AMD Radeon PRO W7400 vs Lisuan Tech LX 7G100 Comparison

The Verdict

The recorded data presents two fundamentally different devices sharing the same 6 nm TSMC process node but little else in common. The AMD Radeon PRO W7400 is a low-power, compact professional card built on RDNA 3.0 with a 55 W TDP, while the Lisuan Tech LX 7G100 is a large dual-slot accelerator with a 225 W TDP, a distinct TrueGPU architecture, and substantially higher raw compute specifications. Both cards sit at the 50th percentile versus all GPUs in the database, and neither has recorded benchmark scores, so the comparison relies entirely on architectural and specification-level differences.

For workloads that depend on raw floating-point throughput, memory bandwidth, pixel fill, and texture fill, the LX 7G100 dominates on paper. Its FP32 output of 24.58 TFLOPS is more than three times the W7400's 7.885 TFLOPS. Its FP16 output of 49.15 TFLOPS (2:1 ratio) is more than six times the W7400's 7.885 TFLOPS (1:1 ratio). The LX 7G100 also provides 432.0 GB/s of memory bandwidth versus 172.8 GB/s, 12 GB of memory versus 8 GB, and a 192-bit bus versus 128-bit. For compute-heavy tasks, the Lisuan part is the clear choice.

For environments with strict power, space, and cooling constraints, the W7400 offers a different profile. Its 55 W TDP requires no power connectors, fits in a single slot at 168 mm length, and needs only a 250 W suggested PSU. The LX 7G100 demands 225 W, an 8-pin connector, a dual-slot footprint, 294 mm length, and a 550 W suggested PSU. The W7400 also supports DisplayPort 2.1 outputs, whereas the LX 7G100 provides DisplayPort 1.4a. Users prioritizing low-power deployment, compact chassis compatibility, or newer display output standards would select the W7400.

Architecture Differences

The two cards come from different architectural lineages. The AMD Radeon PRO W7400 uses the Navi 33 chip with RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Radeon Pro Navi (Navi III Series) generation. The Lisuan Tech LX 7G100 uses the 7G106 chip with a TrueGPU architecture and belongs to the 7G100 generation. Both are fabricated on a 6 nm process at TSMC, but the similarities end there.

The W7400 packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per mm². The LX 7G100's transistor count and die size are not recorded in the database. The W7400 includes 1792 shading units, 112 texture mapping units, 64 render output units, and 28 ray tracing cores. The LX 7G100 provides 6144 shading units, 192 TMUs, and 96 ROPs, but its ray tracing core count is not listed. The Lisuan part has no tensor core data recorded, and neither card lists tensor cores.

Clock behavior differs significantly. The W7400 has a base clock of 330 MHz and a boost clock of 1100 MHz. The LX 7G100 has no base or boost clock recorded. Memory clocks also diverge: the W7400 runs at 1350 MHz with 10.8 Gbps effective, while the LX 7G100 runs at 2250 MHz with 18 Gbps effective. The W7400 uses an 8 GB GDDR6 pool on a 128-bit bus, while the LX 7G100 uses 12 GB GDDR6 on a 192-bit bus.

Power delivery and physical design reflect their different roles. The W7400 is a single-slot card with no power connectors, a 55 W TDP, and a suggested PSU of 250 W. The LX 7G100 is a dual-slot card with a single 8-pin connector, a 225 W TDP, and a suggested PSU of 550 W. Dimensions reinforce the contrast: the W7400 measures 168 mm by 69 mm by 20 mm, while the LX 7G100 measures 294 mm by 120 mm by 49 mm.

Bus interfaces also differ. The W7400 uses PCIe 4.0 x8, while the LX 7G100 uses PCIe 4.0 x16, giving the Lisuan part twice the interface width. Display outputs show a generation gap: the W7400 has four DisplayPort 2.1 outputs, while the LX 7G100 has four DisplayPort 1.4a outputs. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The W7400 supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark runs for these two cards, and neither has an average benchmark score. The comparison therefore rests on the specification-level metrics provided. Even without runtime scores, the recorded figures establish clear margins in several categories.

FP32 throughput favors the LX 7G100 by a factor of 3.12, at 24.58 TFLOPS versus 7.885 TFLOPS. FP16 throughput favors the Lisuan part even more strongly: 49.15 TFLOPS versus 7.885 TFLOPS, a 6.23x advantage. The W7400's FP16 runs at a 1:1 ratio with FP32, meaning it gains nothing from reduced precision, while the LX 7G100's 2:1 ratio doubles its FP16 output.

Memory bandwidth heavily favors the LX 7G100 at 432.0 GB/s versus 172.8 GB/s, a 2.5x margin. The 12 GB memory capacity exceeds the W7400's 8 GB by 50 percent. Pixel fill rate favors the LX 7G100 at 192.0 GPixel/s versus 70.40 GPixel/s, a 2.73x advantage. Texture fill rate favors the LX 7G100 at 384.0 GTexel/s versus 123.2 GTexel/s, a 3.12x margin.

The W7400's advantages are concentrated in power efficiency and physical footprint. Its 55 W TDP is 24.4 percent of the LX 7G100's 225 W TDP. The W7400 requires no power connector and a 250 W suggested PSU, while the LX 7G100 requires an 8-pin connector and a 550 W suggested PSU. The W7400's single-slot design at 168 mm length is substantially smaller than the dual-slot 294 mm LX 7G100. The W7400's DisplayPort 2.1 outputs are a newer standard than the LX 7G100's DisplayPort 1.4a.

The W7400 also draws from a longer product history. Its predecessor is the Radeon Pro Vega, and its release date is recorded as 2025-08-02. The LX 7G100 has no predecessor recorded and a release date of 2026-06-17. Neither card lists a successor, and neither has a launch MSRP in the database. Both are marked as Active in production status.

Where Each One Wins

The LX 7G100 wins every compute and memory category recorded in the database. Its FP32 throughput of 24.58 TFLOPS positions it for heavy floating-point workloads, and its FP16 output of 49.15 TFLOPS at a 2:1 ratio gives it a substantial advantage in mixed-precision tasks. The 432.0 GB/s memory bandwidth and 192-bit bus support data-heavy workloads, while 12 GB of GDDR6 provides more capacity for large working sets. The pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s indicate strong fill-bound performance. The PCIe 4.0 x16 interface doubles the host link width of the W7400's PCIe 4.0 x8, reducing transfer bottlenecks.

The W7400 wins in deployment flexibility. Its 55 W TDP permits operation without any power connectors, a configuration suited to systems where power delivery is limited. The 250 W suggested PSU is less than half the LX 7G100's 550 W requirement. The single-slot design and compact 168 mm length fit in chassis that cannot accommodate a 294 mm dual-slot card. The lack of a power connector simplifies installation in pre-built systems. The DisplayPort 2.1 outputs support a newer display standard than the LX 7G100's DisplayPort 1.4a, which matters for setups using recent monitors.

The W7400 also carries the RDNA 3.0 architecture with 28 ray tracing cores, a feature set absent from the LX 7G100's recorded specifications. The LX 7G100's TrueGPU architecture does not list ray tracing cores or tensor cores in the database. For applications using ray-traced rendering, the W7400's 28 RT cores provide a hardware path that the Lisuan part cannot claim from the recorded data.

The release timeline favors the W7400 in terms of market presence, with a 2025-08-02 release date versus the LX 7G100's 2026-06-17 date. The W7400 also has a recorded predecessor, the Radeon Pro Vega, indicating an established product lineage, while the LX 7G100 has no predecessor listed.

The two cards target different deployment profiles. The LX 7G100's specifications point toward compute-oriented systems with ample power, cooling, and physical space, where its 3.12x FP32 advantage, 2.5x bandwidth advantage, and larger memory pool can be fully utilized. The W7400's specifications point toward compact workstations and constrained environments, where its 55 W draw, single-slot footprint, and newer DisplayPort standard take priority over peak throughput. Neither card has recorded benchmark scores or nearest rivals in the database, so these conclusions derive entirely from the specification-level measurements available.
