Intel Arc Pro B370 vs NVIDIA L20 Comparison

Where Each One Wins

The Intel Arc Pro B370 and NVIDIA L20 occupy entirely different segments of the hardware spectrum, and the benchmark data reflects that separation clearly. The Intel part is an integrated graphics processor (IGP) built for the Panther Lake mobile platform, while the NVIDIA L20 is a dual-slot server accelerator designed for compute-heavy workloads. The recorded data shows no direct head-to-head benchmark comparisons, but the architectural specifications and the L20's available benchmark scores establish a definitive split in use cases.

The NVIDIA L20 wins decisively in every compute-intensive category. It delivers 59.35 TFLOPS of FP32 performance and 59.35 TFLOPS of FP16 performance with a 1:1 ratio, making it suitable for workloads that require raw floating-point throughput. The L20's Geekbench OpenCL score of 274,276 and Vulkan score of 228,018 place it in the 99th percentile of all GPUs in the database, confirming its position as a high-end compute solution. Its nearest rivals include the NVIDIA L40 with an average score of 284,111 (11.6% higher) and the NVIDIA RTX 6000 Ada Generation with 287,237 (12.6% higher), while it sits 11.6% above the NVIDIA PG506-232 (225,124) and 14.2% above the AMD Radeon PRO W7900D (219,827).

The Intel Arc Pro B370, by contrast, has no recorded benchmark scores in the database and sits at the 50th percentile among all GPUs. Its strengths lie in integration and power efficiency, not absolute performance. With a 25 W TDP and no power connectors, it operates within the thermal envelope of a mobile processor package. The 1280 shading units, 40 texture mapping units, and 20 render output units are modest figures, and the 6.144 TFLOPS FP32 throughput is roughly one-tenth of the L20's capability. The Arc Pro B370 wins in the category of deployment simplicity: it requires no additional cooling solution beyond the host system, takes up no expansion slot, and draws power from the system bus rather than a dedicated connector.

For mobile workstations and compact devices where space and power are constrained, the Intel part is the only viable option of the two. For server racks, AI inference, rendering farms, and professional visualization workloads, the NVIDIA L20 is the clear choice. The data shows no overlap in their intended operating environments.

Architecture Differences

The two processors could hardly be more different internally. The Intel Arc Pro B370 uses the Panther Lake chip with the Xe3-LPG architecture, built on Intel's 3 nm process node. It belongs to the Arc Graphics-WM (Panther Lake) generation and succeeds the HD Graphics-WM. The L20 uses the AD102 chip with the Ada Lovelace architecture, manufactured by TSMC on a 5 nm process. The L20's die contains 76,300 million transistors across a 609 mm² area, yielding a transistor density of 125.3M per mm². The Intel part's transistor count and die size are listed as unknown in the database.

The L20's memory subsystem is a dedicated 48 GB pool of GDDR6 on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The Arc Pro B370 uses system shared memory, with its bandwidth described as system dependent. This is a fundamental architectural distinction: the L20 has its own high-speed memory array, while the Intel part borrows from the host system's memory controller.

Compute resource counts differ by an order of magnitude. The L20 has 11,776 shading units, 368 TMUs, 128 ROPs, 92 RT cores, and 368 tensor cores. The Arc Pro B370 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores, with no tensor core count listed. The L20's pixel rate of 322.6 GPixel/s and texture rate of 927.4 GTexel/s dwarf the Intel part's 48.00 GPixel/s and 96.00 GTexel/s.

Clock behavior also diverges. The L20 runs at a 1440 MHz base clock and 2520 MHz boost, with memory at 2250 MHz (18 Gbps effective). The Intel part idles at 300 MHz and boosts to 2400 MHz, but its memory clock is tied to the system. The L20 uses a 1x 16-pin power connector and requires a 600 W suggested PSU, while the Intel part uses none and lists no suggested PSU. The L20 is a dual-slot card measuring 267 mm in length and 111 mm in height, whereas the Intel part is an IGP with no physical dimensions recorded.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The L20 has 4x DisplayPort 1.4a outputs, while the Intel part's display outputs depend on the portable device in which it is integrated.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc Pro B370 and the NVIDIA L20, so the comparison must rely on the L20's recorded scores and the architectural parameters of both parts. The L20's Geekbench OpenCL score of 274,276 places it firmly in the top percentile of the database. Its Vulkan score of 228,018 is lower but still substantial. The average benchmark score across both tests is 251,147.

Relative to its nearest rivals, the L20 sits in a competitive band. It trails the NVIDIA L40 by 11.6% (284,111 vs. 251,147 average) and the NVIDIA RTX 6000 Ada Generation by 12.6% (287,237 vs. 251,147 average). It leads the NVIDIA PG506-232 by 11.6% (225,124 vs. 251,147) and the AMD Radeon PRO W7900D by 14.2% (219,827 vs. 251,147). These deltas show that the L20 is positioned mid-pack among professional GPUs, not at the absolute top, but well above older or lower-tier workstation parts.

For the Intel Arc Pro B370, no benchmark scores exist in the database. Its 50th percentile ranking indicates it falls in the middle of the overall GPU distribution, but that ranking is based on specifications rather than measured performance. The FP32 throughput of 6.144 TFLOPS is 9.66 times lower than the L20's 59.35 TFLOPS. The pixel rate is 6.72 times lower (48.00 vs. 322.6 GPixel/s), and the texture rate is 9.66 times lower (96.00 vs. 927.4 GTexel/s). The ROP count difference (20 vs. 128) and TMU difference (40 vs. 368) further illustrate the gap.

The L20's 48 GB memory capacity and 864.0 GB/s bandwidth are critical for large dataset workloads. The Intel part's system shared memory approach has no fixed capacity or bandwidth in the database, making its performance dependent on the host platform. In any memory-bound scenario, the L20 holds an insurmountable advantage.
