AMD Radeon RX 6450M vs Lisuan Tech LX PRO Comparison

Where Each One Wins

The recorded data splits these two GPUs into entirely different usage classes. The AMD Radeon RX 6450M is a low-power integrated-class part, while the Lisuan Tech LX PRO is a high-performance dual-slot desktop card. The benchmark wins are one-sided: the Lisuan Tech LX PRO dominates every compute and memory metric, while the AMD Radeon RX 6450M wins only on power efficiency and physical integration.

The AMD Radeon RX 6450M carries a 50 W TDP and an IGP slot width with no power connectors, making it suitable for thin-and-light portable systems. Its architecture is built around a 64-bit memory bus with 4 GB GDDR6, which limits its bandwidth to 128.0 GB/s. The benchmark results show this part is oriented toward basic rendering and low-resolution gaming, not heavy compute workloads.

The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 performance, which is over six times the 3.779 TFLOPS of the AMD part. Its 24 GB GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, more than three times the AMD chip. The LX PRO also outputs 192.0 GPixel/s and 384.0 GTexel/s, versus 78.72 GPixel/s and 118.1 GTexel/s for the RX 6450M. These numbers indicate that the Lisuan part wins every measurable performance category.

The AMD RX 6450M has the advantage in power draw: 50 W versus 225 W for the LX PRO. It also requires no external power connectors, while the LX PRO needs a single 16-pin connector and a 550 W suggested power supply. For systems where power delivery is constrained, the AMD part is the only viable option. For raw throughput, the Lisuan Tech LX PRO is the clear winner across the board.

Architecture Differences

The two GPUs share a 6 nm process node from TSMC, but their architectural designs diverge sharply. The AMD Radeon RX 6450M uses the Navi 24 chip with RDNA 2.0 architecture, part of the Navi Mobile generation within the Radeon RX 6000 series. It contains 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million per square millimeter. The Lisuan Tech LX PRO uses the 7G105 chip with TrueGPU architecture from the 7G100 generation. Its transistor count and die size are unknown, and no density figure is recorded.

The AMD chip deploys 768 shading units, 48 texture mapping units, and 32 render output units. It also has 12 dedicated ray tracing cores. The Lisuan Tech LX PRO is configured with 6144 shading units, 192 TMUs, and 96 ROPs, which is eight times the shading units and four times the TMUs and ROPs of the AMD part. The LX PRO does not list any ray tracing cores, so its ray tracing capabilities are unrecorded in the database.

Memory architecture also differs substantially. The RX 6450M has 4 GB GDDR6 on a 64-bit bus running at 16 Gbps effective, producing 128.0 GB/s. The LX PRO has 24 GB GDDR6 on a 192-bit bus at 18 Gbps effective, producing 432.0 GB/s. The bus width difference explains the bandwidth gap: the LX PRO has three times the bus width and slightly higher memory clock speed.

Clock behavior also separates the two. The AMD part has recorded base, boost, and game clocks of 2000 MHz, 2460 MHz, and 2220 MHz respectively. The Lisuan Tech LX PRO has no recorded base, boost, or game clocks; only its memory clock of 2250 MHz (18 Gbps effective) is documented. This means the LX PRO's core clock speeds are not available in the database, so comparisons must rely on the aggregate throughput figures.

Interface and output specifications differ as well. The AMD RX 6450M connects via PCIe 4.0 x4 and has display outputs described as "Portable Device Dependent." The Lisuan Tech LX PRO uses PCIe 4.0 x16 and provides four DisplayPort 1.4a outputs. The LX PRO is a dual-slot card measuring 248 mm in length, 118 mm in height, and 48 mm in width, while the AMD part has no recorded dimensions and is classified as IGP.

Head-to-Head Benchmarks

The benchmark data shows no direct head-to-head matchups, but the recorded specification numbers allow for precise quantitative comparisons. The largest single-category win for the Lisuan Tech LX PRO is in shading units: 6144 versus 768, a factor of eight. This translates directly to the FP32 throughput gap. The LX PRO delivers 24.58 TFLOPS, which is 20.80 TFLOPS higher than the RX 6450M's 3.779 TFLOPS, or roughly 6.5 times more compute capacity.

The memory bandwidth comparison shows a 304.0 GB/s advantage for the LX PRO. Its 432.0 GB/s is 3.375 times the 128.0 GB/s of the RX 6450M. Memory capacity is even more lopsided: 24 GB versus 4 GB, a sixfold difference. The LX PRO also wins on texture rate with 384.0 GTexel/s versus 118.1 GTexel/s, a 265.9 GTexel/s gap. The pixel rate difference is 113.28 GPixel/s in favor of the LX PRO (192.0 versus 78.72).

The AMD Radeon RX 6450M wins on power efficiency. Its 50 W TDP is 175 W lower than the LX PRO's 225 W. The AMD part also has a higher boost clock of 2460 MHz, though the LX PRO has no recorded boost clock to compare directly. The AMD chip's game clock of 2220 MHz and base clock of 2000 MHz are recorded, while the LX PRO's clocks are absent from the data.

The FP16 comparison shows the same proportional relationship as FP32. The LX PRO outputs 49.15 TFLOPS (2:1) versus 7.557 TFLOPS (2:1) for the RX 6450M, giving the LX PRO a 41.59 TFLOPS advantage. Both parts support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The AMD part supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3, a minor API version difference in favor of AMD.

The Lisuan Tech LX PRO was released later, dated 2026-03-16, while the AMD RX 6450M is dated 2023-01-03. Both parts are currently marked as Active production status. The AMD part has a listed predecessor (Polaris Mobile) and no successor, while the LX PRO has neither predecessor nor successor recorded.

The Verdict

The data indicates a complete performance separation between these two products. The Lisuan Tech LX PRO is the superior choice for any workload that depends on compute throughput, memory capacity, or memory bandwidth. Its 24.58 TFLOPS FP32, 24 GB GDDR6, and 432.0 GB/s bandwidth place it in a performance class that the AMD RX 6450M cannot approach. The LX PRO also offers 6144 shading units, 192 TMUs, and 96 ROPs, which are eight times, four times, and three times the AMD part's respective counts.

The AMD Radeon RX 6450M is the appropriate choice only for systems with strict power or space constraints. Its 50 W TDP and IGP form factor allow integration into portable devices where the 225 W dual-slot LX PRO cannot fit. The AMD part also carries 12 ray tracing cores, which the LX PRO does not list, and supports Vulkan 1.4 versus 1.3 for the LX PRO. These advantages matter only in niche scenarios: ray-traced workloads on low-power mobile platforms, or API compatibility with the newest Vulkan release.

For desktop systems with adequate power delivery and chassis space, the Lisuan Tech LX PRO is the definitive winner. Its physical dimensions (248 mm length, 118 mm height, 48 mm width) and dual-slot design are standard for high-performance cards, and its 1x 16-pin power connector with 550 W suggested PSU is consistent with its 225 W TDP. The AMD part's 4 GB memory and 64-bit bus would bottleneck any serious compute task, while the LX PRO's 24 GB and 192-bit bus provide headroom for large datasets and high-resolution textures.

The release dates show a generational gap: the AMD part arrived on 2023-01-03, while the LX PRO is dated 2026-03-16. The newer part delivers substantially higher specifications across every performance metric. Users selecting between these two should base the decision on the physical constraints of the target system: mobile or low-power integration points to the AMD RX 6450M, while any performance-oriented desktop build favors the Lisuan Tech LX PRO.
