AMD Radeon RX 7400 vs Lisuan Tech LX ULTRA Comparison

AMD Radeon RX 7400 and Lisuan Tech LX ULTRA represent two very different interpretations of a discrete graphics card. The RX 7400 is a low-power, compact solution built on AMD’s RDNA 3.0 architecture, while the LX ULTRA is a larger, more power-hungry card with a unique TrueGPU architecture from Lisuan Tech. The database contains complete benchmark data for the RX 7400, but the LX ULTRA has no recorded benchmark scores, meaning comparisons rely on architectural specifications and the RX 7400’s measured performance.

Where Each One Wins

The AMD Radeon RX 7400 wins decisively in measured benchmark performance. Its recorded results include a 3DMark Steel Nomad DX12 score of 1103, a PassMark G3D score of 11897, and a PassMark G2D score of 1209. The LX ULTRA has no benchmark entries in the database, so it cannot claim any recorded performance victories. The RX 7400 also wins on efficiency metrics, with a TDP of 43 W versus the LX ULTRA’s 225 W, and a suggested PSU of 200 W versus 550 W. This places the RX 7400 in a class of cards that can operate with minimal system power requirements.

The LX ULTRA wins strictly on raw specification counts. It has 6144 shading units, 192 texture mapping units, and 96 render output units, compared to the RX 7400’s 1792 shading units, 112 TMUs, and 64 ROPs. Its memory subsystem is larger: 24 GB of GDDR6 on a 192-bit bus delivers 432.0 GB/s of bandwidth, whereas the RX 7400 has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s. The LX ULTRA also posts higher theoretical rates: 24.58 TFLOPS FP32 versus 16.49 TFLOPS, 49.15 TFLOPS FP16 versus 32.97 TFLOPS, 384.0 GTexel/s versus 257.6 GTexel/s, and 192.0 GPixel/s versus 147.2 GPixel/s. These numbers indicate that the LX ULTRA is built for workloads that scale with raw compute and memory capacity, but without benchmark data, its real-world advantage remains unverified.

Architecture Differences

The two cards use different underlying designs. The AMD Radeon RX 7400 uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi III generation. It is manufactured on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2 million per square millimeter. The LX ULTRA uses the 7G105 chip with TrueGPU architecture from the 7G100 generation. It is also built on a 6 nm process at TSMC, but its transistor count, die size, and transistor density are listed as unknown in the database.

Memory architecture differs significantly. The RX 7400 has 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth, while the LX ULTRA has 24 GB of GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. Both cards run memory at 2250 MHz with 18 Gbps effective speed. The LX ULTRA’s larger memory pool and wider bus give it a clear capacity and bandwidth advantage, which matters for high-resolution textures or large compute datasets.

Compute resources also differ. The RX 7400 includes 28 ray tracing cores, while the LX ULTRA lists no ray tracing cores in the database. The RX 7400 has a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz; the LX ULTRA has no recorded base, boost, or game clocks. The RX 7400 uses a PCIe 4.0 x8 interface, while the LX ULTRA uses PCIe 4.0 x16, giving the latter double the available bus lanes for data transfer.

Power delivery and physical design also separate the cards. The RX 7400 is a dual-slot card with a single 6-pin power connector and a 43 W TDP. The LX ULTRA is also dual-slot but uses a single 16-pin power connector, has a 225 W TDP, and measures 268 mm in length, 112 mm in height, and 40 mm in width. The RX 7400 has no recorded dimensions in the database. Display outputs differ: the RX 7400 offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the LX ULTRA offers 4x DisplayPort 1.4a.

API support is similar with some differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 7400 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RX 7400 was released on August 7, 2025, and the LX ULTRA on March 16, 2026. The LX ULTRA has an active production status; the RX 7400’s production status is not recorded.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two cards, and the LX ULTRA has no individual benchmark scores. Therefore, direct numerical comparison is impossible. The RX 7400’s recorded benchmarks can be examined on their own. Its 3DMark Steel Nomad DX12 score of 1103 places it in the 17th percentile among all GPUs. Its PassMark G3D score of 11897 and PassMark G2D score of 1209 show a strong gap between 3D and 2D performance. Additional PassMark scores include DirectX 10 at 59, DirectX 11 at 97, DirectX 12 at 44, DirectX 9 at 176, and GPU compute at 5152. The average benchmark score for the RX 7400 is 2467.

The nearest rivals to the RX 7400 in the database are the AMD Radeon 8040S with an average score of 2440 and a delta of 1.1 percent, the NVIDIA GeForce 710M with 2433 and 1.4 percent, the Intel HD Graphics 610 with 2425 and 1.8 percent, and the NVIDIA GeForce GT 710M with 2422 and 1.9 percent. These deltas show that the RX 7400’s average score is only slightly higher than these integrated and entry-level mobile parts, suggesting that its benchmark average is not representative of its peak 3D performance. The 3DMark Steel Nomad score of 1103 and PassMark G3D score of 11897 indicate that the RX 7400’s performance varies widely by test, with G3D being its strongest area.

The LX ULTRA’s average benchmark score is listed as 0, and its percentile versus all GPUs is 50, which appears to be a placeholder given the absence of any benchmark runs. Without measured scores, its performance relative to the RX 7400 cannot be quantified. The theoretical FP32 throughput of 24.58 TFLOPS for the LX ULTRA is 49 percent higher than the RX 7400’s 16.49 TFLOPS, but theoretical rates do not translate directly to real-world results, especially when one card has no recorded benchmarks and the other is a low-power design with modest thermal headroom.

The Verdict

The data supports a clear split between these two cards. The AMD Radeon RX 7400 is a measured performer with a full set of benchmark results. It delivers a 3DMark Steel Nomad DX12 score of 1103 and a PassMark G3D score of 11897, placing it in the 17th percentile of all GPUs. Its 43 W TDP and 200 W suggested PSU make it suitable for systems with limited power budgets. The RX 7400’s nearest rivals, all with average scores between 2422 and 2440, show that its overall average of 2467 is competitive within its immediate performance class, though its peak 3D results are substantially higher than its average suggests.

The Lisuan Tech LX ULTRA is a specification-heavy card with no recorded benchmark results. It offers 24 GB of GDDR6, 6144 shading units, 24.58 TFLOPS FP32, and a 192-bit memory bus, all of which exceed the RX 7400’s corresponding specifications. Its 225 W TDP and 550 W suggested PSU indicate a much higher power draw. The LX ULTRA’s larger memory capacity and bandwidth could benefit workloads that demand large data sets, but the absence of any benchmark scores means the database cannot confirm real-world performance.

Users who prioritize verified performance and low power consumption should consider the RX 7400. Its measured scores and modest power requirements make it a functional option for standard graphics workloads. Users who require maximum memory capacity and theoretical compute throughput may look at the LX ULTRA, but they will do so without any benchmark validation. The RX 7400 is the only card in this comparison with recorded performance data, and that alone gives it an evidentiary advantage.
