Architecture Differences

The Intel Arc B390 and Lisuan Tech LX 7G100 represent fundamentally different GPU architectures. The Arc B390 uses Intel's Xe3-LPG architecture built on the Panther Lake chip, fabricated on a 3 nm process at Intel's own foundry. The LX 7G100 uses Lisuan Tech's TrueGPU architecture with the 7G106 chip, manufactured by TSMC on a 6 nm process. These process differences alone indicate different design priorities: Intel's 3 nm node targets efficiency and integration, while the 6 nm node from TSMC allows for a larger, more power-hungry design.

The Arc B390 is an integrated graphics processor with system-shared memory, meaning it relies on the host system's RAM for both capacity and bandwidth. The LX 7G100 is a discrete dual-slot card with 12 GB of dedicated GDDR6 memory on a 192-bit bus. This is the single most significant architectural divide: the LX 7G100 has its own high-bandwidth memory subsystem, while the Arc B390's memory performance is system-dependent.

Compute resources differ sharply. The LX 7G100 packs 6144 shading units, 192 TMUs, and 96 ROPs, versus 1536 shading units, 48 TMUs, and 24 ROPs on the Arc B390. The LX 7G100 also has 12 ray tracing cores, though the Arc B390's ray tracing implementation is not specified with a core count. The LX 7G100's pixel rate is 192.0 GPixel/s and texture rate is 384.0 GTexel/s, while the Arc B390 delivers 60.00 GPixel/s and 120.0 GTexel/s.

API support is nearly identical on the DirectX front: both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Arc B390 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. The Arc B390's clock behavior differs fundamentally: it has a base clock of 300 MHz and boost clock of 2500 MHz, while the LX 7G100 has no listed base or boost clocks.

The Arc B390 is an IGP with no power connectors and a 80 W TDP, designed for portable devices with display outputs dependent on the host system. The LX 7G100 is a dual-slot card measuring 294 mm by 120 mm by 49 mm, uses a PCIe 4.0 x16 interface, draws 225 W, and outputs to four DisplayPort 1.4a connectors.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel Arc B390 and Lisuan Tech LX 7G100. The only recorded benchmark score belongs to the Arc B390: 1482 points in 3DMark Steel Nomad DX12, placing it in the 9th percentile of all GPUs. The LX 7G100 has no benchmark entries and an average benchmark score of zero, though its 50th percentile ranking suggests it outperforms half of all GPUs.

The Arc B390's score of 1482 puts it in close competition with several low-end NVIDIA parts. It sits 1.3% above the GeForce GT 520MX (1463), 1.5% above the GeForce 800M (1460), 2.5% above the GeForce GT 625 OEM (1446), and 2.7% above the GeForce GT 710 (1443). These margins are narrow, indicating that the Arc B390 performs in the entry-level segment.

The LX 7G100's theoretical specifications point to a much higher performance class. Its FP32 throughput of 24.58 TFLOPS is over three times the Arc B390's 7.680 TFLOPS. The LX 7G100's memory bandwidth of 432.0 GB/s is a discrete, fixed quantity, whereas the Arc B390's bandwidth is system-dependent and cannot be quantified from the database. The LX 7G100's pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s are similarly three times higher than the Arc B390's figures.

The 50th percentile ranking for the LX 7G100 versus the 9th percentile for the Arc B390 indicates a substantial performance gap, though without recorded benchmark scores for the LX 7G100, the exact magnitude cannot be stated. The data confirms that the LX 7G100 is designed for workloads requiring dedicated memory and high compute throughput, while the Arc B390 targets integrated, low-power scenarios.

The Arc B390's FP16 performance of 15.36 TFLOPS (2:1) and the LX 7G100's 49.15 TFLOPS (2:1) show the latter has more than triple the half-precision compute capacity. Ray tracing support exists on both, but the LX 7G100 lists 12 ray tracing cores while the Arc B390's ray tracing configuration is unspecified.

The Verdict

The Intel Arc B390 is an integrated GPU for portable devices. Its 9th percentile ranking, 1482 Steel Nomad score, and proximity to low-end NVIDIA parts like the GT 710 and GT 520MX place it firmly in entry-level performance territory. Its 80 W TDP, lack of power connectors, and system-shared memory indicate a design focused on mobility and power efficiency rather than raw throughput. The 3 nm Intel process and 1536 shading units support this interpretation: modest compute resources on a leading-edge node.

The Lisuan Tech LX 7G100 is a discrete, dual-slot GPU with a 225 W TDP, 12 GB of GDDR6, and a 550 W suggested power supply. Its 6144 shading units, 24.58 TFLOPS FP32, and 432.0 GB/s bandwidth position it in a much higher performance tier. The 50th percentile ranking, while not based on a recorded benchmark score, aligns with its substantial compute and memory resources. The four DisplayPort 1.4a outputs and PCIe 4.0 x16 interface confirm its role as a desktop add-in card.

Users with integrated-graphics laptops or compact portable systems should look to the Arc B390 for basic 3D acceleration. Users building desktop systems with a dedicated power supply and expecting high-resolution or compute-intensive workloads should consider the LX 7G100. The data shows no overlap in performance class: the LX 7G100's theoretical compute and memory capabilities exceed the Arc B390's by factors of three or more, and its percentile ranking is over five times higher. The choice is not between two similar products but between two entirely different GPU categories.
