Intel Arc Pro B370 vs Lisuan Tech LX PRO Comparison

Intel Arc Pro B370 and Lisuan Tech LX PRO occupy opposite ends of the GPU spectrum. The Arc Pro B370 is an integrated graphics processor (IGP) built for efficiency and portability, while the LX PRO is a dual-slot, 225 W discrete card aimed at high-throughput workloads. The database shows no direct benchmark wins for either part, as both have zero recorded wins and zero head-to-head benchmark entries. Their performance profiles must therefore be inferred from their architectural specifications and memory configurations.

Where Each One Wins

The Intel Arc Pro B370 wins in scenarios where power draw and physical footprint are the primary constraints. Its 25 W TDP and IGP slot width mean it requires no power connectors and fits entirely within a portable device's existing thermal and electrical design. This makes it the only viable option for ultra-thin laptops, handhelds, or embedded systems where a discrete card cannot be installed. The Lisuan Tech LX PRO, by contrast, cannot operate in such environments. Its 225 W TDP, dual-slot width, and 1x 16-pin power connector demand a desktop chassis with a compatible power supply, specifically a 550 W suggested PSU.

The LX PRO wins in raw compute and memory bandwidth. Its 24 GB of GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth, while the Arc Pro B370 relies on System Shared memory with System Dependent bandwidth. In any workload that saturates memory, such as large dataset manipulation or high-resolution texture streaming, the LX PRO has a decisive structural advantage. The LX PRO also provides 4x DisplayPort 1.4a outputs, enabling multi-monitor setups, whereas the Arc Pro B370's display outputs are Portable Device Dependent, meaning they vary by the host device.

For floating-point throughput, the LX PRO is the clear winner. Its FP32 performance is 24.58 TFLOPS versus 6.144 TFLOPS for the Arc Pro B370, a 4x difference. The LX PRO also doubles this in FP16 to 49.15 TFLOPS, while the Arc Pro B370 reaches 12.29 TFLOPS with a 2:1 ratio. Applications that leverage FP16 acceleration, common in AI inference and certain rendering pipelines, will see proportionally larger gains on the LX PRO.

Architecture Differences

The two GPUs share several API capabilities. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, meaning they can run the same modern game and graphics workloads at a feature level. They diverge on Vulkan support: the Arc Pro B370 supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. This gives the Intel part a newer Vulkan API version, which can matter for specific driver-level optimizations.

The underlying silicon differs fundamentally. The Arc Pro B370 uses Intel's Xe3-LPG architecture on a 3 nm process, fabricated by Intel, as part of the Panther Lake chip. The LX PRO uses a TrueGPU architecture on a 6 nm process from TSMC, with the chip designation 7G105. The process node difference (3 nm versus 6 nm) suggests the Intel part has a density and power efficiency advantage, though the database does not list transistor counts or die sizes for either.

Compute resource allocation is heavily skewed. The LX PRO has 6144 shading units, 192 texture mapping units (TMUs), and 96 raster operation units (ROPs). The Arc Pro B370 has 1280 shading units, 40 TMUs, and 20 ROPs. This means the LX PRO has roughly 4.8x the shading units, 4.8x the TMUs, and 4.8x the ROPs. The LX PRO also has 192 texture units versus 40, and 96 ROPs versus 20. These ratios align closely with the FP32 performance gap, indicating a consistent scaling of the compute pipeline.

Ray tracing hardware is present only on the Intel part, with 10 RT cores listed. The LX PRO has no RT core count recorded. This does not mean the LX PRO lacks ray tracing support, as it still supports DirectX 12 Ultimate, but the database does not document dedicated RT hardware for it. The Arc Pro B370's 10 RT cores provide a specific hardware path for ray-traced effects, though its overall shader throughput is far lower than the LX PRO's.

Memory architecture is the starkest differentiator. The LX PRO has 24 GB of dedicated GDDR6 memory at 2250 MHz with 18 Gbps effective speed, a 192-bit bus, and 432.0 GB/s bandwidth. The Arc Pro B370 uses System Shared memory with no dedicated VRAM, a system-dependent bus width, and system-dependent bandwidth. This means the Intel part's memory performance is entirely contingent on the host device's RAM and memory controller, whereas the LX PRO has fixed, high-bandwidth local memory.

Clock speeds also differ in availability. The Arc Pro B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The LX PRO has no base or boost clock listed for the core, but its memory clock is specified at 2250 MHz. The Intel part's boost clock of 2400 MHz is high for an IGP, but it operates with far fewer cores.

Head-to-Head Benchmarks

The database contains zero head-to-head benchmark entries for these two GPUs, and neither has any individual benchmark scores. The avgBenchmarkScore for both is 0, and both sit at the 50th percentile versus all GPUs. This means there is no direct measured performance comparison available.

Without recorded benchmarks, the analysis relies on theoretical peak rates. The LX PRO's pixel rate is 192.0 GPixel/s versus 48.00 GPixel/s for the Arc Pro B370, a 4x difference. Its texture rate is 384.0 GTexel/s versus 96.00 GTexel/s, also a 4x difference. These figures are directly derived from the ROP and TMU counts multiplied by clock rates, so they represent the maximum fill-rate capacity of each part.

The FP16 advantage for the LX PRO is notable. At 49.15 TFLOPS, it offers 4x the FP16 throughput of the Arc Pro B370's 12.29 TFLOPS. For FP32, the LX PRO's 24.58 TFLOPS is 4x the Intel part's 6.144 TFLOPS. This consistent 4x multiplier across shader throughput, texture rate, and pixel rate indicates that the LX PRO is not just a larger chip, but a proportionally scaled implementation of a similar compute architecture, despite the different underlying designs.

The memory bandwidth gap is even larger. The LX PRO's 432.0 GB/s is not directly comparable to the Arc Pro B370's System Dependent bandwidth, but in practice, even a fast laptop LPDDR5X configuration would struggle to exceed 100 GB/s. This suggests the LX PRO could have a 4x to 5x advantage in memory-bound scenarios, though the database does not provide exact figures for the Intel part's shared memory performance.

The LX PRO also has a higher TDP ceiling at 225 W versus 25 W, a 9x difference. This power budget allows the LX PRO to sustain higher clocks under load, though the database does not list its core boost clock. The Arc Pro B370's 25 W TDP is typical for an IGP, limiting its sustained performance to what the host device's cooling can manage.

The Verdict

The data indicates that the Lisuan Tech LX PRO is the superior choice for any workload that requires dedicated, high-bandwidth memory and massive parallel compute throughput. Its 24 GB GDDR6, 432.0 GB/s bandwidth, and 24.58 TFLOPS FP32 performance place it in a different performance class entirely. Users who need to render high-resolution scenes, process large datasets, or drive multiple 4K displays should select the LX PRO.

The Intel Arc Pro B370 is the only option for systems where a discrete GPU is physically impossible. Its 25 W TDP, IGP slot width, and lack of power connectors make it suitable for portable devices. It also offers a newer Vulkan version (1.4) and dedicated RT cores, which the LX PRO does not list. For light graphics duties, media playback, or basic 3D acceleration on a laptop, the Arc Pro B370 provides a functional integrated solution.

The 4x performance gap in every measurable compute metric is decisive. There is no scenario in the recorded data where the Arc Pro B370 outperforms the LX PRO in raw throughput. The LX PRO's 192 ROPs versus 20, 192 TMUs versus 40, and 6144 shading units versus 1280 give it a structural advantage that no clock speed or efficiency gain can overcome.

The choice is therefore dictated by form factor and power envelope, not performance. If the system can accommodate a dual-slot, 225 W card with a 16-pin connector and a 550 W PSU, the LX PRO is the only rational pick. If the system is a portable device with no expansion slots, the Arc Pro B370 is the only GPU available.
