Architecture Differences

The RX 7800M is built around the RDNA 3.0 architecture on a 5 nm TSMC node, with a die size of 346 mm² and 28,100 million transistors, yielding a transistor density of 81.2M per mm². The Lisuan Tech LX PRO uses the TrueGPU architecture on a 6 nm TSMC process, with unknown die size and transistor counts. The process node difference means the RX 7800M uses a denser manufacturing technology, but the LX PRO compensates in other areas.

The shading unit counts diverge sharply. The LX PRO carries 6144 shading units, while the RX 7800M carries 3840. However, the RX 7800M has 240 TMUs versus 192 on the LX PRO, and both have 96 ROPs. The RX 7800M includes 60 ray tracing cores; the LX PRO does not list any ray tracing hardware. The RX 7800M also has a higher pixel rate at 224.2 GPixel/s versus 192.0 GPixel/s and a higher texture rate at 560.4 GTexel/s versus 384.0 GTexel/s.

Clock behavior differs as well. The RX 7800M has specified base, boost, and game clocks at 1295 MHz, 2335 MHz, and 2145 MHz respectively, while the LX PRO lists no base, boost, or game clocks. Both operate their GDDR6 memory at 2250 MHz with 18 Gbps effective speed, producing identical 432.0 GB/s bandwidth over a 192-bit bus. FP16 compute is handled differently: the RX 7800M achieves 35.87 TFLOPS at a 1:1 ratio with FP32, while the LX PRO reaches 49.15 TFLOPS at a 2:1 ratio, indicating the LX PRO's shader array is not as efficient for FP32 work.

The LX PRO is a discrete dual-slot card with a 248 mm length, 118 mm height, 48 mm width, a single 16-pin power connector, a 225 W TDP, and a 550 W suggested PSU. The RX 7800M is an IGP with no power connectors and a 180 W TDP, designed for portable-device integration. Display outputs also differ: the RX 7800M is portable-device dependent, while the LX PRO provides 4x DisplayPort 1.4a.

Head-to-Head Benchmarks

The database contains head-to-head benchmark results for the RX 7800M, while the LX PRO has no recorded benchmark scores. The RX 7800M's average benchmark score is 27883, placing it in the 73rd percentile among all GPUs. Its nearest rivals in the database are the AMD Radeon Pro Vega 20 with an average score of 27839 and a delta of 0.2%, the AMD Radeon Pro W5500X with 27973 and -0.3%, the NVIDIA GeForce GTX 980 Ti with 28020 and -0.5%, and the AMD FirePro S7150 with 28117 and -0.8%. These deltas show the RX 7800M is effectively level with its closest competition, with differences under one percentage point in either direction.

In specific tests, the RX 7800M scores 2994 in 3DMark Steel Nomad DX12, 120778 in Geekbench OpenCL, and 126668 in Geekbench Vulkan. Passmark results include 17613 in G3D, 9342 in GPU compute, 892 in G2D, 176 in DirectX 11, 174 in DirectX 9, 99 in DirectX 10, and 89 in DirectX 12. The LX PRO has no entries in any of these tests, so no direct numerical comparison can be drawn from the recorded data.

The absence of LX PRO benchmark data means the comparison relies on architectural and specification differences. The RX 7800M's FP32 throughput of 35.87 TFLOPS is 46% higher than the LX PRO's 24.58 TFLOPS, which is the single largest performance indicator in favor of the RX 7800M. The LX PRO counters with 49.15 TFLOPS FP16, but that advantage only applies to workloads using half-precision arithmetic.

Specification Differences

The two GPUs differ in nearly every major category. The RX 7800M uses a 5 nm process with 28,100 million transistors and a 346 mm² die, while the LX PRO uses a 6 nm process with unknown transistor and die figures. The RX 7800M belongs to the Radeon RX 7000 series with the Navi 32 chip, RDNA 3.0 architecture, and the codename Wheat Nas. The LX PRO uses the 7G105 chip, TrueGPU architecture, and the generation designation 7G100.

Memory capacity differs substantially: 12 GB for the RX 7800M versus 24 GB for the LX PRO, both GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. Shading units favor the LX PRO at 6144 versus 3840, but TMUs favor the RX 7800M at 240 versus 192. ROPs are equal at 96. Ray tracing cores exist only on the RX 7800M with 60 units. Pixel rate is 224.2 GPixel/s for the RX 7800M versus 192.0 GPixel/s for the LX PRO. Texture rate is 560.4 GTexel/s versus 384.0 GTexel/s. FP32 is 35.87 TFLOPS versus 24.58 TFLOPS. FP16 is 35.87 TFLOPS at 1:1 for the RX 7800M versus 49.15 TFLOPS at 2:1 for the LX PRO.

TDP is 180 W for the RX 7800M versus 225 W for the LX PRO. The RX 7800M is an IGP with no power connectors, while the LX PRO is dual-slot with a single 16-pin connector and a 550 W suggested PSU. The LX PRO has physical dimensions of 248 mm by 118 mm by 48 mm; the RX 7800M has no listed dimensions. Bus interface is PCIe 4.0 x16 for both. Display outputs are portable-device dependent for the RX 7800M versus 4x DisplayPort 1.4a for the LX PRO. Vulkan support is 1.4 for the RX 7800M versus 1.3 for the LX PRO; DirectX and OpenGL support are identical at 12 Ultimate (12_2) and 4.6.

Release dates also differ, with the RX 7800M released on 2024-09-10 and the LX PRO on 2026-03-16. The RX 7800M has a predecessor listed as Polaris Mobile; the LX PRO has no predecessor. Neither has a successor.

The Verdict

The RX 7800M is the only one of the two with recorded benchmark data, and that data places it in the 73rd percentile of all GPUs with an average score of 27883. The LX PRO sits at the 50th percentile with an average score of 0, indicating no measured performance in the database. Users seeking verified performance should choose the RX 7800M, as every performance figure in the database comes from that GPU.

The RX 7800M also delivers substantially higher FP32 compute at 35.87 TFLOPS, higher pixel and texture rates, and includes 60 ray tracing cores. The LX PRO cannot match these figures on paper, despite having more shading units. The LX PRO's advantages are limited to memory capacity at 24 GB and FP16 throughput at 49.15 TFLOPS, neither of which compensates for the complete lack of benchmark evidence.

Power draw is lower on the RX 7800M at 180 W versus 225 W, and it requires no external power connector, making it suitable for integrated portable systems. The LX PRO requires a 16-pin connector and a 550 W PSU, confining it to desktop builds. The RX 7800M also supports a newer Vulkan version at 1.4 versus 1.3.

Where Each One Wins

The RX 7800M wins in all measured performance categories because the LX PRO has no recorded scores. In raw compute, the RX 7800M leads with 35.87 TFLOPS FP32, a 46% advantage over the LX PRO's 24.58 TFLOPS. It also leads in pixel rate at 224.2 GPixel/s versus 192.0 GPixel/s and texture rate at 560.4 GTexel/s versus 384.0 GTexel/s. The 60 ray tracing cores on the RX 7800M give it a feature advantage for ray-traced workloads, as the LX PRO lists none.

The LX PRO wins in memory capacity with 24 GB versus 12 GB, which suits workloads requiring large frame buffers or data sets. It also wins in shading unit count at 6144 versus 3840 and in FP16 compute at 49.15 TFLOPS versus 35.87 TFLOPS, which matters for half-precision compute tasks. Its dual-slot design with 4x DisplayPort 1.4a outputs makes it a desktop-oriented card with explicit multi-monitor support, while the RX 7800M relies on portable-device-dependent outputs.

For integrated and low-power systems, the RX 7800M is the appropriate choice due to its 180 W TDP and lack of power connectors. For desktop builds with a 550 W PSU and a need for 24 GB of memory, the LX PRO is the only option that matches those requirements in this comparison. The RX 7800M is the better choice for verified performance, while the LX PRO is the better choice for capacity and half-precision throughput.
