AMD Radeon 880M vs Intel Arc A380E Comparison

Where Each One Wins

The AMD Radeon 880M and Intel Arc A380E occupy different positions in the performance spectrum, and the recorded data shows a clear split in their respective strengths. The Radeon 880M is an integrated graphics processor built into the Strix Point mobile chip, designed to operate within a 15 W power envelope. The Arc A380E is a discrete, single-slot card with a 75 W TDP, 6 GB of dedicated GDDR6 memory, and a 186.0 GB/s memory bandwidth. These fundamental differences dictate where each part wins.

The Radeon 880M wins in raw compute throughput in certain workloads. Its FP32 output is 4.454 TFLOPS, which is 8.7% higher than the Arc A380E's 4.096 TFLOPS. In pixel filling, however, the Arc A380E takes the lead with a 64.00 GPixel/s pixel rate versus 46.40 GPixel/s for the 880M, a 37.9% advantage. Texture rate favors the AMD part: 139.2 GTexel/s against 128.0 GTexel/s, a 8.75% margin. The Arc A380E doubles the Radeon 880M in FP16 throughput, delivering 8.192 TFLOPS versus 4.454 TFLOPS, though the AMD part runs FP16 at a 1:1 ratio with FP32 while Intel uses a 2:1 ratio.

In terms of memory, the Arc A380E has a decisive advantage. It has 6 GB of dedicated GDDR6 on a 96-bit bus, yielding 186.0 GB/s of bandwidth. The Radeon 880M relies on system shared memory with bandwidth described as system dependent. This means the discrete Intel card does not compete with the CPU for memory access, while the integrated AMD part does. For workloads that saturate memory bandwidth, the Arc A380E is the clear winner.

The Radeon 880M wins in transistor efficiency and density. Its 34,000 million transistors are packed into a 233 mm² die on a 4 nm TSMC process, producing a density of 145.9M transistors per mm². The Arc A380E uses 7,200 million transistors on a 157 mm² die at 6 nm, yielding 45.9M per mm². The AMD part achieves more than three times the transistor density of the Intel part.

Architecture Differences

The two GPUs come from different architectural families and process nodes. The Radeon 880M is built on RDNA 3.5 and is part of the Navi III IGP generation, specifically the Strix Point mobile chip. It is manufactured by TSMC on a 4 nm process. The Intel Arc A380E is built on Xe-HPG, part of the Alchemist (Arc 3) generation, using the DG2-128 chip. It is also manufactured by TSMC but on a 6 nm process.

The compute configurations differ significantly. The Radeon 880M has 768 shading units, 48 texture mapping units, 16 ROPs, and 12 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Despite having fewer shading units, the AMD part achieves higher FP32 throughput because of its higher boost clock of 2900 MHz versus 2000 MHz for the Intel card. The base clock of the Arc A380E is also 2000 MHz, meaning it runs at a fixed clock, while the Radeon 880M has a 400 MHz base and boosts to 2900 MHz.

Memory architecture is a major differentiator. The Radeon 880M uses system shared memory with no dedicated VRAM, while the Arc A380E has 6 GB of GDDR6 running at 1937 MHz (15.5 Gbps effective) on a 96-bit bus. The Intel card's bandwidth is 186.0 GB/s; the AMD part's bandwidth is system dependent, so no fixed figure exists in the database for it.

Power and physical design also separate them. The Radeon 880M is an IGP with a 15 W TDP, no power connectors, and no slot width since it is integrated into the processor. The Arc A380E is a single-slot card measuring 254 mm in length, 127 mm in height, and 20 mm in width, with a 75 W TDP and no power connectors. The database lists a suggested PSU of 250 W for the Intel card. The Arc A380E provides four DisplayPort 2.0 outputs, while the Radeon 880M's display outputs are portable device dependent.

API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status differs: the Radeon 880M is active, while the Arc A380E is end-of-life with a successor named Battlemage. The Radeon 880M's predecessor is Navi II IGP, while the Arc A380E's predecessor is Xe Graphics.

Head-to-Head Benchmarks

The database contains a full benchmark suite for the AMD Radeon 880M, but no recorded benchmark scores for the Intel Arc A380E. The head-to-head benchmark array is empty, and the wins counters for both parts are zero. As a result, direct numerical comparisons must rely on the Radeon 880M's recorded scores and the architectural specifications of both parts.

The Radeon 880M's average benchmark score is 8436, placing it at the 43rd percentile of all GPUs in the database. Its nearest rivals include the NVIDIA GeForce GTX 675MX with an average score of 8427, which is 0.1% behind the AMD part; the NVIDIA GeForce MX330 at 8458, which is 0.3% ahead; the AMD Radeon HD 8870M at 8462, also 0.3% ahead; and the AMD Radeon R9 M375X at 8325, which is 1.3% behind. These margins are small, indicating that the Radeon 880M sits in a tightly contested performance band.

In individual tests, the Radeon 880M scores 535 in 3DMark Steel Nomad DX12, 31285 in Geekbench OpenCL, and 40006 in Geekbench Vulkan. Its Passmark results are 31 in DirectX 10, 73 in DirectX 11, 32 in DirectX 12, 97 in DirectX 9, 969 in G2D, 7615 in G3D, and 3719 in GPU compute.

Since the Arc A380E has no benchmark scores in the database, its position must be inferred from its specification sheet. The Intel part has a higher pixel rate (64.00 GPixel/s versus 46.40 GPixel/s) and higher FP16 throughput (8.192 TFLOPS versus 4.454 TFLOPS), but lower FP32 (4.096 TFLOPS versus 4.454 TFLOPS) and lower texture rate (128.0 GTexel/s versus 139.2 GTexel/s). The Arc A380E also holds a 50th percentile ranking among all GPUs, which is 7 percentage points above the Radeon 880M's 43rd percentile, though that percentile is computed without any recorded benchmark scores for the Intel part.

The Radeon 880M's FP32 advantage of 8.7% over the Arc A380E is meaningful for general compute workloads. The Arc A380E's FP16 advantage of 83.9% is substantial for workloads that can use packed math. The pixel rate gap of 37.9% in favor of Intel suggests the Arc A380E is better suited to fill-rate-bound scenarios, such as heavy pixel shading at high resolutions. The texture rate gap of 8.75% in favor of AMD indicates the Radeon 880M handles texture-heavy workloads slightly better.

The Verdict

The data shows that the AMD Radeon 880M and Intel Arc A380E serve different roles, and the choice between them depends on the workload priority. The Radeon 880M is an integrated part with a 15 W TDP that achieves 4.454 TFLOPS of FP32, a 139.2 GTexel/s texture rate, and a 43rd percentile ranking with an average benchmark score of 8436. It is built on a 4 nm process with 34,000 million transistors and offers 12 ray tracing cores. Its nearest rivals are all within 1.3% of its average score, placing it in a narrow competitive band that includes the GeForce GTX 675MX, MX330, Radeon HD 8870M, and Radeon R9 M375X.

The Intel Arc A380E is a discrete single-slot card with a 75 W TDP, 6 GB of GDDR6, and 186.0 GB/s of bandwidth. It leads in pixel rate at 64.00 GPixel/s, FP16 at 8.192 TFLOPS, and shading unit count at 1024. It is ranked at the 50th percentile of all GPUs, though this ranking is based on no recorded benchmark scores. Its FP32 output is lower than the AMD part, and its texture rate is also lower.

For users who need a low-power integrated solution with strong FP32 compute and texture throughput, the Radeon 880M is the appropriate choice. For scenarios that require dedicated memory, high pixel fill rate, or FP16 throughput, the Arc A380E is the better fit based on the specification data. The absence of benchmark scores for the Intel part means its real-world performance cannot be verified from the database, while the Radeon 880M has a complete set of recorded results across 3DMark, Geekbench, and Passmark tests. The verdict from the data is straightforward: the Radeon 880M is the measured performer, and the Arc A380E is the specification-driven alternative with clear advantages in memory and fill rate.
