Head-to-Head Benchmarks

The database records no benchmark scores and no wins for either GPU in a head-to-head comparison, so the analysis relies on the specification-derived performance metrics. The NVIDIA RTX 500 Mobile Ada Generation leads in raw compute throughput. Its FP32 output of 8.294 TFLOPS is 8% higher than the Intel Arc Pro B390's 7.680 TFLOPS. The pixel rate favors NVIDIA at 64.80 GPixel/s versus 60.00 GPixel/s, a 4.80 GPixel/s advantage. Texture rate also favors NVIDIA at 129.6 GTexel/s versus 120.0 GTexel/s, a 9.6 GTexel/s advantage. The NVIDIA part has 512 more shading units, 16 more TMUs, 8 more ROPs, 4 more RT cores, and 64 tensor cores where Intel lists none. The NVIDIA part's dedicated 4 GB GDDR6 memory with 128.0 GB/s bandwidth provides a fixed memory performance ceiling, while the Intel part's system shared memory has system dependent bandwidth, meaning its memory performance varies with the host platform.

The Intel Arc Pro B390 counters in clock speed and FP16 throughput. Its boost clock of 2500 MHz is 475 MHz higher than NVIDIA's 2025 MHz. Its FP16 output of 15.36 TFLOPS at a 2:1 ratio is nearly double the NVIDIA part's 8.294 TFLOPS at a 1:1 ratio. The Intel part uses a newer 3 nm process versus NVIDIA's 5 nm process, which indicates a denser manufacturing technology. The Intel part's 80 W TDP is higher than NVIDIA's 35 W TDP, meaning the NVIDIA part delivers its higher FP32, pixel, and texture rates at less than half the power draw. The NVIDIA part also has a much higher base clock of 1485 MHz versus 300 MHz, indicating it sustains performance at idle-to-moderate loads far better than the Intel part. The Intel part's 300 MHz base clock is very low, suggesting it relies heavily on boost behavior for performance.

The data shows NVIDIA holds the advantage in every performance metric that matters for real-time graphics and compute workloads: FP32 throughput, pixel fill, texture fill, ray tracing core count, and tensor core availability. The Intel part's FP16 advantage is useful for mixed-precision workloads that can use 2:1 ratio throughput, but the 1:1 ratio on NVIDIA means its FP16 performance equals its FP32 performance, which is a different design tradeoff. The NVIDIA part's transistor count of 18,900 million on 159 mm² gives it a density of 118.9M / mm², while the Intel part's transistor count is unknown, so density comparisons cannot be made. The RTX 500 Mobile Ada Generation's PCIe 4.0 x8 interface allows it to be a discrete GPU, while the Arc Pro B390's IGP interface means it is integrated into the processor. The NVIDIA part's earlier release date of 2024-02-25 versus Intel's 2026-01-26 suggests the NVIDIA design is earlier in its lifecycle. Both parts are listed as Active in production status. The database shows both at the 50th percentile, but with no recorded benchmark scores, the percentile ranking does not differentiate them. The specification data indicates the NVIDIA RTX 500 Mobile Ada Generation is the higher-performing part across the majority of measured metrics.
