Architecture Differences

The AMD Radeon PRO W7900 is built on the RDNA 3.0 architecture using the Navi 31 chip, codenamed Plum Bonito, and belongs to the Radeon Pro Navi (Navi III Series) generation. It is fabricated on a 5 nm process at TSMC, with 57,700 million transistors packed into a 529 mm² die, yielding a transistor density of 109.1M per mm².

The Lisuan Tech LX 7G100 uses a fundamentally different architecture called TrueGPU, based on the 7G106 chip, with no codename listed. It is manufactured on a 6 nm process, also at TSMC, but its transistor count and die size are listed as unknown. The Lisuan card belongs to the 7G100 generation and has no predecessor or successor in the database.

Both cards share the same shading unit count at 6,144, but the AMD Radeon PRO W7900 doubles the TMUs with 384 versus 192, and doubles the ROPs with 192 versus 96. The AMD card also integrates 96 ray tracing cores, while the Lisuan card has no dedicated RT hardware listed. Neither card includes tensor cores.

The AMD Radeon PRO W7900 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Lisuan Tech LX 7G100 matches DirectX 12 Ultimate (12_2) and OpenGL 4.6, but supports Vulkan 1.3. The AMD card provides three DisplayPort 2.1 outputs plus one mini-DisplayPort 2.1, while the Lisuan card offers four DisplayPort 1.4a outputs. Both use a PCIe 4.0 x16 bus interface.

Physical dimensions differ as well. The AMD card measures 280 mm in length, 110 mm in height, and 51 mm in width, occupying a triple-slot form factor. The Lisuan card is slightly longer at 294 mm, taller at 120 mm, and narrower at 49 mm, using a dual-slot design.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark results recorded between the AMD Radeon PRO W7900 and the Lisuan Tech LX 7G100 in the database. The Lisuan card currently has zero recorded benchmarks, while the AMD card has two Geekbench entries. However, the specification data provides clear comparative performance indicators.

In FP32 compute, the AMD Radeon PRO W7900 delivers 61.32 TFLOPS, which is 2.5 times the 24.58 TFLOPS of the Lisuan Tech LX 7G100. This is the largest compute gap between the two cards, directly reflecting the higher shading unit count combined with the AMD card's higher clock capabilities.

The memory subsystem heavily favors the AMD card. With 48 GB on a 384-bit bus, the AMD Radeon PRO W7900 reaches 864.0 GB/s of bandwidth. The Lisuan Tech LX 7G100, with 12 GB on a 192-bit bus, achieves 432.0 GB/s. Both cards use GDDR6 memory at 2250 MHz (18 Gbps effective), so the bandwidth difference comes entirely from the wider bus and larger capacity.

Pixel throughput shows a similar pattern. The AMD card renders at 479.0 GPixel/s, while the Lisuan card manages 192.0 GPixel/s, a 2.5x advantage for AMD. Texture throughput follows with 958.1 GTexel/s for AMD versus 384.0 GTexel/s for Lisuan, again a 2.5x gap.

The FP16 results present an interesting nuance. The AMD Radeon PRO W7900 achieves 61.32 TFLOPS in FP16 with a 1:1 ratio to FP32. The Lisuan Tech LX 7G100 reaches 49.15 TFLOPS in FP16 using a 2:1 ratio, meaning its FP16 performance is twice its FP32 output. In absolute FP16 terms, AMD still leads by 1.25x, but the Lisuan card closes the gap more in FP16 workloads than in FP32.

The AMD Radeon PRO W7900 carries an average benchmark score of 110,725, placing it in the 94th percentile among all GPUs. Its nearest rivals in the database include the AMD Radeon Pro Vega II at 109,617 (1% lower), the NVIDIA RTX A5500 Mobile at 113,944 (2.8% higher), the AMD Radeon Pro W6600X at 107,342 (3.2% lower), and the NVIDIA Tesla V100 SXM2 16 GB at 114,395 (3.2% higher). The Lisuan Tech LX 7G100 has no rivals listed and sits at the 50th percentile with a zero average score.

The Verdict

The data clearly positions the AMD Radeon PRO W7900 as the substantially more capable workstation graphics card. Its 48 GB memory capacity, 864.0 GB/s bandwidth, 61.32 TFLOPS FP32 compute, and 96 ray tracing cores give it commanding leads across every measurable compute and rendering metric. The 94th percentile ranking among all GPUs, supported by concrete Geekbench scores of 84,379 in OpenCL and 137,070 in Vulkan, confirms its placement in the upper tier of available graphics hardware.

The Lisuan Tech LX 7G100, with 12 GB memory, 432.0 GB/s bandwidth, 24.58 TFLOPS FP32 compute, and no ray tracing cores, sits at the 50th percentile. Its lack of recorded benchmarks means the database contains no direct performance evidence for this card. The specifications suggest a mid-range offering with a lower 225 W TDP and single 8-pin power requirement, making it a more modest installation.

For workloads requiring large datasets, high-resolution rendering, ray tracing, or sustained FP32 compute, the AMD Radeon PRO W7900 is the clear choice based on the recorded data. The Lisuan Tech LX 7G100 may fit scenarios where FP16 throughput matters more relative to its FP32 capability, but with no benchmark verification and half the memory bandwidth, it cannot match the AMD card's overall performance envelope.

Shared specifications include 6,144 shading units, GDDR6 memory type, 2250 MHz memory clock (18 Gbps effective), PCIe 4.0 x16 interface, DirectX 12 Ultimate (12_2), OpenGL 4.6, TSMC foundry, and Active production status.

Where Each One Wins

The AMD Radeon PRO W7900 wins decisively in memory capacity and bandwidth. With 48 GB and 864.0 GB/s, it suits large-scale datasets, high-resolution textures, multi-display setups, and memory-intensive compute tasks. The 384-bit bus provides 2x the bandwidth of the Lisuan card, which matters for GPU-bound rendering and data processing workloads.

The AMD card also wins in FP32 compute, delivering 61.32 TFLOPS versus 24.58 TFLOPS. This positions it for scientific computing, simulation, and professional rendering where FP32 precision is the standard. Its 96 ray tracing cores add hardware acceleration for ray-traced workflows, a feature entirely absent from the Lisuan card.

The Lisuan Tech LX 7G100 shows a relative strength in FP16 efficiency. Its 2:1 FP16 ratio yields 49.15 TFLOPS, which is close to the AMD card's 61.32 TFLOPS FP16 output despite the Lisuan card having far lower FP32 performance. Workloads that can operate in reduced precision may see the Lisuan card perform closer to the AMD card than its FP32 numbers suggest.

The Lisuan card also wins on physical requirements. Its 225 W TDP, single 8-pin connector, 550 W suggested PSU, and dual-slot design make it easier to install in compact systems. The AMD card requires 295 W, two 8-pin connectors, a 600 W PSU, and a triple-slot footprint.

The Lisuan card offers four DisplayPort 1.4a outputs versus the AMD card's three DisplayPort 2.1 plus one mini-DisplayPort 2.1. For multi-monitor setups using standard DisplayPort connections only, the Lisuan card provides one additional full-size port, though the AMD card supports the newer DisplayPort 2.1 standard.

For Vulkan workloads, the AMD Radeon PRO W7900 supports Vulkan 1.4, ahead of the Lisuan card's Vulkan 1.3. The AMD card also has recorded benchmark validation with an average score of 110,725, while the Lisuan card has no performance data in the database.
