AMD Radeon PRO W7900 vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the AMD Radeon PRO W7900 and the Intel Arc A380E. The AMD Radeon PRO W7900 delivers an average benchmark score of 110,725, while the Intel Arc A380E has no recorded benchmarks in the database, resulting in an average score of zero. This places the AMD part in the 94th percentile of all GPUs, whereas the Intel Arc A380E sits in the 50th percentile.

In Geekbench OpenCL, the AMD Radeon PRO W7900 scores 84,379 points. In Geekbench Vulkan, it reaches 137,070 points. The Intel Arc A380E has no entries for either test, leaving direct comparison impossible from the available data. Instead, the nearest rivals for the AMD card provide context: the NVIDIA Tesla V100 SXM2 16 GB scores 114,395, which is 3.2% higher than the Radeon PRO W7900's average. The NVIDIA RTX A5500 Mobile scores 113,944, 2.8% higher. The AMD Radeon Pro Vega II scores 109,617, just 1% below the W7900. The AMD Radeon Pro W6600X scores 107,342, which is 3.2% lower than the W7900.

The FP32 compute figures reinforce the hierarchy. The AMD Radeon PRO W7900 delivers 61.32 TFLOPS of FP32 performance, while the Intel Arc A380E delivers 4.096 TFLOPS. That is a difference of roughly 15 times in raw single-precision throughput. Memory bandwidth follows the same pattern: the AMD card offers 864.0 GB/s across a 384-bit bus with 48 GB of GDDR6, while the Intel card offers 186.0 GB/s across a 96-bit bus with 6 GB of GDDR6. The pixel rate for the AMD card is 479.0 GPixel/s versus 64.00 GPixel/s for the Intel card. Texture rate is 958.1 GTexel/s versus 128.0 GTexel/s.

The Intel Arc A380E does have one advantage in the specifications: its FP16 rate of 8.192 TFLOPS is double its FP32 rate, indicating a 2:1 ratio, whereas the AMD card's FP16 rate equals its FP32 rate at 61.32 TFLOPS (1:1). For workloads that can use FP16 instructions, the Intel architecture provides relatively more throughput per FP32 unit, but the absolute numbers still favor the AMD card overwhelmingly.

The Verdict

The data indicates that the AMD Radeon PRO W7900 is the clear choice for any workload requiring high compute throughput, large memory capacity, or wide memory bandwidth. Its 48 GB frame buffer and 864.0 GB/s bandwidth are suited for massive datasets, while its 61.32 TFLOPS FP32 performance handles demanding simulation, rendering, or machine learning inference tasks. The 94th percentile ranking among all GPUs confirms its position as a high-end workstation part.

The Intel Arc A380E, with no recorded benchmarks and a 50th percentile ranking, serves a different purpose entirely. Its 75 W power draw, single-slot design, and lack of power connectors make it suitable for compact or power-constrained systems. Its 6 GB memory and 4.096 TFLOPS FP32 performance are modest by comparison. The production status is listed as end-of-life, with the successor being Battlemage.

From the data alone, the AMD Radeon PRO W7900 is the appropriate pick for users whose applications demand maximum compute resources. The Intel Arc A380E is appropriate only for scenarios where the 75 W power envelope, single-slot footprint, or 250 W suggested PSU rating are the binding constraints. The absence of benchmark scores for the Intel card means its real-world performance cannot be verified from the database, which further weakens its case for compute-intensive use.

Specification Differences

The two cards differ across nearly every specification. The AMD Radeon PRO W7900 uses the Navi 31 chip with RDNA 3.0 architecture and the Plum Bonito codename, fabricated on a 5 nm process at TSMC. The Intel Arc A380E uses the DG2-128 chip with Xe-HPG architecture, fabricated on a 6 nm process at TSMC. Transistor counts differ substantially: 57,700 million for the AMD card versus 7,200 million for the Intel card. Die size is 529 mm² for AMD versus 157 mm² for Intel, yielding transistor densities of 109.1M per mm² and 45.9M per mm² respectively.

Memory configurations are far apart. The AMD card has 48 GB of GDDR6 on a 384-bit bus with 864.0 GB/s bandwidth. The Intel card has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth. Clock speeds differ as well: the AMD card has a base clock of 1760 MHz and a boost of 2495 MHz, while the Intel card has a fixed 2000 MHz base and boost. Memory clocks are 2250 MHz (18 Gbps effective) for AMD and 1937 MHz (15.5 Gbps effective) for Intel.

Core counts show the AMD card's scale advantage: 6144 shading units, 384 TMUs, 192 ROPs, and 96 RT cores. The Intel card has 1024 shading units, 64 TMUs, 32 ROPs, and 8 RT cores. The AMD card's pixel rate is 479.0 GPixel/s and texture rate is 958.1 GTexel/s, compared to 64.00 GPixel/s and 128.0 GTexel/s for Intel.

Physical specifications differ too. The AMD card is triple-slot, 280 mm long, 110 mm tall, and 51 mm wide, with a 295 W TDP. The Intel card is single-slot, 254 mm long, 127 mm tall, and 20 mm wide, with a 75 W TDP. The AMD card uses PCIe 4.0 x16, while the Intel card uses PCIe 4.0 x8. Display outputs: the AMD card has 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, while the Intel card has 4x DisplayPort 2.0. The AMD card launched with an MSRP of 3,999 USD on 2023-05-25; the Intel card has no recorded launch MSRP and released on 2024-03-31.

Architecture Differences

The architectural split is between RDNA 3.0 and Xe-HPG. AMD's RDNA 3.0, used in the Radeon PRO W7900, is a 5 nm design with 57,700 million transistors packed into 529 mm². The Intel Arc A380E uses Xe-HPG on a 6 nm process with 7,200 million transistors in 157 mm². Both architectures support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API surface is identical.

The AMD card's FP32 and FP16 rates are identical at 61.32 TFLOPS, indicating a 1:1 ratio. The Intel card's FP16 rate of 8.192 TFLOPS is double its FP32 rate of 4.096 TFLOPS, indicating a 2:1 ratio. This means the Intel architecture dedicates more hardware to half-precision operations relative to single-precision, while the AMD architecture provides equal throughput across both.

Ray tracing hardware is present in both cards: 96 RT cores for AMD versus 8 RT cores for Intel. The AMD card also has 192 ROPs, which drive its 479.0 GPixel/s pixel fill rate, versus 32 ROPs for Intel's 64.00 GPixel/s. Texture units number 384 for AMD and 64 for Intel, producing the respective texture rates.

The AMD card's predecessor is the Radeon Pro Vega, while the Intel card's predecessor is Xe Graphics and its successor is Battlemage. The AMD card is still active in production; the Intel card is end-of-life. The AMD card's codename is Plum Bonito, and it belongs to the Radeon Pro Navi (Navi III Series) generation. The Intel card belongs to the Alchemist (Arc 3) generation.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every measured or specified performance category. Its 61.32 TFLOPS FP32 compute is suited for heavy simulation, scientific computing, and large-scale rendering. Its 48 GB memory capacity and 864.0 GB/s bandwidth handle datasets that would exceed the Intel card's 6 GB frame buffer by a wide margin. The 94th percentile ranking among all GPUs positions it alongside high-end workstation accelerators, with nearest rivals within a few percentage points in either direction.

The Intel Arc A380E wins in power efficiency and physical footprint. Its 75 W TDP requires no auxiliary power connectors, and its single-slot design at 254 mm length, 127 mm height, and 20 mm width allows installation in compact chassis. The 250 W suggested PSU is far below the 600 W suggested for the AMD card. For systems where power draw, space, or thermal limits are the primary constraints, the Intel card is the only viable option between the two.

The FP16 ratio difference gives the Intel card a relative advantage in workloads that use half-precision arithmetic exclusively, since it provides 2:1 FP16 throughput versus the AMD card's 1:1 ratio. However, the AMD card's absolute FP16 throughput of 61.32 TFLOPS still dwarfs the Intel card's 8.192 TFLOPS.

The AMD card's active production status and later predecessor (Radeon Pro Vega) indicate ongoing availability, while the Intel card's end-of-life status and successor (Battlemage) suggest it is being phased out. The AMD card's launch MSRP of 3,999 USD reflects its workstation positioning, while the Intel card has no recorded launch MSRP.

The data makes the division clear: the AMD Radeon PRO W7900 is for compute-intensive professional workloads with large memory requirements. The Intel Arc A380E is for low-power, space-constrained deployments where benchmark performance is not the deciding factor.
