Intel Arc Pro B70 vs NVIDIA GeForce RTX 4070 GDDR6 Comparison

Intel Arc Pro B70 and NVIDIA GeForce RTX 4070 GDDR6 target different priorities entirely. The Arc Pro B70 is a professional workstation card built around massive memory capacity and compute throughput, while the RTX 4070 GDDR6 is a consumer GPU focused on rasterization and ray tracing efficiency. The benchmark data shows the RTX 4070 GDDR6 delivers a 3DMark Steel Nomad DX12 score of 4334.5, placing it in the 25th percentile of all GPUs, while the Arc Pro B70 has no recorded benchmark scores and sits at the 50th percentile based on its specifications. The recorded data indicates these are not direct competitors, but rather two solutions for different workloads.

Where Each One Wins

The Intel Arc Pro B70 wins decisively in memory capacity and bandwidth. It carries 32 GB of GDDR6 across a 256 bit bus, yielding 608.0 GB/s of bandwidth. The RTX 4070 GDDR6 has 12 GB on a 192 bit bus, producing 480.0 GB/s. That 2.67x memory capacity advantage and 26.7% bandwidth lead makes the Arc Pro B70 the clear choice for large datasets, high resolution textures, or workloads that exceed the 12 GB frame buffer of the NVIDIA card. In professional rendering, simulation, or AI inference with large models, the Arc Pro B70 avoids memory spills that would cripple the RTX 4070 GDDR6.

The Arc Pro B70 also wins on raw compute throughput in certain areas. Its FP32 rate of 22.94 TFLOPS trails the RTX 4070 GDDR6's 29.15 TFLOPS, but its FP16 rate of 45.88 TFLOPS (2:1 ratio) doubles its FP32 output, while the RTX 4070 GDDR6's FP16 is locked at 29.15 TFLOPS (1:1 ratio). For mixed-precision workloads that leverage FP16, the Arc Pro B70 delivers 57.4% more FP16 throughput than the RTX 4070 GDDR6. The Arc Pro B70 also has higher pixel rate (358.4 GPixel/s vs 158.4 GPixel/s) and texture rate (716.8 GTexel/s vs 455.4 GTexel/s), making it faster at fill-rate-bound tasks.

The NVIDIA RTX 4070 GDDR6 wins on raw FP32 compute, with 29.15 TFLOPS versus 22.94 TFLOPS, a 27.1% advantage. It also has more shading units (5888 vs 4096) and more ray tracing cores (46 vs 32). The RTX 4070 GDDR6's tensor cores (184) give it dedicated hardware for AI acceleration, while the Arc Pro B70 has no tensor core specification in the data. In the only recorded benchmark, the RTX 4070 GDDR6 scores 4334.5 in 3DMark Steel Nomad DX12, and its nearest rivals bracket that score: Intel Iris Pro Graphics 5200 at 4360 (0.6% higher), AMD FirePro W2100 at 4295 (0.9% lower), NVIDIA GeForce 930M at 4388 (1.2% higher), and NVIDIA GeForce GTX 460M at 4282 (1.2% lower). That proximity to integrated and older mobile GPUs suggests the 3DMark Steel Nomad score does not reflect the RTX 4070 GDDR6's full capability, or the test is heavily fill-rate or memory-bound in a way that penalizes this configuration.

Architecture Differences

The Intel Arc Pro B70 uses the BMG-G31 chip with Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. It is built on a 5 nm process at TSMC, with a die size of 368 mm². The transistor count is unknown. The NVIDIA RTX 4070 GDDR6 uses the AD104 chip with Ada Lovelace architecture from the GeForce 40 series. It is also on a 5 nm TSMC process, but its die is smaller at 294 mm², packing 35,800 million transistors, giving a transistor density of 121.8M per mm².

The shading unit counts differ significantly: the Arc Pro B70 has 4096 shading units, while the RTX 4070 GDDR6 has 5888. However, the Arc Pro B70 has more texture mapping units (256 vs 184) and more raster operation processors (128 vs 64). The RTX 4070 GDDR6 has more ray tracing cores (46 vs 32) and adds 184 tensor cores, which the Arc Pro B70 lacks entirely. Clock speeds favor Intel: the Arc Pro B70 runs at 2280 MHz base and 2800 MHz boost, compared to 1920 MHz base and 2475 MHz boost for the RTX 4070 GDDR6. The memory clocks are similar, with the Arc Pro B70 at 2375 MHz (19 Gbps effective) and the RTX 4070 GDDR6 at 2500 MHz (20 Gbps effective).

The Arc Pro B70 uses PCIe 5.0 x16, while the RTX 4070 GDDR6 uses PCIe 4.0 x16. Display outputs differ: the Arc Pro B70 has 1x HDMI 2.1a and 3x DisplayPort 2.1, whereas the RTX 4070 GDDR6 has 1x HDMI 2.1 and 3x DisplayPort 1.4a. Power delivery also differs: the Arc Pro B70 needs a single 8-pin connector and has a 230 W TDP, while the RTX 4070 GDDR6 uses a single 16-pin connector with a 200 W TDP. Both recommend a 550 W power supply.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two GPUs. The only recorded benchmark belongs to the NVIDIA RTX 4070 GDDR6, which scores 4334.5 in 3DMark Steel Nomad DX12. That score places it in the 25th percentile of all GPUs, and its nearest rivals are tightly clustered: Intel Iris Pro Graphics 5200 at 4360 (0.6% higher), NVIDIA GeForce 930M at 4388 (1.2% higher), AMD FirePro W2100 at 4295 (0.9% lower), and NVIDIA GeForce GTX 460M at 4282 (1.2% lower). The Arc Pro B70 has no benchmark entries, so its average score is 0 and its percentile is 50, based on specifications rather than measured performance.

The biggest wins for the Intel Arc Pro B70 come from the specification sheet, not benchmarks. Its memory bandwidth of 608.0 GB/s is 26.7% higher than the RTX 4070 GDDR6's 480.0 GB/s. Its pixel rate of 358.4 GPixel/s is 126.3% higher than 158.4 GPixel/s. Its texture rate of 716.8 GTexel/s is 57.4% higher than 455.4 GTexel/s. Its FP16 throughput of 45.88 TFLOPS is 57.4% higher than 29.15 TFLOPS. Its 32 GB memory capacity is 166.7% larger than 12 GB.

The NVIDIA RTX 4070 GDDR6 wins on FP32 compute, with 29.15 TFLOPS beating 22.94 TFLOPS by 27.1%. It has 43.8% more shading units (5888 vs 4096), 43.8% more ray tracing cores (46 vs 32), and 184 tensor cores where the Arc Pro B70 has none. Its boost clock is lower at 2475 MHz vs 2800 MHz, but its memory clock is slightly higher at 2500 MHz vs 2375 MHz. The RTX 4070 GDDR6 also draws less power at 200 W TDP versus 230 W.

The RTX 4070 GDDR6's 3DMark Steel Nomad score of 4334.5, while modest in percentile terms, is the only measured performance data point in the comparison. The Arc Pro B70's absence from benchmarks means its real-world performance cannot be verified against the recorded data. The percentile ranking of 50 for the Arc Pro B70 versus 25 for the RTX 4070 GDDR6 suggests the database weights the Arc Pro B70's specifications favorably, but without benchmark scores, that ranking carries no measured evidence.

The Verdict

The data supports a clear split by workload. For professionals needing large memory capacity, the Intel Arc Pro B70 is the only choice between these two. Its 32 GB frame buffer, 608.0 GB/s bandwidth, and 256 bit bus handle datasets that would exhaust the RTX 4070 GDDR6's 12 GB. Its higher pixel and texture rates, plus doubled FP16 throughput, make it suited for compute-heavy professional tasks that leverage mixed precision. The Arc Pro B70's newer display outputs (DisplayPort 2.1 vs 1.4a) and PCIe 5.0 interface future-proof connectivity.

For gamers and consumers, the NVIDIA RTX 4070 GDDR6 is the better option based on the recorded data. It has higher FP32 compute (29.15 TFLOPS), more shading units, more ray tracing cores, and dedicated tensor cores for AI workloads. Its 3DMark Steel Nomad DX12 score of 4334.5 provides a measurable performance baseline, and its lower TDP of 200 W versus 230 W makes it more power-efficient. The RTX 4070 GDDR6 is also smaller (240 mm vs 267 mm) and has a lower launch MSRP of 599 USD versus 949 USD for the Arc Pro B70.

The production status of the RTX 4070 GDDR6 is end-of-life, with its successor in the GeForce 50 series, while the Arc Pro B70 is newly released in March 2026. The RTX 4070 GDDR6 has a measured benchmark score and concrete nearest rivals, whereas the Arc Pro B70 has no benchmark entries. The choice depends entirely on whether the workload demands memory capacity and fill rate (Arc Pro B70) or raw FP32 compute and AI acceleration (RTX 4070 GDDR6). The data does not support one as universally superior, only as specialized for different use cases.
