NVIDIA GeForce RTX 4070 Mobile vs Lisuan Tech LX MAX Comparison

The Verdict

The NVIDIA GeForce RTX 4070 Mobile and Lisuan Tech LX MAX occupy completely different positions in the database. The RTX 4070 Mobile is a proven, shipping product with an active production status and a 73rd percentile ranking among all GPUs. Its average benchmark score of 27,435 places it in a tight cluster with the AMD Radeon RX 6700 XT (27,425, 0% delta) and the NVIDIA GeForce RTX 3090 (27,565, -0.5% delta). The Lisuan Tech LX MAX, by contrast, has no recorded benchmarks, an average score of zero, and sits at the 50th percentile by default. It is a future release dated 2026-03-16 with an active production status, but no measured performance data exists in the database.

The RTX 4070 Mobile is the only choice for anyone who needs verified performance today. Its benchmark results span multiple API generations, from DirectX 9 to DirectX 12, plus OpenCL, Vulkan, and compute workloads. The LX MAX cannot be evaluated on performance because no test results are recorded. The data shows the RTX 4070 Mobile delivers a balanced mobile GPU package with 8 GB of GDDR6 memory, a 128-bit bus, and 256.0 GB/s of bandwidth, all within a 115 W TDP. The LX MAX presents a larger desktop-oriented specification sheet: 12 GB of GDDR6, a 192-bit bus, 432.0 GB/s bandwidth, and a 225 W TDP, but without benchmark confirmation.

For a builder needing a working GPU now, the RTX 4070 Mobile is the only option with measurable results. For someone evaluating the LX MAX, the database offers specifications only, and every purchasing decision must account for the absence of test data. The RTX 4070 Mobile matches or slightly trails the RTX 3090 in average score (by 0.5%) while leading the RTX PRO 4000 Blackwell by 1.1%. These rival comparisons provide context for the mobile part, but no such context exists for the LX MAX.

Where Each One Wins

The RTX 4070 Mobile wins in every category where measured performance exists. Its Geekbench OpenCL score of 109,197 and Vulkan score of 108,367 demonstrate strong compute and graphics API performance. PassMark results show a spread across DirectX versions: 116 in DirectX 10, 179 in DirectX 11, 85 in DirectX 12, and 223 in DirectX 9. The G2D score of 763 and G3D score of 19,587 indicate the part handles 2D tasks comfortably and delivers substantial 3D capability. GPU compute score sits at 8,399.

The LX MAX wins on paper specifications. Its 24.58 TFLOPS FP32 throughput exceeds the RTX 4070 Mobile's 15.62 TFLOPS by a wide margin. FP16 performance doubles to 49.15 TFLOPS with a 2:1 ratio, while the RTX 4070 Mobile offers 15.62 TFLOPS at 1:1. The LX MAX also claims higher pixel rate (192.0 GPixel/s versus 81.36 GPixel/s) and texture rate (384.0 GTexel/s versus 244.1 GTexel/s). Memory bandwidth favors the LX MAX at 432.0 GB/s versus 256.0 GB/s. These are specification advantages, not measured wins. The database records no benchmark victories for either part in head-to-head testing, as the head-to-head benchmark array is empty.

The use-case split is clear: the RTX 4070 Mobile serves users who need a proven, power-efficient mobile GPU with broad API support and verified performance. The LX MAX targets users who prioritize raw specification headroom, larger memory capacity, and a desktop form factor, provided they accept the absence of any benchmark validation.

Architecture Differences

The RTX 4070 Mobile uses the AD106 chip built on NVIDIA's Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. The die measures 188 mm² and contains 22,900 million transistors, yielding a density of 121.8 million transistors per square millimeter. The LX MAX uses a 7G106 chip with a TrueGPU architecture, also fabricated by TSMC but on a 6 nm process. Transistor count and die size are listed as unknown, with no density figure recorded.

The RTX 4070 Mobile integrates 4,608 shading units, 144 texture mapping units, and 48 raster output pipelines. It includes 36 ray tracing cores and 144 tensor cores, reflecting NVIDIA's dedicated hardware for RT and AI workloads. The LX MAX lists 6,144 shading units, 192 TMUs, and 96 ROPs, but provides no ray tracing or tensor core counts. The LX MAX has more of every compute unit category that is specified, yet lacks the specialized RT and tensor hardware that the NVIDIA part carries.

Clock behavior differs substantially. The RTX 4070 Mobile has a base clock of 1395 MHz and a boost clock of 1695 MHz. The LX MAX does not list base or boost clocks, only a memory clock of 2250 MHz with 18 Gbps effective data rate. The RTX 4070 Mobile memory runs at 2000 MHz with 16 Gbps effective. Both use GDDR6 memory, but the LX MAX doubles the bus width to 192 bits versus 128 bits, and memory capacity rises from 8 GB to 12 GB.

The RTX 4070 Mobile is an integrated graphics package (IGP) with no slot width, no power connectors, and a PCIe 4.0 x8 bus interface. Display outputs are portable device dependent. The LX MAX is a dual-slot desktop card measuring 248 mm in length, 118 mm in height, and 48 mm in width. It uses a single 16-pin power connector, requires a 550 W suggested PSU, and offers four DisplayPort 1.4a outputs. The LX MAX uses PCIe 4.0 x16. API support matches for DirectX 12 Ultimate (12_2) and OpenGL 4.6, but Vulkan differs: the RTX 4070 Mobile supports Vulkan 1.4 while the LX MAX supports Vulkan 1.3.

Power envelopes diverge sharply. The RTX 4070 Mobile carries a 115 W TDP, while the LX MAX is rated at 225 W. The RTX 4070 Mobile belongs to the GeForce 40 Mobile generation and lists the GeForce 30 Mobile as predecessor and GeForce 50 Mobile as successor. The LX MAX has no recorded predecessor or successor.

Head-to-Head Benchmarks

The head-to-head benchmark array is empty, meaning no direct comparison tests exist between these two GPUs in the database. The RTX 4070 Mobile's individual benchmark results provide the only measurable performance data. Its Geekbench OpenCL score of 109,197 and Vulkan score of 108,367 show strong cross-API compute performance. The PassMark suite reveals an uneven profile across DirectX versions: DirectX 9 scores highest at 223, DirectX 11 at 179, DirectX 10 at 116, and DirectX 12 at 85. This pattern suggests the architecture performs best in legacy DirectX workloads while newer API paths remain less optimized in the recorded tests.

The PassMark G3D score of 19,587 is the primary 3D gaming indicator, while the GPU compute score of 8,399 covers non-graphics workloads. The G2D score of 763 confirms solid 2D performance. The average benchmark score of 27,435 aggregates these results into a single figure that the database uses for percentile ranking and rival comparisons. Against the RTX 3090, the RTX 4070 Mobile trails by just 0.5%, a remarkable result for a mobile part versus a desktop flagship. Against the RX 6700 XT, the scores are identical at a 0% delta.

The LX MAX has no benchmark entries. Its specification-derived performance claims remain unverified. The FP32 throughput of 24.58 TFLOPS and FP16 throughput of 49.15 TFLOPS are theoretical maximums based on shading unit count and clock assumptions, but no clock speeds are recorded, so even these figures carry uncertainty. The pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s similarly derive from unconfirmed specifications. Without recorded test scores, the LX MAX cannot be positioned against any rival in the database.

For the RTX 4070 Mobile, the nearest rival comparisons offer the clearest performance interpretation. The 0% delta versus the RX 6700 XT indicates parity in average score. The -0.5% delta versus the RTX 3090 shows near-parity with a much larger desktop card. The 1.1% lead over the RTX PRO 4000 Blackwell and the 1.5% deficit to the Radeon Pro Vega 20 bracket the mobile part within a narrow performance band. These deltas are small, suggesting the RTX 4070 Mobile delivers consistent, predictable performance relative to its desktop contemporaries.

The two GPUs share the same TSMC foundry and GDDR6 memory type, plus identical DirectX 12 Ultimate (12_2) and OpenGL 4.6 support. Every other specification differs. The LX MAX leads in raw compute resources, memory capacity, bandwidth, and clock rates. The RTX 4070 Mobile leads in process node efficiency, ray tracing and tensor hardware, Vulkan API version, and power efficiency. The RTX 4070 Mobile carries a lower TDP by 110 W and requires no power connectors, while the LX MAX needs a 16-pin connector and a 550 W PSU. The form factors are incompatible: one is an IGP for portable devices, the other a dual-slot desktop expansion card. The release dates are separated by more than three years, with the LX MAX slated for 2026-03-16.
