NVIDIA GeForce RTX 5090 D vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between the NVIDIA GeForce RTX 5090 D and the Lisuan Tech LX ULTRA are not available in the recorded data. The database shows no shared benchmark entries for these two products, which means a test-by-test comparison cannot be constructed from measured scores. Instead, the analysis must rely on the aggregate performance indicators and the available specification-level data.

The NVIDIA GeForce RTX 5090 D has a recorded average benchmark score of 77,712 across its ten benchmark runs. Its percentile ranking places it at the 92nd percentile among all GPUs in the database. The Lisuan Tech LX ULTRA, by contrast, holds a 50th percentile ranking and an average benchmark score of zero, indicating that no completed benchmark results have been logged for it. This absence of measured data for the LX ULTRA means that the RTX 5090 D stands as the only one of the two with a verified performance profile.

Looking at the RTX 5090 D's nearest rivals in the database, the AMD Radeon RX 6650M XT averages 76,904 points, which is 1.1% behind the RTX 5090 D. The AMD Radeon RX 6850M XT sits 1.6% ahead with an average of 78,940 points. The NVIDIA Tesla P100 PCIe 12 GB and 16 GB variants trail by 2.1% and 2.4%, respectively, with average scores of 79,396 and 79,605. These deltas place the RTX 5090 D in a tight competitive band, slightly above the RX 6650M XT but below the RX 6850M XT and both Tesla P100 models.

The RTX 5090 D's individual benchmark scores reveal its strongest areas. In Geekbench Vulkan, it records 376,915 points. In Geekbench OpenCL, it reaches 310,674. The 3DMark Steel Nomad DX12 test yields 14,326 points. Passmark G3D shows 44,065 points, and Passmark GPU Compute reports 28,396 points. Legacy DirectX tests show lower scores: 434 in DirectX 9, 371 in DirectX 11, 231 in DirectX 10, and 219 in DirectX 12. Passmark G2D measures 1,487 points. These figures provide the only concrete performance data available for either product.

The LX ULTRA's lack of benchmark entries means that no wins can be attributed to it in any test category. The RTX 5090 D therefore holds every recorded performance advantage by default, though this is a consequence of missing data rather than direct comparison.

Where Each One Wins

The RTX 5090 D wins in every measurable category, because the LX ULTRA has no recorded benchmark results. In compute workloads, the RTX 5090 D delivers 104.8 TFLOPS FP32 and 104.8 TFLOPS FP16 (1:1 ratio). The LX ULTRA provides 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). The RTX 5090 D's FP32 throughput is more than four times higher, and its FP16 output is roughly double.

In rasterization throughput, the RTX 5090 D reaches 1,636.8 GTexel/s texture rate and 423.6 GPixel/s pixel rate. The LX ULTRA records 384.0 GTexel/s and 192.0 GPixel/s. The RTX 5090 D leads by a wide margin in both.

Memory capacity favors the RTX 5090 D at 32 GB of GDDR7 across a 512-bit bus. The LX ULTRA uses 24 GB of GDDR6 on a 192-bit bus. The RTX 5090 D also has a higher memory clock at 1750 MHz (28 Gbps effective) versus 2250 MHz (18 Gbps effective) for the LX ULTRA. The effective bandwidth difference is decisive: 1.79 TB/s versus 432.0 GB/s.

The RTX 5090 D includes ray tracing cores (170) and tensor cores (680). The LX ULTRA lists no ray tracing cores and no tensor cores in the database. For workloads that rely on those units, the RTX 5090 D is the only option with dedicated hardware.

Specification Differences

The RTX 5090 D uses the GB202 chip with Blackwell 2.0 architecture on a 5 nm process from TSMC. It contains 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9M per mm². The LX ULTRA uses the 7G105 chip with TrueGPU architecture on a 6 nm process from TSMC. Its transistor count, die size, and transistor density are recorded as unknown.

The RTX 5090 D has 21,760 shading units, 680 TMUs, and 176 ROPs. The LX ULTRA has 6,144 shading units, 192 TMUs, and 96 ROPs. The RTX 5090 D's shading unit count is more than triple, its TMU count is more than triple, and its ROP count is nearly double.

Clock speeds differ significantly. The RTX 5090 D has a base clock of 2017 MHz and a boost clock of 2407 MHz. The LX ULTRA has no base or boost clock recorded in the database.

Memory configuration differs across every field. The RTX 5090 D uses 32 GB of GDDR7 with a 512-bit bus and 1.79 TB/s bandwidth. The LX ULTRA uses 24 GB of GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth.

Power requirements diverge sharply. The RTX 5090 D has a TDP of 575 W and a suggested PSU of 950 W. The LX ULTRA has a TDP of 225 W and a suggested PSU of 550 W. Both use a single 16-pin power connector and dual-slot cooling.

The bus interface differs: PCIe 5.0 x16 for the RTX 5090 D versus PCIe 4.0 x16 for the LX ULTRA. Display outputs also differ: the RTX 5090 D provides 1x HDMI 2.1b and 3x DisplayPort 2.1b, while the LX ULTRA provides 4x DisplayPort 1.4a.

Physical dimensions vary. The RTX 5090 D measures 304 mm in length, 137 mm in height, and 48 mm in width. The LX ULTRA is smaller at 268 mm, 112 mm, and 40 mm.

Architecture Differences

The RTX 5090 D is built on Blackwell 2.0, a generation marked by a 5 nm TSMC process. The LX ULTRA uses TrueGPU architecture on a 6 nm TSMC process. The process node difference is one nanometer, but the architectural divergence is substantial.

The RTX 5090 D integrates 170 ray tracing cores and 680 tensor cores. The LX ULTRA has no ray tracing cores and no tensor cores listed. This means hardware-accelerated ray tracing and tensor-based operations are exclusive to the RTX 5090 D.

The RTX 5090 D's FP16 performance matches its FP32 performance at a 1:1 ratio, indicating unified throughput across precision levels. The LX ULTRA's FP16 is exactly double its FP32 at a 2:1 ratio, a configuration that typically indicates separate or rate-limited FP16 paths.

The RTX 5090 D belongs to the GeForce 50 generation, with the GeForce 40 as its predecessor and GeForce 60 as its successor. The LX ULTRA belongs to the 7G100 generation with no predecessor or successor listed. The RTX 5090 D's release date is recorded as 2025-01-29, while the LX ULTRA's is 2026-03-16.

The RTX 5090 D supports Vulkan 1.4; the LX ULTRA supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

The RTX 5090 D's memory clock is listed as 1750 MHz with 28 Gbps effective throughput, while the LX ULTRA's memory clock is 2250 MHz with 18 Gbps effective throughput. The higher physical clock on the LX ULTRA does not translate into higher effective bandwidth due to the narrower bus and older memory type.

The Verdict

The data supports only one conclusion: the RTX 5090 D is the dominant product in every recorded metric. Its average benchmark score of 77,712 places it in the 92nd percentile, while the LX ULTRA sits at the 50th percentile with no benchmark results. The RTX 5090 D exceeds the LX ULTRA in shading units (21,760 versus 6,144), TMUs (680 versus 192), ROPs (176 versus 96), memory capacity (32 GB versus 24 GB), memory bandwidth (1.79 TB/s versus 432.0 GB/s), and FP32 throughput (104.8 TFLOPS versus 24.58 TFLOPS).

The LX ULTRA has no recorded wins in any category. Its only advantages are a lower TDP (225 W versus 575 W), a smaller physical footprint, and a lower suggested PSU (550 W versus 950 W). These are operational characteristics, not performance advantages. The LX ULTRA also lacks ray tracing cores and tensor cores entirely.

For buyers who require maximum compute throughput, the RTX 5090 D is the only choice with verified performance data. Its nearest rival in the database, the AMD Radeon RX 6850M XT, sits only 1.6% ahead, and the RTX 5090 D leads the RX 6650M XT by 1.1%. The LX ULTRA cannot be positioned against these figures because no scores exist for it.

The RTX 5090 D also carries a launch MSRP of 2,299 USD. The LX ULTRA has no launch MSRP recorded.

The RTX 5090 D is the clear pick for any workload that depends on measured GPU performance, whether that is Vulkan compute (376,915 points), OpenCL (310,674 points), or DirectX 12 (14,326 points in 3DMark Steel Nomad). The LX ULTRA, with no benchmark data, cannot be recommended from the database as a performance alternative. Its 50th percentile ranking, without any supporting test scores, leaves its actual capabilities unverified.
