AMD Radeon RX 7700S vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the AMD Radeon RX 7700S, but no comparable test scores exist for the Lisuan Tech LX 7G100. The RX 7700S holds three measured results: a 3DMark Steel Nomad DX12 score of 2185, a Geekbench OpenCL score of 62983, and a Geekbench Vulkan score of 36380. Its average benchmark score across all tests is 33849, placing it in the 78th percentile of all GPUs tracked in the database.

The LX 7G100 has no benchmark entries in the database. Its average benchmark score is recorded as 0, and it sits in the 50th percentile by default. This absence of data means no direct head-to-head comparison can be drawn from measured performance. The RX 7700S, by contrast, has enough data to position it against several familiar rivals. It sits 0.3% behind the AMD Radeon HD 7950 (which averages 33951), 0.4% behind the AMD Radeon RX 480 (33997), 0.5% ahead of the NVIDIA GeForce GTX 1060 5 GB (33694), and 0.7% ahead of the NVIDIA RTX A5000 (33622). These are narrow margins, all within a single percentage point, indicating the RX 7700S clusters tightly with mid-range GPUs from previous generations.

The lack of any recorded scores for the LX 7G100 is itself a notable finding. A GPU that claims 24.58 TFLOPS of FP32 performance, a 192-bit memory bus, and 12 GB of GDDR6 memory has no verified performance footprint in the database. The RX 7700S, with 20.48 TFLOPS of FP32 and an 8 GB memory configuration, is fully characterized. This asymmetry means the benchmark section must rely on architectural inference rather than direct measurement.

Architecture Differences

The two GPUs come from different design philosophies. The RX 7700S uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi Mobile (RX 7000M) generation and is fabricated by TSMC on a 6 nm process. The die measures 204 mm² and contains 13,300 million transistors, yielding a transistor density of 65.2M per mm². The LX 7G100 uses a chip labeled 7G106 under an architecture called TrueGPU, also fabricated by TSMC on a 6 nm node. Its transistor count and die size are listed as unknown, so density cannot be calculated.

Core configurations differ substantially. The RX 7700S carries 2048 shading units, 128 texture mapping units, and 64 raster output units. It also includes 32 ray tracing cores. The LX 7G100 lists 6144 shading units, 192 TMUs, and 96 ROPs, which is three times the shading units and 1.5 times the TMUs and ROPs of the RX 7700S. No ray tracing core count is recorded for the LX 7G100, leaving its RT capability unquantified. The pixel rate for the RX 7700S is 160.0 GPixel/s versus 192.0 GPixel/s for the LX 7G100, and the texture rate is 320.0 GTexel/s versus 384.0 GTexel/s.

Memory configurations show clear divergence. The RX 7700S uses 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The LX 7G100 uses 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. Both run memory at 2250 MHz with 18 Gbps effective speed, but the wider bus gives the LX 7G100 a 50% bandwidth advantage. FP32 compute is listed at 20.48 TFLOPS for the RX 7700S and 24.58 TFLOPS for the LX 7G100, a 20% gap. FP16 figures are 40.96 TFLOPS and 49.15 TFLOPS respectively, both at a 2:1 ratio.

Power and physical design separate the two further. The RX 7700S is rated at 100 W TDP, uses an IGP slot width, has no power connectors, and its display outputs are listed as portable device dependent. The LX 7G100 is rated at 225 W TDP, uses a dual-slot cooler, requires a single 8-pin power connector, and suggests a 550 W power supply. It measures 294 mm in length, 120 mm in height, and 49 mm in width, with four DisplayPort 1.4a outputs. Both use a PCIe 4.0 x16 bus interface. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6, but the RX 7700S supports Vulkan 1.4 while the LX 7G100 supports Vulkan 1.3.

Release timing also differs. The RX 7700S launched on 2023-01-03 and lists Polaris Mobile as its predecessor. The LX 7G100 has a release date of 2026-06-17 with no predecessor on record. Both are marked as active production.

FAQ

Q: Which GPU has higher peak FP32 compute?

A: The LX 7G100 lists 24.58 TFLOPS of FP32 performance, compared to 20.48 TFLOPS for the RX 7700S. That is a 20% higher figure on paper, though no benchmark data exists to confirm real-world scaling.

Q: How do the memory subsystems compare?

A: The RX 7700S has 8 GB of GDDR6 on a 128-bit bus with 288.0 GB/s bandwidth. The LX 7G100 has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. Both run at 2250 MHz with 18 Gbps effective memory speed, so the bandwidth difference comes entirely from the wider bus.

Q: What is the performance percentile of each GPU?

A: The RX 7700S sits in the 78th percentile of all GPUs in the database, with an average benchmark score of 33849. The LX 7G100 has no recorded benchmark scores, an average score of 0, and a 50th percentile placement.

Q: Do both GPUs support the same graphics APIs?

A: Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. They differ in Vulkan support: the RX 7700S supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3.

Q: How do power requirements differ?

A: The RX 7700S is rated at 100 W TDP with no power connectors and an IGP slot width. The LX 7G100 is rated at 225 W TDP, requires one 8-pin connector, uses a dual-slot design, and lists a 550 W suggested power supply.

Q: Which GPU has more shading units?

A: The LX 7G100 has 6144 shading units, exactly three times the 2048 shading units of the RX 7700S. It also has more TMUs (192 versus 128) and ROPs (96 versus 64).

The Verdict

The recorded data supports only one fully verified performer: the RX 7700S. Its average benchmark score of 33849 and 78th percentile placement come from three distinct tests. Its nearest rivals are all within a single percentage point of its average score, which means it performs essentially on par with the AMD Radeon HD 7950, AMD Radeon RX 480, NVIDIA GeForce GTX 1060 5 GB, and NVIDIA RTX A5000. The margins range from 0.7% ahead to 0.4% behind, so none of these competitors holds a meaningful edge.

The LX 7G100 cannot be placed on the same performance scale because no benchmark scores exist for it in the database. Its architectural specifications suggest a higher theoretical ceiling: more shading units, more memory, wider bus, higher pixel and texture rates, and higher FP32 throughput. But theoretical specifications do not translate automatically into measured performance, and the database contains no evidence of that translation.

The RX 7700S also has the advantage of verified compatibility with modern API versions, including Vulkan 1.4. The LX 7G100 stops at Vulkan 1.3. For users who prioritize measured, reproducible performance data, the RX 7700S is the only option with a track record. For users who prioritize raw specification counts, the LX 7G100 presents a larger configuration on paper. The data cannot confirm that the larger configuration delivers proportionally larger results.

Where Each One Wins

The RX 7700S wins in every category backed by measured data. Its average benchmark score of 33849 is real and reproducible across three tests. Its 78th percentile ranking reflects actual placement among all tracked GPUs. Its nearest rivals show it trading blows within a one percentage point window, which means it is a known quantity in the mid-range performance band. It also supports Vulkan 1.4, a newer API version than the LX 7G100, and does so within a 100 W TDP envelope using an IGP form factor with no external power connectors. For mobile or compact systems where power draw and physical footprint matter, the RX 7700S has a clear structural advantage.

The LX 7G100 wins on raw specification counts. It has three times the shading units, 1.5 times the TMUs and ROPs, 50% more memory capacity, and 50% more memory bandwidth. Its FP32 output is 20% higher, its pixel rate is 20% higher, and its texture rate is 20% higher. It also offers 12 GB of VRAM against 8 GB, which matters for workloads that exceed the smaller frame buffer. Its dual-slot cooler and 8-pin connector indicate a desktop-oriented design with room for higher sustained power draw. None of these advantages are confirmed by benchmark scores, but the specification sheet is consistently in its favor.

The split is therefore clean. The RX 7700S wins where verification matters: measured scores, percentile ranking, API currency, and power efficiency. The LX 7G100 wins where potential matters: raw counts, memory capacity, bandwidth, and compute ceilings. The database records the former as fact and the latter as specification only.
