AMD Radeon RX 9050 vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark results for the AMD Radeon RX 9050 and the Lisuan Tech LX ULTRA. Neither card has a benchmark score entered in the system, and the wins counters for both items are set to zero. The percentile versus all GPUs is identical for both, at 50. This means the comparison must rest entirely on the architectural and specification data recorded for each card, not on measured performance deltas.

What the data does show is a clear split in design philosophy. The AMD Radeon RX 9050 uses the Navi 44 chip on the RDNA 4.0 architecture, built on a 4 nm process at TSMC. It packs 29,700 million transistors into a 199 mm² die, yielding a transistor density of 149.2M per mm². The Lisuan Tech LX ULTRA uses the 7G105 chip on the TrueGPU architecture, built on a 6 nm process, also at TSMC. Its transistor count and die size are not recorded in the database, so no density figure can be derived for it.

The compute resources differ dramatically. The RX 9050 carries 1,024 shading units, 64 texture mapping units, and 64 render output units. The LX ULTRA carries 6,144 shading units, 192 TMUs, and 96 ROPs. That is 6 times the shading units, 3 times the TMUs, and 1.5 times the ROPs. In raw shading capacity, the LX ULTRA is in a different class entirely, though the architectural differences between RDNA 4.0 and TrueGPU mean these counts are not directly comparable in efficiency terms.

Clock speeds tell a different story. The RX 9050 has a recorded base clock of 1330 MHz, a boost clock of 2600 MHz, and a game clock of 1920 MHz. The LX ULTRA has no base, boost, or game clock entries at all. The only clock data shared between the two is the memory clock, which is identical: 2250 MHz with 18 Gbps effective data rate.

The memory subsystem favors the LX ULTRA substantially. The RX 9050 has 8 GB of GDDR6 on a 128-bit bus, producing 288.0 GB/s of bandwidth. The LX ULTRA has 24 GB of GDDR6 on a 192-bit bus, producing 432.0 GB/s of bandwidth. That is 3 times the capacity and 1.5 times the bandwidth. For workloads that scale with memory size, such as large texture sets or high-resolution rendering, the LX ULTRA has a clear margin.

Fill rates and compute throughput follow the same pattern. The RX 9050 delivers 166.4 GPixel/s pixel rate and 166.4 GTexel/s texture rate, with FP32 performance of 10.65 TFLOPS and FP16 performance of 10.65 TFLOPS at a 1:1 ratio. The LX ULTRA delivers 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate, with FP32 performance of 24.58 TFLOPS and FP16 performance of 49.15 TFLOPS at a 2:1 ratio. The LX ULTRA is ahead by 15.4% in pixel throughput, 130.8% in texture throughput, 130.8% in FP32, and 361.5% in FP16.

Power draw is where the RX 9050 answers back. Its TDP is 92 W, with a suggested power supply of 250 W and a single 8-pin connector. The LX ULTRA has a TDP of 225 W, a suggested power supply of 550 W, and a single 16-pin connector. The RX 9050 draws less than half the power of the LX ULTRA. The efficiency ratio is stark: the RX 9050 delivers 10.65 TFLOPS at 92 W, while the LX ULTRA delivers 24.58 TFLOPS at 225 W. Per watt, the RX 9050 produces 0.116 TFLOPS per watt, while the LX ULTRA produces 0.109 TFLOPS per watt. The AMD card is marginally ahead in FP32 efficiency, but the gap is small.

The Verdict

The database shows two cards with no direct benchmark scores, so the verdict must be drawn from the recorded specifications. The Lisuan Tech LX ULTRA wins on raw compute capacity, memory capacity, memory bandwidth, texture throughput, and FP32 and FP16 performance. The AMD Radeon RX 9050 wins on process node, transistor density, power consumption, and FP32 efficiency per watt.

For a user who needs maximum compute throughput and large memory pools, the LX ULTRA is the only choice. Its 24 GB frame buffer and 432.0 GB/s bandwidth are figures the RX 9050 cannot approach. Its FP32 performance of 24.58 TFLOPS is more than double the RX 9050's 10.65 TFLOPS. Its FP16 performance of 49.15 TFLOPS is more than quadruple the RX 9050's 10.65 TFLOPS.

For a user who needs a low-power card with a small power supply requirement, the RX 9050 is the only choice. Its 92 W TDP and 250 W suggested PSU are less than half of the LX ULTRA's 225 W TDP and 550 W suggested PSU. The RX 9050 also uses a standard 8-pin connector, while the LX ULTRA requires a 16-pin connector. The RX 9050 is built on a 4 nm process versus the LX ULTRA's 6 nm process, and it packs more transistors per square millimeter: 149.2M versus an unknown figure for the LX ULTRA.

Neither card has a recorded launch MSRP, so no cost comparison is possible from the data.

Where Each One Wins

The AMD Radeon RX 9050 wins in power efficiency and physical footprint considerations. Its 92 W TDP allows for a modest 250 W power supply. It uses a single 8-pin power connector, which is more universally compatible with existing power supplies. Its 4 nm process node and 199 mm² die with 29,700 million transistors indicate a denser, more modern manufacturing approach. The RX 9050 supports PCIe 5.0 x16, while the LX ULTRA uses PCIe 4.0 x16. The RX 9050 also offers display outputs of 1x HDMI 2.1b and 2x DisplayPort 2.1a, which are newer display interface versions than the LX ULTRA's 4x DisplayPort 1.4a.

The Lisuan Tech LX ULTRA wins in every raw performance metric recorded. Its 24 GB memory capacity is 3 times the RX 9050's 8 GB. Its 432.0 GB/s bandwidth is 1.5 times the RX 9050's 288.0 GB/s. Its 6,144 shading units dwarf the RX 9050's 1,024. Its 192 TMUs triple the RX 9050's 64. Its 96 ROPs exceed the RX 9050's 64 by half. Its 384.0 GTexel/s texture rate is 2.3 times the RX 9050's 166.4 GTexel/s. Its 49.15 TFLOPS FP16 performance is 4.6 times the RX 9050's 10.65 TFLOPS.

The LX ULTRA also has a higher pixel rate: 192.0 GPixel/s versus 166.4 GPixel/s, a 15.4% advantage. Its dimensions are recorded as 268 mm in length, 112 mm in height, and 40 mm in width. The RX 9050 has no recorded dimensions, so physical size comparison is not possible from the data.

Architecture Differences

The two cards are built on fundamentally different architectures. The AMD Radeon RX 9050 uses RDNA 4.0, the latest iteration of AMD's Radeon DNA architecture. The Lisuan Tech LX ULTRA uses an architecture labeled TrueGPU, which has no lineage recorded in the database. The RX 9050 is part of the Navi IV (RX 9000) generation, with a predecessor in Navi III. The LX ULTRA is part of the 7G100 generation, with no predecessor listed.

Manufacturing processes diverge significantly. The RX 9050 is fabricated on a 4 nm process at TSMC, with a die size of 199 mm² and 29,700 million transistors. The LX ULTRA is fabricated on a 6 nm process at TSMC, with its transistor count and die size marked as unknown. The RX 9050 achieves a transistor density of 149.2M per mm², a figure that reflects the smaller process node. The LX ULTRA has no density figure recorded.

Ray tracing hardware is present on the RX 9050, with 16 dedicated RT cores. The LX ULTRA has no RT core count recorded. Neither card has tensor cores listed in the database. The RX 9050's FP16 performance is 1:1 with its FP32 performance, both at 10.65 TFLOPS. The LX ULTRA's FP16 performance is 2:1 with its FP32 performance, at 49.15 TFLOPS versus 24.58 TFLOPS. This indicates the LX ULTRA has a dedicated FP16 path that doubles throughput, while the RX 9050 treats FP16 and FP32 as equal.

Memory architecture differs in width and capacity. The RX 9050 uses a 128-bit bus with 8 GB of GDDR6. The LX ULTRA uses a 192-bit bus with 24 GB of GDDR6. The resulting bandwidths are 288.0 GB/s for the RX 9050 and 432.0 GB/s for the LX ULTRA. The memory clock itself is identical at 2250 MHz, so the bandwidth difference comes purely from the wider bus on the LX ULTRA.
