AMD Radeon RX 6600 LE vs Intel Arc A550M Comparison

FAQ

Q: Which GPU has the higher average benchmark score?

A: The AMD Radeon RX 6600 LE records an average benchmark score of 70829, placing it in the 91st percentile of all GPUs. The Intel Arc A550M averages 49737, which sits in the 86th percentile.

Q: How large is the performance gap in the OpenCL test?

A: The AMD Radeon RX 6600 LE scores 69229 in Geekbench OpenCL, which is 38.8% ahead of the Intel Arc A550M's 49894. This is the smaller of the two deltas between these parts.

Q: What about the Vulkan benchmark results?

A: In Geekbench Vulkan, the AMD Radeon RX 6600 LE scores 72428 versus 49580 for the Intel Arc A550M. The delta here is 46.1%, making Vulkan the larger win for AMD.

Q: Are these cards similar in memory configuration?

A: Yes, both GPUs use 8 GB of GDDR6 memory on a 128-bit bus, and both deliver 224.0 GB/s of bandwidth. The memory clock is identical at 1750 MHz, with 14 Gbps effective data rate.

Q: Which GPU has the higher transistor count?

A: The Intel Arc A550M packs 21,700 million transistors on its DG2-512 chip, while the AMD Radeon RX 6600 LE has 11,060 million transistors on Navi 23. Intel's die is also larger at 406 mm² versus 237 mm².

Q: What is the thermal design power difference?

A: The AMD Radeon RX 6600 LE has a TDP of 132 W and requires a 300 W suggested power supply with a 1x 8-pin connector. The Intel Arc A550M has a much lower TDP of 60 W and is classified as an IGP, meaning it uses no discrete power connectors.

Architecture Differences

The AMD Radeon RX 6600 LE is built on the RDNA 2.0 architecture using the Navi 23 chip, fabricated on a 7 nm process at TSMC. The Intel Arc A550M uses the Xe-HPG architecture with the DG2-512 chip, produced on a 6 nm node, also at TSMC. This process difference is notable: Intel's newer node allows for a substantially larger die, measuring 406 mm² versus AMD's 237 mm², while transistor density is higher on Intel's part at 53.4M per mm² compared to 46.7M per mm².

The Intel chip contains 21,700 million transistors, almost double AMD's 11,060 million. This large transistor budget funds a wider compute configuration: the Arc A550M has 2048 shading units, 128 texture mapping units, and 64 ROPs. The AMD card has 1792 shading units, 112 TMUs, and the same 64 ROPs. In ray tracing, AMD holds the count advantage with 28 dedicated RT cores versus Intel's 16, though the architectural implementations differ fundamentally between RDNA 2.0 and Xe-HPG.

Clock behavior separates the two parts significantly. AMD runs a base clock of 1626 MHz and a boost of 2495 MHz, with a game clock rated at 2045 MHz. Intel's base clock is much lower at 900 MHz, and its boost reaches 2050 MHz. Despite Intel's larger compute array, the lower clocks cap its peak throughput. The pixel rate tells this story: AMD achieves 159.7 GPixel/s against Intel's 131.2 GPixel/s. Texture rate also favors AMD at 279.4 GTexel/s versus 262.4 GTexel/s.

Power delivery differs sharply. The AMD card is a dual-slot design, 190 mm long, with a 1x 8-pin power connector and a 300 W suggested PSU. The Intel part is classified as an IGP, meaning it is designed to be integrated into a portable device, consumes 60 W, and has no discrete power connector. The bus interface also differs: AMD uses PCIe 4.0 x8, while Intel uses PCIe 4.0 x16. Display outputs are distinct as well, with AMD providing 1x HDMI 2.1 and 3x DisplayPort 1.4a, while Intel's outputs are described as portable device dependent.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status diverges: AMD's part is active, while Intel's is end-of-life.

The Verdict

The benchmark data points decisively toward the AMD Radeon RX 6600 LE for raw compute performance. Its average score of 70829 places it 1% ahead of the NVIDIA RTX A3000 Mobile, 1.2% ahead of the NVIDIA Quadro P6000, and 1.4% ahead of the AMD Radeon Pro WX 8200. The only nearby rival it trails is the AMD Radeon RX 6650M, which leads by 1.3%. The Intel Arc A550M, by contrast, averages 49737, which puts it 0.4% behind the NVIDIA GeForce RTX 5070 Ti, 0.5% behind the AMD Radeon RX Vega 64, and 2.4% behind the AMD Radeon RX 6900 XT. It manages to lead the AMD Radeon RX 6800 XT by 2.6%.

For desktop users seeking maximum performance from a discrete card, the AMD Radeon RX 6600 LE is the clear choice based on the recorded data. It wins both head-to-head tests by large margins: 38.8% in OpenCL and 46.1% in Vulkan. The Intel Arc A550M, with its 60 W TDP and IGP classification, targets a different segment entirely: portable devices where power efficiency is paramount. Its end-of-life production status further limits its appeal for new designs.

The data does not support choosing the Intel part for compute workloads. Even in the Vulkan test, where AMD's lead is its smallest, the 46.1% delta is overwhelming. However, the Intel card's lower power draw and integrated form factor mean it has a role in systems where a discrete GPU is not feasible. The AMD part requires a dual-slot footprint, an 8-pin connector, and a 300 W PSU, all of which are incompatible with ultra-portable designs.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the first data point. The AMD Radeon RX 6600 LE scores 69229, while the Intel Arc A550M scores 49894. The delta of 38.8% is substantial and reflects the combined effect of AMD's higher clocks, superior pixel rate, and greater FP32 throughput. AMD's 8.942 TFLOPS of FP32 performance outpaces Intel's 8.397 TFLOPS, and the clock advantage at boost (2495 MHz versus 2050 MHz) compounds the architectural lead.

The Geekbench Vulkan test widens the gap further. AMD scores 72428, Intel scores 49580, and the delta grows to 46.1%. This suggests AMD's RDNA 2.0 implementation handles Vulkan workloads particularly well relative to Intel's Xe-HPG. The FP16 numbers follow the same pattern: AMD delivers 17.88 TFLOPS (2:1) versus Intel's 16.79 TFLOPS (2:1).

Texture and pixel throughput reinforce the AMD advantage. AMD's texture rate of 279.4 GTexel/s exceeds Intel's 262.4 GTexel/s, and the pixel rate gap is wider still at 159.7 GPixel/s versus 131.2 GPixel/s. These are not marginal differences; they represent consistent wins across every measured metric in the database.

Where Each One Wins

The AMD Radeon RX 6600 LE wins in every benchmark category recorded. Its OpenCL score of 69229 and Vulkan score of 72428 both exceed the Intel Arc A550M's corresponding results by large margins. The card also holds advantages in pixel rate, texture rate, FP32, FP16, and both clock speeds. For any workload that relies on raw compute throughput, whether OpenCL or Vulkan, the data shows AMD as the superior performer. Its 91st percentile ranking versus Intel's 86th percentile confirms this at a global level.

The Intel Arc A550M wins in areas outside raw performance. Its 60 W TDP is less than half of AMD's 132 W, making it suitable for thermally constrained environments. Its IGP form factor means it can be integrated directly into portable devices, whereas the AMD card requires a dual-slot expansion slot, 190 mm of length, and an 8-pin power connector. Intel's PCIe 4.0 x16 interface provides double the lane width of AMD's x8 connection, which could matter in bandwidth-sensitive scenarios, though the benchmark data does not show a corresponding performance benefit. The larger transistor count and die size suggest more computational resources, but the lower clocks prevent those resources from translating into benchmark wins.

In practical terms, the AMD Radeon RX 6600 LE is the choice for desktop builds where performance is the priority and the power supply can handle a 300 W recommendation. The Intel Arc A550M suits mobile or integrated designs where the 60 W power envelope and lack of discrete connectors are decisive factors. The production status also matters: AMD's part is active and available, while Intel's is end-of-life, which affects long-term availability and driver support prospects.
