Intel Arc B390 vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The benchmark database contains only one recorded measurement for the Intel Arc B390: a 3DMark Steel Nomad DX12 score of 1482. The NVIDIA GeForce RTX 4070 AD103 has no benchmark entries in the database, so a direct head-to-head comparison of measured scores is not possible. What the data does provide is the Arc B390's position within the broader GPU landscape. Its score places it at the 9th percentile among all GPUs, which indicates that most other graphics cards in the database outperform it. The nearest rivals in the database are all NVIDIA entry-level parts from past generations: the GeForce GT 520MX with an average score of 1463 (1.3% behind), the GeForce 800M with 1460 (1.5% behind), the GeForce GT 625 OEM with 1446 (2.5% behind), and the GeForce GT 710 with 1443 (2.7% behind). These deltas are small, meaning the Arc B390 sits in a cluster of very low-performance GPUs. The RTX 4070 AD103 holds a 50th percentile ranking among all GPUs, but with an average benchmark score of zero and no rival data, the database cannot quantify the gap between these two cards. The absence of a recorded score for the RTX 4070 AD103 means any numerical comparison would be speculative. The data confirms the Arc B390 is an integrated graphics solution, while the RTX 4070 AD103 is a discrete add-in board, and the benchmark results reflect that fundamental positioning.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The Intel Arc B390 is built on the Xe3-LPG architecture and uses the Panther Lake chip, belonging to the Arc Graphics-M (Panther Lake) generation. It is fabricated on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 4070 AD103 uses the Ada Lovelace architecture with the AD103 chip, part of the GeForce 40 generation, and is manufactured on a 5 nm process at TSMC. The transistor counts differ substantially: the RTX 4070 AD103 packs 45,900 million transistors on a 379 mm² die, giving a transistor density of 121.1 million per square millimeter. The Arc B390's transistor count and die size are listed as unknown, so no density figure is available for comparison.

The compute pipelines reflect the architectural gap. The Arc B390 has 1536 shading units, 48 texture mapping units, 24 raster output units, and 12 ray tracing cores. The RTX 4070 AD103 has 5888 shading units, 184 TMUs, 64 ROPs, and 46 RT cores. The NVIDIA part also includes 184 tensor cores, a feature class that the Intel entry does not list. Clock behavior differs as well: the Arc B390 runs at a 300 MHz base clock and boosts to 2500 MHz, while the RTX 4070 AD103 has a 1920 MHz base clock and a 2475 MHz boost. The Intel card's lower base clock but higher boost suggests a wider dynamic range, though the NVIDIA card's base clock is far higher.

Memory architecture is another fundamental split. The Arc B390 uses system-shared memory, with its bandwidth dependent on the host system. The RTX 4070 AD103 uses dedicated 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s. The memory clock is 1313 MHz, described as 21 Gbps effective. The Arc B390's rendering rates are 60.00 GPixel/s pixel fill and 120.0 GTexel/s texture fill, while the RTX 4070 AD103 achieves 158.4 GPixel/s and 455.4 GTexel/s respectively. Floating-point throughput shows a similar ratio: the Arc B390 delivers 7.680 TFLOPS FP32 and 15.36 TFLOPS FP16 (with a 2:1 ratio), whereas the RTX 4070 AD103 delivers 29.15 TFLOPS FP32 and 29.15 TFLOPS FP16 (1:1 ratio). The API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The two cards differ across nearly every measurable specification. The Intel Arc B390 has a TDP of 80 W, while the NVIDIA GeForce RTX 4070 AD103 has a TDP of 200 W. The Arc B390 is an IGP with no power connectors and no suggested PSU, whereas the RTX 4070 AD103 is a dual-slot card requiring a single 16-pin connector and a 550 W suggested PSU. The bus interface for the Intel part is IGP, while the NVIDIA part uses PCIe 4.0 x16.

Physical dimensions are only recorded for the NVIDIA card: 240 mm (9.4 inches) in length, 110 mm (4.3 inches) in height, and 40 mm (1.6 inches) in width. The Intel card's dimensions are not listed.

Process technology differs: 3 nm for Intel versus 5 nm for TSMC. The RTX 4070 AD103 has a known transistor count of 45,900 million and a die size of 379 mm², while the Arc B390 has unknown values for both. The memory subsystem is entirely different: system-shared for the Intel part versus 12 GB GDDR6X with a 192-bit bus and 504.2 GB/s bandwidth for the NVIDIA part. The core counts are not close: 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores for Intel versus 5888 shading units, 184 TMUs, 64 ROPs, and 46 RT cores for NVIDIA. The NVIDIA card also has 184 tensor cores, a feature absent from the Intel specifications. Production status differs as well: the Arc B390 is Active with a release date of January 26, 2026, while the RTX 4070 AD103 is End-of-life with a release date of February 29, 2024. The NVIDIA card's predecessor is the GeForce 30 series and its successor is the GeForce 50 series; the Intel card has no predecessor or successor listed. The RTX 4070 AD103 has a launch MSRP of 599 USD; the Arc B390 has no launch MSRP recorded.

The Verdict

The recorded data points to a clear separation in class and capability. The Intel Arc B390 is an integrated GPU with an 80 W TDP, system-shared memory, and a benchmark score of 1482 that places it at the 9th percentile of all GPUs. Its nearest rivals are all low-end NVIDIA parts from previous generations, and it leads them by margins of only 1.3% to 2.7%. This is entry-level integrated graphics performance by any measure. The NVIDIA GeForce RTX 4070 AD103 is a discrete, dual-slot card with a 200 W TDP, 12 GB of dedicated GDDR6X memory, 504.2 GB/s of bandwidth, and a 50th percentile ranking among all GPUs. Its transistor count of 45,900 million, 5888 shading units, and 29.15 TFLOPS FP32 throughput indicate a design aimed at high-end gaming and compute workloads. The database does not contain a direct benchmark comparison between the two, so a precise performance delta cannot be stated. However, the specification differences are so large across every relevant metric, from shading units to memory bandwidth to TDP, that the data supports treating them as separate product categories. The user choosing between them would base the decision on the host platform: the Arc B390 is an integrated solution for portable devices, while the RTX 4070 AD103 is a standalone expansion card for desktop systems. The RTX 4070 AD103 is end-of-life with a successor in the GeForce 50 series, whereas the Arc B390 is currently active in production.

Where Each One Wins

The Intel Arc B390 wins in the context of integrated, low-power computing. Its 80 W TDP and lack of external power connectors make it suitable for portable devices where dedicated graphics are not an option. Its system-shared memory means it relies on the host system's RAM, which simplifies the hardware design. The benchmark data shows it outperforming the GeForce GT 520MX, GeForce 800M, GeForce GT 625 OEM, and GeForce GT 710 by slim margins, so within that class of legacy entry-level GPUs, it holds a small lead. Its 3 nm process node is the more advanced manufacturing technology between the two cards, and its base clock of 300 MHz with a boost to 2500 MHz shows a wide frequency range for an integrated part. The Arc B390 is also an active product with a 2026 release date, so it represents the current generation of Intel's integrated graphics.

The NVIDIA GeForce RTX 4070 AD103 wins in every performance-oriented specification recorded. Its 5888 shading units, 184 TMUs, and 64 ROPs dwarf the Intel part's counts. The 46 RT cores and 184 tensor cores give it hardware acceleration for ray tracing and AI workloads that the Arc B390 does not list. Its 12 GB of GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth is a dedicated, high-speed memory subsystem, as opposed to the system-shared approach of the Intel card. The pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are more than double the Intel card's rates. The FP32 throughput of 29.15 TFLOPS is approximately 3.8 times the Arc B390's 7.680 TFLOPS. The RTX 4070 AD103 also provides 1x HDMI 2.1 and 3x DisplayPort 1.4a outputs for multi-display setups, while the Intel part's outputs are dependent on the portable device. The 50th percentile ranking among all GPUs places the NVIDIA card at the midpoint of the database's performance distribution, a far stronger position than the Arc B390's 9th percentile. The launch MSRP of 599 USD for the RTX 4070 AD103 reflects its discrete, high-end positioning, though the Arc B390 has no recorded launch price. For users with a desktop platform and a need for dedicated graphics performance, the RTX 4070 AD103 is the only option between the two that the data supports. For users on portable devices with integrated graphics, the Arc B390 provides a measurable, though modest, level of 3D performance.
