AMD Radeon 8065S vs Intel Arc A380E x2 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results for the AMD Radeon 8065S versus the Intel Arc A380E x2. The database shows zero wins for either part in this specific comparison, and no benchmark scores are listed for either GPU. However, the available specification data allows for a meaningful theoretical comparison based on compute throughput, memory architecture, and power constraints.

The AMD Radeon 8065S delivers 15.36 TFLOPS of FP32 compute, which is 3.75 times the 4.096 TFLOPS offered by the Intel Arc A380E x2. This gap in raw floating-point performance is substantial and indicates that the AMD part should hold a significant advantage in shader-bound workloads, assuming driver efficiency is comparable. The Intel part counters with FP16 throughput of 8.192 TFLOPS, which is double its FP32 rate, while the AMD GPU sustains 15.36 TFLOPS in FP16 as well, reflecting a 1:1 ratio.

Pixel throughput further separates the two. The AMD Radeon 8065S outputs 192.0 GPixel/s, exactly three times the 64.00 GPixel/s of the Intel Arc A380E x2. Texture rate follows a similar pattern: 480.0 GTexel/s versus 128.0 GTexel/s, a 3.75x margin. These ratios match the FP32 disparity, suggesting that the AMD architecture scales uniformly across its execution resources.

Memory bandwidth tells a different story. The Intel Arc A380E x2 uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The AMD Radeon 8065S relies on system-shared memory, with bandwidth listed as system dependent. This makes direct bandwidth comparison impossible from the database, but the AMD part's dependence on shared memory means its effective bandwidth will vary with the host platform's memory configuration, whereas the Intel card has fixed, dedicated bandwidth.

Both GPUs sit at the 50th percentile among all GPUs in the database, indicating that neither is positioned as a high-end part. The AMD Radeon 8065S, despite its higher compute figures, carries a 55 W TDP, while the Intel Arc A380E x2 draws 130 W. This power difference is notable: the AMD part achieves higher peak compute at less than half the power draw, though the Intel card's dedicated memory and PCIe 4.0 x8 interface may offer advantages in latency-sensitive tasks.

Architecture Differences

The AMD Radeon 8065S is built on the RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. It uses the Gorgon Halo chip and belongs to the Navi Mobile (RX 8000M) generation. The die size is 308 mm², and the transistor count is listed as unknown. The Intel Arc A380E x2 uses the Xe-HPG architecture, specifically the DG2-128 chip, fabricated on a 6 nm process, also at TSMC. Its die is 157 mm² with 7,200 million transistors, resulting in a transistor density of 45.9M per mm².

The AMD GPU integrates 2560 shading units, 160 texture mapping units, and 64 render output units. It also includes 40 ray tracing cores. The Intel Arc A380E x2 has 1024 shading units, 64 TMUs, and 32 ROPs, with 8 ray tracing cores. These resource counts align with the compute throughput numbers: AMD has 2.5 times the shading units, 2.5 times the TMUs, and double the ROPs, alongside 5 times the ray tracing cores.

Clock speeds differ sharply. The AMD Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The Intel Arc A380E x2 runs at a fixed 2000 MHz for both base and boost. The AMD part's boost clock is 50% higher than the Intel card's sustained clock, contributing to its higher fill rates and compute figures. Memory clocks are not directly comparable because the AMD GPU uses system-shared memory, while the Intel card runs its GDDR6 at 1937 MHz, or 15.5 Gbps effective.

The AMD Radeon 8065S is an integrated graphics processor with an IGP slot width and no power connectors. It interfaces via PCIe 5.0 x16 and has display outputs that are portable device dependent. The Intel Arc A380E x2 is a single-slot card with a 1x 6-pin power connector, a suggested PSU of 300 W, and PCIe 4.0 x8. It provides 8x mini-DisplayPort 2.0 outputs. The Intel card measures 265 mm in length, 127 mm in height, and 20 mm in width.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity is complete. The production status differs: the AMD Radeon 8065S is active, while the Intel Arc A380E x2 is end-of-life. The AMD part was released on 2025-12-31, and its predecessor is Polaris Mobile. The Intel card launched on 2024-03-31, succeeding Xe Graphics, with Battlemage as its successor.

The Verdict

Benchmark results indicate that the AMD Radeon 8065S should be selected for workloads that demand raw compute throughput and high fill rates. Its 15.36 TFLOPS FP32 performance, 192.0 GPixel/s pixel rate, and 480.0 GTexel/s texture rate place it far ahead of the Intel Arc A380E x2 in shader-heavy applications. The AMD part also offers 40 ray tracing cores versus 8, which suggests superior ray-traced rendering performance, and it does so within a 55 W TDP, making it suitable for power-constrained mobile platforms.

The Intel Arc A380E x2 is the appropriate choice for scenarios that require dedicated memory and fixed bandwidth. Its 6 GB of GDDR6 with 186.0 GB/s bandwidth is not dependent on host system memory, which can be advantageous in multi-GPU or server deployments where memory contention is a concern. The Intel card also provides 8x mini-DisplayPort 2.0 outputs, enabling multi-display configurations that the AMD part cannot match due to its portable device dependent outputs.

The data shows that the AMD Radeon 8065S is the stronger performer on paper, with a 3.75x advantage in FP32 compute and texture rate, and a 3x advantage in pixel rate. However, the Intel Arc A380E x2 remains a viable option for embedded or edge applications where dedicated VRAM and a fixed form factor are priorities. The Intel card's 130 W TDP and single-slot design with a 6-pin connector make it a straightforward drop-in for existing PCIe slots, whereas the AMD GPU's IGP nature limits it to systems with suitable integrated graphics support.

Neither part has recorded benchmark scores or rival comparisons in the database, so real-world performance cannot be confirmed. The specification analysis strongly favors the AMD Radeon 8065S for compute-intensive tasks, while the Intel Arc A380E x2 offers architectural advantages in memory stability and display connectivity.

Specification Differences

The two GPUs differ across nearly every major specification category. The AMD Radeon 8065S uses a 4 nm process with a 308 mm² die, while the Intel Arc A380E x2 uses a 6 nm process with a 157 mm² die and 7,200 million transistors. The AMD part has 2560 shading units, 160 TMUs, and 64 ROPs, compared to 1024, 64, and 32 for the Intel card. Ray tracing cores number 40 versus 8.

Clock behavior is distinct: the AMD GPU runs at 1295 MHz base and 3000 MHz boost, while the Intel card is fixed at 2000 MHz. Memory is the most pronounced difference. The AMD Radeon 8065S uses system-shared memory with system dependent bandwidth, whereas the Intel Arc A380E x2 has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s bandwidth.

Power and physical design differ substantially. The AMD part has a 55 W TDP, an IGP slot width, no power connectors, and a PCIe 5.0 x16 interface. The Intel card has a 130 W TDP, a single-slot design, a 1x 6-pin power connector, a 300 W suggested PSU, and a PCIe 4.0 x8 interface. Display outputs are portable device dependent for AMD, while Intel offers 8x mini-DisplayPort 2.0. Dimensions only exist for the Intel card: 265 mm by 127 mm by 20 mm.

Production status and release timing also differ. The AMD Radeon 8065S is active and released on 2025-12-31, with Polaris Mobile as its predecessor. The Intel Arc A380E x2 is end-of-life, released on 2024-03-31, with Xe Graphics as predecessor and Battlemage as successor.
