AMD Radeon RX 7400 vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison: the AMD Radeon RX 7400 has a full set of benchmark scores, while the Lisuan Tech LX PRO has no benchmark entries in the database. This absence of measurement data for the LX PRO means no direct head-to-head scores exist. The RX 7400's average benchmark score is 2467, placing it in the 17th percentile of all GPUs. Its nearest rivals include the AMD Radeon 8040S (average score 2440, 1.1% behind), NVIDIA GeForce 710M (2433, 1.4% behind), Intel HD Graphics 610 (2425, 1.8% behind), and NVIDIA GeForce GT 710M (2422, 1.9% behind). These narrow deltas indicate the RX 7400 sits in a tightly clustered performance band.

The RX 7400's individual benchmark results show a wide spread across test types. In PassMark G3D it scores 11897, which is its strongest result by a substantial margin. The PassMark G2D result is 1209, while GPU compute reaches 5152. DirectX 9 testing produces a score of 176, DirectX 11 yields 97, and DirectX 10 drops to 59. The lowest result is DirectX 12 at 44. The 3DMark Steel Nomad DX12 test records 1103 points. These figures indicate the card's performance varies significantly depending on the graphics API and workload type.

The LX PRO, by contrast, has an average benchmark score of 0 and no recorded tests. The database lists its percentile as 50, but this figure cannot be validated against any actual measurements. Without benchmark entries, the data cannot confirm how the LX PRO would perform in the same tests. The RX 7400's 17th percentile ranking is derived from real scores, whereas the LX PRO's 50th percentile appears to be an unverified placeholder or estimate. The absence of head-to-head benchmark entries for both cards means no comparative score analysis is possible from the recorded data.

The RX 7400's nearest rival deltas, all under 2%, show how closely packed its performance tier is. A 1.1% lead over the AMD Radeon 8040S and a 1.9% lead over the NVIDIA GeForce GT 710M represent minor margins in real-world terms. These small percentage differences suggest the RX 7400 is competitive with its immediate peers but does not dominate them. The data implies that a user moving between these cards would notice little difference in most workloads. For the LX PRO, the lack of scores means no such comparison can be drawn.

The Verdict

The data presents a clear asymmetry. The AMD Radeon RX 7400 has verifiable benchmark results, including an average score of 2467 and a 17th percentile ranking. The Lisuan Tech LX PRO has zero benchmark scores and an unverified 50th percentile figure. From a purely data-driven perspective, the RX 7400 is the only card with measured performance evidence. Users seeking a card with documented results would select the RX 7400 based on the availability of its benchmark data.

The LX PRO's 50th percentile placement, if taken at face value, would suggest it outperforms the RX 7400, which sits at the 17th percentile. However, this percentile is not supported by any recorded benchmark scores. The RX 7400's average score of 2467 comes from eight distinct tests, providing a verified baseline. The LX PRO's average score of 0 indicates no measurements exist to confirm its claimed percentile. The verdict from the data alone is straightforward: the RX 7400 has proven performance, while the LX PRO's performance remains unquantified.

The RX 7400's nearest rivals, all scoring between 2422 and 2440, reinforce its position in a modest performance tier. Its 17th percentile ranking means it outperforms only a small fraction of all GPUs in the database. The LX PRO's theoretical 50th percentile would place it above the RX 7400, but without scores, this is speculative. Users who prioritize verified data should treat the RX 7400 as the measured option and the LX PRO as an unknown quantity.

Architecture Differences

The two cards use the same 6 nm process node from TSMC, but their underlying designs diverge sharply. The AMD Radeon RX 7400 uses the Navi 33 chip with RDNA 3.0 architecture and the codename "Hotpink Bonefish." It belongs to the Navi III generation (RX 7000 series). The Lisuan Tech LX PRO uses a chip designated 7G105 with an architecture called TrueGPU, belonging to the 7G100 generation. The RX 7400 contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per mm². The LX PRO's transistor count and die size are listed as unknown in the database.

The RX 7400's compute configuration includes 1792 shading units, 112 texture mapping units, and 64 raster output units. It also features 28 ray tracing cores. The LX PRO has substantially higher counts: 6144 shading units, 192 TMUs, and 96 ROPs, but no ray tracing cores are listed. The LX PRO's FP32 performance is 24.58 TFLOPS versus the RX 7400's 16.49 TFLOPS, a difference of roughly 8 TFLOPS. FP16 performance follows the same pattern: the LX PRO delivers 49.15 TFLOPS compared to the RX 7400's 32.97 TFLOPS. Pixel rate for the LX PRO is 192.0 GPixel/s versus 147.2 GPixel/s for the RX 7400, and texture rate is 384.0 GTexel/s versus 257.6 GTexel/s.

Memory configurations differ notably. The RX 7400 uses 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. Both cards list a memory clock of 2250 MHz with 18 Gbps effective speed. The LX PRO's larger memory capacity and wider bus give it a bandwidth advantage of 144 GB/s. API support also differs: both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the RX 7400 supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3. Display outputs vary as well, with the RX 7400 offering 1x HDMI 2.1a and 3x DisplayPort 2.1, while the LX PRO offers 4x DisplayPort 1.4a.

Where Each One Wins

The AMD Radeon RX 7400 wins in the domain of verified performance data. Its eight benchmark scores provide concrete evidence of its capabilities, and its average score of 2467 places it within 1.9% of its nearest rivals. The card's DirectX 9 score of 176 and DirectX 11 score of 97 suggest it handles older API workloads relatively well compared to its DirectX 12 score of 44. The RX 7400 also wins on efficiency metrics: its 43 W TDP and 200 W suggested PSU are dramatically lower than the LX PRO's 225 W TDP and 550 W suggested PSU. For systems with limited power delivery, the RX 7400 is the clear choice based on the recorded data.

The RX 7400 also wins on physical footprint considerations. Its dimensions are not listed in the database, but its dual-slot width and single 6-pin connector suggest a compact design. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width, which requires more case space. The RX 7400's PCIe 4.0 x8 interface is narrower than the LX PRO's PCIe 4.0 x16, which may matter in bandwidth-sensitive scenarios, but the RX 7400's lower power draw makes it more accessible for smaller builds.

The Lisuan Tech LX PRO wins on raw specifications. Its 24 GB of GDDR6 memory triples the RX 7400's 8 GB capacity. Its 6144 shading units are more than three times the RX 7400's 1792. FP32 throughput of 24.58 TFLOPS exceeds the RX 7400's 16.49 TFLOPS by roughly 49%. Memory bandwidth of 432.0 GB/s outperforms the RX 7400's 288.0 GB/s. Pixel rate and texture rate are also higher. The LX PRO's 192-bit bus and 96 ROPs indicate a design aimed at higher-resolution rendering and heavier texture workloads.

The LX PRO also wins on display output count, offering 4x DisplayPort 1.4a versus the RX 7400's 1x HDMI 2.1a and 3x DisplayPort 2.1. While the RX 7400 supports newer DisplayPort versions, the LX PRO provides more total outputs. The LX PRO's production status is listed as Active, while the RX 7400's production status is not recorded. Its release date of March 2026 is later than the RX 7400's August 2025 release. The LX PRO's 50th percentile ranking, though unverified, is higher than the RX 7400's 17th percentile, suggesting its intended performance class is above the RX 7400.
