The Verdict

The data presents two cards with fundamentally different positions in the database. The NVIDIA GeForce RTX 4070 is an end-of-life product with extensive benchmark coverage, an average score of 37648, and an 81st percentile standing among all GPUs. Its nearest rivals include the AMD Radeon RX Vega 56 (0.4% slower), the NVIDIA Tesla P4 (0.1% slower), and the AMD Radeon PRO W6400 (1.3% slower), while the RTX 4080 Mobile sits 1.3% ahead. These margins are tight, indicating the RTX 4070 occupies a stable, well-characterized performance tier.

The Lisuan Tech LX 7G100 is an active product with no benchmark results recorded. Its percentile ranking of 50 and average score of 0 reflect the absence of measurement data rather than actual performance. Buyers cannot verify its real-world behavior from the database, making any selection decision speculative for this card.

For users prioritizing verified performance, the RTX 4070 is the only choice with recorded data. It shows consistent results across multiple tests: 3DMark Steel Nomad DX12 scores 3854, Geekbench OpenCL scores 154858, Geekbench Vulkan scores 174152, and PassMark G3D scores 26927. The LX 7G100 offers structural advantages in some specifications, such as higher pixel rate and more shading units, but without benchmark confirmation these remain theoretical.

The RTX 4070 suits users who need proven results, established API support including Vulkan 1.4, and a compact dual-slot design measuring 240 mm in length. The LX 7G100 targets those who prioritize newer production status, four DisplayPort outputs, and larger physical dimensions at 294 mm length, though its performance claims lack database verification.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the RTX 4070 and the LX 7G100. The RTX 4070 has ten recorded benchmark scores, while the LX 7G100 has none. This absence of comparative data means all performance assessments must rely on specification analysis and the RTX 4070's established scores.

In compute throughput, the RTX 4070 leads FP32 with 29.15 TFLOPS versus 24.58 TFLOPS, a 4.57 TFLOPS advantage. For FP16 workloads, the LX 7G100 reverses the situation with 49.15 TFLOPS versus the RTX 4070's 29.15 TFLOPS, a 20 TFLOPS lead. The LX 7G100 achieves this through a 2:1 FP16 ratio, while the RTX 4070 maintains a 1:1 ratio.

Memory bandwidth favors the RTX 4070 at 504.2 GB/s compared to 432.0 GB/s for the LX 7G100, a difference of 72.2 GB/s. Both cards use 12 GB capacity and 192-bit bus width, but the RTX 4070's GDDR6X memory operates at 21 Gbps effective versus 18 Gbps effective for the LX 7G100's GDDR6.

Texture processing favors the RTX 4070 with 455.4 GTexel/s against 384.0 GTexel/s, driven by 184 TMUs versus 192 TMUs but higher clock rates. Pixel processing favors the LX 7G100 with 192.0 GPixel/s versus 158.4 GPixel/s, supported by 96 ROPs compared to 64 ROPs on the RTX 4070.

The RTX 4070's benchmark results show its strongest performance in Geekbench Vulkan at 174152 and Geekbench OpenCL at 154858. PassMark G3D scores 26927, while PassMark G2D scores 1164. The 3DMark Steel Nomad DX12 test records 3854. PassMark legacy tests show 320 in DirectX 9, 244 in DirectX 11, 139 in DirectX 10, and 103 in DirectX 12. GPU compute in PassMark records 14720.

Without any benchmark data for the LX 7G100, the RTX 4070 wins all measured comparisons by default. Its specification advantages in FP32, texture rate, memory bandwidth, and API version coverage (Vulkan 1.4 versus 1.3) provide additional support. The LX 7G100 counters with FP16 throughput, pixel rate, shading unit count, and ROP count, though none of these advantages are validated by recorded test scores.

Specification Differences

The two cards diverge across nearly every major specification category. The RTX 4070 uses the AD104 chip built on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die. The LX 7G100 uses the 7G106 chip on a 6 nm process at TSMC, with transistor count and die size listed as unknown.

Clock speeds differ substantially. The RTX 4070 has a base clock of 1920 MHz and a boost clock of 2475 MHz. The LX 7G100 lists no base or boost clock in the database, only a memory clock of 2250 MHz with 18 Gbps effective. The RTX 4070's memory clock is 1313 MHz with 21 Gbps effective.

Memory type separates the cards: GDDR6X for the RTX 4070 versus GDDR6 for the LX 7G100. Both use 12 GB capacity and 192-bit bus width, but bandwidth differs at 504.2 GB/s versus 432.0 GB/s.

Compute unit counts favor the LX 7G100 in shading units (6144 versus 5888), TMUs (192 versus 184), and ROPs (96 versus 64). The RTX 4070 includes 46 RT cores and 184 tensor cores, while the LX 7G100 lists neither RT cores nor tensor cores in its specifications.

Power delivery differs: the RTX 4070 draws 200 W TDP with a 1x 16-pin connector, while the LX 7G100 draws 225 W TDP with a 1x 8-pin connector. Both recommend a 550 W power supply.

Physical dimensions favor the RTX 4070 for compact builds: 240 mm length, 110 mm height, 40 mm width. The LX 7G100 is larger at 294 mm length, 120 mm height, 49 mm width. Both are dual-slot cards.

Display outputs differ: the RTX 4070 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the LX 7G100 offers 4x DisplayPort 1.4a with no HDMI. Both use PCIe 4.0 x16 interfaces.

API support is nearly identical with DirectX 12 Ultimate (12_2) and OpenGL 4.6 on both. Vulkan support differs: the RTX 4070 supports Vulkan 1.4, the LX 7G100 supports Vulkan 1.3.

Production status separates the cards: the RTX 4070 is end-of-life, released in April 2023 with a predecessor in GeForce 30 and successor in GeForce 50. The LX 7G100 is active, released in June 2026, with no predecessor or successor listed.

Architecture Differences

The architectural divide between these two cards is significant. The RTX 4070 uses NVIDIA's Ada Lovelace architecture on a 5 nm TSMC process, featuring 35,800 million transistors on a 294 mm² die. The LX 7G100 uses a "TrueGPU" architecture on a 6 nm TSMC process, with transistor count and die size unknown.

The RTX 4070 integrates dedicated ray tracing cores (46) and tensor cores (184), enabling hardware-accelerated ray tracing and AI workloads. The LX 7G100 lists no RT cores or tensor cores, suggesting either their absence or undisclosed presence. This distinction matters for DirectX 12 Ultimate workloads where ray tracing features are exposed.

The FP16 execution ratio reveals a core design difference. The RTX 4070 processes FP16 at a 1:1 ratio with FP32, delivering 29.15 TFLOPS in both. The LX 7G100 uses a 2:1 ratio, achieving 49.15 TFLOPS FP16 against 24.58 TFLOPS FP32. This indicates the LX 7G100's shader architecture can double FP16 throughput, a design choice suited for certain compute workloads.

Shader organization differs: the LX 7G100 packs 6144 shading units, 192 TMUs, and 96 ROPs, while the RTX 4070 uses 5888 shading units, 184 TMUs, and 64 ROPs. The LX 7G100's higher ROP count directly explains its pixel rate advantage of 192.0 GPixel/s versus 158.4 GPixel/s. The RTX 4070's higher clock speeds compensate for fewer units in texture rate, achieving 455.4 GTexel/s against 384.0 GTexel/s.

The RTX 4070's memory subsystem uses GDDR6X, a higher-bandwidth memory type that delivers 504.2 GB/s from a 192-bit interface. The LX 7G100 uses standard GDDR6 at 432.0 GB/s over the same bus width. The 21 Gbps effective memory speed of the RTX 4070 versus 18 Gbps on the LX 7G100 accounts for the bandwidth gap.

Production lifecycle differs markedly. The RTX 4070 belongs to the GeForce 40-series generation, with a predecessor in GeForce 30 and successor in GeForce 50, and is marked end-of-life. The LX 7G100 is an active product from the 7G100 generation with no lineage data. This positions the RTX 4070 as a mature, well-tested design and the LX 7G100 as a newer entrant without historical context.

The RTX 4070 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4070 includes HDMI 2.1 output, which the LX 7G100 lacks entirely. The LX 7G100 compensates with four DisplayPort outputs versus three on the RTX 4070.

Power efficiency favors the RTX 4070 based on available data: 200 W TDP versus 225 W TDP, combined with higher FP32 throughput. The LX 7G100's larger physical footprint (294 mm versus 240 mm length) suggests a more substantial cooling solution, though both are dual-slot designs.
