Architecture Differences

The AMD Radeon 740M and the Lisuan Tech LX 7G100 represent fundamentally different design philosophies. The Radeon 740M is an integrated graphics processor built on the Phoenix2 chip using RDNA 3.0 architecture, part of the Navi III IGP (Phoenix) generation. It is fabricated on a 4 nm process at TSMC, with a die size of 137 mm² and 20,900 million transistors, resulting in a transistor density of 152.6 million per mm². The LX 7G100, in contrast, is a discrete dual-slot card built on the 7G106 chip using an architecture labeled TrueGPU, from the 7G100 generation. It uses a 6 nm TSMC process, though its transistor count and die size are listed as unknown in the database.

The compute resources diverge sharply. The Radeon 740M contains 256 shading units, 16 texture mapping units, and 8 raster output pipelines. It also includes 4 ray tracing cores. The LX 7G100 scales this up considerably with 6,144 shading units, 192 TMUs, and 96 ROPs. The database does not list ray tracing cores for the LX 7G100.

Memory architecture is another major divider. The Radeon 740M uses system-shared memory, with its type, bus width, and size all dependent on the host system. Its memory bandwidth is listed as system dependent. The LX 7G100 has a dedicated 12 GB GDDR6 frame buffer on a 192-bit bus, delivering a fixed 432.0 GB/s of bandwidth and running at 2250 MHz (18 Gbps effective).

Clock behavior also differs. The Radeon 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The LX 7G100 has no base or boost clock listed in the database. Pixel and texture throughput reflect the architectural gap: the LX 7G100 reaches 192.0 GPixel/s and 384.0 GTexel/s, while the Radeon 740M reaches 22.40 GPixel/s and 44.80 GTexel/s.

The LX 7G100 uses a PCIe 4.0 x16 interface, double the lane count of the Radeon 740M's PCIe 4.0 x8 connection. The LX 7G100 is a dual-slot card measuring 294 mm in length, 120 mm in height, and 49 mm in width, with four DisplayPort 1.4a outputs. The Radeon 740M is an IGP with motherboard-dependent display outputs. Power delivery reflects this split: the integrated part draws 45 W with no connectors, while the discrete card draws 225 W through a single 8-pin connector.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon 740M and the Lisuan Tech LX 7G100. The head-to-head array is empty, and the win counts for both sides are zero. This means any direct comparison must rely on the individual recorded results and specification data available for each part.

The Radeon 740M has measurable results in two tests. Its Geekbench OpenCL score is 10,172, and its Geekbench Vulkan score is 15,568. Its average benchmark score across these entries is 12,870. The LX 7G100 has no recorded benchmark scores at all, so the database assigns it an average benchmark score of 0. This absence of data prevents a direct numerical comparison of real-world application performance.

What can be compared is the theoretical compute throughput. The LX 7G100 delivers 24.58 TFLOPS of FP32 performance, which is roughly 8.6 times the 2.867 TFLOPS of the Radeon 740M. In FP16, the LX 7G100 reaches 49.15 TFLOPS with a 2:1 ratio, while the Radeon 740M achieves 2.867 TFLOPS at a 1:1 ratio. The LX 7G100 also leads in pixel rate (192.0 GPixel/s versus 22.40 GPixel/s) and texture rate (384.0 GTexel/s versus 44.80 GTexel/s).

Memory bandwidth favors the discrete card by a wide margin. The LX 7G100's 432.0 GB/s dedicated bandwidth stands against the Radeon 740M's system-dependent shared memory. For workloads that are bandwidth sensitive, such as high-resolution texturing or large data transfers, the LX 7G100 has a structural advantage that the Radeon 740M cannot offset with its shared-memory design.

The Radeon 740M does hold advantages in specific areas. Its Vulkan 1.4 support is a newer API revision than the LX 7G100's Vulkan 1.3. Its 4 nm process node is smaller than the 6 nm node used by the LX 7G100, which contributes to its far lower 45 W TDP. The Radeon 740M also has 4 ray tracing cores, while the LX 7G100 lists none in the database.

For context, the Radeon 740M's nearest rivals in the database are all within a narrow band. The AMD Radeon RX 580 averages 12,928 points, 0.4% higher. The AMD FirePro W5100 averages 12,847 points, 0.2% lower. The AMD Radeon Pro 455 averages 12,831 points, 0.3% lower. The NVIDIA GeForce GTX 590 averages 12,830 points, 0.3% lower. This clustering indicates the Radeon 740M's measured performance sits in a stable, well-populated region of the database. The LX 7G100 has no nearest rivals listed, consistent with its lack of benchmark data.

The Verdict

The data presents a clear split between measured performance and theoretical capability. The AMD Radeon 740M is the only one of the two with recorded benchmark scores. Its average of 12,870 points places it at the 53rd percentile, with all four nearest rivals within a 0.4% margin. For applications that rely on the Geekbench OpenCL and Vulkan workloads recorded in the database, the Radeon 740M has demonstrable, verified results.

The Lisuan Tech LX 7G100 has no benchmark entries, an average score of 0, and a 50th percentile ranking by default. On paper, its specifications are substantially higher: 24.58 TFLOPS FP32, 432.0 GB/s of dedicated bandwidth, and 6,144 shading units. These figures indicate a much larger compute and memory resource pool than the Radeon 740M. However, the database contains no evidence that this theoretical capacity translates into measured application performance.

The choice depends on whether the user values verified results or raw specification headroom. The Radeon 740M suits systems where low power draw (45 W), an integrated form factor, and a proven benchmark profile matter. Its 4 nm process, ray tracing cores, and Vulkan 1.4 support are concrete advantages. The LX 7G100 suits scenarios where the workload demands the full resources of a discrete card: 12 GB of dedicated GDDR6, a 192-bit bus, and roughly 8.6 times the FP32 throughput. Its 225 W power draw, dual-slot footprint, and single 8-pin connector are the costs of that capability.

Without benchmark data for the LX 7G100, the database cannot confirm whether its architectural advantages deliver proportionate real-world gains. The Radeon 740M's scores are recorded and its rival positioning is tight; the LX 7G100's performance remains unmeasured. Users requiring immediate, database-verified performance have one option. Users willing to accept unverified specification-based potential have the other.
