AMD Radeon PRO W7800 vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two workstation GPUs. The AMD Radeon PRO W7800 has two benchmark entries in the database, while the Lisuan Tech LX ULTRA has no recorded benchmark scores at all. This absence of data for the LX ULTRA is itself a significant finding, as it places the card at the 50th percentile among all GPUs with an average benchmark score of 0. The Radeon PRO W7800, by comparison, sits at the 97th percentile with an average benchmark score of 164,894.

In Geekbench OpenCL, the Radeon PRO W7800 scores 154,366 points. In Geekbench Vulkan, it scores 175,422 points. These figures anchor its position in the upper tier of workstation graphics hardware. The nearest rival data confirms this placement: the NVIDIA RTX A5500 averages 165,217 points, which is 0.2% above the W7800. The NVIDIA RTX 4500 Ada Generation averages 166,094 points, 0.7% above. The AMD Radeon Pro W6900X averages 168,574 points, 2.2% above. Only the NVIDIA A100 PCIe 40 GB trails slightly, averaging 162,504 points, which is 1.5% below the W7800. These narrow margins indicate the W7800 operates in a tightly contested performance band, trading positions with several professional cards depending on the specific workload.

For the LX ULTRA, the database contains no scores to compare directly. Its percentile ranking of 50 with an average score of 0 reflects this absence rather than actual performance. The card's specifications suggest it targets a different market segment, but without benchmark data, any head-to-head numerical comparison remains impossible. The data simply does not support a direct score-by-score breakdown between these two products.

Where Each One Wins

The Radeon PRO W7800 wins on measured performance, memory capacity, memory bandwidth, and compute throughput. Its FP32 rate of 45.25 TFLOPS is roughly 84% higher than the LX ULTRA's 24.58 TFLOPS. Its FP16 rate of 90.50 TFLOPS (2:1) similarly outpaces the LX ULTRA's 49.15 TFLOPS (2:1). Texture rate favors the W7800 at 707.0 GTexel/s versus 384.0 GTexel/s, and pixel rate favors it at 323.2 GPixel/s versus 192.0 GPixel/s. The W7800 also offers 128 ROPs against 96 ROPs on the LX ULTRA, and 280 TMUs against 192 TMUs. Memory capacity and bandwidth both favor AMD's card, with 32 GB versus 24 GB and 576.0 GB/s versus 432.0 GB/s.

The LX ULTRA wins on shading unit count, with 6,144 units versus 4,480. It also has a lower TDP at 225 W versus 260 W, and a lower suggested power supply at 550 W versus 600 W. The LX ULTRA offers four DisplayPort 1.4a outputs, while the W7800 offers three DisplayPort 2.1 outputs plus one mini-DisplayPort 2.1. The LX ULTRA is slightly shorter at 268 mm versus 280 mm for the W7800. These advantages matter in specific deployment scenarios, particularly where power draw and physical footprint are constraints.

The absence of benchmark data for the LX ULTRA means its wins are purely specification-based. The measured performance wins belong entirely to the W7800. For applications that rely on rasterization throughput, memory bandwidth, or compute density, the data clearly favors the AMD card. For installations where power consumption and output port count take priority, the LX ULTRA presents a reasonable alternative on paper.

Specification Differences

The two cards differ across nearly every major specification category. The W7800 uses a 5 nm process node, while the LX ULTRA uses 6 nm. Both are fabricated by TSMC. The W7800 has 57,700 million transistors on a 529 mm² die, giving a transistor density of 109.1M per mm². The LX ULTRA's transistor count and die size are recorded as unknown, with no density figure available.

Clock behavior differs substantially. The W7800 has a base clock of 1895 MHz and a boost clock of 2525 MHz. The LX ULTRA has no base or boost clock listed. Both cards run memory at 2250 MHz with 18 Gbps effective speed.

Memory configuration shows the W7800 with 32 GB GDDR6 on a 256-bit bus, and the LX ULTRA with 24 GB GDDR6 on a 192-bit bus. Bandwidth follows accordingly at 576.0 GB/s versus 432.0 GB/s.

Compute units differ in composition. The W7800 has 4,480 shading units, 280 TMUs, 128 ROPs, and 70 ray tracing cores. The LX ULTRA has 6,144 shading units, 192 TMUs, 96 ROPs, and no ray tracing core count listed. Pixel rate for the W7800 is 323.2 GPixel/s versus 192.0 GPixel/s for the LX ULTRA. Texture rate is 707.0 GTexel/s versus 384.0 GTexel/s.

Power delivery differs as well. The W7800 draws up to 260 W TDP with 2x 8-pin connectors and a 600 W suggested PSU. The LX ULTRA draws 225 W TDP with a 1x 16-pin connector and a 550 W suggested PSU.

Display outputs are another point of divergence. The W7800 provides 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. The LX ULTRA provides 4x DisplayPort 1.4a.

Physical dimensions are close but not identical. The W7800 measures 280 mm by 110 mm by 40 mm. The LX ULTRA measures 268 mm by 112 mm by 40 mm. Both are dual-slot cards with PCIe 4.0 x16 interfaces.

Release dates place these products in different eras. The W7800 launched on April 12, 2023, while the LX ULTRA's release date is recorded as March 16, 2026. The W7800 has a launch MSRP of 2,499 USD; the LX ULTRA has no launch MSRP listed.

Architecture Differences

The Radeon PRO W7800 is built on the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito. It belongs to the Radeon Pro Navi generation, specifically the Navi III Series. Its predecessor is the Radeon Pro Vega. The card uses a chiplet-based design manufactured on a 5 nm TSMC process.

The Lisuan Tech LX ULTRA uses the TrueGPU architecture with the 7G105 chip and belongs to the 7G100 generation. Its manufacturer is listed as unknown, and no codename or predecessor is recorded. The process node is 6 nm, also from TSMC.

Ray tracing support differentiates the two. The W7800 specifies 70 ray tracing cores, while the LX ULTRA lists no ray tracing core count. This suggests the W7800 has dedicated hardware for ray-traced workloads, while the LX ULTRA's approach to ray tracing remains unspecified in the database.

Vulkan API support differs by one version. The W7800 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. DirectX and OpenGL support are identical at 12 Ultimate (12_2) and 4.6 respectively.

The transistor density figure for the W7800, at 109.1M per mm², reflects the denser 5 nm process. The LX ULTRA's process node is larger at 6 nm, but without transistor or die size data, density cannot be calculated for comparison.

The W7800's architecture carries a 70-core ray tracing array and a 2:1 FP16 ratio, indicating a design optimized for both traditional rasterization and emerging ray-tracing workloads. The LX ULTRA's TrueGPU architecture, despite having more shading units, lacks documented ray tracing hardware and shows lower throughput rates across pixel, texture, and FP32 metrics.

The Verdict

The data points to a clear conclusion for most professional workloads. The AMD Radeon PRO W7800 delivers measured benchmark scores at the 97th percentile among all GPUs, with an average score of 164,894. Its nearest rivals are all within a narrow 2.2% band, confirming its competitive position in the professional graphics market. The card offers 32 GB of memory, 576.0 GB/s of bandwidth, 45.25 TFLOPS of FP32 performance, and 70 ray tracing cores. These specifications support demanding compute, rendering, and ray-traced visualization tasks.

The Lisuan Tech LX ULTRA presents a more difficult case. Its 50th percentile ranking and average score of 0 reflect the complete absence of benchmark data. Its specifications show a card with 6,144 shading units, 24 GB of memory, 432.0 GB/s of bandwidth, and 24.58 TFLOPS of FP32 performance. These figures place it below the W7800 in most measurable throughput categories. The LX ULTRA does offer a lower TDP of 225 W, four DisplayPort 1.4a outputs, and a smaller footprint at 268 mm in length.

Users who need verified performance, validated by benchmark results and positioned against known competitors, should select the Radeon PRO W7800. The database shows it competing within 2.2% of cards like the NVIDIA RTX A5500, RTX 4500 Ada Generation, and AMD Radeon Pro W6900X. Users who prioritize lower power draw, more display outputs, or a shorter card length may consider the LX ULTRA, but they must accept that its performance has no recorded benchmark validation. The W7800 is the only card in this comparison with measurable, verifiable performance data.
