Intel Arc A380E vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Intel Arc A380E and NVIDIA RTX PRO 4500 Blackwell Workstation occupy very different positions in the database. The Arc A380E is an entry-level, end-of-life Alchemist part with a 50th percentile ranking, while the RTX PRO 4500 is an active, high-end Blackwell workstation card, also at the 50th percentile but with vastly higher raw specifications. The data indicates these are not direct competitors; the A380E suits basic display and low-power compute tasks, whereas the RTX PRO 4500 delivers heavy rendering and AI workloads. The recorded specifications show a 12.3x difference in FP32 throughput, a 4.8x difference in memory bandwidth, and a 2.7x difference in TDP, so the choice depends entirely on workload scale and power budget.

The Verdict

The database positions the Intel Arc A380E as a low-profile, single-slot, 75 W card with 6 GB GDDR6 and 4.096 TFLOPS FP32. It is end-of-life, with its successor listed as Battlemage. This card is appropriate for systems requiring basic multi-display output (4x DisplayPort 2.0) without auxiliary power connectors, and its 250 W suggested PSU makes it suitable for compact or legacy builds. The 50th percentile ranking indicates mid-pack performance relative to all GPUs, but its absolute scores are low.

The NVIDIA RTX PRO 4500 Blackwell Workstation is a dual-slot, 200 W card with 32 GB GDDR7 and 50.53 TFLOPS FP32. It is active production, uses a PCIe 5.0 x16 interface, and requires a 550 W PSU and a 16-pin power connector. The 50th percentile ranking matches the A380E, but this is misleading: the percentile is relative to all GPUs, and the absolute specification gap is enormous. The RTX PRO 4500 has 10.25x the shading units, 82 RT cores versus 8, and 328 tensor cores versus none on the A380E.

For a user with basic needs, the Arc A380E provides a functional, low-power path. For professional 3D, simulation, or AI tasks, the RTX PRO 4500 is the only viable option from these two, given its 32 GB memory and 896 GB/s bandwidth. The data shows no benchmark scores or head-to-head results, so the verdict rests on specifications: the A380E is a display adapter with light compute, the RTX PRO 4500 is a workstation compute engine.

Architecture Differences

The two GPUs come from different architecture generations. Intel uses Xe-HPG on a TSMC 6 nm process, packing 7,200 million transistors on a 157 mm² die with a density of 45.9 million transistors per mm². NVIDIA uses Blackwell 2.0 on TSMC 5 nm, with 45,600 million transistors on a 378 mm² die, achieving 120.6 million transistors per mm². That is a 6.33x transistor count increase and a 2.63x density advantage for NVIDIA.

The A380E has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores. It has no tensor cores, so AI acceleration relies on general-purpose shaders. Its FP16 throughput is 8.192 TFLOPS (2:1 ratio), which is double FP32, indicating a consumer-oriented design without dedicated tensor hardware.

The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. Its FP16 throughput is 50.53 TFLOPS (1:1 ratio), meaning FP16 does not get a doubling advantage. The presence of 328 tensor cores provides dedicated matrix math acceleration, which is critical for neural network training and inference. The RT core count (82 versus 8) suggests a 10.25x difference in ray tracing hardware.

Memory architecture differs fundamentally. The A380E uses 6 GB GDDR6 on a 96-bit bus, yielding 186 GB/s. The RTX PRO 4500 uses 32 GB GDDR7 on a 256-bit bus, yielding 896 GB/s. That is a 4.82x bandwidth advantage and a 5.33x capacity advantage. The GDDR7 memory clock is 1750 MHz (28 Gbps effective) versus 1937 MHz (15.5 Gbps effective) on GDDR6, so the bandwidth gain comes from the wider bus and higher data rate.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the A380E has 4x DisplayPort 2.0, while the RTX PRO 4500 has 4x DisplayPort 2.1b, a newer revision but the same port count.

Head-to-Head Benchmarks

The database lists zero head-to-head benchmark results for these two cards. There are no recorded wins for either, and no benchmark scores exist. Therefore, comparisons must rely on specification-derived performance estimates. The FP32 throughput gap is the clearest indicator: 4.096 TFLOPS on the A380E versus 50.53 TFLOPS on the RTX PRO 4500, a 12.34x difference. This translates directly to compute-heavy tasks like physics simulation or large matrix operations.

Texture rate shows a 6.17x gap: 128 GTexel/s versus 789.5 GTexel/s. Pixel rate shows a 4.21x gap: 64 GPixel/s versus 269.6 GPixel/s. These rates affect fill-rate-bound rendering, such as high-resolution textures or multi-sampled anti-aliasing. The RTX PRO 4500 also has 82 RT cores versus 8, and 328 tensor cores versus none, so ray tracing and AI inference workloads would see even larger relative differences.

Memory bandwidth is the most impactful for large datasets: 186 GB/s versus 896 GB/s. A 32 GB VRAM pool allows working sets that the 6 GB A380E cannot even load. For example, a large language model or a high-resolution 3D scene requiring more than 6 GB would fail on the A380E. The data shows no overlap in practical capacity.

The RTX PRO 4500 has a higher boost clock at 2407 MHz versus 2000 MHz (no boost on the A380E, base equals boost). However, the A380E has a higher base clock at 2000 MHz versus 1635 MHz. The NVIDIA card compensates with far more cores, so the clock difference is irrelevant in aggregate.

Where Each One Wins

The Arc A380E wins on power efficiency and physical simplicity. Its 75 W TDP requires no auxiliary power, fits in a single slot, measures 254 mm long, 127 mm high, and 20 mm wide, and needs only a 250 W PSU. It also has a higher base clock (2000 MHz versus 1635 MHz), which benefits lightly threaded or latency-sensitive tasks where clock speed matters more than core count. Its 6 GB GDDR6 on a 96-bit bus is adequate for basic multi-monitor setups (4x DisplayPort 2.0) and 2D/light 3D workflows. The PCIe 4.0 x8 interface is sufficient for its bandwidth. The A380E is the only card here that can run without a 16-pin power cable, making it viable for older or small-form-factor systems.

The RTX PRO 4500 wins on every compute and memory metric. Its 32 GB GDDR7 memory allows loading datasets that would exceed the A380E's 6 GB capacity entirely. Its 896 GB/s bandwidth is 4.82x higher, which accelerates large texture streaming, scientific visualization, and in-memory model inference. The 10,496 shading units deliver 50.53 TFLOPS FP32, a 12.34x advantage over the A380E, so any FP32-heavy workload (simulation, rendering, video processing) will finish far faster. The 328 tensor cores enable AI training and inference, which the A380E cannot do with dedicated hardware. The 82 RT cores provide 10.25x the ray tracing hardware, making the RTX PRO 4500 suitable for photorealistic rendering with ray-traced effects. The PCIe 5.0 x16 interface doubles the bus bandwidth for data transfer from host memory or storage.

In specific use cases: for a compact, low-power workstation that drives four displays and runs basic CAD or web-based 3D, the A380E delivers adequate performance with minimal infrastructure. For a professional rendering node, AI development box, or large-scale simulation, the RTX PRO 4500 is the only choice between these two, given the 32 GB memory and 50.53 TFLOPS FP32. The database shows no head-to-head results, but the specification deltas are so large that the RTX PRO 4500 would dominate in any compute-bound task. The A380E wins solely on power draw, size, and connector simplicity.
