AMD Radeon RX 6450M vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database has no recorded head-to-head benchmark entries for the AMD Radeon RX 6450M and the Lisuan Tech LX ULTRA. Both GPUs return an average benchmark score of 0, and neither is listed with nearest rival data. The absence of measured performance data means direct frame-rate comparisons cannot be drawn from recorded measurements. What can be analyzed is the theoretical compute ceiling each part presents, derived from their respective shading unit counts, clock rates, and memory configurations.

The Lisuan Tech LX ULTRA projects a peak FP32 throughput of 24.58 TFLOPS, while the AMD Radeon RX 6450M projects 3.779 TFLOPS. That is a 6.5x gap in raw single-precision compute. The LX ULTRA also reports 49.15 TFLOPS for FP16 (2:1 ratio), versus 7.557 TFLOPS for the RX 6450M. Texture rate differs similarly: 384.0 GTexel/s for the LX ULTRA versus 118.1 GTexel/s for the RX 6450M. Pixel throughput shows 192.0 GPixel/s against 78.72 GPixel/s.

Memory bandwidth heavily favors the LX ULTRA at 432.0 GB/s, more than triple the RX 6450M’s 128.0 GB/s. The LX ULTRA carries 24 GB of GDDR6 on a 192-bit bus, while the RX 6450M carries 4 GB of GDDR6 on a 64-bit bus. Effective memory speed for the LX ULTRA is 18 Gbps; the RX 6450M runs at 16 Gbps effective. These numbers indicate the LX ULTRA is built for sustained high-resolution workloads, whereas the RX 6450M is positioned at the entry tier of the mobile Radeon stack.

Both parts fall at the 50th percentile across all GPUs in the database. The percentile figure is identical, which suggests the database ranks them in the same broad performance tier despite the large compute disparity. That placement is likely a consequence of the absence of benchmark entries rather than a reflection of real-world equivalence.

Architecture Differences

The RX 6450M uses the Navi 24 chip built on the RDNA 2.0 architecture, part of the Navi Mobile (RX 6000M) generation. The LX ULTRA uses a chip designated 7G105 under an architecture labeled TrueGPU, belonging to the 7G100 generation. Both are fabricated on a 6 nm process at TSMC, but that is where the manufacturing similarities end.

The RX 6450M integrates 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5M per mm². The LX ULTRA lists transistor count and die size as unknown, so no density figure can be derived from the records. The RX 6450M has 768 shading units, 48 texture mapping units, and 32 ROPs. The LX ULTRA scales to 6,144 shading units, 192 TMUs, and 96 ROPs. That is an 8x increase in shader count, a 4x increase in TMUs, and a 3x increase in ROPs.

Ray tracing hardware is present only on the RX 6450M, which includes 12 RT cores. The LX ULTRA lists no RT core count in the database. The RX 6450M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The LX ULTRA supports DirectX 12 Ultimate (12_2) and OpenGL 4.6, but its Vulkan support is version 1.3, one revision behind the AMD part.

Power delivery and physical design diverge sharply. The RX 6450M draws 50 W TDP, uses no power connectors, and is classified as an integrated graphics processor (IGP) with a slot width of "IGP". The LX ULTRA draws 225 W TDP, requires a single 16-pin connector, suggests a 550 W power supply, and is a dual-slot card measuring 268 mm in length, 112 mm in height, and 40 mm in width. The RX 6450M has no listed dimensions. The LX ULTRA exposes 4x DisplayPort 1.4a outputs, while the RX 6450M’s display outputs are described as portable device dependent.

Where Each One Wins

The RX 6450M wins on efficiency and integration. Its 50 W TDP allows deployment in compact portable systems where discrete power delivery is unavailable. It has no external power connector requirement and is classified as an IGP, meaning it can slot into thin designs. The RX 6450M also carries dedicated ray tracing cores, a feature the LX ULTRA does not list. Its smaller 107 mm² die and 6 nm process translate into a lower physical footprint, which suits space-constrained chassis.

The LX ULTRA wins on raw throughput across every measured compute metric. Its FP32 output of 24.58 TFLOPS dwarfs the RX 6450M’s 3.779 TFLOPS. The 24 GB memory pool is six times larger than the RX 6450M’s 4 GB. The 192-bit memory bus and 432.0 GB/s bandwidth indicate the LX ULTRA is designed for data-heavy rendering tasks, large texture sets, and high-resolution framebuffers. Its PCIe 4.0 x16 interface provides more host bandwidth than the RX 6450M’s PCIe 4.0 x4 connection.

The LX ULTRA also offers more display outputs at 4x DisplayPort 1.4a, which supports multi-monitor configurations directly. The RX 6450M’s output count depends on the host portable device. The LX ULTRA’s 192 TMUs and 96 ROPs give it a structural advantage in texture-heavy and fill-rate-bound scenes. The RX 6450M’s 48 TMUs and 32 ROPs are a fraction of those totals.

The Verdict

The recorded data points to two GPUs aimed at different segments. The AMD Radeon RX 6450M is a low-power integrated part with 50 W TDP, no external power connectors, and an IGP slot classification. Its 4 GB memory pool and 64-bit bus align with entry-level portable use. It carries 12 RT cores and Vulkan 1.4 support, which are absent or lower on the LX ULTRA.

The Lisuan Tech LX ULTRA is a large dual-slot discrete card with a 225 W TDP, a 16-pin power connector, and a 550 W suggested power supply. Its 24 GB memory, 192-bit bus, and 432.0 GB/s bandwidth target memory-intensive workloads. Its FP32 throughput of 24.58 TFLOPS is over six times that of the RX 6450M. The LX ULTRA’s PCIe 4.0 x16 interface and 4x DisplayPort 1.4a outputs reinforce a desktop-oriented design.

The RX 6450M fits systems where power draw and physical space are constrained, and where ray tracing support matters. The LX ULTRA fits configurations that prioritize compute throughput, memory capacity, and bandwidth over efficiency. Neither part has benchmark scores recorded in the database, so the verdict rests entirely on specification analysis. The data indicates the LX ULTRA is the stronger performer on paper for raw rendering work, while the RX 6450M is the more portable and power-efficient option.
