AMD Radeon 8065S vs Intel Arc A380E Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the AMD Radeon 8065S or the Intel Arc A380E. Both entries show an average benchmark score of zero and list no head-to-head results. The percentile ranking for both products sits at 50, placing them exactly at the midpoint of all GPUs in the database. This absence of measured performance data means the comparison must rely entirely on architectural specifications and the derived throughput figures recorded in the database.

The raw compute numbers show a wide gulf between the two. The AMD Radeon 8065S delivers 15.36 TFLOPS of FP32 performance, while the Intel Arc A380E produces 4.096 TFLOPS. That places the AMD part at 3.75 times the raw single-precision throughput of the Intel part. The FP16 comparison shifts slightly: the AMD part maintains a 1:1 ratio at 15.36 TFLOPS, while the Intel part doubles its rate to 8.192 TFLOPS using a 2:1 ratio. Even at FP16, the AMD part remains ahead by 1.875 times.

Pixel throughput follows the same pattern. The AMD Radeon 8065S records 192.0 GPixel/s, exactly three times the 64.00 GPixel/s of the Intel Arc A380E. Texture rate shows a similar 3.75 to 1 advantage for AMD: 480.0 GTexel/s versus 128.0 GTexel/s. These derived figures indicate that, in any workload limited by pixel fill or texture fetch, the AMD part would complete roughly three to four times as much work per unit time.

Memory bandwidth tells a different story, but one that still favors AMD. The Intel Arc A380E uses dedicated 6 GB of GDDR6 on a 96-bit bus, achieving 186.0 GB/s. The AMD Radeon 8065S uses system shared memory, with bandwidth listed as system dependent and no fixed figure recorded. The database provides no comparable bandwidth number for the AMD part, so the Intel card holds the only concrete memory bandwidth specification in the comparison.

Clock speeds show Intel with a higher fixed operating point. The Arc A380E runs at a flat 2000 MHz base and boost. The AMD Radeon 8065S has a 1295 MHz base clock but boosts to 3000 MHz. The AMD part's boost clock is 50% higher than Intel's constant 2000 MHz, though the base clock sits 35.25% lower. The gap between AMD's base and boost clocks suggests substantial dynamic range in power management.

Architecture Differences

The two GPUs come from different architectural families entirely. The AMD Radeon 8065S uses the Gorgon Halo chip built on RDNA 3.5, part of the Navi Mobile (RX 8000M) generation. The Intel Arc A380E uses the DG2-128 chip on Xe-HPG, from the Alchemist (Arc 3) generation. These are not incremental revisions of a shared design; they are separate approaches to GPU computing.

Process technology favors AMD. The Radeon 8065S is fabricated on a 4 nm process at TSMC. The Arc A380E uses a 6 nm process, also at TSMC. Smaller process geometry typically allows higher transistor density and better power efficiency, though the database lists the AMD transistor count as unknown. Intel's part has 7,200 million transistors on a 157 mm² die, yielding a density of 45.9 million transistors per square millimeter. The AMD die measures 308 mm², nearly double the Intel die area, but its transistor count is not recorded.

Compute resource allocation diverges sharply. The AMD Radeon 8065S has 2560 shading units, 160 texture mapping units, and 64 raster operation units. The Intel Arc A380E has 1024 shading units, 64 TMUs, and 32 ROPs. AMD's part doubles Intel's shading units, TMUs, and ROPs. Ray tracing hardware shows an even larger gap: 40 RT cores on the AMD part versus 8 on the Intel part, a five to one ratio.

Memory architecture differs fundamentally. The AMD Radeon 8065S has no dedicated VRAM; all memory is system shared, with the bus width and type also listed as system shared. The Intel Arc A380E has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s of bandwidth. This means the AMD part's memory performance depends entirely on the host system, while Intel's card has fixed, predictable memory characteristics.

Power and physical design contrast sharply. The AMD Radeon 8065S draws 55 W and is an integrated graphics processor (IGP) with no power connectors and a portable device dependent display output. The Intel Arc A380E draws 75 W, is a single-slot card with no power connectors, uses a PCIe 4.0 x8 interface, and has four DisplayPort 2.0 outputs. The Intel card measures 254 mm in length, 127 mm in height, and 20 mm in width. The AMD part has no recorded dimensions because it is integrated into a portable device.

The bus interface also differs: the AMD part uses PCIe 5.0 x16, while the Intel card uses PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The Verdict

The recorded data shows two products with different intended roles. The AMD Radeon 8065S carries 3.75 times the FP32 throughput, three times the pixel rate, 3.75 times the texture rate, and five times the ray tracing cores compared to the Intel Arc A380E. Its 3000 MHz boost clock exceeds Intel's 2000 MHz by 50%. The AMD part also uses a smaller 4 nm process node and a newer architecture generation, RDNA 3.5 versus Xe-HPG.

The Intel Arc A380E holds advantages in the few categories where it has recorded figures. It has a fixed 6 GB GDDR6 memory configuration with 186.0 GB/s of bandwidth, whereas AMD's memory performance is system dependent. Intel's base clock of 2000 MHz is higher than AMD's 1295 MHz base. The Intel card is a standalone single-slot solution with four DisplayPort 2.0 outputs, while the AMD part is an integrated GPU with portable device dependent display outputs. The Intel part is also end-of-life, with Battlemage listed as its successor, while the AMD part remains active in production.

For workloads that rely on fixed memory bandwidth and predictable standalone operation, the Intel Arc A380E offers a concrete, self-contained specification. For any workload that scales with shading units, texture rate, pixel fill, or ray tracing cores, the AMD Radeon 8065S dominates by a wide margin. The database records no direct benchmark wins for either product, so the verdict rests on the architectural and throughput data alone.

Where Each One Wins

The AMD Radeon 8065S wins in every compute throughput category recorded in the database. Its 2560 shading units, 160 TMUs, and 64 ROPs double the corresponding resources on the Intel Arc A380E. The FP32 rate of 15.36 TFLOPS versus 4.096 TFLOPS indicates a 3.75 times advantage in general compute workloads. The 480.0 GTexel/s texture rate versus 128.0 GTexel/s suggests a similar advantage in texture-bound rendering. The 192.0 GPixel/s pixel rate versus 64.00 GPixel/s indicates three times the fill rate for rasterization-heavy scenes. The 40 RT cores versus 8 suggest a substantial edge in ray-traced effects, though no benchmark data confirms real-world scaling.

The Intel Arc A380E wins where fixed, dedicated resources matter. Its 6 GB GDDR6 memory with 186.0 GB/s bandwidth provides a known, constant memory subsystem, while the AMD part's bandwidth is system dependent and unquantified. The Intel card's 2000 MHz base clock is higher than AMD's 1295 MHz base, which could favor sustained workloads that do not trigger boost behavior. The four DisplayPort 2.0 outputs give the Intel card a defined multi-monitor capability, whereas the AMD part's display outputs are portable device dependent. The Intel card's single-slot form factor and 254 mm length make it a drop-in standalone component, while the AMD part is an IGP with no physical dimensions recorded.

For users with a portable device that already integrates the AMD Radeon 8065S, the data shows a part with dominant compute resources and a high 3000 MHz boost clock. For users assembling a standalone system with a PCIe 4.0 x8 slot, the Intel Arc A380E offers a complete, self-contained package with dedicated memory and fixed display outputs.

The two GPUs share identical API support (DirectX 12 Ultimate 12_2, OpenGL 4.6, Vulkan 1.4) and both lack tensor cores in the recorded data. The AMD part uses a newer process node, a larger die, and a later release date. The Intel part has a fully specified memory subsystem, a defined physical footprint, and a listed successor.
