Where Each One Wins

The RTX 4070 dominates in raw computational benchmarks. Its FP32 throughput of 29.15 TFLOPS exceeds the Arc Pro B70's 22.94 TFLOPS by a significant margin, representing a 27% advantage in shader performance. The RTX 4070 also has more shading units, 5888 versus 4096, and more RT cores, 46 versus 32, which positions it favorably for real-time graphics workloads that rely on ray tracing and traditional rasterization.

The Arc Pro B70 wins decisively in memory capacity and bandwidth. With 32 GB of memory versus 12 GB, the Intel card offers over 2.6 times the capacity, making it suitable for large datasets, high-resolution textures, and compute workloads that exceed the VRAM limits of the RTX 4070. Its bandwidth advantage, 608.0 GB/s versus 504.2 GB/s, further supports memory-intensive tasks. The Arc Pro B70 also has a higher pixel rate at 358.4 GPixel/s versus 158.4 GPixel/s, and a higher texture rate at 716.8 GTexel/s versus 455.4 GTexel/s, indicating stronger fill-rate capabilities for certain rendering scenarios.

For interface connectivity, the Arc Pro B70 uses PCIe 5.0 x16, while the RTX 4070 uses PCIe 4.0 x16, giving the Intel card double the theoretical bandwidth to the host system. The Arc Pro B70 also supports DisplayPort 2.1, a newer standard than the RTX 4070's DisplayPort 1.4a, enabling higher display refresh rates and resolutions where compatible monitors are used.

The RTX 4070 has a clear efficiency advantage based on recorded data. Its TDP of 200 W produces 29.15 TFLOPS of FP32, yielding roughly 146 TFLOPS per watt, while the Arc Pro B70's 230 W TDP produces 22.94 TFLOPS, yielding roughly 100 TFLOPS per watt. The NVIDIA card achieves higher performance while drawing less power, a meaningful distinction for system builders with power constraints.

Architecture Differences

The Intel Arc Pro B70 uses the Xe2-HPG architecture, which is the second generation of Intel's high-performance gaming-oriented GPU design, built on the BMG-G31 chip. This architecture is part of the Battlemage Pro Series, indicating a professional-grade variant of Intel's consumer-focused Battlemage line. The Xe2-HPG design emphasizes scalable execution units and dedicated ray tracing hardware, with 32 RT cores integrated into the chip.

The NVIDIA GeForce RTX 4070 uses the Ada Lovelace architecture, built on the AD104 chip. Ada Lovelace introduces a significantly different execution model, with 5888 shading units and 184 tensor cores alongside 46 RT cores. The tensor cores are dedicated to AI and deep learning workloads, providing hardware acceleration for features like DLSS that the Intel architecture lacks entirely, as the Arc Pro B70 has no tensor core equivalent in its specification.

Transistor counts reveal a stark difference in design philosophy. The RTX 4070 packs 35,800 million transistors into a 294 mm² die, achieving a transistor density of 121.8M per mm². The Arc Pro B70 has an unknown transistor count but uses a larger die at 368 mm², which suggests a less dense layout that may prioritize thermals and manufacturability over packing the maximum number of transistors into a small area. Both chips are fabricated on TSMC's 5 nm process, so the density difference comes from architectural choices rather than manufacturing technology.

Memory architecture differs substantially. The Arc Pro B70 uses GDDR6 memory, which is a mature and widely available memory type, while the RTX 4070 uses GDDR6X, a higher-bandwidth variant. The Intel card compensates with a wider 256-bit bus and larger capacity, whereas the NVIDIA card relies on faster memory signaling across a narrower 192-bit bus. The effective memory clock for the Arc Pro B70 is 19 Gbps, while the RTX 4070 runs at 21 Gbps effective, but the wider bus on the Intel card results in higher overall bandwidth.

The API support is identical for both cards: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. This means both cards can run the same modern graphics APIs, but the underlying hardware implementations differ, with NVIDIA's tensor cores enabling proprietary features that Intel cannot match without equivalent hardware.

Specification Differences

The two cards differ across nearly every major specification category in the database. The Arc Pro B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz, while the RTX 4070 has a base clock of 1920 MHz and a boost clock of 2475 MHz. The Intel card operates at higher clock speeds, which helps offset its lower shader count in some workloads.

Shading units favor NVIDIA at 5888 versus 4096, but the Intel card has more texture mapping units at 256 versus 184 and more render output units at 128 versus 64. This configuration gives the Arc Pro B70 a 2x advantage in pixel rate and a 1.6x advantage in texture rate, indicating that the Intel card is designed for fill-rate-heavy workloads such as high-resolution rendering.

The RTX 4070 has 184 tensor cores and 46 RT cores, while the Arc Pro B70 has 32 RT cores and no tensor cores. This makes the NVIDIA card substantially more capable for AI-accelerated tasks and ray tracing, as it has more dedicated hardware for both functions. The FP16 performance of the RTX 4070 is rated at 29.15 TFLOPS with a 1:1 ratio, meaning it processes FP16 at the same rate as FP32, while the Arc Pro B70 achieves 45.88 TFLOPS at a 2:1 ratio, doubling its FP16 throughput relative to FP32.

Physical dimensions are similar but not identical. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width, while the RTX 4070 measures 240 mm in length, 110 mm in height, and 40 mm in width. Both are dual-slot cards, but the Intel card is 27 mm longer. The power connectors differ, with the Arc Pro B70 using a traditional 8-pin connector and the RTX 4070 using a 16-pin connector, which may require adapter cables for older power supplies.

The bus interface also differs, with the Arc Pro B70 supporting PCIe 5.0 x16 and the RTX 4070 supporting PCIe 4.0 x16. This gives the Intel card a potential bandwidth advantage for data transfer between the GPU and CPU, particularly in professional workflows that move large datasets. Display outputs favor the Intel card with DisplayPort 2.1 support, while the RTX 4070 is limited to DisplayPort 1.4a.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the Arc Pro B70, meaning its measured performance is entirely absent from the records. The RTX 4070, however, has a full suite of benchmark scores. In 3DMark Steel Nomad DX12, the RTX 4070 scores 3854 points, which represents a modern DirectX 12 workload focused on rasterization and compute. Geekbench scores for the RTX 4070 are 154858 in OpenCL and 174152 in Vulkan, showing strong performance in both general-purpose compute and graphics workloads.

PassMark benchmark results for the RTX 4070 show a G3D score of 26927, which aggregates DirectX 9 through DirectX 12 performance. The individual PassMark API scores are 320 for DirectX 9, 244 for DirectX 11, 139 for DirectX 10, and 103 for DirectX 12, indicating that the card performs best in legacy DirectX 9 workloads and relatively weaker in newer API tests within that specific benchmark suite. The PassMark GPU Compute score is 14720, and the G2D score is 1164.

The RTX 4070 achieves an average benchmark score of 37648 across all recorded tests, placing it at the 81st percentile among all GPUs. Its nearest rivals in the database are the NVIDIA Tesla P4 with an average score of 37628 and a delta of 0.1%, the AMD Radeon RX Vega 56 with 37507 and a delta of 0.4%, the NVIDIA GeForce RTX 4080 Mobile with 38135 and a delta of -1.3%, and the AMD Radeon PRO W6400 with 37157 and a delta of 1.3%. These deltas show that the RTX 4070 essentially matches the Tesla P4 and RX Vega 56, while trailing the RTX 4080 Mobile by 1.3% and leading the PRO W6400 by 1.3%.

Since the Arc Pro B70 has no benchmark scores, its 50th percentile ranking appears to be a placeholder value rather than a measured result. The RTX 4070's 81st percentile means it outperforms 81% of all GPUs in the database, while the Arc Pro B70's 50th percentile suggests it sits at the median, though this figure cannot be verified against actual test data. The wins count shows zero for the Intel card and zero for the NVIDIA card in direct head-to-head comparisons, confirming that no side-by-side benchmark results exist in the current records.

Without recorded benchmark data for the Arc Pro B70, a direct performance comparison relies on specification analysis. The RTX 4070's FP32 advantage of 6.21 TFLOPS represents a 27% lead in peak shader throughput, which typically translates to higher frame rates in gaming and most compute tasks. The Arc Pro B70's memory advantages, 32 GB versus 12 GB and 608.0 GB/s versus 504.2 GB/s, suggest it would win in scenarios that exceed the RTX 4070's memory capacity, but the measured data cannot confirm this hypothesis with quantitative results.
