AMD Radeon RX 7900 GRE vs Lisuan Tech LX ULTRA Comparison

AMD Radeon RX 7900 GRE vs Lisuan Tech LX ULTRA

The benchmark database contains no head-to-head test results for the AMD Radeon RX 7900 GRE and the Lisuan Tech LX ULTRA. The RX 7900 GRE has a full suite of recorded scores, while the LX ULTRA currently has no benchmark entries, an average benchmark score of zero, and no nearest rival data. The RX 7900 GRE sits at the 77th percentile among all GPUs in the database, whereas the LX ULTRA is listed at the 50th percentile, a position that reflects its absence of measured performance rather than a tested result. The analysis below relies on the available specification data and the recorded performance of the RX 7900 GRE to describe what each card offers.

Head-to-Head Benchmarks

With no shared benchmark results, a direct numerical comparison of the two cards is impossible. The database shows the RX 7900 GRE delivering an average benchmark score of 32,456 across ten tests. Its nearest rivals in the database, all AMD products, are the FirePro S10000 with an average score of 32,388, the FirePro S9300 X2 at 32,540, the Radeon RX 590 GME at 32,601, and the Radeon Pro 570X at 32,176. The RX 7900 GRE sits within 0.4 percent of these scores, trailing the RX 590 GME by 0.4 percent and the FirePro S9300 X2 by 0.3 percent, while leading the FirePro S10000 by 0.2 percent and the Radeon Pro 570X by 0.9 percent. These deltas are small, placing the RX 7900 GRE in a tightly clustered performance band around those cards in the aggregate.

The RX 7900 GRE’s individual test results show a wide spread across workloads. In 3DMark Steel Nomad DX12 it scores 4,814. Geekbench OpenCL returns 175,758, while Geekbench Vulkan returns 99,850. Passmark results include 139 for DirectX 10, 300 for DirectX 11, 107 for DirectX 12, and 310 for DirectX 9. The Passmark G2D score is 1,180, G3D is 27,089, and GPU Compute is 15,016. The DirectX 12 score is the lowest of the Passmark API tests, while DirectX 9 and DirectX 11 scores are substantially higher, indicating that the card’s measured performance varies by API generation. The Vulkan score in Geekbench is roughly 57 percent of the OpenCL score, a notable gap that suggests different driver or hardware efficiencies across those interfaces.

The LX ULTRA has no scores to compare. Its percentile rank of 50 is a placeholder, not evidence of performance, and the database records zero wins for either card in head-to-head tests. Any claim of superiority for either product cannot be grounded in measured benchmark results. The RX 7900 GRE has data; the LX ULTRA does not.

FP16 performance follows the same pattern: 91.96 TFLOPS for the RX 7900 GRE versus 49.15 TFLOPS for the LX ULTRA. The RX 7900 GRE also leads in pixel rate (359.2 GPixel/s versus 192.0 GPixel/s) and texture rate (718.4 GTexel/s versus 384.0 GTexel/s). Its memory bandwidth is higher at 576.0 GB/s compared to 432.0 GB/s, despite the LX ULTRA having more memory capacity. The RX 7900 GRE includes 80 ray tracing cores, a feature absent from the LX ULTRA’s listed specifications. It also has 320 texture mapping units and 160 render output units, versus 192 TMUs and 96 ROPs on the LX ULTRA. The RX 7900 GRE’s die is larger at 529 mm² on a 5 nm process with 57,700 million transistors, giving a transistor density of 109.1M per mm².

The Verdict

The recorded data indicates that the AMD Radeon RX 7900 GRE is a fully characterized product with substantial measured performance. Its average benchmark score of 32,456 places it at the 77th percentile, and its nearest rivals in the database are all within one percentage point, confirming that it sits in a competitive band of mid-pack GPUs. Its compute rates, pixel throughput, and memory bandwidth are all significantly higher than the LX ULTRA’s listed figures. The RX 7900 GRE also has ray tracing hardware, a feature the LX ULTRA does not list.

The Lisuan Tech LX ULTRA, by contrast, has no measured performance data. Its 24 GB memory capacity and 6,144 shading units are the only areas where it exceeds the RX 7900 GRE on paper, but the lower bandwidth, lower compute throughput, and slower pixel and texture rates indicate that those raw counts do not translate into higher performance. The LX ULTRA’s lower TDP of 225 W and single 16-pin connector suggest a more modest power delivery design, but without benchmark scores, its actual performance cannot be verified.

For users seeking a GPU with proven benchmark results, the database supports the RX 7900 GRE. It has scores across DirectX, OpenCL, Vulkan, and compute workloads, and its percentile rank reflects tested performance. The LX ULTRA is an active product with specifications on file, but the absence of any recorded test results means the database cannot confirm its capabilities. The RX 7900 GRE is the only card of the two with evidence of performance in the record.
