Architecture Differences

The AMD Radeon PRO W7800 and Intel Arc A380E represent fundamentally different design philosophies and target segments. The Radeon PRO W7800 is built on the Navi 31 chip using TSMC’s 5 nm process, packing 57,700 million transistors into a 529 mm² die. This yields a transistor density of 109.1 million per square millimeter. The Intel Arc A380E uses the DG2-128 chip on TSMC’s 6 nm process, with 7,200 million transistors on a 157 mm² die, giving a density of 45.9 million per square millimeter. The AMD chip is roughly eight times larger in die area and contains eight times more transistors.

The architectural generations differ significantly. The Radeon PRO W7800 belongs to the Radeon Pro Navi (Navi III Series) generation with RDNA 3.0 architecture, codenamed Plum Bonito. The Arc A380E belongs to the Alchemist (Arc 3) generation with Xe-HPG architecture. These are distinct GPU designs with no shared IP between them.

Compute resources diverge sharply. The Radeon PRO W7800 contains 4,480 shading units, 280 texture mapping units, 128 render output units, and 70 ray tracing cores. The Arc A380E has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The AMD card has over four times the shader count, over four times the TMU count, four times the ROP count, and nearly nine times the ray tracing core count.

Clock behavior also differs. The Radeon PRO W7800 operates at a base clock of 1895 MHz and boosts to 2525 MHz. The Arc A380E runs at a fixed 2000 MHz for both base and boost, indicating a locked clock design typical of low-power embedded or edge products. Memory clocks follow a similar pattern: the AMD card runs memory at 2250 MHz with 18 Gbps effective, while Intel’s runs at 1937 MHz with 15.5 Gbps effective.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists. The bus interfaces differ, with the Radeon PRO W7800 using PCIe 4.0 x16 and the Arc A380E using PCIe 4.0 x8, halving the available host bandwidth for the Intel part.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Radeon PRO W7800 and the Intel Arc A380E. However, the Radeon PRO W7800 has recorded scores in two tests, while the Arc A380E has no benchmark data. The Radeon PRO W7800 scores 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan, producing an average benchmark score of 164,894.

For context on the Radeon PRO W7800’s standing, the database lists its nearest rivals. The NVIDIA RTX 4500 Ada Generation scores 166,094, which is 0.7% higher than the Radeon PRO W7800. The NVIDIA RTX A5500 scores 165,217, a margin of 0.2% higher. The AMD Radeon Pro W6900X scores 168,574, 2.2% higher. The NVIDIA A100 PCIe 40 GB scores 162,504, which is 1.5% lower than the Radeon PRO W7800. These margins show the Radeon PRO W7800 sits firmly in a competitive band among professional workstation GPUs, neither leading nor trailing by more than a few percentage points.

The Arc A380E has no recorded benchmark scores, no nearest rival data, and an average benchmark score of zero. Its 50th percentile ranking indicates it sits at the median of all GPUs in the database, but without measurable scores, the database cannot quantify its performance against the Radeon PRO W7800. The head-to-head wins counter shows zero wins for both cards, reflecting the absence of directly comparable test data.

Where Each One Wins

The AMD Radeon PRO W7800 wins decisively in raw compute performance, memory capacity, memory bandwidth, and rendering throughput. Its 45.25 TFLOPS FP32 and 90.50 TFLOPS FP16 figures place it in an entirely different performance class from the Arc A380E’s 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16. The pixel rate of 323.2 GPixel/s versus 64.00 GPixel/s and texture rate of 707.0 GTexel/s versus 128.0 GTexel/s indicate the AMD card can handle far heavier rasterization and texture workloads. The 32 GB memory with 576.0 GB/s bandwidth supports large datasets, high-resolution textures, and multi-GPU rendering scenarios that the 6 GB, 186.0 GB/s configuration on the Intel part cannot accommodate.

The Radeon PRO W7800 also wins on interface bandwidth with PCIe 4.0 x16 versus x8, and it delivers more display outputs with higher version support (DisplayPort 2.1 versus 2.0). Its 97th percentile ranking versus the Arc A380E’s 50th percentile confirms its position as a high-end professional workstation part. The nearest rival data shows the Radeon PRO W7800 trading places within 2.2% of several top-tier NVIDIA and AMD workstation cards, confirming its competitiveness in that segment.

The Intel Arc A380E wins in power efficiency and physical footprint. Its 75 W TDP requires no external power connectors and a suggested 250 W power supply, compared to the Radeon PRO W7800’s 260 W TDP, dual 8-pin connectors, and 600 W suggested supply. The Arc A380E is single-slot with dimensions of 254 mm x 127 mm x 20 mm, versus the Radeon’s dual-slot 280 mm x 110 mm x 40 mm. This makes the Intel card suitable for space-constrained systems or passively cooled embedded applications where the AMD card would not fit or would require substantial power delivery infrastructure.

The Arc A380E also has a higher base clock (2000 MHz versus 1895 MHz), though its boost clock equals its base clock, meaning no dynamic overclocking headroom. Its four DisplayPort 2.0 outputs match the Radeon’s output count but lack the mini-DisplayPort option. The Arc A380E’s pin count of 1024 shading units and 8 ray tracing cores still provides entry-level ray tracing capability, and its 64.00 GPixel/s pixel rate is adequate for lower-resolution or lower-frame-rate professional visualization tasks.

The production statuses differ meaningfully. The Radeon PRO W7800 remains active with a successor not yet listed, while the Arc A380E is end-of-life with Battlemage listed as its successor. The Radeon PRO W7800 has a launch MSRP of 2,499 USD, while the Arc A380E has no recorded launch MSRP in the database.

For workloads demanding maximum compute, memory capacity, and rendering throughput, the Radeon PRO W7800 is the clear choice. For deployments prioritizing low power draw, minimal physical footprint, and simple power delivery, the Arc A380E serves that niche. The benchmark data shows no directly comparable test results, so the performance gap must be inferred from the specification deltas and the Radeon PRO W7800’s percentile standing among all GPUs.
