AMD Radeon RX 9050 vs Intel Arc A380M Comparison

The Verdict

The AMD Radeon RX 9050 and Intel Arc A380M are both 50th percentile GPUs in the database, yet they serve entirely different segments. The RX 9050 is a desktop-oriented, dual-slot board with a 92 W TDP and PCIe 5.0 x16 interface, designed for a full-size build with an 8-pin power connector. The Arc A380M is a 35 W MXM module for portable devices, with no power connector and no fixed display outputs. The data shows that the RX 9050 targets a user with a standard desktop chassis and a 250 W suggested PSU, while the A380M fits a compact, low-power mobile chassis where the display path is determined by the host system. The RX 9050 is the choice for anyone who needs a discrete desktop card with standard outputs and a conventional power delivery path. The A380M is the choice for an embedded or laptop-style platform where board size and power draw are the primary constraints.

Architecture Differences

The RX 9050 uses the Navi 44 chip built on RDNA 4.0 architecture, fabricated on a 4 nm TSMC process. It packs 29,700 million transistors into a 199 mm² die, yielding a transistor density of 149.2 million per mm². The Arc A380M uses the DG2-128 chip with Xe-HPG architecture, built on a 6 nm TSMC process. It contains 7,200 million transistors on a 157 mm² die, for a density of 45.9 million per mm². The RX 9050 is the newer design, released on 2026-07-27, while the A380M launched on 2023-01-23. The RX 9050 is part of the Navi IV (RX 9000) generation, succeeding the Navi III line. The A380M belongs to the Alchemist (Arc 3 Mobile) generation.

The two differ in memory architecture. The RX 9050 uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The A380M uses 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The RX 9050 has a 128-bit bus width, which is 32 bits wider than the A380M's 96-bit bus. Memory clock speeds also differ: the RX 9050 runs at 2250 MHz (18 Gbps effective), while the A380M runs at 1937 MHz (15.5 Gbps effective). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical.

Shader and compute resources differ in several ways. Both have 1024 shading units and 64 TMUs, but the RX 9050 has 64 ROPs, double the A380M's 32 ROPs. The RX 9050 also has 16 ray tracing cores, while the A380M has 8. Clock behavior is distinct: the RX 9050 has a base clock of 1330 MHz, a boost of 2600 MHz, and a game clock of 1920 MHz. The A380M has a base of 1550 MHz and a boost of 2000 MHz, with no game clock listed. The RX 9050 has the higher boost clock by 600 MHz, which contributes to its large compute advantage.

Where Each One Wins

The RX 9050 wins in every raw compute category recorded in the database. Its FP32 throughput is 10.65 TFLOPS, while the A380M delivers 4.096 TFLOPS. In FP16, the RX 9050 also delivers 10.65 TFLOPS with a 1:1 ratio, while the A380M reaches 8.192 TFLOPS with a 2:1 ratio. The RX 9050 has a 2.6x advantage in FP32 and roughly a 1.3x advantage in FP16. Pixel fill rate strongly favors the RX 9050: it produces 166.4 GPixel/s versus 64.00 GPixel/s for the A380M. Texture fill rate also favors the RX 9050 at 166.4 GTexel/s versus 128.0 GTexel/s.

The A380M wins in power efficiency and physical flexibility. Its 35 W TDP is less than half the RX 9050's 92 W. That lower power envelope makes it suitable for MXM-A (3.1) slots in portable devices, and its display outputs are listed as "Portable Device Dependent," meaning the host system controls the display path. The RX 9050 requires an 8-pin power connector and a 250 W suggested PSU, which is normal for a desktop card but excludes it from compact mobile platforms.

The RX 9050 uses a PCIe 5.0 x16 bus interface, which provides ample bandwidth for its 288.0 GB/s memory. The A380M uses MXM-A (3.1), a modular interface designed for laptops and small form factor systems. The RX 9050 has explicit display outputs (1x HDMI 2.1b, 2x DisplayPort 2.1a), while the A380M has none of its own. For a desktop user, the RX 9050 is the clear pick. For a system integrator working with MXM-based mobile hardware, the A380M is the only one that fits.

FAQ

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark entries, but the specification sheet provides decisive comparisons. The biggest single-win metric for the RX 9050 is pixel fill rate. At 166.4 GPixel/s, it is 2.6x the A380M's 64.00 GPixel/s. That difference comes from the RX 9050 having 64 ROPs versus 32 ROPs, combined with a higher boost clock of 2600 MHz versus 2000 MHz. In practical terms, rasterization-bound workloads that depend on fill rate will show a substantial advantage for the RX 9050.

FP32 compute is the next largest gap. The RX 9050's 10.65 TFLOPS is 2.6x the A380M's 4.096 TFLOPS. This matters for general shader workloads, physics simulation, and any compute-heavy game effects. The RX 9050's advantage in FP16 is smaller but still clear: 10.65 TFLOPS versus 8.192 TFLOPS, a 1.3x lead. The RX 9050 uses a 1:1 FP16 ratio, meaning it processes FP16 at the same rate as FP32. The A380M uses a 2:1 ratio, so its FP16 throughput is double its FP32 throughput. For workloads that rely on FP16, the A380M is comparatively stronger than its FP32 number suggests, but it still loses to the RX 9050.

Memory bandwidth favors the RX 9050 by 102.0 GB/s, or roughly 1.5x. The 288.0 GB/s versus 186.0 GB/s difference stems from the wider 128-bit bus and the higher 18 Gbps effective memory speed versus 15.5 Gbps. Texture fill rate also favors the RX 9050, at 166.4 GTexel/s versus 128.0 GTexel/s, a 1.3x lead. Both GPUs have 64 TMUs, so the texture rate difference comes purely from clock speed: the RX 9050's 2600 MHz boost versus the A380M's 2000 MHz boost.

The A380M has no wins in compute, fill rate, or memory throughput. Its advantages are structural: a 35 W TDP that is 57 W lower than the RX 9050's 92 W, and a form factor that fits MXM-A (3.1) slots. The A380M also has a higher base clock at 1550 MHz versus 1330 MHz, but that does not translate into a performance win because the RX 9050's boost and game clocks are far higher.
