Intel Arc A530M vs NVIDIA GeForce RTX 5080 Comparison

The Verdict

The benchmark database positions these two GPUs at opposite ends of the performance spectrum. The NVIDIA GeForce RTX 5080 is a desktop flagship-class part with an average benchmark score of 56,083, placing it in the 87th percentile of all GPUs. The Intel Arc A530M is a mobile integrated graphics processor with an average score of 46,614, sitting in the 85th percentile. The data shows a clear performance hierarchy: the RTX 5080 leads by roughly 20% in average score, and the head-to-head results show a far wider gap in compute workloads. The RTX 5080 wins both recorded head-to-head tests decisively, with a 374.3% lead in Geekbench OpenCL and a 487.3% lead in Geekbench Vulkan. The Intel Arc A530M, while competitive within its own mobile segment, is not a direct alternative to the RTX 5080. Buyers seeking maximum desktop performance should choose the RTX 5080; the Arc A530M is suited only for portable systems where power constraints dominate.

Architecture Differences

The two GPUs are built on fundamentally different architectures and process nodes. The RTX 5080 uses NVIDIA's Blackwell 2.0 architecture on a 5 nm TSMC process, with a GB203 chip comprising 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per mm². The Arc A530M uses Intel's Xe-HPG architecture (Alchemist generation) on a 6 nm TSMC process, with a DG2-256 chip containing 11,500 million transistors on a 269 mm² die, giving a transistor density of 42.8 million per mm². This means the RTX 5080 packs roughly four times the transistor count into a larger die, with nearly three times the density.

Core configurations differ substantially. The RTX 5080 has 10,752 shading units, 336 texture mapping units, 112 ROPs, 84 ray tracing cores, and 336 tensor cores. The Arc A530M has 1,536 shading units, 96 TMUs, 48 ROPs, and 12 ray tracing cores, with no tensor cores listed. The RTX 5080's FP32 throughput is 56.28 TFLOPS, while the Arc A530M manages 3.994 TFLOPS FP32; the Arc does double FP16 throughput at 7.987 TFLOPS (2:1 ratio) versus the RTX 5080's 56.28 TFLOPS FP16 (1:1 ratio).

Memory systems are equally divergent. The RTX 5080 uses 16 GB of GDDR7 on a 256-bit bus with 960.0 GB/s bandwidth, clocked at 1875 MHz (30 Gbps effective). The Arc A530M has 8 GB of GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth, clocked at 1750 MHz (14 Gbps effective). The RTX 5080's memory bandwidth is over four times higher, which directly impacts high-resolution texture streaming and compute workloads.

Power and form factor differences are stark. The RTX 5080 has a 360 W TDP, is dual-slot, uses a single 16-pin power connector, and requires a 750 W suggested PSU. The Arc A530M has a 65 W TDP and is listed as an IGP (integrated graphics processor) with portable device-dependent display outputs. The RTX 5080 connects via PCIe 5.0 x16, while the Arc A530M uses PCIe 4.0 x8. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 was released on January 29, 2025, and the Arc A530M on July 31, 2023. The RTX 5080 has a launch MSRP of 999 USD.

Where Each One Wins

The benchmark results indicate a complete dominance by the RTX 5080 in the two recorded head-to-head tests, but the use-case split goes beyond raw scores. For desktop gaming and workstation tasks, the RTX 5080 is the clear choice: its 56.28 TFLOPS FP32 compute, 960.0 GB/s memory bandwidth, and 16 GB VRAM make it suitable for 4K gaming, ray-traced workloads, and large model inference. Its 293.1 GPixel/s pixel rate and 879.3 GTexel/s texture rate further support high-resolution rendering.

The Arc A530M, with its 65 W TDP, is designed for thin-and-light laptops where power draw is the primary constraint. Its 62.40 GPixel/s pixel rate and 124.8 GTexel/s texture rate are a fraction of the RTX 5080's, but the integrated form factor allows deployment in portable devices. The Arc A530M's 8 GB VRAM is sufficient for 1080p gaming at moderate settings, and its 7.987 TFLOPS FP16 throughput (2:1 ratio) suggests some compute utility for AI-adjacent tasks, though it lacks dedicated tensor cores. The RTX 5080's 336 tensor cores give it a decisive advantage in machine learning workloads, though specific tensor performance numbers are not recorded in the database.

The RTX 5080 also wins on connectivity: it offers 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs, while the Arc A530M's outputs are portable device dependent. For users needing multi-monitor setups or high refresh rate external displays, the RTX 5080 is the only option with fixed, high-bandwidth outputs.

Head-to-Head Benchmarks

The database records two head-to-head benchmark comparisons between these GPUs, both in compute-oriented tests. The results are lopsided. In Geekbench OpenCL, the RTX 5080 scores 235,901 against the Arc A530M's 49,735, a delta of 374.3%. This is not a marginal difference: the RTX 5080 achieves nearly five times the raw compute throughput. The OpenCL test stresses general-purpose GPU compute, and the RTX 5080's 10,752 shading units and 56.28 TFLOPS FP32 performance dominate the Arc A530M's 1,536 shading units and 3.994 TFLOPS.

The Geekbench Vulkan test shows an even wider gap. The RTX 5080 scores 255,450 versus 43,492 for the Arc A530M, a delta of 487.3%. Vulkan is a low-level graphics and compute API, and the RTX 5080's higher texture rate (879.3 GTexel/s versus 124.8 GTexel/s) and pixel rate (293.1 GPixel/s versus 62.40 GPixel/s) contribute to this result. The RTX 5080's 16 GB GDDR7 memory with 960.0 GB/s bandwidth also provides a substantial advantage over the Arc A530M's 8 GB GDDR6 at 224.0 GB/s, particularly in memory-bound Vulkan workloads.

The RTX 5080 wins both head-to-head tests, giving it a 2-0 record. The Arc A530M has zero wins. The nearest rivals data contextualizes these results. The RTX 5080's closest competitor is the AMD Radeon RX 9070 GRE at 57,367 average score, which is 2.2% higher, meaning the RTX 5080 slightly trails the top of its immediate competitive set. The Arc A530M's nearest rival is the AMD Radeon RX 6550M at 46,702, which is 0.2% higher, indicating the Arc A530M sits at parity with its direct mobile competitors. The RTX 5080's other rivals include the AMD Radeon 8060S (0.6% higher), the AMD Radeon RX 6750 GRE 12 GB (0.7% higher), and the AMD Radeon Pro W5700X (2.3% higher). The Arc A530M's rivals include the AMD Radeon RX 5600M (0% delta), the NVIDIA RTX A2000 (1.2% higher), and the NVIDIA RTX 5880 Ada Generation (1.4% higher).

The data shows that while the RTX 5080 is near the top of its desktop class, it is not the absolute leader, as the RX 9070 GRE edges it out by 2.2%. The Arc A530M, conversely, is essentially tied with the RX 6550M and RX 5600M, and slightly ahead of the RTX A2000 and RTX 5880 Ada Generation. Neither GPU dominates its segment, but the RTX 5080 occupies a far higher absolute performance tier. The Arc A530M's 85th percentile ranking despite a much lower average score suggests that the mobile GPU pool skews toward lower-performing parts, whereas the RTX 5080's 87th percentile reflects a more competitive desktop field. The massive deltas in the head-to-head tests, 374.3% and 487.3%, are the strongest signal in the data: these are not comparable products, and any workload that runs on both will see a multi-fold performance difference in favor of the RTX 5080.
