AMD Radeon RX 6550M vs Intel Arc A580 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive advantage for the Intel Arc A580 in every benchmark where both GPUs appear. Across two shared tests, the Arc A580 wins both, with no test favoring the AMD Radeon RX 6550M.

In Geekbench OpenCL, the Intel Arc A580 scores 91,657 points against 42,536 for the AMD Radeon RX 6550M. That is a 115.5% delta, meaning the Intel part more than doubles the AMD mobile GPU in this raw compute workload. The gap is enormous and consistent with the fundamental differences in scale between the two chips.

Geekbench Vulkan tells a similar story but with a narrower margin. The Arc A580 posts 79,381 points, while the RX 6550M manages 50,867. The delta here is 56.1%, still a commanding lead for Intel, but notably smaller than the OpenCL gap. This suggests the AMD architecture closes some ground under Vulkan's explicit API model, though it remains firmly behind.

The overall benchmark average reinforces this picture. The Intel Arc A580 carries an average benchmark score of 57,756 across all recorded tests, placing it in the 87th percentile of all GPUs in the database. The AMD Radeon RX 6550M averages 46,702, sitting in the 85th percentile. While both are above the median, the Arc A580's raw average is roughly 23.7% higher, a substantial margin that reflects its wins in the head-to-head tests.

Looking at nearest rivals provides additional context. The Arc A580's closest competitor by average score is the Intel Arc A570M at 58,239, which the A580 trails by 0.8%. It also sits 0.6% behind the AMD Radeon RX 5600 OEM (58,085) and 1.1% behind the AMD Radeon RX 6950 XT (58,392). Interestingly, the Arc A580 edges out the AMD Radeon RX 9070 GRE by 0.7%, despite that card's newer positioning. For the RX 6550M, its nearest rival is the Intel Arc A530M at 46,614, which it leads by just 0.2%. It also beats the AMD Radeon RX 5600M by 0.2%, the NVIDIA RTX A2000 by 1.4%, and the NVIDIA RTX 5880 Ada Generation by 1.6%. These tight margins around the RX 6550M indicate it sits in a crowded performance band, while the Arc A580's rivals are more spread out.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc A580 is built on the Xe-HPG architecture using the DG2-512 chip, part of the Alchemist generation within the Arc 5 family. It uses a 6 nm process from TSMC, integrating 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4M per mm².

The AMD Radeon RX 6550M employs RDNA 2.0 with the Navi 24 chip, hailing from the Navi Mobile generation within the RX 6000M series. It also uses TSMC's 6 nm node, but the die is dramatically smaller at 107 mm² with just 5,400 million transistors. Its transistor density is 50.5M per mm², slightly lower than Intel's.

These scale differences cascade through every compute unit. The Arc A580 packs 3,072 shading units, 192 texture mapping units, and 96 render output units. It also includes 24 ray tracing cores. The RX 6550M counters with 1,024 shading units, 64 TMUs, and 32 ROPs, plus 16 ray tracing cores. In every category, the Intel part has either three times the resources or double the ray tracing hardware.

Clock behavior diverges sharply. The RX 6550M runs a 2000 MHz base clock and boosts to 2840 MHz, with a game clock of 2560 MHz. The Arc A580 starts at 1700 MHz base and reaches 2000 MHz boost. Despite lower clocks, the Arc A580's massive resource count drives far higher throughput. Its FP32 peak is 12.29 TFLOPS versus 5.816 TFLOPS for the AMD part. Pixel fill rate stands at 192.0 GPixel/s for Intel versus 90.88 GPixel/s for AMD. Texture rate is 384.0 GTexel/s versus 181.8 GTexel/s.

Memory architecture is another chasm. The Arc A580 uses 8 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The RX 6550M has 4 GB of GDDR6 on a 64-bit bus, yielding just 144.0 GB/s. That is a 3.6x bandwidth advantage for Intel, which matters heavily in texture-heavy scenes and higher resolutions. The AMD part does run its memory faster at 2250 MHz (18 Gbps effective) versus 2000 MHz (16 Gbps effective) for Intel, but the narrow bus cannot compensate.

Power and physical design differ as expected for desktop versus mobile parts. The Arc A580 has a 175 W TDP, uses dual-slot cooling, and requires two 8-pin power connectors with a suggested 450 W PSU. The RX 6550M is an IGP-class mobile chip at 80 W TDP with no power connectors. Bus interface also differs: PCIe 4.0 x16 for Intel versus PCIe 4.0 x4 for AMD.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are identical on paper. Display outputs differ, with the Arc A580 offering 1x HDMI 2.1 and 3x DisplayPort 2.0, while the RX 6550M is portable device dependent.

Where Each One Wins

The Intel Arc A580 wins every recorded head-to-head test, so its advantages are straightforward. In Geekbench OpenCL, the 115.5% lead indicates a massive compute advantage that benefits GPU-accelerated workloads like rendering, physics simulations, and general compute tasks. The Vulkan win of 56.1% shows strong performance in modern game APIs and Vulkan-based applications.

The RX 6550M's strengths are not visible in the benchmark data, but its architecture suggests scenarios where it could be preferable. Its 80 W TDP and IGP form factor mean it fits in thin-and-light laptops, whereas the Arc A580 is a dual-slot desktop card requiring external power. The RX 6550M's higher boost clock of 2840 MHz versus 2000 MHz for Intel indicates it can sustain higher frequency headroom when power and thermal limits allow, which may help in short bursts of lightly threaded workloads.

For gaming specifically, the Arc A580's 8 GB VRAM and 512.0 GB/s bandwidth make it far more suitable for modern titles at 1080p or 1440p with high texture settings. The RX 6550M's 4 GB frame buffer and 144.0 GB/s bandwidth will hit walls in VRAM-hungry games, forcing lower quality settings or reduced resolutions. The Intel card's 24 ray tracing cores also provide more headroom for RT effects, though neither part is a ray tracing powerhouse.

Specification Differences

The two GPUs differ across nearly every measurable specification. The Arc A580 uses the DG2-512 chip with Xe-HPG architecture, while the RX 6550M uses Navi 24 with RDNA 2.0. Process nodes match at 6 nm TSMC, but transistor counts and die sizes diverge wildly: 21,700 million transistors on 406 mm² for Intel versus 5,400 million on 107 mm² for AMD.

Clock speeds favor AMD: 2000 MHz base and 2840 MHz boost versus 1700 MHz base and 2000 MHz boost for Intel. The RX 6550M also lists a game clock of 2560 MHz that the Arc A580 lacks. Memory clocks favor AMD as well, with 2250 MHz (18 Gbps effective) versus 2000 MHz (16 Gbps effective).

Memory capacity and bus width favor Intel decisively: 8 GB on a 256-bit bus versus 4 GB on a 64-bit bus. Bandwidth follows, 512.0 GB/s versus 144.0 GB/s. Compute resources all favor Intel: 3,072 shading units versus 1,024, 192 TMUs versus 64, 96 ROPs versus 32, and 24 RT cores versus 16.

Power figures are starkly different. The Arc A580 draws 175 W with dual-slot cooling and 2x 8-pin connectors, while the RX 6550M is an IGP at 80 W with no connectors. The suggested PSU for Intel is 450 W; AMD lists none. Bus interface differs: PCIe 4.0 x16 versus PCIe 4.0 x4. Display outputs are 1x HDMI 2.1 plus 3x DisplayPort 2.0 for Intel, versus portable device dependent for AMD.

Release dates differ by roughly nine months: the Arc A580 launched in October 2023, the RX 6550M in January 2023. The Arc A580's predecessor is Xe Graphics and its successor is Battlemage; the RX 6550M's predecessor is Polaris Mobile with no listed successor.

The Verdict

The data supports a clear choice for most use cases: the Intel Arc A580 is the stronger GPU by every recorded metric. It wins both head-to-head benchmarks, holds a 23.7% higher average benchmark score, and offers 8 GB VRAM with 512.0 GB/s bandwidth versus 4 GB and 144.0 GB/s on the AMD part. For desktop gaming, compute workloads, or any task that benefits from raw throughput, the Arc A580 is the obvious pick.

The AMD Radeon RX 6550M is not without a role, but its strengths lie outside the benchmark scores. As an 80 W IGP with no power connectors, it fits into mobile chassis where the Arc A580 cannot physically go. Its higher boost clock of 2840 MHz suggests it can ramp quickly in power-constrained environments. If the requirement is a compact, low-power laptop GPU rather than a desktop card, the RX 6550M is the only viable option between these two.

However, the performance gap is too large to ignore. The 115.5% OpenCL delta and 56.1% Vulkan delta mean the RX 6550M will struggle in any compute-heavy or graphically demanding scenario. Its 4 GB VRAM is a hard limit for modern games at higher settings. The Arc A580's 87th percentile standing versus the RX 6550M's 85th percentile, combined with its commanding benchmark wins, makes it the superior choice wherever desktop power delivery and cooling are available.
