Architecture Differences

The Intel Arc Pro B390 and NVIDIA GeForce RTX 5070 Ti represent fundamentally different design philosophies. Intel's part is built on the Xe3-LPG architecture, fabricated on a 3 nm process at Intel, using the Panther Lake chip. This is an integrated GPU, meaning it shares memory with the system rather than using dedicated VRAM. The architecture is part of the Arc Graphics-WM (Panther Lake) generation, and it replaces the HD Graphics-WM line.

NVIDIA's GeForce RTX 5070 Ti uses the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The GB203 chip contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6M per mm². This is a discrete, dual-slot add-in card that connects via PCIe 5.0 x16. It is part of the GeForce 50-series, succeeding the GeForce 40 series and preceding the GeForce 60 series.

The compute resources differ dramatically. The Intel Arc Pro B390 has 1,536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. It has no dedicated tensor cores listed. The NVIDIA card offers 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. These raw counts explain the large gap in theoretical throughput: the Arc Pro B390 delivers 7.680 TFLOPS of FP32 performance, while the RTX 5070 Ti delivers 43.94 TFLOPS.

Memory architecture is another major divider. The Intel part relies on system-shared memory, with bandwidth and bus width described as system dependent. The RTX 5070 Ti has 16 GB of GDDR7 memory on a 256-bit bus, providing 896.0 GB/s of bandwidth. The NVIDIA card also runs its memory at 1750 MHz with 28 Gbps effective speed.

Clock behavior also differs. The Intel GPU has a base clock of 300 MHz and a boost clock of 2500 MHz. The NVIDIA GPU has a much higher base clock of 2295 MHz and a boost of 2452 MHz. Despite the lower boost, the NVIDIA card's massive shading unit count gives it the performance edge.

Pixel and texture rates reflect the hardware differences. The Arc Pro B390 achieves 60.00 GPixel/s and 120.0 GTexel/s. The RTX 5070 Ti achieves 235.4 GPixel/s and 686.6 GTexel/s. The FP16 output also differs: Intel lists 15.36 TFLOPS with a 2:1 ratio, while NVIDIA lists 43.94 TFLOPS with a 1:1 ratio.

The Verdict

The data in the database shows a clear performance hierarchy. The NVIDIA GeForce RTX 5070 Ti occupies the 86th percentile of all GPUs, with an average benchmark score of 49,957. The Intel Arc Pro B390 sits at the 50th percentile with no recorded benchmark scores and an average score of zero.

For users who need raw compute and gaming performance, the RTX 5070 Ti is the only option with measured results. Its nearest rivals in the database include the AMD Radeon RX Vega 64 at 50,001 (0.1% lower), the Intel Arc A550M at 49,737 (0.4% higher), the AMD Radeon RX 6900 XT at 50,951 (2% higher), and the AMD Radeon RX 6800 XT at 48,477 (3.1% lower). These deltas show the RTX 5070 Ti sits in a competitive band near the top of the previous generation.

The Intel Arc Pro B390, as an integrated GPU with a 300 MHz base clock and 80 W TDP, is designed for a different segment entirely. Its system-shared memory, lack of power connectors, and IGP bus interface indicate it targets portable or low-power devices. Users who require a discrete card with dedicated VRAM and a 700 W power supply should look at the NVIDIA part.

There is no benchmark overlap in the database, so direct head-to-head comparisons rely on the recorded specifications. The RTX 5070 Ti delivers 5.7 times the FP32 throughput, 3.9 times the pixel rate, and 5.7 times the texture rate of the Arc Pro B390. The NVIDIA card also has 16 GB of dedicated GDDR7 memory versus shared system memory.

The choice depends on the use case. For a system requiring an integrated GPU with no additional power connectors, the Arc Pro B390 fits. For a high-performance desktop with a 700 W power supply and PCIe 5.0 slot, the RTX 5070 Ti is the measured performer.

Specification Differences

The two GPUs differ in nearly every major specification category. The Intel Arc Pro B390 uses the Xe3-LPG architecture on a 3 nm process at Intel, while the NVIDIA GeForce RTX 5070 Ti uses Blackwell 2.0 on a 5 nm process at TSMC. The NVIDIA chip has 45,600 million transistors on a 378 mm² die, while Intel's transistor count and die size are listed as unknown.

Clock speeds differ significantly. Intel's base clock is 300 MHz with a 2500 MHz boost. NVIDIA's base clock is 2295 MHz with a 2452 MHz boost. Memory clocks also differ: the Intel part uses system-shared memory, while NVIDIA uses 1750 MHz with 28 Gbps effective.

Memory capacity and type show the biggest gap. Intel uses system-shared memory with system-dependent bandwidth. NVIDIA provides 16 GB of GDDR7 on a 256-bit bus with 896.0 GB/s bandwidth.

Compute units diverge sharply. Intel has 1,536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores, with no tensor cores listed. NVIDIA has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores.

Theoretical performance numbers favor NVIDIA. Intel achieves 60.00 GPixel/s, 120.0 GTexel/s, 7.680 TFLOPS FP32, and 15.36 TFLOPS FP16 (2:1). NVIDIA achieves 235.4 GPixel/s, 686.6 GTexel/s, 43.94 TFLOPS FP32, and 43.94 TFLOPS FP16 (1:1).

Power and physical specifications also differ. Intel has an 80 W TDP, is an IGP with no power connectors, and uses an IGP bus interface. NVIDIA has a 300 W TDP, is dual-slot, uses a 1x 16-pin power connector, requires a 700 W suggested PSU, and uses PCIe 5.0 x16.

Display outputs differ. Intel's outputs are portable device dependent. NVIDIA provides 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Dimensions only exist for NVIDIA: 304 mm length, 137 mm height, and 48 mm width. Intel has no recorded dimensions.

Release dates differ: NVIDIA launched on February 19, 2025, and Intel on January 26, 2026. NVIDIA has a successor (GeForce 60) and a predecessor (GeForce 40). Intel has a predecessor (HD Graphics-WM) and no successor.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the Intel Arc Pro B390 and the NVIDIA GeForce RTX 5070 Ti. The Intel part has no recorded benchmark scores in any test. The NVIDIA part has ten recorded benchmark scores across multiple suites.

In 3DMark Steel Nomad DX12, the RTX 5070 Ti scores 6,604. In Geekbench OpenCL, it scores 212,363, and in Geekbench Vulkan, it scores 225,122. Passmark results show 192 in DirectX 10, 300 in DirectX 11, 127 in DirectX 12, and 351 in DirectX 9. Passmark G2D scores 1,332, G3D scores 32,974, and GPU Compute scores 20,203.

The average benchmark score for the RTX 5070 Ti is 49,957, placing it at the 86th percentile of all GPUs. Its nearest rivals in the database provide context. The AMD Radeon RX Vega 64 scores 50,001, which is 0.1% higher. The Intel Arc A550M scores 49,737, which is 0.4% lower. The AMD Radeon RX 6900 XT scores 50,951, which is 2% higher. The AMD Radeon RX 6800 XT scores 48,477, which is 3.1% lower.

Since the Intel Arc Pro B390 has no benchmark entries, the only comparative data comes from specifications. The RTX 5070 Ti's FP32 throughput of 43.94 TFLOPS is 5.7 times the Arc Pro B390's 7.680 TFLOPS. The pixel rate of 235.4 GPixel/s is 3.9 times Intel's 60.00 GPixel/s. The texture rate of 686.6 GTexel/s is 5.7 times Intel's 120.0 GTexel/s.

The RTX 5070 Ti also wins on memory bandwidth, delivering 896.0 GB/s versus Intel's system-dependent bandwidth. The NVIDIA card's 16 GB of GDDR7 memory is dedicated, while the Intel part must share system memory. The RTX 5070 Ti has 70 RT cores versus Intel's 12, and 280 tensor cores versus none listed.

The gap in shading units is substantial: 8,960 versus 1,536, a factor of 5.8. TMUs and ROPs also favor NVIDIA by factors of 5.8 and 4.0 respectively. The RTX 5070 Ti's 300 W TDP versus Intel's 80 W TDP reflects the performance differential, though the Intel part's integrated nature makes direct power comparisons less meaningful.

The recorded data confirms that the RTX 5070 Ti is a high-performance discrete GPU, while the Arc Pro B390 is a low-power integrated solution. Without benchmark scores for the Intel part, the database cannot quantify its real-world performance, but the specification gaps provide a clear picture of the performance hierarchy.
