AMD Radeon RX 6550M vs Lisuan Tech LX PRO Comparison

# Where Each One Wins

The AMD Radeon RX 6550M and Lisuan Tech LX PRO occupy fundamentally different positions in the benchmark database. The RX 6550M is a mobile-focused graphics processor with recorded benchmark results, while the LX PRO has no recorded benchmark scores and sits at the 50th percentile among all GPUs, compared to the RX 6550M’s 85th percentile.

Looking at the recorded data, the RX 6550M delivers an average benchmark score of 46,702 across its two measured tests. In OpenCL workloads, it scores 42,536, while in Vulkan workloads it reaches 50,867. The LX PRO has no recorded scores in either test, making direct numerical comparison impossible for those workloads. What the database shows instead is a structural comparison: the RX 6550M is designed for integrated graphics use in portable devices, with an IGP slot width and no power connectors, while the LX PRO is a dual-slot desktop card with a 16-pin power connector and a 550 W suggested PSU.

The use-case split is clear from the specifications. The RX 6550M targets thin-and-light systems where power draw is constrained to 80 W and the display output is portable device dependent. The LX PRO, with a 225 W TDP, a 248 mm length, and four DisplayPort 1.4a outputs, targets desktop workstations or tower systems that can accommodate a larger card and supply substantial power. The LX PRO’s 24 GB memory capacity and 432.0 GB/s bandwidth suggest workloads involving large datasets, whereas the RX 6550M’s 4 GB memory and 144.0 GB/s bandwidth suit more modest graphical tasks.

In terms of measured wins, the RX 6550M is the only one of the two with any benchmark entries. The database records zero wins for either part, because the LX PRO has no benchmark results to compare. The RX 6550M’s performance percentile of 85 indicates it outperforms the majority of all GPUs in the database, while the LX PRO’s 50th percentile places it at the median, though that percentile is computed without any actual benchmark scores for the LX PRO. The interpretation is that the RX 6550M has demonstrated performance data, while the LX PRO’s position relies on its specification profile alone.

# Architecture Differences

The two GPUs come from different architectural lineages. The RX 6550M uses AMD’s RDNA 2.0 architecture on the Navi 24 chip, part of the Navi Mobile (RX 6000M) generation. The LX PRO uses an architecture labeled TrueGPU on the 7G105 chip, belonging to the 7G100 generation. Both are fabricated on a 6 nm process at TSMC, which is a point of similarity, but the underlying design philosophies diverge sharply.

The RX 6550M packs 5,400 million transistors into a 107 mm² die, yielding a transistor density of 50.5 million per square millimeter. The LX PRO’s transistor count and die size are recorded as unknown in the database, so no density figure exists. The RX 6550M is built around 1,024 shading units, 64 texture mapping units, and 32 render output units. It also includes 16 ray tracing cores. The LX PRO scales far higher: 6,144 shading units, 192 texture mapping units, and 96 render output units. The LX PRO’s ray tracing core count is not recorded.

Memory architecture separates the two even further. The RX 6550M uses a 64-bit memory bus with 4 GB of GDDR6 memory and 144.0 GB/s bandwidth. The LX PRO uses a 192-bit bus with 24 GB of GDDR6 memory and 432.0 GB/s bandwidth. Both run memory at 2250 MHz with 18 Gbps effective speed, but the wider bus and larger capacity give the LX PRO three times the bandwidth and six times the memory capacity.

The compute capabilities follow the same pattern. The RX 6550M delivers 5.816 TFLOPS of FP32 performance and 11.63 TFLOPS of FP16 performance with a 2:1 ratio. The LX PRO delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16, also at a 2:1 ratio. The LX PRO’s pixel rate is 192.0 GPixel/s versus 90.88 GPixel/s for the RX 6550M, and its texture rate is 384.0 GTexel/s versus 181.8 GTexel/s. In every compute metric recorded, the LX PRO is roughly four times the RX 6550M’s output, which aligns with its 6x shading unit count.

API support differs slightly. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 6550M supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. The RX 6550M uses a PCIe 4.0 x4 interface, while the LX PRO uses PCIe 4.0 x16, giving the latter four times the bus bandwidth for data transfers between CPU and GPU.

# Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two GPUs. The RX 6550M has two recorded benchmarks: a Geekbench OpenCL score of 42,536 and a Geekbench Vulkan score of 50,867. The LX PRO has zero recorded benchmark scores. Consequently, there are no direct comparison points where one part beats the other in a specific test.

What the data does show is how the RX 6550M compares to other GPUs in its neighborhood. Its average benchmark score of 46,702 places it close to several rivals. The Intel Arc A530M averages 46,614, a delta of 0.2 percent. The AMD Radeon RX 5600M averages 46,601, also a 0.2 percent delta. The NVIDIA RTX A2000 averages 46,043, which is 1.4 percent behind. The NVIDIA RTX 5880 Ada Generation averages 45,972, 1.6 percent behind. These deltas indicate that the RX 6550M sits at the top of a tight cluster, leading its nearest rivals by fractions of a percent in average score.

The Vulkan score of 50,867 is notably higher than the OpenCL score of 42,536 for the RX 6550M, a difference of roughly 19.6 percent. This suggests the architecture performs better under Vulkan’s lower-level API in the recorded tests. For the LX PRO, no such comparison exists because no scores were recorded.

The LX PRO’s theoretical specifications, however, point to substantially higher raw throughput. Its FP32 figure of 24.58 TFLOPS is 4.2 times the RX 6550M’s 5.816 TFLOPS. Its texture rate of 384.0 GTexel/s is 2.1 times the RX 6550M’s 181.8 GTexel/s. Its pixel rate of 192.0 GPixel/s is also 2.1 times the RX 6550M’s 90.88 GPixel/s. These are specification-level comparisons, not measured benchmark outcomes, so they indicate potential rather than verified performance. The database records no wins for either GPU in head-to-head tests, reflecting the absence of direct measurement data for the LX PRO.
