AMD Radeon RX 7800M vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Radeon RX 7800M and the Lisuan Tech LX ULTRA. The headToHeadBenchmarks array is empty, and neither part has a shared test result to compare. The AMD Radeon RX 7800M has ten individual benchmark scores across DirectX, Vulkan, and compute workloads, while the Lisuan Tech LX ULTRA has no recorded benchmark scores at all.

The AMD Radeon RX 7800M delivers its strongest result in Geekbench Vulkan with a score of 126668, followed closely by Geekbench OpenCL at 120778. Its Passmark G3D score reaches 17613, with GPU compute at 9342. The average benchmark score across all recorded tests for the RX 7800M is 27883, placing it at the 73rd percentile among all GPUs in the database. The Lisuan Tech LX ULTRA holds a 50th percentile rating with an average benchmark score of 0, indicating no validated performance measurements exist for it in the current dataset.

The nearest rivals for the RX 7800M help contextualize its standing. The AMD Radeon Pro Vega 20 averages 27839, a delta of 0.2 percent above the RX 7800M. The AMD Radeon Pro W5500X averages 27973, sitting 0.3 percent higher. The NVIDIA GeForce GTX 980 Ti averages 28020, 0.5 percent above, and the AMD FirePro S7150 averages 28117, 0.8 percent higher. These margins are narrow, all within one percentage point, which places the RX 7800M in a tightly clustered performance band rather than at the top or bottom of its peer group.

Without any measured scores for the LX ULTRA, no delta percentages can be computed between the two products. The data does not support a claim that either part outperforms the other in any specific workload. The RX 7800M has observable results across multiple API levels, including Passmark DirectX 9 at 174, DirectX 10 at 99, DirectX 11 at 176, and DirectX 12 at 89. The LX ULTRA has no corresponding entries. The absence of benchmark data for the LX ULTRA means every comparison below relies on architectural specifications rather than measured performance.

The Verdict

The data indicates that the AMD Radeon RX 7800M is the only one of the two with validated performance results. Its average benchmark score of 27883 and 73rd percentile ranking come from ten recorded tests. The Lisuan Tech LX ULTRA has an average benchmark score of 0 and sits at the 50th percentile, which in this database reflects the absence of recorded measurements rather than an actual performance level.

For users who require verified performance data, the RX 7800M is the defensible choice. Its benchmark scores span DirectX 9 through 12, Vulkan, OpenCL, and 2D workloads, giving a broad picture of capability. The LX ULTRA offers no such evidence in the database, so any performance assessment would be speculative.

The RX 7800M also carries a lower thermal design power at 180 W compared to the LX ULTRA at 225 W. It is an integrated graphics package with no power connectors and an IGP slot width, while the LX ULTRA is a dual-slot card requiring one 16-pin connector and a 550 W suggested power supply. The LX ULTRA does have a larger memory pool at 24 GB versus 12 GB, which could matter for capacity-sensitive workloads, but no benchmark confirms whether that capacity translates into measured advantages.

The verdict from the recorded data is straightforward: the RX 7800M is the only part with demonstrated performance, while the LX ULTRA remains unverified. The choice between them depends entirely on whether a user trusts architectural specifications without benchmark confirmation.

Architecture Differences

The two GPUs diverge sharply in their underlying designs. The AMD Radeon RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas, and belongs to the Navi Mobile generation from the Radeon RX 7000 series. It is fabricated on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The Lisuan Tech LX ULTRA uses a 7G105 chip on a TrueGPU architecture from the 7G100 generation, built on a 6 nm process at TSMC. Its transistor count and die size are listed as unknown, so no density figure exists.

The RX 7800M has 3840 shading units, 240 texture mapping units, and 96 render output units. It includes 60 ray tracing cores. The LX ULTRA has 6144 shading units, 192 texture mapping units, and 96 render output units. It has no recorded ray tracing core count. The LX ULTRA carries more shading units by a wide margin, but fewer texture units, which changes the balance of work each chip can perform per clock.

Clock behavior differs substantially. 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 ULTRA has no base, boost, or game clock listed in the database. Both parts share the same memory clock at 2250 MHz with 18 Gbps effective transfer.

Memory configurations are similar in bus width and bandwidth but differ in capacity. Both use GDDR6 memory on a 192 bit bus with 432.0 GB/s bandwidth. The RX 7800M has 12 GB, while the LX ULTRA has 24 GB. The doubling of capacity does not change the raw bandwidth, so the LX ULTRA can hold more data but moves it at the same rate.

Compute throughput favors the RX 7800M in single precision. The RX 7800M delivers 35.87 TFLOPS FP32, while the LX ULTRA delivers 24.58 TFLOPS FP32. The LX ULTRA does have a higher FP16 figure at 49.15 TFLOPS with a 2:1 ratio, whereas the RX 7800M matches its FP32 at 35.87 TFLOPS with a 1:1 ratio. Pixel and texture rates also favor the RX 7800M: 224.2 GPixel/s and 560.4 GTexel/s versus 192.0 GPixel/s and 384.0 GTexel/s for the LX ULTRA.

Power and physical design diverge. The RX 7800M is listed at 180 W TDP, uses an IGP slot width, has no power connectors, and its display outputs are portable-device dependent. The LX ULTRA is rated at 225 W TDP, is a dual-slot card measuring 268 mm in length, 112 mm in height, and 40 mm in width, requires one 16-pin power connector, and offers four DisplayPort 1.4a outputs. The LX ULTRA also carries a 550 W suggested power supply, while the RX 7800M has no suggested PSU listed.

API support is close but not identical. Both support DirectX 12 Ultimate at feature level 12_2 and OpenGL 4.6. The RX 7800M supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RX 7800M uses a PCIe 4.0 x16 interface, and so does the LX ULTRA.

Where Each One Wins

The AMD Radeon RX 7800M wins in every category where measured data exists. Its ten recorded benchmark scores cover multiple DirectX versions, two Geekbench compute interfaces, and Passmark 2D and 3D tests. The highest individual score is 126668 in Geekbench Vulkan, with Geekbench OpenCL close behind at 120778. Its Passmark G3D score of 17613 and GPU compute score of 9342 provide additional confirmation of general compute capability. It also holds advantages in FP32 throughput at 35.87 TFLOPS, texture rate at 560.4 GTexel/s, and pixel rate at 224.2 GPixel/s. The RX 7800M is the only part with a percentile ranking based on actual results, sitting at the 73rd percentile.

The Lisuan Tech LX ULTRA wins in areas where its specifications exceed the RX 7800M. It has double the memory capacity at 24 GB versus 12 GB, which is the single largest specification advantage in the comparison. It also has more shading units at 6144 versus 3840, and a higher FP16 compute figure at 49.15 TFLOPS versus 35.87 TFLOPS. Its physical design includes four DisplayPort 1.4a outputs, while the RX 7800M's display outputs depend on the portable device it is integrated into. The LX ULTRA is a standalone dual-slot card with its own power connector, whereas the RX 7800M is an integrated graphics package.

For use cases that depend on measured performance, the RX 7800M is the only part with evidence in the database. For use cases that prioritize memory capacity or raw shading unit count, the LX ULTRA has the specification advantage, but no benchmark data confirms how those specifications translate into real workloads. The RX 7800M also uses a newer 5 nm process versus the LX ULTRA's 6 nm process, and its transistor count is documented at 28,100 million, while the LX ULTRA's is unknown.

The RX 7800M is better suited for workloads that stress FP32 compute, texture throughput, and pixel fill, based on its recorded performance and specification deltas. The LX ULTRA is better suited for workloads that require large memory footprints or that leverage FP16 arithmetic, given its 24 GB capacity and 2:1 FP16 ratio. Neither part has a confirmed advantage in ray tracing, since the RX 7800M lists 60 ray tracing cores and the LX ULTRA lists none, but no ray tracing benchmark results exist for either. The data supports a clear split: measured performance belongs to the RX 7800M, while specification-driven capacity advantages belong to the LX ULTRA.
