AMD Steam Deck OLED GPU vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark scores for these two GPUs. Both entries show an average benchmark score of 0, and the head-to-head benchmark table is empty. Consequently, the comparative analysis must rely entirely on the architectural specifications and derived performance indicators recorded in the database.

The most decisive numerical gap between the two lies in raw compute throughput. The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 performance, while the AMD Steam Deck OLED GPU provides 1.638 TFLOPS. This represents a 15.0x difference in favor of the LX PRO. The gap in FP16 is equally stark: 49.15 TFLOPS versus 3.277 TFLOPS, again a 15.0x advantage for the LX PRO.

Memory bandwidth tells a similar story. The LX PRO achieves 432.0 GB/s across a 192-bit bus, while the Steam Deck OLED GPU manages 176.0 GB/s over a 128-bit bus. The LX PRO delivers 2.45x the bandwidth. Its memory operates at 18 Gbps effective, compared to 11 Gbps effective for the AMD part.

Pixel and texture throughput follow the same pattern. The LX PRO renders at 192.0 GPixel/s, which is 7.5x the 25.60 GPixel/s of the Steam Deck OLED GPU. Texture fill rates stand at 384.0 GTexel/s for the LX PRO versus 51.20 GTexel/s for the AMD chip, a 7.5x margin.

The Steam Deck OLED GPU counters with a substantially lower power envelope. Its TDP is recorded at 15 W, while the LX PRO draws 225 W. This means the AMD part operates at 6.7% of the power consumption of the LX PRO. The efficiency ratio, measured as FP32 TFLOPS per watt, favors the Steam Deck OLED GPU: 0.109 TFLOPS/W versus 0.109 TFLOPS/W for the LX PRO. Both parts show identical efficiency per watt, a notable coincidence given their different architectures, though the LX PRO's absolute throughput remains far higher.

The LX PRO also holds the advantage in shader resources. It contains 6144 shading units, 192 texture mapping units, and 96 render output units. The Steam Deck OLED GPU has 512 shading units, 32 TMUs, and 16 ROPs. These figures indicate the LX PRO is configured for high-resolution rendering, while the AMD part is optimized for constrained power budgets.

Both GPUs share the same percentile ranking against all GPUs in the database at 50. This indicates that, despite the massive specification differences, neither part is positioned as an outlier in the overall distribution of recorded GPUs. The Steam Deck OLED GPU achieves this with a minimal resource footprint, while the LX PRO does so with substantial hardware.

Architecture Differences

The two GPUs are built on entirely different architectural foundations. The AMD Steam Deck OLED GPU uses the RDNA 2.0 architecture on a chip codenamed Sephiroth. It belongs to the Console GPU (Valve) generation. The Lisuan Tech LX PRO uses a proprietary TrueGPU architecture on a chip designated 7G105, part of the 7G100 generation.

Both are fabricated on a 6 nm process at TSMC. The AMD part integrates 2,400 million transistors on a die measuring 131 mm², resulting in a transistor density of 18.3M per mm². The LX PRO's transistor count and die size are recorded as unknown, so no density comparison is possible.

Ray tracing support differs. The Steam Deck OLED GPU includes 8 dedicated ray tracing cores. The LX PRO lists no ray tracing cores in its specification. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, so API-level feature parity exists despite the hardware divergence.

Memory technology separates the two clearly. The AMD part uses 16 GB of LPDDR5 memory, a low-power standard suited to portable devices. The LX PRO uses 24 GB of GDDR6 memory, a high-bandwidth standard for discrete graphics cards. The capacity difference is 8 GB in favor of the LX PRO, but the bandwidth difference is more consequential for rendering workloads.

Clock behavior also diverges. The Steam Deck OLED GPU has a base clock of 1000 MHz and a boost clock of 1600 MHz. The LX PRO has no base or boost clock recorded in the database. Its memory clock is listed at 2250 MHz with 18 Gbps effective throughput, whereas the AMD part's memory clock is 1375 MHz with 11 Gbps effective.

The physical form factors could not be more different. The Steam Deck OLED GPU is an integrated console component with a single USB Type-C display output. The LX PRO is a dual-slot discrete card using a PCIe 4.0 x16 interface, one 16-pin power connector, a 550 W suggested PSU, and four DisplayPort 1.4a outputs. The AMD part measures 298 mm by 117 mm by 49 mm, while the LX PRO measures 248 mm by 118 mm by 48 mm. Despite the LX PRO being a discrete card, it is shorter in length than the console-integrated AMD part.

Where Each One Wins

The Lisuan Tech LX PRO wins decisively in every raw performance category recorded. Its FP32 throughput of 24.58 TFLOPS positions it for demanding compute workloads, high-resolution gaming, and professional rendering tasks. The 24 GB memory capacity, combined with 432.0 GB/s bandwidth, supports large assets and texture-heavy scenes. The 192-bit bus width and 96 ROPs enable high fill rates at 192.0 GPixel/s, which matters for 4K and multi-monitor configurations. The four DisplayPort 1.4a outputs allow multi-display setups directly from the card.

The AMD Steam Deck OLED GPU wins in power efficiency and portability. Its 15 W TDP is 15x lower than the LX PRO's 225 W. This makes it suitable for battery-powered handheld systems where thermal and electrical constraints dominate. The integrated nature of the part, evident from its single USB Type-C output and console generation classification, means it occupies no expansion slot and requires no external power connector. Its 16 GB of LPDDR5 memory is generous for its power class and provides unified memory access typical of console designs.

The streaming and low-power gaming segment favors the AMD part. The LX PRO's 550 W suggested PSU and 16-pin connector demand a desktop power supply and cooling solution. The Steam Deck OLED GPU requires none of that infrastructure. For users building a compact, low-power system, the AMD part is the only viable option between the two.

The LX PRO's 6144 shading units versus 512 for the AMD part indicates a 12.0x advantage in parallel compute lanes. This translates directly to workloads that scale with shader count, such as physics simulation, machine learning inference, and video encoding. The AMD part's 8 ray tracing cores provide hardware-accelerated ray tracing, a feature the LX PRO lacks entirely.

The Verdict

The data supports a clear split by use case. For any workload where absolute performance is the priority, the Lisuan Tech LX PRO is the superior choice. Its 24.58 TFLOPS FP32 output, 432.0 GB/s bandwidth, and 24 GB memory capacity place it in a different performance class entirely. The 15.0x compute advantage and 7.5x pixel rate advantage leave no ambiguity in raw capability comparisons.

For power-constrained environments, the AMD Steam Deck OLED GPU is the logical selection. Its 15 W TDP enables operation in handheld consoles and compact systems where the LX PRO's 225 W requirement and 550 W suggested PSU would be impossible to accommodate. The AMD part's 16 GB memory and 176.0 GB/s bandwidth remain respectable within its power envelope.

The identical 50th percentile ranking for both GPUs in the database suggests that neither is an extreme outlier in the broader GPU landscape. The LX PRO achieves this ranking with high absolute performance, while the AMD part achieves it with minimal power draw and modest resources.

Buyers requiring multi-display output, high-bandwidth memory, or massive compute throughput should select the LX PRO. Buyers requiring portability, low power draw, or integrated operation should select the Steam Deck OLED GPU. The two parts do not compete in the same market segment; their specifications place them at opposite ends of the performance-per-watt spectrum.
