AMD Radeon RX 5600 XT vs Intel Arc A770M Comparison

The Verdict

The benchmark data splits these two GPUs cleanly by workload type. The AMD Radeon RX 5600 XT wins 6 of the 10 head-to-head tests, while the Intel Arc A770M wins 4. However, the Intel part wins the modern, API-heavy tests that matter most for current and upcoming games, while the AMD card dominates legacy DirectX and compute workloads.

For gamers targeting DirectX 12 Ultimate titles, the Intel Arc A770M is the stronger pick. Its 3DMark Steel Nomad DX12 score of 2278 beats the AMD card's 1669 by 26.7%. The gap repeats in Geekbench Vulkan, where Intel leads 74422 to 56218, a 24.5% advantage. The Arc A770M also wins PassMark DirectX 12 by 25.7% (70 vs 52). If your library is built around modern APIs, the Intel part is clearly ahead.

For users running older DirectX 9/10/11 titles, the RX 5600 XT is the better choice. It wins PassMark DirectX 11 by 39.1% (96 vs 69), DirectX 10 by 30.4% (73 vs 56), and DirectX 9 by 13.5% (202 vs 178). The AMD card also leads in PassMark G3D (13457 vs 11774, a 14.3% margin) and PassMark GPU Compute (6296 vs 4778, a 31.8% margin). If legacy API support or compute throughput is the priority, the AMD card is the safer bet.

The overall average benchmark score favors AMD: 20713 versus 18383 for Intel. The AMD card sits at the 66th percentile among all GPUs, while the Intel part lands at the 62nd percentile. The RX 5600 XT's nearest rivals include the Intel Arc A750 (0.6% behind) and the Intel Arc B570 (0.8% behind), while the Arc A770M's closest competitor is the AMD Radeon RX 460 (0.1% behind). This suggests the AMD card competes in a slightly higher performance tier overall.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The RX 5600 XT uses AMD's RDNA 1.0 architecture on a 7 nm TSMC process, built around the Navi 10 chip. It packs 10,300 million transistors on a 251 mm² die, giving a transistor density of 41.0 million per mm². The Arc A770M uses Intel's Xe-HPG architecture on a 6 nm TSMC process, based on the DG2-512 chip. It contains 21,700 million transistors across a 406 mm² die, for a density of 53.4 million per mm². The Intel chip is more than twice as dense in transistor count and roughly 60% larger in die area.

The shader configuration differs dramatically. The RX 5600 XT has 2304 shading units, 144 texture mapping units, and 64 render output units. The Arc A770M has 4096 shading units, 256 TMUs, and 128 ROPs, exactly double in each category. The Intel part also includes 32 ray tracing cores, which the AMD card lacks entirely. This explains the Intel card's higher theoretical pixel rate of 262.4 GPixel/s versus 99.84 GPixel/s for AMD, and its texture rate of 524.8 GTexel/s versus 224.6 GTexel/s.

Memory configurations diverge as well. The RX 5600 XT ships with 6 GB of GDDR6 on a 192-bit bus, delivering 288.0 GB/s of bandwidth. The Arc A770M offers 16 GB of GDDR6 on a 256-bit bus, more than doubling bandwidth to 512.0 GB/s. The Intel card's memory clock runs at 2000 MHz (16 Gbps effective) versus 1500 MHz (12 Gbps effective) for AMD.

Clock speeds favor Intel on paper. The Arc A770M has a base clock of 1650 MHz and a boost of 2050 MHz. The RX 5600 XT starts lower at 1130 MHz base, boosts to 1560 MHz, with a game clock of 1375 MHz. Despite the lower clocks, AMD's FP32 throughput of 7.188 TFLOPS is less than half of Intel's 16.79 TFLOPS. FP16 follows the same pattern: 14.38 TFLOPS for AMD versus 33.59 TFLOPS for Intel.

Power characteristics are notable. The RX 5600 XT has a TDP of 150 W and requires a 450 W power supply with a single 8-pin connector. The Arc A770M draws only 120 W despite its larger chip, and is classified as an IGP (integrated graphics processor) with no power connector listed. This makes the Intel part more efficient per watt, at least on paper. The AMD card is a dual-slot design with a 267 mm (10.5 inches) length, while the Intel part has no listed dimensions.

The RX 5600 XT supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The Arc A770M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The DirectX 12 Ultimate designation indicates the Intel card supports the full feature set including ray tracing, which aligns with its 32 dedicated RT cores.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test shows the largest modern-API gap. The Intel Arc A770M scores 2278 versus 1669 for the AMD Radeon RX 5600 XT, a 26.7% advantage. This test stress-tests DirectX 12 rendering, and the Intel card's additional shading units and ray tracing cores likely contribute to the margin.

Geekbench results follow the same pattern. In OpenCL, the Arc A770M scores 89494 against 68537 for the RX 5600 XT, a 23.4% lead. In Vulkan, the Intel card scores 74422 versus 56218, a 24.5% gap. These compute-oriented benchmarks align with the Intel part's doubled shader count and higher theoretical FP32 throughput.

PassMark DirectX 12 reverses the trend slightly. The Intel card wins 70 to 52, a 25.7% margin. This is the only DirectX 12 test in the set, and it confirms the Intel part's advantage in the modern API.

The AMD Radeon RX 5600 XT takes every legacy DirectX test. PassMark DirectX 11 shows the biggest gap: AMD scores 96 versus 69 for Intel, a 39.1% difference. DirectX 10 follows with 73 versus 56, a 30.4% margin. DirectX 9 is closer but still decisive: 202 versus 178, a 13.5% lead for AMD.

PassMark G2D (2D graphics) favors AMD by 22.4% (870 vs 711). This is a less computationally intensive workload, and the AMD card's higher clock efficiency may explain the result. PassMark G3D (3D graphics) also goes to AMD: 13457 versus 11774, a 14.3% margin.

The compute tests split oddly. PassMark GPU Compute strongly favors AMD, with 6296 versus 4778, a 31.8% lead. This is surprising given Intel's higher theoretical FP32 and FP16 throughput, but the benchmark results are what they are. The AMD card's RDNA 1.0 architecture appears to handle this specific compute workload more efficiently.

Overall, the pattern is clear. The Intel Arc A770M wins the future-facing tests: 3DMark Steel Nomad, Geekbench OpenCL, Geekbench Vulkan, and PassMark DirectX 12. The AMD Radeon RX 5600 XT wins the legacy and 2D/3D tests: DirectX 9, 10, 11, G2D, G3D, and GPU Compute. The AMD card wins 6 of 10 head-to-head matchups, but the Intel card's wins are in the APIs that modern games use. The average benchmark score favors AMD by 12.7% (20713 vs 18383), but that average includes many legacy tests where AMD dominates. For a forward-looking purchase, the Intel Arc A770M offers better performance on the newest APIs and more than double the memory. For a backward-compatible system running older software, the RX 5600 XT delivers superior results.
