Architecture Differences

The two GPUs represent fundamentally different design philosophies. The NVIDIA GeForce RTX 5090 D V2 uses the Blackwell 2.0 architecture on the GB202 chip, fabricated on TSMC's 5 nm process. It packs 92,200 million transistors into a 750 mm² die, giving a transistor density of 122.9M per mm². The Lisuan Tech LX 7G100 uses the TrueGPU architecture on the 7G106 chip, fabricated on TSMC's 6 nm process. Its transistor count and die size are not recorded in the database.

The RTX 5090 D V2 integrates 21,760 shading units, 680 texture mapping units, and 176 render output units. It also includes 170 ray tracing cores and 680 tensor cores. The LX 7G100 has 6,144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing or tensor core counts recorded.

Compute capabilities differ substantially. The RTX 5090 D V2 provides 104.8 TFLOPS FP32 and the same 104.8 TFLOPS FP16 (1:1 ratio). The LX 7G100 delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). This indicates the NVIDIA card has a 1:1 FP16 to FP32 ratio, while the Lisuan card halves its FP16 throughput relative to FP32.

Memory architecture also diverges sharply. The RTX 5090 D V2 uses 24 GB of GDDR7 on a 384-bit interface, achieving 1.34 TB/s bandwidth. The LX 7G100 uses 12 GB of GDDR6 on a 192-bit interface, reaching 432.0 GB/s. Memory clocks are recorded at 1750 MHz (28 Gbps effective) for the NVIDIA card and 2250 MHz (18 Gbps effective) for the Lisuan card.

Interface and connectivity differ as well. The RTX 5090 D V2 uses PCIe 5.0 x16, while the LX 7G100 uses PCIe 4.0 x16. Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b for the NVIDIA card, versus 4x DisplayPort 1.4a for the Lisuan card. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the RTX 5090 D V2 supports Vulkan 1.4 while the LX 7G100 supports Vulkan 1.3.

The Verdict

The recorded data shows two GPUs at opposite ends of the performance spectrum. The NVIDIA GeForce RTX 5090 D V2 holds a percentile rank of 59 among all GPUs in the database, while the Lisuan Tech LX 7G100 sits at percentile 50. The RTX 5090 D V2 has a recorded benchmark score of 16504; the LX 7G100 has none.

For users requiring maximum compute throughput, the RTX 5090 D V2 is the clear choice based on FP32 output (104.8 TFLOPS versus 24.58 TFLOPS), memory bandwidth (1.34 TB/s versus 432.0 GB/s), and memory capacity (24 GB versus 12 GB). Its 21,760 shading units dwarf the 6,144 in the LX 7G100. The NVIDIA card also supports newer display outputs (DisplayPort 2.1b versus 1.4a) and a faster bus interface (PCIe 5.0 versus 4.0).

The LX 7G100 has advantages in power efficiency metrics from the data. Its TDP of 225 W is substantially lower than the 575 W of the RTX 5090 D V2, and its suggested PSU of 550 W is lower than the 950 W required for the NVIDIA card. It also uses a single 8-pin connector rather than a 16-pin connector.

The RTX 5090 D V2 was released on 2025-08-14 and has a recorded launch MSRP of 2,299 USD. The LX 7G100 has a release date of 2026-06-17 and no launch MSRP recorded. The NVIDIA card lists the GeForce 40 series as predecessor and GeForce 60 series as successor. The Lisuan card has no predecessor or successor recorded.

Benchmark results indicate the RTX 5090 D V2 lands within 1% of several mid-range workstation and gaming GPUs in the nearest rivals list, including the NVIDIA T400, AMD Radeon PRO W7500, NVIDIA RTX PRO 6000 Blackwell, and AMD Radeon RX 5700 XT. This suggests its 16504 score represents a specific workload profile rather than a universal performance crown.

The LX 7G100 lacks any recorded benchmark data, making direct performance comparisons impossible beyond the raw specification differences. Users needing verified performance numbers would rely on the RTX 5090 D V2's recorded results.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The RTX 5090 D V2 has a single recorded benchmark score of 16504 in the 3DMark Steel Nomad DX12 test, while the LX 7G100 has an empty benchmark list.

In the absence of direct comparisons, the specification deltas provide the measurable differences. The RTX 5090 D V2 delivers 4.26 times the FP32 throughput of the LX 7G100 (104.8 TFLOPS versus 24.58 TFLOPS). Its FP16 output is 104.8 TFLOPS versus 49.15 TFLOPS, a 2.13 times advantage. The NVIDIA card's pixel rate of 423.6 GPixel/s exceeds the LX 7G100's 192.0 GPixel/s by a factor of 2.2. Texture rate shows the largest gap: 1,636.8 GTexel/s versus 384.0 GTexel/s, a 4.26 times difference.

Memory bandwidth favors the RTX 5090 D V2 at 1.34 TB/s versus 432.0 GB/s, a 3.1 times advantage. The NVIDIA card carries twice the memory capacity (24 GB versus 12 GB) and a wider bus (384 bit versus 192 bit). The LX 7G100 records a higher memory clock in MHz (2250 MHz versus 1750 MHz), but its GDDR6 memory and narrower bus produce lower effective bandwidth.

The nearest rivals data for the RTX 5090 D V2 provides context for its 16504 score. The NVIDIA T400 scores 16508, a 0% delta. The AMD Radeon PRO W7500 scores 16415, 0.5% lower. The NVIDIA RTX PRO 6000 Blackwell scores 16408, 0.6% lower. The AMD Radeon RX 5700 XT scores 16361, 0.9% lower. These four GPUs bracket the RTX 5090 D V2 within a narrow 0.9% band, indicating the recorded score positions it among mid-range performers in this specific test despite its flagship specifications.

The LX 7G100 has no nearest rivals and no percentile context beyond its 50th percentile rank. Its specifications suggest a lower-tier positioning, but the absence of benchmark data prevents quantitative comparison. The recorded data confirms the RTX 5090 D V2 as the higher-performing GPU across every measured compute and memory metric, while the LX 7G100 offers lower power consumption and a smaller physical footprint.
