AMD Ryzen Z2 Go GPU vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results for the AMD Ryzen Z2 Go GPU and the Lisuan Tech LX ULTRA. Both products hold a 50th percentile position among all GPUs in the database, and their average benchmark scores are recorded as zero. This means a direct performance comparison cannot be derived from measured test runs. Without benchmark scores, the analysis must rely on architectural specifications and theoretical throughput figures to characterize the relative strengths of each design.

The raw compute figures, however, indicate a massive disparity in raw throughput. The Lisuan Tech LX ULTRA delivers 24.58 TFLOPS of FP32 compute, while the AMD Ryzen Z2 Go GPU reaches 4.147 TFLOPS. That places the LX ULTRA at approximately 5.9 times the FP32 throughput of the Z2 Go GPU. In FP16, the LX ULTRA records 49.15 TFLOPS versus 8.294 TFLOPS for the Z2 Go GPU, again a near sixfold difference. These numbers are theoretical peak rates, but they establish the fundamental performance envelope of each part.

Pixel and texture throughput follow the same pattern. The LX ULTRA achieves 192.0 GPixel/s and 384.0 GTexel/s, compared to 86.40 GPixel/s and 129.6 GTexel/s for the Z2 Go GPU. The pixel rate advantage is 2.2 times, while the texture rate advantage is approximately 3 times. These figures suggest the LX ULTRA is designed for high-resolution, high-detail rendering, while the Z2 Go GPU targets a much lighter workload profile.

Memory bandwidth also diverges sharply. The LX ULTRA uses 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. The Z2 Go GPU uses 16 GB of LPDDR5 on a 128-bit bus, yielding 102.4 GB/s. The LX ULTRA provides 4.2 times the bandwidth, which is critical for texture-heavy scenes and large dataset workloads. The Z2 Go GPU's memory system is clearly optimized for lower power consumption rather than peak bandwidth.

Architecture Differences

The two GPUs belong to different architectural lineages. The AMD Ryzen Z2 Go GPU uses the Rembrandt+ chip with RDNA 2.0 architecture, a design from the Console GPU generation. The Lisuan Tech LX ULTRA uses the 7G105 chip with a proprietary "TrueGPU" architecture from the 7G100 generation. Both are fabricated on a 6 nm process at TSMC, but the transistor counts differ significantly: the Z2 Go GPU has 13,100 million transistors on a 208 mm² die, while the LX ULTRA's transistor count and die size are not recorded in the database.

The shading unit count is the most striking architectural difference. The LX ULTRA has 6,144 shading units, 192 texture mapping units, and 96 render output units. The Z2 Go GPU has 768 shading units, 48 TMUs, and 32 ROPs. This means the LX ULTRA has 8 times the shading units, 4 times the TMUs, and 3 times the ROPs. The LX ULTRA also includes no dedicated ray tracing cores in the database, while the Z2 Go GPU has 12 RT cores. This suggests the Z2 Go GPU implements hardware ray tracing acceleration, whereas the LX ULTRA may rely on compute-based methods or lacks RT support entirely.

Clock behavior also differs. The Z2 Go GPU has a base clock of 800 MHz and a boost clock of 2700 MHz, with memory clocked at 800 MHz (6.4 Gbps effective). The LX ULTRA has no base or boost clock recorded, only a memory clock of 2250 MHz (18 Gbps effective). This absence of core clock data for the LX ULTRA limits direct clock-to-clock comparisons, but the memory clock difference is substantial: 18 Gbps versus 6.4 Gbps effective, a 2.8 times higher data rate.

API support is similar but not identical. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Z2 Go GPU supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. This means the Z2 Go GPU has a slightly newer Vulkan version, which may matter for certain compute or rendering extensions.

Where Each One Wins

The AMD Ryzen Z2 Go GPU is positioned for efficiency and portability. Its 28 W TDP is dramatically lower than the LX ULTRA's 225 W, making it suitable for compact or power-constrained systems. It also features a single USB Type-C display output, which aligns with a minimal, integrated form factor. The 12 RT cores provide dedicated hardware for ray-traced effects, which the LX ULTRA lacks according to the recorded data. The Z2 Go GPU's 6 nm process and 13,100 million transistors on a 208 mm² die give it a transistor density of 63.0M per mm², a figure that reflects a dense, power-efficient design.

The Lisuan Tech LX ULTRA wins decisively on raw performance metrics. Its 24.58 TFLOPS FP32, 24 GB of GDDR6 memory, 432.0 GB/s bandwidth, and 192.0 GPixel/s pixel rate put it in a different performance class. It also offers a dual-slot cooling design, a 16-pin power connector, a suggested 550 W power supply, and a PCIe 4.0 x16 interface. The four DisplayPort 1.4a outputs and physical dimensions of 268 mm length, 112 mm height, and 40 mm width indicate a full-size add-in card intended for desktop workstations or high-end gaming rigs.

In terms of memory capacity, the LX ULTRA provides 24 GB versus 16 GB, and the memory type is GDDR6 versus LPDDR5. The LX ULTRA's memory bandwidth of 432.0 GB/s is 4.2 times the Z2 Go GPU's 102.4 GB/s. For workloads that are memory-bandwidth bound, such as large texture sets or multi-sample rendering, the LX ULTRA holds a clear advantage. For workloads that are power-limited or require hardware ray tracing, the Z2 Go GPU offers features the LX ULTRA does not.

Specification Differences

The two GPUs differ across nearly every recorded specification field. The process node is identical (6 nm, TSMC), but the transistor count is only known for the Z2 Go GPU (13,100 million), with the LX ULTRA's value marked as unknown. Die size is similarly only known for the Z2 Go GPU at 208 mm². Transistor density is 63.0M / mm² for the Z2 Go GPU, while no value is recorded for the LX ULTRA.

Clock specifications diverge: the Z2 Go GPU has base and boost clocks (800 MHz and 2700 MHz), while the LX ULTRA has no core clocks recorded. Memory clocks are 800 MHz (6.4 Gbps effective) for the Z2 Go GPU versus 2250 MHz (18 Gbps effective) for the LX ULTRA. Memory size is 16 GB LPDDR5 against 24 GB GDDR6. Bus width is 128 bit for the Z2 Go GPU and 192 bit for the LX ULTRA. Bandwidth is 102.4 GB/s versus 432.0 GB/s.

Shading units are 768 versus 6,144, TMUs are 48 versus 192, and ROPs are 32 versus 96. The Z2 Go GPU has 12 RT cores; the LX ULTRA has none recorded. Pixel rate is 86.40 GPixel/s versus 192.0 GPixel/s. Texture rate is 129.6 GTexel/s versus 384.0 GTexel/s. FP32 is 4.147 TFLOPS versus 24.58 TFLOPS. FP16 is 8.294 TFLOPS versus 49.15 TFLOPS.

TDP is 28 W versus 225 W. The LX ULTRA has a dual-slot width, a 16-pin power connector, a suggested 550 W power supply, and a PCIe 4.0 x16 interface; the Z2 Go GPU has none of these recorded. Display outputs are 1x USB Type-C for the Z2 Go GPU and 4x DisplayPort 1.4a for the LX ULTRA. Vulkan support is 1.4 for the Z2 Go GPU and 1.3 for the LX ULTRA. The release dates are 2024-12-31 for the Z2 Go GPU and 2026-03-16 for the LX ULTRA. Both are marked as Active production status.
