The raw compute data indicates that the RX 7900M holds a 68% advantage in FP32 throughput over the Arc Pro B70, delivering 38.52 TFLOPS versus 22.94 TFLOPS. In FP16 compute, the AMD card's 77.05 TFLOPS is 68% higher than the Intel card's 45.88 TFLOPS. The RX 7900M also has 125% more ray tracing cores (72 versus 32) and 50% more ROPs (192 versus 128). The AMD card has 12.5% more shading units (4608 versus 4096) and 12.5% more TMUs (288 versus 256).

The Intel Arc Pro B70 counters with advantages in several specification areas. Its 2800 MHz boost clock is 34% higher than the RX 7900M's 2090 MHz boost clock. Its texture rate of 716.8 GTexel/s is 19% higher than the AMD card's 601.9 GTexel/s. Memory bandwidth is 5.6% higher at 608.0 GB/s versus 576.0 GB/s. Memory capacity is doubled at 32 GB versus 16 GB. The Intel card uses a newer PCIe 5.0 x16 interface compared to PCIe 4.0 x16 on the AMD card.

The Arc Pro B70 has no benchmark entries, which means the database cannot verify its actual performance in workloads. Its 50th percentile ranking and zero average benchmark score indicate that no measured performance data exists for this GPU. In contrast, the RX 7900M has verified scores across three different benchmark tests, giving it a concrete performance profile. The RX 7900M's nearest rival data shows it sits within 6.3% of the NVIDIA RTX A4500 and 5.4% ahead of the AMD Radeon Instinct MI60, providing a reference frame for its capabilities.

The specification comparison shows a clear trade-off. The RX 7900M delivers higher raw compute throughput, more ray tracing hardware, and a better established benchmark record. The Arc Pro B70 provides more memory, higher clocks, and a newer bus interface, but without benchmark scores, its practical performance remains unverified in the database. The RX 7900M's recorded scores in DirectX 12, OpenCL, and Vulkan tests establish a measurable performance baseline, while the Arc Pro B70's empty benchmark array leaves its performance claims unsupported by data.
