Intel Arc B390 vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The benchmark database contains a single recorded measurement for the Intel Arc B390. It scores 1482 points in 3DMark Steel Nomad DX12. This places the part at the 9th percentile among all GPUs in the database. The Lisuan Tech LX MAX has no recorded benchmark scores at this time. Its average benchmark score is zero, and the database lists no nearest rivals for it. Consequently, a direct head-to-head numerical comparison cannot be constructed from the recorded data.

The Intel Arc B390 sits within a narrow band of comparable results. Its closest rival is the NVIDIA GeForce GT 520MX, which averages 1463 points. The B390 leads that card by 1.3 percent. The NVIDIA GeForce 800M follows at 1460 points, with the B390 ahead by 1.5 percent. The NVIDIA GeForce GT 625 OEM averages 1446 points, a 2.5 percent gap in favor of the B390. The NVIDIA GeForce GT 710 averages 1443 points, placing it 2.7 percent behind the B390. These deltas are modest. The data indicates the B390 occupies a low-end performance tier, clustering within a few percentage points of several older NVIDIA parts.

The Lisuan Tech LX MAX cannot be positioned along the same scale. No benchmark scores exist for it, so no percentile ranking or rival comparisons are available. The recorded data shows winsA at zero and winsB at zero, reflecting the absence of any head-to-head benchmark entries. The LX MAX's performance profile must be inferred from its architectural specifications rather than measured results.

Architecture Differences

The Intel Arc B390 uses the Panther Lake chip and the Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation. The chip is fabricated on a 3 nm process at Intel's own foundry. The Lisuan Tech LX MAX uses the 7G106 chip and the TrueGPU architecture, belonging to the 7G100 generation. It is built on a 6 nm process at TSMC. The process node gap is significant, with the B390 using the smaller fabrication technology.

The B390 is an integrated graphics processor. It uses system shared memory for both capacity and bandwidth, and its memory clock is listed as system shared. The bus interface is IGP, and the slot width is IGP. The LX MAX is a discrete add-in board. It carries 12 GB of GDDR6 memory on a 192 bit bus, with memory clocked at 2250 MHz or 18 Gbps effective. Memory bandwidth reaches 432.0 GB/s. The LX MAX uses a PCIe 4.0 x16 interface and occupies a dual-slot form factor.

The compute resources differ substantially. The B390 features 1536 shading units, 48 texture mapping units, and 24 raster operation units. It includes 12 ray tracing cores. The LX MAX fields 6144 shading units, 192 TMUs, and 96 ROPs. The LX MAX does not list ray tracing cores in the database. This gives the LX MAX four times the shading units, four times the TMUs, and four times the ROPs compared to the B390.

Clock behavior differs as well. The B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The LX MAX has no recorded base or boost clock values. The B390's pixel rate is 60.00 GPixel/s and its texture rate is 120.0 GTexel/s. The LX MAX reaches 192.0 GPixel/s and 384.0 GTexel/s. FP32 throughput for the B390 is 7.680 TFLOPS, while the LX MAX reaches 24.58 TFLOPS. FP16 performance is 15.36 TFLOPS (2:1) for the B390 and 49.15 TFLOPS (2:1) for the LX MAX.

API support is close but not identical. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The B390 supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. The B390's display outputs are portable device dependent, meaning they vary by the host system. The LX MAX provides four DisplayPort 1.4a outputs.

Power characteristics separate the two clearly. The B390 has a TDP of 80 W and no power connectors. The LX MAX has a TDP of 225 W and uses a single 16-pin power connector. The database suggests a 550 W power supply for the LX MAX. The B390 is an IGP, so its power draw is part of the host platform.

Physical dimensions are only recorded for the LX MAX. It measures 248 mm in length, 118 mm in height, and 48 mm in width. The B390 has no listed dimensions because it is an integrated part.

Where Each One Wins

The Intel Arc B390 wins in integration and efficiency. It is an IGP with an 80 W TDP and no external power connectors. Its 3 nm process node is smaller than the LX MAX's 6 nm node. The B390 also holds the only recorded benchmark score in this comparison, 1482 in 3DMark Steel Nomad DX12, which places it ahead of its nearest recorded rivals by 1.3 to 2.7 percent. For systems where the GPU must be part of the processor package, the B390 is the only viable choice between the two. It also supports Vulkan 1.4, a newer version than the LX MAX's 1.3.

The Lisuan Tech LX MAX wins on raw compute resources. It has 6144 shading units versus 1536, 192 TMUs versus 48, and 96 ROPs versus 24. Its FP32 throughput of 24.58 TFLOPS is more than three times the B390's 7.680 TFLOPS. FP16 output of 49.15 TFLOPS (2:1) likewise dwarfs the B390's 15.36 TFLOPS (2:1). The LX MAX provides dedicated 12 GB GDDR6 memory with 432.0 GB/s bandwidth, while the B390 depends on system shared memory. The LX MAX's pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s are each three times the B390's figures. The LX MAX also offers four DisplayPort 1.4a outputs, a discrete PCIe 4.0 x16 connection, and a 225 W TDP suited to a dedicated card.

The use case split follows the data. The B390 suits compact, integrated platforms where power draw and space are constrained. The LX MAX suits workloads that demand high shader throughput, dedicated memory bandwidth, and multiple display outputs. Benchmark validation exists only for the B390, so the LX MAX's real-world standing cannot be confirmed from the database.

The Verdict

The recorded data does not permit a direct performance verdict. The Intel Arc B390 has a measured 3DMark Steel Nomad DX12 score of 1482, placing it at the 9th percentile among all GPUs and within 1.3 to 2.7 percent of several NVIDIA parts in the GT 7xx and 8xx range. The Lisuan Tech LX MAX has no benchmark entries, no average score, and no rival list. Its percentile is listed at 50, but that figure is not supported by any measured result in the database.

On specifications alone, the Lisuan Tech LX MAX holds a commanding lead in shader count, texture units, ROPs, memory capacity, memory bandwidth, and FP32/FP16 throughput. It is a discrete, dual-slot card with a 225 W TDP and a 16-pin power connector. The Intel Arc B390 counters with a smaller 3 nm process, an 80 W TDP, integrated form factor, and a newer Vulkan revision. It also has 12 ray tracing cores, which the LX MAX does not list. The B390's only benchmark result shows it competing with low-end discrete GPUs from several generations ago.

The database supports a clear choice for users who need a dedicated GPU with high compute throughput: the Lisuan Tech LX MAX, based on its specification sheet. The database supports a clear choice for users who need an integrated, low-power part with ray tracing support and a validated benchmark entry: the Intel Arc B390. Any claim about the LX MAX's actual performance relative to the B390 would require recorded measurements that do not currently exist in the database.
