NVIDIA GeForce RTX 5070 vs Lisuan Tech LX 7G100 Comparison

The Verdict

The recorded data presents an unusual comparison. The NVIDIA GeForce RTX 5070 is a fully characterized product with a substantial set of benchmark scores, while the Lisuan Tech LX 7G100 has no recorded benchmark results in the database. The RTX 5070 sits at the 82nd percentile among all GPUs, with an average benchmark score of 40,377. The LX 7G100 holds a 50th percentile ranking, but its average benchmark score is listed as 0, and no head-to-head tests exist between the two.

For any workload where measured performance matters, the RTX 5070 is the only option with verifiable data. Its nearest rivals in the database include the AMD Radeon Pro 580 (average score 40,318, a 0.1% difference) and the AMD Radeon Pro 5300 (average score 40,870, a -1.2% difference), placing it in a tightly contested professional-class performance band. The LX 7G100 cannot be positioned against these numbers because no scores were recorded for it.

The decision splits along data availability. The RTX 5070 is a proven entity with measurable results across DirectX, OpenCL, Vulkan, and compute workloads. The LX 7G100 is an active product in the database with architectural specifications but zero benchmark presence. Users requiring validated performance data must choose the RTX 5070. Users evaluating the LX 7G100 would be making a selection based solely on its specification sheet, with no empirical evidence to confirm its behavior.

Architecture Differences

The two GPUs diverge at the foundational level. The RTX 5070 uses the GB205 chip built on NVIDIA's Blackwell 2.0 architecture, manufactured on a 5 nm process at TSMC. The LX 7G100 uses the 7G106 chip under an architecture called TrueGPU, manufactured on a 6 nm process, also at TSMC. The RTX 5070 carries 31,100 million transistors on a 263 mm² die, giving it a transistor density of 118.3M per mm². The LX 7G100 has unknown transistor counts and die size in the database.

Both cards feature 12 GB of memory and a 192-bit bus, but the memory technology differs. The RTX 5070 uses GDDR7 at 1750 MHz with 28 Gbps effective, producing 672.0 GB/s of bandwidth. The LX 7G100 uses GDDR6 at 2250 MHz with 18 Gbps effective, yielding 432.0 GB/s. That represents a substantial bandwidth advantage for the RTX 5070, roughly 55% higher.

Compute resources show both similarities and differences. Both GPUs have 6,144 shading units and 192 texture mapping units. The RTX 5070 has 80 render output units, while the LX 7G100 has 96, a 20% higher count. The RTX 5070 includes 48 ray tracing cores and 192 tensor cores. The LX 7G100 lists no ray tracing or tensor core counts in the database, suggesting either absence or unspecified configuration.

Clock behavior differs significantly. The RTX 5070 has a base clock of 2325 MHz and a boost clock of 2512 MHz. The LX 7G100 has no base or boost clocks recorded. The LX 7G100's memory clock is higher at 2250 MHz versus 1750 MHz, but the effective data rate is lower due to the GDDR6 versus GDDR7 difference.

Pixel and texture rates tell a story of trade-offs. The RTX 5070 achieves 201.0 GPixel/s and 482.3 GTexel/s. The LX 7G100 achieves 192.0 GPixel/s and 384.0 GTexel/s. The RTX 5070 leads in both metrics, but the gap is larger in texture rate (about 25%) than in pixel rate (about 5%).

Floating-point performance diverges by precision. The RTX 5070 delivers 30.87 TFLOPS for both FP32 and FP16, a 1:1 ratio. The LX 7G100 delivers 24.58 TFLOPS for FP32 but 49.15 TFLOPS for FP16, a 2:1 ratio. The LX 7G100's FP16 output is substantially higher, while the RTX 5070 holds the FP32 advantage.

Power and connectivity also differ. The RTX 5070 has a 250 W TDP and requires a 600 W suggested PSU, using a single 16-pin connector. The LX 7G100 has a 225 W TDP and a 550 W suggested PSU, using a single 8-pin connector. Both are dual-slot cards. The RTX 5070 uses PCIe 5.0 x16, while the LX 7G100 uses PCIe 4.0 x16. Display outputs differ as well: the RTX 5070 has one HDMI 2.1b and three DisplayPort 2.1b outputs, while the LX 7G100 has four DisplayPort 1.4a outputs.

API support is nearly matched. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5070 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database for these two GPUs. The head-to-head test list is empty, and the win counts for both sides are zero. This absence of comparative data is itself a significant finding.

The RTX 5070 has individual benchmark scores that stand on their own. In 3DMark Steel Nomad DX12, it scores 5,077. In Geekbench OpenCL, it scores 172,660, and in Geekbench Vulkan, it scores 178,923. Passmark results show a G3D score of 29,137, a GPU compute score of 15,787, and a G2D score of 1,305. DirectX-specific Passmark tests score 320 for DirectX 9, 277 for DirectX 11, 180 for DirectX 10, and 108 for DirectX 12.

The LX 7G100 has no recorded scores in any of these tests. Its benchmark array is empty. The database shows an average benchmark score of 0, which is consistent with having no measurements to aggregate.

Relative positioning comes from the RTX 5070's nearest rivals. Its average score of 40,377 is 0.1% above the AMD Radeon Pro 580 (40,318) and 0.8% above the AMD Radeon Pro WX 7100 (40,063). It is 1.2% below the AMD Radeon Pro 5300 (40,870) and 2% above the NVIDIA RTX A500 Mobile (39,568). These deltas place the RTX 5070 in a narrow performance cluster where small percentage swings separate products.

The LX 7G100 has no nearest rivals listed. Without benchmark data, the database cannot compute comparative deltas against other GPUs. Its 50th percentile ranking appears to be a default or placeholder position rather than a derived statistic.

Where Each One Wins

The RTX 5070 wins in every category where measured data exists. Its memory bandwidth of 672.0 GB/s is approximately 55% higher than the LX 7G100's 432.0 GB/s. Its FP32 throughput of 30.87 TFLOPS exceeds the LX 7G100's 24.58 TFLOPS by about 25%. Its texture rate of 482.3 GTexel/s beats 384.0 GTexel/s by roughly 25%. Its pixel rate of 201.0 GPixel/s edges out 192.0 GPixel/s. It also carries dedicated ray tracing cores and tensor cores, which the LX 7G100 does not list.

The LX 7G100 wins in specific specification categories. Its FP16 performance of 49.15 TFLOPS is about 59% higher than the RTX 5070's 30.87 TFLOPS. Its 96 render output units exceed the RTX 5070's 80. Its memory clock of 2250 MHz is higher than the RTX 5070's 1750 MHz, though the effective data rate is lower due to the older GDDR6 standard. It draws less power, with a 225 W TDP versus 250 W, and requires a 550 W PSU rather than 600 W.

The LX 7G100's FP16 advantage suggests a design oriented toward workloads that leverage half-precision computation. The 2:1 FP16 to FP32 ratio indicates a different compute philosophy than the RTX 5070's 1:1 ratio. Applications that can utilize FP16 throughput would see a theoretical advantage on the LX 7G100, while FP32-heavy workloads favor the RTX 5070.

The RTX 5070's newer process node, higher memory bandwidth, and PCIe 5.0 interface position it as the more forward-looking design. The LX 7G100's 6 nm node and PCIe 4.0 interface align with an earlier or more conservative platform. The display output difference is also notable: the RTX 5070 supports DisplayPort 2.1b, while the LX 7G100 maxes out at DisplayPort 1.4a.

The decisive factor remains benchmark presence. The RTX 5070 has ten recorded tests spanning multiple API generations and compute paradigms. The LX 7G100 has zero. In the database, a GPU with no recorded performance data cannot establish wins in any measured category. The LX 7G100's specification-level wins are real but unverified in practice.
