AMD Radeon RX 7600S vs Intel Arc A770M Comparison

Head-to-Head Benchmarks

The recorded data presents a split decision between the Intel Arc A770M and the AMD Radeon RX 7600S, with the AMD card winning 6 of the 10 head-to-head tests while Intel wins the remaining 4. The most dramatic difference appears in the DirectX 11 test, where the AMD Radeon RX 7600S scores 140 versus the Intel Arc A770M's 69, giving AMD a 50.7% lead. That is not a small margin; it suggests a fundamental advantage in that particular API workload.

The DirectX 10 test also favors AMD heavily, with the RX 7600S posting 74 against Intel's 56, a 24.3% difference. The DirectX 9 test shows AMD ahead by 15.6%, scoring 211 versus 178. In the PassMark G3D suite, AMD wins by 23.6% (15408 versus 11774), and in GPU compute, AMD takes a 26.7% lead (6520 versus 4778). The G2D test also goes to AMD, 776 versus 711, an 8.4% margin.

Intel's wins are fewer but significant in specific areas. The most striking is the OpenCL benchmark, where the Arc A770M scores 89494 against AMD's 68012, a 31.6% advantage. The 3DMark Steel Nomad DX12 test shows Intel ahead by 20.7% (2278 versus 1888). In Vulkan, Intel wins by a narrow 0.7% (74422 versus 73868), indicating near parity in that API. The DirectX 12 PassMark test gives Intel a modest 7.7% win (70 versus 65).

Interpreting these scores requires context. The OpenCL result for Intel is unusually high relative to its other scores, suggesting the architecture excels in compute-heavy workloads that leverage OpenCL's flexibility. The DirectX 11 result for AMD is equally striking in the opposite direction, showing a legacy API where the RDNA 3.0 design has a clear edge. The overall pattern is that AMD dominates in the older DirectX APIs and general 3D rendering (G3D), while Intel pulls ahead in modern compute APIs like OpenCL and in the Steel Nomad DX12 test.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc A770M uses the DG2-512 chip based on Xe-HPG architecture, belonging to the Alchemist generation (Arc 7 Mobile). The AMD Radeon RX 7600S uses the Navi 33 chip based on RDNA 3.0, part of the Navi Mobile (RX 7000M) generation, with the codename "Hotpink Bonefish." Both are manufactured on a 6 nm process at TSMC, but their physical characteristics diverge sharply.

Intel's DG2-512 is a large die at 406 mm² with 21,700 million transistors, resulting in a transistor density of 53.4 million per mm². AMD's Navi 33 is considerably smaller at 204 mm² but packs 13,300 million transistors, giving it a higher density of 65.2 million per mm². This density difference suggests AMD's design is more efficient in using silicon area, while Intel's larger die allows for more raw resources.

The shading unit counts reflect this disparity. Intel has 4096 shading units, 256 texture mapping units (TMUs), and 128 render output units (ROPs). AMD has 1792 shading units, 112 TMUs, and 64 ROPs. Despite having less than half the shading units, AMD's FP32 performance is 15.77 TFLOPS versus Intel's 16.79 TFLOPS, a mere 6% difference. This indicates that AMD's RDNA 3.0 architecture extracts more per-shader performance, likely through higher clock speeds and better instruction efficiency.

Clock speeds tell part of the story. Intel's base clock is 1650 MHz with a boost of 2050 MHz. AMD's base is lower at 1500 MHz, but the boost reaches 2200 MHz, and the game clock is 1865 MHz. The higher boost clock helps AMD close the theoretical performance gap despite fewer cores. Ray tracing cores are 32 on Intel versus 28 on AMD, a modest difference. Memory configurations are starkly different: Intel offers 16 GB of GDDR6 on a 256-bit bus with 512.0 GB/s bandwidth, while AMD provides 8 GB on a 128-bit bus with 256.0 GB/s. Both use 16 Gbps effective memory speed.

Power consumption is another major divider. The Intel Arc A770M has a TDP of 120 W, whereas the AMD Radeon RX 7600S is rated at 75 W. This 45 W difference means AMD achieves comparable or better performance in several tests while drawing significantly less power, which is critical for mobile implementations. Both cards use PCIe 4.0 x16 interfaces and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card is marked as Active production status while Intel's is End-of-life.

Where Each One Wins

The benchmark data suggests distinct use cases where each GPU excels. The AMD Radeon RX 7600S is the clear winner for legacy DirectX workloads. Its DirectX 11 score is more than double Intel's, and it also wins in DirectX 9 and DirectX 10. This makes it the more compatible choice for older games or applications that rely on these APIs, which is common in many business or educational environments with mature software stacks.

For general 3D rendering, as measured by PassMark G3D, AMD holds a 23.6% advantage. This test typically reflects overall gaming and graphics performance across a range of scenarios. The RX 7600S also leads in GPU compute (26.7% in PassMark GPU Compute), which is relevant for tasks like video encoding, physics simulation, or scientific calculations that use general-purpose GPU compute.

The Intel Arc A770M wins in modern compute APIs. Its OpenCL score is 31.6% higher than AMD's, indicating strong raw compute throughput when using that API. The 3DMark Steel Nomad DX12 test, which is a modern DirectX 12 workload emphasizing ray tracing and advanced features, goes to Intel by 20.7%. This suggests Intel's architecture is better optimized for modern DX12 games. The Vulkan result is essentially a tie (0.7% difference), so neither card has a meaningful edge there.

For mobile users, the power envelope is decisive. AMD's 75 W TDP versus Intel's 120 W means the RX 7600S can be placed in thinner, lighter laptops with smaller batteries and less cooling. The performance parity in many tests, despite the 45 W difference, makes AMD the pragmatic choice for sustained gaming on battery or in thermally constrained chassis. Intel's larger memory pool (16 GB versus 8 GB) could benefit texture-heavy workloads or future games that require more VRAM, but the current benchmarks do not show a consistent advantage from that capacity.

The Verdict

The data presents a nuanced picture rather than a clear winner. The AMD Radeon RX 7600S wins more individual tests (6 out of 10) and demonstrates particular strength in legacy DirectX APIs, general 3D rendering, and compute workloads. Its 75 W TDP makes it a compelling choice for mobile devices where power efficiency is paramount. For users who play older games, use DirectX 11 applications, or prioritize battery life, the RX 7600S is the data-supported choice.

The Intel Arc A770M, despite being end-of-life, holds advantages in OpenCL compute (31.6% higher) and modern DirectX 12 workloads (20.7% higher in Steel Nomad). Its 16 GB memory capacity and 512.0 GB/s bandwidth provide headroom for demanding texture loads and high-resolution assets. The near-tie in Vulkan means either card works for Vulkan titles. However, the 120 W TDP is a significant drawback for mobile use, and its lower scores in DirectX 11 and G3D suggest it may struggle with general gaming performance.

The average benchmark scores tell a different story than the head-to-head wins. Intel's average across all tests is 18383, while AMD's is 16696, a difference of about 10% in Intel's favor. This is driven heavily by Intel's exceptional OpenCL score. Yet the PassMark G3D test, which is more representative of typical gaming, favors AMD by 23.6%. The percentile rankings are close: Intel sits at the 62nd percentile versus AMD's 60th. Both are mid-range mobile GPUs, with the AMD card being the more balanced choice for general use, while Intel offers specific compute advantages that may matter for certain professional workloads.

The specification table highlights that Intel's advantage lies in raw resource counts (shading units, memory, bandwidth), while AMD's lies in efficiency (transistor density, clock speed, power draw). The 6 nm process is shared, but the design philosophies diverge: Intel built a large, resource-rich die, while AMD optimized a smaller die with higher density and lower power consumption. This fundamental difference explains most of the benchmark behavior observed.
