Intel Arc A380E vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Head-to-Head Benchmarks

The recorded data provides no direct head-to-head benchmark results between the Intel Arc A380E and the NVIDIA RTX PRO 4500 Blackwell Server. Both products sit at the 50th percentile in the database, with an average benchmark score of zero for each. The wins column shows zero for both, meaning no comparative performance tests have been logged. Without measured scores, the comparison must rely entirely on the architectural specifications and calculated throughput figures recorded in the database.

The most significant numerical gap appears in raw compute throughput. The RTX PRO 4500 delivers 50.70 TFLOPS of FP32 performance, while the Arc A380E reaches 4.096 TFLOPS. That places the NVIDIA product 12.4 times higher in single-precision floating-point work. For FP16, the gap narrows slightly in relative terms: the RTX PRO 4500 maintains 50.70 TFLOPS with a 1:1 ratio, while the Arc A380E achieves 8.192 TFLOPS with a 2:1 ratio. The NVIDIA card still leads by a factor of 6.2, but the Intel part's FP16 advantage over its own FP32 figure indicates a different compute design philosophy.

Memory bandwidth shows a similar disparity. The RTX PRO 4500 reaches 800.3 GB/s across a 256-bit GDDR7 bus, while the Arc A380E manages 186.0 GB/s over a 96-bit GDDR6 interface. That is a 4.3-fold difference in favor of NVIDIA. The pixel throughput numbers reinforce the pattern: 270.5 GPixel/s for the RTX PRO 4500 versus 64.00 GPixel/s for the Arc A380E. Texture rate tells the same story at 792.1 GTexel/s versus 128.0 GTexel/s, a 6.2 times advantage.

Clock behavior differs substantially. The Arc A380E operates at a flat 2000 MHz for both base and boost, indicating a fixed operating point. The RTX PRO 4500 has a base clock of 1215 MHz and a boost of 2415 MHz, giving it a 99% uplift under load. The NVIDIA card's memory clock of 1563 MHz translates to 25 Gbps effective, while the Intel part's 1937 MHz memory clock yields 15.5 Gbps effective.

The Verdict

The data separates these two products into distinct performance classes. The RTX PRO 4500 leads in every recorded throughput metric: FP32, FP16, pixel rate, texture rate, and memory bandwidth. Its shading unit count of 10496 versus 1024 gives it a 10.25 times raw parallel processing advantage. The RTX PRO 4500 also carries 82 RT cores and 328 tensor cores, while the Arc A380E has 8 RT cores and no tensor core entry in the database.

The Arc A380E does hold advantages in specific physical and operational areas. It draws 75 W versus 165 W, uses no external power connectors, and requires a 250 W suggested PSU compared to 450 W for the RTX PRO 4500. It is also shorter at 254 mm versus 267 mm, though both are single-slot cards. The Intel part provides 4x DisplayPort 2.0 outputs, while the NVIDIA server card has no display outputs at all. For systems requiring on-card video output, the Arc A380E is the only option between the two.

The RTX PRO 4500 targets server deployment with its PCIe 5.0 x16 interface, 32 GB of GDDR7 memory, and absence of display connections. The Arc A380E, with its PCIe 4.0 x8 interface, 6 GB of GDDR6 memory, and four display outputs, aligns with client-side graphics duties. The production status confirms the positioning: the Arc A380E is end-of-life, while the RTX PRO 4500 remains active.

Where Each One Wins

Compute-heavy server workloads: The RTX PRO 4500 wins decisively. Its 50.70 TFLOPS FP32 and FP16 figures, combined with 328 tensor cores, make it the clear choice for parallel compute tasks. The 32 GB memory capacity supports larger datasets, and the 800.3 GB/s bandwidth moves data substantially faster than the Arc A380E's 186.0 GB/s.

Rasterization and graphics throughput: The RTX PRO 4500 again leads with 270.5 GPixel/s and 792.1 GTexel/s. Its 112 ROPs and 328 TMUs outnumber the Arc A380E's 32 ROPs and 64 TMUs by wide margins. Any workload that depends on pixel fill or texture sampling favors the NVIDIA part.

Ray tracing: The RTX PRO 4500 has 82 RT cores versus 8 on the Arc A380E. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is equal. The hardware capacity for ray tracing is not equal, however.

Low-power or display-equipped systems: The Arc A380E wins on power draw at 75 W, requires no power connectors, and provides four DisplayPort 2.0 outputs. The RTX PRO 4500 has no display outputs and needs a single 16-pin connector. For a system that must output video and stay within a modest power envelope, the Intel part is the functional choice.

Memory capacity and bandwidth: The RTX PRO 4500 provides 32 GB of GDDR7 over a 256-bit bus versus 6 GB of GDDR6 over a 96-bit bus. The NVIDIA card holds a 4.3 times bandwidth advantage and over five times the memory capacity.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The Intel Arc A380E uses the DG2-128 chip based on Xe-HPG architecture, belonging to the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC. The NVIDIA RTX PRO 4500 uses the GB203 chip based on Blackwell 2.0 architecture, part of the Server Blackwell (Bxx) generation. It is fabricated on a 5 nm process, also at TSMC.

Transistor density differs significantly. The NVIDIA chip packs 45,600 million transistors into a 378 mm² die, achieving 120.6M transistors per mm². The Intel chip contains 7,200 million transistors on a 157 mm² die, at 45.9M transistors per mm². The NVIDIA part is both larger in absolute die size and denser in transistor packing.

Compute resource allocation diverges sharply. The RTX PRO 4500 contains 10496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. The Arc A380E contains 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores, with no tensor core entry recorded. The ratio of shading units favors NVIDIA by 10.25 to 1.

Memory architecture differs by generation and width. The Arc A380E uses GDDR6 memory with a 96-bit bus and 186.0 GB/s bandwidth. The RTX PRO 4500 uses GDDR7 memory with a 256-bit bus and 800.3 GB/s bandwidth. The memory clock also differs: 1937 MHz (15.5 Gbps effective) for Intel, 1563 MHz (25 Gbps effective) for NVIDIA. The newer GDDR7 standard delivers higher effective data rates per clock.

The compute ratio for FP16 operations differs. The Arc A380E achieves 8.192 TFLOPS FP16 with a 2:1 ratio relative to FP32. The RTX PRO 4500 achieves 50.70 TFLOPS FP16 with a 1:1 ratio, meaning it does not halve throughput for half-precision work. This makes the NVIDIA card more efficient for FP16-heavy workloads.

Physical characteristics place them in different chassis categories. The Arc A380E measures 254 mm in length, 127 mm in height, and 20 mm in width. The RTX PRO 4500 measures 267 mm in length, 111 mm in height, and 40 mm in width. Both are single-slot cards, but the NVIDIA part is nearly twice as thick.

Interface and power delivery reflect their intended environments. The Arc A380E uses PCIe 4.0 x8, draws 75 W, and requires no external power connectors. The RTX PRO 4500 uses PCIe 5.0 x16, draws 165 W, and requires one 16-pin connector. The suggested PSU ratings are 250 W for Intel and 450 W for NVIDIA.
