AMD Radeon RX 9050 vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The recorded data splits these two cards into clearly different roles. The AMD Radeon RX 9050 is built around efficiency and modern feature support, while the Lisuan Tech LX PRO is built around raw throughput and memory capacity. The benchmark wins are not listed in the database, so the use-case split must be derived from the architectural and specification differences.

The RX 9050 wins in scenarios that favor its compact, low-power design. It uses a 4 nm process, draws 92 W TDP, and requires only a 250 W suggested PSU. This makes it suitable for systems where power delivery and thermal output are limited. It also carries PCIe 5.0 x16 support, which matters for bandwidth-sensitive workloads on newer platforms. The RX 9050 supports DisplayPort 2.1a, which is a newer standard than the DisplayPort 1.4a found on the LX PRO. For display connectivity, the RX 9050 offers one HDMI 2.1b port and two DisplayPort 2.1a outputs.

The LX PRO wins in scenarios that demand large memory and high compute throughput. It has 24 GB of GDDR6 memory on a 192 bit bus, delivering 432.0 GB/s of bandwidth. The RX 9050 has 8 GB on a 128 bit bus, delivering 288.0 GB/s. The LX PRO also has 6144 shading units, 192 texture mapping units, and 96 ROPs, compared to 1024 shading units, 64 TMUs, and 64 ROPs on the RX 9050. The FP32 throughput of the LX PRO is 24.58 TFLOPS, more than double the 10.65 TFLOPS of the RX 9050. The LX PRO also has four DisplayPort 1.4a outputs, allowing more simultaneous displays.

Architecture Differences

The two cards come from different design philosophies. The AMD Radeon RX 9050 uses the Navi 44 chip, part of the RDNA 4.0 architecture, built on a 4 nm process at TSMC. It has 29,700 million transistors on a 199 mm² die, giving a transistor density of 149.2M per mm². The LX PRO uses the 7G105 chip with the TrueGPU architecture, built on a 6 nm process also at TSMC. Its transistor count and die size are not recorded in the database.

The RX 9050 has 16 RT cores, while the LX PRO has no recorded RT core count. This indicates hardware ray tracing support on the AMD side, with no comparable feature listed for the Lisuan product. The RX 9050 also supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.

The FP16 performance differs in ratio. The RX 9050 delivers FP16 at 10.65 TFLOPS with a 1:1 ratio to FP32. The LX PRO delivers FP16 at 49.15 TFLOPS with a 2:1 ratio. This means the LX PRO has a dedicated or accelerated FP16 path, while the RX 9050 treats FP16 and FP32 with equal throughput.

The memory clock is identical at 2250 MHz, 18 Gbps effective. Both use GDDR6. The LX PRO has a wider 192 bit bus and more memory, 24 GB versus 8 GB. The RX 9050 uses PCIe 5.0 x16, while the LX PRO uses PCIe 4.0 x16. The RX 9050 has a dual-slot cooler and a single 8-pin power connector. The LX PRO also has a dual-slot cooler but uses a single 16-pin power connector and requires a 550 W suggested PSU.

The LX PRO has recorded physical dimensions: 248 mm length, 118 mm height, and 48 mm width. The RX 9050 has no recorded dimensions in the database.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark scores for these two cards. The analysis must therefore rely on the computed specifications to establish performance deltas.

The largest gap is in FP32 compute. The LX PRO delivers 24.58 TFLOPS against 10.65 TFLOPS for the RX 9050. That is a 130.8% advantage for the LX PRO. In FP16, the LX PRO delivers 49.15 TFLOPS against 10.65 TFLOPS, a 361.5% advantage. The 2:1 FP16 ratio on the LX PRO explains the larger gap in that workload.

Texture rate shows a similar pattern. The LX PRO reaches 384.0 GTexel/s, while the RX 9050 reaches 166.4 GTexel/s. That is a 130.8% advantage, matching the FP32 ratio because both derive from the same shading unit and TMU count. Pixel rate is closer: the LX PRO reaches 192.0 GPixel/s against 166.4 GPixel/s for the RX 9050, a 15.4% advantage.

Memory bandwidth favors the LX PRO at 432.0 GB/s versus 288.0 GB/s, a 50.0% advantage. The 24 GB capacity is triple the 8 GB on the RX 9050. The RX 9050 counters with a newer PCIe interface, PCIe 5.0 x16 versus PCIe 4.0 x16, and a newer display standard, DisplayPort 2.1a versus DisplayPort 1.4a.

Power efficiency reverses the compute comparison. The RX 9050 draws 92 W TDP, while the LX PRO draws 225 W TDP. Per watt, the RX 9050 delivers 0.116 TFLOPS/W in FP32, while the LX PRO delivers 0.109 TFLOPS/W. The difference is small, but the RX 9050 achieves near-parity in FP32 efficiency while using far less total power. The suggested PSU requirement also reflects this: 250 W for the RX 9050 against 550 W for the LX PRO.

The Verdict

The data points to two distinct buyers. The AMD Radeon RX 9050 is the choice for systems with limited power budgets, newer platform features, and a need for hardware ray tracing. Its 92 W TDP, 250 W suggested PSU, PCIe 5.0 x16 interface, and 16 RT cores make it appropriate for compact builds or upgrades where the LX PRO would require a larger power supply and more chassis clearance.

The Lisuan Tech LX PRO is the choice for workloads that need large memory capacity and high raw compute. Its 24 GB frame buffer, 432.0 GB/s bandwidth, and 24.58 TFLOPS FP32 throughput put it well ahead in memory-heavy and compute-heavy tasks. The 4x DisplayPort 1.4a outputs also allow more displays than the 3 outputs on the RX 9050.

There is no recorded launch MSRP for either card, so no price-based comparison is possible from the database. The production status for both is Active. The RX 9050 has a release date of 2026-07-27, while the LX PRO has a release date of 2026-03-16. The RX 9050 lists Navi III as its predecessor, while the LX PRO has no recorded predecessor.

The RX 9050 wins on efficiency, modern connectivity, and ray tracing hardware. The LX PRO wins on compute throughput, memory size, and bandwidth. Neither card is a general-purpose winner in the recorded data. The correct pick depends entirely on whether the workload favors power efficiency or raw capacity.
