AMD Radeon RX 7900M vs Intel Arc A380E Comparison

Where Each One Wins

The recorded data presents an unusual matchup. The AMD Radeon RX 7900M sits at the 94th percentile among all GPUs in the database, while the Intel Arc A380E sits at the 50th percentile. That percentile gap alone indicates these are not competing in the same performance class. The RX 7900M carries three benchmark entries: a 3DMark Steel Nomad DX12 score of 4201, a Geekbench OpenCL score of 129499, and a Geekbench Vulkan score of 158760. The Arc A380E has zero recorded benchmark entries, so no direct head-to-head test scores exist in the database for these two products.

The use-case split is therefore defined by the data that is present. The RX 7900M wins every measurable category by default because the A380E has no benchmark records. However, the absence of data for the A380E does not mean it has no purpose; its specification profile suggests a different deployment target. With a 75 W TDP, a 6 GB memory pool, and a 96-bit memory bus, the A380E is configured for low-power, compact, embedded or edge workloads. The RX 7900M, with a 180 W TDP, 16 GB of memory, and a 256-bit bus, targets high-end mobile rendering, compute, or content creation tasks.

The RX 7900M's average benchmark score of 97487 places it among workstation-class accelerators. Its nearest rivals in the database include the AMD Radeon Pro VII at 97131 (0.4% ahead of the RX 7900M), the NVIDIA Quadro RTX 6000 at 101872 (the RX 7900M trails by 4.3%), the AMD Radeon Instinct MI60 at 92466 (the RX 7900M leads by 5.4%), and the NVIDIA RTX A4500 at 91671 (the RX 7900M leads by 6.3%). These deltas are modest, indicating the RX 7900M clusters tightly with high-end professional GPUs. The Arc A380E has no rival list, meaning the database does not place it in any comparable performance bracket.

Architecture Differences

The two GPUs diverge sharply in architecture, process node, and die complexity. The AMD Radeon RX 7900M uses the Navi 31 chip with RDNA 3.0 architecture, codename Plum Bonito, manufactured on a 5 nm process at TSMC. The Intel Arc A380E uses the DG2-128 chip with Xe-HPG architecture, generation Alchemist (Arc 3), also manufactured at TSMC but on a 6 nm process. The node difference is significant: 5 nm versus 6 nm.

Transistor counts reveal the scale gap. The RX 7900M integrates 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The Arc A380E integrates 7,200 million transistors on a 157 mm² die, with a density of 45.9 million per mm². The RX 7900M has roughly eight times the transistor count and over three times the die area. The density ratio (109.1 versus 45.9 million per mm²) shows the AMD part packs transistors much more tightly, consistent with the more advanced process node.

Memory architecture differs substantially. The RX 7900M has 16 GB of GDDR6 on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The Arc A380E has 6 GB of GDDR6 on a 96-bit bus, delivering 186.0 GB/s. The RX 7900M provides 3.1 times the bandwidth. Clock behavior also differs: the RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz, while the Arc A380E runs a flat 2000 MHz for both base and boost. Memory clocks differ as well: the RX 7900M runs at 2250 MHz (18 Gbps effective), the A380E at 1937 MHz (15.5 Gbps effective).

Compute resources are far apart. The RX 7900M has 4608 shading units, 288 TMUs, 192 ROPs, and 72 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The RX 7900M leads by 4.5 times in shading units, 4.5 times in TMUs, 6 times in ROPs, and 9 times in ray tracing cores. Pixel rate is 401.3 GPixel/s versus 64.00 GPixel/s. Texture rate is 601.9 GTexel/s versus 128.0 GTexel/s. FP32 throughput is 38.52 TFLOPS versus 4.096 TFLOPS, a 9.4 times gap. FP16 throughput is 77.05 TFLOPS versus 8.192 TFLOPS, also a 9.4 times gap.

Physical and integration differences matter. The RX 7900M is classified as IGP (integrated graphics processor) with no power connectors and portable device dependent display outputs, indicating it is designed for mobile integration. The Arc A380E is a single-slot card with dimensions of 254 mm length, 127 mm height, and 20 mm width, with 4x DisplayPort 2.0 outputs. It requires a 250 W suggested PSU. The RX 7900M connects via PCIe 4.0 x16, the A380E via PCIe 4.0 x8.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for the RX 7900M versus the Arc A380E. The headToHeadBenchmarks field is empty, and the wins counters are zero for both sides. The RX 7900M does have standalone benchmark results that can be interpreted against the broader database. Its 3DMark Steel Nomad DX12 score of 4201, Geekbench OpenCL score of 129499, and Geekbench Vulkan score of 158760 establish a performance envelope.

The Arc A380E has no recorded scores, so its measured performance cannot be quantified from the database. The only comparative signals are the percentile ranks: 94 for the RX 7900M versus 50 for the A380E. A 44 percentile-point gap indicates a very large performance separation in the database's global distribution.

For the RX 7900M, the nearest rival comparisons provide context. The AMD Radeon Pro VII scores 97131 on average, just 0.4% below the RX 7900M's 97487. The NVIDIA Quadro RTX 6000 scores 101872, putting the RX 7900M 4.3% behind. The AMD Radeon Instinct MI60 scores 92466, putting the RX 7900M 5.4% ahead. The NVIDIA RTX A4500 scores 91671, putting the RX 7900M 6.3% ahead. These numbers show the RX 7900M sits in a competitive band with professional workstation GPUs from both AMD and NVIDIA, within a single-digit percentage range.

The A380E has no rival data, so no such comparisons are possible. The database records its average benchmark score as zero, which is consistent with the empty benchmarks array. This does not indicate a broken product; it indicates a lack of measured results in the database.

The Verdict

The data supports a clear separation of roles. The AMD Radeon RX 7900M is a high-performance mobile GPU with a 94th percentile rank, an average benchmark score of 97487, and nearest rivals that include the NVIDIA Quadro RTX 6000 and the AMD Radeon Pro VII. Its 38.52 TFLOPS FP32 throughput, 576.0 GB/s bandwidth, and 16 GB memory pool position it for demanding workloads such as high-resolution rendering, large dataset compute, or advanced ray tracing. The 180 W TDP and IGP classification indicate it is intended for integration into premium portable systems where performance density matters.

The Intel Arc A380E is a different class of device. Its 50th percentile rank, 75 W TDP, single-slot form factor, and 4x DisplayPort 2.0 outputs suggest a low-power discrete card for multi-display setups, embedded systems, or compact workstations. The 4.096 TFLOPS FP32 throughput and 186.0 GB/s bandwidth are sufficient for modest graphics tasks but far below the RX 7900M's capabilities. Its end-of-life production status and listed successor, Battlemage, indicate it is a transitional product in Intel's Arc lineup.

For users requiring maximum compute and graphics throughput in a mobile or portable form, the RX 7900M is the only choice supported by measured data. For users needing a low-profile, low-power card with four DisplayPort outputs and no external power connectors, the Arc A380E has a specification profile that fits that niche, but the database contains no benchmark scores to validate its performance. The RX 7900M leads in every recorded metric: compute throughput, memory bandwidth, pixel rate, texture rate, shading units, and ray tracing cores. The absence of A380E benchmark data means its real-world performance remains unquantified in this database.
