AMD Radeon RX 7900 GRE vs Lisuan Tech LX MAX Comparison

The Verdict

The recorded data presents a stark contrast between two actively produced graphics cards. The AMD Radeon RX 7900 GRE is a fully specified, high-performance part with extensive benchmark coverage, while the Lisuan Tech LX MAX is a newer, partially documented product with no recorded benchmark scores. The RX 7900 GRE holds an average benchmark score of 32,456 and a percentile rank of 77 against all GPUs, placing it firmly in the upper tier of the database. The Lisuan Tech LX MAX has an average benchmark score of 0 and a percentile rank of 50, meaning its performance cannot be quantified from current measurements.

The RX 7900 GRE is the only card with verifiable performance data. Its nearest rivals in the database include the AMD FirePro S10000 with an average score of 32,388 (delta of 0.2 percent ahead), the AMD FirePro S9300 X2 at 32,540 (0.3 percent behind), and the AMD Radeon RX 590 GME at 32,601 (0.4 percent behind). The RX 7900 GRE sits within a narrow performance band around these scores, separated by less than one percent in either direction. This indicates a tightly contested group where the RX 7900 GRE neither dominates nor falls behind its closest competitors by a meaningful margin.

For the Lisuan Tech LX MAX, the absence of benchmark results means the database cannot assign it a performance tier. Its specifications suggest a different positioning, but without scores, no comparative verdict is possible. Users seeking a card with demonstrated performance should select the RX 7900 GRE. The Lisuan Tech LX MAX remains an unquantified option whose real-world behavior is not yet reflected in the database.

Architecture Differences

The two cards diverge fundamentally at the architecture 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 generation within the Radeon RX 7000 series. The chip is manufactured on a 5 nm process at TSMC, with 57,700 million transistors packed into a 529 mm² die, yielding a transistor density of 109.1 million transistors per square millimeter. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Lisuan Tech LX MAX uses a 7G106 chip built on an architecture labeled TrueGPU, belonging to the 7G100 generation. It is fabricated on a 6 nm process at TSMC, but its transistor count, die size, and transistor density are all listed as unknown. This represents a less mature product in terms of disclosed information. The card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, one version behind the RX 7900 GRE in Vulkan support.

The RX 7900 GRE includes 80 ray tracing cores, a feature absent from the LX MAX's specifications, which list no ray tracing core count. The RX 7900 GRE also has a predecessor (Navi II) and a successor (Navi IV) in its lineage, while the LX MAX has neither documented. The RX 7900 GRE was released on 2023-07-26, while the LX MAX has a release date of 2026-03-16, making it a substantially later product.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two cards. The headToHeadBenchmarks field is empty, and the win counts for both cards are zero. However, the RX 7900 GRE has an extensive standalone benchmark profile that provides context for its capabilities.

In 3DMark Steel Nomad DX12, the RX 7900 GRE scores 4,814 points. Geekbench OpenCL returns a score of 175,758, while Geekbench Vulkan records 99,850 points. In Passmark tests, the card scores 139 in DirectX 10, 300 in DirectX 11, 107 in DirectX 12, 310 in DirectX 9, 1,180 in G2D, 27,089 in G3D, and 15,016 in GPU Compute. These numbers represent the only empirical performance data available for either card.

The RX 7900 GRE's compute throughput is substantial. Its FP32 rate reaches 45.98 TFLOPS, while FP16 reaches 91.96 TFLOPS with a 2:1 ratio. Pixel rate is 359.2 GPixel/s, and texture rate is 718.4 GTexel/s. The LX MAX, by contrast, lists an FP32 rate of 24.58 TFLOPS and FP16 of 49.15 TFLOPS, with pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s. These are raw specification differences, not benchmark results, but they indicate the RX 7900 GRE has roughly double the compute throughput in these metrics.

The LX MAX has no benchmark scores recorded, so no comparison can be made on actual measured performance. The RX 7900 GRE's percentile rank of 77 versus the LX MAX's percentile rank of 50 reflects this data asymmetry, though the LX MAX's percentile is not based on any test results.

Specification Differences

The two cards differ across nearly every measurable specification. Memory capacity favors the RX 7900 GRE with 16 GB of GDDR6, while the LX MAX offers 12 GB of GDDR6. Memory bus width is 256 bit for the RX 7900 GRE versus 192 bit for the LX MAX, resulting in bandwidth of 576.0 GB/s versus 432.0 GB/s respectively. Both use the same memory clock of 2250 MHz with 18 Gbps effective speed.

Shading units favor the LX MAX at 6,144 versus 5,120 for the RX 7900 GRE, but texture mapping units favor the RX 7900 GRE at 320 versus 192, and raster output units favor the RX 7900 GRE at 160 versus 96. The RX 7900 GRE has 80 ray tracing cores; the LX MAX has none listed. Pixel rate is 359.2 GPixel/s for the RX 7900 GRE against 192.0 GPixel/s for the LX MAX. Texture rate is 718.4 GTexel/s versus 384.0 GTexel/s. FP32 is 45.98 TFLOPS versus 24.58 TFLOPS, and FP16 is 91.96 TFLOPS versus 49.15 TFLOPS.

Power draw differs as well. The RX 7900 GRE has a TDP of 260 W with a suggested power supply of 600 W and two 8-pin connectors. The LX MAX has a TDP of 225 W with a suggested power supply of 550 W and a single 16-pin connector. Both cards are dual-slot designs, and both use a PCIe 4.0 x16 bus interface.

Display outputs differ significantly. The RX 7900 GRE provides one HDMI 2.1a port, two DisplayPort 2.1 ports, and one USB Type-C port. The LX MAX provides four DisplayPort 1.4a ports, with no HDMI or USB Type-C. Physical dimensions also differ: the RX 7900 GRE measures 276 mm in length, 110 mm in height, and 51 mm in width, while the LX MAX measures 248 mm in length, 118 mm in height, and 48 mm in width.

The RX 7900 GRE has a launch MSRP of 549 USD. The LX MAX has no launch MSRP recorded. The RX 7900 GRE's architecture is RDNA 3.0 with a 5 nm process; the LX MAX uses TrueGPU architecture on a 6 nm process. The RX 7900 GRE is manufactured by AMD, while the LX MAX's manufacturer is listed as Unknown.
