Architecture Differences

The AMD Ryzen Z1 Extreme GPU and the Lisuan Tech LX ULTRA represent two distinct architectural approaches. The Z1 Extreme is built on the RDNA 3.0 architecture, while the LX ULTRA uses an architecture labeled "TrueGPU." The process nodes differ: the Z1 Extreme uses a 4 nm process from TSMC, whereas the LX ULTRA uses a 6 nm process from TSMC. The Z1 Extreme's die size is 178 mm² with 25,390 million transistors, resulting in a transistor density of 142.6M per mm². The LX ULTRA's transistor count and die size are listed as unknown in the database.

The memory subsystems are fundamentally different. The Z1 Extreme uses 16 GB of LPDDR5 memory on a 64-bit bus, achieving 51.20 GB/s bandwidth. The LX ULTRA uses 24 GB of GDDR6 memory on a 192-bit bus, achieving 432.0 GB/s bandwidth. This is a substantial difference in both capacity and throughput.

Compute resources also differ significantly. The Z1 Extreme has 768 shading units, 48 TMUs, and 32 ROPs, plus 12 dedicated RT cores. The LX ULTRA has 6,144 shading units, 192 TMUs, and 96 ROPs, with no RT core count listed. The LX ULTRA's pixel rate is 192.0 GPixel/s versus 86.40 GPixel/s for the Z1 Extreme.

The API support is similar in some respects: both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Z1 Extreme supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The Z1 Extreme has a boost clock of 2700 MHz and a base clock of 800 MHz, while the LX ULTRA has no base or boost clock listed; its memory clock is 2250 MHz with 18 Gbps effective speed.

Power characteristics are markedly different. The Z1 Extreme has a TDP of 30 W and requires no power connectors. The LX ULTRA has a TDP of 225 W, requires a 1x 16-pin power connector, and has a suggested PSU of 550 W. The physical dimensions also differ: the Z1 Extreme measures 280 mm in length, 111 mm in height, and 21 mm in width. The LX ULTRA measures 268 mm in length, 112 mm in height, and 40 mm in width, with a dual-slot form factor.

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Ryzen Z1 Extreme GPU and the Lisuan Tech LX ULTRA. The database contains no win counts for either GPU in this comparison. However, the specification-level data allows for a clear performance projection.

In FP32 compute, the LX ULTRA delivers 24.58 TFLOPS, which is 16.286 TFLOPS higher than the Z1 Extreme's 8.294 TFLOPS. In FP16 compute, the LX ULTRA delivers 49.15 TFLOPS versus 16.59 TFLOPS for the Z1 Extreme. The LX ULTRA is roughly three times higher in both metrics.

Memory bandwidth is another area where the LX ULTRA dominates. Its 432.0 GB/s bandwidth is 380.8 GB/s higher than the Z1 Extreme's 51.20 GB/s. The LX ULTRA's pixel rate of 192.0 GPixel/s is 105.6 GPixel/s higher than the Z1 Extreme's 86.40 GPixel/s. The texture rate difference is 254.4 GTexel/s in favor of the LX ULTRA.

The Z1 Extreme does hold advantages in certain areas. Its 4 nm process node is smaller than the LX ULTRA's 6 nm node, which contributes to its much lower 30 W TDP compared to 225 W. The Z1 Extreme also has 12 RT cores, while the LX ULTRA has no RT core count listed in the database. The Z1 Extreme supports Vulkan 1.4, a newer version than the LX ULTRA's Vulkan 1.3 support.

The Z1 Extreme also has a smaller physical footprint: 21 mm width versus 40 mm width for the LX ULTRA. The Z1 Extreme's length of 280 mm is slightly longer than the LX ULTRA's 268 mm, but the Z1 Extreme is a single-slot-width design without requiring external power connectors.

The data indicates a clear performance hierarchy between these two GPUs. The Lisuan Tech LX ULTRA delivers substantially higher compute throughput, memory bandwidth, pixel rate, and texture rate. Its 24.58 TFLOPS FP32 and 432.0 GB/s bandwidth place it in a different performance class than the Z1 Extreme's 8.294 TFLOPS and 51.20 GB/s.

The AMD Ryzen Z1 Extreme GPU is a low-power part with a 30 W TDP and no external power connectors. It is designed for compact, power-constrained environments. Its 4 nm process node and 12 RT cores provide architectural advantages, and it supports Vulkan 1.4. The LX ULTRA, by contrast, requires a 225 W TDP, a 1x 16-pin power connector, and a 550 W suggested PSU. It uses a dual-slot design and is physically wider at 40 mm.

For users who need maximum rendering performance, memory capacity, and bandwidth, the LX ULTRA is the clear choice based on the recorded specifications. For users who prioritize low power draw, compact dimensions, and a newer Vulkan implementation, the Z1 Extreme has advantages. The Z1 Extreme also carries a launch MSRP of 699 USD, while the LX ULTRA has no listed MSRP in the database.
