AMD Radeon 8040S vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the Lisuan Tech LX 7G100 has no benchmark entries in the database, while the AMD Radeon 8040S has a full set of PassMark results. The Radeon 8040S scores 10,578 in PassMark G3D, 5,138 in GPU Compute, 1,052 in G2D, 134 in DirectX 9, 80 in DirectX 11, 48 in DirectX 10, and 47 in DirectX 12. Its average benchmark score sits at 2,440, placing it in the 17th percentile of all GPUs.

Without any recorded scores for the LX 7G100, the head-to-head cannot be quantified directly. However, the specification data allows for a theoretical projection. The LX 7G100 delivers 24.58 TFLOPS of FP32 performance versus 5.734 TFLOPS for the Radeon 8040S, a 4.3x difference. The pixel rate for the LX 7G100 is 192.0 GPixel/s versus 89.60 GPixel/s, and the texture rate is 384.0 GTexel/s versus 179.2 GTexel/s. These raw throughput figures suggest the LX 7G100 would dominate in any compute-heavy or fill-rate-bound workload, though the absence of actual benchmark data means this remains speculative.

The Radeon 8040S has near-rival data that provides context. It sits 0.3% above the NVIDIA GeForce 710M (2,433 average score), 0.6% above the Intel HD Graphics 610 (2,425), and 0.7% above the NVIDIA GeForce GT 710M (2,422). It trails the AMD Radeon RX 7400 by 1.1% (2,467 average score). These deltas are small, indicating the Radeon 8040S competes with entry-level discrete GPUs from several generations ago. The LX 7G100, with its 50th percentile ranking, would presumably land far higher, but no rival comparisons exist to anchor that expectation.

The Verdict

The data shows two fundamentally different products. The AMD Radeon 8040S is an integrated graphics processor (IGP) with a 55 W TDP, designed for portable devices where power efficiency and space are critical. Its benchmark scores place it in the bottom quartile of all GPUs, but it delivers playable performance for light workloads. The Lisuan Tech LX 7G100 is a dual-slot, 225 W discrete card with 12 GB of dedicated GDDR6 memory, a 192-bit bus, and 432.0 GB/s of bandwidth. Its FP32 throughput is over four times higher, and its pixel rate is more than double.

For users who need sustained rendering performance, high-resolution textures, or compute throughput, the LX 7G100 is the clear choice based on specifications alone. For users constrained by power budgets, chassis size, or the need for a zero-maintenance integrated solution, the Radeon 8040S makes sense. The Radeon 8040S uses system-shared memory, making its bandwidth dependent on the host platform, while the LX 7G100 has dedicated memory with fixed bandwidth. The Radeon 8040S also supports PCIe 5.0 x16, whereas the LX 7G100 uses PCIe 4.0 x16, though this matters less for gaming than for data transfer.

The LX 7G100 has no benchmark entries, so its real-world performance cannot be validated against the database. The Radeon 8040S, by contrast, has a complete record. Any purchase decision involving the LX 7G100 carries uncertainty that the Radeon 8040S does not.

Where Each One Wins

The AMD Radeon 8040S wins in power efficiency, holding a 55 W TDP versus 225 W for the LX 7G100. It also wins on integration, requiring no power connectors and occupying no expansion slot, as it is an IGP. Its PCIe 5.0 x16 interface provides double the bandwidth of the LX 7G100's PCIe 4.0 x16, which benefits data-heavy workloads if the system memory can keep up.

The Lisuan Tech LX 7G100 wins decisively on raw compute. Its 24.58 TFLOPS FP32 is 4.3x the Radeon 8040S's 5.734 TFLOPS. Its FP16 throughput of 49.15 TFLOPS (2:1 ratio) vastly exceeds the Radeon 8040S's 5.734 TFLOPS (1:1 ratio), making it more suitable for AI inference or scientific calculations that use reduced precision. The LX 7G100 also has 6,144 shading units versus 1,024, 192 texture mapping units versus 64, and 96 render output units versus 32. Its 12 GB of GDDR6 memory with 432.0 GB/s bandwidth eliminates any reliance on system RAM, which is a major advantage for texture-heavy games or large datasets.

The LX 7G100 supports four DisplayPort 1.4a outputs, enabling multi-monitor setups, while the Radeon 8040S's display outputs are portable-device dependent. The LX 7G100 is dual-slot and 294 mm long, so it fits standard desktop cases, but requires a 550 W suggested power supply and one 8-pin connector. The Radeon 8040S needs none of that.

Architecture Differences

The AMD Radeon 8040S uses the RDNA 3.5 architecture on a 4 nm TSMC process, with a die size of 308 mm². It belongs to the Navi Mobile (RX 8000M) generation and is built on the Strix Halo chip. The architecture includes 16 ray tracing cores, which the LX 7G100 does not list. The Radeon 8040S has a 1:1 FP16 to FP32 ratio, meaning it processes half-precision at the same rate as single-precision.

The Lisuan Tech LX 7G100 uses a different design called TrueGPU, built on a 6 nm TSMC process. Its chip is the 7G106, and it belongs to the 7G100 generation. It has no listed ray tracing cores, and its FP16 throughput is double its FP32 throughput (49.15 TFLOPS versus 24.58 TFLOPS), indicating a 2:1 ratio. This suggests the TrueGPU architecture is optimized for workloads that benefit from half-precision math, such as machine learning or certain media processing tasks.

The Radeon 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz, while the LX 7G100 has no listed clocks. The Radeon 8040S uses RDNA 3.5's unified shader design with 1,024 shading units. The LX 7G100 has 6,144 shading units, which is six times more, along with 192 TMUs and 96 ROPs versus 64 TMUs and 32 ROPs for the Radeon 8040S. The Radeon 8040S's predecessor is Polaris Mobile, while the LX 7G100 has no listed predecessor.

Specification Differences

The most obvious difference is memory. The Radeon 8040S uses system-shared memory, with no dedicated VRAM, while the LX 7G100 has 12 GB of GDDR6 on a 192-bit bus delivering 432.0 GB/s. The Radeon 8040S's memory clock is listed as system shared, while the LX 7G100's memory runs at 2250 MHz with 18 Gbps effective speed.

Power delivery differs substantially. The Radeon 8040S is an IGP with a 55 W TDP, no power connectors, and a single slot width. The LX 7G100 is a dual-slot card with a 225 W TDP, one 8-pin power connector, and a 550 W suggested power supply. Physical dimensions also differ: the LX 7G100 measures 294 mm in length, 120 mm in height, and 49 mm in width, while the Radeon 8040S has no listed dimensions because it is integrated.

The bus interface differs: the Radeon 8040S uses PCIe 5.0 x16, while the LX 7G100 uses PCIe 4.0 x16. Display outputs are portable device dependent for the Radeon 8040S, but the LX 7G100 has four DisplayPort 1.4a outputs. The Radeon 8040S supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. Both support DirectX 12 Ultimate and OpenGL 4.6. The Radeon 8040S was released on January 5, 2025, while the LX 7G100 has a release date of June 17, 2026.
