Intel Arc B370 vs NVIDIA GeForce RTX 4070 GDDR6 Comparison

The Verdict

The recorded database positions the NVIDIA GeForce RTX 4070 GDDR6 as the dominant performer in this pairing. Its 3DMark Steel Nomad DX12 score of 4334.5 stands 72.7% above the Intel Arc B370's 1184, a gap that places the two in entirely different performance classes. The RTX 4070 GDDR6 sits at the 25th percentile among all GPUs in the database, while the Arc B370 lands at the 5th percentile. The Arc B370 is an integrated graphics solution with a 25 W power envelope, designed for portable devices, whereas the RTX 4070 GDDR6 is a dual-slot, 200 W discrete card with its own 12 GB memory pool. The data indicates the RTX 4070 GDDR6 is the only choice for demanding 3D workloads. The Arc B370's role is limited to light, integrated graphics scenarios where its minimal power draw and lack of a discrete power connector are the primary considerations. There is no benchmark result where the Arc B370 leads.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc B370 uses the Panther Lake chip built on Intel's 3 nm process, employing the Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation. The NVIDIA GeForce RTX 4070 GDDR6 uses the AD104 chip on TSMC's 5 nm process, built on the Ada Lovelace architecture, and belongs to the GeForce 40-series generation. The RTX 4070 GDDR6 has a transistor count of 35,800 million on a 294 mm² die, with a transistor density of 121.8M per mm², while the Arc B370's transistor count and die size are listed as unknown in the database.

The Arc B370 presents a compact integrated configuration: 1280 shading units, 40 texture mapping units, 20 raster output pipelines, and 10 ray tracing cores. It has no tensor cores listed. Its memory is system shared, with no dedicated VRAM, bus width, or bandwidth figures; memory bandwidth is listed as system dependent. The RTX 4070 GDDR6 delivers a much larger compute configuration: 5888 shading units, 184 TMUs, 64 ROPs, 46 ray tracing cores, and 184 tensor cores. It uses 12 GB of GDDR6 memory on a 192-bit bus, with 480.0 GB/s of bandwidth.

The Arc B370's clock behavior also differs: a base clock of 300 MHz and a boost clock of 2400 MHz, whereas the RTX 4070 GDDR6 runs at 1920 MHz base and 2475 MHz boost, with memory at 2500 MHz (20 Gbps effective). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Arc B370 is an IGP with no power connectors and no slot width beyond the integrated form factor, while the RTX 4070 GDDR6 is a dual-slot card requiring a 1x 16-pin connector and a suggested 550 W power supply. The RTX 4070 GDDR6's predecessor is GeForce 30, and its successor is GeForce 50; the Arc B370 has no listed predecessor or successor.

Head-to-Head Benchmarks

The only head-to-head benchmark recorded in the database is 3DMark Steel Nomad DX12. The NVIDIA GeForce RTX 4070 GDDR6 scores 4334.5, while the Intel Arc B370 scores 1184. The delta is -72.7% for the Arc B370, meaning the RTX 4070 GDDR6 outperforms it by that margin. This is the sole benchmark in the comparison, and the RTX 4070 GDDR6 wins it outright; the Arc B370 records zero wins across the head-to-head set.

The absolute difference is 3150.5 points, which is roughly 3.66 times the Arc B370's entire score. The RTX 4070 GDDR6's nearest rivals in the database, such as the Intel Iris Pro Graphics 5200 at 4360 (-0.6%) and the NVIDIA GeForce 930M at 4388 (-1.2%), show that its score sits within a narrow band of comparable results, though those rivals are far older mobile parts. The Arc B370's nearest rivals, including the ATI Mobility Radeon HD 5570 at 1186 (-0.2%) and the AMD Radeon HD 7650M at 1192 (-0.7%), indicate its performance level aligns with legacy discrete mobile GPUs from over a decade ago. The percentile ranking confirms this: 25th for the RTX 4070 GDDR6 versus 5th for the Arc B370.

Where Each One Wins

The NVIDIA GeForce RTX 4070 GDDR6 wins the only recorded benchmark, 3DMark Steel Nomad DX12, by 72.7%. Its pixel rate of 158.4 GPixel/s versus 48.00 GPixel/s, texture rate of 455.4 GTexel/s versus 96.00 GTexel/s, and FP32 throughput of 29.15 TFLOPS versus 6.144 TFLOPS all indicate a wide margin in raw rendering capacity. The RTX 4070 GDDR6's 46 ray tracing cores and 184 tensor cores, absent in the Arc B370's specification, give it a structural advantage in ray-traced and AI-accelerated workloads, although no direct benchmark for those features is recorded here.

The Intel Arc B370's wins are not in performance but in integration and power efficiency. Its 25 W TDP, no power connectors, and IGP form factor mean it operates entirely within a host device's existing power and thermal envelope. It has no memory of its own, relying on system shared memory, which eliminates the need for a discrete VRAM pool. Its release date of 2026-01-26 is later than the RTX 4070 GDDR6's 2024-08-19, and its production status is Active, whereas the RTX 4070 GDDR6 is End-of-life.

For workloads requiring maximum frame rates or complex 3D scenes, the benchmark data clearly favors the RTX 4070 GDDR6. For ultra-portable systems where discrete graphics are impossible, the Arc B370 is the only option that fits, but its performance ceiling is defined by the 1184 Steel Nomad score, which places it among legacy mobile GPUs from a much older era. The RTX 4070 GDDR6's nearest rivals in the database, such as the Intel Iris Pro Graphics 5200 and NVIDIA GeForce 930M, all score within a few percentage points of 4334.5, confirming its position as a mid-tier performer despite being end-of-life. The Arc B370's nearest rivals, the ATI Mobility Radeon HD 5570 and AMD Radeon HD 7650M, score near 1184, reinforcing that its integrated design targets basic graphics duties rather than high-end rendering.
