AMD Radeon Pro 460 vs Intel Arc A770M Comparison

Intel Arc A770M and AMD Radeon Pro 460 are two very different mobile graphics solutions, separated by a wide gulf in both era and performance class. The data shows the Intel part decisively outperforms the AMD part in every directly comparable benchmark, making this a one-sided comparison in raw compute and graphics tasks. The Radeon Pro 460, however, carves out a niche through its extremely low power draw and legacy API support, making it suitable for specific, older workloads.

The Verdict

The verdict from the benchmark data is unambiguous: the Intel Arc A770M is the superior GPU for virtually any modern, demanding task. It holds a massive 485.5% lead over the AMD Radeon Pro 460 in Geekbench OpenCL (89494 vs 15284) and a 342.6% lead in Geekbench Vulkan (74422 vs 16816). The Arc A770M's average benchmark score of 18383 places it at the 62nd percentile of all GPUs, while the Radeon Pro 460's average of 17509 sits at the 61st percentile. While their percentile rankings are close, the actual performance delta in head-to-head tests is enormous, indicating the Radeon Pro 460's percentile is buoyed by a different benchmark set.

The AMD Radeon Pro 460 should only be considered by users whose absolute primary constraint is power consumption. With a TDP of 35 W compared to the Arc A770M's 120 W, it is designed for ultra-low-power, thin-and-light systems. For tasks that predate modern APIs, its support for DirectX 12 (12_0) and Vulkan 1.3 might be sufficient, but its performance ceiling is drastically lower. The data shows it is not a competitor in the same performance class as the Arc A770M. The Arc A770M is the clear choice for gaming, content creation, or any compute-heavy workload where performance is the priority.

Where Each One Wins

The Intel Arc A770M wins in every single category where both parts have a shared benchmark. Its victories are not marginal; they are overwhelming.

• Compute and Modern Graphics: The Arc A770M's 16.79 TFLOPS of FP32 performance and 33.59 TFLOPS of FP16 performance dwarf the Radeon Pro 460's 1.858 TFLOPS in both categories. This translates to a 485.5% lead in the Geekbench OpenCL compute test and a 342.6% lead in the Geekbench Vulkan test. For any modern rendering, machine learning inference, or GPU-accelerated compute, the Arc A770M is the only viable option here.
• Memory Bandwidth and Capacity: The Arc A770M has a 16 GB GDDR6 memory pool on a 256-bit bus, delivering 512.0 GB/s of bandwidth. The Radeon Pro 460 has 4 GB of GDDR5 on a 128-bit bus, providing only 81.28 GB/s. This 6.3x difference in bandwidth means the Arc A770M can feed its 4096 shading units at a much higher rate, avoiding bottlenecks in texture-heavy and high-resolution scenarios.
• The AMD Radeon Pro 460's Only "Win": The Radeon Pro 460's sole advantage is its power efficiency. At 35 W TDP, it uses less than a third of the power of the Arc A770M (120 W). This makes it a candidate for passively cooled or ultra-portable systems where battery life and heat generation are more critical than raw performance. It also has a native Geekbench Metal score of 20426, a benchmark the Intel part does not have, indicating its intended use in Apple's ecosystem.

Architecture Differences

The two GPUs represent fundamentally different architectural and manufacturing approaches.

• Process Node and Die Size: The Intel Arc A770M is built on a modern 6 nm process at TSMC, packing 21,700 million transistors into a 406 mm² die. In contrast, the AMD Radeon Pro 460 uses an older 14 nm process from GlobalFoundries, with only 3,000 million transistors on a 123 mm² die. This results in a transistor density of 53.4M / mm² for Intel versus 24.4M / mm² for AMD, showing a massive generational leap in manufacturing efficiency.
• Core Configuration: The Arc A770M features 4096 shading units, 256 TMUs, and 128 ROPs, along with 32 dedicated ray tracing cores. The Radeon Pro 460 has 1024 shading units, 64 TMUs, and only 16 ROPs, with no ray tracing cores at all. This 4x difference in shading units and 8x difference in ROPs directly explains the large performance gap in fill-rate and pixel throughput.
• Memory Subsystem: The Arc A770M uses 16 GB of GDDR6 memory with a 256-bit interface. The Radeon Pro 460 uses 4 GB of GDDR5 with a 128-bit interface. The Arc's memory clock is 2000 MHz (16 Gbps effective) versus the Radeon's 1270 MHz (5.1 Gbps effective). This combination of wider bus and faster memory gives the Intel part a 512.0 GB/s bandwidth versus 81.28 GB/s.
• API and Feature Support: The Arc A770M supports the latest DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Radeon Pro 460 is limited to DirectX 12 (12_0) and Vulkan 1.3. This means the Intel GPU can leverage advanced features like hardware ray tracing and variable rate shading, which are not available on the AMD part. Both support OpenGL 4.6.

Head-to-Head Benchmarks

The two directly comparable benchmarks in the data paint a clear picture of the performance hierarchy.

• Geekbench OpenCL: This is the most lopsided result. The Intel Arc A770M scores 89494, while the AMD Radeon Pro 460 scores just 15284. This represents a 485.5% advantage for the Intel part. This delta is attributable to the Arc's 4096 shading units, 16.79 TFLOPS FP32 compute, and 512.0 GB/s of bandwidth, which are all orders of magnitude higher than the Radeon's 1024 shading units, 1.858 TFLOPS, and 81.28 GB/s. The result shows that for compute-heavy tasks, the Radeon Pro 460 is not in the same league.
• Geekbench Vulkan: The Intel Arc A770M again wins decisively with a score of 74422 versus the AMD Radeon Pro 460's 16816. The 342.6% lead for Intel reflects not only its raw compute advantage but also its superior API support (Vulkan 1.4 vs 1.3) and higher memory bandwidth. This benchmark indicates that the Arc A770M will provide a significantly smoother experience in Vulkan-based games and applications.

There are no head-to-head benchmarks where the AMD Radeon Pro 460 wins. Its only unique benchmark is a Geekbench Metal score of 20426, for which the Intel Arc A770M has no corresponding result. While this shows the Radeon Pro 460 has a functional Metal driver, it does not offer any basis for comparison with the Intel part. In every shared test, the Intel Arc A770M's average benchmark score of 18383, despite being dragged down by lower legacy scores, still exceeds the Radeon Pro 460's average of 17509. The data suggests that the Arc A770M is not merely faster; it is in a different performance tier altogether.
