AMD Radeon RX 9070 vs Intel Arc Pro B70 Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the AMD Radeon RX 9070 across ten tests, while the Intel Arc Pro B70 has no benchmark entries in the current dataset. This asymmetry prevents a direct score-for-score comparison. Instead, the analysis must rely on the RX 9070’s measured performance and the B70’s architectural specifications.

The RX 9070’s average benchmark score of 23,877 places it in the 69th percentile of all GPUs in the database. Its nearest rivals, all within a 1.2% margin, are the NVIDIA GeForce RTX 2080 SUPER (average score 24,170, delta -1.2%), the AMD Radeon RX 6800S (average score 24,063, delta -0.8%), the NVIDIA GeForce GTX TITAN Z (average score 23,736, delta +0.6%), and the NVIDIA GeForce RTX 3080 Mobile (average score 23,628, delta +1.1%). The data indicates the RX 9070 sits in a tight performance cluster, with its highest recorded score being 25,381 in Passmark G3D and its lowest being 74 in Passmark DirectX 12.

For the Arc Pro B70, the database shows a 50th percentile ranking but an average benchmark score of zero, reflecting the absence of measured results. Any head-to-head claims would require extrapolation from specifications, which is not supported by the recorded data. The only definitive statement is that the RX 9070 has verified scores across multiple test suites, while the B70 has none.

Architecture Differences

The two GPUs diverge fundamentally in their underlying designs. The AMD Radeon RX 9070 uses the Navi 48 chip on the RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. It contains 53,900 million transistors on a 357 mm² die, yielding a transistor density of 151.0 million per mm². The Intel Arc Pro B70 uses the BMG-G31 chip on the Xe2-HPG architecture, also from TSMC but on a 5 nm process. Its die size is 368 mm², slightly larger than the RX 9070, though its transistor count is listed as unknown.

Clock behavior differs notably. The RX 9070 has a base clock of 1330 MHz, a boost clock of 2520 MHz, and a game clock of 2070 MHz. The B70 runs higher, with a base of 2280 MHz and a boost of 2800 MHz, but has no game clock specified. Memory clocks are close: the RX 9070 runs at 2518 MHz (20.1 Gbps effective), while the B70 runs at 2375 MHz (19 Gbps effective).

Memory configuration favors the Intel card. The RX 9070 provides 16 GB of GDDR6 on a 256-bit bus, with bandwidth of 644.6 GB/s. The B70 doubles capacity to 32 GB of GDDR6 on the same 256-bit bus, though its bandwidth is lower at 608.0 GB/s. The extra capacity comes at a slight bandwidth cost.

Compute resources show a trade-off. The RX 9070 has 3,584 shading units, 224 texture mapping units, and 128 ROPs, with 56 ray tracing cores. The B70 has more shading units (4,096), more TMUs (256), and the same 128 ROPs, but fewer ray tracing cores at 32. Pixel and texture rates reflect this: the RX 9070 achieves 322.6 GPixel/s and 564.5 GTexel/s, while the B70 reaches 358.4 GPixel/s and 716.8 GTexel/s.

Floating-point performance presents a sharp contrast. The RX 9070 delivers 36.13 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The B70 produces 22.94 TFLOPS for FP32 but 45.88 TFLOPS for FP16, a 2:1 ratio. This means the AMD card has a substantial lead in single-precision work, while the Intel card doubles its throughput in half-precision tasks.

Power and physical design differ as well. The RX 9070 has a TDP of 220 W and requires two 8-pin power connectors. The B70 has a higher TDP of 230 W but needs only a single 8-pin connector. Both cards are dual-slot and recommend a 550 W power supply. The B70’s physical dimensions are recorded: 267 mm in length, 110 mm in height, and 39 mm in width. The RX 9070 has no dimensions listed.

Display outputs are nearly identical. Both offer one HDMI port and three DisplayPort outputs, with the RX 9070 using HDMI 2.1b and DisplayPort 2.1a, while the B70 uses HDMI 2.1a and DisplayPort 2.1. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both use PCIe 5.0 x16 interfaces.

Where Each One Wins

Based on the recorded data, the Radeon RX 9070 wins in every measurable benchmark category, since the Arc Pro B70 has no recorded scores. The RX 9070’s strengths are apparent in its Passmark results: 25,381 in G3D, 14,737 in GPU compute, 1,280 in G2D, 343 in DirectX 9, 281 in DirectX 11, 141 in DirectX 10, and 74 in DirectX 12. Its 3DMark Steel Nomad DX12 score is 6,290, while Geekbench results show 131,539 in OpenCL and 58,705 in Vulkan.

The architectural data allows for qualitative distinctions. The RX 9070’s FP32 throughput of 36.13 TFLOPS is well above the B70’s 22.94 TFLOPS, suggesting faster conventional rendering and compute workloads that rely on single-precision math. Its higher memory bandwidth of 644.6 GB/s versus 608.0 GB/s gives it an edge in bandwidth-sensitive scenarios, though the B70’s 32 GB capacity could benefit workloads requiring large datasets that exceed 16 GB.

The B70’s advantages are evident in its specifications. Its 4,096 shading units and 256 TMUs exceed the RX 9070’s counts, and its FP16 throughput of 45.88 TFLOPS is higher than the RX 9070’s 36.13 TFLOPS. This indicates the Intel card is designed for mixed-precision workloads where half-precision math dominates. Its higher boost clock of 2800 MHz also suggests strong burst performance, and its larger memory pool of 32 GB is a clear capacity win.

The Verdict

The data presents a clear split. For users prioritizing measured performance, the AMD Radeon RX 9070 is the only card with verified benchmark results, and those results place it near the RTX 2080 SUPER and RX 6800S in average score. Its FP32 performance is 57% higher than the B70’s, and its memory bandwidth is 6% higher. The RX 9070 also has a lower TDP of 220 W versus 230 W, and it carries a launch MSRP of 549 USD.

The Intel Arc Pro B70, with a launch MSRP of 949 USD, targets a different profile. Its 32 GB memory capacity doubles the RX 9070’s 16 GB, and its FP16 throughput exceeds the AMD card’s by 27%. Its single 8-pin power connector simplifies installation, and its higher base and boost clocks suggest strong frequency behavior. However, without any benchmark scores in the database, its real-world performance cannot be assessed from the recorded data.

The choice depends on workload. The RX 9070 suits applications that require proven single-precision compute and higher bandwidth, with the data confirming its position in the 69th percentile. The B70 appeals to scenarios needing large memory capacity or half-precision throughput, but its lack of recorded benchmarks means its performance claims rest entirely on specifications. The recorded data cannot validate the B70’s capabilities, so the RX 9070 stands as the only verified performer in this comparison.
