Intel Arc B390 vs NVIDIA GeForce RTX 4070 Ti SUPER AD102 Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between these two parts. The Intel Arc B390 and the NVIDIA GeForce RTX 4070 Ti SUPER AD102 do not compete in the same performance class, and their respective wins reflect entirely different use cases.

The NVIDIA GeForce RTX 4070 Ti SUPER AD102 wins the only head-to-head benchmark recorded in the database: 3DMark Steel Nomad DX12. Its score of 6269.5 dominates the Intel Arc B390's 1482, a delta of -76.4% from the Intel part's perspective. That single result places the NVIDIA card in the 36th percentile among all GPUs, while the Intel Arc B390 sits at the 9th percentile. The gap is not marginal; it spans the entire mid-range and upper-mid-range of the database's performance distribution.

The Intel Arc B390 wins in a different sense. It is an integrated graphics processor (IGP) built for mobile Panther Lake platforms. Its 80 W TDP, lack of any power connectors, and system-shared memory mean it occupies a space where discrete graphics cards cannot go: thin-and-light notebooks and portable devices. The NVIDIA part, by contrast, is a triple-slot, 285 W discrete card requiring a 16-pin power connector and a 600 W suggested PSU.

So the use-case split is stark. For raw 3D rendering performance in a desktop or high-end laptop, the NVIDIA card is the only option with meaningful results. For integrated, low-power, portable graphics, the Intel part is the relevant solution. They are not substitutes for each other; they answer different engineering questions.

Architecture Differences

The two parts come from different foundries, process nodes, and architectural lineages.

The Intel Arc B390 uses the Panther Lake chip, built on Intel's 3 nm process. Its architecture is Xe3-LPG, part of the Arc Graphics-M (Panther Lake) generation. The NVIDIA GeForce RTX 4070 Ti SUPER AD102 uses the AD102 chip, built on TSMC's 5 nm process, with the Ada Lovelace architecture from the GeForce 40-series.

Core counts differ massively. The Intel part has 1536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. It has no dedicated tensor core count listed in the database. The NVIDIA part has 8448 shading units, 264 TMUs, 96 ROPs, 66 RT cores, and 264 tensor cores. That is roughly 5.5 times the shading units, 5.5 times the TMUs, 4 times the ROPs, and 5.5 times the RT cores.

Clock behavior also differs. The Intel part runs at a 300 MHz base and 2500 MHz boost. The NVIDIA part runs at a 2340 MHz base and 2610 MHz boost. The NVIDIA card's higher base clock is especially notable: it starts above the Intel part's boost.

Memory is where the architectures diverge most visibly. The Intel Arc B390 uses system-shared memory, with the type, bus width, and bandwidth all listed as "System Shared" or "System Dependent." The NVIDIA card has 16 GB of GDDR6X on a 256-bit bus with 672.3 GB/s of bandwidth. That dedicated memory subsystem is central to the NVIDIA part's performance advantage in the Steel Nomad test.

Transistor counts and die sizes are only recorded for the NVIDIA part: 76,300 million transistors on a 609 mm² die, with a transistor density of 125.3M per mm². The Intel part's transistor count and die size are listed as unknown. The NVIDIA card also specifies a 1313 MHz memory clock with 21 Gbps effective data rate.

Feature sets for APIs are identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Intel part is "Portable Device Dependent," while the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. The bus interface also differs: the Intel part uses IGP, while the NVIDIA card uses PCIe 4.0 x16.

Pixel and texture rates reinforce the gap. The Intel part delivers 60.00 GPixel/s and 120.0 GTexel/s. The NVIDIA part delivers 250.6 GPixel/s and 689.0 GTexel/s. FP32 throughput is 7.680 TFLOPS for Intel versus 44.10 TFLOPS for NVIDIA. FP16 is 15.36 TFLOPS (2:1) for Intel versus 44.10 TFLOPS (1:1) for NVIDIA.

The Verdict

The data indicates that the NVIDIA GeForce RTX 4070 Ti SUPER AD102 is the decisive winner in every recorded performance metric. Its Steel Nomad score of 6269.5 is 4.2 times higher than the Intel Arc B390's 1482. The percentile standings confirm this: 36th versus 9th among all GPUs. The NVIDIA card also has 44.10 TFLOPS of FP32 versus 7.680 TFLOPS, 16 GB of dedicated GDDR6X versus system-shared memory, and 66 RT cores versus 12.

The Intel Arc B390 wins on power and integration. Its 80 W TDP is a fraction of the NVIDIA card's 285 W. It requires no power connector and uses the IGP bus interface, making it suitable for portable devices where the triple-slot, 310 mm long NVIDIA card cannot physically exist. The Intel part also uses a more advanced 3 nm process versus the NVIDIA card's 5 nm.

The production status differs too. The Intel part is listed as Active with a release date of January 26, 2026. The NVIDIA card is listed as End-of-life with a release date of June 9, 2024, and a predecessor in GeForce 30 and successor in GeForce 50.

For any user needing discrete 3D performance, the NVIDIA card is the only choice based on the recorded data. For any user needing integrated graphics in a low-power portable system, the Intel part is the only option. The launch MSRP for the NVIDIA card is 799 USD.

Head-to-Head Benchmarks

The only recorded head-to-head benchmark is 3DMark Steel Nomad DX12. The NVIDIA GeForce RTX 4070 Ti SUPER AD102 scores 6269.5, and the Intel Arc B390 scores 1482. The delta is -76.4% from the Intel part's perspective, meaning the NVIDIA card is approximately 4.2 times faster in this workload.

That single result overshadows every other comparison. The NVIDIA card's nearest rivals in the database include the NVIDIA GeForce RTX 5070 Ti SUPER with an identical average score of 6270 and a delta of 0%, the NVIDIA Quadro K620 at 6282 (-0.2%), the AMD FirePro W600 at 6223 (+0.8%), and the AMD Radeon R7 M350 at 6327 (-0.9%). The Intel Arc B390's nearest rivals are all much lower: the NVIDIA GeForce GT 520MX at 1463 (+1.3%), the NVIDIA GeForce 800M at 1460 (+1.5%), the NVIDIA GeForce GT 625 OEM at 1446 (+2.5%), and the NVIDIA GeForce GT 710 at 1443 (+2.7%).

The percentiles tell the same story. The NVIDIA card sits at the 36th percentile among all GPUs, indicating it outperforms roughly two-thirds of the database. The Intel part sits at the 9th percentile, outperforming only a small fraction of entries.

Beyond the benchmark, the architectural numbers amplify the result. The NVIDIA card's 44.10 TFLOPS FP32 throughput versus the Intel part's 7.680 TFLOPS is a 5.7 times advantage. Its 250.6 GPixel/s pixel rate versus 60.00 GPixel/s is a 4.2 times advantage. Its 689.0 GTexel/s texture rate versus 120.0 GTexel/s is a 5.7 times advantage. Memory bandwidth of 672.3 GB/s versus system-dependent shared memory removes any doubt about sustained throughput.

The RT core count difference, 66 versus 12, matters for ray-traced workloads, though no dedicated ray tracing benchmark is recorded. The tensor core presence on the NVIDIA card, 264 of them, versus none listed on the Intel part, indicates a clear split in AI-accelerated features.

The verdict from the recorded data is unambiguous: the NVIDIA GeForce RTX 4070 Ti SUPER AD102 is the dominant performer in every measured dimension, while the Intel Arc B390 is the only option for integrated, low-power, portable graphics.
