AMD Radeon RX 9050 vs Lisuan Tech LX MAX Comparison

Where Each One Wins

The recorded data for these two GPUs shows no direct head-to-head benchmark runs, so the use-case split must be derived from their architectural specifications and raw compute capabilities. The AMD Radeon RX 9050 is positioned as a low-power, efficiency-oriented part with a 92 W TDP, while the Lisuan Tech LX MAX is a high-throughput design with a 225 W TDP and significantly larger compute resources.

For rasterization-heavy workloads that favor raw shader throughput, the Lisuan Tech LX MAX holds the advantage. Its 6144 shading units versus 1024 on the RX 9050, combined with 192 texture mapping units and 96 render output units, gives it a large lead in pixel and texture fill rates. The database shows the LX MAX delivers 192.0 GPixel/s and 384.0 GTexel/s, whereas the RX 9050 produces 166.4 GPixel/s and 166.4 GTexel/s. The LX MAX's texture rate is more than double, which matters for games that are fill-rate bound.

The memory subsystem also favors the LX MAX for capacity-sensitive workloads. It carries 12 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s of bandwidth. The RX 9050 has 8 GB on a 128-bit bus, giving 288.0 GB/s. Applications that exceed 8 GB of video memory, such as high-resolution texture packs or large dataset rendering, will require the LX MAX. The bandwidth delta is substantial, 432.0 GB/s versus 288.0 GB/s, a 50% advantage for the LX MAX.

Conversely, the AMD Radeon RX 9050 wins in scenarios where power draw and system integration matter. Its 92 W TDP is less than half of the LX MAX's 225 W. The suggested power supply for the RX 9050 is 250 W, while the LX MAX demands 550 W. The RX 9050 uses a single 8-pin connector; the LX MAX uses a 16-pin connector. For compact builds or systems with modest power delivery, the RX 9050 is the only viable choice among these two.

The RX 9050 also leads in interface generation. It uses PCIe 5.0 x16, while the LX MAX uses PCIe 4.0 x16. For workloads that are sensitive to bus transfer rates, the newer interface provides more headroom, though the practical impact depends on the workload. Additionally, the RX 9050 supports DisplayPort 2.1a outputs, whereas the LX MAX only has DisplayPort 1.4a. The RX 9050 also includes HDMI 2.1b, which the LX MAX lacks entirely.

Architecture Differences

The two GPUs come from different architectural lineages. AMD's RX 9050 uses the Navi 44 chip built on RDNA 4.0 architecture, fabricated on a 4 nm process at TSMC. The LX MAX uses a chip labeled 7G106 with the "TrueGPU" architecture, manufactured on a 6 nm process, also at TSMC. The process node difference is significant: 4 nm versus 6 nm affects transistor density and power efficiency. The RX 9050 packs 29,700 million transistors into a 199 mm² die, giving a transistor density of 149.2M per mm². The LX MAX's transistor count and die size are listed as unknown in the database.

The compute layout differs sharply. The RX 9050 has 1024 shading units, 64 TMUs, and 64 ROPs. The LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs. The RX 9050 includes 16 dedicated ray tracing cores; the LX MAX lists no RT core count. For FP32 compute, the LX MAX delivers 24.58 TFLOPS against the RX 9050's 10.65 TFLOPS. The FP16 situation is more nuanced: the RX 9050 runs FP16 at 10.65 TFLOPS (1:1 ratio with FP32), while the LX MAX achieves 49.15 TFLOPS (2:1 ratio). The LX MAX's FP16 throughput is over 4.6 times its FP32 rate, indicating a design optimized for mixed-precision or AI-style workloads, whereas the RX 9050 offers no such acceleration.

Memory architecture also diverges. Both use GDDR6, but the RX 9050 has 8 GB on a 128-bit bus, and the LX MAX has 12 GB on a 192-bit bus. The memory clock is identical at 2250 MHz (18 Gbps effective), so the bandwidth difference comes entirely from bus width. The LX MAX's 432.0 GB/s versus 288.0 GB/s reflects the wider bus.

API support shows minor differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 9050 supports Vulkan 1.4; the LX MAX supports Vulkan 1.3. The RX 9050's newer Vulkan version may offer additional features for compatible applications.

Physical dimensions are only recorded for the LX MAX: 248 mm length, 118 mm height, 48 mm width. The RX 9050's dimensions are not listed. Both are dual-slot cards. The power connectors differ: 1x 8-pin for the RX 9050, 1x 16-pin for the LX MAX. The LX MAX's 225 W TDP and 550 W suggested PSU reflect a much higher power envelope.

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either GPU. The headToHeadBenchmarks array is empty, and both have zero wins in the winsA and winsB fields. The average benchmark score is 0 for both, and the percentile versus all GPUs is 50 for both. As a result, the comparison must rely on the recorded specification data rather than measured performance results.

The largest computational gap is in FP32 throughput. The LX MAX delivers 24.58 TFLOPS, which is 2.31 times the RX 9050's 10.65 TFLOPS. In texture fill rate, the LX MAX's 384.0 GTexel/s is 2.31 times the RX 9050's 166.4 GTexel/s. The pixel rate gap is smaller: 192.0 GPixel/s versus 166.4 GPixel/s, a 1.15 times advantage for the LX MAX. The FP16 gap is the widest of all: 49.15 TFLOPS versus 10.65 TFLOPS, a 4.62 times advantage.

Memory bandwidth favors the LX MAX by a factor of 1.5, with 432.0 GB/s against 288.0 GB/s. Memory capacity favors the LX MAX by 1.5 times as well, 12 GB versus 8 GB.

The RX 9050 counters with power efficiency. Its TDP is 92 W versus 225 W, meaning the LX MAX requires 2.45 times the power. The suggested PSU is 250 W for the RX 9050 and 550 W for the LX MAX, a 2.2 times difference. The RX 9050 also uses a smaller process node (4 nm versus 6 nm) and newer bus interface (PCIe 5.0 versus PCIe 4.0).

In shading units, the LX MAX has exactly 6 times as many as the RX 9050 (6144 versus 1024). The TMU count is exactly 3 times (192 versus 64), and the ROP count is 1.5 times (96 versus 64). The RX 9050 has 16 RT cores; the LX MAX has none listed.

The FP32 per shading unit can be derived: the RX 9050 achieves 10.65 TFLOPS across 1024 units, which is 10.40 GFLOPS per unit. The LX MAX achieves 24.58 TFLOPS across 6144 units, which is 4.00 GFLOPS per unit. This indicates the RX 9050's RDNA 4.0 architecture is more efficient per shader, likely due to the 4 nm process, while the LX MAX relies on raw unit count.

The Verdict

The data points to a clear split. The Lisuan Tech LX MAX is the higher-performance part in raw compute, memory capacity, and memory bandwidth. Its 24.58 TFLOPS FP32, 432.0 GB/s bandwidth, and 12 GB memory make it suitable for demanding rendering workloads, high-resolution textures, and compute-heavy tasks. Its FP16 throughput of 49.15 TFLOPS indicates a strong capability for workloads that leverage half-precision arithmetic. The 6144 shading units and 192 TMUs give it a decisive edge in shader-bound and texture-bound scenarios.

The AMD Radeon RX 9050 is the efficiency-oriented alternative. Its 92 W TDP and 250 W suggested PSU allow installation in systems where the LX MAX's 225 W TDP and 550 W PSU requirement would be impractical. The 4 nm process node, PCIe 5.0 interface, and DisplayPort 2.1a outputs make it the more modern platform in several respects. The RX 9050 also has 16 ray tracing cores, which the LX MAX lacks entirely.

For users who prioritize raw performance and have the power delivery to support it, the LX MAX is the stronger choice based on every compute metric in the database. For users who prioritize power efficiency, modern connectivity, or ray tracing support, the RX 9050 is the appropriate selection. The absence of direct benchmark scores means the performance advantage of the LX MAX is theoretical, derived from specification comparisons, not measured results.
