AMD Ryzen Z2 GPU vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data contains no benchmark scores for either the AMD Ryzen Z2 GPU or the Lisuan Tech LX ULTRA, so there are no direct head-to-head performance measurements to compare. However, the specification sheets for both products reveal substantial differences in raw compute throughput. The Lisuan Tech LX ULTRA delivers 24.58 TFLOPS of FP32 performance, while the AMD Ryzen Z2 GPU delivers 8.294 TFLOPS. That places the LX ULTRA at roughly three times the FP32 throughput of the Ryzen Z2 GPU on paper.

In FP16 compute, the gap widens further. The LX ULTRA achieves 49.15 TFLOPS with a 2:1 ratio, while the Ryzen Z2 GPU is capped at 8.294 TFLOPS with a 1:1 ratio. The LX ULTRA therefore offers nearly six times the FP16 throughput. This suggests the LX ULTRA is designed for workloads that lean heavily on half-precision math, such as AI inference or certain compute tasks, whereas the Ryzen Z2 GPU treats FP16 as a passthrough mode without extra throughput.

Memory bandwidth is another area where the LX ULTRA holds a commanding lead. The LX ULTRA has 432.0 GB/s of bandwidth from 24 GB of GDDR6 memory on a 192-bit bus. The Ryzen Z2 GPU has 119.9 GB/s from 16 GB of LPDDR5X on a 128-bit bus. That is a 3.6x bandwidth advantage for the LX ULTRA. The practical effect is that memory-bound workloads, like high-resolution textures or large data sets, will favor the LX ULTRA substantially.

Pixel and texture throughput also favor the LX ULTRA. The LX ULTRA renders 192.0 GPixel/s and 384.0 GTexel/s, while the Ryzen Z2 GPU produces 86.40 GPixel/s and 129.6 GTexel/s. The LX ULTRA is ahead by 2.2x in pixel fillrate and nearly 3x in texture fillrate. The Ryzen Z2 GPU does hold one structural advantage: it includes 12 dedicated ray tracing cores, whereas the LX ULTRA lists no RT cores at all. That means the Ryzen Z2 GPU has a defined path for hardware-accelerated ray tracing, while the LX ULTRA relies on general compute for any ray tracing effects.

The two GPUs also differ in form factor and power delivery. The Ryzen Z2 GPU is a 28 W part with no power connectors, which indicates a compact, low-power design. The LX ULTRA is a 225 W dual-slot card with a single 16-pin connector and a suggested 550 W power supply. The LX ULTRA is physically larger at 268 mm in length, 112 mm in height, and 40 mm in width, while the Ryzen Z2 GPU has no recorded dimensions.

The Verdict

The data points to two completely different usage profiles. The Lisuan Tech LX ULTRA is the obvious choice for anyone who needs maximum raw compute, memory capacity, and bandwidth. Its 24 GB of GDDR6 memory, 432.0 GB/s bandwidth, and 24.58 TFLOPS FP32 performance make it suited for large-scale rendering, high-resolution textures, and compute-heavy tasks. The 2:1 FP16 ratio also indicates strong half-precision performance, which could benefit machine learning or scientific workloads that tolerate reduced precision.

The AMD Ryzen Z2 GPU, by contrast, is a low-power part with a 28 W TDP, no power connectors, and a single USB Type-C display output. Its 16 GB of LPDDR5X memory and 119.9 GB/s bandwidth are modest, but its 12 ray tracing cores give it a hardware feature that the LX ULTRA lacks entirely. For scenarios where power efficiency is critical, such as compact systems, handheld devices, or battery-powered platforms, the Ryzen Z2 GPU is the only viable option. Its 4 nm process node from TSMC also suggests a modern, dense design, whereas the LX ULTRA uses a 6 nm process.

The LX ULTRA delivers superior performance per the recorded specifications, but the Ryzen Z2 GPU offers a feature set that the LX ULTRA cannot match in ray tracing. Neither product has benchmark scores in the database, so the verdict rests entirely on specification-level analysis. The LX ULTRA wins on raw throughput, memory, and bandwidth. The Ryzen Z2 GPU wins on power efficiency, ray tracing hardware, and a more recent process node.

Architecture Differences

The AMD Ryzen Z2 GPU is built on the RDNA 3.0 architecture and uses the Hawk Point chip. It is fabricated on a 4 nm process at TSMC, with 25,390 million transistors on a 178 mm² die. That yields a transistor density of 142.6 million per square millimeter. The architecture supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which places it at the latest API feature levels.

The Lisuan Tech LX ULTRA uses a completely different architecture called TrueGPU, with the chip designation 7G105 and a generation label of 7G100. It is manufactured on a 6 nm process, also at TSMC, but the database records no transistor count or die size. The LX ULTRA supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, but only Vulkan 1.3, which is one version behind the Ryzen Z2 GPU.

The shader and compute layout differs sharply. The Ryzen Z2 GPU has 768 shading units, 48 texture mapping units, and 32 raster output units. It also has 12 ray tracing cores. The LX ULTRA has 6144 shading units, 192 TMUs, and 96 ROPs, but no ray tracing cores are recorded. The LX ULTRA's shading unit count is eight times that of the Ryzen Z2 GPU, which explains its much higher FP32 throughput. The lack of RT cores means the LX ULTRA must handle ray tracing through general-purpose shaders, which is typically slower than dedicated hardware.

Process node differences also matter. The Ryzen Z2 GPU's 4 nm node is smaller than the LX ULTRA's 6 nm node, which typically allows for higher density and better power efficiency. The Ryzen Z2 GPU's transistor density of 142.6M per mm² reflects that advantage. The LX ULTRA has no recorded density figure, so a direct comparison is impossible, but the larger node suggests lower density for the same design complexity.
