Head-to-Head Benchmarks

No direct head-to-head benchmark results are recorded in the database for these two GPUs. The AMD Radeon 740M has two recorded benchmarks: 10172 in Geekbench OpenCL and 15568 in Geekbench Vulkan. Its average benchmark score is 12870, placing it in the 53rd percentile of all GPUs. The Lisuan Tech LX ULTRA has no recorded benchmarks, an average benchmark score of 0, and a percentile rank of 50.

The Radeon 740M nearest rivals provide context for its measured performance. It sits 0.2% above the AMD FirePro W5100 (average score 12847), 0.3% above the AMD Radeon Pro 455 (12831), and 0.3% above the NVIDIA GeForce GTX 590 (12830). It is 0.4% below the AMD Radeon RX 580 (12928). These narrow margins indicate the Radeon 740M performs in a tight cluster around the 12830 to 12928 range.

Since the LX ULTRA lacks benchmark entries, the comparison between the two relies on specification deltas rather than measured scores. The LX ULTRA FP32 output is approximately 8.6 times higher than the Radeon 740M, and its texture rate is approximately 8.6 times higher as well. The LX ULTRA pixel rate is approximately 8.6 times higher, and its memory bandwidth is fixed at 432.0 GB/s, whereas the Radeon 740M bandwidth is system dependent.

Where Each One Wins

The AMD Radeon 740M wins in efficiency-oriented scenarios. Its 45 W TDP, lack of power connectors, and IGP slot width mean it can operate in systems without discrete power delivery. It has recorded benchmark scores, allowing direct assessment of its performance relative to other GPUs. Its 53rd percentile ranking, based on an average score of 12870, shows it performs comparably to discrete GPUs from prior generations, such as the FirePro W5100 and Radeon Pro 455. The Radeon 740M also supports Vulkan 1.4, a newer API version than the LX ULTRA.

The Lisuan Tech LX ULTRA wins in raw performance and capacity. Its 24.58 TFLOPS FP32, 49.15 TFLOPS FP16, 24 GB GDDR6 memory, and 432.0 GB/s bandwidth position it for compute-heavy tasks. Its 6144 shading units, 192 TMUs, and 96 ROPs give it a structural advantage in parallel workloads. The 4x DisplayPort 1.4a outputs support multi-display configurations, and the PCIe 4.0 x16 interface provides double the lane width of the Radeon 740M.

The LX ULTRA also wins on physical configurability. It is a dual-slot card with defined dimensions, a 16-pin power connector, and a 550 W suggested power supply, meaning it is designed for installation in a desktop chassis with adequate cooling and power headroom. The Radeon 740M, as an IGP, depends on the motherboard for display output and memory, limiting its standalone capabilities.

For users with workloads that fit within shared memory and modest compute demands, the Radeon 740M is the recorded option with verified benchmark data. For users prioritizing dedicated memory capacity, bandwidth, and compute throughput, the LX ULTRA is the specification leader, albeit without measured benchmark confirmation in the database.
