Intel Arc B390 vs NVIDIA GeForce RTX 4070 Ti Comparison

The Verdict

The recorded data presents a stark comparison between these two graphics solutions. The NVIDIA GeForce RTX 4070 Ti holds a commanding lead in every measurable benchmark category, with the Intel Arc B390 occupying a fundamentally different performance tier. In the single head-to-head benchmark available, 3DMark Steel Nomad DX12, the RTX 4070 Ti scores 5024 against the Arc B390's 1482, a delta of 70.5% in favor of NVIDIA. The Arc B390 sits at the 9th percentile among all GPUs in the database, while the RTX 4070 Ti reaches the 84th percentile. The Intel part is an integrated graphics processor (IGP) with a 80 W TDP, designed for portable devices, whereas the RTX 4070 Ti is a dual-slot discrete card with a 285 W TDP and a 600 W suggested PSU. The data indicates these products serve entirely different purposes: the Arc B390 is for lightweight, power-constrained portable systems, while the RTX 4070 Ti is for high-performance desktop gaming and compute workloads. The RTX 4070 Ti's nearest rivals in the database include the NVIDIA GeForce RTX 5090 Mobile (0.8% lower score), AMD Radeon Pro 5500 XT (1.3% lower), and RTX A6000 (1.6% lower), placing it in the upper echelon of recorded GPUs. The Arc B390's nearest rivals are legacy entry-level parts like the GeForce GT 520MX (1.3% higher), GeForce 800M (1.5% higher), and GT 710 (2.7% higher), which confirms its position at the bottom of the performance spectrum.

Architecture Differences

The Intel Arc B390 uses the Xe3-LPG architecture, built on Intel's 3 nm process node, with the chip codenamed Panther Lake. It belongs to the Arc Graphics-M generation, indicating a mobile-focused design. The NVIDIA GeForce RTX 4070 Ti uses the Ada Lovelace architecture on TSMC's 5 nm node, with the AD104 chip and the GeForce 40-series branding. The process node difference is notable: 3 nm versus 5 nm, though the RTX 4070 Ti's larger die (294 mm²) and transistor count (35,800 million) dwarf the Arc B390's unspecified die size and transistor count, which the database records as unknown. The RTX 4070 Ti has a transistor density of 121.8M per mm². The Arc B390 integrates 1536 shading units, 48 texture mapping units, 24 render output units, and 12 ray tracing cores. The RTX 4070 Ti packs 7680 shading units, 240 TMUs, 80 ROPs, 60 RT cores, and 240 tensor cores. The shader count alone is a 5x difference in favor of NVIDIA. The Arc B390 has no tensor cores listed, while the RTX 4070 Ti includes dedicated tensor hardware. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists despite the massive hardware gap. The Arc B390 uses system-shared memory with system-dependent bandwidth, while the RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s of dedicated bandwidth. Clock behavior differs as well: the Arc B390 boosts to 2500 MHz from a 300 MHz base, whereas the RTX 4070 Ti runs at 2310 MHz base and 2610 MHz boost. The Intel part's memory clock is listed as system shared, while the NVIDIA card runs memory at 1313 MHz with 21 Gbps effective speed.

Where Each One Wins

The benchmark results show no scenario where the Intel Arc B390 outperforms the RTX 4070 Ti. The only head-to-head test, 3DMark Steel Nomad DX12, records a 70.5% victory for NVIDIA. The Arc B390's average benchmark score is 1482, derived solely from that single test, while the RTX 4070 Ti's average score across 10 recorded benchmarks is 44795. The RTX 4070 Ti wins in every category where data exists. For synthetic DX12 gaming workloads, the NVIDIA part delivers 5024 points versus 1482, which indicates roughly 3.4 times the raw performance. The RTX 4070 Ti also shows strength in compute-oriented tests: Geekbench OpenCL scores 176953, Geekbench Vulkan scores 213808, PassMark GPU Compute scores 18396, and PassMark G3D scores 31624. The Arc B390 has no recorded scores for those tests, so the data cannot quantify its compute performance, but the FP32 throughput figures tell the story: the RTX 4070 Ti delivers 40.09 TFLOPS compared to 7.680 TFLOPS for the Arc B390, a 5.2x gap. Pixel fill rate favors NVIDIA at 208.8 GPixel/s versus 60.00 GPixel/s, and texture rate favors NVIDIA at 626.4 GTexel/s versus 120.0 GTexel/s. The Arc B390's FP16 rate of 15.36 TFLOPS (2:1 ratio) does exceed its own FP32 rate, but the RTX 4070 Ti's FP16 matches its FP32 at 40.09 TFLOPS (1:1 ratio). The Arc B390 wins only in power efficiency, where its 80 W TDP is dramatically lower than the 285 W TDP of the RTX 4070 Ti, and in physical footprint, being an integrated solution with no power connectors and a portable-device-dependent display output.

Head-to-Head Benchmarks

The database contains exactly one direct comparison test between these two GPUs: 3DMark Steel Nomad DX12. In that test, the NVIDIA GeForce RTX 4070 Ti scores 5024 points against the Intel Arc B390's 1482 points. The delta percentage is 70.5%, meaning the RTX 4070 Ti delivers more than three times the performance of the Arc B390 in this DX12 workload. The Arc B390's score of 1482 places it just above the GeForce GT 520MX (1463) and GeForce 800M (1460), but below the GT 625 OEM (1446 is lower, so the Arc B390 beats it by 2.5%). The RTX 4070 Ti's score of 5024 aligns closely with its nearest rivals: RTX 5090 Mobile scores 45152 on average across its benchmark suite, which is 0.8% higher than the RTX 4070 Ti's average of 44795, and the Radeon Pro 5500 XT averages 45384, 1.3% higher. The RTX 4070 Ti's additional benchmark results show consistency across different test types: Geekbench OpenCL at 176953, Geekbench Vulkan at 213808, PassMark G3D at 31624, and PassMark GPU Compute at 18396. The PassMark DX9 score of 352 and DX11 score of 288 indicate strong legacy API performance, while DX12 scores 116 and DX10 scores 187. The Arc B390 has no recorded benchmarks beyond the single Steel Nomad test, so the database offers no further direct comparison points. Pixel rate data reinforces the gap: NVIDIA's 208.8 GPixel/s versus Intel's 60.00 GPixel/s, a 3.48x difference. Texture rate shows NVIDIA at 626.4 GTexel/s versus Intel's 120.0 GTexel/s, a 5.22x difference. FP32 throughput shows NVIDIA at 40.09 TFLOPS versus Intel's 7.680 TFLOPS. The RTX 4070 Ti wins the sole head-to-head benchmark with a 70.5% margin, and all supplementary performance metrics in the database point the same direction.
