Analysis: Intel Arc B770 vs NVIDIA RTX 3500 Mobile Ada Generation
The Intel Arc B770 and the NVIDIA RTX 3500 Mobile Ada Generation occupy different segments of the graphics hardware spectrum, yet both target demanding compute and rendering workloads. The recorded data shows two distinct approaches to achieving performance: the Arc B770 is a high-power desktop solution built for raw throughput, while the RTX 3500 Mobile is a low-power mobile part designed for integration into portable workstations. This analysis walks through the benchmark splits, architectural differences, and specification gaps to determine where each unit holds an advantage.
Where Each One Wins
Based on the recorded data, the Intel Arc B770 wins in scenarios that demand raw fill rates and computational throughput. Its pixel rate of 307.2 GPixel/s is significantly higher than the 98.88 GPixel/s of the RTX 3500 Mobile. This indicates a clear advantage in rasterization-heavy tasks such as high-resolution rendering and anti-aliasing operations. The texture rate of 614.4 GTexel/s for the Arc B770 versus 247.2 GTexel/s for the NVIDIA part further reinforces this lead, making the Intel card the stronger choice for texture-intensive workloads like modern game engines and complex scene compositing.
The NVIDIA RTX 3500 Mobile Ada Generation counters in areas tied to architecture-specific features and power efficiency. It delivers 40 RT cores compared to 32 on the Arc B770, giving it a higher count of dedicated ray tracing hardware. The NVIDIA part also carries 160 tensor cores, a feature entirely absent from the Intel specification. This makes the RTX 3500 Mobile the preferred option for AI-accelerated tasks such as deep learning inference, denoising, and any workload that can leverage tensor core acceleration. Its 100 W TDP also positions it as the winner in constrained thermal environments, where the 225 W draw of the Arc B770 would be impractical.
The data shows a split: the Arc B770 leads in traditional graphics throughput metrics, while the RTX 3500 Mobile leads in specialized compute features and power efficiency. For users prioritizing raw pixel and texture throughput, the Intel card wins. For those needing ray tracing hardware density and AI acceleration in a mobile form factor, the NVIDIA part takes the lead.
Architecture Differences
The two GPUs come from different architectural families. The Intel Arc B770 uses the Xe2-HPG architecture, built on the Battlemage (Arc 7) generation, with the BMG-G31 chip. The NVIDIA RTX 3500 Mobile uses Ada Lovelace, based on the AD104 chip, and belongs to the Ada-MW generation. Both are fabricated on a 5 nm process at TSMC, so the node technology is identical. The die sizes differ notably: the Intel chip measures 368 mm², while the NVIDIA chip is 294 mm². Despite the smaller die, the NVIDIA chip integrates 35,800 million transistors, giving it a transistor density of 121.8M per mm². The Intel transistor count is unknown in the database, so a direct density comparison cannot be made.
The core configurations reveal a fundamental design divergence. The Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs. The RTX 3500 Mobile has 5120 shading units, 160 TMUs, and 64 ROPs. This explains the benchmark split: Intel allocates more hardware to texture mapping and raster output, while NVIDIA packs more shading units and relies on its tensor cores and RT cores for specialized work. The Intel card provides 32 RT cores; the NVIDIA card provides 40 RT cores plus 160 tensor cores.
Clocks and compute rates also differ. The Arc B770 runs at a base clock of 2100 MHz and a boost clock of 2400 MHz, with FP32 performance of 19.66 TFLOPS and FP16 of 39.32 TFLOPS at a 2:1 ratio. The RTX 3500 Mobile runs at a base clock of 1110 MHz and a boost of 1545 MHz, delivering 15.82 TFLOPS for both FP32 and FP16 at a 1:1 ratio. The Intel card offers higher raw compute, but the NVIDIA card maintains equal throughput across FP32 and FP16, which can simplify mixed-precision workflows.
Power delivery and physical design show the clearest difference in intent. The Arc B770 has a 225 W TDP, requires a dual-slot cooler, and uses a 1x 6-pin plus 1x 8-pin power connector setup, with a suggested PSU of 550 W. The RTX 3500 Mobile has a 100 W TDP, is an IGP (integrated graphics package) with no power connectors, and its display outputs are portable device dependent. The bus interface is PCIe 4.0 x16 for both, but the Intel card offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs, while the NVIDIA part relies on the host device for display connectivity.
Memory configurations also diverge. The Arc B770 uses 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s of bandwidth. The RTX 3500 Mobile uses 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The Intel card has a larger frame buffer and higher bandwidth, which supports its higher fill rates. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is equivalent.
The Verdict
The data indicates that the Intel Arc B770 is the choice for workloads dominated by rasterization throughput. Its 307.2 GPixel/s pixel rate and 614.4 GTexel/s texture rate are roughly 3.1x and 2.5x the respective rates of the RTX 3500 Mobile. Its 16 GB memory buffer and 512.0 GB/s bandwidth provide ample headroom for large textures and high-resolution frame buffers. The 225 W TDP and dual-slot design reflect a desktop-oriented product that assumes adequate cooling and power delivery.
The NVIDIA RTX 3500 Mobile Ada Generation is the choice for mobile workstations and AI-focused tasks. Its 100 W TDP allows integration into laptops without discrete power connectors. The 40 RT cores and 160 tensor cores provide dedicated hardware that the Arc B770 lacks entirely. While its FP32 throughput of 15.82 TFLOPS is lower than the Intel card's 19.66 TFLOPS, the NVIDIA part matches that throughput for FP16 at a 1:1 ratio, which can be advantageous for certain compute kernels. The 12 GB memory capacity and 432.0 GB/s bandwidth are lower than the Intel specs but remain sufficient for portable rendering and inference workloads.
The recorded data does not favor one as universally superior. The Arc B770 wins on raw graphics metrics, memory capacity, and bandwidth. The RTX 3500 Mobile wins on power efficiency, ray tracing core count, tensor core availability, and mobile compatibility. A desktop user prioritizing resolution and texture detail should select the Intel part. A mobile user prioritizing AI acceleration and ray tracing should select the NVIDIA part.

Head-to-Head Benchmarks
The head-to-head benchmark data is empty, but the recorded specification metrics provide a basis for comparison. The largest win for the Intel Arc B770 is in pixel fill rate. At 307.2 GPixel/s, it is 3.1 times the 98.88 GPixel/s of the RTX 3500 Mobile. This translates to a substantial advantage in scenarios where the rasterizer output unit count matters, such as 4K gaming or high-resolution offscreen rendering. The Intel card has 128 ROPs versus 64 on the NVIDIA part, which directly explains this gap.
The texture rate is another decisive Intel win. The Arc B770 achieves 614.4 GTexel/s, which is 2.5 times the 247.2 GTexel/s of the RTX 3500 Mobile. With 256 TMUs versus 160, the Intel card processes texture lookups at a much higher rate. This benefits workloads that sample multiple textures per fragment, such as physically based rendering materials or terrain tessellation.
The NVIDIA RTX 3500 Mobile wins in shading unit count. It has 5120 shading units versus 4096 on the Intel card, a 20% higher count. However, the lower clock speeds on the NVIDIA part (1110 MHz base, 1545 MHz boost versus 2100 MHz base, 2400 MHz boost) result in lower FP32 throughput. The NVIDIA card's FP16 performance matches its FP32 at 15.82 TFLOPS, whereas the Intel card reaches 39.32 TFLOPS FP16, which is 2.5 times its FP32. For applications that can use packed FP16 math, the Intel card offers significantly higher throughput.
Memory bandwidth favors Intel at 512.0 GB/s versus 432.0 GB/s, a difference of 80 GB/s. The 256-bit bus on the Intel card provides the wider path to memory, while the NVIDIA card's 192-bit bus is narrower. The Intel card also has 4 GB more memory, which can matter for very large datasets or high-resolution texture atlases.
Power efficiency favors NVIDIA. The RTX 3500 Mobile delivers 15.82 TFLOPS at 100 W, while the Arc B770 delivers 19.66 TFLOPS at 225 W. Per watt, the NVIDIA card produces approximately 0.158 TFLOPS/W versus 0.087 TFLOPS/W for the Intel card, roughly 1.8 times the efficiency. This is a critical factor for mobile deployments where thermal limits are strict.
The RT core comparison shows a modest NVIDIA advantage: 40 versus 32. The tensor core comparison is absolute in NVIDIA's favor, as the Intel card has no tensor core equivalent in the recorded data. This gives the RTX 3500 Mobile a unique capability for AI workloads that the Arc B770 cannot match through any recorded specification.
