NVIDIA GeForce RTX 5090 D vs Lisuan Tech LX MAX Comparison

The NVIDIA GeForce RTX 5090 D and the Lisuan Tech LX MAX occupy opposite ends of the performance spectrum, yet both are active products in the database. The RTX 5090 D delivers top-tier throughput across every recorded benchmark, while the LX MAX posts no benchmark scores at all, making its comparison entirely dependent on architectural and specification data.

Where Each One Wins

The RTX 5090 D wins every category where measurements exist. Its recorded scores span ten tests, with an average benchmark score of 77,712 and a percentile rank of 92 among all GPUs. That places it in the upper tier of every graphics card in the database. The LX MAX has an empty benchmark array, an average score of 0, and a percentile rank of 50, which indicates a midpoint position based on its specifications rather than any measured performance.

The RTX 5090 D shows particular strength in compute-oriented workloads. Its Geekbench Vulkan score reaches 376,915, and its OpenCL score is 310,674. In the PassMark suite, the GPU compute result is 28,396, while the 3DMark Steel Nomad DX12 test returns 14,326. These numbers confirm a device built for heavy rendering and parallel computation.

The LX MAX, lacking any benchmark entries, cannot claim a single win. Its specification sheet suggests it is a mid-range part: 24.58 TFLOPS of FP32 throughput, 384.0 GTexel/s texture rate, and 192.0 GPixel/s pixel rate. Those figures are roughly one-quarter to one-third of the RTX 5090 D's corresponding outputs (104.8 TFLOPS FP32, 1,636.8 GTexel/s, 423.6 GPixel/s). The data does not show any workload where the LX MAX comes out ahead.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs. The comparison therefore relies on the RTX 5090 D's individual scores against the LX MAX's complete absence of measured data.

The RTX 5090 D's 3DMark Steel Nomad DX12 score of 14,326 represents its lowest recorded result among the ten tests, yet it still indicates a high-end part. The Geekbench Vulkan result of 376,915 is the strongest single score, followed by OpenCL at 310,674. PassMark G3D returns 44,065, while GPU compute hits 28,396. These four scores alone suggest a device that handles both graphics and general-purpose compute with ease.

The LX MAX has zero benchmark results in the database. Its specification-derived figures, such as 24.58 TFLOPS FP32 and 432.0 GB/s memory bandwidth, place it far below the RTX 5090 D's 104.8 TFLOPS and 1.79 TB/s. The nearest rivals to the RTX 5090 D, all within 2.4% of its average score, are mid-range mobile and datacenter parts. The LX MAX, with no scores, cannot be positioned against those rivals numerically.

The RTX 5090 D also shows consistency across legacy API tests. Its PassMark DirectX 9 score is 434, DirectX 10 is 231, DirectX 11 is 371, and DirectX 12 is 219. The G2D score of 1,487 reflects 2D graphics performance. These results, combined with the modern API scores, paint a picture of broad compatibility and strong output across multiple generations of graphics workloads.

Specification Differences

The two cards differ in nearly every measurable specification. The RTX 5090 D uses a 5 nm process node from TSMC, while the LX MAX uses a 6 nm node, also from TSMC. The RTX 5090 D's die size is 750 mm² with 92,200 million transistors and a transistor density of 122.9M per mm². The LX MAX's die size and transistor count are listed as unknown.

Memory is a major divergence. The RTX 5090 D has 32 GB of GDDR7 across a 512-bit bus, delivering 1.79 TB/s. The LX MAX has 12 GB of GDDR6 across a 192-bit bus, delivering 432.0 GB/s. The memory clock differs as well: 1750 MHz (28 Gbps effective) for the RTX 5090 D versus 2250 MHz (18 Gbps effective) for the LX MAX.

Compute unit counts show a wide gap. The RTX 5090 D has 21,760 shading units, 680 texture mapping units, and 176 ROPs. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The RTX 5090 D also has 170 RT cores and 680 tensor cores; the LX MAX lists neither.

Clock speeds are only recorded for the RTX 5090 D: 2017 MHz base and 2407 MHz boost. The LX MAX has no base or boost clock in the database. Power requirements differ sharply: the RTX 5090 D has a TDP of 575 W and a suggested PSU of 950 W, while the LX MAX has a TDP of 225 W and a suggested PSU of 550 W. Both use a single 16-pin power connector and are dual-slot cards.

The bus interface differs: PCIe 5.0 x16 for the RTX 5090 D versus PCIe 4.0 x16 for the LX MAX. Display outputs also differ: the RTX 5090 D has one HDMI 2.1b and three DisplayPort 2.1b outputs, while the LX MAX has four DisplayPort 1.4a outputs. Physical dimensions vary: the RTX 5090 D measures 304 mm by 137 mm by 48 mm, while the LX MAX measures 248 mm by 118 mm by 48 mm.

Architecture Differences

The RTX 5090 D is built on the Blackwell 2.0 architecture with the GB202 chip, part of the GeForce 50-series generation. Its predecessor is the GeForce 40 series, and its successor is the GeForce 60 series. The LX MAX uses the TrueGPU architecture with the 7G106 chip, part of the 7G100 generation, with no predecessor or successor listed.

The process nodes differ, as noted: 5 nm for the RTX 5090 D and 6 nm for the LX MAX, both from TSMC. The RTX 5090 D supports FP16 at a 1:1 ratio with FP32, meaning both hit 104.8 TFLOPS. The LX MAX supports FP16 at a 2:1 ratio, giving 49.15 TFLOPS FP16 versus 24.58 TFLOPS FP32. This indicates the LX MAX has dedicated FP16 throughput but lower overall compute density.

API support shows minor differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 5090 D supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. The RTX 5090 D's RT core count of 170 and tensor core count of 680 are absent from the LX MAX's record, suggesting either a different hardware approach or unrecorded specifications.

The RTX 5090 D's 92,200 million transistors on a 750 mm² die represent a massive chip. The LX MAX's transistor count is unknown, but its 6 nm process and smaller specifications imply a significantly smaller die. The LX MAX's 12 GB memory capacity and 192-bit bus are typical of a mid-range part, while the RTX 5090 D's 32 GB and 512-bit bus are flagship-tier.

The Verdict

The recorded data shows a complete mismatch. The RTX 5090 D delivers benchmark scores that place it in the 92nd percentile of all GPUs, with an average score of 77,712. Its nearest rivals are all within 2.4% of that average, and they are mid-range mobile and datacenter parts, not competing flagships. The LX MAX has no benchmark scores, an average score of 0, and a percentile rank of 50, which the database assigns based on its specification profile rather than any measured result.

For any workload that benefits from raw compute, memory bandwidth, or modern API features, the RTX 5090 D is the clear choice. Its 104.8 TFLOPS FP32, 1.79 TB/s memory bandwidth, and 32 GB of GDDR7 provide the headroom for demanding rendering, simulation, and AI tasks. The LX MAX's 24.58 TFLOPS FP32 and 432.0 GB/s bandwidth are roughly one-quarter and one-third of those figures, respectively.

The LX MAX does offer a lower power envelope: 225 W TDP with a 550 W suggested PSU, versus 575 W and 950 W for the RTX 5090 D. It also runs on PCIe 4.0 instead of PCIe 5.0 and uses GDDR6 instead of GDDR7. These differences suggest the LX MAX targets a different segment, but without benchmark data, the database cannot verify its actual performance.

The RTX 5090 D's release date of 2025-01-29 and its active production status indicate a current-generation flagship. The LX MAX's release date of 2026-03-16 is later, but its specifications align with a lower-tier product. The absence of a launch MSRP for the LX MAX prevents any price-based comparison, though the RTX 5090 D carries a launch MSRP of 2,299 USD.

The data implies that the RTX 5090 D is intended for users who prioritize maximum throughput and are willing to accommodate a 575 W TDP. The LX MAX appears suited for scenarios where lower power draw and physical size matter, but its lack of recorded benchmarks leaves its real-world capability unverified. Any decision between these two should be guided by the RTX 5090 D's measurable dominance across every test in the database.
