AMD Radeon RX 9050 vs Intel Arc A380E Comparison

The Verdict

The AMD Radeon RX 9050 is the clear performance leader based on the recorded specifications, delivering more than double the raw compute throughput of the Intel Arc A380E. The RX 9050 achieves 10.65 TFLOPS FP32 against 4.096 TFLOPS for the A380E, a 2.6x advantage that carries through every major rendering metric. The A380E counters with lower power draw, a single-slot profile, and no external power connector, making it the choice for compact or power-constrained systems where absolute performance is secondary.

For users prioritizing frame rates and rendering throughput, the RX 9050 is the only option that makes sense. Its 288.0 GB/s memory bandwidth versus 186.0 GB/s, 64 ROPs versus 32, and 16 ray tracing cores versus 8 create a decisive gap. The A380E serves a narrower role: it fits where the RX 9050 physically cannot, such as systems limited to single-slot cards or those lacking auxiliary power headers. The data shows no scenario where the A380E wins on raw capability; its advantages are entirely physical and electrical.

Architecture Differences

The two GPUs come from different architectural families and manufacturing processes. The RX 9050 uses the Navi 44 chip built on RDNA 4.0 architecture, fabricated at TSMC's 4 nm node. The A380E uses the DG2-128 chip based on Xe-HPG architecture, fabricated at TSMC's 6 nm node. The RX 9050 packs 29,700 million transistors into a 199 mm² die, yielding a transistor density of 149.2 million per mm². The A380E contains 7,200 million transistors across 157 mm², for a density of 45.9 million per mm².

Both GPUs feature 1024 shading units and 64 texture mapping units, but the similarities end there. The RX 9050 has 64 ROPs, while the A380E has 32. Ray tracing hardware differs substantially: the RX 9050 includes 16 RT cores, the A380E has 8. The RX 9050 runs FP16 at a 1:1 ratio with FP32, both at 10.65 TFLOPS. The A380E runs FP16 at a 2:1 ratio, delivering 8.192 TFLOPS FP16 against its 4.096 TFLOPS FP32. This means the A380E's FP16 throughput is 77% of the RX 9050's, a smaller gap than the FP32 comparison suggests.

Memory architecture diverges as well. The RX 9050 uses 8 GB GDDR6 on a 128-bit bus, producing 288.0 GB/s bandwidth. The A380E uses 6 GB GDDR6 on a 96-bit bus, limited to 186.0 GB/s. Clock behavior also differs: the RX 9050 has a 1330 MHz base clock and 2600 MHz boost, while the A380E sits at a flat 2000 MHz for both base and boost. The RX 9050's memory runs at 2250 MHz (18 Gbps effective), the A380E's at 1937 MHz (15.5 Gbps effective).

Where Each One Wins

The RX 9050 wins every compute and rendering category recorded in the database. Its pixel rate of 166.4 GPixel/s is 2.6x the A380E's 64.00 GPixel/s. Its texture rate of 166.4 GTexel/s compares to 128.0 GTexel/s for the A380E, a 1.3x lead. FP32 throughput favors the RX 9050 by 2.6x, and even in FP16, where the A380E's 2:1 ratio helps, the RX 9050 still leads by 1.3x.

The A380E wins in physical and electrical categories. It draws 75 W versus 92 W for the RX 9050, a 17 W difference. It occupies a single slot against the RX 9050's dual-slot design. The A380E requires no power connectors, while the RX 9050 needs a single 8-pin connector. Both list a 250 W suggested PSU, so system power supply requirements remain identical. The A380E also offers four DisplayPort 2.0 outputs, while the RX 9050 provides one HDMI 2.1b and two DisplayPort 2.1a ports. The A380E's 254 mm length, 127 mm height, and 20 mm width define a compact card, though the RX 9050's dimensions are not recorded in the database.

For ray tracing workloads, the RX 9050's 16 RT cores double the A380E's 8. The RX 9050 also uses PCIe 5.0 x16, versus PCIe 4.0 x8 for the A380E, which doubles both the bus generation and lane count. The RX 9050's production status is Active, while the A380E is marked End-of-life with a Battlemage successor already designated. The RX 9050 released on 2026-07-27, over two years after the A380E's 2024-03-31 launch.

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for either GPU, but the specification differences establish clear performance deltas. The most significant gap appears in pixel throughput. The RX 9050 renders at 166.4 GPixel/s, exactly 2.6 times the A380E's 64.00 GPixel/s. This affects fill-rate-bound scenes, where the RX 9050 can push more pixels per frame at high resolutions.

Texture throughput favors the RX 9050 by a smaller margin. At 166.4 GTexel/s versus 128.0 GTexel/s, the RX 9050 holds a 1.3x lead. Both cards share 64 TMUs, so the difference comes from the RX 9050's higher boost clock (2600 MHz versus 2000 MHz). The clock advantage also explains the FP32 gap: 10.65 TFLOPS versus 4.096 TFLOPS is a 2.6x difference, despite identical shading unit counts of 1024.

Memory bandwidth creates another decisive split. The RX 9050's 288.0 GB/s exceeds the A380E's 186.0 GB/s by 55%. With 8 GB versus 6 GB capacity, the RX 9050 also handles larger working sets before hitting memory limits. The A380E's narrower 96-bit bus and slower 1937 MHz memory clock both contribute to its bandwidth deficit.

Ray tracing performance follows the core count ratio. The RX 9050's 16 RT cores double the A380E's 8, suggesting roughly twice the ray intersection throughput, though no direct benchmark confirms this. The RX 9050's active production status and newer architecture (RDNA 4.0 versus Xe-HPG) imply better driver optimization going forward, but the database records no empirical scores to quantify this.

In FP16 workloads, the A380E narrows the gap due to its 2:1 ratio, reaching 8.192 TFLOPS against the RX 9050's 10.65 TFLOPS. The RX 9050 still leads by 30%, but the A380E's FP16 advantage over its own FP32 number suggests some compute workloads may see relatively better performance on the Intel part.

The RX 9050 leads in every performance-related specification. The A380E counters with lower power draw, smaller physical footprint, no power connector requirement, and more display outputs. Both GPUs share identical shading unit counts, TMU counts, DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4. The RX 9050's newer node, higher transistor count, and larger die all point toward its substantial compute advantage. The A380E's flat 2000 MHz clock across base and boost suggests a conservative design aimed at consistent operation rather than peak performance.
