AMD Radeon 820M vs Lisuan Tech LX MAX Comparison

The AMD Radeon 820M and the Lisuan Tech LX MAX occupy opposite ends of the graphics spectrum, yet both are listed as active products in the database. The Radeon 820M is a 4 nm integrated graphics processor from AMD, built on the RDNA 3.5 architecture and part of the Navi III IGP generation for Strix Point Mobile. The Lisuan Tech LX MAX is a 6 nm discrete graphics card from Lisuan Tech, using the TrueGPU architecture and belonging to the 7G100 generation. The database records no direct head-to-head benchmark matches between these two parts, and each holds a 50th percentile position among all GPUs. The recorded data shows zero wins for either side in the head-to-head table, meaning the analysis must rely on the specification differences and architectural characteristics to establish relative positioning.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for the AMD Radeon 820M versus the Lisuan Tech LX MAX. The winsA and winsB fields are both zero, and the headToHeadBenchmarks array is empty. This absence of direct measurement data means the comparison must be inferred from the recorded specification fields rather than from performance scores. The Radeon 820M has an average benchmark score of zero, as does the Lisuan Tech LX MAX, and neither lists any individual benchmark entries. The percentileVsAllGpus field shows both at the 50th percentile, which indicates they sit at the median of the database distribution, but this figure does not reflect any measured performance comparison between them.

Without direct scores, the available quantitative indicators are the compute throughput values. The Radeon 820M delivers 716.8 GFLOPS of FP32 performance, while the Lisuan Tech LX MAX delivers 24.58 TFLOPS. Converting the LX MAX figure to the same unit gives 24,580 GFLOPS, which is approximately 34.3 times the Radeon 820M's output. The pixel rate shows a similar gap: the Radeon 820M reaches 11.20 GPixel/s, while the LX MAX reaches 192.0 GPixel/s, a factor of roughly 17.1. The texture rate for the Radeon 820M is 22.40 GTexel/s, versus 384.0 GTexel/s for the LX MAX, a factor of about 17.1 as well. These numbers indicate the LX MAX holds a substantial lead in raw throughput, though the absence of benchmark scores means the practical impact cannot be quantified in application-level terms.

The FP16 performance further separates the two. The Radeon 820M lists FP16 at 716.8 GFLOPS with a 1:1 ratio, meaning it processes FP16 at the same rate as FP32. The Lisuan Tech LX MAX lists FP16 at 49.15 TFLOPS with a 2:1 ratio, meaning its FP16 throughput is double its FP32 rate. In relative terms, the LX MAX delivers roughly 68.6 times the FP16 throughput of the Radeon 820M. The database does not include any measured frame rates, synthetic scores, or thermal results, so these compute figures remain the only hard numbers for comparison.

Where Each One Wins

The AMD Radeon 820M wins in categories tied to its integrated nature and low power envelope. Its power draw is recorded at 15 W, compared to 225 W for the Lisuan Tech LX MAX. The Radeon 820M uses no power connectors, while the LX MAX requires a single 16-pin connector. The Radeon 820M occupies an IGP slot width, meaning it fits directly into a processor package rather than a separate expansion slot. The Lisuan Tech LX MAX is a dual-slot card. The Radeon 820M also has a smaller process node at 4 nm versus 6 nm, which typically indicates higher transistor density per area, though the database records transistor count and die size as unknown for both parts.

The Radeon 820M supports Vulkan 1.4, while the Lisuan Tech LX MAX supports Vulkan 1.3. This gives the Radeon 820M a version advantage in the Vulkan graphics API. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, so there is no differentiation there. The Radeon 820M also has a release date earlier in the database timeline, recorded as 2025-02-28, whereas the LX MAX is dated 2026-03-16. For users prioritizing a smaller footprint, lower power consumption, and no external power requirement, the Radeon 820M is the only viable option in this pairing.

The Lisuan Tech LX MAX wins in every raw performance category recorded. It has 6144 shading units versus 128 for the Radeon 820M. It has 192 texture mapping units versus 8, and 96 render output units versus 4. The LX MAX also includes 2 ray tracing cores on the Radeon 820M side, but the LX MAX lists no ray tracing core count in its specification. The memory configuration heavily favors the LX MAX: 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s of bandwidth and a memory clock of 2250 MHz with 18 Gbps effective data rate. The Radeon 820M uses system shared memory, with the bus width and bandwidth listed as system dependent. The LX MAX supports PCIe 4.0 x16, while the Radeon 820M uses PCIe 4.0 x8, halving the available interface lanes. The LX MAX also provides four DisplayPort 1.4a outputs, while the Radeon 820M's display outputs are listed as portable device dependent.

Architecture Differences

The two products use entirely different architectures. The AMD Radeon 820M is based on RDNA 3.5, a graphics architecture from AMD, and is classified under the Navi III IGP generation for Strix Point Mobile. Its chip is designated Krackan Point 2. The Lisuan Tech LX MAX uses an architecture labeled TrueGPU, with a chip named 7G106 and a generation of 7G100. There is no shared design lineage between these two in the database.

The Radeon 820M's ray tracing capability is present, with 2 dedicated ray tracing cores. The LX MAX does not list any ray tracing cores in its specification, leaving that field null. The Radeon 820M also does not list tensor cores, and neither does the LX MAX. The compute unit organization differs significantly: the Radeon 820M has 128 shading units, 8 TMUs, and 4 ROPs, while the LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs. These are not just larger numbers; they represent a fundamentally different scale of parallel processing hardware.

The FP16 ratio differs between the two architectures. The Radeon 820M executes FP16 at a 1:1 ratio with FP32, meaning it does not have dedicated half-precision acceleration. The Lisuan Tech LX MAX executes FP16 at a 2:1 ratio, meaning its hardware can process two half-precision operations per single-precision operation. This architectural choice gives the LX MAX a distinct advantage in workloads that can utilize FP16 arithmetic, such as certain compute tasks. The process node also differs: 4 nm for the Radeon 820M and 6 nm for the LX MAX, both fabricated by TSMC. The database records transistors and die size as unknown for both, so no density comparison can be made.

The memory architecture is another major divergence. The Radeon 820M uses system shared memory, with no dedicated VRAM. Its memory clock is listed as system shared, and its bandwidth is system dependent. The LX MAX has dedicated memory: 12 GB of GDDR6, a 192-bit bus, and a fixed bandwidth of 432.0 GB/s. This means the LX MAX does not compete with the host system for memory resources, while the Radeon 820M relies on the system's main memory for both graphics and general computing.

The API support shows a slight difference in Vulkan versions. The Radeon 820M supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The higher Vulkan version on the Radeon 820M may indicate newer driver-level features, but the database does not specify which features differ between Vulkan 1.3 and 1.4 in this context.

Specification Differences

The Radeon 820M and Lisuan Tech LX MAX differ in nearly every recorded specification field. The manufacturer is AMD for the Radeon 820M and unknown for the LX MAX.

The Verdict

The data shows two products designed for different purposes. The AMD Radeon 820M fits into mobile and low-power systems as an integrated graphics solution. Its 15 W TDP, lack of power connectors, and IGP slot width make it suitable for compact devices where power and space are constrained. Its performance ceiling is low by discrete standards: 716.8 GFLOPS FP32, 11.20 GPixel/s pixel rate, and 22.40 GTexel/s texture rate. The 2 ray tracing cores and Vulkan 1.4 support provide modern API features, but the hardware scale is minimal.

The Lisuan Tech LX MAX is a high-power discrete card. Its 225 W TDP and dual-slot design require a dedicated power connection and a substantial power supply. The recorded specifications show a compute capability that is an order of magnitude higher: 24.58 TFLOPS FP32, 192.0 GPixel/s pixel rate, and 384.0 GTexel/s texture rate. The 12 GB GDDR6 memory with 432.0 GB/s bandwidth provides a fixed, high-bandwidth memory pool that does not depend on system resources.

The database does not provide any direct benchmark scores for either GPU, so the relative performance in real applications remains unmeasured. The specification gap is clear, however. The LX MAX exceeds the Radeon 820M in every raw throughput metric by factors ranging from roughly 17 (pixel and texture rate) to roughly 68 (FP16). The Radeon 820M counters with a 4 nm process node, a lower power draw, no external power requirement, and a newer Vulkan version. Users requiring substantial graphics compute for high-resolution rendering or compute workloads would select the LX MAX based on its memory capacity and throughput figures. Users constrained by power, physical space, or the need for an integrated solution would select the Radeon 820M. The data does not support any other conclusion.
