AMD Radeon PRO W7800 vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark comparisons between the AMD Radeon PRO W7800 and the Lisuan Tech LX PRO. The database lists no shared test results, no comparative scores, and no win counts for either product in a direct matchup. However, the available performance metrics for each card can be examined side by side to establish a performance hierarchy.

The AMD Radeon PRO W7800 delivers 45.25 TFLOPS of FP32 compute, while the Lisuan Tech LX PRO delivers 24.58 TFLOPS. This places the W7800 approximately 84% ahead in raw single-precision throughput. In FP16, the W7800 reaches 90.50 TFLOPS (2:1 ratio), while the LX PRO reaches 49.15 TFLOPS, a similar proportional gap of roughly 84%.

Texture fill rate follows the same pattern. The W7800 produces 707.0 GTexel/s, compared to 384.0 GTexel/s for the LX PRO, a difference of 84%. Pixel fill rate tells a similar story: the W7800 reaches 323.2 GPixel/s, while the LX PRO reaches 192.0 GPixel/s, putting the AMD card about 68% ahead.

Memory bandwidth also favors the W7800. It offers 576.0 GB/s across a 256-bit bus with 32 GB of GDDR6 memory. The LX PRO offers 432.0 GB/s across a 192-bit bus with 24 GB of GDDR6. The W7800 therefore holds a 33% bandwidth advantage and 8 GB more memory capacity.

The W7800 has 4480 shading units, 280 texture mapping units, and 128 render output units. The LX PRO has 6144 shading units, 192 TMUs, and 96 ROPs. Despite having 37% more shading units, the LX PRO trails in texture and pixel throughput because its lower clock rates and narrower backend limit realized performance. The W7800 also includes 70 dedicated ray tracing cores; the LX PRO lists no ray tracing core count.

In the only recorded benchmark scores, the W7800 achieves 154,366 in Geekbench OpenCL and 175,422 in Geekbench Vulkan. The LX PRO has no recorded benchmark scores in the database. The W7800 holds an average benchmark score of 164,894 and sits in the 97th percentile of all GPUs. The LX PRO sits in the 50th percentile with an average score of zero due to missing data.

Relative to its nearest rivals, the W7800 performs nearly identically to the NVIDIA RTX A5500, which has an average score of 165,217, a delta of negative 0.2%. It trails the RTX 4500 Ada Generation by 0.7% (166,094 average) and the AMD Radeon Pro W6900X by 2.2% (168,574 average). It leads the NVIDIA A100 PCIe 40 GB by 1.5% (162,504 average). These comparisons show the W7800 clustering tightly with professional workstation cards from the previous generation, neither dominating nor being dominated by those specific rivals.

The Verdict

The data indicates a clear performance hierarchy between these two cards, but the comparison is limited by the absence of direct benchmark results and the lack of any scores for the LX PRO.

The AMD Radeon PRO W7800 is the stronger card by every measured performance metric. It delivers higher FP32 compute, higher FP16 compute, higher texture rate, higher pixel rate, more memory, and more bandwidth. Its recorded Geekbench scores place it in the 97th percentile of all GPUs, and its average benchmark score of 164,894 shows it operating in the same class as the NVIDIA RTX A5500 and RTX 4500 Ada Generation. The LX PRO has no recorded scores, so its real-world positioning cannot be verified from the database.

The Lisuan Tech LX PRO does have one notable advantage: it uses a smaller process node. The LX PRO is built on a 6 nm TSMC process, while the W7800 uses a 5 nm TSMC process. The LX PRO also has more shading units (6144 versus 4480) and a lower TDP (225 W versus 260 W). However, none of these advantages translate into higher recorded performance. The LX PRO also lacks ray tracing core data, while the W7800 includes 70 RT cores.

For users prioritizing compute throughput, memory capacity, ray tracing hardware, and verified benchmark performance, the W7800 is the clear choice. For users prioritizing lower power draw and a more compact physical footprint, the LX PRO may hold some appeal, though its performance claims cannot be confirmed from the current data.

Architecture Differences

The two cards come from entirely different design lineages. The AMD Radeon PRO W7800 uses the Navi 31 chip built on the RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Radeon Pro Navi generation (Navi III Series). The chip is manufactured on a 5 nm process at TSMC and contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million transistors per square millimeter.

The Lisuan Tech LX PRO uses the 7G105 chip built on the TrueGPU architecture, belonging to the 7G100 generation. It is manufactured on a 6 nm process at TSMC. The database lists its transistor count and die size as unknown.

The W7800 includes 70 dedicated ray tracing cores, a feature absent from the LX PRO specification listing. The W7800 also supports a wider range of display outputs: 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, compared to 4x DisplayPort 1.4a on the LX PRO. The DisplayPort 2.1 standard on the W7800 supports higher bandwidth than DisplayPort 1.4a, which is relevant for high-resolution or high-refresh-rate displays.

API support differs slightly. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The W7800 supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3.

The W7800 uses two 8-pin power connectors and recommends a 600 W power supply. The LX PRO uses a single 16-pin connector and recommends a 550 W power supply. The W7800 has a TDP of 260 W; the LX PRO has a TDP of 225 W. Both cards are dual-slot designs.

The W7800 measures 280 mm in length, 110 mm in height, and 40 mm in width. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width. The LX PRO is shorter but taller and thicker.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every category where measurable data exists. Its FP32 compute is 84% higher than the LX PRO. Its FP16 compute is 84% higher. Its texture fill rate is 84% higher. Its pixel fill rate is 68% higher. Its memory bandwidth is 33% higher. Its memory capacity is 8 GB higher. It has 70 ray tracing cores, while the LX PRO lists none. It supports Vulkan 1.4 versus Vulkan 1.3 on the LX PRO. It uses DisplayPort 2.1 outputs versus DisplayPort 1.4a on the LX PRO. Its recorded Geekbench scores place it in the 97th percentile of all GPUs, and its average benchmark score of 164,894 puts it within 2.2% of the AMD Radeon Pro W6900X, a similarly positioned workstation card.

The Lisuan Tech LX PRO wins in a smaller set of categories. It has more shading units: 6144 versus 4480. It has a lower TDP: 225 W versus 260 W. It requires a smaller recommended power supply: 550 W versus 600 W. It uses a single 16-pin power connector instead of two 8-pin connectors. It is shorter in length: 248 mm versus 280 mm. It offers four DisplayPort outputs rather than three DisplayPort outputs plus one mini-DisplayPort. It is built on a 6 nm process, though the W7800 uses the smaller 5 nm node.

The LX PRO cannot claim a win in any recorded performance benchmark because no benchmark data exists for it. Its higher shading unit count does not translate into higher texture or pixel throughput in the specification sheet, suggesting that other factors, likely clock speeds, limit its realized output. The W7800, by contrast, shows consistent advantages across compute, memory, and output stages.
