AMD Radeon RX 6600 LE vs Intel Arc A380E Comparison

The AMD Radeon RX 6600 LE and the Intel Arc A380E occupy different tiers of the graphics card market, as evidenced by the recorded data. The RX 6600 LE delivers far higher raw compute throughput and memory bandwidth, while the Arc A380E counters with a smaller physical footprint, lower power draw, and a broader set of display outputs. The database shows the RX 6600 LE sitting at the 91st percentile among all GPUs, with an average benchmark score of 70,829, while the Arc A380E holds only the 50th percentile and has no recorded synthetic benchmark scores. The following sections break down the architectural, specification, and performance differences between these two very different cards.

Where Each One Wins

The AMD Radeon RX 6600 LE is the clear winner in raw compute and rendering performance. Its OpenCL score of 69,229 and Vulkan score of 72,428 place it in the upper tier of the database, and its average score of 70,829 puts it slightly ahead of the NVIDIA Quadro P6000 (69,986, a 1.2% difference) and the AMD Radeon Pro WX 8200 (69,870, a 1.4% difference). It trails the AMD Radeon RX 6650M (71,768) by 1.3% and the NVIDIA RTX A3000 Mobile (70,140) by 1%. These margins show that the RX 6600 LE is a solid performer for its class, competitive with professional mobile and workstation cards in synthetic workloads. The card uses 1,792 shading units, 112 texture mapping units, and 64 render output units, and it achieves 8.942 TFLOPS of FP32 compute. Its 224.0 GB/s of memory bandwidth, delivered over a 128-bit bus with 8 GB of GDDR6, gives it a substantial advantage in bandwidth-heavy tasks.

The Intel Arc A380E, by contrast, wins in the areas of physical design and power efficiency. It is a single-slot card measuring 254 mm by 127 mm by 20 mm, while the RX 6600 LE is a dual-slot card at 190 mm by 110 mm by 40 mm. The Arc A380E draws only 75 W of power and requires no external power connectors, whereas the RX 6600 LE has a 132 W TDP and requires a single 8-pin connector. The Intel card also offers four DisplayPort 2.0 outputs, while the AMD card provides one HDMI 2.1 and three DisplayPort 1.4a outputs. For systems where space, power, or multi-display connectivity is the priority, the Arc A380E has the advantage. Its 6 GB of GDDR6 memory on a 96-bit bus yields 186.0 GB/s of bandwidth, which is lower than the AMD card but still sufficient for lighter workloads.

Architecture Differences

The two cards come from different architectural lineages. The AMD Radeon RX 6600 LE uses the Navi 23 chip built on RDNA 2.0, a 7 nm design produced at TSMC. It integrates 11,060 million transistors on a 237 mm² die, resulting in a transistor density of 46.7 million per square millimeter. The Intel Arc A380E uses the DG2-128 chip based on Xe-HPG architecture, built on a 6 nm process, also at TSMC. It contains 7,200 million transistors on a 157 mm² die, for a density of 45.9 million per square millimeter. The newer process node gives Intel a smaller die and lower transistor count, but the architectural designs differ in how those resources are deployed.

The RX 6600 LE carries 28 ray tracing cores, 1,792 shading units, 112 TMUs, and 64 ROPs. Its FP16 throughput is 17.88 TFLOPS, exactly double its FP32 rate, indicating a 2:1 ratio. The Arc A380E has 8 ray tracing cores, 1,024 shading units, 64 TMUs, and 32 ROPs. Its FP16 throughput is 8.192 TFLOPS, also a 2:1 ratio over its 4.096 TFLOPS FP32 figure. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so feature-level API support is identical even though the underlying architectures are completely different. The production status also differs: the RX 6600 LE is listed as active, while the Arc A380E is end-of-life. The AMD card was released on December 7, 2023, and the Intel card on March 31, 2024.

Specification Differences

The two cards differ in nearly every major specification category. The process node is 7 nm for AMD and 6 nm for Intel. Transistor counts are 11,060 million versus 7,200 million, and die sizes are 237 mm² versus 157 mm². Clock speeds differ substantially: the RX 6600 LE runs at a base of 1626 MHz and boosts to 2495 MHz, while the Arc A380E runs at a fixed 2000 MHz for both base and boost. Memory clocks are 1750 MHz (14 Gbps effective) for AMD and 1937 MHz (15.5 Gbps effective) for Intel, though the AMD card wins on total bandwidth due to its wider bus.

The RX 6600 LE has 1792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. The Arc A380E has 1024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. Pixel rate is 159.7 GPixel/s for AMD versus 64.00 GPixel/s for Intel, and texture rate is 279.4 GTexel/s versus 128.0 GTexel/s. FP32 performance is 8.942 TFLOPS versus 4.096 TFLOPS, and FP16 is 17.88 TFLOPS versus 8.192 TFLOPS. The AMD card is dual-slot with a 1x 8-pin connector and a 300 W suggested PSU, while the Intel card is single-slot with no power connectors and a 250 W suggested PSU. Physical dimensions are 190 mm by 110 mm by 40 mm for AMD and 254 mm by 127 mm by 20 mm for Intel. The RX 6600 LE is in active production, while the Arc A380E is end-of-life.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two cards, and the Intel Arc A380E has no individual benchmark scores recorded. However, the available data for the RX 6600 LE allows a comparison through its nearest rivals. The AMD card's OpenCL score of 69,229 and Vulkan score of 72,428 are the only direct performance measurements in the database. Its average of 70,829 places it just above the NVIDIA Quadro P6000 (69,986, 1.2% faster) and the AMD Radeon Pro WX 8200 (69,870, 1.4% faster), while sitting slightly below the NVIDIA RTX A3000 Mobile (70,140, 1% slower) and the AMD Radeon RX 6650M (71,768, 1.3% slower).

The Arc A380E lacks any recorded scores, so its performance cannot be positioned numerically against the RX 6600 LE or any other GPU. The percentile gap is stark: 91st for the RX 6600 LE versus 50th for the Arc A380E. In terms of raw throughput, the RX 6600 LE delivers 8.942 TFLOPS of FP32 compute, more than double the Arc A380E's 4.096 TFLOPS. The AMD card also has more than double the pixel rate (159.7 GPixel/s versus 64.00 GPixel/s) and texture rate (279.4 GTexel/s versus 128.0 GTexel/s). Memory bandwidth favors AMD by 224.0 GB/s to 186.0 GB/s, and the AMD card carries 8 GB of VRAM versus 6 GB. The Intel card holds advantages only in clock speed (2000 MHz fixed versus 1626 MHz base and 2495 MHz boost), memory clock (1937 MHz versus 1750 MHz), power draw (75 W versus 132 W), and physical footprint. The recorded data shows a clear performance hierarchy, with the RX 6600 LE occupying a far higher tier despite the Arc A380E's efficiency and connectivity strengths.
