AMD Radeon RX 6750 XT vs Intel Arc B580 Comparison

Head-to-Head Benchmarks

The benchmark data tells two very different stories depending on which test suite is examined. In the 3DMark Steel Nomad DX12 test, the Intel Arc B580 posts a score of 3068, beating the AMD Radeon RX 6750 XT's 2548 by a substantial 16.9% margin. This is Intel's largest win in the entire comparison. The gap widens dramatically in the Geekbench OpenCL test, where the Arc B580 scores 92821 against a mere 16360 for the RX 6750 XT, a staggering 82.4% advantage. Even in Geekbench Vulkan, Intel holds a 10.6% lead with 109672 versus 98089. These three wins give the Arc B580 a commanding lead in modern, compute-heavy workloads.

However, the AMD card dominates across the Passmark suite. The RX 6750 XT wins seven of the ten head-to-head tests, including every DirectX variant. In Passmark DirectX 10, the AMD card scores 125 versus 76 for Intel, a 64.5% advantage. DirectX 11 shows a 40.6% lead (180 vs 128), while DirectX 9 shows a 43.7% lead (263 vs 183). The gap narrows in DirectX 12, where AMD wins by only 5.3% (80 vs 76). Beyond the API-specific tests, AMD also wins the Passmark G3D test by 31.4% (20700 vs 15748), the G2D test by 37.1% (972 vs 709), and the GPU Compute test by 23.6% (9550 vs 7729).

The overall average benchmark score places the RX 6750 XT at 26011, which is 13% higher than the Arc B580's 23021. This average, combined with the total win count (7 for AMD, 3 for Intel), suggests that while Intel excels in specific modern workloads, the AMD card maintains a broader performance advantage across the legacy and general-purpose test categories. The Geekbench OpenCL result is particularly curious: it is so lopsided that it may indicate a difference in how the two architectures handle OpenCL's scheduling rather than raw hardware capability.

Where Each One Wins

The split is clear. Intel's Arc B580 is the winner for modern, API-heavy workloads where the database shows a consistent advantage. The 3DMark Steel Nomad DX12 test, which represents a modern DirectX 12 gaming scenario, goes to Intel by 16.9%. The Geekbench Vulkan and OpenCL results suggest that Intel's Xe2-HPG architecture is better optimized for compute shaders and async execution. This makes the Arc B580 the more interesting choice for users working with Vulkan-based games, GPU compute tasks, or applications that leverage OpenCL. The 82.4% OpenCL blowout is not a marginal difference; it indicates a fundamentally different performance profile.

The AMD RX 6750 XT is the winner for legacy DirectX titles and 2D/3D rasterization workloads. The Passmark DirectX 9, 10, and 11 tests all show AMD leading by significant margins, ranging from 40.6% to 64.5%. The RX 6750 XT also wins the 3D graphics test by 31.4%, which likely reflects a more straightforward rasterization pipeline. The 37.1% lead in the 2D test is notable, suggesting better performance in desktop compositing and older GUI applications. The 23.6% win in GPU compute, while smaller, still points to AMD's RDNA 2.0 architecture handling general-purpose compute more consistently. For anyone running older games, classic DirectX applications, or software that relies on the legacy Passmark tests as a proxy, the RX 6750 XT is the more reliable performer.

Architecture Differences

The two cards represent different architectural philosophies and generations. The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture, using the Navi 22 chip manufactured on a 7 nm process by TSMC. It packs 17,200 million transistors onto a die size of 335 mm², resulting in a transistor density of 51.3 million per mm². The Intel Arc B580, on the other hand, uses the Xe2-HPG architecture, built on the BMG-G21 chip, and is manufactured on a more advanced 5 nm process, also by TSMC. Intel's chip contains 19,600 million transistors on a smaller 272 mm² die, pushing the transistor density to 72.1 million per mm². This higher density is a key differentiator, allowing Intel to fit more logic into a smaller physical space.

Both cards feature 2560 shading units and 160 texture mapping units. The similarity ends there. AMD's RX 6750 XT has 64 render output units (ROPs) and 40 ray tracing cores, while the Intel Arc B580 has 80 ROPs and only 20 ray tracing cores. This doubling of ROPs on the Intel side helps explain its better pixel rate, which is 213.6 GPixel/s versus AMD's 166.4 GPixel/s. The texture rate also favors Intel, at 427.2 GTexel/s versus 416.0 GTexel/s, a marginal but present lead. In pure compute, the Intel card also has a slight edge in FP32 (13.67 TFLOPS vs 13.31) and FP16 (27.34 vs 26.62), suggesting the Xe2-HPG architecture is more efficient at raw shader math.

Memory configuration is nearly identical: both have 12 GB of GDDR6 on a 192-bit bus. The Arc B580 has a slightly higher memory bandwidth of 456.0 GB/s compared to 432.0 GB/s for the RX 6750 XT. This is a modest bandwidth advantage for Intel, possibly contributing to its high-resolution performance in the 3DMark test. The memory clock for Intel is 2375 MHz (19 Gbps effective), while AMD's is 2250 MHz (18 Gbps effective).

The power profiles differ significantly. The AMD card is rated at 250 W and requires a 600 W power supply, with a single 6-pin and a single 8-pin connector. The Intel Arc B580 is more efficient on paper, with a 190 W TDP and a recommended 450 W PSU, needing only a single 8-pin connector. The bus interface also differs: AMD uses PCIe 4.0 x16, while Intel uses PCIe 4.0 x8, which could affect bandwidth in some motherboard configurations.

The Verdict

The data does not support a single universal winner. The AMD Radeon RX 6750 XT, with an average benchmark score of 26011, occupies the 71st percentile of all GPUs. The Intel Arc B580, averaging 23021, sits in the 68th percentile. The AMD card is clearly ahead in the aggregate, but the margin in the head-to-head is driven by its dominance in the Passmark suite. The RX 6750 XT's nearest rivals in the database are the AMD Radeon R9 M395X, FirePro W7100, and FirePro D700, all within 0.7% of its score, and the NVIDIA GeForce RTX 3080 Ti Mobile, which is 1.1% behind. This suggests the RX 6750 XT is a strong, reliable performer that sits in a well-established performance tier.

The Intel Arc B580's nearest rivals are the AMD Radeon RX 580 2048SP (0.2% behind), the NVIDIA GeForce RTX 2080 (0.6% ahead), the NVIDIA GeForce RTX 3080 (0.7% behind), and the NVIDIA P106-100 (1% behind). This is a slightly more volatile position, with the Arc B580 trading blows with older high-end cards and newer low-mid cards. The Arc B580 is the newer product, released in December 2024 with a launch MSRP of 249 USD, versus the RX 6750 XT's launch MSRP of 549 USD. However, per the rules, the focus is on performance.

For a user prioritizing modern DirectX 12 or Vulkan gaming, the Intel Arc B580 is the statistically better choice. The 16.9% lead in 3DMark Steel Nomad and the 10.6% lead in Vulkan are not small differences. For those relying on older DirectX 9/10/11 titles, the RX 6750 XT is the only rational pick, given the 40-64% advantages. The AMD card's higher average benchmark score and higher percentile rank make it the more consistent performer across the entire test suite, but the Intel card's wins are in the workloads that are most relevant to current and future gaming. The recommendation must be conditional: the AMD card for legacy and general use, the Intel card for modern API dominance.
