NVIDIA GeForce RTX 4090 D vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two cards, though direct head-to-head benchmark results are not available in the database. Instead, the comparison relies on each card’s average benchmark score, percentile ranking, and the nearest rival data for the RTX 4090 D.

The NVIDIA GeForce RTX 4090 D delivers an average benchmark score of 178,050 across its three recorded tests: 3DMark Steel Nomad DX12 (8,587), Geekbench OpenCL (278,621), and Geekbench Vulkan (246,941). This places it in the 98th percentile of all GPUs, meaning it outperforms 98% of the database’s recorded graphics cards. Its nearest rivals in the database are the NVIDIA RTX PRO 5000 Blackwell (average score 182,109, which is 2.2% higher), the NVIDIA A100 SXM4 80 GB (183,725, 3.1% higher), the NVIDIA RTX 5000 Ada Generation (184,664, 3.6% higher), and the NVIDIA A100 SXM4 40 GB (187,147, 4.9% higher). In other words, the RTX 4090 D trails those four cards by margins ranging from 2.2% to 4.9%, but it still sits far above the median GPU in the database.

The Lisuan Tech LX MAX, by contrast, has no recorded benchmark scores in the database. Its average benchmark score is listed as 0, and it has no nearest rivals. Its percentile ranking is 50, which indicates it sits at the median of all GPUs in the database, but that figure is not derived from any actual benchmark runs. The absence of test data means the LX MAX cannot be directly compared to the RTX 4090 D on the same workloads. What the database does provide is the LX MAX’s theoretical compute specifications, which offer a basis for estimating relative performance.

On raw compute metrics, the RTX 4090 D’s FP32 throughput is 73.54 TFLOPS, while the LX MAX delivers 24.58 TFLOPS. That is a 49.0 TFLOPS gap, meaning the RTX 4090 D has roughly three times the single-precision floating-point throughput. For FP16, the RTX 4090 D sustains 73.54 TFLOPS (1:1 ratio with FP32), whereas the LX MAX reaches 49.15 TFLOPS (2:1 ratio). Here the difference narrows: the RTX 4090 D is still ahead by 24.39 TFLOPS, but the LX MAX’s 2:1 FP16 ratio gives it proportionally more half-precision capability relative to its FP32 output. Texture and pixel rates follow the same pattern. The RTX 4090 D outputs 1,149.1 GTexel/s and 443.5 GPixel/s, while the LX MAX manages 384.0 GTexel/s and 192.0 GPixel/s. The RTX 4090 D is roughly three times faster in texture fill and about 2.3 times faster in pixel fill.

Memory bandwidth shows a smaller but still significant gap. The RTX 4090 D uses 24 GB of GDDR6X on a 384-bit bus, delivering 1.01 TB/s. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. That is a 578 GB/s difference, meaning the RTX 4090 D has about 2.34 times the memory bandwidth. The LX MAX does have a higher memory clock in raw terms: its memory runs at 2250 MHz (18 Gbps effective) versus the RTX 4090 D’s 1313 MHz (21 Gbps effective). But the wider bus and newer memory type on the RTX 4090 D overcome that clock advantage.

In terms of raw shading resources, the RTX 4090 D features 14,592 shading units, 456 texture mapping units, and 176 ROPs. The LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The RTX 4090 D holds a 2.4-to-1 advantage in shading units, a 2.4-to-1 edge in TMUs, and a 1.8-to-1 lead in ROPs. The RTX 4090 D also includes 114 RT cores and 456 tensor cores; the LX MAX lists no RT cores or tensor cores in the database, indicating those features are either absent or not specified. For ray tracing and AI-accelerated workloads, the RTX 4090 D has a decisive structural advantage.

Power consumption and physical design differ substantially. The RTX 4090 D has a TDP of 425 W and requires a suggested power supply of 800 W. The LX MAX has a TDP of 225 W and a suggested PSU of 550 W. The RTX 4090 D is a triple-slot card measuring 304 mm in length, 137 mm in height, and 61 mm in width. The LX MAX is a dual-slot card at 248 mm by 118 mm by 48 mm. The RTX 4090 D is physically larger in every dimension and draws nearly double the power. The LX MAX’s lower power envelope means it will produce less heat and may fit in more compact systems, but that comes with the compute trade-offs described above.

Architecture Differences

The two cards come from different architectural lineages. The RTX 4090 D uses NVIDIA’s Ada Lovelace architecture, built on TSMC’s 5 nm process. Its chip, the AD102, contains 76,300 million transistors on a 609 mm² die, yielding a transistor density of 125.3 million per mm². The LX MAX uses an architecture called TrueGPU, fabricated on TSMC’s 6 nm process, with the chip designated 7G106. The database does not record transistor count, die size, or transistor density for the LX MAX, so those metrics are unavailable. The process node difference is one nanometer, which typically translates to some efficiency advantage for the smaller node, but without transistor data, the architectural comparison is limited.

The RTX 4090 D is part of the GeForce 40 series, with a generation labeled GeForce 40. Its predecessor is the GeForce 30 series, and its successor is the GeForce 50 series. The LX MAX belongs to the 7G100 generation and has no recorded predecessor or successor. The RTX 4090 D’s production status is end-of-life, while the LX MAX is marked as active.

Memory architecture differs beyond capacity and bandwidth. The RTX 4090 D uses GDDR6X, which is a higher-bandwidth memory type than the LX MAX’s GDDR6. The bus widths are 384-bit versus 192-bit. The RTX 4090 D’s memory clock is 1313 MHz with 21 Gbps effective data rate; the LX MAX’s memory clock is 2250 MHz with 18 Gbps effective. Despite the LX MAX’s higher base clock, the RTX 4090 D’s wider bus produces far more usable bandwidth.

Compute feature sets diverge in several key areas. The RTX 4090 D has dedicated ray tracing cores (114) and tensor cores (456), which accelerate RT and AI workloads. The LX MAX lists no such units. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4090 D supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. That places the RTX 4090 D one minor version ahead in Vulkan compatibility.

The FP16 ratio is another architectural distinction. The RTX 4090 D runs FP16 at a 1:1 ratio with FP32, meaning it does not double throughput for half-precision. The LX MAX uses a 2:1 ratio, so its FP16 output is twice its FP32 output. This suggests the LX MAX is designed for workloads that benefit from half-precision math, though its absolute FP16 peak (49.15 TFLOPS) is still lower than the RTX 4090 D’s 73.54 TFLOPS.

Display outputs differ as well. The RTX 4090 D offers 1x HDMI 2.1 and 3x DisplayPort 1.4a. The LX MAX provides 4x DisplayPort 1.4a with no HDMI port. Both use PCIe 4.0 x16 for the host interface. Power connectors are identical: a single 16-pin connector on each card.

The Verdict

The data supports a clear differentiation. The RTX 4090 D is a high-end card with a 98th percentile ranking, a substantial average benchmark score of 178,050, and a feature set that includes ray tracing cores, tensor cores, and 24 GB of GDDR6X memory. The LX MAX has no benchmark data, sits at the 50th percentile, and offers half the memory, fewer shading units, and no ray tracing or tensor cores. Any workload that relies on ray tracing, AI acceleration, high FP32 throughput, or large memory capacity will favor the RTX 4090 D.

The LX MAX’s advantages are limited to lower power draw (225 W versus 425 W), a smaller physical footprint (dual-slot versus triple-slot, shorter length), and a 2:1 FP16 ratio that gives it proportionally stronger half-precision performance, though still below the RTX 4090 D in absolute terms. The LX MAX also has four DisplayPort outputs versus the RTX 4090 D’s three, which may matter for multi-monitor setups without HDMI.

For users who need maximum compute performance in the database’s recorded metrics, the RTX 4090 D is the clear choice. Its average benchmark score is not directly comparable to the LX MAX because the latter has no scores, but the RTX 4090 D’s nearest rivals all score within 2.2% to 4.9% higher, placing it in the upper tier of the database. The LX MAX, with no recorded scores, cannot claim any measured performance advantage.

For users prioritizing power efficiency and compactness, the LX MAX presents a lower-power alternative. Its 225 W TDP and dual-slot design allow for simpler cooling and smaller cases, and its suggested PSU of 550 W is 250 W lower than the RTX 4090 D’s 800 W requirement. But those physical benefits come with a massive compute reduction: 24.58 TFLOPS FP32 versus 73.54 TFLOPS, and 432.0 GB/s memory bandwidth versus 1.01 TB/s.

The production status also matters. The RTX 4090 D is end-of-life, meaning it is no longer in active production. The LX MAX is active, so it remains available. However, the RTX 4090 D has a recorded launch MSRP of 1,599 USD, while the LX MAX has no recorded launch price.
