AMD Ryzen Z2 GPU vs Lisuan Tech LX MAX Comparison

AMD Ryzen Z2 GPU and Lisuan Tech LX MAX occupy very different positions in the database, with the former built for low-power integrated-class duty and the latter designed as a high-throughput discrete board. The recorded specifications show two products that share the same DirectX 12 Ultimate feature level but diverge sharply in almost every physical and computational metric. The Z2 GPU is a 28 W part on a 4 nm TSMC process, while the LX MAX is a 225 W dual-slot card on a 6 nm TSMC process with a 16-pin power connector and a recommended 550 W power supply. Their average benchmark scores are both recorded as zero, and both sit at the 50th percentile among all GPUs in the database, so the analysis below relies entirely on the architectural and specification data rather than measured frame rates.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two parts, so the comparison must be drawn from their calculated throughput figures. The most striking gap appears in FP32 compute. The LX MAX delivers 24.58 TFLOPS, which is roughly three times the 8.294 TFLOPS of the Z2 GPU. In practical terms, the LX MAX carries a 16.286 TFLOPS advantage in single-precision floating-point work. That margin translates directly to raw shader throughput, as the LX MAX has 6144 shading units against 768 for the Z2 GPU, an 8x difference in shader count.

Texture and pixel throughput follow the same pattern. The LX MAX posts 384.0 GTexel/s and 192.0 GPixel/s, while the Z2 GPU manages 129.6 GTexel/s and 86.40 GPixel/s. The LX MAX is therefore about 2.96x faster in texture fill and 2.22x faster in pixel fill. These are the numbers that matter for resolution scaling and heavy post-processing effects. The Z2 GPU, despite its much lower power envelope, still achieves respectable fill rates for its class, but it cannot approach the dedicated card's output.

Memory bandwidth shows a different kind of separation. The LX MAX uses 12 GB of GDDR6 on a 192-bit bus, producing 432.0 GB/s of bandwidth. The Z2 GPU uses 16 GB of LPDDR5X on a 128-bit bus, producing 119.9 GB/s. That is a 312.1 GB/s gap, or roughly 3.6x more bandwidth for the LX MAX. The Z2 GPU does counter with 4 GB more capacity, which can matter for large working sets, but the bandwidth deficit limits how quickly it can feed its shaders.

The FP16 comparison is notable because the two parts handle half-precision differently. The Z2 GPU delivers FP16 at a 1:1 ratio with FP32, meaning 8.294 TFLOPS. The LX MAX delivers FP16 at a 2:1 ratio, meaning 49.15 TFLOPS. That puts the LX MAX ahead by 40.856 TFLOPS in half-precision work, a roughly 5.9x advantage. Applications that use FP16 heavily, such as certain compute workloads, would see an outsized benefit from the LX MAX.

Where Each One Wins

The Z2 GPU wins on power efficiency and physical footprint. Its 28 W TDP is 197 W lower than the LX MAX's 225 W TDP. It requires no power connectors, while the LX MAX needs a single 16-pin connector. The Z2 GPU also uses a 4 nm process, which is smaller than the 6 nm node used by the LX MAX, and it fits into a 178 mm² die with 25,390 million transistors. The LX MAX has no recorded transistor count or die size, so a direct density comparison is not possible, but the process node advantage is clear.

The Z2 GPU also offers a 16 GB memory pool, which is 4 GB larger than the LX MAX's 12 GB. For workloads that fit within the bandwidth limit, that extra capacity can hold larger textures, larger datasets, or more resident geometry. The Z2 GPU uses unified LPDDR5X memory, which is typical for a low-power console-class part, and it outputs video through a single USB Type-C connection.

The LX MAX wins on raw compute, memory bandwidth, and display connectivity. Its 432.0 GB/s bandwidth is more than triple the Z2 GPU's figure, and its 24.58 TFLOPS FP32 output is nearly triple. It also provides four DisplayPort 1.4a outputs, whereas the Z2 GPU has a single USB Type-C. The LX MAX is a dual-slot card measuring 248 mm in length, 118 mm in height, and 48 mm in width, so it is a substantial physical unit, but that size buys a 192-bit memory bus and 192 texture mapping units against 48 for the Z2 GPU.

The LX MAX also supports Vulkan 1.3, while the Z2 GPU supports Vulkan 1.4. That is one area where the newer part, the Z2 GPU released in December 2024, leads the LX MAX, which has a release date of March 2026. The Z2 GPU's newer Vulkan revision suggests more recent API feature coverage, though both support DirectX 12 Ultimate and OpenGL 4.6.

Architecture Differences

The Z2 GPU uses the RDNA 3.0 architecture on AMD's Hawk Point chip. It is classified in the database as a Console GPU generation. It has 768 shading units, 48 TMUs, 32 ROPs, and 12 ray tracing cores. The architecture supports FP16 at a 1:1 ratio with FP32, meaning it does not double-rate half-precision operations. Its process node is 4 nm at TSMC, and it integrates 25,390 million transistors on a 178 mm² die. The transistor density works out to 142.6 million transistors per square millimeter.

The LX MAX uses an architecture labeled TrueGPU on a chip designated 7G106, part of the 7G100 generation. Its manufacturer is listed as unknown. It has 6144 shading units, 192 TMUs, and 96 ROPs, but no ray tracing cores are recorded. The FP16 ratio is 2:1, meaning it can execute twice as many half-precision operations as single-precision operations per clock. Its process node is 6 nm at TSMC, but the transistor count and die size are both unknown, so no density figure can be calculated.

The ray tracing situation is a meaningful difference. The Z2 GPU has 12 dedicated RT cores, while the LX MAX has none recorded. For DirectX 12 Ultimate workloads that use ray tracing, the Z2 GPU has dedicated hardware, whereas the LX MAX would have to rely on compute shaders or other methods. The LX MAX compensates with far more shading units and raw FP32 throughput, which can help in non-RT rasterization and compute-heavy scenes.

Memory architecture also differs fundamentally. The Z2 GPU uses LPDDR5X, a low-power memory type, on a 128-bit bus. The LX MAX uses GDDR6, a dedicated graphics memory type, on a 192-bit bus. The memory clock figures reflect this: the Z2 GPU runs at 937 MHz with 7.5 Gbps effective, while the LX MAX runs at 2250 MHz with 18 Gbps effective. The GDDR6 solution produces far higher bandwidth, while the LPDDR5X solution keeps power consumption low.

The Verdict

The data points to a clear split by intended use. The AMD Ryzen Z2 GPU is a low-power, compact solution with 16 GB of unified LPDDR5X memory, 12 ray tracing cores, and a 28 W TDP. It fits scenarios where power draw, heat, and physical space are tightly constrained. Its 8.294 TFLOPS of FP32 compute and 119.9 GB/s of bandwidth are modest, but its 4 nm process and lack of external power connectors make it a practical choice for small form factor systems. The Vulkan 1.4 support and the December 2024 release date also place it as the newer API implementation of the two.

The Lisuan Tech LX MAX is a high-power discrete card built for throughput. Its 24.58 TFLOPS FP32, 49.15 TFLOPS FP16, 432.0 GB/s bandwidth, and 384.0 GTexel/s texture rate put it in a different performance class entirely. The 225 W TDP, 16-pin connector, and 550 W suggested PSU indicate a system with substantial power delivery. The lack of ray tracing cores is a notable gap, but the massive shader count and fill rates make it the stronger choice for rasterization-heavy and compute-heavy workloads. The four DisplayPort 1.4a outputs also support multi-monitor setups in ways the single USB Type-C output on the Z2 GPU cannot.

The database shows no benchmark wins for either part and no direct head-to-head results, so the verdict rests on specification comparison. Users who need maximum compute, bandwidth, and display connectivity should look to the LX MAX. Users who need a low-power part with ray tracing support, more memory capacity, and no external power requirement should look to the Z2 GPU. The two are not direct competitors; they serve opposite ends of the power and performance spectrum.
