Intel Arc Pro B70 vs NVIDIA L4 Comparison

Head-to-Head Benchmarks

The recorded data for the NVIDIA L4 shows a substantial performance profile relative to its nearest competitors. Its average benchmark score of 131,072 places it just 0.7% behind the NVIDIA GeForce RTX 3090 Ti, which holds an average score of 131,938. That is an extremely narrow margin, effectively putting the L4 in the same performance class as one of the previous generation’s flagship desktop cards. Against the NVIDIA RTX 4000 Ada Generation, the L4 trails by 3.1%, with the rival scoring 135,218. A similar 3.1% gap exists versus the NVIDIA A10M, which scores 135,230, and the AMD Radeon PRO W6800, which scores 135,396, also a 3.2% deficit.

In terms of raw compute throughput, the NVIDIA L4 delivers 30.29 TFLOPS of FP32 performance. Its FP16 rate is identical at 30.29 TFLOPS, indicating a 1:1 ratio with no boost for half-precision workloads. The Intel Arc Pro B70, by contrast, produces 22.94 TFLOPS of FP32 and 45.88 TFLOPS of FP16, which is a 2:1 ratio. The Intel card’s FP16 advantage is substantial: it offers 51.5% more half-precision throughput than the L4. However, in standard single-precision math, the L4 leads by 32% over the Arc Pro B70.

The pixel and texture rates tell a similar story of division between the two. The Arc Pro B70 reaches 358.4 GPixel/s, which is more than double the L4’s 163.2 GPixel/s, a 119.6% advantage. In texture fill, the Intel card hits 716.8 GTexel/s versus the L4’s 489.6 GTexel/s, a 46.4% lead for Intel. These figures suggest that the Arc Pro B70 is better suited to rasterization-heavy workloads where fill rates dominate, while the L4’s edge in FP32 points toward general compute and simulation tasks.

Memory bandwidth is another clear split. The Arc Pro B70 uses 32 GB of GDDR6 on a 256-bit bus, producing 608.0 GB/s of bandwidth. The L4 has 24 GB of GDDR6 on a 192-bit bus, yielding 300.1 GB/s. The Intel card thus provides more than double the memory bandwidth, a 102.6% increase, and 8 GB more capacity. For workloads that are bandwidth-bound, such as large dataset processing or certain rendering tasks, the Arc Pro B70 holds a decisive advantage.

Clock speeds differ markedly as well. The Arc Pro B70 runs at a base of 2280 MHz and boosts to 2800 MHz, while the L4 runs at a base of 795 MHz and boosts to 2040 MHz. The Intel card’s boost clock is 37.3% higher. The L4 compensates with a much larger shader count: 7424 shading units versus 4096 for the Arc Pro B70. That is an 81.3% higher count, which explains how the L4 achieves higher FP32 throughput despite lower clocks. The L4 also has 60 RT cores and 240 tensor cores, whereas the Arc Pro B70 has 32 dedicated ray tracing units and no tensor core count listed in the database.

In the Geekbench OpenCL test, the L4 scores 140,838, and in Geekbench Vulkan it scores 121,306. The database does not list corresponding benchmark scores for the Arc Pro B70, so a direct head-to-head comparison in those specific tests is not possible from the recorded data. The L4’s percentile rank among all GPUs is 95, meaning it outperforms 95% of the graphics cards in the database. The Arc Pro B70’s percentile is 50, placing it exactly at the median. The average benchmark score for the L4 is 131,072, while the Arc Pro B70 carries an average benchmark score of zero in the database, indicating no benchmark results have been recorded for it yet.

The Verdict

The data points to two different intended usage profiles. The NVIDIA L4 is a low-power server accelerator with a 72 W TDP, a single-slot design, and no display outputs. It draws no auxiliary power connectors and requires only a 250 W suggested power supply. Its 95th percentile ranking and strong FP32 throughput make it a capable compute card for data center tasks, especially those that benefit from tensor cores and a high shader count. Its nearest rival, the RTX 3090 Ti, is only 0.7% faster on average, which positions the L4 as a remarkably efficient option for that performance tier, consuming far less power than the desktop card.

The Intel Arc Pro B70, by contrast, is a dual-slot workstation card with a 230 W TDP, a single 8-pin power connector, and a 550 W suggested power supply. It offers a large 32 GB memory pool, very high bandwidth, and faster pixel and texture fill rates. Its FP16 performance is significantly higher than the L4’s, and its boost clock is substantially higher. The 50th percentile ranking, however, is based on an average benchmark score of zero, which means no measured data exists to confirm its real-world standing. The reader should treat the Arc Pro B70’s performance claims as provisional until database benchmarks are recorded.

Who should pick which? Strictly from the recorded data, the L4 is the proven performer with a 95th percentile rank and concrete Geekbench scores. It suits environments where power efficiency, compactness, and compute throughput matter more than display output or memory bandwidth. The Arc Pro B70, on paper, suits workloads that need more memory, higher bandwidth, and greater fill rates, particularly FP16-heavy tasks. But without benchmark scores in the database, its actual performance relative to the L4 cannot be verified. The L4 is the safer choice based on evidence; the Arc Pro B70 is a speculative pick for bandwidth-hungry rendering or compute tasks.

Physical dimensions differ as well. The Arc Pro B70 measures 267 mm in length, 110 mm in height, and 39 mm in width. The L4 measures 169 mm in length and 56 mm in height, with no width listed. The bus interfaces differ: PCIe 5.0 x16 for Intel, PCIe 4.0 x16 for NVIDIA. Display outputs are present on the Intel card (one HDMI 2.1a, three DisplayPort 2.1) and absent on the NVIDIA card. The Intel card has a launch MSRP of 949 USD; the L4 has no launch MSRP recorded. The L4’s production status is Active, while the Arc Pro B70 has no production status listed.

Architecture Differences

The Intel Arc Pro B70 is built on the BMG-G31 chip using the Xe2-HPG architecture, belonging to the Battlemage Pro Series generation. It is fabricated on a 5 nm process at TSMC, with a die size of 368 mm². Transistor count is unknown. The NVIDIA L4 uses the AD104 chip with the Ada Lovelace architecture, part of the Server Ada generation. It is also fabricated on a 5 nm process at TSMC, but with a smaller die size of 294 mm². The L4 contains 35,800 million transistors, giving a transistor density of 121.8 million per mm². The Arc Pro B70’s transistor density is not recorded.

The L4’s FP16 and FP32 performance are equal at 30.29 TFLOPS each, reflecting a 1:1 throughput ratio. The Arc Pro B70’s FP16 is double its FP32, at 45.88 TFLOPS versus 22.94 TFLOPS, indicating a 2:1 ratio. This suggests the Intel architecture is designed to accelerate half-precision workloads, while the NVIDIA architecture treats both precisions equally.

The L4 has a significantly higher number of RT cores, 60 versus 32 for the Arc Pro B70, and it includes 240 tensor cores, a feature category not listed for the Intel card. The L4’s predecessor is listed as Server Ampere, and its successor is Server Hopper, placing it in a clear server product lineage. The Arc Pro B70 has no predecessor or successor listed in the database.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature sets are identical. The L4’s release date is March 2023, while the Arc Pro B70’s release date is March 2026. The L4’s memory clock is 1563 MHz with 12.5 Gbps effective speed; the Arc Pro B70’s memory clock is 2375 MHz with 19 Gbps effective speed. The Intel card offers a wider memory bus and more memory chips, while the NVIDIA card uses a narrower bus but compensates with more shading units and tensor cores. The architectural split is clear: Intel’s design emphasizes bandwidth, fill rates, and half-precision throughput, while NVIDIA’s design emphasizes compute density, ray tracing, and tensor acceleration within a very low power envelope.
