Intel Arc Pro B65 vs Lisuan Tech LX MAX Comparison

# Intel Arc Pro B65 vs Lisuan Tech LX MAX

The Intel Arc Pro B65 and Lisuan Tech LX MAX occupy the same performance percentile (50th) in the database, yet they approach graphics processing from fundamentally different design philosophies. The Arc Pro B65 uses Intel's Xe2-HPG architecture on a 5 nm TSMC process, while the LX MAX deploys Lisuan Tech's TrueGPU architecture on a 6 nm TSMC node. Both cards target the dual-slot, 550 W suggested PSU segment, but their silicon layouts, memory configurations, and API support create distinct usage profiles.

Where Each One Wins

The Intel Arc Pro B65 presents a clear advantage in memory capacity and bandwidth. With 32 GB of GDDR6 on a 256 bit bus, it delivers 608.0 GB/s of bandwidth, compared to the LX MAX's 12 GB on a 192 bit bus at 432.0 GB/s. For workloads that exceed the LX MAX's memory footprint, such as large dataset processing, high-resolution texture streaming, or multi-application workflows, the Arc Pro B65 avoids spillover penalties entirely. The 32 GB allocation also positions it for tasks where the 12 GB ceiling would force frequent data transfers.

The Lisuan Tech LX MAX counters with raw compute throughput. Its FP32 rate of 24.58 TFLOPS doubles the Arc Pro B65's 12.29 TFLOPS, and its FP16 rate of 49.15 TFLOPS (2:1) similarly doubles the Arc Pro B65's 24.58 TFLOPS (2:1). This compute advantage stems from the LX MAX's 6144 shading units, which outnumber the Arc Pro B65's 2560 shading units by a factor of 2.4. Applications that scale with shader count, including certain rendering engines, physics simulations, and compute-heavy filters, will favor the LX MAX.

The texture and pixel throughput metrics show parity. Both cards achieve 384.0 GTexel/s and 192.0 GPixel/s, meaning texture-heavy workloads and fill-rate-bound scenarios perform identically on paper. The LX MAX does have more TMUs (192 vs 160) and ROPs (96 vs 80), but the clock rates and architecture efficiency result in equal output rates in the recorded data.

The Arc Pro B65 wins on interface modernity. It uses PCIe 5.0 x16 and DisplayPort 2.1 outputs, while the LX MAX uses PCIe 4.0 x16 and DisplayPort 1.4a. For systems with PCIe 5.0 support, the Arc Pro B65 benefits from doubled interconnect bandwidth. DisplayPort 2.1 enables higher refresh rates and resolutions over a single cable compared to DisplayPort 1.4a, which matters for multi-monitor or high-bandwidth display configurations.

Architecture Differences

The two GPUs diverge at the silicon level. The Intel Arc Pro B65 is built on the BMG-G21 chip, part of the Battlemage (Pro Series) generation, using Xe2-HPG architecture. It contains 19,600 million transistors on a 272 mm² die, resulting in a transistor density of 72.1M per mm². The Lisuan Tech LX MAX uses the 7G106 chip from the 7G100 generation, with TrueGPU architecture. Its transistor count and die size are recorded as unknown, but the 6 nm process node suggests a different manufacturing trade-off compared to the Arc Pro B65's 5 nm node.

The Arc Pro B65 includes 20 ray tracing cores, while the LX MAX lists no ray tracing cores in the database. This gives Intel's card a dedicated hardware path for ray tracing workloads. The LX MAX compensates with a much higher shader count, which can handle some ray tracing via compute shaders but without dedicated acceleration hardware.

Clock behavior also differs. The Arc Pro B65 runs at a fixed 2400 MHz for both base and boost clocks, with memory at 2375 MHz (19 Gbps effective). The LX MAX has no recorded base or boost clock for the core, only a memory clock of 2250 MHz (18 Gbps effective). This makes direct clock-to-clock comparisons impossible, but the compute throughput figures already capture the performance difference.

API support shows a split on Vulkan versions. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the Arc Pro B65 supports Vulkan 1.4 while the LX MAX supports Vulkan 1.3. Applications requiring Vulkan 1.4 features will run only on the Arc Pro B65.

Physical dimensions are recorded only for the LX MAX: 248 mm length (9.8 inches), 118 mm height (4.6 inches), and 48 mm width (1.9 inches). The Arc Pro B65's dimensions are not listed. Both cards are dual-slot, but the LX MAX uses a 1x 16-pin power connector while the Arc Pro B65 uses a 1x 8-pin connector. The LX MAX has a higher TDP of 225 W, compared to the Arc Pro B65's 200 W.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the Intel Arc Pro B65 and the Lisuan Tech LX MAX. The wins and benchmark arrays are empty, and both cards sit at the 50th percentile among all GPUs with an average benchmark score of zero. This means the comparison must rely on the recorded specification data, which reveals two distinct performance profiles.

The LX MAX's FP32 advantage is the largest single gap in the comparison. At 24.58 TFLOPS, it delivers exactly double the Arc Pro B65's 12.29 TFLOPS. This margin matters for compute-bound workloads where shader throughput dominates execution time. The LX MAX's 6144 shading units provide the hardware basis for this doubling, and its FP16 rate of 49.15 TFLOPS reinforces the pattern. For applications that can use FP16 arithmetic, the LX MAX's throughput advantage remains consistent at 2:1.

The Arc Pro B65's memory advantage is equally decisive in the opposite direction. Its 608.0 GB/s bandwidth is 176 GB/s higher than the LX MAX's 432.0 GB/s, a 40.7% margin. The 32 GB capacity is 20 GB higher than the LX MAX's 12 GB, a 166.7% margin. For workloads where data exceeds 12 GB, the Arc Pro B65 can keep data resident on the GPU, while the LX MAX would need to transfer data across the PCIe bus, incurring latency that the compute throughput cannot hide.

Texture and pixel rates are identical at 384.0 GTexel/s and 192.0 GPixel/s. Despite the LX MAX having more TMUs and ROPs, both cards achieve the same output rates in the recorded data. This parity suggests that fill-rate-bound operations, such as basic rasterization or texture sampling without heavy shading, will perform similarly on both cards.

The ray tracing core difference adds another dimension. The Arc Pro B65's 20 ray tracing cores provide dedicated hardware for ray traversal and intersection tests. The LX MAX has no such cores, so ray tracing work would fall to its shaders, which are plentiful but lack specialized acceleration. In hybrid rendering workloads that mix rasterization with ray-traced effects, the Arc Pro B65 may close the compute gap that the LX MAX enjoys in pure FP32 tasks.

Interface differences favor the Arc Pro B65 for data transfer. PCIe 5.0 x16 offers double the bandwidth of PCIe 4.0 x16, which benefits workloads that stream data from system memory or storage. DisplayPort 2.1 supports higher display bandwidth than DisplayPort 1.4a, enabling higher resolutions or refresh rates across the four outputs.

Power consumption slightly favors the Arc Pro B65, with a 200 W TDP versus the LX MAX's 225 W. Both cards suggest a 550 W PSU, so system power requirements are equivalent. The LX MAX's 16-pin connector provides more electrical capacity than the 8-pin connector on the Arc Pro B65, but the lower TDP of the Intel card means its connector is sufficient.

The release dates sit close together: the LX MAX launched on 2026-03-16, and the Arc Pro B65 followed on 2026-03-31. Both are active products, so the comparison reflects current market positions. The LX MAX's TrueGPU architecture with 6144 shading units delivers compute density that the Arc Pro B65 cannot match, while the Arc Pro B65's 32 GB memory configuration and PCIe 5.0 interface provide a memory-centric feature set that the LX MAX lacks. Neither card holds a universal advantage; the choice depends on whether the workload prioritizes shader throughput or memory capacity and bandwidth.
