Intel Arc Pro B390 vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded data for the Intel Arc Pro B390 and Lisuan Tech LX MAX contains no completed benchmark runs. The head-to-head benchmark array is empty, the average benchmark score for both parts is zero, and neither product has registered win counts in the database. The percentile ranking against all GPUs is identical for both at 50, which indicates that with no measured performance data, both units occupy the same neutral position in the database's distribution.

The absence of measured results means that direct performance comparisons cannot be quantified. There are no frame rate averages, no synthetic test scores, and no compute workload results to contrast. This does not reflect poorly on either component; it simply means the database has not yet received validated benchmark submissions for these specific products. The Arc Pro B390 was released in January 2026 according to the recorded release date, while the LX MAX followed in March 2026, so the newer entry has had less time to accumulate test data.

What the database does show is theoretical throughput based on the specification files. The LX MAX carries a peak FP32 figure of 24.58 TFLOPS, while the Arc Pro B390 registers 7.680 TFLOPS. That translates to the LX MAX having roughly three times the raw single-precision compute ceiling. The gap is similar in FP16: the LX MAX lists 49.15 TFLOPS with a 2:1 ratio, against 15.36 TFLOPS for the Arc Pro B390.

Pixel and texture throughput tell the same story. The LX MAX reaches 192.0 GPixel/s and 384.0 GTexel/s, while the Arc Pro B390 manages 60.00 GPixel/s and 120.0 GTexel/s. These are theoretical limits, not measured outcomes, but they establish the relative compute architecture scale of the two parts.

The Arc Pro B390 does hold one notable advantage in the API column: it supports Vulkan 1.4, whereas the LX MAX lists Vulkan 1.3. Both products support DirectX 12 Ultimate (12_2) and OpenGL 4.6, so the API feature sets are otherwise aligned.

FAQ

Q: Which product has the higher peak FP32 compute throughput?

A: The Lisuan Tech LX MAX lists 24.58 TFLOPS of FP32 performance, which is more than triple the 7.680 TFLOPS recorded for the Intel Arc Pro B390.

Q: Do both GPUs support the same DirectX version?

A: Yes, both the Intel Arc Pro B390 and the Lisuan Tech LX MAX support DirectX 12 Ultimate (12_2) and OpenGL 4.6. They differ in Vulkan support: the Arc Pro B390 supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3.

Architecture Differences

The two products come from fundamentally different design lineages. The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture, built on a 3 nm process at Intel's own foundry. The Lisuan Tech LX MAX uses the 7G106 chip with TrueGPU architecture, fabricated on a 6 nm process at TSMC. These are not iterative rivals; they represent separate architectural philosophies from different manufacturers.

The Arc Pro B390 belongs to the Arc Graphics-WM (Panther Lake) generation and is classified as an integrated graphics processor with an IGP bus interface. The LX MAX is a discrete dual-slot card using PCIe 4.0 x16. This placement difference shapes everything downstream: the Arc Pro B390 shares system memory, while the LX MAX has dedicated GDDR6.

Compute resource allocation diverges sharply. The LX MAX fields 6144 shading units, 192 TMUs, and 96 ROPs. The Arc Pro B390 fields 1536 shading units, 48 TMUs, and 24 ROPs. The LX MAX has exactly four times the shading units, TMUs, and ROPs of the Arc Pro B390. The Arc Pro B390 includes 12 ray tracing cores, while the LX MAX does not report a ray tracing core count, which suggests either a different ray tracing implementation or none at all.

The memory architecture is a core differentiator. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective). The Arc Pro B390 uses system shared memory with a system-dependent bandwidth figure, meaning its memory performance is not a fixed property but varies with the host system's memory configuration.

Clock behavior also differs. The Arc Pro B390 has a base clock of 300 MHz and a boost clock of 2500 MHz. The LX MAX lists no base or boost clock in the database. This is not a gap in the LX MAX's capability, but a gap in the recorded specification data.

The manufacturing process favors the Arc Pro B390 at 3 nm versus 6 nm for the LX MAX, though the LX MAX compensates with a much larger compute footprint. Transistor counts and die sizes are listed as unknown for both parts, so the physical scale of each chip cannot be compared from the recorded data.

Power delivery reflects the form factor split. The Arc Pro B390 consumes 80 W and needs no external power connectors. The LX MAX consumes 225 W and uses a single 16-pin connector. The suggested power supply for the LX MAX is 550 W.

Where Each One Wins

The allocation of wins is straightforward in one sense: the database records zero wins for either product because no head-to-head benchmarks exist. The specification data, however, supports a clear division of strengths.

The Lisuan Tech LX MAX wins on raw compute throughput. Its FP32 figure of 24.58 TFLOPS is over three times the Arc Pro B390's 7.680 TFLOPS. The FP16 advantage is similar at 49.15 TFLOPS versus 15.36 TFLOPS. Pixel rate and texture rate also favor the LX MAX by a factor of roughly three: 192.0 GPixel/s and 384.0 GTexel/s versus 60.00 GPixel/s and 120.0 GTexel/s. For workloads that scale with shading unit count, texture mapping, and rasterization throughput, the LX MAX is the stronger part on paper.

The LX MAX also wins on dedicated memory. The 12 GB GDDR6 pool with 432.0 GB/s of bandwidth gives it a fixed, predictable memory subsystem. The Arc Pro B390 depends on system shared memory, so its bandwidth is whatever the host platform provides. Applications that are memory-bandwidth sensitive, such as high-resolution texture streaming or large compute buffers, will favor the LX MAX's dedicated allocation.

The Intel Arc Pro B390 wins on integration and efficiency. Its 80 W TDP is less than a third of the LX MAX's 225 W. It requires no power connectors and occupies no expansion slot, as it is an IGP. For compact systems, portable devices, or platforms without a discrete graphics slot, the Arc Pro B390 is the only viable option of the two. Its 3 nm process node also indicates a denser manufacturing technology, which typically correlates with better performance per watt, though the database does not include measured efficiency figures.

The Arc Pro B390 also holds the API advantage with Vulkan 1.4 support versus Vulkan 1.3 on the LX MAX. Applications that target the newer Vulkan revision may have access to additional features on the Intel part.

The LX MAX wins on physical configurability. It is a dual-slot card with 4x DisplayPort 1.4a outputs, while the Arc Pro B390's display outputs are listed as dependent on the portable device it is integrated into. A system builder who needs a fixed set of display outputs on a discrete card gets that from the LX MAX.

The Arc Pro B390 has a ray tracing core count of 12, while the LX MAX does not list one. If ray tracing workloads matter, the Intel part has a documented hardware path for them. The LX MAX may still handle ray tracing through its compute units, but the database does not confirm that.

In summary, the LX MAX is the compute and memory heavyweight, suited for workloads that demand throughput and dedicated VRAM. The Arc Pro B390 is the integrated, low-power option with a newer Vulkan version and documented ray tracing hardware. Without measured benchmarks, these are architectural conclusions, not performance verdicts.
