AMD Radeon RX 9070 XT vs Intel Arc B370 Comparison

The Verdict

The data in this comparison is unambiguous. The AMD Radeon RX 9070 XT holds a massive performance advantage over the Intel Arc B370 in the only benchmark shared by both products. The 3DMark Steel Nomad DX12 test shows the AMD card scoring 7260 points against 1184 points for the Intel part, a delta of 513.2% in favor of AMD. The RX 9070 XT sits at the 55th percentile among all GPUs in the database, while the Arc B370 ranks at the 5th percentile. The RX 9070 XT is a discrete, dual-slot add-in board with 16 GB of dedicated GDDR6 memory, a 256-bit bus, and 644.6 GB/s of bandwidth. The Arc B370 is an integrated graphics processor with system-shared memory, designed for portable devices. Buyers seeking discrete-class gaming performance should choose the RX 9070 XT. The Arc B370 serves a completely different role as an IGP for lightweight, power-constrained systems.

Architecture Differences

The two products come from different foundries and process nodes. AMD builds the RX 9070 XT on TSMC's 4 nm process, while Intel fabricates the Arc B370 on its own 3 nm node. The AMD chip, codenamed Navi 48, uses the RDNA 4.0 architecture and belongs to the Navi IV (RX 9000) generation. The Intel part, codenamed Panther Lake, uses the Xe3-LPG architecture and belongs to the Arc Graphics-M (Panther Lake) generation.

Transistor counts differ sharply. The Navi 48 die packs 53,900 million transistors across a 357 mm² die, yielding a transistor density of 151.0 million per square millimeter. The Intel chip lists its transistor count, die size, and density as unknown, so no direct comparison of those figures is possible from the recorded data.

The RX 9070 XT features 4096 shading units, 256 texture mapping units, 128 ROPs, and 64 ray tracing cores. The Arc B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. Clock behavior also differs. The AMD card has a base clock of 1660 MHz, a boost clock of 2970 MHz, and a game clock of 2400 MHz. The Intel IGP runs at a base of 300 MHz and boosts to 2400 MHz. Memory configurations are fundamentally different: the RX 9070 XT uses 16 GB of GDDR6 on a 256-bit bus with 644.6 GB/s bandwidth, while the Arc B370 shares system memory with bandwidth described as system dependent.

Compute throughput favors AMD heavily. The RX 9070 XT delivers 48.66 TFLOPS of FP32 performance and the same 48.66 TFLOPS of FP16 (1:1 ratio). The Arc B370 produces 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1 ratio). Pixel and texture rates follow the same pattern: 380.2 GPixel/s and 760.3 GTexel/s for AMD versus 48.00 GPixel/s and 96.00 GTexel/s for Intel.

Power and physical design separate the two completely. The RX 9070 XT consumes 304 W, requires two 8-pin power connectors, and needs a 700 W power supply. It occupies a dual-slot form factor and connects via PCIe 5.0 x16. The Arc B370 draws 25 W, uses no external power connectors, has no suggested PSU rating, and is an IGP with no slot width or bus interface beyond the integrated design. Display outputs on the AMD card include one HDMI 2.1b port and three DisplayPort 2.1a outputs, while the Intel part's outputs are portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release timing also differs. The RX 9070 XT launched on 2025-03-05 and lists a launch MSRP of 599 USD. The Arc B370 launched on 2026-01-26 and has no launch MSRP recorded. AMD's predecessor is Navi III; Intel lists no predecessor. Both production statuses are active.

Head-to-Head Benchmarks

The single shared benchmark between these two products is 3DMark Steel Nomad DX12. The RX 9070 XT scores 7260, while the Arc B370 scores 1184. The delta is 513.2% in favor of AMD, meaning the RX 9070 XT delivers roughly six times the performance of the Intel IGP in this test. The Arc B370 records zero wins across all head-to-head comparisons; AMD takes the sole test.

The average benchmark score for the RX 9070 XT is 13543 across its full benchmark suite, which includes 3DMark Steel Nomad DX12, Geekbench OpenCL, Geekbench Vulkan, and multiple Passmark tests. The Arc B370 has only one recorded benchmark score, 1184, which also serves as its average. The RX 9070 XT's nearest rivals by average score are the AMD Radeon HD 7770M at 13536 (0.1% behind), the NVIDIA GeForce GTX 570 at 13515 (0.2% behind), the NVIDIA P106-090 at 13470 (0.5% behind), and the AMD Radeon Pro 555 at 13407 (1% behind). The Arc B370's nearest rivals are the ATI Mobility Radeon HD 5570 at 1186 (0.2% ahead of the Intel part), the ATI Radeon HD 5770 at 1190 (0.5% ahead), the AMD Radeon HD 7650M at 1192 (0.7% ahead), and the AMD FirePro M2000 at 1168 (1.4% behind).

An important context issue appears in the database: the RX 9070 XT's nearest rivals are all older, lower-end GPUs with average scores near 13500, despite the RX 9070 XT's own average of 13543. The percentile ranking of 55 places it just above the midpoint of all GPUs in the database. The Arc B370's 5th percentile ranking places it near the bottom of the entire GPU population tracked by the database.

Where Each One Wins

The RX 9070 XT wins in every measurable performance category from the recorded data. It dominates the single head-to-head benchmark, 3DMark Steel Nomad DX12, with a 513.2% lead. It has more shading units (4096 versus 1280), more TMUs (256 versus 40), more ROPs (128 versus 20), and more ray tracing cores (64 versus 10). Its FP32 throughput of 48.66 TFLOPS is roughly eight times the Arc B370's 6.144 TFLOPS. Its pixel rate of 380.2 GPixel/s and texture rate of 760.3 GTexel/s dwarf the Intel part's 48.00 GPixel/s and 96.00 GTexel/s. The RX 9070 XT also has dedicated memory with 644.6 GB/s of bandwidth, whereas the Arc B370 depends on system memory with bandwidth described only as system dependent.

The Arc B370 wins in power efficiency and physical integration. Its 25 W TDP is a fraction of the RX 9070 XT's 304 W. It requires no power connectors, no extra PCIe slot, and no dedicated power supply rating. It is an IGP, meaning it fits into portable devices without any add-in card. The 3 nm Intel process node is smaller than the 4 nm TSMC node used by AMD, though the Intel chip's transistor count and die size are unknown. The Arc B370 also has a later release date of 2026-01-26 compared to the RX 9070 XT's 2025-03-05.

For users building a desktop with a dedicated graphics card, the RX 9070 XT is the only viable choice from this comparison. Its benchmark lead is overwhelming, and its 55th percentile ranking among all GPUs, while modest, is far above the Arc B370's 5th percentile. The RX 9070 XT's nearest rivals in average score are older parts like the GTX 570 and Radeon HD 7770M, which indicates its average score of 13543 places it in a mid-range bracket despite its strong individual benchmark results. The Arc B370's nearest rivals are all legacy parts from over a decade ago, confirming its position near the bottom of the database's GPU rankings.

The use case split is therefore straightforward. The RX 9070 XT suits desktop systems requiring discrete rendering performance, ray tracing hardware, and high-bandwidth dedicated memory. The Arc B370 suits ultraportable or integrated systems where the 25 W power draw, lack of external connectors, and IGP form factor are the defining characteristics. Neither product competes in the other's intended segment.
