Intel Arc B390 vs NVIDIA GeForce RTX 4070 SUPER Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark between the two GPUs is the 3DMark Steel Nomad DX12 test. The recorded data shows the NVIDIA GeForce RTX 4070 SUPER scoring 4627, while the Intel Arc B390 scores 1482. This translates to the RTX 4070 SUPER outperforming the Intel part by 68 percent. The delta is massive, and it places the two products in entirely different performance strata.

Looking at the broader database context, the Intel Arc B390 sits at the 9th percentile of all GPUs, with an average benchmark score of 1482. Its nearest rivals include the NVIDIA GeForce GT 520MX (1463, 1.3 percent ahead), the NVIDIA GeForce 800M (1460, 1.5 percent ahead), the NVIDIA GeForce GT 625 OEM (1446, 2.5 percent ahead), and the NVIDIA GeForce GT 710 (1443, 2.7 percent ahead). These are all entry-level, legacy-class parts. The Intel GPU is barely ahead of them, which indicates its raw 3D performance is extremely limited in this specific DX12 workload.

The NVIDIA GeForce RTX 4070 SUPER, by contrast, records an average benchmark score of 43223 across multiple tests, placing it at the 83rd percentile. Its nearest rivals are all high-end or enthusiast-class products: the NVIDIA Quadro M6000 24 GB (43262, 0.1 percent ahead), the NVIDIA GeForce RTX 5050 Mobile (43268, 0.1 percent ahead), the NVIDIA Quadro M6000 (43301, 0.2 percent ahead), and the NVIDIA GeForce RTX 4090 Mobile (43667, 1 percent ahead). The RTX 4070 SUPER is essentially tied with these, all within a 1 percent band. This shows that the NVIDIA card clusters with some of the most powerful GPUs in the database, while the Intel part clusters with the weakest.

The head-to-head delta of -68 percent for the Intel Arc B390 is not a marginal gap; it is a categorical separation. In a single benchmark, the NVIDIA card delivers more than three times the raw score. No other comparable test data exists between these two products, so the analysis rests on this one metric, but the result is unambiguous.

Architecture Differences

The Intel Arc B390 uses the Xe3-LPG architecture on a 3 nm process node, fabricated by Intel. The chip is designated Panther Lake, and it belongs to the Arc Graphics-M generation. The GPU is an integrated part (IGP), meaning it shares system memory and has no dedicated video memory. Its base clock is 300 MHz, boosting to 2500 MHz. The memory clock is listed as "System Shared," and bandwidth is "System Dependent," which means performance scales with the host system's memory configuration.

The NVIDIA GeForce RTX 4070 SUPER uses the Ada Lovelace architecture on a 5 nm process node, fabricated by TSMC. The chip is AD104, part of the GeForce 40-series. It has 35,800 million transistors on a 294 mm² die, giving a transistor density of 121.8M per mm². The Intel part's transistor count and die size are unknown, so no direct comparison is possible. The NVIDIA card has a base clock of 1980 MHz and a boost clock of 2475 MHz. Its memory runs at 1313 MHz with 21 Gbps effective speed.

The RTX 4070 SUPER has 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The Intel Arc B390 relies on system shared memory, with no dedicated VRAM. This is a fundamental architectural difference: one is a discrete expansion card with its own high-speed memory, the other is an integrated GPU sharing bandwidth with the CPU and system.

The NVIDIA card uses a 16-pin power connector and requires a 550 W power supply, consuming 220 W. The Intel IGP draws 80 W and uses no power connectors, as it is integrated into the host processor. The Intel card is dual-slot (IGP form factor), while the NVIDIA card is dual-slot with dimensions of 267 mm length, 112 mm height, and 42 mm width.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card has 224 tensor cores and 56 RT cores, while the Intel part has 12 RT cores and no tensor core data. The shading unit counts differ massively: 7168 for NVIDIA versus 1536 for Intel. Texture mapping units are 224 versus 48, and ROPs are 80 versus 24.

The Verdict

The data is clear: the NVIDIA GeForce RTX 4070 SUPER is a discrete, high-performance GPU intended for demanding 3D workloads, while the Intel Arc B390 is an integrated solution with minimal 3D capability. The 68 percent deficit in the Steel Nomad test, combined with the percentile gap (83rd versus 9th), shows these products do not compete in the same segment.

The RTX 4070 SUPER delivers 35.48 TFLOPS of FP32 performance, 35.48 TFLOPS of FP16 (1:1), a pixel rate of 198.0 GPixel/s, and a texture rate of 554.4 GTexel/s. The Intel Arc B390 delivers 7.680 TFLOPS FP32, 15.36 TFLOPS FP16 (2:1), 60.00 GPixel/s pixel rate, and 120.0 GTexel/s texture rate. Every compute metric favors NVIDIA by a wide margin.

The NVIDIA card is end-of-life with a successor (GeForce 50) already in the database, while the Intel part is active. However, production status does not change the performance reality. For any application requiring substantial graphics throughput, the RTX 4070 SUPER is the only viable choice based on the recorded measurements. The Intel Arc B390 is suitable for basic display output and light workloads, but the benchmark data does not support its use in performance-sensitive scenarios.

Where Each One Wins

The NVIDIA GeForce RTX 4070 SUPER wins in every measurable performance category. It is ahead in the 3DMark Steel Nomad DX12 test by 68 percent. It has higher pixel rate (198.0 versus 60.00 GPixel/s), higher texture rate (554.4 versus 120.0 GTexel/s), and higher FP32 throughput (35.48 versus 7.680 TFLOPS). It has more shading units (7168 versus 1536), more TMUs (224 versus 48), more ROPs (80 versus 24), more RT cores (56 versus 12), and more tensor cores (224 versus none). It has dedicated GDDR6X memory with 504.2 GB/s bandwidth, while the Intel part depends on system memory.

The Intel Arc B390 wins in power efficiency and physical footprint. It consumes 80 W versus 220 W, uses no power connectors, and is an integrated part with no expansion slot requirements. Its boost clock is slightly higher (2500 MHz versus 2475 MHz), and it is manufactured on a smaller 3 nm node versus 5 nm. It is also currently active in production, while the NVIDIA card is end-of-life.

For a desktop workstation or gaming rig with a discrete PCIe slot available, the RTX 4070 SUPER is the clear choice based on benchmark data. For an ultra-portable or low-power integrated system where the 3D workload is minimal, the Arc B390's 80 W TDP and lack of external power requirements could be advantageous. However, the recorded benchmarks show no scenario where the Intel part approaches the NVIDIA card's performance. The data indicates that the RTX 4070 SUPER is for users who need high frame rates and compute throughput, while the Arc B390 is for basic graphics output in a power-constrained environment.
