AMD Radeon PRO W7900D vs Intel Arc A380E x2 Comparison

The Verdict

The database places both the AMD Radeon PRO W7900D and the Intel Arc A380E x2 at the 50th percentile versus all GPUs, with no recorded benchmark wins for either side. This parity in percentile ranking, however, masks a stark divergence in intended use cases. The AMD Radeon PRO W7900D targets heavy compute and high-resolution rendering workloads, while the Intel Arc A380E x2, with its dual-card configuration, suits multi-display and low-power embedded applications. The recorded data shows no benchmark wins for either product, so the decision rests entirely on architectural fit and system requirements. Choose the AMD card for maximum single-GPU throughput and expansive memory capacity; choose the Intel dual-card setup for compact, multi-output deployments where power draw is a primary constraint.

Architecture Differences

The AMD Radeon PRO W7900D uses the Navi 31 chip built on RDNA 3.0 architecture, codenamed Plum Bonito. This is a 5 nm TSMC design containing 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The Intel Arc A380E x2 uses the DG2-128 chip based on Xe-HPG architecture, from the Alchemist generation (Arc 3). It is a 6 nm TSMC part with 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9 million per square millimeter. The AMD chip packs 6,144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The Intel configuration, representing two cards, provides 1,024 shading units per card, 64 TMUs, 32 ROPs, and 8 RT cores per card.

Clock behavior differs notably. The AMD card runs at a 1327 MHz base and boosts to 2156 MHz, while the Intel card operates at a fixed 2000 MHz for both base and boost. Memory architecture is vastly different. The AMD card carries 48 GB of GDDR6 across a 384-bit bus, producing 864.0 GB/s of bandwidth. The Intel card carries 6 GB of GDDR6 on a 96-bit bus per card, delivering 186.0 GB/s per card. The AMD memory runs at 2250 MHz (18 Gbps effective); the Intel memory runs at 1937 MHz (15.5 Gbps effective).

Compute rates show the scale of the gap. The AMD card reaches 52.99 TFLOPS FP32 and the same 52.99 TFLOPS FP16 with a 1:1 ratio. The Intel card reaches 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16 with a 2:1 ratio. Pixel rate for AMD is 414.0 GPixel/s versus 64.00 GPixel/s for Intel. Texture rate is 827.9 GTexel/s versus 128.0 GTexel/s.

Power and physical specifications separate the two further. The AMD Radeon PRO W7900D draws 295 W, requires a 600 W suggested power supply, uses two 8-pin connectors, and occupies a triple-slot width. The Intel Arc A380E x2 draws 130 W per card, suggests a 300 W power supply, uses a single 6-pin connector per card, and fits a single-slot width. Both support PCIe 4.0, but AMD uses x16 while Intel uses x8. The AMD card measures 280 mm in length, 110 mm in height, and 51 mm in width. The Intel card measures 265 mm in length, 127 mm in height, and 20 mm in width. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: AMD provides 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1; the Intel dual-card setup provides 8x mini-DisplayPort 2.0 total.

Where Each One Wins

The recorded data shows no direct benchmark wins for either product. The architectural figures, however, define clear dominance zones. The AMD Radeon PRO W7900D wins in raw compute, memory bandwidth, pixel throughput, and texture throughput. Its 52.99 TFLOPS FP32 output, 864.0 GB/s bandwidth, and 414.0 GPixel/s pixel rate position it for 3D rendering, simulation, and AI training workloads that demand large memory frames and high arithmetic throughput. The 48 GB memory capacity supports massive datasets without swapping.

The Intel Arc A380E x2 wins in power efficiency per card, physical footprint, and display output quantity. Each card draws 130 W versus 295 W, fits a single slot, and the pair delivers eight mini-DisplayPort 2.0 outputs. This suits digital signage, video walls, and multi-monitor control rooms where many independent displays are required. The fixed 2000 MHz clock across base and boost simplifies thermal management. The dual-card configuration also offers redundancy in multi-display setups, since each card operates independently.

Neither product shows a benchmark advantage in the database. The separation is functional, not competitive. AMD leads in per-card capability; Intel leads in deployment flexibility and output density.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results and zero wins for either product. This absence of measured data is itself informative. The two cards share the 50th percentile ranking, but that ranking reflects different populations and use cases. The AMD Radeon PRO W7900D is a workstation-class accelerator with 52.99 TFLOPS FP32 and 52.99 TFLOPS FP16. The Intel Arc A380E x2 is an embedded-class dual-card solution with 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16 per card. Even with two cards, the Intel configuration cannot match the AMD card in raw arithmetic throughput.

Memory bandwidth tells a similar story. The AMD card's 864.0 GB/s dwarfs the Intel card's 186.0 GB/s per card. Doubling the Intel cards would yield approximately 372.0 GB/s combined, still far below AMD's figure. The AMD card also offers 48 GB of memory versus 6 GB per Intel card. For workloads that fit within a single GPU's memory pool, the AMD card avoids the overhead of multi-GPU data distribution.

The Intel advantage lies in power and output density. Each Intel card draws 130 W, and the dual-card setup totals 260 W, less than the AMD card's 295 W. The Intel pair provides 8x mini-DisplayPort 2.0 outputs versus AMD's 4 outputs. The Intel cards use a single 6-pin connector each, while AMD requires two 8-pin connectors. The Intel cards are single-slot, 20 mm wide, while AMD is triple-slot, 51 mm wide. These physical differences matter in rack-mounted or space-constrained environments.

Pixel and texture rates reinforce AMD's dominance in rasterization-heavy tasks. AMD's 414.0 GPixel/s and 827.9 GTexel/s compare to Intel's 64.00 GPixel/s and 128.0 GTexel/s per card. The AMD card also boosts to 2156 MHz versus Intel's fixed 2000 MHz. The AMD card uses a 384-bit memory bus; Intel uses 96-bit per card. The AMD card's transistor count of 57,700 million versus Intel's 7,200 million reflects the scale of the silicon investment.
