AMD Radeon PRO W7900D vs Lisuan Tech LX 7G100 Comparison

Where Each One Wins

The recorded data shows no benchmark wins for either card in the head-to-head comparison, as both the AMD Radeon PRO W7900D and the Lisuan Tech LX 7G100 have zero wins in the database. The average benchmark score for both is 0, and each sits at the 50th percentile against all GPUs. This means the database has no measured performance deltas between these two cards, so any division of wins must be inferred from their architectural and specification differences rather than from direct empirical results.

The AMD Radeon PRO W7900D delivers 52.99 TFLOPS FP32 performance, which is more than double the 24.58 TFLOPS of the Lisuan Tech LX 7G100. That gap alone positions the AMD card as the stronger compute-oriented part for FP32 workloads. The W7900D also has 48 GB of GDDR6 memory on a 384-bit bus, yielding 864.0 GB/s of bandwidth, compared to 12 GB on a 192-bit bus for the LX 7G100 with 432.0 GB/s. The AMD card has 384 TMUs and 192 ROPs, while the Lisuan part has 192 TMUs and 96 ROPs, so texture-heavy and pixel-heavy workloads should favor the W7900D by a wide margin.

The Lisuan Tech LX 7G100 counters with a higher FP16 throughput of 49.15 TFLOPS at a 2:1 ratio, compared to the AMD card's 52.99 TFLOPS at a 1:1 ratio. The Lisuan part also draws less power, with a 225 W TDP versus 295 W, and uses a dual-slot cooler with a single 8-pin power connector, whereas the W7900D requires a triple-slot cooler and two 8-pin connectors. For dense FP16 compute where the 2:1 ratio is acceptable, the LX 7G100 delivers nearly the same raw throughput as the AMD card while consuming less power and occupying less slot space.

Architecture Differences

The AMD Radeon PRO W7900D uses the Navi 31 chip built on RDNA 3.0 architecture, with the Plum Bonito codename, and belongs to the Radeon Pro Navi (Navi III Series) generation. The Lisuan Tech LX 7G100 uses the 7G106 chip with an architecture labeled TrueGPU, and belongs to the 7G100 generation. Both are fabricated by TSMC, but the AMD card uses a 5 nm process while the Lisuan part uses a 6 nm process. The AMD card packs 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm², while the Lisuan card's transistor count and die size are listed as unknown in the database.

Both cards have 6144 shading units, but the AMD card has 384 TMUs and 192 ROPs, while the Lisuan card has 192 TMUs and 96 ROPs, exactly half in each category. The AMD card includes 96 ray tracing cores, whereas the Lisuan card has no RT core count listed. Neither card has tensor cores listed. The AMD card's pixel rate is 414.0 GPixel/s and its texture rate is 827.9 GTexel/s, while the Lisuan card achieves 192.0 GPixel/s and 384.0 GTexel/s. The FP32 performance of the AMD card is 52.99 TFLOPS, and its FP16 performance is also 52.99 TFLOPS at a 1:1 ratio, meaning there is no FP32/FP16 performance split. The Lisuan card delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 at a 2:1 ratio, indicating its FP16 units are clocked or configured differently relative to FP32.

Memory clocks are identical at 2250 MHz with 18 Gbps effective for both cards, but memory size, bus width, and bandwidth all differ substantially as noted above. The AMD card supports DisplayPort 2.1 on three full-size ports and one mini-DisplayPort 2.1, while the Lisuan card has four DisplayPort 1.4a outputs. The AMD card supports Vulkan 1.4, while the Lisuan card supports Vulkan 1.3; both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Lisuan card was released on 2025-09-24, while the AMD card was released on 2025-09-24 as well, so both share the same release date. The AMD card lists the Radeon Pro Vega as its predecessor, while the Lisuan card has no predecessor listed.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Radeon PRO W7900D and the Lisuan Tech LX 7G100. There are no measured scores, no delta percentages, and no nearest rivals listed for either card. Both cards have an average benchmark score of 0 and a percentile ranking of 50 against all GPUs. Consequently, there are no exact numbers from direct comparisons to walk through.

However, the specification data enables a meaningful computed comparison. The AMD card's FP32 throughput of 52.99 TFLOPS is 115.5% higher than the Lisuan card's 24.58 TFLOPS. The AMD card's texture rate of 827.9 GTexel/s is 115.6% higher than the Lisuan card's 384.0 GTexel/s, and its pixel rate of 414.0 GPixel/s is 115.6% higher than the Lisuan card's 192.0 GPixel/s. Memory bandwidth favors the AMD card by exactly 100%: 864.0 GB/s versus 432.0 GB/s. The AMD card has 4 times the memory capacity at 48 GB versus 12 GB, and its 384-bit bus is double the Lisuan card's 192-bit bus.

In FP16 compute, the gap narrows considerably. The AMD card's 52.99 TFLOPS is only 7.8% higher than the Lisuan card's 49.15 TFLOPS. The Lisuan card's 2:1 FP16 ratio means it can reach nearly the same peak FP16 throughput as the AMD card despite having half the shading units effectively dedicated to FP32 work. The Lisuan card also has a lower TDP of 225 W versus 295 W, a 23.7% reduction in power draw, and it uses a single 8-pin connector instead of two, while suggesting a 550 W PSU versus 600 W.

The Verdict

The data indicates a clear performance hierarchy. The AMD Radeon PRO W7900D delivers roughly twice the FP32 throughput, texture rate, pixel rate, and memory bandwidth of the Lisuan Tech LX 7G100, while also offering four times the memory capacity and 96 ray tracing cores. For FP32-heavy workloads such as scientific simulation, rendering, or general compute, the W7900D is the definitive choice based on the recorded specifications.

The Lisuan Tech LX 7G100 is a more efficient part in specific contexts. Its FP16 throughput of 49.15 TFLOPS is close to the AMD card's 52.99 TFLOPS, and it does so at a 225 W TDP with a dual-slot cooler and a single 8-pin connector. The Lisuan card also supports four DisplayPort 1.4a outputs versus the AMD card's three full-size DisplayPort 2.1 ports plus one mini-DisplayPort. Users who prioritize FP16 compute density, lower power draw, or more display outputs may find the Lisuan card viable, but only if their workloads can tolerate the 2:1 FP16 ratio and the substantially lower FP32 performance.

The AMD card's higher transistor count of 57,700 million on a 529 mm² die and a 5 nm process node indicate a more complex and capable silicon, while the Lisuan card's 6 nm process and unknown transistor count suggest a simpler design. The AMD card also supports Vulkan 1.4 and DisplayPort 2.1, both newer standards than the Lisuan card's Vulkan 1.3 and DisplayPort 1.4a. For general-purpose GPU compute, the AMD Radeon PRO W7900D is the stronger part in every measured dimension except FP16 ratio and power efficiency. The Lisuan Tech LX 7G100 occupies a niche for FP16-focused workloads where its lower power envelope and smaller physical footprint provide an advantage.
