Intel Arc Pro B390 vs NVIDIA GeForce RTX 4070 Ti Comparison

Intel Arc Pro B390 and NVIDIA GeForce RTX 4070 Ti occupy opposite ends of the graphics spectrum, one an integrated processor graphics solution and the other a dedicated dual-slot expansion card. The recorded data shows a decisive performance gap, with the RTX 4070 Ti delivering roughly 5.8 times the average benchmark score of the Arc Pro B390. The Arc Pro B390 sits at the 50th percentile among all GPUs in the database, while the RTX 4070 Ti ranks at the 84th percentile, placing it well above the majority of recorded graphics hardware.

Where Each One Wins

The use-case split is defined by the physical and architectural limits of each part. The Intel Arc Pro B390 is an integrated graphics processor with no dedicated memory, no power connectors, and an 80 W total board power. It is designed for portable devices, with display outputs listed as "Portable Device Dependent." Its strengths lie in basic graphical output, video decode, and light compute workloads rather than high-end gaming or professional 3D rendering. The data shows no recorded benchmark scores for the Arc Pro B390, meaning the database has no direct measurements of its real-world performance in any test.

The NVIDIA GeForce RTX 4070 Ti wins in every measurable category where data exists. It carries 12 GB of GDDR6X memory on a 192-bit bus, with 504.2 GB/s of bandwidth. Its recorded benchmark results span DirectX 9 through DirectX 12, OpenCL, Vulkan, and compute workloads. The PassMark G3D score of 31,624 and the Geekbench Vulkan score of 213,808 indicate strong performance across both legacy and modern graphics APIs. The RTX 4070 Ti also holds an average benchmark score of 44,795, placing it in the 84th percentile of all GPUs in the database. The Arc Pro B390, with no recorded benchmark entries, cannot claim a single workload victory in the available data.

Architecture Differences

The two processors use fundamentally different designs. Intel's Arc Pro B390 is built on the Panther Lake chip using the Xe3-LPG architecture, manufactured on a 3 nm process at Intel. The RTX 4070 Ti uses the AD104 chip with Ada Lovelace architecture, manufactured on a 5 nm process at TSMC. The process node difference alone does not determine performance, but the scale of each chip does: the RTX 4070 Ti contains 35,800 million transistors across a 294 mm² die, with a transistor density of 121.8M per mm². Intel does not disclose transistor count, die size, or density for the Arc Pro B390.

The compute resources differ by a factor of five or more. The Arc Pro B390 has 1,536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The RTX 4070 Ti has 7,680 shading units, 240 TMUs, 80 ROPs, and 60 RT cores, plus 240 tensor cores that the Intel part lacks entirely. The NVIDIA part also uses dedicated GDDR6X memory, while the Intel part shares system memory with the CPU, making bandwidth "System Dependent" and effectively variable based on the host platform.

Clock behavior also differs. The Arc Pro B390 runs at a 300 MHz base clock and boosts to 2500 MHz. The RTX 4070 Ti runs at a 2310 MHz base clock and boosts to 2610 MHz. The Intel part has a higher boost multiplier relative to its base, but the NVIDIA part starts from a much higher floor. The RTX 4070 Ti's memory clock is listed at 1313 MHz with 21 Gbps effective data rate, while the Arc Pro B390's memory clock is "System Shared" with no fixed figure.

Head-to-Head Benchmarks

The RTX 4070 Ti holds a comprehensive lead across all recorded tests. In PassMark DirectX 9, it scores 352. In DirectX 10, it scores 187. In DirectX 11, it scores 288. In DirectX 12, it scores 116. These scores indicate that the card handles legacy APIs adequately but scales best in modern workloads. The PassMark G3D score of 31,624 is the card's strongest overall graphics result, while the PassMark G2D score of 1,200 reflects 2D desktop and compositing performance.

Compute and API-level tests show the RTX 4070 Ti's raw throughput. Geekbench OpenCL returns 176,953, and Geekbench Vulkan returns 213,808. The PassMark GPU Compute score of 18,396 confirms strong general-purpose compute capability. The 3DMark Steel Nomad DX12 score of 5,024 places the card in a solid position for modern DirectX 12 titles. The average benchmark score of 44,795 across all recorded tests puts it near the NVIDIA GeForce RTX 5090 Mobile, which averages 45,152, a difference of only 0.8%. It sits 1.3% behind the AMD Radeon Pro 5500 XT at 45,384 and 1.7% behind the Intel Arc A730M at 45,592, while running 1.6% ahead of the NVIDIA RTX A6000 at 44,075.

The Arc Pro B390 has no benchmark entries in the database, so no direct head-to-head scores exist. The available information shows its peak theoretical rates: 60.00 GPixel/s pixel throughput, 120.0 GTexel/s texture fill, 7.680 TFLOPS FP32, and 15.36 TFLOPS FP16 at a 2:1 ratio. The RTX 4070 Ti delivers 208.8 GPixel/s, 626.4 GTexel/s, and 40.09 TFLOPS for both FP32 and FP16 at a 1:1 ratio. The NVIDIA part's FP32 throughput is 5.2 times higher than the Intel part, and its texture rate is 5.2 times higher as well.

Specification Differences

The two parts differ across nearly every recorded specification field. The Arc Pro B390 is an integrated GPU on a 3 nm Intel process, while the RTX 4070 Ti is a dual-slot discrete card on a 5 nm TSMC process.
