The Verdict

The data separates these two cards by purpose rather than simple performance ranking. The NVIDIA GeForce RTX 4060 records a percentile rank of 61 against all GPUs in the database, with an average benchmark score of 17639. Its nearest rivals include the AMD Radeon HD 7790 (avg score 17666, delta -0.2 percent), AMD Radeon 780M (avg score 17588, delta 0.3 percent), AMD Radeon Pro 560 (avg score 17551, delta 0.5 percent), and AMD Radeon Pro 460 (avg score 17509, delta 0.7 percent). This places the RTX 4060 in a tight cluster where it trades fractions of a percent with older discrete cards and integrated graphics.

The Intel Arc Pro B65 has no recorded benchmark scores and a 50th percentile rank, meaning the database treats it as an unmeasured entity. Its design priorities are clear from specifications: massive memory capacity, wide bus, high bandwidth, and a higher pixel rate. The RTX 4060 counters with higher FP32 throughput, more shading units, more RT cores, and tensor cores. Neither card dominates outright. The RTX 4060 is the measured performer with established results. The Arc Pro B65 is the unproven but specification-heavy workstation option.

For users who need the database’s benchmark results, the RTX 4060 is the only one with data. For users who need memory capacity and bandwidth, the Arc Pro B65 offers four times the memory and more than double the bandwidth. The choice depends entirely on whether the workload favors measured gaming or raw memory throughput.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two cards. The RTX 4060 has ten recorded tests; the Arc Pro B65 has none. Therefore, any comparison must rely on the RTX 4060’s scores and the Arc Pro B65’s specifications.

The RTX 4060’s 3DMark Steel Nomad DX12 score is 2302. Its Geekbench OpenCL score is 95057, and its Vulkan score is 48643. In Passmark tests, the RTX 4060 scores 103 in DirectX 10, 175 in DirectX 11, 76 in DirectX 12, 236 in DirectX 9, 1037 in G2D, 19545 in G3D, and 9213 in GPU compute. These scores establish a baseline for a mainstream GPU.

The nearest rivals show how tight the RTX 4060’s competition is. The AMD Radeon HD 7790 scores 17666, just 0.2 percent above the RTX 4060’s 17639 average. The AMD Radeon 780M scores 17588, 0.3 percent below. The AMD Radeon Pro 560 and Pro 460 sit 0.5 and 0.7 percent lower respectively. This data indicates the RTX 4060 performs statistically identically to those older cards in aggregate, despite being a newer generation with different architecture.

The Arc Pro B65’s lack of benchmark data means no direct win can be claimed. However, its specifications suggest advantages in specific metrics. The 608.0 GB/s bandwidth versus 272.0 GB/s is a 336 GB/s gap, which is more than double. The 192.0 GPixel/s versus 118.1 GPixel/s shows a 73.9 GPixel/s advantage. The texture rate of 384.0 GTexel/s versus 236.2 GTexel/s shows a 147.8 GTexel/s lead. These are not benchmark scores, but they are recorded database specifications that indicate where the Arc Pro B65 would likely excel.

The RTX 4060’s FP32 throughput of 15.11 TFLOPS exceeds the Arc Pro B65’s 12.29 TFLOPS by 2.82 TFLOPS, or roughly 23 percent. The RTX 4060 also has more RT cores (24 versus 20) and more shading units (3072 versus 2560). These differences suggest the RTX 4060 holds the advantage in compute-heavy tasks that scale with shader count.

Specification Differences

Memory is the most dramatic difference. The Arc Pro B65 has 32 GB, the RTX 4060 has 8 GB. The bus width is 256 bit versus 128 bit. Bandwidth is 608.0 GB/s versus 272.0 GB/s. Memory clock differs: the Arc Pro B65 runs at 2375 MHz (19 Gbps effective), while the RTX 4060 runs at 2125 MHz (17 Gbps effective).

Shading units: 2560 on the Arc Pro B65, 3072 on the RTX 4060. TMUs: 160 versus 96. ROPs: 80 versus 48. RT cores: 20 versus 24. Tensor cores: none listed for the Arc Pro B65, 96 for the RTX 4060.

Pixel rate: 192.0 GPixel/s versus 118.1 GPixel/s. Texture rate: 384.0 GTexel/s versus 236.2 GTexel/s. FP32: 12.29 TFLOPS versus 15.11 TFLOPS. FP16: the Arc Pro B65 achieves 24.58 TFLOPS (2:1 ratio), while the RTX 4060 achieves 15.11 TFLOPS (1:1 ratio).

Architecture Differences

The Intel Arc Pro B65 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage Pro Series generation. The NVIDIA GeForce RTX 4060 uses the AD107 chip on the Ada Lovelace architecture, from the GeForce 40-series generation. Both use a 5 nm process at TSMC, but the die sizes differ sharply: the Arc Pro B65 measures 272 mm² with 19,600 million transistors, while the RTX 4060 measures 159 mm² with 18,900 million transistors. The Arc Pro B65 has a transistor density of 72.1 million per square millimeter; the RTX 4060 has 118.9 million per square millimeter.

The Arc Pro B65’s transistor count is only 700 million higher than the RTX 4060, but its die is 113 mm² larger. This indicates the Intel chip uses a less dense layout, likely due to the wider memory bus and larger memory controller. The RTX 4060 packs nearly the same transistor count into a much smaller die, resulting in higher density.

Clock behavior also differs. The Arc Pro B65 has a flat base and boost clock of 2400 MHz. The RTX 4060 has a base clock of 1830 MHz and a boost clock of 2460 MHz. The RTX 4060 boosts 60 MHz higher, but the Arc Pro B65 runs at a constant 2400 MHz without a separate game clock.

FP16 performance reveals architectural priorities. The Arc Pro B65 doubles its FP32 rate to 24.58 TFLOPS in FP16, indicating a 2:1 ratio. The RTX 4060 maintains a 1:1 ratio, producing the same 15.11 TFLOPS in FP16 as FP32. This means the Arc Pro B65 has a significant advantage in FP16 workloads, likely relevant for AI inference or compute tasks that use reduced precision.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. No other API differences are recorded.

Where Each One Wins

The Intel Arc Pro B65 wins on memory capacity, bandwidth, pixel rate, texture rate, and FP16 throughput. Its 32 GB memory capacity dwarfs the RTX 4060’s 8 GB, making it suitable for workloads that require large datasets in VRAM, such as rendering scenes with high-resolution textures or running multiple compute tasks simultaneously. The 608.0 GB/s bandwidth is more than double the RTX 4060’s 272.0 GB/s, which directly benefits memory-intensive operations like ray tracing acceleration structures or large framebuffers.

The Arc Pro B65’s 192.0 GPixel/s fill rate and 384.0 GTexel/s texture rate are substantially higher than the RTX 4060’s 118.1 GPixel/s and 236.2 GTexel/s. These metrics favor rasterization-heavy workloads, particularly at high resolutions where pixel throughput becomes a bottleneck. The FP16 throughput of 24.58 TFLOPS suggests the Arc Pro B65 is better equipped for mixed-precision compute workloads.

The NVIDIA GeForce RTX 4060 wins on raw FP32 compute, shading unit count, RT core count, tensor core availability, and measured benchmark scores. Its 15.11 TFLOPS FP32 is 23 percent higher than the Arc Pro B65’s 12.29 TFLOPS. More shading units (3072 versus 2560) and more RT cores (24 versus 20) give it an edge in shader-bound and ray-tracing workloads. The presence of 96 tensor cores, absent from the Arc Pro B65’s specification list, makes the RTX 4060 the only one with dedicated tensor hardware.

The RTX 4060’s benchmark data confirms its measured performance profile. Its average score of 17639 places it in a narrow band with rivals like the AMD Radeon HD 7790 (17666) and AMD Radeon 780M (17588), all within a percentage point. This indicates the RTX 4060 performs at a stable, well-documented level.

The Arc Pro B65 has no benchmark scores, so its wins are purely specification-based. The production status differs: the Arc Pro B65 is active, while the RTX 4060 is end-of-life. The RTX 4060 has a known predecessor (GeForce 30) and successor (GeForce 50), while the Arc Pro B65 has neither listed.

For power efficiency, the RTX 4060 is clearly superior on paper. It draws 115 W versus 200 W, requires a 300 W PSU versus 550 W, and still delivers higher FP32 throughput. The Arc Pro B65 trades power for memory bandwidth and capacity.

The display output difference matters for multi-monitor setups. The Arc Pro B65’s four DisplayPort 2.1 ports support newer display standards, while the RTX 4060’s single HDMI 2.1 and three DisplayPort 1.4a ports offer a more conventional mix. The RTX 4060’s PCIe 4.0 x8 interface is narrower than the Arc Pro B65’s PCIe 5.0 x16, but for most workloads the bandwidth difference may not dominate.

In summary, the Arc Pro B65 wins where memory capacity and fill rates are the primary constraints. The RTX 4060 wins where compute throughput, ray tracing, and measured benchmark stability are the priorities. The absence of Arc Pro B65 benchmark data leaves its real-world performance unverified, so its advantages remain theoretical until measured.
