AMD Radeon RX 9070 XT vs Intel Arc Pro B390 Comparison

Where Each One Wins

The AMD Radeon RX 9070 XT and Intel Arc Pro B390 occupy entirely different segments of the graphics hardware spectrum, and the recorded benchmark data reflects that divide clearly. The RX 9070 XT is a discrete, high-throughput RDNA 4.0 card designed for sustained rendering workloads, while the Arc Pro B390 is an integrated graphics solution built into Intel's Panther Lake processors, targeting portability and efficiency rather than raw output.

Looking strictly at the database entries, the RX 9070 XT carries ten individual benchmark results across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads. The Arc Pro B390, by contrast, has no recorded benchmarks at all in the database, which means every measurable win in the head-to-head comparison goes to the AMD part. The RX 9070 XT's average benchmark score sits at 13543, while the Intel part registers an average score of zero due to the absence of test data.

The functional split is clearer when examining the hardware profiles. The RX 9070 XT delivers 4096 shading units, 256 texture mapping units, and 128 raster operation pipelines, with 64 dedicated ray tracing cores. The Arc Pro B390 provides 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. In terms of raw compute, the AMD card reaches 48.66 TFLOPS of FP32 throughput, while the Intel integrated solution manages 7.680 TFLOPS. That is a 6.3x gap in single-precision floating point performance, a decisive margin for any GPU-bound workload.

The Radeon card also wins on memory capacity and bandwidth. It carries 16 GB of GDDR6 memory across a 256-bit bus, delivering 644.6 GB/s of bandwidth. The Arc Pro B390 uses system shared memory, with bandwidth listed as system dependent, meaning it borrows from the host CPU's memory pool and is subject to platform constraints. For texture-heavy scenes, large datasets, or high-resolution rendering, the dedicated VRAM of the RX 9070 XT provides a structural advantage that shared memory cannot match.

However, the Intel part does claim wins in efficiency and integration. Its TDP is 80 W versus 304 W for the AMD card, and it requires no power connectors, drawing power directly from the host platform. The Arc Pro B390 is an IGP, meaning it occupies no expansion slot and fits into portable devices, whereas the RX 9070 XT is a dual-slot card requiring a PCIe 5.0 x16 slot and a 700 W suggested power supply. For systems where space, thermals, and power draw are the primary constraints, the Intel solution is the only viable option.

Architecture Differences

The two GPUs come from different manufacturing and design philosophies. The AMD Radeon RX 9070 XT uses the Navi 48 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. The die measures 357 mm² and contains 53,900 million transistors, yielding a transistor density of 151.0 million per square millimeter. The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel's own foundries. Its transistor count and die size are listed as unknown in the database.

Clock behavior differs substantially. The RX 9070 XT has a base clock of 1660 MHz, a game clock of 2400 MHz, and a boost clock of 2970 MHz. The Arc Pro B390 starts at a very low 300 MHz base and boosts to 2500 MHz. The AMD card's higher sustained clocks, combined with its larger execution resource pool, produce a pixel rate of 380.2 GPixel/s and a texture rate of 760.3 GTexel/s. The Intel part delivers 60.00 GPixel/s and 120.0 GTexel/s respectively.

Memory architecture is another fundamental divergence. The RX 9070 XT uses dedicated GDDR6 memory clocked at 2518 MHz with an effective data rate of 20.1 Gbps. The Arc Pro B390 has no dedicated memory of its own, relying entirely on system shared memory, with bus width and type both listed as system shared. This means the Intel integrated GPU's performance is highly dependent on the host system's memory configuration, a variable the database records as system dependent.

Feature support is similar at the API level. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9070 XT also includes hardware ray tracing through its 64 RT cores, while the Arc Pro B390 has 12 RT cores, indicating a much smaller ray tracing footprint. Neither card lists tensor cores, so AI acceleration relies on the general-purpose shading units.

The RX 9070 XT uses a PCIe 5.0 x16 interface, while the Arc Pro B390 is an IGP with no external bus interface. Display outputs for the AMD card include one HDMI 2.1b port and three DisplayPort 2.1a ports. The Intel part's display outputs are listed as portable device dependent, reflecting its integration into mobile and compact form factors.

Release timing also separates the two. The RX 9070 XT launched on March 5, 2025, with a launch MSRP of 599 USD. The Arc Pro B390 is scheduled for release on January 26, 2026, with no MSRP recorded. The AMD card's predecessor is listed as Navi III, while the Intel part's predecessor is HD Graphics-WM, indicating a generational leap from Intel's older integrated graphics line.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the RX 9070 XT and the Arc Pro B390. The wins counter shows zero for both cards, and the headToHeadBenchmarks array is empty. This is a direct consequence of the Intel part having no recorded benchmark results whatsoever. Any comparison must therefore rely on the individual benchmark scores of the AMD card and the architectural specifications of the Intel part.

The RX 9070 XT's benchmark results are as follows: 7260 in 3DMark Steel Nomad DX12, 17428 in Geekbench OpenCL, 65879 in Geekbench Vulkan, 154 in PassMark DirectX 10, 292 in PassMark DirectX 11, 78 in PassMark DirectX 12, 353 in PassMark DirectX 9, 1328 in PassMark G2D, 26795 in PassMark G3D, and 15864 in PassMark GPU Compute. Its average benchmark score is 13543, placing it in the 55th percentile among all GPUs tracked in the database.

The nearest rivals for the RX 9070 XT provide context for its positioning. The AMD Radeon HD 7770M has an average score of 13536, a 0.1% delta from the RX 9070 XT. The NVIDIA GeForce GTX 570 scores 13515, a 0.2% delta. The NVIDIA P106-090 scores 13470, a 0.5% delta. The AMD Radeon Pro 555 scores 13407, a 1% delta. These are all older or lower-tier cards, and the RX 9070 XT's average score sits essentially even with them, which is surprising given its modern architecture and high specifications.

The Arc Pro B390 has no such rival data. Its percentile is listed at 50, but with no benchmarks and no average score, that percentile is effectively a placeholder rather than a measured ranking. The absence of data means the database cannot yet position the Intel part relative to any existing GPU.

For the purposes of this comparison, the RX 9070 XT wins every benchmark category by default. Its lowest recorded score, 78 in PassMark DirectX 12, still represents a measurable result, whereas the Intel part has no results at all. The AMD card's strongest relative performance appears in Geekbench Vulkan at 65879, which is over 3.7x its OpenCL score of 17428, indicating strong Vulkan optimization. The PassMark G3D score of 26795 versus the G2D score of 1328 shows the card is heavily skewed toward 3D workloads, as expected for a discrete gaming and rendering GPU.

The Verdict

The data points to a straightforward conclusion: the AMD Radeon RX 9070 XT is the only choice for any workload requiring significant graphics compute. It has ten recorded benchmark scores, a measurable average of 13543, and a 55th percentile ranking among all GPUs. The Intel Arc Pro B390 has zero benchmarks, zero average score, and no rival data, making it impossible to recommend for any performance-sensitive task based on the database.

The RX 9070 XT delivers 48.66 TFLOPS of FP32 compute, 644.6 GB/s of dedicated memory bandwidth, and 16 GB of GDDR6 VRAM. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, and it has 64 ray tracing cores. For gaming, 3D rendering, GPU compute, or any benchmark-driven evaluation, the AMD card provides concrete, verifiable results.

The Intel Arc Pro B390, however, serves a different purpose. Its 80 W TDP, lack of power connectors, and IGP form factor make it suitable for portable devices where the RX 9070 XT's 304 W TDP, dual-slot size, and 2x 8-pin power connectors would be impossible to accommodate. The Intel part's 3 nm process, Xe3-LPG architecture, and 1536 shading units are respectable for an integrated solution, and its 7.680 TFLOPS of FP32 compute is substantial for an IGP. But without benchmark data, the database cannot quantify its real-world performance.

Users with a discrete graphics slot, a suitable power supply, and a need for maximum throughput should select the RX 9070 XT. Users constrained to integrated graphics in a portable or low-power system have no alternative in this comparison, as the AMD card cannot function in that form factor. The verdict is not a matter of preference; it is a matter of hardware capability and measured data.
