Intel Arc Pro B65 vs NVIDIA RTX 4000 SFF Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data for these two workstation cards is asymmetrical. The Intel Arc Pro B65 has no benchmark scores listed in the database, while the NVIDIA RTX 4000 SFF Ada Generation has two: a Geekbench OpenCL score of 124,812 and a Geekbench Vulkan score of 109,364. This absence of comparable data for the Intel card means a direct numerical head-to-head comparison cannot be constructed from the database. The analysis must therefore rely on the architectural specifications and the relative standing of the NVIDIA card within the wider benchmark database.

The NVIDIA RTX 4000 SFF Ada Generation's average benchmark score is 117,088 across its two recorded tests. The database places this card in the 95th percentile of all GPUs, which indicates it outperforms the vast majority of recorded hardware. Its nearest rivals in the database provide useful context for this score. The NVIDIA GB10 sits 0.3% below with an average score of 117,393, effectively a statistical tie. The AMD Radeon PRO W7700 is 1.6% lower, scoring 118,976, which shows the RTX 4000 SFF Ada is competitive with a high-end workstation alternative. Conversely, the NVIDIA Tesla V100 SXM2 16 GB trails by 2.4% with a score of 114,395, and the NVIDIA RTX A5500 Mobile trails by 2.8% with 113,944. These deltas show that the RTX 4000 SFF Ada Generation sits in a tight performance cluster, with only a few percentage points separating it from several capable rivals.

The Intel Arc Pro B65, by contrast, has an average benchmark score of zero and holds the 50th percentile rank. The database shows no recorded workload results for this card. This does not imply the hardware is incapable, but it does mean the database cannot substantiate any performance claims for it. The GPU's theoretical specifications, such as 12.29 TFLOPS FP32 performance, provide a baseline for what the silicon might deliver, but without recorded scores, any comparison to the NVIDIA card's 19.17 TFLOPS FP32 remains an inference from paper specifications rather than a measured outcome.

Given the absence of benchmark data for the Intel card, the head-to-head section must rely on the only measurable data available: the NVIDIA card's recorded scores and its position relative to other GPUs in the database. The Geekbench OpenCL score of 124,812 is notably higher than its Vulkan score of 109,364, a 14.1% gap that suggests the card performs differently depending on the API workload. This variance is a point of interest for application developers, as it implies the card's compute capabilities are not uniform across all rendering or compute paths.

The Verdict

From the database's perspective, the choice between these two cards is straightforward but unsatisfying. The NVIDIA RTX 4000 SFF Ada Generation has recorded benchmark results that place it in the 95th percentile, with an average score of 117,088. Its nearest rivals are all within a few percentage points, confirming it is a top-tier performer in the database's recorded results. The Intel Arc Pro B65 has no recorded benchmarks, placing it in the 50th percentile by default, which is the median position rather than a reflection of measured performance.

For users who rely on database-verified performance, the NVIDIA card is the only one with substantiated results. The data shows it delivers 19.17 TFLOPS FP32, has 48 RT cores, and includes 192 tensor cores, all of which are recorded specifications. The Intel card offers 12.29 TFLOPS FP32, 20 RT cores, and no tensor core count listed. The NVIDIA card's architectural feature set is more comprehensively documented, which aids in making a data-driven decision.

The Intel Arc Pro B65 does hold advantages in memory capacity and bandwidth on paper: 32 GB of GDDR6 with 608.0 GB/s bandwidth versus the NVIDIA card's 20 GB with 280.0 GB/s. However, the database provides no evidence that these specifications translate into faster or more reliable performance. The NVIDIA card's 95th percentile rank and its proximity to rivals like the AMD Radeon PRO W7700, which is only 1.6% behind, suggest it is a known quantity in terms of expected performance. The Intel card, while architecturally interesting with its Xe2-HPG design, remains unproven in the database's measurements.

The NVIDIA card requires no external power connectors, while the Intel card needs a 1x 8-pin connector. The suggested PSU ratings reflect this gap: 250 W for NVIDIA versus 550 W for Intel. The NVIDIA card also uses PCIe 4.0 x16, while the Intel card uses the newer PCIe 5.0 x16 interface.

Where Each One Wins

Based strictly on the recorded data, the NVIDIA RTX 4000 SFF Ada Generation wins in every measurable category. It has benchmark scores that place it in the 95th percentile, with an average score of 117,088. It delivers 19.17 TFLOPS FP32, has 48 RT cores, and includes 192 tensor cores. Its nearest rivals are all within 2.8% of its average score, confirming it sits at the top of a tight competitive cluster. Its 70 W TDP and lack of power connectors make it a low-power option that requires only a 250 W PSU. The card's recorded dimensions of 168 mm by 69 mm fit a compact SFF form factor.

The Intel Arc Pro B65 wins on paper in memory-related specifications. Its 32 GB of GDDR6 is 60% larger than the NVIDIA card's 20 GB. Its 608.0 GB/s bandwidth is more than double the NVIDIA card's 280.0 GB/s.
