Intel Arc B390 vs NVIDIA GeForce RTX 4070 Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct head-to-head comparison between the Intel Arc B390 and the NVIDIA GeForce RTX 4070: the 3DMark Steel Nomad DX12 test. In this benchmark, the NVIDIA GeForce RTX 4070 scores 3854, while the Intel Arc B390 scores 1482. The delta is -61.5%, meaning the Intel part trails by more than three-fifths of the NVIDIA card's result. This is a decisive margin in a modern DirectX 12 workload.

The gap places the Intel Arc B390 in a fundamentally different performance class. Its average benchmark score across all recorded tests is 1482, and it sits at the 9th percentile among all GPUs in the database. The RTX 4070, by contrast, posts an average benchmark score of 37648 and occupies the 81st percentile. That percentile spread, from the bottom decile to the upper fifth, underscores how far apart these two products are in raw throughput.

The RTX 4070 also shows its breadth in additional benchmark categories that the Arc B390 does not have recorded entries for. In Geekbench OpenCL, the RTX 4070 scores 154858, and in Geekbench Vulkan it reaches 174152. PassMark results for the RTX 4070 range from a low of 103 in DirectX 12 to a high of 320 in DirectX 9, with a G3D score of 26927 and a GPU compute score of 14720. The Intel Arc B390 has no comparable entries in these tests, so the comparison rests on the single shared 3DMark result.

The nearest rivals for the Arc B390, based on average score, are all much older or lower-tier NVIDIA parts. The GeForce GT 520MX averages 1463, a 1.3% delta. The GeForce 800M averages 1460, a 1.5% delta. The GeForce GT 625 OEM averages 1446, a 2.5% delta. The GeForce GT 710 averages 1443, a 2.7% delta. These deltas are small, all within 3 percentage points, indicating that the Arc B390 clusters with entry-level GPUs from a decade ago rather than with any modern discrete card.

The RTX 4070's nearest rivals, meanwhile, sit much closer to its own performance level. The NVIDIA Tesla P4 averages 37628, a 0.1% delta. The AMD Radeon RX Vega 56 averages 37507, a 0.4% delta. The NVIDIA GeForce RTX 4080 Mobile averages 38135, a -1.3% delta, meaning the RTX 4070 is actually slightly behind that mobile part. The AMD Radeon PRO W6400 averages 37157, a 1.3% delta. These tight deltas show the RTX 4070 competing with mid-range and upper-mid-range cards, not with the Intel integrated graphics class.

Where Each One Wins

The NVIDIA GeForce RTX 4070 wins in every measurable category where both have data. The 3DMark Steel Nomad DX12 result is the only direct comparison, and the RTX 4070 takes it by 2372 points. The RTX 4070 also holds substantial leads in its additional benchmark entries, which the Arc B390 does not appear in, such as Geekbench OpenCL (154858), Geekbench Vulkan (174152), and PassMark G3D (26927). Its PassMark GPU compute score of 14720 further confirms strength in compute-heavy workloads.

The Intel Arc B390 has no benchmark victories. Its single recorded score of 1482 places it among GPUs like the GeForce GT 710 and GeForce GT 520MX, which are far below the RTX 4070's performance tier. The Arc B390's only advantage is qualitative: it is an integrated graphics processor (IGP) with zero power connectors and no suggested PSU, meaning it draws power from the host system rather than requiring a dedicated power supply. That is not a benchmark win, but it changes the deployment context entirely.

For users who need raw rendering performance, the RTX 4070 is the only option with meaningful numbers. For systems where a discrete GPU is not feasible, the Arc B390 at least provides a baseline DirectX 12 Ultimate-capable output, but the data shows no scenario where it outperforms the NVIDIA card.

Specification Differences

The two GPUs differ in nearly every hardware specification. The Intel Arc B390 uses a base clock of 300 MHz and a boost clock of 2500 MHz. The NVIDIA GeForce RTX 4070 uses a base clock of 1920 MHz and a boost clock of 2475 MHz. Memory also diverges sharply: the Arc B390 uses system shared memory with a system dependent bandwidth, while the RTX 4070 has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s of bandwidth.

Compute resources differ by a wide margin. The Arc B390 has 1536 shading units, 48 texture mapping units, and 24 ROPs. The RTX 4070 has 5888 shading units, 184 TMUs, and 64 ROPs. Ray tracing cores differ as well: 12 on the Arc B390 versus 46 on the RTX 4070. The RTX 4070 also has 184 tensor cores, while the Arc B390 lists none.

Pixel and texture rates reflect the resource gap. The Arc B390 achieves 60.00 GPixel/s and 120.0 GTexel/s. The RTX 4070 achieves 158.4 GPixel/s and 455.4 GTexel/s. FP32 throughput is 7.680 TFLOPS for the Arc B390 versus 29.15 TFLOPS for the RTX 4070. FP16 differs in ratio: the Arc B390 offers 15.36 TFLOPS at a 2:1 rate, while the RTX 4070 offers 29.15 TFLOPS at a 1:1 rate.

Power and physical specifications are likewise distinct. The Arc B390 has a TDP of 80 W, uses an IGP slot width, and has no power connectors. The RTX 4070 has a TDP of 200 W, uses a dual-slot form factor, requires a single 16-pin power connector, and has a suggested PSU of 550 W. The RTX 4070 also has defined dimensions of 240 mm length, 110 mm height, and 40 mm width. The Arc B390 has no listed dimensions. Display outputs differ: the Arc B390 is portable device dependent, while the RTX 4070 offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Architecture Differences

The Intel Arc B390 is built on Intel's 3 nm process node, manufactured by Intel, using the Panther Lake chip with the Xe3-LPG architecture. It belongs to the Arc Graphics-M generation, which is oriented toward integrated graphics in mobile or compact systems. The transistor count and die size are listed as unknown, so no density comparison is possible.

The NVIDIA GeForce RTX 4070 uses the AD104 chip with the Ada Lovelace architecture, built on TSMC's 5 nm process node. It has 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². It belongs to the GeForce 40-series generation, with predecessors and successors in the GeForce 30 and GeForce 50 lines respectively.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. That is where the API compatibility ends. The Arc B390 has no tensor cores, while the RTX 4070 includes 184 of them, enabling features that the Intel part cannot accelerate in the same way. The RTX 4070's 46 RT cores versus the Arc B390's 12 represent a major difference in ray tracing throughput.

Memory architecture is the other major split. The Arc B390 relies on system shared memory, making its bandwidth dependent on the host platform's memory configuration. The RTX 4070 uses dedicated GDDR6X with a fixed 504.2 GB/s bandwidth, which is not subject to system-level contention.

The production status also differs: the Arc B390 is Active, while the RTX 4070 is End-of-life. The RTX 4070's release date of 2023-04-11 predates the Arc B390's release date of 2026-01-26 by nearly three years.

The Verdict

The data points to a straightforward conclusion: the NVIDIA GeForce RTX 4070 is in a far higher performance class than the Intel Arc B390. In the only shared benchmark, the RTX 4070 leads by 61.5%. Its average benchmark score of 37648 is over 25 times the Arc B390's average of 1482. The percentile ranking (81st versus 9th) confirms that the RTX 4070 competes with mid-range to upper-mid-range discrete GPUs, while the Arc B390 clusters with entry-level parts from an earlier era.

The RTX 4070 also offers dedicated memory, a wider bus, higher clock speeds, more shading units, more ray tracing cores, and tensor cores. Its 12 GB of GDDR6X with 504.2 GB/s of bandwidth removes the system memory dependency that limits the Arc B390. The RTX 4070's TDP of 200 W and dual-slot design assume a system with a 550 W PSU and a PCIe 4.0 x16 slot. The Arc B390, as an IGP with no power connectors, requires none of that infrastructure.

For a user with a desktop system capable of housing a discrete GPU, the RTX 4070 is the only choice supported by the recorded measurements. For a compact or integrated system where add-in cards are not possible, the Arc B390 provides a DirectX 12 Ultimate-capable output, but its performance level, as measured by the 3DMark Steel Nomad score, is comparable to GPUs like the GeForce GT 710 or GeForce GT 520MX. The RTX 4070, meanwhile, sits within 1.3% of the Tesla P4 and within 0.4% of the Radeon RX Vega 56, placing it in a completely different competitive bracket.

The launch MSRP of the RTX 4070 is 599 USD. That figure, combined with the benchmark data, indicates a product aimed at mainstream and enthusiast builds. The Arc B390 has no launch MSRP listed, consistent with its integrated nature. The verdict from the database is unambiguous: the RTX 4070 wins every measured category, and the Arc B390's only advantages are its active production status, lower power draw, and lack of external power requirements.
