AMD Radeon 680M vs Lisuan Tech LX MAX Comparison

Head-to-Head Benchmarks

The AMD Radeon 680M and Lisuan Tech LX MAX occupy different positions in the database, with the former carrying three recorded benchmark scores and the latter having no recorded benchmark results. The head-to-head comparison is therefore limited to the available measurements for the Radeon 680M, which delivers a 3DMark Steel Nomad DX12 score of 378, a Geekbench OpenCL score of 23,468, and a Geekbench Vulkan score of 21,965.

The Lisuan Tech LX MAX has an average benchmark score of 0 in the database, reflecting the absence of any submitted or recorded test results. This places the LX MAX at the 50th percentile among all GPUs, while the Radeon 680M sits at the 57th percentile. The percentile gap indicates that the Radeon 680M ranks higher in the overall distribution of recorded GPU performance, though the LX MAX's placement is based on its default position rather than measured data.

For the Radeon 680M, the nearest rivals provide useful context. Its average benchmark score of 15,270 is essentially tied with the NVIDIA GeForce GTX 580 (15,283, a delta of -0.1%) and the NVIDIA GeForce RTX 2060 (15,290, a delta of -0.1%). The Radeon 680M edges ahead of the NVIDIA GeForce RTX 3050 OEM (15,199, a delta of 0.5%) and the AMD Radeon RX 7600 (15,171, a delta of 0.7%). These deltas are small, indicating that the Radeon 680M's performance is comparable to those desktop discrete GPUs despite being an integrated graphics processor.

When comparing the two cards directly, the LX MAX shows theoretical compute advantages based on its specification sheet, but the database contains no measurements to confirm real-world performance. The Radeon 680M's recorded scores demonstrate that it can compete with older discrete GPUs, while the LX MAX remains unverified in the benchmark database.

Where Each One Wins

The Radeon 680M wins in every measured category because it is the only card with benchmark data. Its three recorded tests span different APIs: DirectX 12 via 3DMark Steel Nomad, OpenCL via Geekbench, and Vulkan via Geekbench. The OpenCL score of 23,468 and Vulkan score of 21,965 show consistent performance across compute APIs, while the 3DMark Steel Nomad DX12 score of 378 indicates a lower result in that specific rasterization workload.

The Lisuan Tech LX MAX has no recorded wins in the database. Its specifications suggest high theoretical throughput: 24.58 TFLOPS FP32, 384.0 GTexel/s texture rate, and 192.0 GPixel/s pixel rate. These figures are substantially higher than the Radeon 680M's 3.379 TFLOPS FP32, 105.6 GTexel/s, and 70.40 GPixel/s. However, without benchmark scores, the LX MAX cannot claim a measured victory.

In terms of memory, the LX MAX offers dedicated resources: 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. The Radeon 680M uses system shared memory with bandwidth described as system dependent. For workloads that benefit from dedicated high-bandwidth memory, the LX MAX's configuration is structurally advantaged, but the database does not contain test results to quantify that advantage.

The Radeon 680M wins on portability and power characteristics. Its 50 W TDP and IGP slot width make it suitable for integrated use, whereas the LX MAX requires a dual-slot footprint, a 1x 16-pin power connector, and a 550 W suggested PSU. The Radeon 680M has no power connectors and is classified as an IGP, which gives it a clear edge in systems where power delivery and space are constrained.

Specification Differences

The two cards differ across nearly every measured specification. The Radeon 680M is manufactured by AMD using the Rembrandt+ chip on RDNA 2.0 architecture, while the LX MAX is from an unknown manufacturer using the 7G106 chip on TrueGPU architecture. Both use a 6 nm process from TSMC, but the Radeon 680M has 13,100 million transistors on a 208 mm² die, while the LX MAX has unknown transistor and die size figures.

Clock speeds differ significantly. The Radeon 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz, while the LX MAX lists no base or boost clocks. Memory clocks also differ: the LX MAX specifies 2250 MHz with 18 Gbps effective, while the Radeon 680M's memory clock is system shared.

Memory configuration is a major split. The Radeon 680M uses system shared memory with no dedicated size, type, bus width, or bandwidth figure beyond "system dependent". The LX MAX has 12 GB of GDDR6, a 192-bit bus, and 432.0 GB/s bandwidth. The bus interface also differs: PCIe 4.0 x8 for the Radeon 680M versus PCIe 4.0 x16 for the LX MAX.

Compute unit counts are substantially different. The Radeon 680M has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The LX MAX has 6144 shading units, 192 TMUs, and 96 ROPs, with no listed ray tracing cores. Pixel rates are 70.40 GPixel/s for the Radeon 680M versus 192.0 GPixel/s for the LX MAX. Texture rates are 105.6 GTexel/s versus 384.0 GTexel/s.

Power and physical dimensions differ. The Radeon 680M has a 50 W TDP, IGP slot width, and no power connectors. The LX MAX has a 225 W TDP, dual-slot width, a 1x 16-pin power connector, and dimensions of 248 mm length, 118 mm height, and 48 mm width. Display outputs also differ: portable device dependent for the Radeon 680M versus 4x DisplayPort 1.4a for the LX MAX.

The API support is similar, with both supporting DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Vulkan version differs slightly: 1.4 for the Radeon 680M and 1.3 for the LX MAX. Release dates are also different, with the Radeon 680M released on 2023-01-02 and the LX MAX on 2026-03-16.

Architecture Differences

The Radeon 680M uses RDNA 2.0 architecture on the Rembrandt+ chip, belonging to the Navi II IGP generation (Rembrandt Mobile). The LX MAX uses TrueGPU architecture on the 7G106 chip, belonging to the 7G100 generation. These are distinct architectural families with different design goals: RDNA 2.0 is a well-established GPU architecture from AMD, while TrueGPU appears to be a proprietary design from Lisuan Tech.

The Radeon 680M is an integrated graphics processor (IGP) built into a mobile platform, as indicated by its IGP slot width and portable device dependent display outputs. The LX MAX is a discrete dual-slot card with dedicated memory and multiple display outputs, suggesting a desktop-oriented design.

Both use a 6 nm process from TSMC, but the Radeon 680M has known transistor and die size figures (13,100 million and 208 mm² respectively), while the LX MAX lists both as unknown. The transistor density for the Radeon 680M is 63.0M per mm², while the LX MAX has no density figure.

Feature sets differ in ray tracing. The Radeon 680M has 12 ray tracing cores, while the LX MAX lists none. Neither card lists tensor cores. The Radeon 680M's FP16 performance is listed at 6.758 TFLOPS with a 2:1 ratio, while the LX MAX lists 49.15 TFLOPS FP16 also with a 2:1 ratio. These ratios indicate that both cards execute FP16 at twice the rate of FP32, but the LX MAX's raw throughput is much higher on paper.

Production status is active for both cards. The Radeon 680M has a predecessor (Vega II IGP) and a successor (Navi III IGP), while the LX MAX has neither listed. The Radeon 680M's release date is 2023-01-02, and the LX MAX's is 2026-03-16, making the LX MAX a later entry in the database.
