Where Each One Wins

The recorded data splits clearly along compute and memory lines. The AMD Radeon RX 7700 dominates every measured benchmark category in the database. Its PassMark G3D score is 20974, and its average benchmark score across all tests is 15852. The Intel Arc A380E x2 has no recorded benchmark scores in the database, with an average benchmark score of 0. This means the RX 7700 holds wins in all recorded categories, including 3DMark Steel Nomad DX12 with a score of 2865, Geekbench OpenCL with 106028, and PassMark GPU Compute with 10963.

The Arc A380E x2 does hold advantages in specific non-performance areas. It is a single-slot card with a width of 20 mm, compared to the RX 7700's dual-slot width of 50 mm. The Intel card requires a single 6-pin power connector and a 300 W suggested PSU, while the AMD card needs two 8-pin connectors and a 550 W suggested PSU. The Arc A380E x2 also offers eight mini-DisplayPort 2.0 outputs, whereas the RX 7700 provides one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C output. For multi-display or dense deployment scenarios, the Arc A380E x2 presents a clear physical and connectivity advantage.

In terms of transistor density, the RX 7700 packs 81.2 million transistors per square millimeter on a 346 mm² die with 28,100 million total transistors. The Arc A380E x2 has a density of 45.9 million transistors per square millimeter on a 157 mm² die with 7,200 million total transistors. The RX 7700 also leads in pixel rate at 236.1 GPixel/s versus 64.00 GPixel/s, and in texture rate at 393.4 GTexel/s versus 128.0 GTexel/s.

Architecture Differences

The RX 7700 is built on RDNA 3.0 with the Navi 32 chip, part of the Navi III generation under the codename Wheat Nas. The Arc A380E x2 is built on Intel's Xe-HPG architecture with the DG2-128 chip, part of the Alchemist generation under the Arc 3 series. The process nodes differ: TSMC 5 nm for AMD versus TSMC 6 nm for Intel. The RX 7700 has a larger die at 346 mm² versus 157 mm², and a substantially higher transistor count at 28,100 million versus 7,200 million.

The ray tracing hardware scales accordingly. The RX 7700 has 40 RT cores, while the Arc A380E x2 has 8 RT cores. Neither card has tensor cores in the database. The FP16 compute ratio differs: the RX 7700 achieves 25.18 TFLOPS at a 1:1 ratio with FP32, while the Arc A380E x2 achieves 8.192 TFLOPS at a 2:1 ratio, meaning its FP16 throughput is double its FP32 rate.

The memory architecture is a major divider. The RX 7700 uses a 256-bit bus with 16 GB of GDDR6, while the Arc A380E x2 uses a 96-bit bus with 6 GB of GDDR6. The bandwidth gap is wide: 624.1 GB/s versus 186.0 GB/s. The memory clocks also differ, with the RX 7700 running at 2438 MHz (19.5 Gbps effective) and the Arc A380E x2 at 1937 MHz (15.5 Gbps effective).

The bus interfaces differ as well. The RX 7700 uses PCIe 4.0 x16, and the Arc A380E x2 uses PCIe 4.0 x8, which halves the available host interface lanes for the Intel part.

Specification Differences

The two cards differ across nearly every physical and electrical specification. The RX 7700 has a base clock of 1900 MHz and a boost clock of 2459 MHz, with a game clock of 2041 MHz. The Arc A380E x2 has a base clock of 2000 MHz and a boost clock of 2000 MHz, with no game clock listed. The RX 7700 has a higher boost clock by 459 MHz.

Power requirements diverge sharply. The RX 7700 has a TDP of 200 W, requires two 8-pin power connectors, and a 550 W suggested PSU. The Arc A380E x2 has a TDP of 130 W, requires one 6-pin power connector, and a 300 W suggested PSU. The slot width also differs: dual-slot for AMD versus single-slot for Intel.

Physical dimensions show the RX 7700 is longer and taller: 267 mm length, 135 mm height, and 50 mm width. The Arc A380E x2 measures 265 mm length, 127 mm height, and 20 mm width. The Intel card is thinner by 30 mm and shorter by 2 mm.

Display outputs are completely different. The RX 7700 offers one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C. The Arc A380E x2 offers eight mini-DisplayPort 2.0 outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The production status differs: the RX 7700 is Active, and the Arc A380E x2 is End-of-life. The predecessor and successor names differ: the RX 7700 follows Navi II and precedes Navi IV, while the Arc A380E x2 follows Xe Graphics and precedes Battlemage.

Head-to-Head Benchmarks

The head-to-head benchmark comparison in the database contains no paired test entries, so the direct comparison relies on the individually recorded scores. The RX 7700 has a full set of benchmark results, while the Arc A380E x2 has no recorded benchmark scores at all, making its average benchmark score 0.

The RX 7700's performance profile is substantial across the board. In 3DMark Steel Nomad DX12, it scores 2865. In Geekbench OpenCL, it scores 106028. The PassMark suite shows a G3D score of 20974 and a GPU Compute score of 10963. Its DirectX legacy scores are 261 for DX9, 186 for DX11, 96 for DX12, and 92 for DX10. The 2D score is 1206.

The RX 7700's percentile rank among all GPUs is 58, and its nearest rivals provide context. The AMD Radeon R9 370X has an average score of 15862, which is 0.1% higher than the RX 7700's 15852. The AMD Radeon RX 9060 scores 16014, a 1% advantage. The AMD Radeon Pro W5500 scores 15679, which is 1.1% lower. The NVIDIA GeForce RTX 3060 Ti scores 16129, a 1.7% advantage. These delta percentages indicate the RX 7700 sits within a tight performance cluster around the 15.7k to 16.1k average score range.

Since the Arc A380E x2 has no recorded benchmark scores and no nearest rivals listed, its percentile rank of 50 cannot be directly compared with the RX 7700's 58 through any measured delta. The data shows the RX 7700 is the only card in this pairing with measurable performance results, and its scores place it in the upper-mid range of the database's GPU population. The Arc A380E x2's lack of recorded data precludes any quantitative comparison of compute, graphics, or memory throughput between the two cards.
