AMD Radeon RX 7900 GRE vs Intel Arc A380E Comparison

# AMD Radeon RX 7900 GRE vs Intel Arc A380E

The AMD Radeon RX 7900 GRE and Intel Arc A380E occupy entirely different segments of the GPU market, and the recorded data confirms a massive performance gulf between them. The RX 7900 GRE sits in the 77th percentile of all GPUs in the database, while the Arc A380E sits in the 50th percentile. The RX 7900 GRE carries an average benchmark score of 32,456 across its recorded tests, whereas the Arc A380E has no recorded benchmark scores in the database, leaving its average at zero. This comparison therefore relies on the RX 7900 GRE's measured results and the architectural specifications of both parts.

Where Each One Wins

The RX 7900 GRE wins every measurable performance category in this comparison. It is a high-end desktop part from the Radeon RX 7000 series, built for demanding workloads such as 4K gaming, heavy compute, and ray-traced rendering. Its recorded benchmarks show strong results across DirectX 12, OpenCL, Vulkan, and legacy DirectX tests. The Arc A380E, by contrast, is an embedded-oriented card from Intel's Alchemist generation, designed for low-power systems where slot width, power draw, and thermal footprint matter more than raw throughput.

The RX 7900 GRE posts a Passmark G3D score of 27,089, a Geekbench OpenCL score of 175,758, and a Geekbench Vulkan score of 99,850. These numbers indicate a card that can handle high-resolution gaming and GPU compute workloads with substantial headroom. The Arc A380E has no benchmark scores in the database, so its wins are limited to physical and power characteristics: it is a single-slot card with no external power connectors, a 75 W TDP, and a 250 W suggested PSU. The RX 7900 GRE requires a 260 W TDP, dual-slot cooling, two 8-pin power connectors, and a 600 W suggested PSU.

The use-case split is clear. The RX 7900 GRE is for performance-oriented desktop builds that prioritize frame rates, compute throughput, and feature support. The Arc A380E is for compact, low-power, or embedded systems where the card's 75 W draw, single-slot profile, and lack of power connectors simplify integration. The Arc A380E also provides four DisplayPort 2.0 outputs, which can serve multi-display setups, while the RX 7900 GRE offers one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C output.

Architecture Differences

The two cards are built on different architectures, process nodes, and chip layouts. The RX 7900 GRE uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito, from the Navi III generation. It is fabricated on a 5 nm process at TSMC and contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The Arc A380E uses the DG2-128 chip with Xe-HPG architecture from the Alchemist generation. It is manufactured on a 6 nm process at TSMC and contains 7,200 million transistors on a 157 mm² die, with a density of 45.9 million per mm².

The compute resources differ by an order of magnitude. The RX 7900 GRE has 5,120 shading units, 320 texture mapping units, 160 ROPs, and 80 ray tracing cores. The Arc A380E has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Neither card includes tensor cores in the database records. The RX 7900 GRE's pixel rate is 359.2 GPixel/s and its texture rate is 718.4 GTexel/s. The Arc A380E's pixel rate is 64.00 GPixel/s and its texture rate is 128.0 GTexel/s. FP32 throughput is 45.98 TFLOPS for the RX 7900 GRE versus 4.096 TFLOPS for the Arc A380E. FP16 performance follows the same 2:1 ratio on both cards: 91.96 TFLOPS for the RX 7900 GRE and 8.192 TFLOPS for the Arc A380E.

Clock behavior also differs. The RX 7900 GRE has a base clock of 1287 MHz, a game clock of 1880 MHz, and a boost clock of 2245 MHz. The Arc A380E has a fixed base and boost clock of 2000 MHz, with no game clock listed. Memory clocks differ as well: the RX 7900 GRE runs at 2250 MHz with 18 Gbps effective, while the Arc A380E runs at 1937 MHz with 15.5 Gbps effective.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two cards, and the Arc A380E has no individual benchmark scores recorded. The comparison therefore rests on the RX 7900 GRE's measured results versus the Arc A380E's absence of recorded data. The RX 7900 GRE's 3DMark Steel Nomad DX12 score is 4,814. Its Geekbench OpenCL score is 175,758, and its Geekbench Vulkan score is 99,850. These results place it well within the top quarter of all GPUs, at the 77th percentile.

Passmark results for the RX 7900 GRE show a G3D score of 27,089, a GPU compute score of 15,016, a G2D score of 1,180, a DirectX 11 score of 300, a DirectX 9 score of 310, a DirectX 10 score of 139, and a DirectX 12 score of 107. These numbers span both modern and legacy APIs, indicating broad driver coverage across DirectX versions. The Arc A380E has no comparable figures, so no direct percentage deltas can be computed. The nearest rivals for the RX 7900 GRE in the database are the AMD FirePro S10000 at 32,388 average score (0.2% behind), the AMD FirePro S9300 X2 at 32,540 (0.3% ahead), the AMD Radeon RX 590 GME at 32,601 (0.4% ahead), and the AMD Radeon Pro 570X at 32,176 (0.9% behind). These deltas are tiny, showing that the RX 7900 GRE's average score of 32,456 sits in a tightly clustered band among those four cards.

Specification Differences

The memory subsystems are fundamentally different. The RX 7900 GRE has 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s of bandwidth. The Arc A380E has 6 GB of GDDR6 on a 96-bit bus with 186.0 GB/s of bandwidth. The RX 7900 GRE more than triples the memory bandwidth and carries nearly three times the capacity.

Power and physical design diverge sharply. The RX 7900 GRE has a 260 W TDP, requires two 8-pin power connectors, and recommends a 600 W PSU. The Arc A380E has a 75 W TDP, requires no external power connectors, and recommends a 250 W PSU. The RX 7900 GRE is dual-slot with dimensions of 276 mm length, 110 mm height, and 51 mm width. The Arc A380E is single-slot with dimensions of 254 mm length, 127 mm height, and 20 mm width. The RX 7900 GRE is longer and thicker, while the Arc A380E is taller and dramatically thinner.

Bus interfaces differ as well. The RX 7900 GRE uses PCIe 4.0 x16, while the Arc A380E uses PCIe 4.0 x8. Display outputs are also distinct: the RX 7900 GRE provides one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C; the Arc A380E provides four DisplayPort 2.0 outputs. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Production status separates the two. The RX 7900 GRE is listed as Active, released on 2023-07-26, with a launch MSRP of 549 USD. The Arc A380E is listed as End-of-life, released on 2024-03-31, with no launch MSRP recorded. The RX 7900 GRE's predecessor is Navi II and its successor is Navi IV. The Arc A380E's predecessor is Xe Graphics and its successor is Battlemage.
