Intel Arc Pro B65 vs NVIDIA L4 Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc Pro B65 contains no benchmark scores, while the NVIDIA L4 has two recorded Geekbench results. This makes direct numeric comparison impossible for the Arc Pro B65. The NVIDIA L4 achieves a Geekbench OpenCL score of 140,838 and a Geekbench Vulkan score of 121,306. Its average benchmark score of 131,072 places it in the 95th percentile of all GPUs in the database. The L4 sits within a tight competitive cluster: it trails the NVIDIA GeForce RTX 3090 Ti by only 0.7%, the NVIDIA RTX 4000 Ada Generation by 3.1%, the NVIDIA A10M by 3.1%, and the AMD Radeon PRO W6800 by 3.2%. These deltas indicate that the L4 delivers performance essentially on par with that group, with the largest gap being a 3.2% deficit to the Radeon PRO W6800.

Because the Arc Pro B65 has no benchmark entries, the head-to-head comparison relies on architectural and specification data rather than measured performance. The L4's FP32 compute rate of 30.29 TFLOPS is more than double the Arc Pro B65's 12.29 TFLOPS. The NVIDIA card also carries 7,424 shading units versus 2,560 for Intel, and 240 texture mapping units versus 160. The L4's texture rate of 489.6 GTexel/s exceeds the Arc Pro B65's 384.0 GTexel/s. However, the Arc Pro B65 counters in pixel throughput: 192.0 GPixel/s versus 163.2 GPixel/s for the L4. The Intel GPU also provides substantially higher memory bandwidth at 608.0 GB/s compared to 300.1 GB/s for the NVIDIA card.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc Pro B65 uses the Xe2-HPG architecture, specifically the Battlemage Pro Series generation, built on the BMG-G21 chip. The NVIDIA L4 uses the Ada Lovelace architecture from the Server Ada generation, based on the AD104 chip. Both are manufactured by TSMC on a 5 nm process, but the transistor counts diverge sharply. The L4 packs 35,800 million transistors on a 294 mm² die, yielding a density of 121.8 million transistors per square millimeter. The Arc Pro B65 contains 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per square millimeter. The NVIDIA chip is therefore denser and carries nearly twice the transistor budget.

Memory configurations also differ. The Arc Pro B65 offers 32 GB of GDDR6 on a 256-bit bus, achieving 608.0 GB/s bandwidth. The L4 provides 24 GB of GDDR6 on a 192-bit bus, with bandwidth of 300.1 GB/s. Clock behavior is notably different: the Arc Pro B65 runs at a flat 2400 MHz for both base and boost, while the L4 has a 795 MHz base clock that boosts to 2040 MHz. Memory clocks likewise differ, with the Intel part at 2375 MHz (19 Gbps effective) and the NVIDIA part at 1563 MHz (12.5 Gbps effective).

Feature sets reflect their target markets. The L4 includes 240 tensor cores and 60 RT cores, while the Arc Pro B65 lists 20 RT cores and no tensor core count. The L4's FP16 performance is 30.29 TFLOPS at 1:1 ratio, while the Arc Pro B65 reaches 24.58 TFLOPS at 2:1 ratio. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs separate them clearly: the Arc Pro B65 provides 4x DisplayPort 2.1, while the L4 has no display outputs, confirming its server-oriented role.

Power and physical design diverge substantially. The L4 has a 72 W TDP, uses no power connectors, and fits a single-slot form factor with dimensions of 169 mm length and 56 mm height. The Arc Pro B65 draws 200 W, requires a single 8-pin power connector, and occupies a dual-slot width. The suggested PSU rating is 550 W for the Intel card and 250 W for the NVIDIA card. Bus interfaces differ as well: PCIe 5.0 x16 for the Arc Pro B65 versus PCIe 4.0 x16 for the L4.

The Verdict

The data indicates two GPUs with opposing design priorities. The NVIDIA L4 dominates in raw compute throughput, transistor density, and shading resources. Its 30.29 TFLOPS FP32 performance, 7,424 shading units, and 240 tensor cores position it for compute-heavy server workloads. The recorded benchmark scores confirm this: the L4 sits at the 95th percentile with an average score of 131,072, consistently within 3.2% of several high-end workstation GPUs.

The Intel Arc Pro B65 offers advantages in memory capacity, bandwidth, and pixel throughput. Its 32 GB frame buffer and 608.0 GB/s bandwidth exceed the L4's 24 GB and 300.1 GB/s. The 192.0 GPixel/s pixel rate also leads the L4's 163.2 GPixel/s. These traits favor graphics-intensive tasks with large datasets or high-resolution rendering. The Arc Pro B65 also includes display outputs, making it suitable for workstation use where visual output is required, whereas the L4 has none.

The lack of benchmark data for the Arc Pro B65 prevents a definitive performance ranking. The L4's measured results place it among top-tier accelerators, but the Arc Pro B65's architectural strengths in memory and pixel throughput suggest it targets a different workload profile. Users requiring massive memory bandwidth and display connectivity should consider the Intel option. Users needing maximum FP32 compute and tensor acceleration, based on the available measurements, should select the NVIDIA L4.

The 7,424 shading units, 240 texture mapping units, and 240 tensor cores provide substantial parallel processing capacity. The 489.6 GTexel/s texture rate also exceeds the Intel card's 384.0 GTexel/s. The L4's benchmark results confirm its standing: the 95th percentile ranking and an average score of 131,072 show it competing within 3.2% of several established high-end GPUs.

Intel Arc Pro B65 wins in memory and pixel throughput. The 32 GB frame buffer and 608.0 GB/s bandwidth give it a clear advantage for memory-intensive workloads. The 192.0 GPixel/s pixel rate leads the L4's 163.2 GPixel/s, indicating stronger rasterization throughput. The 256-bit memory bus doubles the L4's 192-bit width, and the 2375 MHz memory clock (19 Gbps effective) far exceeds the L4's 1563 MHz (12.5 Gbps effective).

NVIDIA L4 wins in efficiency and form factor. The 72 W TDP versus 200 W for the Intel card represents a significant power advantage. The L4 requires no power connectors and fits a single-slot design at 169 mm length and 56 mm height, while the Intel card needs a dual-slot footprint and a single 8-pin connector. The L4's transistor density of 121.8 million per square millimeter also indicates a more compact, dense design.
