AMD Radeon RX 6450M vs Lisuan Tech LX MAX Comparison

The Verdict

The recorded data presents two fundamentally different products that share almost nothing except a 6 nm TSMC process node. The AMD Radeon RX 6450M is a low-power mobile graphics solution designed for thin-and-light laptops, drawing 50 W and using an IGP slot width. The Lisuan Tech LX MAX is a dual-slot desktop board with a 225 W TDP, a 1x 16-pin power connector, and a suggested 550 W PSU. The performance gap between them is substantial across nearly every measurable metric.

The Lisuan Tech LX MAX clearly dominates in raw compute throughput. Its FP32 rating of 24.58 TFLOPS is roughly 6.5 times the RX 6450M's 3.779 TFLOPS. Texture rate favors the LX MAX at 384.0 GTexel/s versus 118.1 GTexel/s, a 3.25x advantage. Pixel rate also favors the LX MAX at 192.0 GPixel/s versus 78.72 GPixel/s. Memory bandwidth is even more lopsided: 432.0 GB/s versus 128.0 GB/s, a 3.375x difference.

For users seeking maximum performance in desktop workloads, the data unambiguously points to the Lisuan Tech LX MAX. Its 12 GB memory capacity and 192-bit bus width provide a much larger working set for rendering, compute, and high-resolution textures. The RX 6450M's 4 GB memory and 64-bit bus limit it to lighter tasks.

The AMD part makes sense only in the mobile context. Its 50 W TDP, IGP slot width, and absence of power connectors indicate a chip designed to fit into compact notebooks. The LX MAX, with its 248 mm length and dual-slot design, requires a full desktop chassis with adequate cooling and power delivery. There is no scenario in which the RX 6450M competes with the LX MAX on performance, nor is there a scenario in which the LX MAX fits into the RX 6450M's intended form factor.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The AMD Radeon RX 6450M uses the Navi 24 chip built on RDNA 2.0 architecture, part of the Navi Mobile (RX 6000M) generation. The Lisuan Tech LX MAX uses a chip designated 7G106 with an architecture called TrueGPU, belonging to the 7G100 generation. Neither shares a common design philosophy beyond the 6 nm TSMC fabrication process.

The RX 6450M packs 5,400 million transistors into a 107 mm² die, yielding a transistor density of 50.5M per mm². The LX MAX's transistor count and die size are listed as unknown, so direct density comparisons are impossible from the recorded data.

Compute unit organization differs sharply. The RX 6450M has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The LX MAX has 6,144 shading units (8x more), 192 TMUs (4x more), and 96 ROPs (3x more). Notably, the LX MAX lists no ray tracing cores, while the AMD part explicitly includes 12 RT cores. The presence of RT cores in the RX 6450M suggests hardware-accelerated ray tracing support, whereas the LX MAX's architecture may handle such workloads differently or not at all.

Memory subsystems diverge completely. The RX 6450M uses 4 GB GDDR6 on a 64-bit bus with 128.0 GB/s bandwidth and 16 Gbps effective memory speed. The LX MAX uses 12 GB GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth and 18 Gbps effective memory speed. The LX MAX's bus width is triple that of the AMD part, and its memory clock is higher.

Clock behavior also differs. The RX 6450M has documented base (2000 MHz), boost (2460 MHz), and game (2220 MHz) clocks. The LX MAX lists no base, boost, or game clocks at all, only a memory clock of 2250 MHz (18 Gbps effective). This absence of clock data makes direct frequency comparisons impossible.

API support shows minor differences. Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD part supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. Both list the same DirectX feature level, indicating parity in modern graphics API capabilities.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries for these two GPUs, and both have an average benchmark score of 0 with no individual benchmark results. The wins count stands at 0 for each product. However, the specification-derived rates provide a clear quantitative comparison.

The most significant performance indicator is FP32 throughput. The LX MAX's 24.58 TFLOPS is 6.51 times the RX 6450M's 3.779 TFLOPS. In FP16, the LX MAX's 49.15 TFLOPS is 6.50 times the RX 6450M's 7.557 TFLOPS. These ratios confirm that the LX MAX delivers consistently higher compute throughput across both precision formats.

Texture fill rate shows a 3.25x advantage for the LX MAX (384.0 GTexel/s versus 118.1 GTexel/s). Pixel fill rate shows a 2.44x advantage (192.0 GPixel/s versus 78.72 GPixel/s). These differences matter for rasterization-heavy workloads, where texture and pixel throughput directly impact frame rates.

Memory bandwidth is the largest relative gap: the LX MAX's 432.0 GB/s is 3.375 times the RX 6450M's 128.0 GB/s. With 12 GB capacity versus 4 GB, the LX MAX can hold larger textures, geometry buffers, and compute working sets without spilling to system memory.

The RX 6450M holds one advantage in the recorded data: its boost clock of 2460 MHz is higher than any clock recorded for the LX MAX, which lists none. The AMD part also supports Vulkan 1.4 versus the LX MAX's Vulkan 1.3, a minor API revision difference.

Where Each One Wins

The Lisuan Tech LX MAX wins decisively in every raw performance category recorded. Its FP32 and FP16 compute rates are over 6x higher, its texture rate is over 3x higher, its pixel rate is over 2x higher, and its memory bandwidth is over 3x higher. The 12 GB memory capacity and 192-bit bus make it suitable for large-scale rendering, high-resolution texture workloads, and compute applications that require substantial memory residency. The PCIe 4.0 x16 interface provides double the lane width of the RX 6450M's PCIe 4.0 x4, which benefits data transfer between CPU and GPU. The 4x DisplayPort 1.4a outputs support multi-monitor desktop configurations. The 225 W TDP and dual-slot cooling design indicate sustained performance capability under heavy load.

The AMD Radeon RX 6450M wins in the mobile and efficiency domain. Its 50 W TDP is one-quarter of the LX MAX's 225 W. The IGP slot width and absence of power connectors mean it can be integrated into compact notebook designs without additional power cabling. The 107 mm² die size and 5,400 million transistor count on a 6 nm process show a compact, power-conscious design. The 12 ray tracing cores provide dedicated hardware for ray-traced effects, a feature the LX MAX does not list. Its Vulkan 1.4 support is one revision newer than the LX MAX's Vulkan 1.3. For portable systems where power draw and physical footprint matter more than raw throughput, the RX 6450M is the only viable choice between these two.

The data shows two products serving separate markets with no overlap. The LX MAX occupies the high-performance desktop segment, while the RX 6450M occupies the mobile segment. Neither can substitute for the other. Users who need maximum compute and memory bandwidth must choose the LX MAX. Users who need an integrated, low-power solution for a portable device must choose the RX 6450M. The benchmark database contains no evidence that either product attempts to serve the other's use case.
