AMD Radeon RX 6800S vs Intel Arc B570 Comparison

Where Each One Wins

The benchmark splits between the AMD Radeon RX 6800S and Intel Arc B570 are unusually clean, with each card taking five wins across the ten recorded tests. The AMD side dominates legacy DirectX workloads and 2D performance, while the Intel side takes modern DirectX 12, compute, and the newer 3DMark Steel Nomad test.

For users running older DirectX 9, 10, or 11 titles, the RX 6800S is the stronger choice. It beats the Arc B570 by 22% in Passmark DirectX 9 (200 vs 164), by 40% in DirectX 10 (91 vs 65), and by 17.8% in DirectX 11 (139 vs 118). These are not small margins; they represent a full generational step in legacy API performance. The RX 6800S also wins Passmark G2D (732 vs 661, a 10.7% lead), which indicates better raw 2D rasterization throughput.

The Intel Arc B570 counters in the areas that matter for modern gaming and productivity. In 3DMark Steel Nomad DX12, the Arc B570 scores 2649 against the RX 6800S's 1689, a 36.2% advantage. That is the single largest gap in either direction across all tested workloads. The Arc B570 also leads in Geekbench Vulkan by 16.1% (96844 vs 81272) and in Geekbench OpenCL by 12.3% (83514 vs 73202). For GPU compute tasks, the Arc B570 wins Passmark GPU Compute by 15.6% (7281 vs 6144). The Passmark DirectX 12 result goes to Intel as well, though by a smaller 9.7% margin (72 vs 65).

The overall average benchmark scores tell a similar story: the RX 6800S averages 24063 across all recorded tests, while the Arc B570 averages 20556. However, this aggregate number is skewed by the RX 6800S's strong legacy API results and its Passmark G3D score of 15908, which beats the Arc B570's 14195 by 12.1%. The Arc B570's percentile ranking among all GPUs is 65, versus 69 for the RX 6800S, but the modern workload results favor Intel significantly.

The Verdict

The data points to two different buyers. If your library consists primarily of older DirectX 9, 10, or 11 titles, or if you value 2D performance and the highest overall benchmark average, the AMD Radeon RX 6800S is the pick. It wins five of the ten head-to-head tests, including the three legacy DirectX APIs, and it holds a 12.1% lead in Passmark G3D, the traditional 3D gaming proxy.

If you are building for current-generation games, Vulkan titles, or compute-heavy workloads, the Intel Arc B570 is clearly better. Its 36.2% margin in 3DMark Steel Nomad DX12 is decisive, and its wins in Geekbench Vulkan, Geekbench OpenCL, and Passmark GPU Compute show a broader architectural advantage in modern APIs. The Arc B570 also comes with 10 GB of memory versus 8 GB, a larger bus width, and a newer process node.

The RX 6800S is an end-of-life mobile part from the Radeon RX 6000 series, released in January 2022. The Arc B570 is an active desktop product from Intel's Battlemage generation, released in January 2025. For a new build today, the Arc B570's modern API performance and active production status make it the more future-proof option. The RX 6800S remains relevant only for those specifically targeting legacy software compatibility, where its DirectX 9, 10, and 11 wins are meaningful.

One important caveat: the RX 6800S is an integrated graphics package (IGP) with no power connectors and a 100 W TDP, while the Arc B570 is a dual-slot add-in card with a 150 W TDP and a single 8-pin connector. These are different physical products for different systems, even though they compete in the same performance class.

Head-to-Head Benchmarks

The largest single win belongs to the Intel Arc B570 in 3DMark Steel Nomad DX12, where it scores 2649 against 1689 for the RX 6800S, a delta of -36.2% from AMD's perspective. This is the modern DirectX 12 flagship test, and the margin is substantial enough to call it a generational difference. The Arc B570's Geekbench Vulkan score of 96844 versus 81272 (-16.1%) reinforces that Intel's Xe2-HPG architecture handles modern low-level APIs significantly better than AMD's RDNA 2.0.

The AMD counterattack comes in Passmark DirectX 10, where the RX 6800S scores 91 against 65, a 40% lead. That is the largest win for either side in percentage terms. The RX 6800S also wins Passmark DirectX 9 by 22% (200 vs 164) and Passmark DirectX 11 by 17.8% (139 vs 118). These three legacy API results show that RDNA 2.0 retains strong driver optimization for older rendering paths.

In Passmark G3D, the RX 6800S wins 15908 vs 14195, a 12.1% margin. This is notable because G3D is a composite gaming score that blends multiple DirectX versions, so the RX 6800S's legacy API strength carries it to an overall gaming win despite losing the modern tests. The Passmark G2D result also goes to AMD, 732 vs 661, a 10.7% lead.

The Intel side wins Passmark DirectX 12 by 9.7% (72 vs 65), Passmark GPU Compute by 15.6% (7281 vs 6144), Geekbench OpenCL by 12.3% (83514 vs 73202), and Geekbench Vulkan by 16.1% as noted. The Passmark DirectX 12 margin is the smallest Intel win, suggesting that even in the newer API, the RX 6800S is not far behind in this particular benchmark, while the compute and Vulkan tests show clearer Intel advantages.

Architecture Differences

The two GPUs come from different architectural generations. The AMD Radeon RX 6800S uses the Navi 23 chip built on RDNA 2.0, manufactured by TSMC on a 7 nm process. It packs 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million per square millimeter. The Intel Arc B570 uses the BMG-G21 chip on the Xe2-HPG architecture, manufactured by TSMC on a 5 nm process. It contains 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per square millimeter. The smaller process node and higher density give Intel a clear manufacturing advantage, which translates into higher clock speeds and better compute throughput.

The RX 6800S has 2048 shading units, 128 texture mapping units, and 64 raster operation units. It also features 32 ray tracing cores, though the RDNA 2.0 ray tracing implementation is from an older generation. The Arc B570 has 2304 shading units, 144 TMUs, and 80 ROPs, but only 18 ray tracing cores. Despite fewer RT cores, the Intel architecture's newer design and higher clocks compensate in modern API tests. Neither card has dedicated tensor cores; both rely on shader-based compute for AI workloads.

Memory architecture differs substantially. The RX 6800S uses 8 GB of GDDR6 on a 128-bit bus, providing 256.0 GB/s of bandwidth. The Arc B570 uses 10 GB of GDDR6 on a 160-bit bus, providing 380.0 GB/s, a 48% bandwidth advantage. This explains part of the Arc B570's lead in compute and Vulkan workloads, which are often bandwidth-limited. Pixel and texture rates also favor Intel: the Arc B570 delivers 200.0 GPixel/s and 360.0 GTexel/s, versus 134.4 GPixel/s and 268.8 GTexel/s for the RX 6800S. FP32 compute is 11.52 TFLOPS for Intel versus 8.602 TFLOPS for AMD, and FP16 is 23.04 TFLOPS versus 17.20 TFLOPS, both at 2:1 ratios.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are equivalent. The PCIe interface is identical: PCIe 4.0 x8 for both.
