Intel Arc Pro B70 vs NVIDIA GeForce RTX 4070 Ti Comparison

The Verdict

The Intel Arc Pro B70 and NVIDIA GeForce RTX 4070 Ti serve two different buyers with distinct priorities. The RTX 4070 Ti is the established performer, sitting at the 84th percentile among all GPUs in the database, with a recorded average benchmark score of 44795. The Arc Pro B70, by contrast, has no recorded benchmark averages and sits at the 50th percentile, meaning its real-world performance profile is unproven in this database.

The RTX 4070 Ti is the safer pick for anyone needing proven compute performance, especially in rasterization and ray tracing, where its Ada Lovelace architecture and higher FP32 throughput give it a clear head start. The Arc Pro B70 targets a different niche: it offers 32 GB of memory, double the RTX 4070 Ti's 12 GB, and it uses PCIe 5.0, which makes it fit for large dataset workloads, AI inference, or rendering scenes that exceed 12 GB. For a builder who needs to fit massive models or textures into VRAM, the Arc Pro B70 is the only choice between these two. For anyone who wants peak frame rates or reliable compute in existing software, the RTX 4070 Ti is the one to pick.

Architecture Differences

The two cards come from different design philosophies. Intel's Arc Pro B70 uses the Xe2-HPG architecture, built on a 5 nm process at TSMC, with the BMG-G31 chip. It is part of the Battlemage (Pro Series) generation. NVIDIA's RTX 4070 Ti uses Ada Lovelace, also on a 5 nm process at TSMC, with the AD104 chip, and belongs to the GeForce 40-series.

The transistor counts differ substantially. The RTX 4070 Ti packs 35,800 million transistors on a 294 mm² die, giving it a transistor density of 121.8M per mm². The Arc Pro B70 has a larger die at 368 mm², but its transistor count is not recorded in the database, so a direct density comparison is impossible from the data.

The shader and compute configurations favor NVIDIA. The RTX 4070 Ti has 7680 shading units, 240 texture mapping units, 80 raster output units, 60 ray tracing cores, and 240 tensor cores. The Arc Pro B70 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores, with no tensor core count listed. NVIDIA also carries dedicated tensor cores, which Intel does not list for this card.

Clock behavior differs as well. The RTX 4070 Ti has a base clock of 2310 MHz and a boost of 2610 MHz. The Arc Pro B70 has a lower base of 2280 MHz but a higher boost of 2800 MHz. Memory technology splits them: the Arc Pro B70 uses GDDR6 at 2375 MHz (19 Gbps effective), while the RTX 4070 Ti uses GDDR6X at 1313 MHz (21 Gbps effective).

The bus interfaces are different generations. The Arc Pro B70 runs on PCIe 5.0 x16, while the RTX 4070 Ti uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API coverage is identical.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the Arc Pro B70 and the RTX 4070 Ti. The RTX 4070 Ti, however, has a full set of individual benchmark scores that reveal its strengths. In 3DMark Steel Nomad (DX12), it scores 5024. In Geekbench OpenCL, it reaches 176953, and in Geekbench Vulkan, it hits 213808. Passmark results show 31624 in G3D, 18396 in GPU Compute, 1200 in G2D, and lower API-specific scores: 352 in DirectX 9, 288 in DirectX 11, 187 in DirectX 10, and 116 in DirectX 12.

The Arc Pro B70 has no benchmark scores recorded in the database, so no direct numeric comparison can be made. What the data does show is the RTX 4070 Ti's standing against its nearest rivals. It sits 0.8% behind the NVIDIA GeForce RTX 5090 Mobile (score 45152), 1.3% behind the AMD Radeon Pro 5500 XT (score 45384), 1.7% behind the Intel Arc A730M (score 45592), and 1.6% ahead of the NVIDIA RTX A6000 (score 44075). These deltas are tight, all within roughly 2%, which indicates the RTX 4070 Ti is in a very competitive performance band.

The RTX 4070 Ti's FP32 throughput of 40.09 TFLOPS is substantially higher than the Arc Pro B70's 22.94 TFLOPS, a gap of roughly 75%. Its FP16 output is 40.09 TFLOPS (1:1), while the Arc Pro B70 delivers 45.88 TFLOPS (2:1), meaning the Intel card can process half-precision data faster in that ratio format. Pixel and texture rates also favor Intel: the Arc Pro B70 outputs 358.4 GPixel/s and 716.8 GTexel/s, versus 208.8 GPixel/s and 626.4 GTexel/s for the RTX 4070 Ti.

Where Each One Wins

The RTX 4070 Ti wins in raw shader compute and ray tracing. Its 7680 shading units and 60 RT cores outnumber the Arc Pro B70's 4096 shading units and 32 RT cores. Its FP32 output of 40.09 TFLOPS is far ahead, and it has 240 tensor cores for AI-accelerated workloads, which the Intel card does not list. The RTX 4070 Ti also holds a higher base clock (2310 MHz) and a proven benchmark record, including a 3DMark Steel Nomad score of 5024 and a Geekbench Vulkan score of 213808. Its nearest rival deltas are all within 2%, confirming it is in a stable, competitive performance tier.

The Arc Pro B70 wins in memory capacity, memory bandwidth, pixel throughput, and texture throughput. It offers 32 GB versus 12 GB, 608.0 GB/s versus 504.2 GB/s, 358.4 GPixel/s versus 208.8 GPixel/s, and 716.8 GTexel/s versus 626.4 GTexel/s. Its boost clock of 2800 MHz is higher than the RTX 4070 Ti's 2610 MHz, and its FP16 rate of 45.88 TFLOPS exceeds NVIDIA's 40.09 TFLOPS. The Intel card also uses PCIe 5.0 x16, a newer bus than the RTX 4070 Ti's PCIe 4.0 x16, and it outputs through DisplayPort 2.1 instead of DisplayPort 1.4a. Its lower TDP (230 W versus 285 W) and lower suggested PSU (550 W versus 600 W) mean it fits into systems with less power headroom.

For a builder choosing between them: the RTX 4070 Ti is the one for gaming, ray-traced scenes, and general compute where software is already optimized for NVIDIA's architecture. The Arc Pro B70 is the one for workloads that exceed 12 GB of VRAM, such as large-scale rendering, machine learning inference with big batch sizes, or multi-display professional setups that want the newer DisplayPort standard. The data shows a clear split: NVIDIA for compute speed, Intel for memory and bandwidth.
