NVIDIA RTX A1000 vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The benchmark data for this comparison is heavily one-sided, not because of a narrow margin but because the Lisuan Tech LX ULTRA has no recorded benchmark entries in the database. The NVIDIA RTX A1000 carries an average benchmark score of 34207, placing it in the 79th percentile among all GPUs. The LX ULTRA, by contrast, shows an average benchmark score of 0 and sits at the 50th percentile, meaning it has no verified performance data to compare directly.

The RTX A1000's individual benchmark results provide a concrete baseline. In the 3DMark Steel Nomad DX12 test, it scores 969. In Geekbench OpenCL, it reaches 52078, and in Geekbench Vulkan, it posts 49574. These three results establish that the A1000 is a functioning, measurable product within the workstation segment.

Because the LX ULTRA has no benchmark scores, the head-to-head comparison cannot rely on direct performance deltas. Instead, the nearest rival data for the A1000 shows how it fits into the broader market. The A1000 is effectively tied with the NVIDIA RTX A2000 12 GB, which scores 34154, a delta of 0.2%. It also matches the AMD Radeon RX 560 XT at 34133, another 0.2% delta. The NVIDIA TITAN V scores 34355, putting it 0.4% ahead of the A1000. The AMD Radeon RX 480 trails slightly at 33997, a 0.6% delta behind the A1000. These figures show the A1000 sits in a tight cluster where the surrounding cards differ by less than one percentage point in average score.

The LX ULTRA's absence from the benchmark set means the data cannot substantiate any claims of superiority or inferiority. The recorded dataset only supports the A1000's performance profile. The LX ULTRA's 50th percentile ranking, with no average score, indicates a placeholder status rather than a measured outcome.

Architecture Differences

The two GPUs diverge fundamentally at the architecture level. The NVIDIA RTX A1000 uses the GA107 chip based on the Ampere architecture, produced on an 8 nm process at Samsung. The chip contains 8,700 million transistors on a 200 mm² die, yielding a transistor density of 43.5 million per square millimeter. The LX ULTRA uses the 7G105 chip with the TrueGPU architecture, fabricated on a 6 nm process at TSMC. Its transistor count and die size are listed as unknown, so no density figure exists in the database.

Clock behavior also differs. The A1000 has explicit base and boost clocks: 727 MHz base and 1462 MHz boost. The LX ULTRA has no base or boost clock recorded. Memory clocks, however, are specified for both. The A1000 runs memory at 1500 MHz with 12 Gbps effective data rate. The LX ULTRA runs memory at 2250 MHz with 18 Gbps effective, a substantial increase in memory speed.

The compute resources show a large gap in raw counts. The A1000 has 2304 shading units, 72 texture mapping units, and 32 raster output units. It also includes 18 ray tracing cores and 72 tensor cores. The LX ULTRA has 6144 shading units, 192 TMUs, and 96 ROPs. Its ray tracing core and tensor core counts are not recorded, so no comparison is possible on those fronts.

The LX ULTRA delivers significantly higher theoretical throughput. Its pixel rate is 192.0 GPixel/s versus the A1000's 46.78 GPixel/s. Its texture rate is 384.0 GTexel/s versus 105.3 GTexel/s. Its FP32 performance is 24.58 TFLOPS versus 6.737 TFLOPS. The FP16 figures also differ: the LX ULTRA achieves 49.15 TFLOPS with a 2:1 ratio, while the A1000 reaches 6.737 TFLOPS with a 1:1 ratio.

Process node and foundry differences are notable. The LX ULTRA's 6 nm TSMC process is a newer node than the A1000's 8 nm Samsung process. The LX ULTRA also has a much larger power envelope, rated at 225 W TDP compared to the A1000's 50 W TDP. The LX ULTRA requires a 16-pin power connector and a 550 W suggested PSU, while the A1000 uses no power connectors and suggests a 250 W PSU.

API support is similar but not identical. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The A1000 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3.

Where Each One Wins

Based on the recorded data, the NVIDIA RTX A1000 wins in every category where actual measurements exist. It has verified benchmark scores across three tests, a 79th percentile ranking, and an average benchmark score of 34207. These figures place it in a competitive cluster with the RTX A2000 12 GB, the Radeon RX 560 XT, the TITAN V, and the Radeon RX 480, all within one percentage point of each other. The A1000 also leads in practical workstation attributes: a low 50 W TDP, no external power connector, a single-slot form factor, and a compact 163 mm length. It supports Vulkan 1.4, the newer API version, and has been available since April 2024.

The Lisuan Tech LX ULTRA wins in raw specification counts, but only on paper. Its 6144 shading units, 192 TMUs, 96 ROPs, 24 GB memory, 432.0 GB/s bandwidth, 24.58 TFLOPS FP32, and 49.15 TFLOPS FP16 all exceed the A1000's corresponding figures. Its 6 nm process node is newer than the A1000's 8 nm node. Its PCIe 4.0 x16 interface doubles the lane width of the A1000's x8 connection. These specifications suggest higher theoretical capability, but the absence of any benchmark scores means the database cannot confirm that the LX ULTRA translates those specifications into measured performance.

The A1000's wins are empirical. The LX ULTRA's wins are speculative. That distinction matters for any comparison based on data.

The Verdict

The recorded data supports a clear conclusion: the NVIDIA RTX A1000 is the only one of the two with measurable performance. Its average benchmark score of 34207 and 79th percentile ranking come from real test results. Its nearest rivals, including the RTX A2000 12 GB and the TITAN V, are within a fraction of a percentage point, confirming the A1000 sits in a well-established performance tier. Its low power draw, compact dimensions, and lack of power connectors make it a practical option for space-constrained workstation builds.

The Lisuan Tech LX ULTRA presents an unresolved case. Its specifications are substantially higher across the board, from shading units to memory capacity to FP32 throughput. Its 24 GB memory and 432.0 GB/s bandwidth are more than double the A1000's corresponding figures. Its 225 W TDP and dual-slot design indicate a card built for higher sustained workloads. However, without any benchmark scores, the database cannot verify whether those specifications deliver real-world performance. The 50th percentile ranking and average score of 0 reflect the absence of data, not a measured outcome.

The choice depends on what the data can support. For verified performance, the A1000 is the only option with evidence. For theoretical maximums, the LX ULTRA has the superior specification sheet. The A1000 is the safer selection for anyone relying on measured results. The LX ULTRA is a specification-driven alternative whose actual performance remains unverified in the database.
