Intel Arc B580 vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The data presents an asymmetric comparison. The Intel Arc B580 has a full suite of recorded benchmark results, while the Lisuan Tech LX PRO has no recorded benchmark scores in the database. This means the analysis of relative performance is derived entirely from the Arc B580's measured results and the LX PRO's theoretical specifications.

For the Arc B580, the recorded data shows its strongest showing in Geekbench Vulkan with a score of 109,672, followed by Geekbench OpenCL at 92,821. Its Passmark G3D score of 15,748 places it in a competitive position, and its Passmark GPU Compute score of 7,729 indicates solid general compute performance. The average benchmark score of 23,021 across all recorded tests positions it at the 68th percentile of all GPUs in the database.

The Lisuan Tech LX PRO, by contrast, has no measured results. Its 50th percentile ranking appears to be a placeholder derived from its nominal specifications rather than actual testing. The LX PRO's theoretical FP32 throughput of 24.58 TFLOPS is substantially higher than the Arc B580's 13.67 TFLOPS, suggesting an advantage in raw compute-heavy workloads should its architecture scale as expected. However, without measured data, this remains a projection rather than a confirmed result.

The Arc B580 wins in every category where direct measurements exist. The LX PRO can only claim wins in theoretical specifications: higher FP32 and FP16 throughput, more shading units, more texture mapping units, more render output units, and double the memory capacity.

Architecture Differences

The two cards come from different architectural lineages. The Intel Arc B580 uses the BMG-G21 chip built on the Xe2-HPG architecture, part of the Battlemage generation within the Arc 5 series. It is manufactured on a 5 nm process at TSMC and packs 19,600 million transistors onto a 272 mm² die, yielding a transistor density of 72.1 million transistors per square millimeter. The LX PRO uses the 7G105 chip based on a TrueGPU architecture from the 7G100 generation, fabricated on a slightly larger 6 nm process, also at TSMC. Its transistor count and die size are listed as unknown in the database.

The Arc B580 operates with a base and boost clock of 2670 MHz, while the LX PRO's core clocks are not recorded. Memory clocks differ slightly: the Arc B580 runs its GDDR6 at 2375 MHz (19 Gbps effective), while the LX PRO's GDDR6 runs at 2250 MHz (18 Gbps effective). The Arc B580 has a 192-bit memory bus delivering 456.0 GB/s of bandwidth, whereas the LX PRO also uses a 192-bit bus but achieves 432.0 GB/s due to its lower memory clock.

The shading unit counts differ dramatically. The LX PRO carries 6,144 shading units, 192 texture mapping units, and 96 render output units. The Arc B580 has 2,560 shading units, 160 TMUs, and 80 ROPs. The LX PRO's theoretical pixel rate is 192.0 GPixel/s compared to the Arc B580's 213.6 GPixel/s, and its texture rate is 384.0 GTexel/s versus 427.2 GTexel/s. Interestingly, despite having fewer units, the Arc B580's higher core clock gives it the edge in both pixel and texture throughput rates.

Ray tracing support differs as well. The Arc B580 includes 20 dedicated ray tracing cores; the LX PRO lists no ray tracing cores in the database. The Arc B580 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX PRO matches DirectX 12 Ultimate (12_2) and OpenGL 4.6 but only reaches Vulkan 1.3.

The power delivery configurations also differ. The Arc B580 has a 190 W TDP and uses a single 8-pin power connector with a suggested 450 W power supply. The LX PRO draws more power at 225 W TDP, uses a 16-pin connector, and recommends a 550 W power supply. The Arc B580 connects via PCIe 4.0 x8, while the LX PRO uses PCIe 4.0 x16.

Display outputs show a clear divergence. The Arc B580 provides one HDMI 2.1a port and three DisplayPort 2.1 outputs. The LX PRO offers four DisplayPort 1.4a outputs and no HDMI port.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two products. The winsA and winsB counters both stand at zero, and the headToHeadBenchmarks array is empty. This absence of direct comparative measurements means that any performance assessment must be inferred from the Arc B580's standalone results and the LX PRO's theoretical specifications.

The Arc B580's recorded scores establish a baseline. Its 3DMark Steel Nomad DX12 score of 3,068 shows its DirectX 12 capability. The Geekbench OpenCL score of 92,821 and Vulkan score of 109,672 indicate strong cross-API performance. Passmark results show 15,748 in G3D, 7,729 in GPU Compute, 709 in G2D, and API-specific scores of 183 for DirectX 9, 128 for DirectX 11, and 76 for both DirectX 10 and DirectX 12.

Against its nearest rivals in the database, the Arc B580's average benchmark score of 23,021 places it nearly level with the AMD Radeon RX 580 2048SP at 23,061, a difference of just 0.2% in favor of the AMD card. It sits 0.6% ahead of the NVIDIA GeForce RTX 2080 at 22,895, 0.7% behind the NVIDIA GeForce RTX 3080 at 23,172, and 1% behind the NVIDIA P106-100 at 23,249. These narrow margins indicate that the Arc B580 performs within a tight band around these established products.

The LX PRO's theoretical FP32 figure of 24.58 TFLOPS suggests it could outperform the Arc B580 in raw compute scenarios, but the absence of measured results prevents confirmation. The Arc B580's higher pixel rate of 213.6 GPixel/s compared to the LX PRO's 192.0 GPixel/s, and its higher texture rate of 427.2 GTexel/s versus 384.0 GTexel/s, indicate that the Intel card may retain an advantage in fill-rate-bound workloads despite the LX PRO's higher unit counts.

The Verdict

The data supports a clear but conditional conclusion. The Intel Arc B580 is a fully measured product with verified performance across multiple benchmark suites. Its average score of 23,021 places it in the 68th percentile of all GPUs, and its closest rivals, all within 1% of its average score, include the AMD Radeon RX 580 2048SP, NVIDIA GeForce RTX 2080, NVIDIA GeForce RTX 3080, and NVIDIA P106-100. These margins, ranging from 1% behind to 0.6% ahead, show that the Arc B580 delivers performance consistent with that established group.

The Lisuan Tech LX PRO presents a specification sheet with significant theoretical advantages: 24 GB of memory versus 12 GB, 6,144 shading units versus 2,560, and 24.58 TFLOPS FP32 versus 13.67 TFLOPS. The LX PRO also consumes more power at 225 W TDP versus 190 W and uses a 16-pin connector with a 550 W suggested power supply. Its 6 nm process node is larger than the Arc B580's 5 nm node, and its transistor count and die size remain unknown.

The Arc B580 wins on measured evidence. The LX PRO wins on paper specifications. The Arc B580 offers verified performance with modern display outputs including HDMI 2.1a and DisplayPort 2.1, plus ray tracing hardware. The LX PRO offers double the memory and higher theoretical compute, but no ray tracing cores, older DisplayPort 1.4a outputs, no HDMI, and no benchmark data to validate its claims.

For users who prioritize confirmed, tested performance, the Intel Arc B580 is the only option with supporting data. For users who require large memory capacity for specific workloads and are willing to accept unverified specifications, the LX PRO presents a theoretical alternative. The database cannot confirm the LX PRO's real-world behavior, so its selection carries uncertainty that the Arc B580 does not.
