The Verdict

The benchmark data is unambiguous about the overall hierarchy: the Intel Arc A770M wins 7 of the 9 head-to-head tests, and its average benchmark score of 18383 is 17.2% higher than the W5500's 15679. The Arc A770M's percentile placement at 62 versus 58 further confirms its position above the AMD part in the broader GPU landscape.

For users prioritizing raw graphics throughput, modern API support, and large memory capacity, the Intel Arc A770M is the clear choice. Its 31.1% lead in Passmark G3D and 79.5% lead in DirectX 12 underline a decisive advantage in mainstream 3D rendering workloads. The 16 GB memory allocation, double that of the W5500, also provides a substantial capacity cushion for texture-heavy or data-intensive scenes.

The AMD Radeon Pro W5500, however, retains relevance in two specific areas. Its 11.8% win in Passmark G2D suggests better 2D rasterization performance, which can matter in desktop composition and certain professional 2D applications. Its near-tie in Passmark GPU Compute, 4804 versus 4778, shows that compute-focused tasks do not follow the same pattern as graphics workloads. Additionally, the W5500 is a single-slot card with four DisplayPort 1.4a outputs, making it a more straightforward fit for multi-display professional setups where physical configuration matters more than raw frame rates.

The verdict: choose the Intel Arc A770M for maximum graphics performance, higher API feature levels, and double the memory. Choose the AMD Radeon Pro W5500 if 2D performance, single-slot physical design, or a 6-pin power configuration are decisive factors, or if the workload is compute-bound where the two cards are effectively matched.

Head-to-Head Benchmarks

The largest win for the Intel Arc A770M comes in Geekbench OpenCL, where it scores 89494 against 45615, a 96.2% advantage. This nearly doubles the AMD card's compute throughput in that test. The pattern continues in Geekbench Vulkan, where Intel leads 74422 to 42021, a 77.1% gap.

In DirectX legacy and modern tests, the Arc A770M is consistently ahead. Passmark DirectX 12 shows 70 versus 39, a 79.5% lead. Passmark DirectX 9 shows 178 versus 126, a 41.3% lead. Passmark DirectX 11 shows 69 versus 56, a 23.2% lead. Passmark DirectX 10 shows 56 versus 47, a 19.1% lead. The Arc A770M's advantage narrows as the API generation gets older, but it remains positive across all four DirectX tests.

The Passmark G3D test, a general 3D graphics benchmark, favors Intel by 31.1%, with scores of 11774 versus 8978. This aligns with the DirectX results and reinforces that the Intel part delivers substantially higher graphics throughput in typical 3D scenarios.

The AMD Radeon Pro W5500 claims two wins. The first is Passmark G2D, where it scores 806 versus 711, an 11.8% margin. The second is Passmark GPU Compute, where it scores 4804 versus 4778, a razor-thin 0.5% edge. These two wins are isolated to 2D rasterization and a specific compute benchmark, respectively, and do not offset the Intel card's dominance elsewhere.

Overall, the head-to-head record is 7 wins for the Intel Arc A770M and 2 for the AMD Radeon Pro W5500. The magnitude of Intel's wins, particularly the 96.2% OpenCL and 77.1% Vulkan margins, far exceeds the slim 0.5% AMD advantage in GPU Compute.

Specification Differences

The two cards differ across nearly every major specification category.

Memory capacity differs by a factor of two: the Intel Arc A770M has 16 GB of GDDR6, while the AMD Radeon Pro W5500 has 8 GB. Bus width also differs, with Intel using a 256-bit interface versus AMD's 128-bit. This drives a bandwidth gap of 512.0 GB/s versus 224.0 GB/s, a 2.3x difference in favor of Intel.

Clock speeds show a different pattern. The AMD card has a higher base clock at 1744 MHz versus 1650 MHz, and a lower boost clock at 1855 MHz versus 2050 MHz. Memory clocks also differ: Intel runs at 2000 MHz with 16 Gbps effective, while AMD runs at 1750 MHz with 14 Gbps effective.

Shading resources are heavily skewed toward Intel. The Arc A770M has 4096 shading units, 256 TMUs, and 128 ROPs. The W5500 has 1408 shading units, 88 TMUs, and 32 ROPs. The Intel card also includes 32 ray tracing cores, which the AMD card lacks entirely.

Rasterization and texture throughput follow the same trend. Intel's pixel rate is 262.4 GPixel/s versus 59.36 GPixel/s for AMD. Intel's texture rate is 524.8 GTexel/s versus 163.2 GTexel/s. FP32 compute is 16.79 TFLOPS versus 5.224 TFLOPS, and FP16 is 33.59 TFLOPS versus 10.45 TFLOPS, both at a 2:1 ratio.

Power and physical design differ as well. The Intel card is rated at 120 W TDP and is an IGP, meaning it is integrated into a platform. The AMD card is rated at 125 W TDP, is a single-slot card measuring 241 mm by 111 mm, and requires a single 6-pin power connector with a 300 W suggested power supply.

Bus interface and display outputs also differ. Intel uses PCIe 4.0 x16 with display outputs described as "Portable Device Dependent." AMD uses PCIe 4.0 x8 and provides four DisplayPort 1.4a outputs.

Architecture Differences

The Intel Arc A770M is built on Intel's Xe-HPG architecture, specifically the Alchemist generation for Arc 7 Mobile. It uses the DG2-512 chip fabricated on a 6 nm process at TSMC, with 21,700 million transistors on a 406 mm² die, giving a transistor density of 53.4M per mm².

The AMD Radeon Pro W5500 uses the RDNA 1.0 architecture, part of the Radeon Pro Navi generation. It is built on the Navi 14 chip using a 7 nm process at TSMC, with 6,400 million transistors on a 158 mm² die, yielding a transistor density of 40.5M per mm².

The Intel chip is more than three times larger in both transistor count and die area. It also has a higher transistor density, 53.4M per mm² versus 40.5M per mm², indicating a more compact arrangement of transistors despite the larger total count.

Feature support differs in API level. The Intel Arc A770M supports DirectX 12 Ultimate (12_2), while the AMD Radeon Pro W5500 supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The presence of 32 ray tracing cores on the Intel card is a defining architectural difference, as the AMD card has no ray tracing cores listed.

Both cards are end-of-life products. The AMD Radeon Pro W5500 has a release date of 2020-02-09 and lists the Radeon Pro Vega as its predecessor. Its launch MSRP was 399 USD. The Intel Arc A770M has no release date or predecessor listed in the database.
