NVIDIA RTX 4000 SFF Ada Generation vs Lisuan Tech LX 7G100 Comparison

The Verdict

The recorded data presents an unusual comparison. The NVIDIA RTX 4000 SFF Ada Generation is a fully characterized, actively benchmarked workstation card with an average benchmark score of 117088 and a percentile ranking of 95 among all GPUs. The Lisuan Tech LX 7G100, by contrast, has no recorded benchmark scores, an average benchmark score of 0, and sits at the 50th percentile. This means the LX 7G100 cannot be positioned as a proven performer; its specifications are present, but its measured behavior is absent.

For users prioritizing verified performance, the RTX 4000 SFF Ada Generation is the only choice supported by data. Its nearest rivals include the NVIDIA GB10 with an average score of 117393 and a delta of -0.3%, the AMD Radeon PRO W7700 at 118976 with a delta of -1.6%, the NVIDIA Tesla V100 SXM2 16 GB at 114395 with a delta of 2.4%, and the NVIDIA RTX A5500 Mobile at 113944 with a delta of 2.8%. These deltas show the RTX 4000 SFF sits within a tight competitive band, slightly behind the GB10 and W7700 but ahead of the Tesla V100 and A5500 Mobile by roughly two to three percent.

The LX 7G100, however, offers raw specification advantages that may appeal to users who prioritize theoretical throughput over measured results. Its FP32 rating of 24.58 TFLOPS exceeds the RTX 4000 SFF's 19.17 TFLOPS, and its FP16 rating of 49.15 TFLOPS (2:1) more than doubles the RTX 4000 SFF's 19.17 TFLOPS (1:1). Its memory bandwidth of 432.0 GB/s also surpasses the 280.0 GB/s of the RTX 4000 SFF. The LX 7G100 also supports a larger 192-bit memory bus versus 160-bit, and more ROPs at 96 versus 64.

The decision hinges on what the data can prove. The RTX 4000 SFF Ada Generation has real benchmark results and a high percentile ranking. The LX 7G100 has no benchmarks, no nearest rivals, and no measured average score. Its specifications promise more compute and memory throughput, but the database contains no evidence of that promise being realized. For mission-critical workloads where verified performance matters, the RTX 4000 SFF is the defensible pick. For experimental use cases where raw specification headroom is the only criterion, the LX 7G100 presents a theoretical argument, but it remains unproven.

Architecture Differences

The two cards diverge fundamentally at the architectural level. The NVIDIA RTX 4000 SFF Ada Generation uses the AD104 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8 million per square millimeter. The Lisuan Tech LX 7G100 uses the 7G106 chip built on an architecture labeled TrueGPU, also fabricated by TSMC but on a 6 nm process. Its transistor count and die size are recorded as unknown, so no density comparison is possible.

The RTX 4000 SFF includes 48 RT cores and 192 tensor cores, features that are entirely absent from the LX 7G100's specification list, where RT cores and tensor cores are marked null. This indicates the LX 7G100 may lack dedicated ray tracing and tensor acceleration hardware, or the data simply does not record them. The RTX 4000 SFF also supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

Clock behavior differs as well. The RTX 4000 SFF has a base clock of 720 MHz and a boost clock of 1560 MHz. The LX 7G100 has no base or boost clock recorded at all. Its memory clock is 2250 MHz with 18 Gbps effective speed, while the RTX 4000 SFF's memory clock is 1750 MHz with 14 Gbps effective. The RTX 4000 SFF is a 70 W card with no power connectors and a suggested PSU of 250 W. The LX 7G100 draws 225 W, requires a single 8-pin connector, and suggests a 550 W PSU. This power difference is substantial and likely reflects the LX 7G100's higher clocked memory and wider bus.

The physical footprint also differs sharply. The RTX 4000 SFF is 168 mm (6.6 inches) long and 69 mm (2.7 inches) high, making it a small form factor card. The LX 7G100 is 294 mm (11.6 inches) long, 120 mm (4.7 inches) high, and 49 mm (1.9 inches) wide, a much larger dual-slot card. Display outputs differ as well: the RTX 4000 SFF provides 4x mini-DisplayPort 1.4a, while the LX 7G100 provides 4x DisplayPort 1.4a.

Head-to-Head Benchmarks

The head-to-head benchmark comparison is empty. No direct benchmark results exist for the two cards against each other. The RTX 4000 SFF has two recorded benchmark scores: 124812 in Geekbench OpenCL and 109364 in Geekbench Vulkan. The LX 7G100 has no benchmark scores at all.

Despite the absence of direct head-to-head data, the RTX 4000 SFF's nearest rival comparisons provide context. Its average score of 117088 places it within a narrow band of competitors. The AMD Radeon PRO W7700 leads that group at 118976, just 1.6% ahead. The NVIDIA GB10 is nearly identical at 117393, only 0.3% ahead. The RTX 4000 SFF then leads the NVIDIA Tesla V100 SXM2 16 GB by 2.4% and the NVIDIA RTX A5500 Mobile by 2.8%. This positioning suggests the RTX 4000 SFF is a mid-pack performer among workstation and data center class GPUs, not a leader but not lagging significantly.

The LX 7G100's 50th percentile ranking, combined with an average score of 0, indicates it has no measurable standing in the database. Its specification sheet shows higher pixel rate (192.0 versus 99.84 GPixel/s), higher texture rate (384.0 versus 299.5 GTexel/s), and higher FP32 and FP16 throughput. These figures suggest the LX 7G100 could outperform the RTX 4000 SFF in compute-heavy tasks if its real-world performance matches its theoretical ratings. However, without benchmark data, that remains a hypothesis, not a finding.

The memory bandwidth difference is also notable. The LX 7G100's 432.0 GB/s is roughly 54% higher than the RTX 4000 SFF's 280.0 GB/s. This could translate to faster data movement in memory-bound workloads, but again, no recorded benchmark verifies this.

Where Each One Wins

Based strictly on recorded data, the NVIDIA RTX 4000 SFF Ada Generation wins in every area where measured performance exists. It has an average benchmark score of 117088, a 95th percentile ranking, and two individual benchmark results (124812 OpenCL, 109364 Vulkan). It also offers 20 GB of memory compared to the LX 7G100's 12 GB, which matters for large datasets that exceed 12 GB. Its 70 W TDP and lack of power connectors make it suitable for constrained power environments, and its 250 W suggested PSU requirement is far lower than the LX 7G100's 550 W. Its compact 168 mm length and 69 mm height enable installation in small form factor chassis.

The LX 7G100 wins on raw specification counts. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 are higher than the RTX 4000 SFF's 19.17 TFLOPS in both modes. Its 432.0 GB/s bandwidth, 192-bit bus, and 96 ROPs all exceed the RTX 4000 SFF's corresponding values. Its pixel rate of 192.0 GPixel/s is nearly double the RTX 4000 SFF's 99.84 GPixel/s, and its texture rate of 384.0 GTexel/s is higher than 299.5 GTexel/s. For workloads that are purely compute-bound and memory-bound, the LX 7G100's specification sheet suggests it could deliver more throughput. The LX 7G100 also has a later release date of June 17, 2026, versus March 20, 2023 for the RTX 4000 SFF.

The data does not support a clear use-case split because the LX 7G100 has no measured results. The RTX 4000 SFF is the only card with proven performance, so any workload requiring verified capability points to it. The LX 7G100's theoretical advantages in FP16, memory bandwidth, and pixel rate remain unconfirmed. Users who need ray tracing or tensor acceleration must choose the RTX 4000 SFF, as the LX 7G100 has no RT or tensor cores recorded. Users who need a smaller physical footprint and lower power draw also have only one viable option. The LX 7G100's larger size, higher power draw, and unverified performance make it a speculative choice at best.
