AMD Radeon 8040S vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results for the AMD Radeon 8040S and the Lisuan Tech LX ULTRA. The recorded data for the Radeon 8040S includes seven PassMark tests, while the LX ULTRA has no benchmark entries at all. This absence of direct comparison data means the analysis must rely on the Radeon 8040S's own scores and the LX ULTRA's architectural specifications.

The Radeon 8040S shows an average benchmark score of 2440 across all tests, placing it in the 17th percentile of all GPUs. Its nearest rivals in the database are clustered tightly around this figure: the NVIDIA GeForce 710M averages 2433 (0.3% ahead), the Intel HD Graphics 610 averages 2425 (0.6% ahead), the NVIDIA GeForce GT 710M averages 2422 (0.7% ahead), and the AMD Radeon RX 7400 averages 2467 (1.1% ahead of the 8040S). These deltas are minimal, indicating the 8040S sits at the very edge of a performance tier shared with older entry-level discrete GPUs and integrated graphics.

Within its own test suite, the Radeon 8040S delivers its strongest result in the PassMark G3D test with a score of 10578. The G2D test returns 1052, while the compute test scores 5138. Legacy DirectX tests show a wide spread: DirectX 9 scores 134, DirectX 11 scores 80, and both DirectX 10 and DirectX 12 score 48 and 47 respectively. The disparity between the G3D score and the DirectX 11 score suggests the GPU's driver or hardware handles modern workloads far better than legacy API paths, a pattern consistent with newer architectures.

The Lisuan Tech LX ULTRA has no recorded benchmark scores, an average benchmark score of zero, and no nearest rival entries. Its percentile ranking of 50 is listed, but without any actual test data, this ranking cannot be verified against measured performance. The database shows zero wins for either product in head-to-head comparisons, which is consistent with the lack of any comparative test results.

Architecture Differences

The two GPUs diverge fundamentally in nearly every architectural parameter. The AMD Radeon 8040S uses the Strix Halo chip built on RDNA 3.5 architecture, fabricated on a 4 nm process at TSMC with a die size of 308 mm². It belongs to the Navi Mobile (RX 8000M) generation. The Lisuan Tech LX ULTRA uses the 7G105 chip with TrueGPU architecture, built on a 6 nm process also at TSMC, with die size listed as unknown, and belongs to the 7G100 generation.

The Radeon 8040S is an integrated graphics processor (IGP) with a 55 W TDP, no power connectors, and a slot width of IGP. It uses system-shared memory with system-dependent bandwidth. The LX ULTRA is a dual-slot discrete card with a 225 W TDP, requiring one 16-pin power connector and a suggested 550 W power supply. It features 24 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s bandwidth with memory clocked at 2250 MHz (18 Gbps effective).

The shader configuration differs dramatically. The Radeon 8040S has 1024 shading units, 64 texture mapping units, and 32 ROPs, along with 16 ray tracing cores. The LX ULTRA has 6144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing cores listed. This six-fold difference in shading units and three-fold differences in TMUs and ROPs indicate the LX ULTRA is designed for raw rasterization throughput rather than ray tracing capability.

Compute throughput shows a similar gulf. The Radeon 8040S delivers 5.734 TFLOPS FP32 and 5.734 TFLOPS FP16 (1:1 ratio). The LX ULTRA delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). The LX ULTRA's FP16 rate is more than eight times higher than the 8040S's, and its FP32 rate is over four times higher. Pixel rate for the 8040S is 89.60 GPixel/s with a texture rate of 179.2 GTexel/s; the LX ULTRA reaches 192.0 GPixel/s and 384.0 GTexel/s.

The bus interfaces also differ: the Radeon 8040S uses PCIe 5.0 x16, while the LX ULTRA uses PCIe 4.0 x16. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the Radeon 8040S supports Vulkan 1.4 while the LX ULTRA supports Vulkan 1.3. Display outputs for the 8040S are listed as portable device dependent, whereas the LX ULTRA has four DisplayPort 1.4a outputs.

Where Each One Wins

Based on the recorded data, the AMD Radeon 8040S wins in the integrated form factor category. It operates at a 55 W TDP with no external power connectors, making it suitable for portable devices where space and power are constrained. Its PCIe 5.0 x16 interface provides a newer bus standard, and its Vulkan 1.4 support is ahead of the LX ULTRA's Vulkan 1.3. The 8040S also offers ray tracing cores, a feature entirely absent from the LX ULTRA's specifications.

The Radeon 8040S additionally wins on process node efficiency, using a 4 nm process compared to the LX ULTRA's 6 nm process. Its 308 mm² die size is known, whereas the LX ULTRA's die size is not recorded. The 8040S also has a release date of January 5, 2025, earlier than the LX ULTRA's March 16, 2026 date, and it has a listed predecessor (Polaris Mobile) while the LX ULTRA has none.

The Lisuan Tech LX ULTRA wins decisively in raw compute and memory specifications. Its 24.58 TFLOPS FP32 is over four times the 8040S's 5.734 TFLOPS. Its 24 GB GDDR6 memory with 432.0 GB/s bandwidth contrasts sharply with the 8040S's system-shared memory. The LX ULTRA's dual-slot form factor, four DisplayPort outputs, and 268 mm length indicate a desktop-oriented design. Its 192-bit memory bus, 96 ROPs, and 192 TMUs all exceed the 8040S's corresponding specifications by significant margins.

The data shows no benchmark wins for either product because no comparative tests exist. The LX ULTRA's 50th percentile ranking, despite having no benchmark scores, suggests the database may have an incomplete or estimated ranking for this product. The Radeon 8040S's 17th percentile ranking is based on actual measured scores.

Specification Differences

The two products differ across every major specification category. The Radeon 8040S uses RDNA 3.5 architecture on a 4 nm TSMC process; the LX ULTRA uses TrueGPU architecture on a 6 nm TSMC process. The 8040S has a 308 mm² die size; the LX ULTRA's die size is unknown. The 8040S has no transistors listed, and neither does the LX ULTRA.

Clock specifications diverge completely. The 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz. The LX ULTRA has no base or boost clock listed, only a memory clock of 2250 MHz (18 Gbps effective). The 8040S's memory is system shared; the LX ULTRA has 24 GB GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth.

Shader resources differ by multiples: 1024 vs 6144 shading units, 64 vs 192 TMUs, 32 vs 96 ROPs. The 8040S has 16 ray tracing cores; the LX ULTRA has none listed. FP32 performance is 5.734 vs 24.58 TFLOPS; FP16 is 5.734 (1:1) vs 49.15 (2:1) TFLOPS. Pixel rate is 89.60 vs 192.0 GPixel/s; texture rate is 179.2 vs 384.0 GTexel/s.

Power and physical specifications show the form factor split. The 8040S has a 55 W TDP with IGP slot width and no power connectors. The LX ULTRA has a 225 W TDP, dual-slot width, one 16-pin power connector, and a suggested 550 W power supply. The LX ULTRA measures 268 mm by 112 mm by 40 mm; the 8040S has no dimensions listed.

The bus interfaces differ (PCIe 5.0 x16 for the 8040S, PCIe 4.0 x16 for the LX ULTRA). Display outputs are portable device dependent for the 8040S and four DisplayPort 1.4a for the LX ULTRA. API support is nearly identical, with both listing DirectX 12 Ultimate (12_2) and OpenGL 4.6, but Vulkan differs (1.4 vs 1.3). Release dates are January 5, 2025 for the 8040S and March 16, 2026 for the LX ULTRA. The 8040S lists a predecessor (Polaris Mobile); the LX ULTRA has no predecessor or successor listed.
