This places it in a competitive mid-to-high tier.

The Verdict

From the recorded data, the Intel Arc B770 has no benchmark scores to analyze, while the NVIDIA GeForce RTX 5070 Ti Mobile has a full suite of measurements. The NVIDIA card's 80th percentile ranking and average score of 35435 indicate strong performance among all tracked GPUs. Its nearest rivals cluster tightly around its score, with deltas ranging from 2.4% ahead (NVIDIA T1000) to 2.1% behind (NVIDIA A2), showing that the RTX 5070 Ti Mobile sits in a dense competitive field.

The Intel Arc B770, despite having no benchmark data, presents a compelling specification sheet. Its 19.66 TFLOPS FP32 output exceeds the NVIDIA card's 17.04 TFLOPS, and its 512.0 GB/s memory bandwidth, while lower than the NVIDIA card's 672.0 GB/s, comes with a larger 16 GB frame buffer versus 12 GB. The Intel card also has a much higher pixel rate (307.2 GPixel/s vs 115.8 GPixel/s) and texture rate (614.4 GTexel/s vs 266.2 GTexel/s).

For users who prioritize raw fill rates, pixel throughput, and larger memory capacity, the Intel Arc B770's specifications point in that direction. For users who need proven benchmark results, lower power draw, and the 80th percentile ranking, the NVIDIA GeForce RTX 5070 Ti Mobile is the only option with recorded performance data. The data does not support a definitive winner without Intel measurements, but the specification differences suggest distinct market positions.

Head-to-Head Benchmarks

No head-to-head benchmark data exists between the Intel Arc B770 and the NVIDIA GeForce RTX 5070 Ti Mobile in the database. The wins counters show 0 for both sides, and the headToHeadBenchmarks array is empty. This absence of direct comparison data means the analysis must rely on the NVIDIA card's standalone benchmarks and the Intel card's specifications.

The NVIDIA GeForce RTX 5070 Ti Mobile delivers a Geekbench OpenCL score of 143870 and a Geekbench Vulkan score of 139213. In PassMark tests, it scores 24004 in G3D, 10101 in GPU Compute, 981 in G2D, 259 in DirectX 9, 237 in DirectX 11, 151 in DirectX 10, and 102 in DirectX 12. These results show strong compute performance in Geekbench, while the PassMark DirectX scores are relatively modest, suggesting the card excels in general compute workloads more than in legacy API tests.

Without Intel benchmark scores, the only spec-based comparison available is theoretical. The Intel Arc B770 has a 15.4% higher FP32 throughput (19.66 vs 17.04 TFLOPS) and a 130.8% higher FP16 throughput (39.32 vs 17.04 TFLOPS). The Intel card also has a 165.4% higher pixel rate (307.2 vs 115.8 GPixel/s) and a 130.8% higher texture rate (614.4 vs 266.2 GTexel/s). These differences are substantial on paper, but without measured performance, they remain theoretical advantages.

Specification Differences

The primary specification differences are stark. Memory capacity: the Intel Arc B770 has 16 GB of GDDR6, while the NVIDIA GeForce RTX 5070 Ti Mobile has 12 GB of GDDR7. Memory bandwidth: NVIDIA leads with 672.0 GB/s versus 512.0 GB/s for Intel. Bus width: Intel uses 256 bit, NVIDIA uses 192 bit. Shading units: NVIDIA has 5888, Intel has 4096. TMUs: Intel has 256, NVIDIA has 184. ROPs: Intel has 128, NVIDIA has 80. RT cores: NVIDIA has 46, Intel has 32. Tensor cores: NVIDIA has 184, Intel has none listed.

Power consumption is the most dramatic difference: Intel's TDP is 225 W, NVIDIA's is 60 W. The Intel card requires a dual-slot cooler and external power connectors, while the NVIDIA card is an IGP with no power connectors. The bus interface also differs: Intel uses PCIe 4.0 x16, NVIDIA uses PCIe 5.0 x16. Display outputs: Intel has 1x HDMI 2.1a and 3x DisplayPort 2.1, while NVIDIA's outputs are listed as "Portable Device Dependent" due to its mobile IGP nature.

Clock speeds show Intel at 2100 MHz base and 2400 MHz boost, versus NVIDIA at 847 MHz base and 1447 MHz boost. Die size: Intel's is 368 mm², NVIDIA's is 263 mm². Transistor count: NVIDIA lists 31,100 million transistors with a density of 118.3M per mm², while Intel's transistor count is listed as unknown. The NVIDIA card also has a transistor density figure, which Intel does not provide.

Architecture Differences

The Intel Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, belonging to the Battlemage (Arc 7) generation. It is manufactured on a 5 nm process at TSMC, with a die size of 368 mm². Its predecessor is Alchemist, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The architecture features 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, with no tensor cores listed. FP16 compute is delivered at a 2:1 ratio relative to FP32, indicating dedicated FP16 hardware.

The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on the GB205 chip, part of the GeForce 50 Mobile generation. It is also manufactured on a 5 nm process at TSMC, with a die size of 263 mm² and 31,100 million transistors. Its predecessor is GeForce 40 Mobile, and its production status is active. The architecture includes 5888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. FP16 compute is delivered at a 1:1 ratio with FP32, meaning no dedicated FP16 throughput advantage. Both GPUs support the same API versions: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The key architectural difference is the presence of tensor cores in the NVIDIA card (184 of them) versus their absence in the Intel card. Additionally, NVIDIA's Blackwell architecture uses a 1:1 FP16/FP32 ratio, while Intel's Xe2-HPG uses a 2:1 ratio, doubling FP16 throughput. The NVIDIA card also has more RT cores (46 vs 32) and more shading units (5888 vs 4096), while Intel has more TMUs and ROPs.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti Mobile wins in the only category with measured data: benchmark performance. Its 80th percentile ranking and average score of 35435 put it ahead of most GPUs. In Geekbench OpenCL and Vulkan, it scores 143870 and 139213 respectively, indicating strong compute throughput. Its PassMark G3D score of 24004 and GPU Compute score of 10101 further confirm its capabilities. The NVIDIA card also wins on memory bandwidth (672.0 GB/s vs 512.0 GB/s), shading units (5888 vs 4096), RT cores (46 vs 32), tensor cores (184 vs 0), and power efficiency (60 W TDP vs 225 W TDP). Its mobile IGP nature means it requires no power connectors and fits in portable devices.

The Intel Arc B770 wins on several specification fronts despite lacking benchmark data. It has a larger memory capacity (16 GB vs 12 GB), a wider memory bus (256 bit vs 192 bit), higher clock speeds (2400 MHz boost vs 1447 MHz boost), more TMUs (256 vs 184), more ROPs (128 vs 80), and higher pixel and texture rates (307.2 GPixel/s and 614.4 GTexel/s vs 115.8 GPixel/s and 266.2 GTexel/s). It also delivers higher FP32 throughput (19.66 TFLOPS vs 17.04 TFLOPS) and much higher FP16 throughput (39.32 TFLOPS vs 17.04 TFLOPS). For workloads that depend on fill rates, large frame buffers, or FP16 compute, the Intel card's specifications point to advantages.

The data implies a clear split: the NVIDIA card is proven, power-efficient, and strong in compute benchmarks, while the Intel card offers theoretical advantages in rasterization throughput and memory capacity. Without Intel benchmark scores, the database cannot confirm whether those specification advantages translate to real-world wins. The NVIDIA card's 80th percentile standing and tight rivalry with the Quadro GV100 and T1000 suggest it performs consistently across workloads, whereas the Intel card remains an unverified contender with ambitious specifications.
