AMD Radeon 820M vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The recorded data splits these two GPUs into entirely different performance classes. The AMD Radeon 820M is an integrated graphics processor (IGP) with a 15 W TDP, designed for portable devices where power efficiency and compactness take priority. The Lisuan Tech LX PRO is a dual-slot discrete graphics card with a 225 W TDP, a 1x 16-pin power connector, and a suggested 550 W power supply, built for maximum throughput in desktop systems.

Benchmark results are not available in the database for either product, so direct performance comparisons cannot be drawn from recorded measurements. However, the specification sheets reveal where each one wins by design. The AMD Radeon 820M wins in power consumption, requiring only 15 W versus 225 W for the LX PRO. It also wins in physical footprint, being an IGP with no slot width, no power connectors, and no dimensions recorded, whereas the LX PRO occupies a dual-slot design measuring 248 mm in length, 118 mm in height, and 48 mm in width.

The Lisuan Tech LX PRO wins in raw compute resources. It carries 6144 shading units, 192 texture mapping units, and 96 raster operation pipelines, compared to the 820M's 128 shading units, 8 TMUs, and 4 ROPs. The LX PRO also has dedicated memory: 24 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth, while the 820M relies on system shared memory with bandwidth that is system dependent. The LX PRO delivers 24.58 TFLOPS of FP32 performance and 49.15 TFLOPS of FP16 performance, whereas the 820M delivers 716.8 GFLOPS for both FP32 and FP16 at a 1:1 ratio. The LX PRO's pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s dwarf the 820M's 11.20 GPixel/s and 22.40 GTexel/s.

The Radeon 820M wins on interface compatibility with Vulkan 1.4 support, while the LX PRO supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The 820M uses a PCIe 4.0 x8 bus interface, while the LX PRO uses PCIe 4.0 x16. The 820M has 2 ray tracing cores, while the LX PRO lists no ray tracing cores in its specifications.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Radeon 820M uses the RDNA 3.5 architecture, built on a 4 nm process at TSMC, and belongs to the Navi III IGP generation for Strix Point Mobile. Its chip is labeled Krackan Point 2. The Lisuan Tech LX PRO uses a TrueGPU architecture, built on a 6 nm process also at TSMC, and belongs to the 7G100 generation with a chip labeled 7G105.

Process node differences favor the AMD part: 4 nm versus 6 nm, which typically indicates higher transistor density and better power efficiency per area, though the database does not record transistor counts or die sizes for either product. Both use TSMC as the foundry.

Compute architecture differs substantially in organization. The Radeon 820M has 128 shading units, 8 TMUs, and 4 ROPs, with a 1:1 FP16 to FP32 ratio. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs, with a 2:1 FP16 to FP32 ratio, meaning its FP16 throughput (49.15 TFLOPS) is exactly double its FP32 throughput (24.58 TFLOPS). The 820M's FP16 and FP32 throughput are identical at 716.8 GFLOPS.

Memory architecture is a major differentiator. The 820M uses system shared memory with no dedicated VRAM, a system-dependent bus width, and a system-dependent bandwidth figure. The LX PRO has 24 GB of dedicated GDDR6 memory on a 192-bit bus, with memory clocks at 2250 MHz (18 Gbps effective) and a fixed bandwidth of 432.0 GB/s.

The LX PRO includes 4x DisplayPort 1.4a outputs for multi-monitor setups, while the 820M's display outputs are listed as portable device dependent. The LX PRO uses a 1x 16-pin power connector, while the 820M requires no power connectors. The LX PRO's TDP of 225 W is exactly 15 times the 820M's 15 W TDP. The 820M has 2 ray tracing cores; the LX PRO has none listed. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the 820M supports Vulkan 1.4 versus the LX PRO's Vulkan 1.3.

The Verdict

The data indicates a clear split between these two products for different use cases. The AMD Radeon 820M is an integrated solution for portable devices, with a 15 W TDP, no power connectors, no slot width, and system shared memory. It is designed for systems where the GPU shares the system's memory and power budget. Its release date is 2025-02-28, and it has 2 ray tracing cores, which the LX PRO lacks.

The Lisuan Tech LX PRO is a high-throughput discrete card for desktop systems. Its 24 GB of GDDR6 memory, 192-bit bus, 432.0 GB/s bandwidth, and 24.58 TFLOPS FP32 performance place it in a category for compute-heavy workloads, high-resolution rendering, or large dataset processing. Its 225 W TDP, 1x 16-pin power connector, suggested 550 W power supply, and dual-slot form factor confirm it is meant for a full desktop build with adequate cooling and power delivery.

The 820M's FP32 throughput of 716.8 GFLOPS is roughly 3% of the LX PRO's 24.58 TFLOPS. The LX PRO's texture rate of 384.0 GTexel/s is about 17 times the 820M's 22.40 GTexel/s. The LX PRO's pixel rate of 192.0 GPixel/s is about 17 times the 820M's 11.20 GPixel/s. These ratios show that the LX PRO is designed for workloads that saturate memory bandwidth and parallel compute units, while the 820M is designed for basic graphics acceleration in power-constrained mobile environments.

Both products are marked as Active in production status. Neither has a launch MSRP recorded, and neither has benchmark scores or nearest rivals in the database. The percentile vs all GPUs is 50 for both, but with zero average benchmark scores, that percentile carries no comparative weight.
