AMD Radeon 740M vs Lisuan Tech LX MAX Comparison

The Verdict

The database comparison between the AMD Radeon 740M and the Lisuan Tech LX MAX is defined by two very different design philosophies. The Radeon 740M is an integrated graphics processor built for efficiency and mobility, while the Lisuan Tech LX MAX is a large discrete graphics card built for raw throughput. The recorded data shows the Lisuan Tech LX MAX holds a massive theoretical performance advantage, but it does so at a substantial cost in power and physical size.

The AMD Radeon 740M is the only one of the two with recorded benchmark results. It scores 10,172 in Geekbench OpenCL and 15,568 in Geekbench Vulkan, giving it an average benchmark score of 12,870. This places it at the 53rd percentile of all GPUs in the database, which indicates it sits slightly above the median performer. The Lisuan Tech LX MAX has no recorded benchmark scores, no average score, and no nearest rivals in the database, meaning its performance cannot be verified through direct measurements.

For users who need a functional graphics solution embedded in a processor, the Radeon 740M is the clear choice. It operates at a 45 W TDP, requires no power connectors, and occupies no expansion slot as an integrated graphics processor. The Lisuan Tech LX MAX, by contrast, demands a 225 W TDP, a 550 W suggested power supply, a dual-slot footprint, and a 16-pin power connector. The data shows the Radeon 740M is the only option for compact or power-constrained systems.

For users who prioritize raw compute throughput and are building a desktop with adequate power delivery and chassis space, the Lisuan Tech LX MAX presents a compelling specification sheet. Its 24.58 TFLOPS of FP32 performance dwarfs the Radeon 740M's 2.867 TFLOPS, representing a difference of roughly 8.6 times. However, the absence of any measured benchmark data for the Lisuan Tech LX MAX means these are paper specifications, not verified results.

Where Each One Wins

The Radeon 740M wins in integration and efficiency. It uses the Phoenix2 chip on a 4 nm TSMC process, which allows it to fit into a processor package with a 45 W TDP. Its memory is system shared, meaning it pulls from the host system's RAM, which keeps system complexity low. It supports PCIe 4.0 x8, which is sufficient for an integrated solution. The Radeon 740M also offers a newer Vulkan implementation at version 1.4, compared to the Lisuan Tech LX MAX's Vulkan 1.3.

The Lisuan Tech LX MAX wins in every raw specification category that matters for high-performance workloads. It has 6,144 shading units compared to the Radeon 740M's 256, which is a 24-fold difference. It has 192 texture mapping units against 16, and 96 render output units against 8. Its 12 GB of dedicated GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth, while the Radeon 740M's memory bandwidth is system dependent. The Lisuan Tech LX MAX also has a dedicated 16-pin power connector and a dual-slot cooler, indicating it is designed for sustained heavy loads.

The pixel rate comparison is stark. The Lisuan Tech LX MAX delivers 192.0 GPixel/s, while the Radeon 740M manages 22.40 GPixel/s. Similarly, the texture rate is 384.0 GTexel/s versus 44.80 GTexel/s. In every metric of raw graphics throughput, the Lisuan Tech LX MAX is the dominant part.

Architecture Differences

The two GPUs come from completely different architectural lineages. The AMD Radeon 740M uses the RDNA 3.0 architecture on the Phoenix2 chip, part of the Navi III IGP generation. It is built on a 4 nm process at TSMC and contains 20,900 million transistors on a 137 mm² die, resulting in a transistor density of 152.6 million transistors per square millimeter. It includes 4 ray tracing cores, which the Lisuan Tech LX MAX does not list.

The Lisuan Tech LX MAX uses the TrueGPU architecture on the 7G106 chip, part of the 7G100 generation. It is built on a 6 nm process, also at TSMC, but its transistor count and die size are listed as unknown in the database. The architecture supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, matching the Radeon 740M on those APIs, but its Vulkan support is version 1.3, one version behind.

The memory architecture is fundamentally different. The Radeon 740M uses system shared memory with no dedicated VRAM, making its bandwidth entirely dependent on the host system. The Lisuan Tech LX MAX uses 12 GB of GDDR6 memory on a 192-bit bus, with memory clocked at 2250 MHz or 18 Gbps effective, producing 432.0 GB/s of bandwidth. This dedicated memory arrangement is a major architectural distinction.

The shader configuration also differs significantly. The Radeon 740M has 256 shading units, 16 TMUs, and 8 ROPs. The Lisuan Tech LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs. The FP16 performance ratio differs as well: the Radeon 740M delivers FP16 at a 1:1 ratio with FP32 at 2.867 TFLOPS, while the Lisuan Tech LX MAX delivers FP16 at a 2:1 ratio, reaching 49.15 TFLOPS against its 24.58 TFLOPS FP32.

A: The Radeon 740M is built on a 4 nm TSMC process with 20,900 million transistors on a 137 mm² die. The Lisuan Tech LX MAX is built on a 6 nm TSMC process, but its transistor count and die size are unknown.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two GPUs, and the win counts are zero for both. The Radeon 740M has its own benchmark scores, while the Lisuan Tech LX MAX has none. The comparison therefore relies on the specification sheets and the Radeon 740M's performance context.

The Radeon 740M's average benchmark score of 12,870 places it at the 53rd percentile of all GPUs. Its nearest rivals in the database are all within a fraction of a percent. The AMD FirePro W5100 scores 12,847, just 0.2% behind. The AMD Radeon Pro 455 scores 12,831, 0.3% behind. The NVIDIA GeForce GTX 590 scores 12,830, also 0.3% behind. The AMD Radeon RX 580 scores 12,928, which is 0.4% ahead of the Radeon 740M. This clustering shows the Radeon 740M delivers performance squarely in the middle of a group of older discrete GPUs, despite being an integrated solution.

The Lisuan Tech LX MAX's theoretical specifications suggest it would outperform the Radeon 740M by a wide margin if its real-world performance matches its paper specifications. Its FP32 throughput of 24.58 TFLOPS is roughly 8.6 times the Radeon 740M's 2.867 TFLOPS. Its texture rate of 384.0 GTexel/s is about 8.6 times the 44.80 GTexel/s of the Radeon 740M. Its pixel rate of 192.0 GPixel/s is about 8.6 times the 22.40 GPixel/s of the Radeon 740M. These ratios are consistent because the Lisuan Tech LX MAX has 24 times the shading units, 12 times the TMUs, and 12 times the ROPs, but its clock speeds are not listed in the database, so a direct clock-for-clock comparison is impossible.

The memory bandwidth gap is equally significant. The Lisuan Tech LX MAX delivers 432.0 GB/s from its dedicated GDDR6 memory. The Radeon 740M's bandwidth is system dependent, meaning it can vary based on the host platform's memory configuration. In any scenario, a dedicated 192-bit GDDR6 interface will provide far more bandwidth than shared system memory, which is a structural advantage for the Lisuan Tech LX MAX in memory-heavy workloads.

Specification Differences

The two GPUs differ across nearly every recorded field. The Radeon 740M uses the Phoenix2 chip with RDNA 3.0 architecture on a 4 nm process. The Lisuan Tech LX MAX uses the 7G106 chip with TrueGPU architecture on a 6 nm process. The Radeon 740M has 20,900 million transistors on a 137 mm² die; the Lisuan Tech LX MAX lists both as unknown.

Clock speeds differ in availability. The Radeon 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The Lisuan Tech LX MAX has no base or boost clock listed. Its memory clock is 2250 MHz or 18 Gbps effective, while the Radeon 740M's memory clock is system shared.

The core configuration differs dramatically. The Radeon 740M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The Lisuan Tech LX MAX has 6,144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing cores listed. The Radeon 740M delivers 22.40 GPixel/s, 44.80 GTexel/s, 2.867 TFLOPS FP32, and 2.867 TFLOPS FP16. The Lisuan Tech LX MAX delivers 192.0 GPixel/s, 384.0 GTexel/s, 24.58 TFLOPS FP32, and 49.15 TFLOPS FP16.

Power requirements are opposite ends of the spectrum. The Radeon 740M runs at 45 W with no power connectors and an IGP slot width. The Lisuan Tech LX MAX runs at 225 W with a 16-pin connector, a 550 W suggested power supply, and a dual-slot width. The Radeon 740M uses PCIe 4.0 x8, while the Lisuan Tech LX MAX uses PCIe 4.0 x16. Display outputs are motherboard dependent for the Radeon 740M, while the Lisuan Tech LX MAX has 4x DisplayPort 1.4a.
