AMD Radeon RX 6600 XT vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between these two GPUs, with each dominating in different benchmark categories. The AMD Radeon RX 6600 XT wins 6 of the 10 head-to-head tests, while the Intel Arc B570 wins 4. However, the magnitude of the wins matters as much as the count.

The most decisive result is in 3DMark Steel Nomad DX12, where the Intel Arc B570 scores 2649 versus the AMD Radeon RX 6600 XT's 1804. That is a 31.9% advantage for Intel, the largest delta in either direction across all tests. This is a modern DirectX 12 workload, and the gap is substantial. The Arc B570 also wins the Geekbench Vulkan test by a wide margin, scoring 96844 against 72417, a 25.2% lead. In Geekbench OpenCL, the Intel card again comes out ahead, 83514 versus 80503, though the margin is a smaller 3.6%. The final Intel win is in Passmark DirectX 12, where the B570 scores 72 versus 61, a 15.3% advantage.

The AMD Radeon RX 6600 XT, for its part, counters with wins in several legacy and compute-oriented benchmarks. The largest single delta is in Passmark DirectX 10, where the AMD card scores 109 against Intel's 65, a 67.7% lead. That is the most lopsided result in the entire comparison. In Passmark DirectX 11, the RX 6600 XT scores 163 versus 118, a 38.1% advantage. The AMD card also leads in Passmark DirectX 9, scoring 194 against 164, an 18.3% gap. In Passmark G2D, the AMD card scores 912 versus 661, a 38% lead. The Passmark G3D test favors the RX 6600 XT as well, 16461 versus 14195, a 16% difference. Finally, in Passmark GPU Compute, the AMD card edges out Intel, 7520 versus 7281, a modest 3.3% margin.

The overall average benchmark scores reflect this split. The AMD Radeon RX 6600 XT has an average benchmark score of 24442, while the Intel Arc B570 sits at 20556. That puts the AMD card 18.9% higher on average, even though the Intel card wins the most modern workload. The percentile rankings also differ, with the RX 6600 XT at the 70th percentile of all GPUs and the Arc B570 at the 65th.

Where Each One Wins

Looking at the wins by workload type, the Intel Arc B570 is clearly the stronger choice for modern DirectX 12 and Vulkan applications. The 3DMark Steel Nomad DX12 result is the standout, with the B570 delivering a 31.9% performance advantage over the RX 6600 XT. For gamers or professionals running current-generation engines that use these APIs, the data points firmly toward Intel. The Vulkan score reinforces this, with a 25.2% lead. The OpenCL result is less decisive, but still favors Intel by 3.6%, suggesting the B570 holds an edge in general compute workloads that leverage this API.

The AMD Radeon RX 6600 XT is the better performer in older DirectX versions and in 2D-oriented tasks. The 67.7% lead in DirectX 10 is massive, and the 38.1% lead in DirectX 11 is also significant. For DirectX 9, the RX 6600 XT maintains an 18.3% advantage. These results indicate that the AMD architecture handles legacy API paths with far greater efficiency. The Passmark G2D score, which measures 2D graphics performance, also goes to AMD by 38%, which could matter for desktop workloads or applications with heavy 2D rendering. The Passmark G3D score, which is a broader 3D gaming metric, favors AMD by 16%, indicating that in mixed DirectX version gaming scenarios, the RX 6600 XT holds a lead. The GPU Compute result is close, but AMD still wins by 3.3%.

Architecture Differences

The two GPUs are built on different architectures and process nodes, which explains their divergent benchmark profiles. The AMD Radeon RX 6600 XT uses the Navi 23 chip based on RDNA 2.0 architecture, manufactured on a 7 nm process at TSMC. The Intel Arc B570 uses the BMG-G21 chip based on Xe2-HPG architecture, manufactured on a 5 nm process, also at TSMC. The process node difference is significant, with Intel using a smaller transistor geometry.

Transistor counts differ substantially. The Intel chip packs 19,600 million transistors, while the AMD chip has 11,060 million. The die size also differs, with Intel at 272 mm² and AMD at 237 mm². This gives the Intel chip a higher transistor density of 72.1 million per mm², compared to AMD's 46.7 million per mm².

The memory subsystems are notably different. The Intel Arc B570 comes with 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The AMD Radeon RX 6600 XT has 8 GB of GDDR6 memory on a 128-bit bus, with 256.0 GB/s of bandwidth. This gives Intel a 48.4% bandwidth advantage, which likely contributes to its strong performance in memory-heavy modern workloads.

Core counts also differ. The Intel card has 2304 shading units, 144 texture mapping units, and 80 render output units. The AMD card has 2048 shading units, 128 TMUs, and 64 ROPs. Intel also has 18 ray tracing cores, while AMD has 32. The pixel rate for Intel is 200.0 GPixel/s versus AMD's 165.7 GPixel/s, and the texture rate is 360.0 GTexel/s versus 331.4 GTexel/s. In raw FP32 compute, Intel scores 11.52 TFLOPS against AMD's 10.60 TFLOPS.

Clock speeds show different strategies. The AMD card has a base clock of 1968 MHz and a boost clock of 2589 MHz, with a game clock of 2359 MHz. The Intel card runs at a flat 2500 MHz for both base and boost. Memory clocks also differ, with AMD at 2000 MHz (16 Gbps effective) and Intel at 2375 MHz (19 Gbps effective).

The Verdict

The data presents a clear choice based on workload priorities. For modern DirectX 12 and Vulkan applications, the Intel Arc B570 is the stronger option. Its 31.9% lead in 3DMark Steel Nomad DX12 and 25.2% lead in Geekbench Vulkan are decisive. The 10 GB memory buffer with 48.4% more bandwidth also positions it well for future titles that demand larger memory pools. The Intel card's higher FP32 compute (11.52 TFLOPS versus 10.60 TFLOPS) and higher pixel/texture rates support this direction.

For users running older DirectX versions, particularly DirectX 9, 10, and 11, the AMD Radeon RX 6600 XT is clearly superior. The 67.7% lead in DirectX 10 and 38.1% lead in DirectX 11 are substantial. The RX 6600 XT also wins the broader Passmark G3D test by 16%, suggesting that in mixed DirectX version gaming, it provides a more consistent experience. Its 2D performance is also much stronger, with a 38% lead in Passmark G2D.

The production status differs, with the AMD card listed as end-of-life and the Intel card as active. The AMD card was released on 2021-07-29, while the Intel card came out on 2025-01-15. The AMD card has a launch MSRP of 379 USD, while the Intel card has a launch MSRP of 219 USD.

The overall average benchmark score favors the AMD card, 24442 versus 20556, and the AMD card holds a higher percentile rank at 70 versus 65. However, this average is heavily weighted by the AMD card's dominance in legacy API tests. For a user focused on current-generation games and applications that use DirectX 12 or Vulkan exclusively, the Intel Arc B570 is the data-backed pick. For a user with a library of older games or applications relying on DirectX 11 or earlier, the AMD Radeon RX 6600 XT is the safer choice. The compute results are nearly tied, with AMD winning Passmark GPU Compute by just 3.3%, so that is not a differentiating factor.
