Intel Arc A380M vs Lisuan Tech LX ULTRA Comparison

# The Verdict

The Intel Arc A380M and Lisuan Tech LX ULTRA occupy entirely different segments of the GPU market, and the recorded data makes that split unambiguous. The Arc A380M is a 35 W MXM module built for compact, power-limited portable systems. It uses 1024 shading units, 64 TMUs, and 32 ROPs, with 8 ray tracing cores and 6 GB of GDDR6 on a 96-bit bus. The LX ULTRA is a 225 W dual-slot desktop card with 6144 shading units, 192 TMUs, 96 ROPs, and 24 GB of GDDR6 on a 192-bit bus. The scale difference is roughly 6x in shading units, 3x in TMUs, and 3x in ROPs, and the memory capacity is 4x larger.

The LX ULTRA delivers 24.58 TFLOPS FP32 performance against 4.096 TFLOPS for the Arc A380M, a 6x gap in raw compute. Memory bandwidth favors the LX ULTRA at 432.0 GB/s versus 186.0 GB/s. Pixel throughput is 192.0 GPixel/s versus 64.00 GPixel/s, and texture throughput is 384.0 GTexel/s versus 128.0 GTexel/s. The data shows the LX ULTRA is the choice for any workload that demands high resolution, large textures, or sustained compute. The Arc A380M is the choice for a chassis that cannot physically accommodate a 268 mm dual-slot card or feed a 225 W part.

The LX ULTRA requires a 550 W suggested PSU and a 16-pin connector, while the Arc A380M has no separate power connector listed and draws 35 W. The Arc A380M uses an MXM-A (3.1) bus interface, meaning it is not a drop-in desktop card. The LX ULTRA uses PCIe 4.0 x16 and fits a standard desktop slot. Anyone building a new desktop system with room for a dual-slot card should select the LX ULTRA. Anyone upgrading a portable device with an MXM slot should select the Arc A380M.

# Architecture Differences

The two GPUs share a 6 nm TSMC manufacturing process and both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The similarities end there. The Arc A380M uses Intel's Xe-HPG architecture on the DG2-128 chip, part of the Alchemist generation for Arc 3 Mobile. The LX ULTRA uses the Lisuan Tech TrueGPU architecture on the 7G105 chip, part of the 7G100 generation. The transistor counts and die sizes for the LX ULTRA are not recorded, while the Arc A380M lists 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9M per mm².

The Arc A380M includes 8 dedicated ray tracing cores. The LX ULTRA lists no ray tracing cores in the database. This is a structural difference, not merely a clock difference. The Arc A380M's feature set is oriented toward ray-traced workloads in mobile form factors, while the LX ULTRA's specifications emphasize raw rasterization and FP32 compute.

The Vulkan support differs slightly. The Arc A380M supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. Both support DirectX 12 Ultimate and OpenGL 4.6, so API compatibility is broadly similar for modern titles, but the Arc A380M has a newer Vulkan revision.

Memory architecture differs substantially. The Arc A380M has 6 GB of GDDR6 with a 96-bit bus, while the LX ULTRA has 24 GB of GDDR6 with a 192-bit bus. The LX ULTRA's memory clock is 2250 MHz with 18 Gbps effective, while the Arc A380M's memory clock is 1937 MHz with 15.5 Gbps effective. The LX ULTRA achieves 432.0 GB/s bandwidth, more than double the Arc A380M's 186.0 GB/s.

# Where Each One Wins

The LX ULTRA wins in every recorded performance metric except where the comparison is not applicable. FP32 compute is 24.58 TFLOPS versus 4.096 TFLOPS, a 6x advantage. FP16 compute is 49.15 TFLOPS versus 8.192 TFLOPS, also a 6x advantage. Pixel rate is 192.0 GPixel/s versus 64.00 GPixel/s, a 3x advantage. Texture rate is 384.0 GTexel/s versus 128.0 GTexel/s, a 3x advantage. Memory bandwidth is 432.0 GB/s versus 186.0 GB/s, a 2.32x advantage.

The Arc A380M wins in power efficiency considerations. Its 35 W TDP allows operation in systems where a 225 W card cannot run. The LX ULTRA demands a 550 W suggested PSU and a 16-pin power connector. The Arc A380M lists no power connector, drawing power from the MXM slot itself. The LX ULTRA is 268 mm long, 112 mm tall, and 40 mm wide. The Arc A380M is an MXM Module with no dimensions recorded, but its form factor is designed for portable devices.

The LX ULTRA wins on memory capacity with 24 GB versus 6 GB. This matters for large datasets, high-resolution textures, and workloads that exceed 6 GB. The Arc A380M's 6 GB is sufficient for lighter workloads but will encounter capacity limits in demanding scenarios.

The Arc A380M wins on Vulkan version support, with Vulkan 1.4 versus Vulkan 1.3. This is a minor advantage but a real one for applications that use newer Vulkan extensions.

# Head-to-Head Benchmarks

The database records no direct benchmark scores for either GPU, so the comparison relies on the specification-derived throughput rates. The largest single-metric gap is in FP32 compute. The LX ULTRA delivers 24.58 TFLOPS against 4.096 TFLOPS for the Arc A380M, a 6x advantage. This is the defining difference between the two products. The LX ULTRA is in a different compute class entirely.

FP16 performance follows the same pattern. The LX ULTRA outputs 49.15 TFLOPS, while the Arc A380M outputs 8.192 TFLOPS with a 2:1 ratio. The LX ULTRA also uses a 2:1 ratio for FP16, so the relative gap remains 6x. Applications that rely on FP16 tensor-style math will see the same ordering as FP32 workloads.

Texture throughput favors the LX ULTRA at 384.0 GTexel/s versus 128.0 GTexel/s, a 3x advantage. This is driven by the LX ULTRA having 192 TMUs versus 64 TMUs. Pixel throughput favors the LX ULTRA at 192.0 GPixel/s versus 64.00 GPixel/s, also a 3x advantage, driven by 96 ROPs versus 32 ROPs. Fill-rate-bound workloads such as high-resolution rasterization will show the same 3x ordering across the board.

Memory bandwidth shows the smallest relative gap, at 432.0 GB/s versus 186.0 GB/s, a 2.32x advantage for the LX ULTRA. The Arc A380M uses a 96-bit bus with 15.5 Gbps effective memory speed, while the LX ULTRA uses a 192-bit bus with 18 Gbps effective memory speed. The wider bus and faster memory combine to give the LX ULTRA more than double the bandwidth.

The Arc A380M has no recorded wins in the head-to-head data, and the LX ULTRA also has no recorded wins because no direct benchmarks exist. The specification data, however, shows the LX ULTRA ahead in every measured throughput category. The Arc A380M's only recorded advantages are its lower TDP, its ray tracing cores, its Vulkan 1.4 support, and its compact MXM form factor. None of these appear as benchmark scores, but they are structural advantages for specific use cases.
