NVIDIA GeForce RTX 4090 D vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data does not include any direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 4090 D and the Lisuan Tech LX PRO. The database shows no wins for either product in paired testing, and the head-to-head benchmark table is empty. However, the individual performance records for each product provide a basis for comparison across different workload categories.

The RTX 4090 D delivers a 3DMark Steel Nomad DX12 score of 8587. The Lisuan Tech LX PRO has no recorded 3DMark scores, so no direct comparison exists in this specific test. The Geekbench OpenCL results show the RTX 4090 D scoring 278621, while the LX PRO has no Geekbench entries. Similarly, the Vulkan score for the RTX 4090 D is 246941, with no corresponding LX PRO result.

The average benchmark score for the RTX 4090 D is 178050. This places it in the 98th percentile among all GPUs in the database. The LX PRO has an average benchmark score of 0 and sits in the 50th percentile, indicating that the database currently contains no completed benchmark runs for this product.

Looking at the nearest rivals for the RTX 4090 D, the NVIDIA RTX PRO 5000 Blackwell averages 182109, which is 2.2% higher than the RTX 4090 D. The NVIDIA A100 SXM4 80 GB posts an average of 183725, 3.1% above the RTX 4090 D. The NVIDIA RTX 5000 Ada Generation reaches 184664, 3.6% higher, and the NVIDIA A100 SXM4 40 GB leads the group with 187147, 4.9% above the RTX 4090 D. These deltas show the RTX 4090 D trailing four professional-grade NVIDIA accelerators by modest single-digit margins.

The LX PRO has no nearest rivals listed, which means the database has not yet established comparative performance anchors for this product. With no benchmark scores recorded, the percentile ranking of 50 is a neutral placeholder rather than a performance verdict.

The FP32 compute figures tell a clear story. The RTX 4090 D delivers 73.54 TFLOPS of FP32 throughput, while the LX PRO provides 24.58 TFLOPS. That is approximately three times the raw single-precision compute capacity for the NVIDIA part. In FP16, the RTX 4090 D again lists 73.54 TFLOPS with a 1:1 ratio, whereas the LX PRO achieves 49.15 TFLOPS with a 2:1 ratio. The FP16 advantage for the RTX 4090 D is roughly 1.5 times.

Memory bandwidth separates the two further. The RTX 4090 D uses a 384-bit bus with GDDR6X memory to reach 1.01 TB/s of bandwidth. The LX PRO relies on a 192-bit bus with GDDR6 memory, capping out at 432.0 GB/s. The NVIDIA part offers more than twice the memory bandwidth of the Lisuan product.

Pixel and texture rates follow the same pattern. The RTX 4090 D achieves 443.5 GPixel/s and 1,149.1 GTexel/s. The LX PRO delivers 192.0 GPixel/s and 384.0 GTexel/s. The NVIDIA GPU leads by 2.3 times in pixel throughput and 3.0 times in texture throughput.

Architecture Differences

The two GPUs come from different architectural lineages. The RTX 4090 D uses the AD102 chip built on the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The LX PRO uses the 7G105 chip with an architecture labeled TrueGPU, manufactured on a 6 nm process, also at TSMC. The process node difference is one nanometer, which typically affects transistor density and power efficiency, though the LX PRO does not disclose transistor count or die size in the database.

The RTX 4090 D packs 76,300 million transistors on a 609 mm² die, yielding a transistor density of 125.3 million per square millimeter. The LX PRO has no transistor count, die size, or density figures recorded. This missing data limits architectural comparison to the features that are documented.

Shader resources differ substantially. The RTX 4090 D contains 14,592 shading units, 456 texture mapping units, and 176 render output units. The LX PRO has 6,144 shading units, 192 TMUs, and 96 ROPs. The NVIDIA GPU provides 2.4 times the shading units, 2.4 times the TMUs, and 1.8 times the ROPs.

Ray tracing and tensor hardware exist only on the RTX 4090 D. It has 114 RT cores and 456 tensor cores. The LX PRO lists no RT core or tensor core counts, indicating these features may be absent or undocumented. The RTX 4090 D also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX PRO supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, but only Vulkan 1.3, one minor revision behind.

Memory architecture differs in type and bus width. The RTX 4090 D uses 24 GB of GDDR6X on a 384-bit interface. The LX PRO uses 24 GB of GDDR6 on a 192-bit interface. Both have the same capacity, but the NVIDIA part has double the bus width and a faster memory type. The effective memory clock for the RTX 4090 D is 21 Gbps, while the LX PRO runs at 18 Gbps effective.

Power specifications show a significant gap. The RTX 4090 D has a TDP of 425 W and requires a suggested 800 W power supply. The LX PRO has a TDP of 225 W and a suggested 550 W power supply. The NVIDIA GPU consumes nearly double the power of the Lisuan part. Both use a single 16-pin power connector.

Physical dimensions also differ. The RTX 4090 D measures 304 mm in length, 137 mm in height, and 61 mm in width, occupying a triple-slot design. The LX PRO is 248 mm long, 118 mm high, and 48 mm wide, fitting into a dual-slot form factor. The NVIDIA card is longer, taller, and wider, which reflects its larger cooling requirement.

Display outputs vary. The RTX 4090 D provides 1x HDMI 2.1 and 3x DisplayPort 1.4a. The LX PRO provides 4x DisplayPort 1.4a, with no HDMI port. This matters for users who need HDMI connectivity, as the Lisuan card lacks it entirely.

The RTX 4090 D uses PCIe 4.0 x16, and the LX PRO also uses PCIe 4.0 x16. Both cards are compatible with the same motherboard interface standard.

Production status and release timing differ. The RTX 4090 D is end-of-life, with a release date of 2023-12-27. Its predecessor is the GeForce 30 series, and its successor is the GeForce 50 series. The LX PRO is active in production, with a release date of 2026-03-16. It has no listed predecessor or successor.

FAQ

The Verdict

The data supports a clear division of roles between these two GPUs. The RTX 4090 D is the higher-performing part across every measured metric in the database. It leads in FP32 compute by 3.0 times, FP16 compute by 1.5 times, pixel rate by 2.3 times, texture rate by 3.0 times, and memory bandwidth by 2.3 times. Its 98th percentile ranking among all GPUs confirms that it sits near the top of the performance distribution.

The LX PRO, with its 50th percentile ranking and no recorded benchmark scores, cannot be positioned as a performance competitor based on the current data. Its advantages are operational rather than performance-based. It draws 225 W versus 425 W, fits in a dual-slot form factor versus triple-slot, and measures 248 mm versus 304 mm in length. It also carries a suggested PSU of 550 W versus 800 W. These characteristics make it suitable for systems with tighter power budgets or smaller chassis.

The RTX 4090 D is the appropriate choice for workloads that demand maximum compute throughput, high memory bandwidth, or dedicated ray tracing and tensor hardware. Its 73.54 TFLOPS FP32 and 114 RT cores provide capabilities that the LX PRO does not match. The LX PRO, by contrast, offers 24 GB of memory with lower power draw, which could serve memory-intensive tasks that do not require extreme compute rates.

One notable consideration is the Vulkan API version. The RTX 4090 D supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. Applications built around Vulkan 1.4 features will run only on the NVIDIA card. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6, so compatibility for those APIs is equivalent.

The RTX 4090 D has a launch MSRP of 1,599 USD. The LX PRO has no launch MSRP recorded in the database.

For users who need HDMI output, the RTX 4090 D includes a single HDMI 2.1 port, while the LX PRO has none. For multi-display setups using DisplayPort only, the LX PRO provides four ports versus three on the RTX 4090 D.

The production status difference matters for availability. The RTX 4090 D is end-of-life, meaning supply may dwindle. The LX PRO is active, indicating ongoing availability. The RTX 4090 D also has a defined successor in the GeForce 50 series, while the LX PRO has no successor listed.

Given the absence of direct head-to-head benchmark data, the verdict rests on the isolated measurements. The RTX 4090 D dominates in raw performance metrics and feature set. The LX PRO offers a lower-power, smaller-footprint alternative with the same memory capacity. Neither card is ideal for every scenario, but the data clearly favors the RTX 4090 D for compute-heavy workloads and the LX PRO for power-constrained deployments.
