AMD Radeon RX 7900 GRE vs Lisuan Tech LX PRO Comparison

The Verdict

The recorded data presents an unusual comparison. The AMD Radeon RX 7900 GRE is a fully characterized product with a substantial body of benchmark results, while the Lisuan Tech LX PRO is listed with no benchmark scores at all. The RX 7900 GRE achieves an average benchmark score of 32456 and sits in the 77th percentile of all GPUs in the database. The LX PRO holds a 50th percentile ranking with an average score of 0, indicating it has no recorded performance data.

For any workload requiring verified performance, the RX 7900 GRE is the only option with measurable results. Its 3DMark Steel Nomad DX12 score of 4814, Geekbench OpenCL score of 175758, and Passmark G3D score of 27089 provide concrete reference points. The LX PRO cannot be evaluated for gaming, compute, or professional tasks based on the database, as it possesses no entries in any benchmark category.

The RX 7900 GRE also holds architectural advantages that are quantifiable. It uses a 5 nm process compared to the LX PRO's 6 nm node. The AMD part delivers 45.98 TFLOPS of FP32 performance versus 24.58 TFLOPS for the LX PRO, a 21.40 TFLOPS gap. Its 576.0 GB/s memory bandwidth exceeds the LX PRO's 432.0 GB/s. The RX 7900 GRE supports PCIe 4.0 x16, DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the LX PRO supports DirectX 12 Ultimate and OpenGL 4.6 but only Vulkan 1.3.

The Lisuan Tech LX PRO does offer a larger 24 GB memory pool versus 16 GB, and a lower 225 W TDP versus 260 W. However, without any benchmark data, these specifications cannot be translated into real-world performance advantages. The RX 7900 GRE is the defensible choice for any user requiring verified capability.

Architecture Differences

The two GPUs diverge fundamentally in their underlying designs. The AMD Radeon RX 7900 GRE belongs to the Radeon RX 7000 series and uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It is fabricated by TSMC on a 5 nm process and contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1M per mm². The Lisuan Tech LX PRO uses a 7G105 chip based on TrueGPU architecture from the 7G100 generation, also fabricated by TSMC but on a 6 nm process. Its transistor count and die size are listed as unknown.

The compute configurations differ substantially. The RX 7900 GRE contains 5120 shading units, 320 texture mapping units, 160 render output units, and 80 ray tracing cores. The LX PRO has a higher count of 6144 shading units but fewer fixed-function units: 192 TMUs and 96 ROPs. It lists no ray tracing cores. This arrangement suggests the LX PRO dedicates more resources to general-purpose shading but less to texture and pixel throughput.

Clock behavior cannot be compared directly. The RX 7900 GRE has a base clock of 1287 MHz, a boost clock of 2245 MHz, and a game clock of 1880 MHz. The LX PRO has no base, boost, or game clock listed. Both parts run their memory at 2250 MHz with 18 Gbps effective, but the memory subsystems diverge in configuration. The RX 7900 GRE uses a 256-bit bus with 16 GB of GDDR6, producing 576.0 GB/s of bandwidth. The LX PRO uses a narrower 192-bit bus with 24 GB of GDDR6, resulting in 432.0 GB/s.

Pixel and texture rates reflect these differences. The RX 7900 GRE achieves 359.2 GPixel/s and 718.4 GTexel/s. The LX PRO delivers 192.0 GPixel/s and 384.0 GTexel/s. The FP32 throughput is 45.98 TFLOPS for the AMD part and 24.58 TFLOPS for the LX PRO, with corresponding FP16 rates of 91.96 TFLOPS and 49.15 TFLOPS, both at a 2:1 ratio.

Power and physical specifications also differ. The RX 7900 GRE has a 260 W TDP, requires two 8-pin power connectors, and suggests a 600 W power supply. It measures 276 mm in length, 110 mm in height, and 51 mm in width. The LX PRO has a 225 W TDP, uses a single 16-pin connector, and recommends a 550 W power supply. It is shorter at 248 mm, taller at 118 mm, and narrower at 48 mm. Both are dual-slot cards with PCIe 4.0 x16 interfaces. The RX 7900 GRE offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C outputs. The LX PRO provides 4x DisplayPort 1.4a outputs.

Head-to-Head Benchmarks

The head-to-head benchmark table contains no entries, and neither GPU records any wins in direct comparisons. The RX 7900 GRE nevertheless has a complete set of standalone benchmark scores, while the LX PRO has none. This absence of data is itself the most significant finding.

The RX 7900 GRE's 3DMark Steel Nomad DX12 score of 4814 places it in the upper tier of modern graphics cards. Its Geekbench OpenCL score of 175758 and Geekbench Vulkan score of 99850 indicate strong compute and graphics API performance. Passmark results show 27089 in G3D, 15016 in GPU compute, 1180 in G2D, and component-level scores of 310 in DirectX 9, 300 in DirectX 11, 139 in DirectX 10, and 107 in DirectX 12.

The nearest rivals to the RX 7900 GRE in the database are the AMD FirePro S10000 with an average score of 32388 and a delta of 0.2 percent, the AMD FirePro S9300 X2 at 32540 with a delta of -0.3 percent, the AMD Radeon RX 590 GME at 32601 with a delta of -0.4 percent, and the AMD Radeon Pro 570X at 32176 with a delta of 0.9 percent. The RX 7900 GRE's average score of 32456 sits within 1 percent of all these parts, indicating tight clustering in this performance band despite the architectural generation gap.

The LX PRO has no rivals listed and no benchmark scores to contextualize. Its 50th percentile ranking appears to be a default position rather than a measured outcome. Any performance comparison between these two cards must rely entirely on the RX 7900 GRE's recorded results and the LX PRO's architectural specifications.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins in every measurable performance category. Its FP32 throughput of 45.98 TFLOPS is nearly double the LX PRO's 24.58 TFLOPS. Pixel rate favors the RX 7900 GRE at 359.2 GPixel/s versus 192.0 GPixel/s, and texture rate favors it at 718.4 GTexel/s versus 384.0 GTexel/s. Memory bandwidth is higher on the AMD part at 576.0 GB/s, and it supports the newer Vulkan 1.4 API alongside DisplayPort 2.1 outputs.

The RX 7900 GRE also holds the advantage of verified performance data. Its 77th percentile ranking among all GPUs, average score of 32456, and complete benchmark suite provide concrete evidence of capability. The 3DMark Steel Nomad score of 4814 indicates strong DirectX 12 gaming performance, while the Geekbench OpenCL score of 175758 demonstrates robust compute throughput. The Passmark G3D score of 27089 confirms solid overall graphics capability.

The Lisuan Tech LX PRO wins in several specification categories without corresponding performance validation. Its 24 GB memory capacity exceeds the RX 7900 GRE's 16 GB, which could theoretically benefit large datasets or high-resolution textures. Its 6144 shading units outnumber the RX 7900 GRE's 5120, though this does not translate into higher measured throughput given the lower FP32 figure. The LX PRO's 225 W TDP is 35 W lower than the RX 7900 GRE's 260 W, and its 550 W suggested power supply is 50 W lower. Its 248 mm length makes it 28 mm shorter than the RX 7900 GRE's 276 mm, which could matter for compact cases.

The LX PRO's 192-bit memory bus and 432.0 GB/s bandwidth are both lower than the RX 7900 GRE's figures. Its 192 TMUs and 96 ROPs are fewer than the AMD part's 320 and 160. It lacks listed ray tracing cores, while the RX 7900 GRE includes 80. The LX PRO supports Vulkan 1.3, one version behind the RX 7900 GRE's Vulkan 1.4.

For users who prioritize verified performance, the RX 7900 GRE is the only rational selection. For users who require maximum memory capacity and are willing to accept unverified performance claims, the LX PRO offers a larger pool. The data does not support any scenario where the LX PRO outperforms the RX 7900 GRE, as no benchmark results exist to demonstrate such an outcome.
