Intel Arc A380E vs NVIDIA L20 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the Intel Arc A380E and the NVIDIA L20. However, the available performance data for the NVIDIA L20 is substantial, while the Intel Arc A380E carries no benchmark scores in the database. The Intel Arc A380E has an average benchmark score of zero and sits at the 50th percentile among all GPUs. The NVIDIA L20, by contrast, has an average benchmark score of 251,147 and occupies the 99th percentile.

The NVIDIA L20 shows its strength in the Geekbench OpenCL test with a score of 274,276. Its Vulkan result is lower but still strong at 228,018. Comparing the L20 to its nearest rivals in the database provides a clearer picture of its standing. The L20 sits 11.6% above the NVIDIA PG506-232, which has an average score of 225,124. It also leads the AMD Radeon PRO W7900D by 14.2%, as that card averages 219,827. The L20 trails two higher-end NVIDIA workstation parts: the NVIDIA L40, which scores 284,111 and sits 11.6% above the L20, and the NVIDIA RTX 6000 Ada Generation, which scores 287,237 and sits 12.6% above the L20.

The absence of a benchmark score for the Intel Arc A380E means the database cannot confirm any win for that card in measured performance. The wins tally shows 0 for the A380E and 0 for the L20 in direct head-to-head tests, because no such tests exist in the record. The L20's percentile placement, 99 versus 50, indicates a vast performance gulf in the database's overall GPU ranking. The L20's compute figures reinforce this gap: it delivers 59.35 TFLOPS of FP32 performance and the same 59.35 TFLOPS for FP16, whereas the A380E manages 4.096 TFLOPS FP32 and 8.192 TFLOPS FP16. The L20's pixel rate of 322.6 GPixel/s and texture rate of 927.4 GTexel/s dwarf the A380E's 64.00 GPixel/s and 128.0 GTexel/s.

Specification Differences

The two cards differ in nearly every measured specification. The Intel Arc A380E uses the DG2-128 chip built on TSMC's 6 nm process, containing 7,200 million transistors on a 157 mm² die with a transistor density of 45.9M per mm². The NVIDIA L20 uses the AD102 chip on TSMC's 5 nm process, with 76,300 million transistors on a 609 mm² die and a transistor density of 125.3M per mm².

Clock behavior differs significantly. The A380E has a base clock of 2000 MHz and a boost clock of 2000 MHz. The L20 has a base clock of 1440 MHz and a boost clock of 2520 MHz. Memory clocks also differ: the A380E runs at 1937 MHz (15.5 Gbps effective), while the L20 runs at 2250 MHz (18 Gbps effective).

Memory capacity and bandwidth show the largest gap. The A380E has 6 GB of GDDR6 on a 96-bit bus, yielding 186.0 GB/s. The L20 has 48 GB of GDDR6 on a 384-bit bus, yielding 864.0 GB/s.

Compute resources differ sharply. The A380E has 1,024 shading units, 64 TMUs, 32 ROPs, and 8 ray tracing cores. The L20 has 11,776 shading units, 368 TMUs, 128 ROPs, 92 ray tracing cores, and 368 tensor cores. The A380E has no tensor core count listed.

Board design differs as well. The A380E has a TDP of 75 W, a single-slot profile, no power connectors, and a suggested PSU of 250 W. The L20 has a TDP of 275 W, a dual-slot profile, one 16-pin power connector, and a suggested PSU of 600 W. The A380E measures 254 mm by 127 mm by 20 mm, while the L20 measures 267 mm by 111 mm with no width listed.

Interface and output differences: the A380E uses PCIe 4.0 x8 and four DisplayPort 2.0 outputs. The L20 uses PCIe 4.0 x16 and four DisplayPort 1.4a outputs.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Architecture Differences

The Intel Arc A380E is built on the Xe-HPG architecture as part of the Alchemist (Arc 3) generation. Its predecessor is listed as Xe Graphics, and its successor is Battlemage. The NVIDIA L20 uses the Ada Lovelace architecture as part of the Server Ada (Lxx) generation, with the predecessor listed as Server Ampere and the successor as Server Hopper.

The manufacturing processes differ by one node step. The A380E uses TSMC's 6 nm process, while the L20 uses TSMC's 5 nm process. Transistor counts reflect the scale difference: the A380E integrates 7,200 million transistors, while the L20 integrates 76,300 million. Die size also differs, at 157 mm² versus 609 mm², and transistor density is 45.9M per mm² for the A380E versus 125.3M per mm² for the L20.

Compute architecture differs in FP16 handling. The A380E delivers FP16 at an 8.192 TFLOPS rate using a 2:1 ratio relative to FP32, meaning it uses a packed path for half-precision. The L20 delivers FP16 at 59.35 TFLOPS with a 1:1 ratio, meaning its FP16 throughput matches its FP32 throughput. The L20 also includes 368 tensor cores, which are absent from the A380E's specification list, indicating a fundamental difference in AI and matrix compute capability.

Ray tracing hardware differs in count: the A380E has 8 ray tracing cores, while the L20 has 92. The L20's shading unit count of 11,776 is more than eleven times the A380E's 1,024. TMU and ROP counts follow the same pattern: 368 versus 64 TMUs, and 128 versus 32 ROPs.

Release timing and production status differ. The A380E was released on 2024-03-31 and is marked end-of-life. The L20 was released on 2023-11-15 and is marked active. The L20's release predates the A380E by roughly four months, and it remains in production while the A380E has been discontinued.

The architectures also differ in their target positioning. The A380E's display output of four DisplayPort 2.0 connections and 75 W power profile point to a client-oriented, low-power design. The L20's 275 W power draw, 16-pin connector, and 48 GB memory capacity point to a server-oriented compute design. The L20's 99th percentile ranking and strong Geekbench scores in the database confirm its high-end placement, while the A380E's 50th percentile ranking and lack of recorded benchmark scores leave it in a mid-range position.
