AMD Radeon RX 7800 XT vs Lisuan Tech LX ULTRA Comparison

The Verdict

The data presents a clear split between two very different products. The AMD Radeon RX 7800 XT is a fully benchmarked, actively produced mainstream graphics card with a substantial body of recorded performance data. The Lisuan Tech LX ULTRA, by contrast, is an active product with a complete specification sheet but zero recorded benchmarks, zero average score, and no rival comparisons in the database. For any user who requires verified performance metrics, the RX 7800 XT is the only option with measurable data. The LX ULTRA offers a larger memory pool of 24 GB versus 16 GB, a higher shading unit count of 6144 versus 3840, and a lower power draw of 225 W versus 263 W, but none of those specifications have been validated by any benchmark result. The recorded data shows the RX 7800 XT holds the 51st percentile among all GPUs, with an average benchmark score of 11627, while the LX ULTRA sits at the 50th percentile with an average score of zero due to the absence of tests.

Architecture Differences

The AMD Radeon RX 7800 XT uses the Navi 32 chip built on the RDNA 3.0 architecture, with the codename Wheat Nas, and belongs to the Navi III (RX 7000) generation. It is fabricated by TSMC on a 5 nm process with 28,100 million transistors on a 346 mm² die, resulting in a transistor density of 81.2 million per square millimeter. The Lisuan Tech LX ULTRA uses the 7G105 chip based on the TrueGPU architecture, belongs to the 7G100 generation, and is also fabricated by TSMC but on a 6 nm process. The database records the LX ULTRA transistor count and die size as unknown, and it has no transistor density value.

The RX 7800 XT integrates 60 ray tracing cores, while the LX ULTRA has no recorded RT core count. The RX 7800 XT also has a 1:1 FP16 to FP32 ratio, delivering 37.32 TFLOPS for both precision formats. The LX ULTRA instead provides a 2:1 FP16 ratio, with 49.15 TFLOPS of FP16 compute against 24.58 TFLOPS of FP32. This indicates the LX ULTRA is structured for workloads that favor half-precision throughput, whereas the RX 7800 XT maintains equal throughput across both formats.

The two cards differ in API support as well. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the RX 7800 XT supports Vulkan 1.4 while the LX ULTRA supports Vulkan 1.3. The RX 7800 XT also has a more recent display output configuration, with one HDMI 2.1a port and three DisplayPort 2.1 outputs, while the LX ULTRA uses four DisplayPort 1.4a outputs. The RX 7800 XT uses dual 8-pin power connectors, while the LX ULTRA uses a single 16-pin connector.

Specification Differences

The two cards diverge across nearly every major specification field. The RX 7800 XT operates at a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. The LX ULTRA has no recorded base, boost, or game clock values in the database. Memory clocks differ as well: the RX 7800 XT runs at 2438 MHz with 19.5 Gbps effective, while the LX ULTRA runs at 2250 MHz with 18 Gbps effective.

Memory configuration is a significant differentiator. The RX 7800 XT uses a 256 bit bus with 624.1 GB/s of bandwidth, while the LX ULTRA uses a 192 bit bus with 432.0 GB/s of bandwidth. The LX ULTRA counters with a larger 24 GB capacity versus 16 GB on the RX 7800 XT.

Compute unit counts also favor the LX ULTRA in raw quantity. The LX ULTRA has 6144 shading units and 192 texture mapping units, while the RX 7800 XT has 3840 shading units and 240 TMUs. Both cards have 96 raster operation pipelines. Despite fewer shading units, the RX 7800 XT achieves a higher pixel rate of 233.3 GPixel/s versus 192.0 GPixel/s, and a higher texture rate of 583.2 GTexel/s versus 384.0 GTexel/s.

Physical dimensions are comparable, with the RX 7800 XT measuring 267 mm in length, 111 mm in height, and 50 mm in width, while the LX ULTRA measures 268 mm in length, 112 mm in height, and 40 mm in width. Both are dual-slot cards. The RX 7800 XT has a launch MSRP of 499 USD; the LX ULTRA has no recorded launch MSRP.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Radeon RX 7800 XT and the Lisuan Tech LX ULTRA, and neither card has any recorded wins in direct comparison. Consequently, the only interpretable performance data comes from the RX 7800 XT's individual benchmark suite and its nearest rival comparisons.

The RX 7800 XT records a 3DMark Steel Nomad DX12 score of 4157, a Geekbench OpenCL score of 18290, and a Geekbench Vulkan score of 54228. In PassMark tests, it scores 121 in DirectX 10, 249 in DirectX 11, 93 in DirectX 12, 304 in DirectX 9, 1177 in G2D, 24176 in G3D, and 13473 in GPU compute. Its average benchmark score across all tests is 11627.

Relative to its nearest rivals, the RX 7800 XT sits within a narrow band. It is 0.5% behind the NVIDIA GeForce GTX 1660, which has an average score of 11680, and 1.8% behind the AMD Radeon RX 6500 XT, which has an average score of 11842. It is 0.9% ahead of the AMD Radeon Pro 5500M (average 11528) and 1.3% ahead of the NVIDIA Tesla K20c (average 11479). These deltas indicate the RX 7800 XT is clustered tightly with mid-range competitors in the database's aggregate scoring, despite its high-end feature set.

For the LX ULTRA, the absence of benchmark data means no performance interpretation is possible. The database lists a percentile of 50 for the LX ULTRA, but with an average score of zero and no benchmark entries, this percentile carries no supporting evidence.

Where Each One Wins

The AMD Radeon RX 7800 XT wins in every category where measured data exists. It delivers higher FP32 throughput at 37.32 TFLOPS, higher pixel rate at 233.3 GPixel/s, and higher texture rate at 583.2 GTexel/s. It has a wider memory bus at 256 bit, higher memory bandwidth at 624.1 GB/s, and higher effective memory speed at 19.5 Gbps. It supports Vulkan 1.4, includes 60 ray tracing cores, and offers a mix of HDMI 2.1a and DisplayPort 2.1 outputs. Its benchmark scores are recorded across ten separate tests, and its nearest rival comparisons show it within 1.8% of the AMD Radeon RX 6500 XT and 0.5% of the NVIDIA GeForce GTX 1660.

The Lisuan Tech LX ULTRA wins on specification quantity in several fields. It has 24 GB of memory versus 16 GB, 6144 shading units versus 3840, and 192 TMUs versus 240 (though the RX 7800 XT still achieves a higher texture rate). It draws less power at 225 W versus 263 W, requires a 550 W PSU instead of 600 W, and uses a single 16-pin connector rather than dual 8-pin. It also has a higher FP16 throughput of 49.15 TFLOPS, which may benefit workloads optimized for half-precision arithmetic. However, with zero benchmark results, these advantages remain theoretical. The RX 7800 XT is the only card in this comparison with verified performance data, and it alone can be assessed for real-world behavior. The LX ULTRA is a specification sheet without measured validation, so any claim about its actual performance cannot be supported by the database.
