AMD Radeon RX 7900 GRE vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data shows a highly unusual comparison situation. The AMD Radeon RX 7900 GRE has a complete benchmark profile, while the Lisuan Tech LX 7G100 has no recorded benchmark scores in the database. The head-to-head benchmark table is empty, and the win count stands at zero for both products.

The RX 7900 GRE posts an average benchmark score of 32,456 across its ten recorded tests. Its percentile ranking sits at 77, meaning it outperforms 77 percent of all GPUs in the database. The nearest rival data places it within a tight cluster: the AMD FirePro S10000 scores 32,388 (0.2 percent ahead), the AMD FirePro S9300 X2 scores 32,540 (0.3 percent behind), the AMD Radeon RX 590 GME scores 32,601 (0.4 percent behind), and the AMD Radeon Pro 570X scores 32,176 (0.9 percent ahead). These deltas are small, indicating the RX 7900 GRE sits in a densely packed performance band.

The LX 7G100 has an average benchmark score of 0 and a percentile rank of 50, which in this database context means it occupies the median position by default rather than by measured performance. With zero benchmarks recorded, there is no quantitative basis for a direct head-to-head score comparison. The data cannot confirm which product wins any single test.

For the RX 7900 GRE specifically, the strongest recorded result is in Geekbench OpenCL with a score of 175,758. Geekbench Vulkan follows at 99,850. The Passmark G3D test delivers 27,089, while Passmark GPU Compute reaches 15,016. The remaining Passmark scores are lower: DirectX 10 at 139, DirectX 11 at 300, DirectX 12 at 107, DirectX 9 at 310, and G2D at 1,180. The 3DMark Steel Nomad DX12 test records 4,814. These numbers establish a baseline for the RX 7900 GRE but provide no comparison point against the LX 7G100.

Architecture Differences

The two GPUs diverge sharply at the architectural level. The AMD Radeon RX 7900 GRE uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Navi III (RX 7000) generation. The Lisuan Tech LX 7G100 uses the 7G106 chip with an architecture labeled TrueGPU, and its generation is listed as 7G100.

Process technology differs as well. The RX 7900 GRE is fabricated on a 5 nm node at TSMC, while the LX 7G100 uses a 6 nm node, also at TSMC. The RX 7900 GRE contains 57,700 million transistors on a die size of 529 mm², resulting in a transistor density of 109.1M per mm². The LX 7G100 lists transistor count, die size, and density as unknown, so no comparison is possible on those metrics.

Clock behavior also differs. The RX 7900 GRE has a full clock specification: base at 1287 MHz, boost at 2245 MHz, and game clock at 1880 MHz. The LX 7G100 has no base, boost, or game clock recorded. Both GPUs list memory clock at 2250 MHz with 18 Gbps effective, so memory clock is one point of parity.

Shader and compute resources favor different designs in different ways. The RX 7900 GRE has 5,120 shading units, 320 texture mapping units, and 160 raster operation units. The LX 7G100 has 6,144 shading units, 192 TMUs, and 96 ROPs. The LX 7G100 leads in shading units by 1,024, but the RX 7900 GRE leads in TMUs by 128 and in ROPs by 64. The RX 7900 GRE also has 80 ray tracing cores, while the LX 7G100 has none listed.

Compute throughput numbers reflect these differences. The RX 7900 GRE delivers 45.98 TFLOPS FP32 and 91.96 TFLOPS FP16 (2:1 ratio). The LX 7G100 delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio). The RX 7900 GRE is roughly 87 percent ahead in FP32 and FP16 throughput. Pixel rate for the RX 7900 GRE is 359.2 GPixel/s versus 192.0 GPixel/s for the LX 7G100, a 67 percent advantage. Texture rate is 718.4 GTexel/s versus 384.0 GTexel/s, a similar margin.

API support shows both cards reach DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 7900 GRE supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3, a one-version difference.

The two cards also differ in memory clock, though both list 2250 MHz with 18 Gbps effective, so that field is identical. The RX 7900 GRE has a higher pixel rate, texture rate, and compute throughput across the board. The LX 7G100 counters with more shading units, a smaller physical footprint in width, and lower power draw.

The Verdict

The data supports a clear choice for the AMD Radeon RX 7900 GRE based on measured performance. It has ten recorded benchmark scores, an average score of 32,456, and a percentile rank of 77. The Lisuan Tech LX 7G100 has no recorded benchmarks, an average score of 0, and a default percentile rank of 50. Without any measured scores, the LX 7G100 cannot be positioned competitively against the RX 7900 GRE in the database.

The RX 7900 GRE also leads in raw specification metrics that typically translate to performance. It has 87 percent higher FP32 throughput (45.98 TFLOPS versus 24.58 TFLOPS), 67 percent higher pixel rate (359.2 GPixel/s versus 192.0 GPixel/s), and 87 percent higher texture rate (718.4 GTexel/s versus 384.0 GTexel/s). Its memory bandwidth of 576.0 GB/s exceeds the LX 7G100's 432.0 GB/s by 33 percent. It includes 80 ray tracing cores, which the LX 7G100 lacks entirely.

The LX 7G100 does hold advantages in specific areas. Its 6,144 shading units exceed the RX 7900 GRE's 5,120 by 1,024. It draws 225 W versus 260 W, uses a single 8-pin connector instead of two, and suggests a 550 W PSU rather than 600 W. It also offers four DisplayPort 1.4a outputs, while the RX 7900 GRE offers a mix of HDMI, DisplayPort 2.1, and USB Type-C.

For a user selecting based on recorded database performance, the RX 7900 GRE is the only option with measured results. For a user prioritizing raw shading unit count or lower power draw, the LX 7G100 has those specific specification advantages. The RX 7900 GRE's launch MSRP of 549 USD provides a reference point, though the LX 7G100 has no listed launch price.

Where Each One Wins

The AMD Radeon RX 7900 GRE wins in every measured benchmark category by default, since the LX 7G100 has no benchmark scores. Its 3DMark Steel Nomad DX12 score of 4,814, Geekbench OpenCL score of 175,758, and Geekbench Vulkan score of 99,850 establish a performance baseline. The Passmark G3D score of 27,089 and GPU Compute score of 15,016 add further context. The RX 7900 GRE also wins on memory bandwidth, pixel rate, texture rate, FP32 and FP16 throughput, ray tracing cores, and Vulkan version support.

The Lisuan Tech LX 7G100 wins in shading unit count with 6,144 versus 5,120. It also wins on power efficiency metrics: lower TDP at 225 W versus 260 W, fewer power connectors (one 8-pin versus two), and a lower suggested PSU (550 W versus 600 W). It offers more display outputs at four DisplayPort 1.4a connections, though the RX 7900 GRE's outputs include newer DisplayPort 2.1 and HDMI 2.1a. The LX 7G100 is also slightly narrower at 49 mm versus 51 mm, though longer and taller.

The LX 7G100 wins on physical dimensions in one axis and power draw in all three power-related fields. The RX 7900 GRE wins in compute performance, memory capacity and bandwidth, ray tracing, API version, and every recorded benchmark. The two cards share PCIe 4.0 x16 interfaces, GDDR6 memory type, dual-slot designs, and identical memory clocks at 2250 MHz with 18 Gbps effective. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6.
