AMD Radeon 680M vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database contains recorded benchmark scores for only one of the two parts in this comparison. The AMD Radeon 680M has three completed tests: a 3DMark Steel Nomad DX12 result of 378, a Geekbench OpenCL score of 23,468, and a Geekbench Vulkan score of 21,965. Its average benchmark score across all recorded tests is 15,270. The Lisuan Tech LX ULTRA has no benchmark results in the database, meaning its average score is recorded as 0 and it holds no comparative percentile position.

The Radeon 680M sits at the 57th percentile among all GPUs in the database. Its nearest rivals, based on average score, are the NVIDIA GeForce GTX 580 at 15,283 (0.1% ahead), the NVIDIA GeForce RTX 2060 at 15,290 (0.1% ahead), the NVIDIA GeForce RTX 3050 OEM at 15,199 (0.5% behind), and the AMD Radeon RX 7600 at 15,171 (0.7% behind). These deltas are all within one percentage point, indicating the 680M lands in a tightly clustered performance band where a single benchmark run can shift relative placement.

Since the LX ULTRA has no recorded scores, there are no direct head-to-head comparisons to walk through. The available data instead shows a gap between a measured part and an unmeasured one. The 680M's 3DMark Steel Nomad result of 378 reflects a low-power integrated solution, while the LX ULTRA's specifications suggest a much larger discrete design, but the database has no empirical confirmation of that expectation.

The Geekbench scores for the 680M deserve attention. An OpenCL score of 23,468 and a Vulkan score of 21,965 show a modest gap between the two APIs, with OpenCL delivering about 6.8% higher throughput. That spread is consistent with driver optimization differences rather than architectural limitations. The absence of any LX ULTRA scores means no such comparison is possible.

The Verdict

The data supports a straightforward split. The AMD Radeon 680M is a verified performer with concrete benchmark results, a 57th percentile ranking, and measurable standing against established discrete GPUs. It trades within 0.7% of the Radeon RX 7600 and within 0.1% of the GeForce GTX 580 and RTX 2060 in average score. Those are real, recorded results from the database.

The Lisuan Tech LX ULTRA has no empirical record. Its average benchmark score is 0, its percentile is 50 (the default for unmeasured parts), and it has no nearest rivals listed. From a database perspective, the LX ULTRA is a specification sheet without a performance profile. Any claim about its real-world speed cannot be supported by the recorded data.

Therefore, the verdict is conditional. For anyone relying on verified measurements, the Radeon 680M is the only part with evidence. For anyone considering the LX ULTRA, the database currently offers no confirmation of its capabilities. The specifications indicate a much larger GPU, but specifications alone do not constitute benchmark results. The 680M's placement at the 57th percentile, alongside rivals like the RTX 2060 and RX 7600, gives it a concrete reference point. The LX ULTRA has none.

Architecture Differences

The AMD Radeon 680M uses the Rembrandt+ chip built on RDNA 2.0 architecture, fabricated on a 6 nm process at TSMC. It belongs to the Navi II IGP generation and is classified as an integrated graphics processor. The chip contains 13,100 million transistors on a 208 mm² die, yielding a transistor density of 63.0 million per square millimeter. The architecture includes 12 ray tracing cores, a feature the LX ULTRA does not list.

The Lisuan Tech LX ULTRA uses the 7G105 chip based on a TrueGPU architecture, also fabricated on a 6 nm process at TSMC. Its generation is listed as 7G100. The database records no transistor count, no die size, and no transistor density for this part. It also lists no ray tracing cores. Both parts support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the Radeon 680M supports Vulkan 1.4 while the LX ULTRA supports Vulkan 1.3.

The 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The LX ULTRA has no recorded base or boost clocks. Memory architecture differs fundamentally: the 680M uses system shared memory with system dependent bandwidth, while the LX ULTRA has 24 GB of dedicated GDDR6 memory on a 192 bit bus with 432.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective).

The Radeon 680M is an IGP with no power connectors and a 50 W TDP. The LX ULTRA is a dual-slot card with a 225 W TDP, a single 16-pin power connector, and a suggested 550 W power supply. The 680M uses a PCIe 4.0 x8 interface and its display outputs are portable device dependent. The LX ULTRA uses PCIe 4.0 x16 and provides 4x DisplayPort 1.4a outputs.

Specification Differences

The two parts differ across nearly every recorded specification. Shading units: the Radeon 680M has 768, while the LX ULTRA has 6,144, exactly eight times more. Texture mapping units: 48 versus 192. Raster output units: 32 versus 96. The LX ULTRA's raw throughput numbers are correspondingly higher: pixel rate of 192.0 GPixel/s versus 70.40 GPixel/s, texture rate of 384.0 GTexel/s versus 105.6 GTexel/s, and FP32 compute of 24.58 TFLOPS versus 3.379 TFLOPS. FP16 rates follow the same pattern: 49.15 TFLOPS versus 6.758 TFLOPS, both at a 2:1 ratio.

Memory is the clearest differentiator. The 680M uses system shared memory with no dedicated VRAM, no fixed bus width, and bandwidth that depends on the host system. The LX ULTRA has 24 GB of GDDR6, a 192 bit bus, and 432.0 GB/s of bandwidth. Power draw also diverges sharply: 50 W for the 680M versus 225 W for the LX ULTRA. The physical form factor differs, with the 680M being an IGP and the LX ULTRA a dual-slot card measuring 268 mm in length, 112 mm in height, and 40 mm in width.

Release dates separate the parts by roughly three years. The Radeon 680M launched on January 2, 2023, while the LX ULTRA is dated March 16, 2026. The 680M has a predecessor (Vega II IGP) and a successor (Navi III IGP), while the LX ULTRA has neither. Both parts are listed as Active in production status.

Where Each One Wins

The AMD Radeon 680M wins in every category where empirical data exists. It has a verified average benchmark score of 15,270, a 57th percentile placement, and documented results in three separate tests. It also wins on power efficiency, with a 50 W TDP compared to the LX ULTRA's 225 W, and on physical footprint, as an IGP requires no expansion slot or power connectors. The 680M also holds an advantage in Vulkan API support, offering version 1.4 versus the LX ULTRA's 1.3.

The Lisuan Tech LX ULTRA wins on raw specification counts. It has 6,144 shading units versus 768, 192 TMUs versus 48, and 96 ROPs versus 32. Its FP32 throughput of 24.58 TFLOPS dwarfs the 680M's 3.379 TFLOPS. Its 24 GB of dedicated GDDR6 memory with 432.0 GB/s bandwidth is categorically different from the 680M's system shared memory. Its pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s are both substantially higher than the 680M's 70.40 GPixel/s and 105.6 GTexel/s. It also has a wider PCIe interface (x16 versus x8) and dedicated display outputs (4x DisplayPort 1.4a versus portable device dependent).

The distinction between the two parts is one of verification versus specification. The 680M has proven scores against named rivals, including a 0.1% delta from the GeForce GTX 580 and RTX 2060. The LX ULTRA has no scores at all. For workloads where measured performance matters, the 680M wins by default. For theoretical throughput and memory capacity, the LX ULTRA's specifications suggest it would dominate, but the database cannot confirm that suggestion. The LX ULTRA's 24.58 TFLOPS FP32 figure and 432.0 GB/s bandwidth are recorded specifications, not measured outcomes.

The production status of both parts is Active, but the LX ULTRA's release date of March 2026 places it as a newer design. The 680M, released in January 2023, has a known predecessor and successor, giving it a defined position in a product lineage. The LX ULTRA has no predecessor or successor recorded. In terms of connectivity, the LX ULTRA's 4x DisplayPort 1.4a outputs make it suitable for multi-monitor setups, while the 680M's display outputs depend entirely on the portable device it is integrated into.

The 680M's 12 ray tracing cores provide a hardware feature the LX ULTRA does not list, though no ray tracing benchmarks exist for either part. The 680M also has a lower power requirement by 175 W, which matters for systems with constrained power delivery. The LX ULTRA requires a 16-pin power connector and a suggested 550 W power supply, while the 680M needs none. Each part wins in its own domain: the 680M in verified efficiency and compatibility, the LX ULTRA in unverified peak specifications.
