AMD Radeon RX 7400 OEM vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Radeon RX 7400 OEM or the Lisuan Tech LX PRO. Both entries show an average benchmark score of zero and no head-to-head results, so a direct performance comparison cannot be established from measured data. The absence of benchmark records means neither product can be positioned above the other in raw performance based on the current database contents.

However, the specification sheets allow for a theoretical comparison of compute capabilities. The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 compute, while the AMD Radeon RX 7400 OEM delivers 7.885 TFLOPS. This puts the LX PRO at roughly three times the FP32 throughput of the AMD part based on the recorded figures. In FP16 workloads, the LX PRO reaches 49.15 TFLOPS with a 2:1 ratio, whereas the RX 7400 OEM achieves 7.885 TFLOPS at a 1:1 ratio, meaning the LX PRO has a sixfold advantage in half-precision compute if the application can use the 2:1 path.

Pixel throughput follows a similar pattern. The LX PRO renders at 192.0 GPixel/s, compared to 70.40 GPixel/s for the RX 7400 OEM. Texture rate also favors the LX PRO at 384.0 GTexel/s versus 123.2 GTexel/s. These figures indicate a substantial raw throughput gap, but without actual benchmark scores, the practical impact on game frame rates or application performance remains unquantified in the database.

Both cards sit at the 50th percentile among all GPUs in the database, and neither has any nearest rivals listed. Both also support DirectX 12 Ultimate (12_2) and OpenGL 4.6, so API-level feature support is identical on those fronts. The AMD card supports Vulkan 1.4, while the Lisuan card supports Vulkan 1.3, a minor version difference that may affect compatibility with certain Vulkan extensions.

Where Each One Wins

The Lisuan Tech LX PRO wins in every recorded compute and memory metric. Its FP32 output of 24.58 TFLOPS, FP16 output of 49.15 TFLOPS, pixel rate of 192.0 GPixel/s, and texture rate of 384.0 GTexel/s all exceed the corresponding figures for the AMD Radeon RX 7400 OEM. The 24 GB memory capacity, 192-bit bus, and 432.0 GB/s bandwidth give it a clear advantage in memory-heavy workloads such as large dataset processing, high-resolution texture streaming, or multi-application GPU compute tasks. The 2:1 FP16 ratio suggests the LX PRO can handle mixed-precision workloads more efficiently than the AMD card's 1:1 ratio.

The AMD Radeon RX 7400 OEM wins in efficiency-focused scenarios. Its 55 W TDP is 170 W lower than the LX PRO's 225 W, and its 250 W suggested PSU requirement is 300 W lower than the LX PRO's 550 W. The single-slot form factor and 167 mm length make it suitable for compact chassis installations where the dual-slot, 248 mm LX PRO would not fit. The RX 7400 OEM also supports Vulkan 1.4, one version newer than the LX PRO's Vulkan 1.3, and includes DisplayPort 2.1 outputs, while the LX PRO uses DisplayPort 1.4a. The AMD card's 28 ray tracing cores provide a hardware feature that the LX PRO does not list.

Architecture Differences

The AMD Radeon RX 7400 OEM uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is fabricated on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die, giving a transistor density of 65.2M per mm². Its predecessor is listed as Navi II and its successor as Navi IV.

The Lisuan Tech LX PRO uses the 7G105 chip with an architecture labeled TrueGPU, belonging to the 7G100 generation. It is also fabricated on a 6 nm process at TSMC, but its transistor count, die size, and transistor density are unknown in the database. No predecessor or successor is recorded for this product.

The core configurations differ substantially. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs, while the RX 7400 OEM has 1792 shading units, 112 TMUs, and 64 ROPs. The AMD card includes 28 ray tracing cores, a feature absent from the LX PRO's recorded specifications. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the AMD card supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3.

Memory architecture diverges in capacity, bus width, and speed. The LX PRO uses 24 GB of GDDR6 on a 192-bit bus with a memory clock of 2250 MHz (18 Gbps effective), yielding 432.0 GB/s. The RX 7400 OEM uses 8 GB of GDDR6 on a 128-bit bus with a memory clock of 1350 MHz (10.8 Gbps effective), yielding 172.8 GB/s.

The Verdict

The database records no benchmark scores for either GPU, so the verdict must rely entirely on the specification sheet. The Lisuan Tech LX PRO is the higher-throughput card by every recorded compute and memory measure. Its FP32 figure of 24.58 TFLOPS, FP16 figure of 49.15 TFLOPS, 432.0 GB/s bandwidth, and 24 GB capacity position it for compute-heavy workloads that can utilize its 6144 shading units and 192 TMUs. The 2:1 FP16 ratio indicates support for reduced-precision acceleration that the AMD card's 1:1 ratio does not offer. The LX PRO also uses a PCIe 4.0 x16 interface, double the lane count of the RX 7400 OEM's PCIe 4.0 x8.

The AMD Radeon RX 7400 OEM is the lower-power, smaller-footprint option. Its 55 W TDP, 250 W suggested PSU, single-slot design, and 167 mm length make it the appropriate choice for constrained systems where the LX PRO's 225 W TDP, 550 W PSU requirement, and dual-slot 248 mm length would be impractical. The RX 7400 OEM adds 28 ray tracing cores, Vulkan 1.4 support, and DisplayPort 2.1 outputs, features that the LX PRO does not list.

For a user selecting between these two on the recorded data alone, the decision hinges on workload type and system constraints. The Lisuan Tech LX PRO suits applications requiring large memory pools, high FP16 throughput, or substantial raw compute. The AMD Radeon RX 7400 OEM suits low-power builds, small form factor systems, or ray tracing workloads where its 28 RT cores can be used. Both cards hold the same 50th percentile position in the database, and with no benchmark scores or rival comparisons available, the specification differences above constitute the entire basis for differentiation.
