AMD Radeon 860M vs Intel Arc A530M Comparison

AMD Radeon 860M and Intel Arc A530M occupy different tiers of the mobile graphics landscape, as the recorded benchmark data shows a clear performance hierarchy between them. The Radeon 860M, an integrated part from AMD’s Krackan Point chip, delivers scores that place it near the middle of the database’s GPU distribution, while the Arc A530M, a discrete Alchemist-based mobile part, sits notably higher. The following analysis breaks down the head-to-head results, architectural distinctions, and practical implications drawn solely from the provided measurements.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these GPUs, and in both instances the Intel Arc A530M emerges as the decisive winner. In the Geekbench OpenCL test, the Arc A530M scores 49,735 against the Radeon 860M’s 22,759, a delta of -54.2% for the AMD part. This is not a marginal gap; the Intel GPU more than doubles the AMD integrated solution’s output in this compute-oriented workload. The OpenCL result aligns with the broader average benchmark scores, where the Arc A530M records 46,614 versus the Radeon 860M’s 26,401, a difference of roughly 76.6% in favor of Intel.

The Vulkan test narrows the margin somewhat but still favors the Arc A530M decisively. Here, the Intel part scores 43,492 while the Radeon 860M achieves 30,043, a delta of -30.9% for AMD. This indicates that in graphics API workloads, the Radeon 860M is comparatively stronger relative to its own OpenCL performance, but it still trails the Arc A530M by a substantial margin. The head-to-head win count is 2 for Intel and 0 for AMD, confirming that no recorded test favors the Radeon 860M.

Looking at the percentile rankings, the Arc A530M sits at the 85th percentile among all GPUs in the database, while the Radeon 860M rests at the 72nd percentile. The Arc A530M’s nearest rivals, such as the AMD Radeon RX 5600M (46,601 average score, 0% delta) and the AMD Radeon RX 6550M (46,702, -0.2%), show that Intel’s part is essentially on par with those established discrete mobile GPUs. The Radeon 860M, by contrast, competes with parts like the NVIDIA GeForce MX550 (26,421, -0.1%) and the NVIDIA GeForce RTX 5060 (26,331, +0.3%), indicating that it trades blows with entry-level discrete solutions rather than mid-range ones.

Where Each One Wins

The Radeon 860M does not win any benchmark in the recorded head-to-head data, so its advantages are structural rather than performance-based. Its 15 W TDP is dramatically lower than the Arc A530M’s 65 W, which means it consumes a fraction of the power budget. The Radeon 860M is also an IGP integrated into the Krackan Point chip, requiring no separate memory and using system shared memory, which simplifies system design and reduces component count. For thin-and-light portable devices where power draw and thermal output are primary constraints, the Radeon 860M’s low-power integrated nature is a clear fit. Its base clock of 600 MHz and boost of 3000 MHz show that it can scale up significantly under load, but the thermal ceiling of a 15 W part will limit sustained performance.

The Arc A530M wins in every measurable performance category. Its OpenCL score of 49,735 is 118.5% higher than the Radeon 860M’s 22,759, and its Vulkan score of 43,492 is 44.8% higher than the AMD part’s 30,043. The Intel GPU also offers dedicated memory: 8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth, compared to the Radeon 860M’s system shared memory with bandwidth described as system dependent. For workloads that stress memory bandwidth, such as high-resolution textures or compute tasks with large datasets, the Arc A530M’s dedicated GDDR6 provides a substantial advantage. Its pixel rate of 62.40 GPixel/s and texture rate of 124.8 GTexel/s both exceed the Radeon 860M’s 48.00 GPixel/s and 96.00 GTexel/s, respectively.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The AMD Radeon 860M uses the RDNA 3.5 architecture on a 4 nm TSMC process, manufactured as part of the Krackan Point chip. It belongs to the Navi III IGP generation for Strix Point Mobile. The Intel Arc A530M uses the Xe-HPG architecture on a 6 nm TSMC process, built on the DG2-256 chip and belonging to the Alchemist generation for Arc 5 Mobile. The process node difference is notable: 4 nm versus 6 nm, giving AMD a density advantage, although Intel’s discrete design integrates significantly more hardware.

The Arc A530M has 1,536 shading units, 96 texture mapping units, 48 ROPs, and 12 ray tracing cores. The Radeon 860M has 512 shading units, 32 TMUs, 16 ROPs, and 8 ray tracing cores. This means Intel’s part has exactly three times the shading units, three times the TMUs, and three times the ROPs of the AMD IGP. The ray tracing core count is 12 versus 8, a 50% advantage for Intel. The Intel chip also contains 11,500 million transistors on a 269 mm² die, with a transistor density of 42.8M per mm². The Radeon 860M’s transistor count and die size are listed as unknown, so no direct comparison is possible on those metrics.

Clock speeds tell a different story. The Radeon 860M boosts to 3000 MHz, while the Arc A530M boosts to only 1300 MHz. The AMD part’s higher clock partially compensates for its lower core count, but not enough to close the performance gap. The fp32 throughput is 3.072 TFLOPS for the Radeon 860M versus 3.994 TFLOPS for the Arc A530M, a 30% advantage for Intel. In fp16, the gap widens dramatically: the Radeon 860M delivers 3.072 TFLOPS (1:1 ratio) while the Arc A530M delivers 7.987 TFLOPS (2:1 ratio), meaning Intel’s part is 160% faster in half-precision compute. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are identical.

The Verdict

The data supports a clear split based on system requirements and workload priorities. The Intel Arc A530M is the superior performer in every recorded benchmark, with an average score 76.6% higher than the Radeon 860M. Its nearest rivals include the AMD Radeon RX 5600M and RX 6550M, both of which score within 0.2% of the Intel part, placing it firmly in the mid-range discrete mobile GPU tier. Systems requiring dedicated graphics memory, high texture throughput, or substantial compute performance should select the Arc A530M. Its 8 GB GDDR6 allocation and 224.0 GB/s bandwidth make it suitable for memory-intensive applications, and its 12 ray tracing cores provide more hardware support for ray-traced workloads than the AMD IGP’s 8.

The AMD Radeon 860M, conversely, fits a different role. Its 15 W TDP is 50 W lower than the Arc A530M’s 65 W, making it appropriate for ultra-portable devices where battery life and thermal management take precedence over raw graphics output. Its 3.072 TFLOPS of fp32 performance and 3000 MHz boost clock are respectable for an integrated solution, and its nearest rivals include the NVIDIA GeForce MX550 and RTX 5060, indicating it competes with entry-level discrete GPUs. The Radeon 860M’s system shared memory eliminates the cost and space of discrete VRAM, and its 4 nm process node gives it a manufacturing advantage over the 6 nm Intel part. For users who prioritize power efficiency and do not require the performance headroom of a discrete GPU, the Radeon 860M is the logical choice. For users who need the highest recorded frame rates and compute throughput, the Arc A530M is unambiguously the stronger option based on the benchmark data.
