AMD Radeon RX 580 2048SP vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance advantage for the Intel Arc B570 across every benchmark where both cards were measured. In the 3DMark Steel Nomad DX12 test, the Arc B570 scores 2649 against the RX 580 2048SP's 849, a delta of -68% from the AMD card's perspective, meaning the Intel card is roughly 3.1 times faster in this modern DirectX 12 workload. This is not a marginal gap; it is a generational chasm.

The compute-oriented results reinforce the same story. In Geekbench OpenCL, the Arc B570 posts 83514 while the RX 580 2048SP manages 29668, a 64.5% deficit for the older AMD part. The Vulkan result is similarly lopsided: 96844 for Intel versus 38666 for AMD, a 60.1% difference. Across all three head-to-head tests, the Intel Arc B570 wins every single one.

Looking at the broader database averages, the picture gets more nuanced. The RX 580 2048SP has an average benchmark score of 23061, while the Arc B570 sits at 20556. The AMD card actually holds a higher aggregate average, which is interesting given its complete failure in the direct comparisons. This happens because the two cards are tested against different pools of benchmarks; the RX 580 2048SP's average draws from a set that flatters its older architecture, while the Arc B570's average includes more diverse workloads. The nearest rivals for each card confirm they occupy different tiers: the RX 580 2048SP sits within 0.8% of the NVIDIA RTX 3080, RTX 2080, and Intel Arc B580 in its rival set, while the Arc B570 trades places within 0.5% of the RTX 3070 Mobile, Arc A750, and older mobile parts.

The percentile rankings are telling. The RX 580 2048SP lands at the 68th percentile among all GPUs in the database, whereas the Arc B570 sits at the 65th. Despite losing every head-to-head test, the AMD card's percentile is slightly higher, again reflecting the different benchmark compositions feeding those rankings. A builder should not read too much into that: the three tests where both cards appear together are unambiguous, and the Intel part wins all of them by enormous margins.

The Verdict

The data points to a simple conclusion: the Intel Arc B570 is the faster card in every workload that the database records for both. The RX 580 2048SP's only statistical advantages are its higher aggregate average score and slightly better percentile ranking, both artifacts of different benchmark pools rather than evidence of actual performance superiority. If the choice is based purely on measured performance in shared tests, the Arc B570 wins outright.

The RX 580 2048SP is an end-of-life product from 2018, built on a 14 nm process with 5,700 million transistors. The Arc B570 is an active product from 2025, built on a 5 nm process with 19,600 million transistors. The generational gap is stark. For anyone building a new system or upgrading from a card of that era, the Arc B570 is the only rational pick based on these numbers. It delivers roughly 3.1 times the DX12 performance, 2.8 times the OpenCL performance, and 2.5 times the Vulkan performance of the RX 580 2048SP.

That said, the RX 580 2048SP is not without a constituency. Its 68th percentile ranking means it outperforms most GPUs in the database, and its nearest rivals include the RTX 3080 and RTX 2080 with deltas under 1%. For someone who already owns the AMD card and is weighing a sidegrade, the data suggests there is no reason to move to a comparable card; the Arc B570 is a genuine upgrade, not a lateral move. The verdict is clear: the Arc B570 is the superior product in every measured dimension, and the RX 580 2048SP should only be considered if it is already in hand.

Architecture Differences

The two cards come from completely different architectural eras. The AMD Radeon RX 580 2048SP uses the Polaris 20 chip, based on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. It packs 5,700 million transistors onto a 232 mm² die, yielding a transistor density of 24.6 million per square millimeter. The Intel Arc B570 uses the BMG-G21 chip, based on Xe2-HPG architecture, fabricated on a 5 nm process at TSMC. It contains 19,600 million transistors on a 272 mm² die, for a density of 72.1 million per square millimeter, nearly three times the transistor density of the AMD part.

The compute resources differ substantially. The RX 580 2048SP has 2048 shading units, 128 texture mapping units, and 32 ROPs. The Arc B570 has 2304 shading units, 144 TMUs, and 80 ROPs. The Intel card also includes 18 ray tracing cores, a feature the AMD card lacks entirely. The pixel rate tells the story: 41.09 GPixel/s for AMD versus 200.0 GPixel/s for Intel, a nearly 5x gap. Texture rate is 164.4 GTexel/s for AMD versus 360.0 GTexel/s for Intel. FP32 throughput is 5.259 TFLOPS for AMD versus 11.52 TFLOPS for Intel, more than double. The FP16 figures diverge even more: the AMD card manages 5.259 TFLOPS at a 1:1 ratio, while the Intel card reaches 23.04 TFLOPS at a 2:1 ratio.

Memory architecture is another major divergence. The RX 580 2048SP uses 4 GB of GDDR5 on a 256-bit bus, delivering 224.0 GB/s of bandwidth. The Arc B570 uses 10 GB of GDDR6 on a 160-bit bus, delivering 380.0 GB/s. Despite the narrower bus, the faster memory more than compensates. The Intel card also supports PCIe 4.0 x8, while the AMD card is limited to PCIe 3.0 x16. The API support reflects the newer architecture: the Arc B570 supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the RX 580 2048SP tops out at DirectX 12 (12_0) and Vulkan 1.3. Both support OpenGL 4.6.

Where Each One Wins

The Intel Arc B570 wins in every measured benchmark that includes both cards. Its 3DMark Steel Nomad DX12 score of 2649 crushes the RX 580 2048SP's 849, making it the clear choice for modern DirectX 12 gaming and any workload that stresses current API features. Its Geekbench OpenCL score of 83514 and Vulkan score of 96844 both dwarf the AMD card's 29668 and 38666 respectively. For compute workloads, content creation, and Vulkan-based games, the Arc B570 is the superior option. The Intel card also brings ray tracing hardware, 10 GB of memory, and nearly double the FP32 throughput, making it the pick for any task that can leverage those resources.

The RX 580 2048SP does not win any head-to-head test, but its higher average score of 23061 and 68th percentile ranking suggest it remains competitive within its own benchmark pool. Its nearest rivals include the RTX 3080 and RTX 2080, both within 0.8% of its average score. For legacy DirectX 11 or OpenGL workloads, or for anyone already running a system built around the Polaris architecture, the AMD card can still hold its own in its peer group. Its 4 GB of VRAM and 224.0 GB/s bandwidth are modest by modern standards, but for older titles and less demanding applications, it remains serviceable. The real takeaway is that the RX 580 2048SP is a card from 2018, and the Arc B570 is a card from 2025; the data reflects that gap faithfully.
