AMD Radeon RX 9070 vs Intel Arc A750 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall win for the AMD Radeon RX 9070, which takes 9 of the 10 head-to-head benchmarks. The most dramatic separation appears in compute-heavy and legacy DirectX workloads. In PassMark GPU Compute, the RX 9070 scores 14737 against the Arc A750's 5368, a 174.5% advantage. Similarly, PassMark DirectX 11 shows a 290.3% gap, with scores of 281 and 72 respectively. These aren't marginal differences; they represent fundamentally different levels of raw throughput in shader and compute-bound tasks.

The 3DMark Steel Nomad DX12 test, which is a modern gaming-centric workload, also heavily favors the AMD card. The RX 9070 posts 6290 points versus 2612 for the Intel, a 140.8% lead. This result aligns with the PassMark G3D score, where AMD wins 25381 to 12534, a 102.5% difference. For any builder focused on contemporary game performance, this benchmark cluster indicates that the RX 9070 is in a different performance tier.

The Arc A750's single victory comes in GeekBench Vulkan, where it scores 85631 against the RX 9070's 58705, a 31.4% advantage. This is a notable outlier, as the same card loses in GeekBench OpenCL by 33.5% (131539 vs 98554). The Vulkan win suggests Intel's architecture handles that specific API workload more efficiently, but it does not translate into broader success in other test suites.

In legacy API tests, the RX 9070 dominates. PassMark DirectX 10 shows a 116.9% win (141 vs 65), and DirectX 9 shows an 89.5% win (343 vs 181). Even DirectX 12, where the gap is smallest, still goes to AMD at 74 versus 70, a 5.7% margin. The 2D performance test also favors AMD, with 1280 points against 732, a 74.9% difference. Overall, the average benchmark score for the RX 9070 is 23877, placing it in the 69th percentile of all GPUs, while the Arc A750 averages 20582 and sits in the 66th percentile.

The Verdict

The data points to a clear choice for most users: the AMD Radeon RX 9070 is the stronger card across nearly every measured workload. Its wins in 3DMark Steel Nomad, PassMark G3D, and GPU Compute indicate superior gaming and compute performance. The only scenario where the Intel Arc A750 is preferable is if the workload is specifically optimized for Vulkan, where it shows a 31.4% advantage. For a builder prioritizing general gaming, modern DirectX 12 titles, or any form of GPU compute, the RX 9070 is the logical pick. The Arc A750 is a capable card for its segment, but the benchmark data shows it lagging by over 100% in multiple core tests, which is a gap that no single API win can overcome.

Architecture Differences

The two cards come from different architectural generations and manufacturing approaches. The AMD Radeon RX 9070 uses the Navi 48 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. It packs 53,900 million transistors on a 357 mm² die, resulting in a transistor density of 151.0M per mm². The Intel Arc A750 uses the DG2-512 chip with Xe-HPG architecture, part of the Alchemist generation. It is built on a 6 nm process, also at TSMC, with 21,700 million transistors spread across a larger 406 mm² die, giving a much lower density of 53.4M per mm².

Both cards share the same shading unit count at 3584 and the same TMU count at 224. However, the RX 9070 has 128 ROPs versus 112 on the Arc A750, and it features 56 ray tracing cores compared to 28 on the Intel card. The AMD card also has a higher boost clock at 2520 MHz versus 2400 MHz, and a base clock of 1330 MHz versus 2050 MHz. The RX 9070's FP32 throughput is 36.13 TFLOPS, exactly double the Arc A750's 17.20 TFLOPS. In FP16, the RX 9070 maintains 36.13 TFLOPS at a 1:1 ratio, while the Intel card reaches 34.41 TFLOPS at a 2:1 ratio.

Memory configurations differ substantially. The RX 9070 comes with 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The Arc A750 has 8 GB of GDDR6 on the same 256-bit bus, but bandwidth drops to 512.0 GB/s. The AMD card uses PCIe 5.0 x16, while the Intel card uses PCIe 4.0 x16. Power consumption is similar, with the RX 9070 rated at 220 W TDP and the Arc A750 at 225 W TDP, both requiring a 550 W suggested PSU. The AMD card uses 2x 8-pin connectors, while the Intel uses 1x 6-pin plus 1x 8-pin.

Where Each One Wins

The AMD Radeon RX 9070 is the winner for almost every use case derived from the benchmark data. It leads in modern gaming workloads, as shown by the 3DMark Steel Nomad DX12 score, and in general 3D rendering via PassMark G3D. Its compute performance is dramatically higher, evidenced by the 174.5% lead in PassMark GPU Compute, making it the better choice for tasks like rendering, physics simulation, or any GPU-accelerated compute. It also handles legacy DirectX APIs far better, with wins in DirectX 9, 10, and 11 ranging from 89.5% to 290.3%. For 2D desktop work, the PassMark G2D score of 1280 versus 732 indicates smoother interface rendering.

The Intel Arc A750 wins only in the GeekBench Vulkan test. This makes it the preferred option specifically for applications that rely heavily on the Vulkan API. If a user has a workload that is known to be Vulkan-optimized, such as certain emulators or specific game engines, the Arc A750's 31.4% advantage in that single test could be meaningful. However, this is a narrow niche. The data does not support recommending the Arc A750 for general gaming, compute, or legacy API compatibility.
