AMD Radeon RX 7700 vs Intel Arc A770M Comparison

Where Each One Wins

The benchmark data is unambiguous in this matchup. Across every recorded test in the database, the AMD Radeon RX 7700 takes the win. The Intel Arc A770M does not secure a single head-to-head victory among the nine shared benchmarks. That is a 0 to 9 sweep. The recorded data shows the AMD part ahead in every category, from modern DirectX 12 workloads to legacy DirectX 9, from compute-heavy OpenCL to pure 2D rendering.

The Intel Arc A770M's strongest relative showing comes in the 3DMark Steel Nomad test, where it trails by 20.5%. Its weakest relative position is in PassMark's DirectX 11 test, where the AMD card is ahead by 62.9%. The pattern is consistent: the gap widens as the workload leans on raw throughput and driver maturity. The Arc A770M is a mobile integrated GPU with a 120 W TDP, while the RX 7700 is a dual-slot desktop card with a 200 W TDP, and the performance delta reflects that positioning.

For users prioritizing portability and power efficiency, the Arc A770M has an obvious appeal, but the database shows no benchmark category where it outpaces the RX 7700. The AMD card wins the compute tests by a wide margin: PassMark GPU Compute shows a 56.4% deficit for Intel, and Geekbench OpenCL shows a 15.6% deficit. Even in the 2D test, where the Arc's 711 score is respectable for a mobile part, the RX 7700's 1206 score is 41% higher. The use-case conclusion is simple: the RX 7700 is the performance choice across all measured workloads, while the A770M competes on form factor and power envelope rather than speed.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. The Intel Arc A770M is built on the Xe-HPG architecture, codename DG2-512, part of the Alchemist generation for Arc 7 Mobile. It uses a 6 nm process at TSMC with 21,700 million transistors on a 406 mm² die, yielding a transistor density of 53.4 million per mm². The AMD Radeon RX 7700 uses RDNA 3.0, chip Navi 32, codename Wheat Nas, part of the Navi III series. It is fabricated on a 5 nm process at TSMC with 28,100 million transistors on a 346 mm² die, giving a density of 81.2 million per mm².

The shader configuration diverges sharply. The Intel part has 4096 shading units, 256 TMUs, and 128 ROPs, with 32 ray tracing cores. The AMD part has 2560 shading units, 160 TMUs, and 96 ROPs, but 40 ray tracing cores. This is a notable split: AMD achieves higher ray tracing core count with fewer total shaders. The FP32 compute figures reflect this: the RX 7700 delivers 25.18 TFLOPS, while the A770M delivers 16.79 TFLOPS. The FP16 numbers tell a different story, however. Intel reaches 33.59 TFLOPS with a 2:1 ratio, while AMD matches its FP32 at 25.18 TFLOPS with a 1:1 ratio. That means the Intel part has higher peak half-precision throughput, though the AMD part wins in full-precision workloads.

Memory architecture is similar on paper but different in performance. Both use 16 GB of GDDR6 on a 256-bit bus. The Intel part runs at 2000 MHz with 16 Gbps effective, producing 512.0 GB/s of bandwidth. The AMD part runs at 2438 MHz with 19.5 Gbps effective, producing 624.1 GB/s, a 21.9% bandwidth advantage. Clock speeds also favor AMD: 1900 MHz base and 2459 MHz boost versus Intel's 1650 MHz base and 2050 MHz boost. The AMD part also has a game clock of 2041 MHz, which the Intel part does not list.

The physical and electrical profiles are completely different. The Arc A770M is an IGP (integrated graphics processor) with no slot width, no power connectors, and a 120 W TDP. The RX 7700 is a dual-slot card measuring 267 mm by 135 mm by 50 mm, requiring two 8-pin power connectors and a 550 W suggested PSU. Both use PCIe 4.0 x16. API support is identical: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel part's display outputs are listed as "Portable Device Dependent," while the AMD card has 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C.

Head-to-Head Benchmarks

The largest single win for the AMD Radeon RX 7700 comes in PassMark's DirectX 11 test. The AMD card scores 186 against Intel's 69, a delta of 62.9%. This is a legacy API workload, and the gap suggests the Intel driver stack has not reached parity on older DirectX paths. The second-largest margin is in PassMark GPU Compute, where AMD scores 10963 versus Intel's 4778, a 56.4% deficit for the Arc part. This is a raw compute test that favors the RX 7700's higher FP32 throughput and bandwidth.

The PassMark G3D test shows a 43.9% gap: AMD at 20974, Intel at 11774. This is the overall 3D gaming metric, and it confirms the direction of the other tests. The PassMark G2D test shows a 41% gap: AMD at 1206, Intel at 711. Even in 2D, the desktop card's higher pixel rate and memory bandwidth show through. The DirectX 10 test shows AMD ahead by 39.1% (92 versus 56), and DirectX 9 shows AMD ahead by 31.8% (261 versus 178). The DirectX 12 test shows AMD ahead by 27.1% (96 versus 70).

The two modern API tests narrow the gap. In 3DMark Steel Nomad, the RX 7700 scores 2865 against Intel's 2278, a 20.5% lead. In Geekbench OpenCL, AMD scores 106028 against Intel's 89494, a 15.6% lead. These are the closest margins in the entire dataset, but they still favor AMD. The pattern across all nine tests is consistent: AMD wins every single benchmark, with margins ranging from 15.6% to 62.9%. The Intel part never comes within single digits of the AMD card.

The Geekbench Vulkan test is notable because it only appears in the Intel item's benchmark list, not in the head-to-head set. The Arc A770M scores 74422 there. The AMD item does not list a Vulkan score, so no direct comparison is possible from the recorded data.
