AMD Radeon 780M vs Lisuan Tech LX PRO Comparison

The AMD Radeon 780M and the Lisuan Tech LX PRO occupy entirely different positions in the hardware landscape. The 780M is an integrated graphics processor embedded within AMD’s Phoenix chips, designed for power-efficient mobile and compact systems. The LX PRO is a standalone dual-slot discrete graphics card from Lisuan Tech, built around the 7G105 chip with a TrueGPU architecture. The database records show a fundamental split: the 780M draws from a 15 W power envelope and relies on system memory, while the LX PRO operates at 225 W with its own dedicated 24 GB GDDR6 frame buffer. The recorded benchmarks for the 780M place it in the 61st percentile of all GPUs with an average score of 17588, while the LX PRO has no recorded benchmark scores and sits at the 50th percentile by default. This analysis examines what each component delivers based strictly on the available data.

Where Each One Wins

The AMD Radeon 780M wins in scenarios where power efficiency and physical integration matter most. Its 15 W thermal design power is a fraction of the LX PRO’s 225 W requirement, making it suitable for systems without dedicated power connectors. The 780M’s slot width is listed as IGP, meaning it occupies no expansion slot, and its display outputs are motherboard dependent. This component is designed for laptops, mini PCs, and other compact builds where a discrete card cannot fit. The 780M also benefits from a newer process node at 4 nm versus the LX PRO’s 6 nm, both fabricated by TSMC. The 780M’s RDNA 3.0 architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the LX PRO matches the DirectX and OpenGL versions but trails with Vulkan 1.3.

The Lisuan Tech LX PRO wins decisively in raw compute throughput and memory bandwidth. Its FP32 performance is recorded at 24.58 TFLOPS, nearly three times the 780M’s 8.909 TFLOPS. The LX PRO’s FP16 output is 49.15 TFLOPS with a 2:1 ratio, while the 780M delivers 8.909 TFLOPS at a 1:1 ratio. The LX PRO’s dedicated 24 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, a figure the 780M cannot approach because its memory bandwidth is system dependent. The LX PRO also has more shading units (6144 versus 768), more texture mapping units (192 versus 48), and more raster operation units (96 versus 32). Its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s dwarf the 780M’s 92.80 GPixel/s and 139.2 GTexel/s. For workloads that saturate compute units, such as rendering, simulation, or machine learning inference, the LX PRO holds a clear advantage.

The 780M wins on interface flexibility in one specific regard: it uses PCIe 4.0 x8, while the LX PRO uses PCIe 4.0 x16. The wider x16 interface on the LX PRO provides double the lanes for data transfer, which benefits high-bandwidth workloads. However, the 780M’s x8 interface is adequate for its system-shared memory model. The LX PRO’s display outputs are fixed at 4x DisplayPort 1.4a, whereas the 780M’s outputs depend entirely on the motherboard implementation. This makes the 780M more adaptable to varied system designs, but the LX PRO offers a known, consistent output configuration.

The Verdict

The data indicates that the AMD Radeon 780M is the correct choice for users who need graphics capability inside a power-constrained, space-limited system. Its 15 W TDP requires no auxiliary power connectors, and its IGP slot width means no physical expansion slot is consumed. The 780M’s recorded benchmarks show it performing near the level of discrete GPUs like the AMD Radeon Pro 560 and the NVIDIA GeForce RTX 4060, with an average score of 17588. Its percentile rank of 61 places it above the median of all GPUs in the database. This component delivers usable 3D performance for everyday tasks, light gaming, and media acceleration without the thermal and spatial demands of a dedicated card.

The Lisuan Tech LX PRO is the choice for workloads that demand maximum compute throughput and dedicated memory. Its 24.58 TFLOPS FP32 performance and 432.0 GB/s bandwidth put it in a different performance class entirely. The 225 W TDP and 1x 16-pin power connector requirement indicate a system designed for high sustained loads. The suggested 550 W power supply further reinforces that this is a component for a full desktop build, not a compact system. The LX PRO’s dual-slot design and 248 mm length confirm its physical footprint. Users who prioritize raw performance over efficiency and who have the chassis space and power delivery to support it should select the LX PRO.

Neither component serves as a direct replacement for the other. The 780M’s strength is its integration and efficiency, while the LX PRO’s strength is its absolute performance. The database records no head-to-head benchmarks between these two, and the LX PRO has no individual benchmark scores, so direct performance comparisons rely solely on the specification sheets. Based on those specifications, the LX PRO is the superior choice for compute-heavy applications, and the 780M is the superior choice for portable or low-power systems.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the AMD Radeon 780M versus the Lisuan Tech LX PRO. The wins count for each is zero. However, the 780M has three recorded benchmark scores that can be examined, while the LX PRO has none. The 780M scores 480 in 3DMark Steel Nomad DX12, 18602 in Geekbench OpenCL, and 33683 in Geekbench Vulkan. These scores contribute to its average of 17588. The LX PRO’s average benchmark score is recorded as 0, which reflects the absence of test data rather than actual performance.

The nearest rivals for the 780M provide context for its standing. The AMD Radeon Pro 560 has an average score of 17551, which is 0.2% behind the 780M. The NVIDIA GeForce RTX 4060 averages 17639, putting it 0.3% ahead of the 780M. The AMD Radeon HD 7790 averages 17666, 0.4% ahead. The AMD Radeon Pro 460 averages 17509, 0.5% behind. These margins are all within one percentage point, indicating that the 780M sits in a tightly contested performance band. The 780M’s 61st percentile ranking reflects this competitive position.

Specification comparisons reveal where the LX PRO’s advantages are largest. The LX PRO’s FP32 output of 24.58 TFLOPS is 175.9% higher than the 780M’s 8.909 TFLOPS. The LX PRO’s texture rate of 384.0 GTexel/s is 175.8% higher than the 780M’s 139.2 GTexel/s. The pixel rate difference is smaller but still substantial: 192.0 GPixel/s versus 92.80 GPixel/s, a 106.9% advantage for the LX PRO. Memory bandwidth shows the most extreme gap: the LX PRO’s 432.0 GB/s is not directly comparable to the 780M’s system-dependent bandwidth, but the dedicated GDDR6 implementation gives the LX PRO a structural advantage that the 780M cannot match.

The 780M’s boost clock of 2900 MHz is noteworthy compared to the LX PRO, which has no recorded base or boost clock. The 780M’s high boost clock partially compensates for its lower core count, but the sheer number of shading units on the LX PRO (6144 versus 768) creates an eightfold difference in parallel compute capacity. The LX PRO’s 192 TMUs and 96 ROPs versus the 780M’s 48 TMUs and 32 ROPs further widen the gap in texturing and rasterization throughput.

Architecture Differences

The AMD Radeon 780M is built on the RDNA 3.0 architecture and belongs to the Navi III IGP generation with the Phoenix chip. It uses a 4 nm process node from TSMC and contains 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The architecture includes 12 ray tracing cores, a feature the LX PRO does not list. The 780M’s FP16 performance is recorded at a 1:1 ratio with FP32, meaning it processes half-precision and single-precision operations at the same rate. This is typical for RDNA-based integrated graphics.

The Lisuan Tech LX PRO uses the TrueGPU architecture with the 7G105 chip and belongs to the 7G100 generation. It is fabricated on a 6 nm process node from TSMC, and its transistor count and die size are listed as unknown. The TrueGPU architecture does not specify ray tracing cores or tensor cores in the database. The LX PRO’s FP16 performance is recorded at a 2:1 ratio with FP32, meaning it processes half-precision operations at twice the rate of single-precision. This suggests the architecture is optimized for workloads that can leverage reduced precision, such as certain AI or compute tasks.

The 780M is an integrated graphics processor, which means it shares the system’s memory and has no dedicated frame buffer. Its memory type is listed as system shared, and its bandwidth is system dependent. The LX PRO, by contrast, is a discrete card with its own 24 GB GDDR6 memory. This architectural difference has profound implications for memory latency and bandwidth. The LX PRO’s 432.0 GB/s bandwidth is fixed and dedicated, while the 780M’s bandwidth fluctuates based on the host system’s memory configuration.

The 780M’s IGP form factor means it has no slot width, no power connectors, and no dimensions recorded. The LX PRO is a dual-slot card with a 248 mm length, 118 mm height, and 48 mm width. The LX PRO uses PCIe 4.0 x16, while the 780M uses PCIe 4.0 x8. The process node difference (4 nm versus 6 nm) gives the 780M a transistor density advantage, but the LX PRO compensates with a much larger core configuration.

Specification Differences

The most significant specification differences between the two components are in core counts and memory. The 780M has 768 shading units, 48 TMUs, and 32 ROPs. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs. This represents an eightfold increase in shading units and a fourfold increase in TMUs and ROPs. The LX PRO also has 12 ray tracing cores listed for the 780M, while the LX PRO has none recorded.

Clock speeds differ substantially. The 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The LX PRO has no recorded base or boost clocks. Instead, its memory clock is listed at 2250 MHz with 18 Gbps effective. The 780M’s memory clock is not specified because it uses system shared memory.

The power specifications are starkly different. The 780M has a TDP of 15 W and no power connectors. The LX PRO has a TDP of 225 W, requires a 1x 16-pin power connector, and has a suggested power supply of 550 W. The 780M is an IGP with no slot width, while the LX PRO is dual-slot. The bus interface differs as well: PCIe 4.0 x8 for the 780M versus PCIe 4.0 x16 for the LX PRO.

Display outputs are another differentiator. The 780M’s outputs are motherboard dependent, meaning the manufacturer decides what ports are available. The LX PRO provides 4x DisplayPort 1.4a outputs. The API support is nearly identical, with both supporting DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the 780M supports Vulkan 1.4 while the LX PRO supports Vulkan 1.3.

The release dates also differ. The 780M was released on January 30, 2024, while the LX PRO has a release date of March 16, 2026. The 780M has a recorded predecessor and successor in the Navi II IGP and Navi III IGP, respectively. The LX PRO has no predecessor or successor recorded. The 780M’s transistor count is known at 25,390 million, while the LX PRO’s is unknown. The 780M’s die size is 178 mm², while the LX PRO’s is unknown. These missing data points for the LX PRO limit the depth of architectural comparison, but the recorded specifications still show a clear performance hierarchy.
