These deltas indicate that the AMD card operates within a tight competitive band, roughly 3% in either direction of its peers.

The Lisuan Tech LX ULTRA lacks benchmark entries, making it impossible to verify its standing against those same rivals. Its 50th percentile ranking suggests mid-pack placement relative to all GPUs, but without an average score or rival list, the database cannot substantiate any specific performance claim. The AMD card, by contrast, has a verified percentile ranking of 94, meaning it outperforms the vast majority of recorded GPUs in the database.

In terms of raw compute rates, the AMD Radeon PRO W7900 reaches 61.32 TFLOPS for FP32 and 61.32 TFLOPS for FP16 at a 1:1 ratio. The Lisuan Tech LX ULTRA reaches 24.58 TFLOPS for FP32 and 49.15 TFLOPS for FP16 at a 2:1 ratio. The AMD card delivers 2.5 times the FP32 throughput of the Lisuan card. For FP16, the AMD card delivers roughly 1.25 times the throughput. The Lisuan Tech LX ULTRA does show a higher FP16 to FP32 ratio, which indicates its architecture favors half-precision workloads, but its absolute FP16 number still falls below the AMD card's FP16 figure.

Pixel and texture throughput follow the same pattern. The AMD Radeon PRO W7900 records 479.0 GPixel/s and 958.1 GTexel/s. The Lisuan Tech LX ULTRA records 192.0 GPixel/s and 384.0 GTexel/s. The AMD card more than doubles the Lisuan card in both categories. Memory bandwidth also favors AMD: 864.0 GB/s versus 432.0 GB/s, exactly double. These figures point to a consistent advantage for the AMD card across fill-rate and bandwidth-limited tasks.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every performance category where the database holds comparable data. Its FP32 compute rate of 61.32 TFLOPS is more than double the 24.58 TFLOPS of the Lisuan Tech LX ULTRA, which gives it a clear advantage in general compute workloads, simulation, and tasks that rely on single-precision math. Its FP16 rate of 61.32 TFLOPS also exceeds the Lisuan card's 49.15 TFLOPS, so it remains ahead even in half-precision work, despite the Lisuan card's 2:1 FP16 ratio indicating a relative strength in that area.

The AMD card's memory subsystem is another decisive win. With 48 GB of GDDR6 and 864.0 GB/s of bandwidth, it holds twice the capacity and twice the bandwidth of the Lisuan Tech LX ULTRA's 24 GB and 432.0 GB/s. Large datasets, high-resolution textures, and workloads that exceed 24 GB of VRAM will only fit on the AMD card. The 384 bit bus versus 192 bit bus also contributes to the bandwidth gap.

Rasterization throughput favors AMD as well. The Radeon PRO W7900 records 479.0 GPixel/s and 958.1 GTexel/s, while the Lisuan card records 192.0 GPixel/s and 384.0 GTexel/s. These numbers suggest the AMD card can sustain higher fill rates in rendering scenarios that stress pixel and texture output.

The Lisuan Tech LX ULTRA wins in areas that are not directly performance related. It has a lower TDP of 225 W versus 295 W for the AMD card, and it fits in a dual-slot form factor compared to the AMD card's triple-slot design. It also uses a single 16-pin power connector rather than two 8-pin connectors, and its suggested PSU is 550 W versus 600 W. Its dimensions are smaller in length and width: 268 mm and 40 mm versus 280 mm and 51 mm, though it is slightly taller at 112 mm versus 110 mm. The Lisuan card also provides four DisplayPort 1.4a outputs compared to the AMD card's three DisplayPort 2.1 and one mini-DisplayPort 2.1.

Specification Differences

The two cards differ in nearly every recorded specification. The AMD Radeon PRO W7900 uses the Navi 31 chip with RDNA 3.0 architecture, while the Lisuan Tech LX ULTRA uses the 7G105 chip with TrueGPU architecture. The process nodes differ: 5 nm for AMD, 6 nm for Lisuan, both at TSMC. The AMD card lists 57,700 million transistors on a 529 mm² die with a transistor density of 109.1M per mm². The Lisuan card lists unknown transistor count, unknown die size, and no density figure.

Memory configurations diverge sharply. The AMD card has 48 GB of GDDR6 on a 384 bit bus with 864.0 GB/s bandwidth. The Lisuan card has 24 GB of GDDR6 on a 192 bit bus with 432.0 GB/s bandwidth. Both use the same memory clock of 2250 MHz at 18 Gbps effective.

Compute unit organization differs as well. Both cards list 6144 shading units, but the AMD card has 384 TMUs and 192 ROPs, while the Lisuan card has 192 TMUs and 96 ROPs. The AMD card lists 96 ray tracing cores; the Lisuan card lists no ray tracing cores. Neither card lists tensor cores.

Clock speeds are only recorded for the AMD card: 1760 MHz base and 2495 MHz boost. The Lisuan card has no base or boost clocks in the database. Power and physical specifications also differ. The AMD card has a 295 W TDP, triple-slot width, two 8-pin connectors, and a 600 W suggested PSU. The Lisuan card has a 225 W TDP, dual-slot width, one 16-pin connector, and a 550 W suggested PSU. Dimensions: AMD is 280 mm by 110 mm by 51 mm; Lisuan is 268 mm by 112 mm by 40 mm.

Display outputs differ: the AMD card has three DisplayPort 2.1 and one mini-DisplayPort 2.1; the Lisuan card has four DisplayPort 1.4a. API support is nearly identical, with both supporting DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the AMD card supports Vulkan 1.4 while the Lisuan card supports Vulkan 1.3. The AMD card launched in 2023 with a launch MSRP of 3,999 USD. The Lisuan card has a 2026 release date and no recorded launch MSRP.

Architecture Differences

The AMD Radeon PRO W7900 is built on RDNA 3.0, the architecture used across the Radeon Pro Navi generation. It uses the Navi 31 chip with the codename Plum Bonito. The Lisuan Tech LX ULTRA uses an architecture called TrueGPU, with the chip designated 7G105 and a generation label of 7G100. These represent fundamentally different design approaches, though the database records only limited architectural detail for the Lisuan card.

The manufacturing processes differ by one node step. AMD uses TSMC's 5 nm process, while Lisuan uses TSMC's 6 nm process. The AMD chip integrates 57,700 million transistors on a 529 mm² die, yielding a density of 109.1M transistors per mm². The Lisuan chip's transistor count and die size are unknown, so its density cannot be calculated.

Compute resource allocation differs significantly. Both cards have 6144 shading units, but the AMD card pairs them with 384 TMUs and 192 ROPs. The Lisuan card pairs its 6144 shading units with 192 TMUs and 96 ROPs. This means the AMD card has twice the texture units and twice the raster operation units. The AMD card also includes 96 ray tracing cores, while the Lisuan card does not list any.

FP16 execution differs in ratio. The AMD card runs FP16 at a 1:1 ratio with FP32, both at 61.32 TFLOPS. The Lisuan card runs FP16 at a 2:1 ratio, reaching 49.15 TFLOPS FP16 versus 24.58 TFLOPS FP32. This indicates the Lisuan architecture dedicates more hardware to half-precision math relative to its single-precision throughput, a design choice that can benefit AI-style workloads if software supports it. The AMD card's higher absolute FP16 output still gives it the edge in raw half-precision throughput.

The Lisuan card's pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s follow directly from its halved ROP and TMU counts. The AMD card's 479.0 GPixel/s and 958.1 GTexel/s reflect its doubled resources. The memory architecture also diverges: AMD uses a 384 bit bus, Lisuan uses a 192 bit bus, which halves the Lisuan card's memory bandwidth to 432.0 GB/s despite identical memory clock speeds.

The Verdict

The data in the database points to a straightforward conclusion for most use cases. The AMD Radeon PRO W7900 is the stronger card for compute-heavy and rendering-heavy workloads. It holds a 2.5x advantage in FP32 throughput, a 1.25x advantage in FP16 throughput, double the pixel rate, double the texture rate, double the memory capacity, and double the memory bandwidth. Its 94th percentile ranking among all GPUs and its verified average score of 110,725 place it in a competitive tier with the NVIDIA RTX A5500 Mobile and the NVIDIA Tesla V100 SXM2 16 GB, where it trails by only 2.8% and 3.2% respectively. It is also ahead of the AMD Radeon Pro Vega II by 1% and the AMD Radeon Pro W6600X by 3.2%.

The Lisuan Tech LX ULTRA cannot be validated against those rivals because it has no recorded benchmarks, no average score, and no nearest rival list. Its 50th percentile ranking indicates a mid-tier position, but the lack of measurement data means any specific performance claim would be unsupported. The card does show a clear architectural focus on FP16 throughput relative to FP32, and its 2:1 FP16 ratio is its only recorded performance distinction. It also wins on power efficiency in terms of TDP: 225 W versus 295 W, and it occupies less physical space with a dual-slot design and a 40 mm width.

For users selecting between these two based on the database, the AMD Radeon PRO W7900 is the only card with measured performance evidence. Its higher memory capacity alone, 48 GB versus 24 GB, makes it the only option for workloads that exceed 24 GB of VRAM. Its doubled bandwidth and fill rates support higher resolution rendering and larger texture sets. The Lisuan Tech LX ULTRA may be preferable in constrained chassis environments or where power draw is a limiting factor, given its lower TDP, dual-slot footprint, and single 16-pin connector, but the database contains no performance data to confirm its capabilities. The AMD card's launch MSRP is 3,999 USD, and its production status is active; the Lisuan card's production status is also active. Based on recorded data alone, the AMD Radeon PRO W7900 delivers verified performance across every measurable category, while the Lisuan Tech LX ULTRA remains an unmeasured entry in the database.
