Intel Arc Pro B70 vs NVIDIA GeForce RTX 4070 AD103 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark scores for the Intel Arc Pro B70 and the NVIDIA GeForce RTX 4070 AD103. Both entries list empty benchmark arrays, zero average scores, and zero wins for either side. This absence of measured performance data means that any numerical comparison must rely strictly on the architectural and specification differences documented in the database.

The most significant raw compute advantage belongs to the NVIDIA GeForce RTX 4070 AD103. Its FP32 throughput stands at 29.15 TFLOPS, which is 27% higher than the Intel Arc Pro B70's 22.94 TFLOPS. The NVIDIA card also carries more shading units, 5888 versus 4096, and more RT cores, 46 versus 32. These figures indicate that in pure rasterization and ray tracing workloads where the full shader array can be utilized, the RTX 4070 AD103 should deliver measurably higher frame rates.

However, the Intel Arc Pro B70 counters in several specific throughput metrics. Its pixel rate of 358.4 GPixel/s exceeds the RTX 4070 AD103's 158.4 GPixel/s by a factor of 2.26. Likewise, its texture rate of 716.8 GTexel/s is 57% higher than the NVIDIA part's 455.4 GTexel/s. These differences stem from the Intel card's larger ROP count, 128 versus 64, and TMU count, 256 versus 184. For workloads that are fill-rate limited, such as high-resolution shadow mapping or certain post-processing effects, the Arc Pro B70 holds a clear advantage on paper.

Memory bandwidth also favors Intel. The Arc Pro B70 provides 608.0 GB/s of bandwidth, which is 21% higher than the RTX 4070 AD103's 504.2 GB/s. This advantage is supported by a wider 256-bit memory bus versus the NVIDIA card's 192-bit bus. The Intel card also carries 32 GB of GDDR6 memory, which is 20 GB more than the RTX 4070 AD103's 12 GB of GDDR6X. For large datasets, AI inference models, or rendering scenes that exceed the NVIDIA card's memory capacity, the Arc Pro B70 avoids fallback to system memory.

Clock speeds show the Intel card operating at a higher frequency envelope. Its base clock is 2280 MHz and boost clock is 2800 MHz, while the RTX 4070 AD103 runs at 1920 MHz base and 2475 MHz boost. Despite lower clocks, the NVIDIA card achieves higher FP32 output because of its larger shader count. The memory clocks differ similarly: Intel runs at 2375 MHz (19 Gbps effective), while NVIDIA runs at 1313 MHz (21 Gbps effective). The NVIDIA memory operates at a higher data rate per pin, but the Intel card's wider bus produces more total bandwidth.

Where Each One Wins

The Intel Arc Pro B70 wins in memory capacity, memory bandwidth, pixel fill rate, and texture fill rate. These metrics point to workloads that involve massive textures, high-resolution framebuffers, or large in-memory datasets. The 32 GB frame buffer is decisive for GPU compute tasks such as training or inference with models that do not fit in 12 GB. The 2.26x pixel rate advantage and 57% texture rate advantage also make the Arc Pro B70 more capable for 4K and multi-monitor rendering where fill rate becomes the bottleneck.

The NVIDIA GeForce RTX 4070 AD103 wins in raw compute throughput, shader count, RT core count, and tensor core availability. Its 29.15 TFLOPS FP32 output is 27% higher, and it includes 184 tensor cores that the Intel card lacks entirely. These features position the RTX 4070 AD103 for conventional gaming, real-time ray tracing, and DLSS-style AI upscaling workloads. The NVIDIA card also has a lower TDP at 200 W versus 230 W, which suggests lower power draw under sustained load, though the database does not provide measured power consumption figures.

The architectural split is clear: the Arc Pro B70 is oriented toward bandwidth and fill-rate-heavy professional workloads, while the RTX 4070 AD103 is oriented toward shader-heavy and AI-accelerated tasks. The RTX 4070 AD103 also uses GDDR6X memory, which has higher effective data rates per pin, while the Arc Pro B70 uses standard GDDR6.

The transistor count is listed as unknown. The NVIDIA GeForce RTX 4070 AD103 uses the Ada Lovelace architecture on the AD103 chip, belonging to the GeForce 40 generation. It is also fabricated on a 5 nm process at TSMC, with a die size of 379 mm² and a transistor count of 45,900 million, which yields a density of 121.1M transistors per mm².

The Intel card integrates 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. It has no dedicated tensor cores. The NVIDIA card integrates 5888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. This means the NVIDIA chip dedicates more silicon to general-purpose and AI compute, while the Intel chip allocates more resources to texture sampling and pixel output.

Memory architecture differs fundamentally. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus, producing 608.0 GB/s. The RTX 4070 AD103 uses 12 GB of GDDR6X on a 192-bit bus, producing 504.2 GB/s. The Intel card's memory clock is 2375 MHz (19 Gbps effective), while the NVIDIA card runs at 1313 MHz (21 Gbps effective). The higher effective data rate per pin on the NVIDIA card is offset by the wider bus on the Intel card.

The two cards also differ in interface and power delivery. The Arc Pro B70 uses PCIe 5.0 x16, while the RTX 4070 AD103 uses PCIe 4.0 x16. The Intel card draws power from a single 8-pin connector, while the NVIDIA card uses a single 16-pin connector. Both have a suggested PSU rating of 550 W. The Intel card has a TDP of 230 W, which is 30 W higher than the NVIDIA card's 200 W.

Display outputs diverge as well. The Arc Pro B70 provides 1x HDMI 2.1 and 3x DisplayPort 2.1. The RTX 4070 AD103 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a. The Intel card supports the newer DisplayPort standard, which enables higher bandwidth for high-refresh-rate and high-resolution displays.

The Verdict

The data indicates a clear split by workload type. The Intel Arc Pro B70 is the superior choice for tasks that demand large memory capacity, high memory bandwidth, and extreme fill rates. Its 32 GB frame buffer, 608.0 GB/s bandwidth, 2.26x pixel rate advantage, and 57% texture rate advantage make it suited for 4K rendering, large texture sets, and compute workloads that exceed 12 GB. Its FP16 throughput of 45.88 TFLOPS is also 57% higher than the NVIDIA card's 29.15 TFLOPS, which matters for workloads using mixed precision.

The NVIDIA GeForce RTX 4070 AD103 is the better option for shader-bound and AI-accelerated tasks. Its 5888 shading units, 46 RT cores, and 184 tensor cores provide a wider feature set for real-time ray tracing and DLSS-style upscaling. Its FP32 output is 27% higher, and it includes tensor core acceleration that the Intel card completely lacks. The NVIDIA card also runs at a lower TDP of 200 W and has a shorter length of 240 mm versus 267 mm, which may simplify installation in smaller cases.

The release dates differ significantly, with the Intel card launching on 2026-03-25 and the NVIDIA card launching on 2024-02-29. The NVIDIA card is marked as end-of-life, while the Intel card has no production status listed. The launch MSRP for the Intel Arc Pro B70 is 949 USD, while the RTX 4070 AD103 launched at 599 USD.

For users who need maximum memory capacity and fill-rate performance, the Intel Arc Pro B70 is the data-backed selection. For users who need maximum shader throughput and AI acceleration, the NVIDIA GeForce RTX 4070 AD103 is the data-backed selection. The two cards do not compete directly on the same metrics, and the choice should be driven by whether the workload is bandwidth-bound or compute-bound.
