Architecture Differences

The fundamental architectural split between these two processors is substantial. The AMD Radeon RX 9070 XT is a discrete, high-performance add-in board powered by the Navi 48 chip on the RDNA 4.0 architecture. It uses a 4 nm TSMC process and integrates 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million transistors per square millimeter. The Intel Arc Pro B370, in contrast, is an integrated graphics processor built on the Xe3-LPG architecture with the Panther Lake chip, fabricated on Intel's own 3 nm process. Its transistor count and die size are listed as unknown in the database.

Compute resource allocation differs sharply. The RX 9070 XT fields 4096 shading units, 256 TMUs, 128 ROPs, and 64 ray tracing cores. The Arc Pro B370 offers 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. This is a 3.2x advantage in shading units for AMD and a 6.4x advantage in ROPs. The pixel rate tells the story clearly: the RX 9070 XT achieves 380.2 GPixel/s versus 48.00 GPixel/s for the Intel part.

Clock behavior also reflects their different roles. 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 B370 has a very low 300 MHz base clock but a 2400 MHz boost clock, indicating aggressive power management for an integrated part. Memory clocks are likewise different: the RX 9070 XT runs at 2518 MHz with 20.1 Gbps effective, while the Arc Pro B370 relies on system shared memory.

The floating-point throughput gap is enormous. The RX 9070 XT delivers 48.66 TFLOPS of FP32 and 48.66 TFLOPS of FP16 at a 1:1 ratio. The Arc Pro B370 provides 6.144 TFLOPS of FP32 and 12.29 TFLOPS of FP16 at a 2:1 ratio. The Intel part's FP16 advantage relative to its own FP32 reflects a different compute path, but the absolute numbers remain far lower.

Both GPUs support the same API level: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, their physical form factors are opposite ends of the spectrum. The RX 9070 XT is dual-slot, uses PCIe 5.0 x16, and has 1x HDMI 2.1b plus 3x DisplayPort 2.1a outputs. The Arc Pro B370 is an IGP with no dedicated power connectors, no slot width beyond integrated, and display outputs that are portable device dependent.

Where Each One Wins

The recorded data shows no overlap in benchmark presence. The RX 9070 XT has ten benchmark entries, while the Arc Pro B370 has zero recorded benchmarks in the database. This makes direct performance comparison impossible from measured results. However, the specification data indicates clear use-case separation.

The RX 9070 XT is positioned for high-throughput rendering and compute workloads. Its 16 GB of dedicated GDDR6 memory, 256-bit bus, and 644.6 GB/s bandwidth support large textures and heavy data movement. The 48.66 TFLOPS FP32 throughput and 380.2 GPixel/s pixel rate suit demanding gaming and professional 3D rendering scenarios. The 64 ray tracing cores provide dedicated hardware for ray-traced effects.

The Arc Pro B370 is a low-power integrated solution with a 25 W TDP. Its system shared memory approach means bandwidth and capacity depend entirely on the host system's memory configuration. The 6.144 TFLOPS FP32 output and 48.00 GPixel/s pixel rate are sufficient for basic graphics and light compute on portable devices. The 2:1 FP16 ratio (12.29 TFLOPS) suggests some acceleration for half-precision workloads, but the absolute numbers remain modest.

The production status for both is "Active", meaning both are current products in the database. The RX 9070 XT has a predecessor listed as Navi III, while the Arc Pro B370 succeeds HD Graphics-WM. This indicates both are part of ongoing product lines, but they target entirely different market segments: discrete desktop performance versus integrated mobile capability.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs, and the Arc Pro B370 has no individual benchmark scores recorded. The wins counters show zero for both sides. This means a direct numerical comparison of measured performance is not possible from the recorded data.

What can be analyzed are the aggregate metrics. The RX 9070 XT has an average benchmark score of 13543 across its ten tests, placing it in the 55th percentile of all GPUs in the database. Its nearest rivals, all with very similar average scores, include the AMD Radeon HD 7770M at 13536 (0.1% delta), the NVIDIA GeForce GTX 570 at 13515 (0.2% delta), the NVIDIA P106-090 at 13470 (0.5% delta), and the AMD Radeon Pro 555 at 13407 (1% delta). This clustering indicates the RX 9070 XT's average performance sits in a narrow band around these older or lower-tier discrete parts, despite its modern architecture and high specifications.

Individual RX 9070 XT benchmark results show significant variance across tests. The highest score is 65879 in Geekbench Vulkan, followed by 26795 in Passmark G3D. The lowest scores are 78 in Passmark DirectX 12 and 154 in Passmark DirectX 10. The Passmark DirectX 11 score is 292, DirectX 9 is 353, and G2D is 1328. The GPU compute score is 15864, and the OpenCL score from Geekbench is 17428. The 3DMark Steel Nomad DX12 score is 7260.

The Arc Pro B370 has an average benchmark score of 0 and a 50th percentile ranking, with no entries in the benchmark list and no nearest rivals recorded. This makes any quantitative comparison with the RX 9070 XT impossible from measured data. The specification differences, however, suggest a performance gap of roughly 8x in FP32 throughput (48.66 TFLOPS versus 6.144 TFLOPS), an almost 8x gap in pixel rate (380.2 versus 48.00 GPixel/s), and a similar gap in texture rate (760.3 versus 96.00 GTexel/s).

The RX 9070 XT's launch MSRP was 599 USD. The Arc Pro B370 has no recorded launch MSRP. Given the absence of benchmark data for the Intel part, the recorded information supports only the conclusion that the RX 9070 XT is a high-throughput discrete GPU with a substantial specification advantage, while the Arc Pro B370 is a low-power integrated graphics solution whose measured performance has not yet been cataloged in the database.
