AMD Radeon RX 7700S vs Lisuan Tech LX ULTRA Comparison

AMD Radeon RX 7700S and Lisuan Tech LX ULTRA occupy very different positions in the current GPU landscape. The RX 7700S is a mobile-focused RDNA 3 part aimed at laptops, while the LX ULTRA is a desktop dual-slot card with a much larger memory pool. The recorded data shows substantial differences in compute resources, memory configuration, and power requirements, making them suitable for entirely separate use cases.

Architecture Differences

The two GPUs share a common manufacturing foundation: both are built on a 6 nm process at TSMC. Beyond that, the architectures diverge completely. The AMD Radeon RX 7700S uses the Navi 33 chip with RDNA 3.0 architecture, under the codename "Hotpink Bonefish." It belongs to the Navi Mobile generation within the RX 7000M lineup. The Lisuan Tech LX ULTRA uses a chip designated 7G105 with an architecture called TrueGPU, belonging to the 7G100 generation.

The cache and compute structures differ significantly. The RX 7700S implements 2048 shading units, 128 texture mapping units, and 64 render output units. It also includes 32 ray tracing cores. The LX ULTRA scales up in raw compute: 6144 shading units, 192 texture mapping units, and 96 render output units. The LX ULTRA does not list any dedicated ray tracing cores in the database.

Clock behavior also separates the two. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. The LX ULTRA has no recorded base, boost, or game clocks, so its operating frequencies remain unspecified in the database.

Both cards use GDDR6 memory at 2250 MHz with 18 Gbps effective speed. The bus width and total capacity differ, though. The RX 7700S uses a 128-bit bus with 8 GB, while the LX ULTRA uses a 192-bit bus with 24 GB. This gives the LX ULTRA 432.0 GB/s of bandwidth versus 288.0 GB/s for the RX 7700S.

The transistor counts and die sizes are only recorded for the RX 7700S: 13,300 million transistors on a 204 mm² die, resulting in a transistor density of 65.2 million per square millimeter. The LX ULTRA lists unknown values for transistors and die size.

API support shows some overlap. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 7700S supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The RX 7700S also supports RDNA 3 feature sets, and its predecessor is listed as Polaris Mobile.

The Verdict

The data points to two different buyers. The RX 7700S is an integrated mobile GPU with a 100 W TDP and no power connectors, designed for portable devices. Its display outputs are listed as "Portable Device Dependent," confirming its laptop-only nature. It uses an IGP slot width, meaning it is not a removable desktop card. This is a GPU for thin-and-light gaming laptops where power efficiency matters.

The LX ULTRA is a desktop card through and through. It is a dual-slot design measuring 268 mm in length, 112 mm in height, and 40 mm in width. It requires a 550 W power supply and a single 16-pin connector. It provides four DisplayPort 1.4a outputs, making it suitable for multi-monitor desktop setups.

For compute-heavy workloads, the LX ULTRA has clear theoretical advantages. Its 24 GB of memory is three times larger than the RX 7700S's 8 GB, and its 432.0 GB/s bandwidth is 50% higher. Its 6144 shading units triple the RX 7700S's 2048. Its FP32 throughput of 24.58 TFLOPS exceeds the RX 7700S's 20.48 TFLOPS, and its FP16 output of 49.15 TFLOPS beats the RX 7700S's 40.96 TFLOPS.

However, the RX 7700S has actual measured benchmark data, while the LX ULTRA has none. The RX 7700S scores 2185 in 3DMark Steel Nomad DX12, 62983 in Geekbench OpenCL, and 36380 in Geekbench Vulkan. Its 78th percentile ranking confirms it sits above half the GPUs in the database. The LX ULTRA's 50th percentile and zero average score reflect the absence of recorded performance data, not necessarily poor performance.

Users who need a laptop GPU with known benchmark performance should look at the RX 7700S. Users who need a desktop card with massive memory capacity for large datasets should look at the LX ULTRA, accepting that no benchmark data exists yet to quantify its real-world speed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7700S and the LX ULTRA. The winsA and winsB counters are both zero. However, the available data allows for a meaningful comparison through theoretical specifications and recorded scores.

The RX 7700S is the only one of the two with measured performance. Its 3DMark Steel Nomad DX12 score of 2185 represents a modern DirectX 12 workload, and its Geekbench OpenCL score of 62983 and Vulkan score of 36380 provide cross-API data points. These results place it at the 78th percentile of all GPUs, with an average score of 33849.

The nearest rivals for the RX 7700S give context to its standing. The AMD Radeon HD 7950 averages 33951, which is 0.3% higher. The AMD Radeon RX 480 averages 33997, 0.4% higher. The NVIDIA GeForce GTX 1060 5 GB averages 33694, which is 0.5% lower. The NVIDIA RTX A5000 averages 33622, 0.7% lower. The RX 7700S therefore sits in a tight cluster around these older desktop cards in terms of average benchmark score.

The LX ULTRA has no benchmark results, no average score, and no nearest rivals. Its 50th percentile ranking is the default baseline for a GPU with no recorded data. The theoretical specifications, however, suggest a much higher ceiling. Its FP32 throughput of 24.58 TFLOPS is 20% above the RX 7700S's 20.48 TFLOPS. Its texture rate of 384.0 GTexel/s is 20% higher than the RX 7700S's 320.0 GTexel/s. Its pixel rate of 192.0 GPixel/s is 20% above the RX 7700S's 160.0 GPixel/s.

Memory bandwidth favors the LX ULTRA by a wide margin. The 432.0 GB/s figure is exactly 1.5 times the RX 7700S's 288.0 GB/s. The 24 GB capacity versus 8 GB is a 3x difference. For workloads that are memory-bound, such as large model inference or high-resolution texture streaming, the LX ULTRA's advantage would be substantial.

The RX 7700S does hold one structural advantage beyond its measured benchmarks: it includes 32 ray tracing cores, while the LX ULTRA lists none. This means hardware-accelerated ray tracing is available on the RX 7700S, whereas the LX ULTRA would rely on any software fallback or lack the feature entirely.

Power efficiency favors the RX 7700S. It operates at 100 W TDP, while the LX ULTRA consumes 225 W. The RX 7700S achieves 20.48 TFLOPS at less than half the power envelope. It draws power from the motherboard or laptop power delivery, requiring no external connectors. The LX ULTRA needs a dedicated 16-pin connector and a 550 W power supply recommendation.

The release dates also tell a story. The RX 7700S launched on January 3, 2023, making it an established product with a track record. The LX ULTRA is dated March 16, 2026, a future release with no recorded performance validation. The RX 7700S has a clear predecessor in Polaris Mobile, while the LX ULTRA lists none. Neither GPU has a listed successor.

The overall picture is one of complementary strengths. The RX 7700S delivers proven performance, ray tracing hardware, and mobility in a 100 W package. The LX ULTRA offers triple the memory, higher bandwidth, more shading units, and higher theoretical throughput in a desktop form factor that requires 225 W. The absence of LX ULTRA benchmark data means its real-world performance cannot be confirmed, but its specifications place it in a different performance class on paper.
