Intel Arc Pro B65 vs NVIDIA RTX 3500 Mobile Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for these two GPUs shows no head-to-head benchmark results available in the database. The benchmark arrays for both the Intel Arc Pro B65 and the NVIDIA RTX 3500 Mobile Ada Generation are empty, and the wins counter for each side sits at zero. Consequently, direct performance comparisons cannot be established from the measurements on file.

What the database does contain are the theoretical compute ceilings for each part, which provide a reference point for raw capability. The Intel Arc Pro B65 delivers 12.29 TFLOPS of FP32 throughput, while the NVIDIA RTX 3500 Mobile Ada Generation reaches 15.82 TFLOPS. That puts the NVIDIA part roughly 28.7% ahead in single-precision floating-point work based on the recorded specifications. In FP16, the Intel GPU more than doubles its FP32 rate to 24.58 TFLOPS with a 2:1 ratio, while the NVIDIA GPU holds a flat 15.82 TFLOPS at a 1:1 ratio. For workloads that leverage FP16 acceleration, the Intel part has a clear theoretical advantage.

Pixel throughput also splits the two. The Intel Arc Pro B65 posts 192.0 GPixel/s, which is 94% higher than the NVIDIA part's 98.88 GPixel/s. This suggests a substantial edge in fill-rate-bound scenes, such as high-resolution rasterization. Texture rate goes the other way: the Intel GPU achieves 384.0 GTexel/s versus 247.2 GTexel/s for the NVIDIA GPU, a 55.3% lead for Intel. Both GPUs share the same TMU count at 160, so the difference stems from clock speeds and architecture efficiency rather than texture unit quantity.

Memory bandwidth is another significant split. The Intel Arc Pro B65 uses a 256-bit bus with 32 GB of GDDR6 at 608.0 GB/s. The NVIDIA RTX 3500 Mobile Ada Generation uses a 192-bit bus with 12 GB of GDDR6 at 432.0 GB/s. Intel's bandwidth advantage of 40.7% directly affects throughput for large datasets and high-resolution textures. The NVIDIA part does counter with a higher shading unit count, 5120 versus 2560, and more RT cores, 40 versus 20, plus 160 tensor cores that the Intel GPU lacks entirely. These architectural differences point to divergent strengths: NVIDIA for ray tracing and tensor-accelerated workloads, Intel for raw rasterization and FP16 compute.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc Pro B65 uses the Xe2-HPG architecture on the BMG-G21 chip, part of the Battlemage (Pro Series) generation. The NVIDIA RTX 3500 Mobile Ada Generation uses Ada Lovelace on the AD104 chip, belonging to the Ada-MW generation. Both are fabricated on a 5 nm process at TSMC, but the transistor counts differ sharply. The NVIDIA chip packs 35,800 million transistors on a 294 mm² die, while the Intel chip contains 19,600 million transistors on a 272 mm² die. That translates to a transistor density of 121.8M per mm² for NVIDIA versus 72.1M per mm² for Intel.

Clock behavior is markedly different. The Intel Arc Pro B65 runs at a fixed 2400 MHz for both base and boost, which is a high sustained clock. The NVIDIA RTX 3500 Mobile Ada Generation runs at a 1110 MHz base and 1545 MHz boost, a much lower clock range. This explains how Intel achieves its high pixel and texture rates despite fewer shading units: raw clock speed compensates for the architectural count. Memory clocks also differ, with Intel at 2375 MHz (19 Gbps effective) and NVIDIA at 2250 MHz (18 Gbps effective).

Memory configuration is a major architectural divider. Intel offers 32 GB of GDDR6 on a 256-bit bus, yielding 608.0 GB/s. NVIDIA offers 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The Intel card has 80 ROPs versus NVIDIA's 64, which aligns with its higher pixel rate. Both have 160 TMUs. Ray tracing hardware differs: Intel includes 20 RT cores, while NVIDIA includes 40 RT cores plus 160 tensor cores. The tensor cores provide dedicated AI acceleration, a feature absent from the Intel part.

Power and physical design also separate the two. The Intel Arc Pro B65 is a dual-slot card with a 200 W TDP and a single 8-pin power connector, requiring a 550 W suggested power supply. It uses a PCIe 5.0 x16 bus interface and outputs 4x DisplayPort 2.1. The NVIDIA RTX 3500 Mobile Ada Generation is an IGP (integrated graphics processor) with a 100 W TDP and no power connectors, using a PCIe 4.0 x16 interface. Its display outputs are listed as portable device dependent. The NVIDIA part is clearly designed for mobile integration, while the Intel part is a standalone add-in board.

API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Release timing differs, with the NVIDIA GPU launching on 2023-03-20 and the Intel GPU on 2026-03-31. The NVIDIA part has a named predecessor, Ampere-MW, and successor, Blackwell-MW, while the Intel part has neither listed.

The Verdict

The database does not include direct benchmark scores for either GPU, so the verdict rests on specification-level analysis. For pure rasterization throughput, the Intel Arc Pro B65 holds clear advantages: 94% higher pixel rate, 55.3% higher texture rate, and 40.7% more memory bandwidth. Its 32 GB frame buffer is more than double the NVIDIA part's 12 GB, which matters for large-scale compute or multi-model datasets. The fixed 2400 MHz clock also suggests consistent sustained performance without boost variability.

For compute workloads that use FP32 or tensor operations, the NVIDIA RTX 3500 Mobile Ada Generation has the edge. Its 15.82 TFLOPS FP32 output is 28.7% higher than Intel's 12.29 TFLOPS. The 160 tensor cores provide dedicated hardware for AI inference and deep learning tasks, which the Intel part lacks. The 40 RT cores, double Intel's count, give NVIDIA a structural advantage in ray-traced rendering. The lower 100 W TDP also makes it suitable for power-constrained mobile platforms, whereas the Intel card's 200 W TDP requires a desktop-style power delivery system.

The choice depends on workload profile. The Intel Arc Pro B65 suits high-resolution rasterization, large memory footprints, and FP16-heavy compute. The NVIDIA RTX 3500 Mobile Ada Generation suits FP32 compute, tensor-accelerated AI, and ray tracing, all within a mobile power envelope. The data does not show which performs better in real-world applications, only that their theoretical strengths diverge along these lines.
