AMD Radeon RX 7800M vs Lisuan Tech LX 7G100 Comparison

The Verdict

The AMD Radeon RX 7800M is the only option with recorded performance data in the database, and it sits at the 73rd percentile among all GPUs. The Lisuan Tech LX 7G100 has no benchmark scores, an average score of zero, and sits at the 50th percentile, which indicates it has not been tested or verified by the database. The RX 7800M delivers an average benchmark score of 27883, placing it within 0.8% of the AMD FirePro S7150, within 0.5% of the NVIDIA GeForce GTX 980 Ti, and effectively tied with the AMD Radeon Pro Vega 20 at a 0.2% delta.

The Lisuan Tech LX 7G100, despite its higher shading unit count of 6144 versus 3840, has no measurable performance data. The RX 7800M is the clear choice for anyone needing verified performance, as it has ten separate benchmark scores across DirectX 9, 10, 11, 12, OpenCL, Vulkan, and compute workloads. The LX 7G100 cannot be recommended for any performance-based selection because the database contains zero measurements for it. Its 50th percentile ranking appears to be a default or unverified placeholder rather than a tested result.

The verdict is straightforward: the RX 7800M wins by default due to having actual data, while the LX 7G100 remains unproven. For users who require a working, tested GPU, the RX 7800M is the only viable option between these two. The LX 7G100 may have architectural novelty, but without recorded scores it cannot compete in any benchmark comparison.

Where Each One Wins

The AMD Radeon RX 7800M wins in every measurable category because it is the only unit with benchmark results. Its strongest recorded performance comes from the Geekbench Vulkan test with a score of 126668, followed closely by Geekbench OpenCL at 120778. The 3DMark Steel Nomad DX12 test shows a score of 2994, which confirms strong DirectX 12 capability. In Passmark tests, the RX 7800M scores 17613 in G3D, 9342 in GPU Compute, 892 in G2D, 176 in DirectX 11, 174 in DirectX 9, 99 in DirectX 10, and 89 in DirectX 12.

The Lisuan Tech LX 7G100 has no wins in any category because the database contains no benchmark scores for it. Its specifications suggest potential strengths, such as 6144 shading units and 49.15 TFLOPS FP16 performance, but these cannot be validated without test data. The LX 7G100 also supports a newer Vulkan version 1.4 compared to the RX 7800M's 1.3, which could matter for future software compatibility, but this is a feature difference rather than a performance win.

The RX 7800M wins across all workloads: legacy DirectX 9 and 10 titles, modern DirectX 11 and 12 games, compute-heavy applications, and Vulkan-based software. Its Passmark DirectX 11 score of 176 is nearly double its DirectX 10 score of 99, indicating stronger driver optimization for newer APIs. The G2D score of 892 shows decent 2D performance, though this is less relevant for gaming workloads.

Architecture Differences

The AMD Radeon RX 7800M uses the Navi 32 chip with RDNA 3.0 architecture, built on a 5 nm process at TSMC. It contains 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The LX 7G100 uses a 7G106 chip with a "TrueGPU" architecture on a 6 nm process, also from TSMC, but its transistor count and die size are listed as unknown.

The RX 7800M has 3840 shading units, 240 texture mapping units, 96 render output units, and 60 ray tracing cores. The LX 7G100 has 6144 shading units, 192 texture mapping units, and 96 render output units, but no ray tracing cores are listed. The LX 7G100 has a 1.6x higher shading unit count, yet its FP32 throughput is lower at 24.58 TFLOPS versus 35.87 TFLOPS for the RX 7800M. This indicates the RX 7800M executes FP32 operations more efficiently per shading unit, likely due to architectural differences in RDNA 3.0 versus TrueGPU.

Clock speeds differ significantly. The RX 7800M has a base clock of 1295 MHz, a boost clock of 2335 MHz, and a game clock of 2145 MHz. The LX 7G100 has no base, boost, or game clock listed. Memory clocks are identical at 2250 MHz with 18 Gbps effective speed, and both use 12 GB of GDDR6 on a 192 bit bus with 432.0 GB/s bandwidth.

The FP16 performance reveals a key architectural divergence. The RX 7800M delivers 35.87 TFLOPS FP16 with a 1:1 ratio to FP32, meaning it does not double FP16 throughput. The LX 7G100 delivers 49.15 TFLOPS FP16 with a 2:1 ratio, meaning it has dedicated FP16 capability that is twice its FP32 rate. This makes the LX 7G100 potentially stronger for workloads that leverage FP16, such as certain AI or compute tasks, but no benchmark data confirms this.

The RX 7800M has a 180 W TDP and is an integrated graphics processor (IGP) with no power connectors and no slot width. The LX 7G100 has a 225 W TDP, is a dual-slot card requiring a 1x 8-pin power connector and a 550 W suggested power supply. The LX 7G100 is a physical card measuring 294 mm in length, 120 mm in height, and 49 mm in width, while the RX 7800M's dimensions are not listed.

Both support PCIe 4.0 x16 and DirectX 12 Ultimate (12_2) with OpenGL 4.6. The RX 7800M supports Vulkan 1.4 and has display outputs that are portable device dependent. The LX 7G100 supports Vulkan 1.3 and has 4x DisplayPort 1.4a outputs.

Head-to-Head Benchmarks

The database records no head-to-head benchmark results between the AMD Radeon RX 7800M and the Lisuan Tech LX 7G100. The headToHeadBenchmarks field is empty, and the winsA and winsB counters are both zero. This means a direct comparison of measured performance is impossible.

The RX 7800M has ten individual benchmark scores that define its performance profile. Its highest score is 126668 in Geekbench Vulkan, which indicates strong Vulkan API performance for modern games and compute workloads. The Geekbench OpenCL score of 120778 shows similar strength in OpenCL-based applications. The 3DMark Steel Nomad DX12 score of 2994 is the primary DirectX 12 gaming metric, and it confirms the card can handle current-generation titles.

In Passmark testing, the RX 7800M scores 17613 in G3D, which is the overall 3D graphics performance metric. Its GPU Compute score of 9342 indicates moderate compute capability. The legacy API scores show a clear pattern: DirectX 11 at 176 and DirectX 9 at 174 outperform DirectX 10 at 99 and DirectX 12 at 89. This suggests the RX 7800M has optimized drivers for older DirectX 9 and 11 titles, while DirectX 12 performance may be limited by other factors.

The LX 7G100 has no benchmark data, so it cannot be compared directly. Its specifications suggest it might compete in specific areas, such as FP16 compute where its 49.15 TFLOPS exceeds the RX 7800M's 35.87 TFLOPS. However, without recorded scores, any head-to-head analysis is speculative. The nearest rivals to the RX 7800M are all AMD or NVIDIA cards from different eras: the Radeon Pro Vega 20 with an average score of 27839, the Radeon Pro W5500X at 27973, the GeForce GTX 980 Ti at 28020, and the FirePro S7150 at 28117. The RX 7800M's 27883 average score places it just below all except the Vega 20, which it slightly exceeds.

The RX 7800M has higher pixel rate at 224.2 GPixel/s versus 192.0 GPixel/s, and higher texture rate at 560.4 GTexel/s versus 384.0 GTexel/s. It also has more TMUs at 240 versus 192 and includes 60 ray tracing cores, which the LX 7G100 lacks entirely. The LX 7G100 compensates with 6144 shading units and a 2:1 FP16 ratio, but its lower pixel and texture rates indicate it may be less efficient in traditional rasterization workloads.

The physical form factors are completely different. The RX 7800M is an integrated graphics processor with no power connectors, designed for portable devices. The LX 7G100 is a dual-slot discrete card requiring external power, measuring 294 mm in length, 120 mm in height, and 49 mm in width. This makes the RX 7800M suitable for laptops or compact systems, while the LX 7G100 requires a full-size desktop chassis with adequate power delivery.

Both GPUs share the same memory subsystem, which is rare among competing products. The identical 12 GB GDDR6 configuration on a 192 bit bus with 432.0 GB/s bandwidth means memory capacity and bandwidth are not differentiating factors. The differences lie entirely in compute architecture, clock speeds, and power delivery.
