Architecture Differences

The AMD Radeon RX 6550M is built on the RDNA 2.0 architecture using the Navi 24 chip, manufactured on a 6 nm process at TSMC. It belongs to the Navi Mobile (RX 6000M) generation. The Intel Arc B770 uses the Xe2-HPG architecture with the BMG-G31 chip, manufactured on a 5 nm process, also at TSMC, and belongs to the Battlemage (Arc 7) generation.

The process node difference is significant: 6 nm for AMD versus 5 nm for Intel. The AMD chip packs 5,400 million transistors into a 107 mm² die, giving a density of 50.5M transistors per mm². The Intel chip's transistor count is not recorded, but its die size is 368 mm², which is 3.44 times larger than the AMD die.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part uses a PCIe 4.0 x4 interface, while the Intel part uses PCIe 4.0 x16, providing eight times the lane count for data transfer. The AMD card is an IGP form factor with portable device dependent display outputs, whereas the Intel card is a dual-slot design with 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

The Intel Arc B770 carries 16 ray tracing cores, double the 16 on the AMD Radeon RX 6550M. The AMD part has 1024 shading units, 64 texture mapping units, and 32 render output units. The Intel part has 4096 shading units, 256 texture mapping units, and 128 render output units.

The AMD Radeon RX 6550M has a game clock of 2560 MHz, a feature the Intel Arc B770 does not list. The memory clocks differ as well: AMD runs at 2250 MHz with 18 Gbps effective, while Intel runs at 2000 MHz with 16 Gbps effective.

Head-to-Head Benchmarks

The recorded benchmark data shows the AMD Radeon RX 6550M with a Geekbench OpenCL score of 42536 and a Geekbench Vulkan score of 50867. The average benchmark score for the AMD part is 46702. The Intel Arc B770 has no recorded benchmark scores in the database, with an average benchmark score of 0.

The AMD Radeon RX 6550M sits at the 85th percentile of all GPUs in the database. Its nearest rivals include the Intel Arc A530M with an average score of 46614, just 0.2% behind, and the AMD Radeon RX 5600M at 46601, also 0.2% behind. The NVIDIA RTX A2000 scores 46043, 1.4% lower, and the NVIDIA RTX 5880 Ada Generation scores 45972, 1.6% lower.

With no head-to-head benchmark results recorded between the two cards and no wins recorded for either side, the direct comparison relies on the specification data and the AMD part's measured scores. The Intel Arc B770's 50th percentile ranking, based on its position in the database, indicates it has not yet demonstrated performance through recorded measurements.

The AMD part's average benchmark score of 46702 places it in a competitive tier with the Intel Arc A530M and the AMD Radeon RX 5600M, all within 0.2% of each other. The gap to the NVIDIA RTX A2000 is 1.4%, and to the RTX 5880 Ada Generation it is 1.6%, showing the RX 6550M holds a slight edge over those NVIDIA parts in the recorded data.

Given the Intel Arc B770's lack of benchmark scores, the data cannot confirm its actual performance level. The specification sheet suggests substantially higher compute throughput, but without measurements, the database cannot verify how that translates into real-world results.

The AMD Radeon RX 6550M has a higher boost clock by 440 MHz and a higher game clock that Intel does not list. The AMD part also has a higher memory clock in both MHz and effective data rate. The AMD card uses no power connectors and carries an 80 W TDP, while the Intel card requires a 550 W suggested PSU and uses a 6-pin plus 8-pin connector setup.

The Verdict

The data indicates two GPUs aimed at different segments. The AMD Radeon RX 6550M is a low-power mobile part with an 80 W TDP, IGP form factor, and 4 GB of memory. Its recorded benchmark scores place it at the 85th percentile of all GPUs, with an average score of 46702 that sits within 0.2% of the Intel Arc A530M and AMD Radeon RX 5600M.

The Intel Arc B770 is a desktop-class dual-slot card with a 225 W TDP, 16 GB of memory, and significantly higher raw specifications across every compute metric. Its FP32 throughput of 19.66 TFLOPS is over three times the AMD part's 5.816 TFLOPS. However, the database contains no benchmark scores for the Intel card, so its actual measured performance cannot be confirmed.

For systems constrained by power and space, the AMD Radeon RX 6550M's 80 W TDP and IGP slot width make it suitable for compact mobile platforms. Its boost clock of 2840 MHz is the highest of the two, and its measured Vulkan score of 50867 shows it handles graphics workloads effectively within its class.

For systems with adequate power delivery and cooling, the Intel Arc B770 offers a dramatically larger memory pool, a wider memory bus, and substantially higher compute and texture rates. The 512.0 GB/s bandwidth is 3.56x the AMD part's 144.0 GB/s, which matters for high-resolution textures and large datasets.

The production status of the AMD part is listed as Active, while the Intel part's production status is not recorded. The release dates show the AMD card launched in January 2023, while the Intel card's release date is listed as December 2025.
