AMD Radeon RX 6800 XT vs Intel Arc A530M Comparison

AMD Radeon RX 6800 XT and Intel Arc A530M are not in the same performance class, and the data makes that clear immediately. The RX 6800 XT is a high-end desktop GPU, while the Arc A530M is a mobile part with a 65 W TDP. If you are choosing between these two, the decision is simple: the AMD card wins every benchmark where both are tested, and the only reason to consider the Intel part is if the system form factor or power envelope forces it. The RX 6800 XT delivers over 200% higher scores in both shared tests, making it the obvious pick for any desktop build where space and power are available.

The Verdict

The RX 6800 XT is the performance leader by a wide margin. In the two head-to-head benchmarks available, it beats the Arc A530M by 244.4% in Geekbench OpenCL and 214.7% in Geekbench Vulkan. Those are not close calls; they are category-level differences. The AMD card’s average benchmark score is 48,477, while the Intel part averages 46,614, but that aggregate figure masks the real story because the Intel GPU only has two benchmark results listed, both of which are dramatically lower than the AMD’s corresponding scores.

The Arc A530M is not a competitor for the RX 6800 XT in raw performance. Its 65 W TDP and IGP slot width indicate it is built for thin-and-light laptops, not high-refresh desktop gaming. The data shows the RX 6800 XT at 85th percentile among all GPUs, and the Arc A530M also sits at the 85th percentile, but that percentile ranking is misleading in this comparison because the Intel part’s nearest rivals are all mobile or workstation cards like the AMD Radeon RX 5600M and NVIDIA RTX A2000, while the AMD card’s rivals include the NVIDIA GeForce RTX 5070 Ti. The RX 6800 XT is the choice for anyone who needs maximum frame rates or compute throughput. The Arc A530M is only viable if you are constrained to a portable device, as its display outputs are listed as "Portable Device Dependent."

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The RX 6800 XT uses the Navi 21 chip built on RDNA 2.0 architecture, fabricated on a 7 nm process at TSMC with 26,800 million transistors on a 520 mm² die. The Arc A530M uses the DG2-256 chip with Xe-HPG architecture, built on a 6 nm process at TSMC with 11,500 million transistors on a 269 mm² die. The AMD chip has a transistor density of 51.5 million per mm², while Intel’s is 42.8 million per mm².

Clock speeds differ massively. The RX 6800 XT has a base clock of 1825 MHz and a boost clock of 2250 MHz, with a game clock of 2015 MHz. The Arc A530M runs at 900 MHz base and 1300 MHz boost, with no game clock listed. Memory clocks also favor AMD: 2000 MHz (16 Gbps effective) versus Intel’s 1750 MHz (14 Gbps effective). The AMD card has 72 ray tracing cores, while the Intel part has 12. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, but the RX 6800 XT is listed as end-of-life production status, while the Arc A530M is active. The AMD card uses a PCIe 4.0 x16 interface; the Intel part uses PCIe 4.0 x8.

Head-to-Head Benchmarks

The only two directly comparable benchmarks are Geekbench OpenCL and Geekbench Vulkan. In OpenCL, the RX 6800 XT scores 171,304, while the Arc A530M scores 49,735. That is a 244.4% advantage for AMD. In Vulkan, the AMD card scores 136,875 versus Intel’s 43,492, a 214.7% lead. The RX 6800 XT wins both tests, giving it a 2-0 record in head-to-head matchups.

Looking at the broader benchmark suite, the RX 6800 XT has results across eleven tests, including 3DMark Steel Nomad DX12 (3,689), Geekbench Metal (181,337), Passmark G3D (24,980), and Passmark GPU Compute (13,245). The Arc A530M only has the two Geekbench results listed, so there is no way to compare its performance in DirectX or compute workloads beyond those two. The average benchmark score for the RX 6800 XT is 48,477, which places it 1.5% ahead of the NVIDIA RTX A1000 Mobile and 3% behind the AMD Radeon RX Vega 64. The Arc A530M’s average of 46,614 puts it essentially tied with the AMD Radeon RX 5600M (0% delta) and 1.2% ahead of the NVIDIA RTX A2000. These rival comparisons show that the RX 6800 XT competes with desktop-class cards like the RTX 5070 Ti, while the Arc A530M competes with lower-tier mobile parts.

FAQ

Q: Which GPU has higher memory bandwidth?

A: The AMD Radeon RX 6800 XT has 512.0 GB/s bandwidth from its 16 GB GDDR6 memory on a 256-bit bus. The Intel Arc A530M has 224.0 GB/s from 8 GB GDDR6 on a 128-bit bus.

Q: How do the power requirements compare?

A: The RX 6800 XT has a 300 W TDP and requires a 700 W suggested PSU with two 8-pin power connectors. The Arc A530M has a 65 W TDP, no dedicated power connectors listed, and no suggested PSU, as it is an IGP-class mobile part.

Q: Do both support the same graphics APIs?

A: Yes, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Q: What is the form factor difference?

A: The RX 6800 XT is a dual-slot card measuring 267 mm in length, 120 mm in height, and 50 mm in width. The Arc A530M has no listed dimensions and is marked as "IGP" slot width, meaning it is integrated into a portable device.

Q: Which GPU has more shading units?

A: The Arc A530M has no launch MSRP listed. The RX 6800 XT has a launch MSRP of 649 USD.

Where Each One Wins

The RX 6800 XT wins in every measurable category. It has higher pixel rate (288.0 GPixel/s versus 62.40 GPixel/s), higher texture rate (648.0 GTexel/s versus 124.8 GTexel/s), and higher FP32 compute (20.74 TFLOPS versus 3.994 TFLOPS). Its FP16 performance is 41.47 TFLOPS versus Intel’s 7.987 TFLOPS. For gaming, the AMD card’s 16 GB memory and 512.0 GB/s bandwidth make it suitable for high-resolution textures and heavy asset streaming, while the Intel part’s 8 GB and 224.0 GB/s will bottleneck in those scenarios.

The Arc A530M wins only in practical deployment terms. Its 65 W TDP means it can be placed in a laptop or compact portable device, as evidenced by its "Portable Device Dependent" display outputs and lack of physical dimensions. It is an active production part with no power connector requirements, making it a drop-in solution for mobile engineering samples. The RX 6800 XT, by contrast, is end-of-life and requires a full desktop power supply and physical space for a 267 mm dual-slot card.

For compute workloads, the RX 6800 XT’s Geekbench OpenCL score of 171,304 versus 49,735 shows a 244.4% advantage in general-purpose GPU compute. In Vulkan gaming or rendering workloads, the AMD card leads by 214.7%. The only scenario where the Intel part makes sense is if you need any GPU acceleration in a device that cannot physically accommodate a discrete desktop card — there is no performance scenario where the Arc A530M wins.
