AMD Radeon RX 9070 XT vs Intel Arc B390 Comparison

Head-to-Head Benchmarks

The database contains one shared benchmark between the AMD Radeon RX 9070 XT and the Intel Arc B390: 3DMark Steel Nomad DX12. The results are decisive. The RX 9070 XT scores 7260, while the Arc B390 scores 1482. That translates to a delta of 389.9% in favor of the AMD part. In practical terms, the RX 9070 XT delivers roughly five times the raw DX12 performance of the Intel integrated GPU in this workload.

The RX 9070 XT also holds a commanding lead in the average benchmark score across all recorded tests. Its average is 13543, while the Arc B390 averages just 1482. The AMD card sits at the 55th percentile among all GPUs in the database, whereas the Intel part lands at the 9th percentile. This percentile gap underscores the fundamental difference in positioning: the RX 9070 XT is a discrete, high-end add-in card, while the Arc B390 is an integrated processor GPU.

When examining nearest rivals, the RX 9070 XT's average score of 13543 places it just 0.1% ahead of the AMD Radeon HD 7770M (13536) and 0.2% ahead of the NVIDIA GeForce GTX 570 (13515). The Arc B390's average of 1482 is 1.3% above the NVIDIA GeForce GT 520MX (1463) and 1.5% above the NVIDIA GeForce 800M (1460). These nearest-rival comparisons show that the RX 9070 XT competes with older desktop discrete GPUs, while the Arc B390 trades blows with low-end mobile and OEM parts from a decade ago.

The only head-to-head win recorded in the database goes to the RX 9070 XT, with one win and zero for the Arc B390. There are no benchmark categories where the Intel part comes out ahead. The RX 9070 XT's PassMark G3D score of 26795 dwarfs any comparable figure, and its PassMark GPU Compute score of 15864 indicates substantial compute throughput. The Arc B390 has no recorded scores in those tests, so the comparison rests solely on the Steel Nomad result.

Where Each One Wins

The RX 9070 XT wins in every measurable category where both parts have data. Its discrete design, 16 GB of dedicated GDDR6 memory, and 644.6 GB/s bandwidth make it suitable for high-resolution gaming, ray-traced workloads, and content creation. The PassMark DirectX 12 score of 78 and DirectX 11 score of 292 reflect strong API-level performance, while the Geekbench Vulkan score of 65879 indicates robust compute under modern graphics APIs.

The Arc B390, by contrast, is an integrated GPU with system-shared memory. Its only recorded benchmark, Steel Nomad DX12 at 1482, places it in the lower echelons of the database. The 9th percentile ranking means it outperforms only a small fraction of GPUs. Its nearest rivals are entry-level mobile parts, suggesting that the Arc B390 is designed for basic display output and light 2D tasks rather than demanding 3D workloads.

For users seeking maximum frame rates in modern games, the RX 9070 XT is the clear choice. Its 48.66 TFLOPS FP32 compute and 380.2 GPixel/s pixel rate provide the raw throughput needed for high-refresh 1440p or 4K gaming. The Arc B390's 7.680 TFLOPS FP32 and 60.00 GPixel/s pixel rate are roughly one-sixth and one-sixth of the AMD card respectively, confirming a massive gap in rendering capability.

Specification Differences

The two GPUs differ fundamentally in almost every specification. The RX 9070 XT uses a 4 nm TSMC process, while the Arc B390 uses a 3 nm Intel process. The AMD chip, Navi 48, contains 53,900 million transistors on a 357 mm² die, whereas the Intel chip, Panther Lake, has unknown transistor count and die size. Transistor density for the RX 9070 XT is 151.0M per mm²; no density figure exists for the Arc B390.

Memory configurations are entirely different. The RX 9070 XT has 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s bandwidth. The Arc B390 uses system-shared memory with a system-dependent bus width and bandwidth. Clock speeds also diverge sharply: the RX 9070 XT runs at 1660 MHz base, 2400 MHz game, and 2970 MHz boost, while the Arc B390 runs at 300 MHz base and 2500 MHz boost with no game clock listed.

Compute resources show a similar chasm. The RX 9070 XT packs 4096 shading units, 256 TMUs, 128 ROPs, and 64 ray tracing cores. The Arc B390 has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Pixel rate for the AMD card is 380.2 GPixel/s versus 60.00 GPixel/s for Intel. Texture rate is 760.3 GTexel/s versus 120.0 GTexel/s. FP32 throughput is 48.66 TFLOPS versus 7.680 TFLOPS, and FP16 is 48.66 TFLOPS (1:1) versus 15.36 TFLOPS (2:1).

Power and physical design also differ. The RX 9070 XT has a 304 W TDP, dual-slot cooling, two 8-pin power connectors, and a 700 W suggested PSU. The Arc B390 has an 80 W TDP, is an IGP, uses no power connectors, and has no suggested PSU. The AMD card uses PCIe 5.0 x16, while the Intel part uses IGP. Display outputs for the RX 9070 XT are 1x HDMI 2.1b and 3x DisplayPort 2.1a; the Arc B390's outputs are portable-device dependent.

Architecture Differences

The RX 9070 XT is built on RDNA 4.0, AMD's fourth-generation graphics architecture, and belongs to the Radeon RX 9000 series with the Navi IV generation. The Arc B390 uses Xe3-LPG, Intel's third-generation Xe architecture tailored for low-power graphics, and belongs to the Arc Graphics-M generation for Panther Lake. The process nodes reflect this split: TSMC's 4 nm for AMD versus Intel's 3 nm for the Arc B390.

Ray tracing hardware scales with the rest of the pipeline. The RX 9070 XT has 64 RT cores, enabling hardware-accelerated ray tracing across its 4096 shading units. The Arc B390 has 12 RT cores for its 1536 shading units. Neither GPU has tensor cores listed in the database. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists despite the enormous performance gap.

The memory architecture is the most striking architectural divergence. The RX 9070 XT relies on dedicated GDDR6 with a fixed 256-bit bus and 644.6 GB/s bandwidth, while the Arc B390 uses system-shared memory where bandwidth depends on the host platform. This means the Arc B390's performance can vary with system memory speed and capacity, whereas the RX 9070 XT has predictable, dedicated bandwidth.

Clock behavior also reveals different design goals. The RX 9070 XT has a high base clock of 1660 MHz and a boost of 2970 MHz, with a game clock of 2400 MHz as a stable sustained frequency. The Arc B390 idles at 300 MHz and boosts to 2500 MHz, but lacks a defined game clock, indicating it may spend most time at lower frequencies in real workloads. The RX 9070 XT's FP16 performance matches its FP32 at a 1:1 ratio, while the Arc B390 delivers FP16 at a 2:1 ratio, doubling throughput to 15.36 TFLOPS.

The RX 9070 XT is a discrete, dual-slot card with 304 W TDP and external power, designed for desktop gaming systems with dedicated PSU headroom. The Arc B390 is an integrated GPU with 80 W TDP, no power connectors, and no suggested PSU, intended for compact or portable systems where power efficiency and space are priorities. The production status for both is active, with the RX 9070 XT released on March 5, 2025, and the Arc B390 dated January 26, 2026.
