Architecture Differences

The Intel Arc B370 and NVIDIA GeForce RTX 4070 come from fundamentally different design philosophies. The Arc B370 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel's foundry. The RTX 4070 uses the AD104 chip with Ada Lovelace architecture, built on a 5 nm process at TSMC. The process node difference is significant: the Arc B370's 3 nm node is smaller, though the RTX 4070's larger 5 nm node allows for a substantial transistor count of 35,800 million and a die size of 294 mm². The Arc B370 lists its transistor count and die size as unknown in the database.

The compute configurations diverge sharply. The Arc B370 has 1280 shading units, 40 texture mapping units, and 20 ROPs. The RTX 4070 has 5888 shading units, 184 TMUs, and 64 ROPs. This means the RTX 4070 has roughly 4.6 times the shading units, 4.6 times the TMUs, and 3.2 times the ROPs. Ray tracing hardware also differs: the Arc B370 has 10 RT cores, while the RTX 4070 has 46. The RTX 4070 additionally includes 184 tensor cores, a feature not present in the Arc B370's listed specifications.

Clock speeds and power characteristics reveal different design targets. The Arc B370 runs at a base clock of 300 MHz and a boost clock of 2400 MHz, with a TDP of 25 W. The RTX 4070 operates at a base clock of 1920 MHz and a boost clock of 2475 MHz, with a TDP of 200 W. The Arc B370's lower power draw is consistent with its IGP (integrated graphics processor) slot width, while the RTX 4070 is a dual-slot discrete card requiring a 16-pin power connector and a suggested 550 W PSU.

Memory architecture is a major differentiator. The Arc B370 uses system shared memory with a system-dependent bandwidth, meaning it has no dedicated VRAM. The RTX 4070 has 12 GB of GDDR6X memory on a 192-bit bus with 504.2 GB/s of bandwidth. The RTX 4070's memory clock is listed at 1313 MHz, which translates to 21 Gbps effective. The Arc B370's memory subsystem is entirely dependent on the host system, while the RTX 4070 has a self-contained, high-bandwidth memory pool.

The bus interface also differs. The Arc B370 uses an IGP bus interface, while the RTX 4070 uses PCIe 4.0 x16. Display outputs follow the same pattern: the Arc B370's outputs are portable device dependent, while the RTX 4070 has 1x HDMI 2.1 and 3x DisplayPort 1.4a. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The production status marks the Arc B370 as Active, while the RTX 4070 is End-of-life. The RTX 4070 has a predecessor in the GeForce 30 series and a successor in the GeForce 50 series. The Arc B370 lists no predecessor or successor in the database.

Head-to-Head Benchmarks

The database contains a single head-to-head benchmark between these two GPUs: 3DMark Steel Nomad DX12. In this test, the Intel Arc B370 scores 1184, and the NVIDIA GeForce RTX 4070 scores 3854. The delta percentage is -69.3%, meaning the Arc B370 trails the RTX 4070 by 69.3% of the RTX 4070's score. This is a decisive win for the RTX 4070, with the Arc B370 achieving roughly 30.7% of the RTX 4070's performance in this workload.

The RTX 4070's nearest rivals in the database provide context for its score. The NVIDIA Tesla P4 scores 37628, a 0.1% difference from the RTX 4070's average. The AMD Radeon RX Vega 56 scores 37507, a 0.4% difference. The NVIDIA GeForce RTX 4080 Mobile scores 38135, which is 1.3% higher than the RTX 4070. The AMD Radeon PRO W6400 scores 37157, 1.3% lower. The RTX 4070's average benchmark score of 37648 sits within a narrow band of these rivals, indicating consistent performance around that level.

For the Arc B370, the nearest rivals cluster around its 1184 score. The ATI Mobility Radeon HD 5570 scores 1186, a 0.2% difference. The ATI Radeon HD 5770 scores 1190, a 0.5% difference. The AMD Radeon HD 7650M scores 1192, a 0.7% difference. The AMD FirePro M2000 scores 1168, 1.4% lower than the Arc B370. This places the Arc B370 in a performance tier that is roughly three decades older in terms of GPU generations, based on the rival names in the database.

The RTX 4070 also has additional benchmark results beyond the Steel Nomad test. Its Geekbench OpenCL score is 154858, and its Geekbench Vulkan score is 174152. Passmark results include DirectX 10 at 139, DirectX 11 at 244, DirectX 12 at 103, DirectX 9 at 320, G2D at 1164, G3D at 26927, and GPU compute at 14720. The Arc B370 has only the single Steel Nomad score in its benchmark record.

The Verdict

The data clearly separates these two GPUs into distinct performance classes. The NVIDIA GeForce RTX 4070 outscores the Intel Arc B370 by 69.3% in the only shared benchmark, and its average benchmark score of 37648 is over 30 times the Arc B370's 1184. The RTX 4070's 81st percentile ranking versus the Arc B370's 5th percentile confirms this gap is not an artifact of a single test but reflects the GPU's position across the database's GPU population.

The RTX 4070 is the appropriate choice for workloads requiring high compute throughput, dedicated memory bandwidth, and ray tracing capability. Its 12 GB of GDDR6X memory with 504.2 GB/s bandwidth provides a self-contained memory pool, while the Arc B370 depends entirely on system shared memory. The RTX 4070's 5888 shading units, 184 TMUs, and 46 RT cores make it substantially more capable in both rasterization and ray-traced workloads.

The Intel Arc B370, with its 25 W TDP and IGP form factor, targets a fundamentally different use case. Its 1280 shading units and 10 RT cores are modest by comparison, but its power envelope is 8 times lower than the RTX 4070's 200 W. The Arc B370's active production status suggests it is intended for portable or integrated devices, where the RTX 4070's dual-slot, 240 mm length, and 16-pin power connector would not fit.

The RTX 4070's end-of-life status and its position between the GeForce 30 and GeForce 50 series place it as a prior-generation discrete GPU. The Arc B370, released later and still active, represents a current integrated solution. The data does not indicate any scenario where the Arc B370 outperforms the RTX 4070 in compute or graphics benchmarks. The RTX 4070 wins the sole head-to-head test, and its broader benchmark suite shows consistent strength across DirectX versions and compute workloads.

Where Each One Wins

The NVIDIA GeForce RTX 4070 wins in every measurable performance category from the database. The single head-to-head benchmark, 3DMark Steel Nomad DX12, shows the RTX 4070 ahead by 69.3%. The RTX 4070's additional benchmarks demonstrate strength across multiple API generations: its Passmark DirectX 9 score of 320, DirectX 10 score of 139, DirectX 11 score of 244, and DirectX 12 score of 103 all indicate functional performance across older and newer graphics APIs. Its Geekbench OpenCL score of 154858 and Vulkan score of 174152 show strong compute and cross-platform graphics capability.

The RTX 4070's pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are substantially higher than the Arc B370's 48.00 GPixel/s and 96.00 GTexel/s. Its FP32 throughput of 29.15 TFLOPS is roughly 4.7 times the Arc B370's 6.144 TFLOPS. Memory bandwidth favors the RTX 4070 with 504.2 GB/s versus the Arc B370's system-dependent bandwidth, which has no fixed figure in the database.

The Intel Arc B370's wins are not performance-based but form-factor and power-based. Its 25 W TDP is 8 times lower than the RTX 4070's 200 W. Its IGP slot width and lack of power connectors indicate it requires no external power. The Arc B370's smaller process node of 3 nm versus 5 nm suggests a more modern manufacturing approach, though this does not translate into performance advantages in the recorded data. The Arc B370's active production status and later release date indicate it is the more current product, but the database shows no benchmark where it beats the RTX 4070.

For users prioritizing compute performance, ray tracing capability, or dedicated VRAM, the RTX 4070 is the clear choice based on the data. For users constrained by power consumption or physical space, the Arc B370's integrated design offers a low-power alternative, though the performance trade-off is severe: 69.3% behind in the shared benchmark and a 5th percentile ranking versus the RTX 4070's 81st.
