors the Intel part. The RTX PRO 4500 also has the more recent launch date of March 16, 2026, versus January 23, 2023, and a defined successor in Server Rubin, indicating an active product roadmap.

The percentile ranking of 50 for both parts in the database provides no differentiation, and the absence of average benchmark scores leaves the specification sheet as the sole basis for decision-making. Based on that sheet, the RTX PRO 4500 wins every measurable performance category, and the Arc A380M wins only in power draw and form factor flexibility.
