GPU Comparison

The Intel Arc A770M and AMD Radeon RX 7600 XT are two 16 GB graphics solutions aimed at different segments of the market, with the former being an end-of-life mobile part and the latter an active desktop card. Benchmark results show a clear split in performance characteristics, with the AMD card winning 8 of the 10 head-to-head comparisons, but the Intel part delivering a decisive victory in specific API workloads. The average benchmark scores place the Intel card at 18383 and the AMD at 17083, a difference of about 7.6% in favor of Intel, though this aggregate figure is heavily influenced by one outlier test.

Head-to-Head Benchmarks

The most dramatic divergence in the data appears in the Geekbench Vulkan test, where the Intel Arc A770M scores 74422 against the AMD Radeon RX 7600 XT’s 48366. This represents a 53.9% delta in Intel’s favor, making it the single largest performance gap in either direction across all tested workloads. This result is particularly striking because the AMD card wins the OpenCL variant of the same benchmark suite, scoring 92426 versus Intel’s 89494, a 3.2% margin. The Vulkan result suggests that the Intel architecture has a significant advantage in this specific API path, while the AMD part excels in the more general-purpose compute interface.

Outside of the Vulkan test, the AMD Radeon RX 7600 XT dominates the remainder of the benchmark suite. In PassMark’s DirectX 11 test, the AMD card scores 167 against Intel’s 69, yielding a 58.7% delta, the largest win for AMD in the entire comparison. The DirectX 10 test shows a similar trend, with AMD leading 85 to 56, a 34.1% margin. The older DirectX 9 workload also favors AMD, with scores of 228 versus 178, a 21.9% advantage. These results indicate that AMD holds a substantial lead in legacy DirectX API performance, which may be relevant for users running older titles or applications that rely on these interfaces.

In the more modern DirectX 12 path, the results are much closer. The 3DMark Steel Nomad DX12 test shows AMD winning with 2348 points against Intel’s 2278, a narrow 3% delta. However, the PassMark DirectX 12 test flips the result, with Intel scoring 70 and AMD scoring 65, giving Intel a 7.7% edge. This split suggests that the two cards are competitive in DirectX 12 workloads, with the specific test methodology determining the winner. The 3DMark result is likely the more representative of actual gaming performance, given its use of a modern game-like scene.

The compute-oriented workloads heavily favor AMD. In PassMark GPU Compute, the AMD Radeon RX 7600 XT scores 8987 compared to Intel’s 4778, a 46.8% delta. This is the second-largest margin in the entire comparison and indicates a significant advantage in general-purpose compute tasks. The Geekbench OpenCL result, while closer at 3.2%, still favors AMD, reinforcing the pattern that the AMD architecture is stronger in compute-heavy applications. The PassMark G2D test also goes to AMD, with scores of 1030 versus 711, a 31% difference, suggesting better 2D graphics performance.

The PassMark G3D test, which aggregates DirectX and OpenGL performance into a single metric, shows AMD winning decisively with 17132 points against Intel’s 11774, a 31.3% delta. This is the most comprehensive gaming-oriented score in the PassMark suite and reinforces AMD’s overall advantage in traditional rasterization workloads. Interestingly, the Intel Arc A770M’s nearest rival list includes the AMD Radeon Pro 5700 at a 1.1% delta and the NVIDIA GeForce RTX 3060 Mobile at 1.2%, while the AMD RX 7600 XT’s rivals include the NVIDIA GeForce RTX 3070 at -0.7%, indicating that these two cards are positioned in different performance tiers relative to their respective competition.

The Verdict

The data presents a clear split personality for these two cards. The AMD Radeon RX 7600 XT is the stronger all-around performer, winning 8 out of 10 benchmarks, with particularly large margins in DirectX 11 (58.7%), GPU Compute (46.8%), and DirectX 10 (34.1%). For users prioritizing legacy API compatibility, compute workloads, or general 3D gaming performance, the AMD card is the obvious choice based on the benchmark evidence. Its PassMark G3D score of 17132 is 45.5% higher than Intel’s 11774, and its GPU Compute score is nearly double.

The Intel Arc A770M has a narrow but distinct niche. Its 53.9% victory in Geekbench Vulkan is the largest single win in the entire comparison, and it also edges out AMD in PassMark DirectX 12 by 7.7%. For users who specifically need Vulkan performance, particularly in applications that heavily leverage this API, the Intel card offers a substantial advantage. However, this single bright spot is outweighed by AMD’s dominance across the board, making the Intel card a specialized choice rather than a general-purpose recommendation.

The average benchmark scores tell a slightly different story, with Intel at 18383 and AMD at 17083, a 7.6% difference in Intel’s favor. This discrepancy is driven by the Vulkan score’s influence on the average, which inflates Intel’s overall standing despite its losses in the majority of tests. The percentile rankings are nearly identical, with Intel at 62 and AMD at 60, indicating that both cards sit in the same general performance tier relative to all GPUs. The AMD Radeon RX 7600 XT is the better pick for most users, while the Intel Arc A770M is only preferable in Vulkan-centric workloads.

Where Each One Wins

The AMD Radeon RX 7600 XT wins in the majority of scenarios, particularly those involving legacy DirectX APIs. Its 58.7% lead in DirectX 11 and 34.1% lead in DirectX 10 make it the clear choice for older games and applications that rely on these interfaces. The 21.9% advantage in DirectX 9 further reinforces this pattern. For compute-heavy tasks, the AMD card’s 46.8% lead in GPU Compute and 3.2% lead in OpenCL make it the superior option for rendering, scientific computing, and other general-purpose workloads. The 31.3% advantage in PassMark G3D and 3% lead in 3DMark Steel Nomad DX12 indicate that for modern gaming, the AMD card is generally faster.

The Intel Arc A770M has a clear win in Vulkan performance, with its 53.9% lead in Geekbench Vulkan being the standout result. This makes it the better choice for applications that are heavily optimized for the Vulkan API, such as certain game engines, emulators, or professional tools that leverage Vulkan compute. The 7.7% win in PassMark DirectX 12 also gives it a narrow edge in that specific benchmark, though the 3DMark result favors AMD. The Intel card’s higher pixel rate of 262.4 GPixel/s versus 176.3 GPixel/s suggests it may have an advantage in fill-rate-bound scenarios, though this is not directly reflected in the benchmark scores.
