AMD Radeon RX 7800 XT vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison because the Lisuan Tech LX 7G100 has no benchmark entries in the database. Its average benchmark score is recorded as 0, with no individual test results. The AMD Radeon RX 7800 XT, by contrast, has a full set of measurements across multiple benchmark suites. The RX 7800 XT averages 11627 points across those tests, placing it in the 51st percentile of all GPUs. The LX 7G100 sits at the 50th percentile, though this is based on no recorded performance data.

Without head-to-head benchmark results for the LX 7G100, direct score comparisons cannot be made. The RX 7800 XT's individual results show a wide spread across test types. In Passmark G3D it scores 24176, while in Passmark G2D it scores 1177. Its compute result is 13473 in Passmark GPU Compute. Geekbench results show 18290 in OpenCL and 54228 in Vulkan. The 3DMark Steel Nomad DX12 test records 4157. Passmark legacy DX tests show 304 in DX9, 249 in DX11, 121 in DX10, and 93 in DX12. The nearest rivals to the RX 7800 XT in the database are all within a narrow band. The NVIDIA GeForce GTX 1660 averages 11680, which is 0.5% higher than the RX 7800 XT. The AMD Radeon Pro 5500M averages 11528, 0.9% lower. The NVIDIA Tesla K20c averages 11479, 1.3% lower. The AMD Radeon RX 6500 XT averages 11842, 1.8% higher. These deltas indicate the RX 7800 XT's average score sits in a tightly clustered group of older or lower-tier cards, despite its modern architecture and specifications.

The LX 7G100 cannot be ranked against these rivals because no benchmark scores exist for it. The database records zero wins for either part in head-to-head testing. The comparison therefore rests on architectural specifications and the RX 7800 XT's measured performance alone.

Architecture Differences

The two GPUs use different fabrication processes and architectures. The AMD Radeon RX 7800 XT is built on a 5 nm process at TSMC, using the Navi 32 chip with RDNA 3.0 architecture. Its codename is Wheat Nas, and it belongs to the Navi III (RX 7000) generation. The Lisuan Tech LX 7G100 uses a 6 nm process, also at TSMC, with a chip labeled 7G106 and an architecture called TrueGPU. Its generation is listed as 7G100.

Transistor counts differ dramatically. The RX 7800 XT contains 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2 million transistors per square millimeter. The LX 7G100's transistor count and die size are recorded as unknown, so density cannot be calculated. The RX 7800 XT has 3840 shading units, 240 texture mapping units, and 96 raster output units. It also includes 60 ray tracing cores. The LX 7G100 has 6144 shading units, 192 texture mapping units, and 96 raster output units. It has no recorded ray tracing core count.

Clock behavior differs in how it is reported. The RX 7800 XT has a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. The LX 7G100 has no base, boost, or game clock listed in the database. Memory clocks are recorded for both: the RX 7800 XT runs at 2438 MHz with 19.5 Gbps effective data rate, while the LX 7G100 runs at 2250 MHz with 18 Gbps effective.

Memory configurations diverge. The RX 7800 XT has 16 GB of GDDR6 on a 256 bit bus, delivering 624.1 GB/s of bandwidth. The LX 7G100 has 12 GB of GDDR6 on a 192 bit bus, delivering 432.0 GB/s. The RX 7800 XT offers higher capacity and substantially higher bandwidth.

Theoretical throughput figures favor the RX 7800 XT in pixel and texture rates. It delivers 233.3 GPixel/s and 583.2 GTexel/s. The LX 7G100 delivers 192.0 GPixel/s and 384.0 GTexel/s. In FP32 compute, the RX 7800 XT reaches 37.32 TFLOPS with a 1:1 FP16 ratio. The LX 7G100 reaches 24.58 TFLOPS in FP32, but its FP16 output is 49.15 TFLOPS with a 2:1 ratio, meaning it doubles throughput in half precision.

API support is similar but not identical. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RX 7800 XT supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. Display outputs differ: the RX 7800 XT offers 1x HDMI 2.1a and 3x DisplayPort 2.1, while the LX 7G100 offers 4x DisplayPort 1.4a.

Power delivery differs. The RX 7800 XT has a TDP of 263 W, uses 2x 8-pin power connectors, and recommends a 600 W PSU. The LX 7G100 has a TDP of 225 W, uses 1x 8-pin connector, and recommends a 550 W PSU. Physical dimensions also differ. The RX 7800 XT is 267 mm long, 111 mm tall, and 50 mm wide. The LX 7G100 is 294 mm long, 120 mm tall, and 49 mm wide. Both are dual-slot cards and use PCIe 4.0 x16.

The Verdict

The data shows the AMD Radeon RX 7800 XT is the only part in this comparison with recorded performance. Its average benchmark score of 11627 places it at the 51st percentile, and its nearest rivals are all within 1.8% of its average. The Lisuan Tech LX 7G100 has no benchmark scores, no average score, and no rivals listed. Any performance-based recommendation must therefore favor the RX 7800 XT, since its performance is measured and the LX 7G100's is not.

The RX 7800 XT also leads in several specification categories. It has more memory (16 GB versus 12 GB), a wider memory bus (256 bit versus 192 bit), higher memory bandwidth (624.1 GB/s versus 432.0 GB/s), higher pixel rate (233.3 GPixel/s versus 192.0 GPixel/s), higher texture rate (583.2 GTexel/s versus 384.0 GTexel/s), and higher FP32 compute (37.32 TFLOPS versus 24.58 TFLOPS). It includes 60 ray tracing cores, which the LX 7G100 does not list. It has a newer Vulkan version (1.4 versus 1.3) and more modern display outputs (DisplayPort 2.1 versus DisplayPort 1.4a).

The LX 7G100 counters with a higher shading unit count (6144 versus 3840), higher FP16 throughput (49.15 TFLOPS versus 37.32 TFLOPS), lower TDP (225 W versus 263 W), and a single 8-pin power connector instead of two. Its 6 nm process is one node step behind the RX 7800 XT's 5 nm process.

The verdict from the recorded data is clear. The RX 7800 XT is the better-documented, better-performing GPU. The LX 7G100 remains a specification-only entry with no measurable performance data, so it cannot be placed in any performance ranking.

Where Each One Wins

The AMD Radeon RX 7800 XT wins in every performance category where data exists. It has a recorded average benchmark score of 11627 versus no recorded score for the LX 7G100. It delivers higher memory bandwidth (624.1 GB/s versus 432.0 GB/s), higher pixel rate (233.3 GPixel/s versus 192.0 GPixel/s), higher texture rate (583.2 GTexel/s versus 384.0 GTexel/s), and higher FP32 compute (37.32 TFLOPS versus 24.58 TFLOPS). It has more memory (16 GB versus 12 GB), a wider bus (256 bit versus 192 bit), 60 ray tracing cores versus none listed, Vulkan 1.4 versus 1.3, and DisplayPort 2.1 outputs versus DisplayPort 1.4a. It is also built on a smaller 5 nm process versus the LX 7G100's 6 nm process, and it contains 28,100 million transistors on a 346 mm² die, though the LX 7G100's transistor count is unknown.

The Lisuan Tech LX 7G100 wins in a smaller set of specification categories. It has 6144 shading units versus 3840, giving it a raw shader count advantage. Its FP16 throughput of 49.15 TFLOPS exceeds the RX 7800 XT's 37.32 TFLOPS, with a 2:1 FP16 ratio versus a 1:1 ratio. It consumes less power, with a TDP of 225 W versus 263 W, and requires only a single 8-pin power connector compared to the RX 7800 XT's two. Its recommended PSU is 550 W versus 600 W. It also offers four DisplayPort outputs, one more than the RX 7800 XT's three DisplayPort outputs, though at the older 1.4a standard.

Neither GPU wins in head-to-head benchmark testing because no head-to-head results are recorded. The RX 7800 XT's wins are all derived from its measured benchmark scores and its superior memory, pixel, texture, and FP32 specifications. The LX 7G100's wins are limited to shader count, FP16 throughput, and power efficiency metrics.
