AMD Radeon 780M vs Lisuan Tech LX 7G100 Comparison

Where Each One Wins

The AMD Radeon 780M and Lisuan Tech LX 7G100 occupy completely different segments of the GPU spectrum, and the benchmark data reflects this split clearly. The Radeon 780M is an integrated graphics processor built for the Phoenix chip, designed to operate within a 15 W TDP envelope. Its recorded measurements show an average benchmark score of 17,588 across three tests, placing it at the 61st percentile of all GPUs in the database. The Lisuan Tech LX 7G100, by contrast, is a dual-slot discrete card with a 225 W TDP, 12 GB of dedicated GDDR6 memory, and a 192-bit memory bus. However, the LX 7G100 has no recorded benchmark scores in the database, which means its wins cannot be quantified through direct measurement data.

The Radeon 780M wins in every category where actual measurements exist. Its 3DMark Steel Nomad DX12 score of 480, Geekbench OpenCL score of 18,602, and Geekbench Vulkan score of 33,683 provide concrete data points. The LX 7G100 has zero entries in the benchmark database, so any comparison of measured performance is impossible. The use-case split therefore becomes a matter of architectural intent rather than measured outcomes. The 780M delivers its performance within an integrated form factor, consuming 15 W and requiring no power connectors, making it suitable for compact systems where the CPU handles most processing and the GPU provides supplementary graphics capability. The LX 7G100, with its 225 W TDP, 1x 8-pin power connector, and 550 W suggested PSU, targets discrete graphics workloads where dedicated memory and higher throughput matter more than power efficiency.

The LX 7G100 wins on paper specifications that suggest higher raw throughput. Its FP32 compute of 24.58 TFLOPS dwarfs the 780M's 8.909 TFLOPS. Its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s exceed the 780M's 92.80 GPixel/s and 139.2 GTexel/s respectively. The 12 GB GDDR6 memory with 432.0 GB/s bandwidth stands against the 780M's system-shared memory with system-dependent bandwidth. These figures indicate the LX 7G100 was designed for workloads that demand sustained memory bandwidth and high compute throughput, while the 780M was designed for efficiency within an integrated power budget.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between these two GPUs, and the LX 7G100 has no standalone benchmark scores recorded at all. The comparison therefore relies on the Radeon 780M's measured results and the architectural specifications of both parts.

The Radeon 780M's Geekbench Vulkan score of 33,683 represents its strongest recorded result, nearly double its Geekbench OpenCL score of 18,602. The Vulkan result indicates the RDNA 3.0 architecture handles low-level graphics APIs efficiently, which aligns with its 12 ray tracing cores and 768 shading units. The OpenCL score of 18,602 shows general compute capability that lands within a tight cluster of rival GPUs: the Radeon Pro 560 scores 17,551 (0.2% behind), the Radeon Pro 460 scores 17,509 (0.5% behind), the RTX 4060 scores 17,639 (0.3% ahead), and the HD 7790 scores 17,666 (0.4% ahead). This clustering indicates the 780M's compute performance is competitive with discrete GPUs from earlier generations despite being an integrated part.

The 3DMark Steel Nomad DX12 score of 480 provides a specific data point for modern DirectX 12 gaming workloads. The 780M's 61st percentile ranking among all GPUs in the database suggests it outperforms a majority of recorded GPUs, though its nearest rivals are clustered within a narrow band, indicating dense competition at this performance level.

The LX 7G100's absence from the benchmark database means its actual performance cannot be validated. Its specification sheet suggests a much higher ceiling: 24.58 TFLOPS FP32 is 2.76 times the 780M's 8.909 TFLOPS. Its 49.15 TFLOPS FP16 at 2:1 ratio indicates strong half-precision throughput for AI or compute workloads. The 432.0 GB/s memory bandwidth is a qualitative leap over the system-dependent bandwidth of the 780M, which relies on the host system's memory controller and DDR5 or LPDDR5 speeds that vary by platform.

Specification Differences

The two GPUs differ in nearly every specification category. The Radeon 780M uses a 4 nm process node from TSMC with 25,390 million transistors on a 178 mm² die, yielding a transistor density of 142.6 million per square millimeter. The LX 7G100 uses a 6 nm process node, also from TSMC, but its transistor count and die size are listed as unknown in the database, so no density figure can be calculated.

Clock speeds show a fundamental difference. The 780M has a base clock of 800 MHz and a boost clock of 2900 MHz. The LX 7G100 lists no base or boost clock, only a memory clock of 2250 MHz (18 Gbps effective). This absence of clock data for the LX 7G100 means its actual operating frequencies are not recorded.

Memory configurations are starkly different. The 780M uses system-shared memory with system-dependent bandwidth, meaning it has no dedicated VRAM. The LX 7G100 has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The memory clock for the LX 7G100 is fixed at 2250 MHz, while the 780M's memory speed depends entirely on the host system.

Compute unit counts differ substantially. The 780M has 768 shading units, 48 texture mapping units, and 32 render output units. The LX 7G100 has 6,144 shading units, 192 TMUs, and 96 ROPs. These are 8 times, 4 times, and 3 times the 780M's counts respectively. The 780M has 12 ray tracing cores, while the LX 7G100's ray tracing core count is not recorded.

Power and physical specifications also diverge. The 780M has a 15 W TDP, is an IGP with no power connectors, and uses a PCIe 4.0 x8 interface. The LX 7G100 has a 225 W TDP, is dual-slot, requires one 8-pin power connector, has a 550 W suggested PSU, and uses a PCIe 4.0 x16 interface. The LX 7G100 has four DisplayPort 1.4a outputs, while the 780M's display outputs are motherboard-dependent.

Architecture Differences

The Radeon 780M is built on AMD's RDNA 3.0 architecture, specifically the Phoenix chip within the Navi III IGP generation. It uses a 4 nm TSMC process and is classified as a Navi III IGP with the predecessor designation of Navi II IGP and successor of Navi III IGP. Its FP16 performance matches its FP32 at 8.909 TFLOPS, indicating a 1:1 ratio where half-precision and single-precision compute are equal.

The Lisuan Tech LX 7G100 uses a "TrueGPU" architecture on the 7G106 chip within the 7G100 generation. Its FP16 performance of 49.15 TFLOPS is exactly double its FP32 of 24.58 TFLOPS, indicating a 2:1 ratio where half-precision operations run at twice the rate of single-precision. This architecture choice suggests the LX 7G100 was optimized for workloads that benefit from reduced-precision arithmetic, such as machine learning inference or certain compute tasks.

The 780M supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The newer Vulkan version on the 780M may provide access to newer extension features, though the practical impact depends on driver implementation and software support.

The LX 7G100 has no recorded predecessor or successor in the database, suggesting it is either a first-generation product or the database lacks historical context for this part. The 780M has a clear lineage from Navi II IGP to Navi III IGP, indicating an established product line. The LX 7G100's manufacturer is listed as unknown, while the 780M is clearly attributed to AMD.

The Verdict

The recorded data supports only one conclusion: the AMD Radeon 780M is the only part of the two with measurable benchmark performance. Its average score of 17,588 places it at the 61st percentile of all GPUs, and its nearest rivals are all within 0.5%, indicating a competitive position among established GPUs. The 780M's 15 W TDP, integrated form factor, and system-shared memory make it suitable for systems where power efficiency and space are priorities, and its benchmark results confirm it delivers usable performance within those constraints.

The Lisuan Tech LX 7G100 cannot be evaluated through benchmark data because none exists in the database. Its specifications describe a high-end discrete GPU: 12 GB GDDR6, 432.0 GB/s bandwidth, 24.58 TFLOPS FP32, 192 TMUs, and 96 ROPs. These figures indicate a part designed for workloads that require sustained memory bandwidth and high compute throughput, but without recorded measurements, the database cannot confirm how these specifications translate into actual performance.

The choice between these two GPUs is therefore not a performance comparison but a form-factor and workload comparison. The 780M is an integrated GPU with verified benchmark scores and a 61st percentile ranking. The LX 7G100 is a discrete GPU with a 225 W TDP and a 550 W suggested PSU, designed for systems that can accommodate its dual-slot size and power requirements. The 780M belongs in systems that need graphics capability without dedicated hardware. The LX 7G100 belongs in systems that require dedicated memory and high compute throughput, assuming its unmeasured performance meets the workload's demands. The database records the 780M's performance but leaves the LX 7G100's performance unverified, so any decision involving the LX 7G100 must account for the absence of measured data.
