Intel Iris Xe Graphics 80EU Mobile vs Lisuan Tech LX PRO Comparison

Head-to-Head Benchmarks

The database records no direct benchmark scores for either the Intel Iris Xe Graphics 80EU Mobile or the Lisuan Tech LX PRO. Both entries show an average benchmark score of zero, and the head-to-head benchmark table is empty. The percentile rank for both GPUs sits at the 50th percentile against all GPUs in the database, meaning neither has a recorded performance advantage over the other in measured workloads. Without direct numeric comparisons, the raw compute specifications serve as the only quantifiable basis for differentiation.

The most striking contrast appears in raw throughput figures. The Lisuan Tech LX PRO delivers 24.58 TFLOPS of FP32 compute, which is 13.2 times higher than the Intel Iris Xe Graphics 80EU Mobile's 1.856 TFLOPS. In FP16 workloads, the LX PRO reaches 49.15 TFLOPS versus the Iris Xe's 3.712 TFLOPS, a 13.2-fold gap as well. Pixel fill rates show a similar pattern: the LX PRO renders 192.0 GPixel/s while the Iris Xe manages 29.00 GPixel/s, a 6.6x difference. Texture fill rates follow with 384.0 GTexel/s on the LX PRO versus 58.00 GTexel/s on the Iris Xe, again a 6.6x margin.

These figures indicate that in any compute-bound or fill-rate-bound scenario, the Lisuan Tech LX PRO holds an overwhelming advantage. The Iris Xe's only numerical lead appears in its lower memory latency characteristics, as it uses system-shared memory with bandwidth described as "System Dependent," whereas the LX PRO uses dedicated GDDR6 at 432.0 GB/s. The shared-memory approach on the Iris Xe can reduce copy overhead in integrated scenarios, but the database does not provide measured latency values to confirm this advantage.

Architecture Differences

The two GPUs come from entirely different architectural lineages. The Intel Iris Xe Graphics 80EU Mobile is built on Raptor Lake silicon using Intel's Generation 12.2 architecture, also classified under the HD Graphics-M (Raptor Lake) generation. It is fabricated on Intel's 10 nm process node at Intel's own foundry. The Lisuan Tech LX PRO uses the 7G105 chip with a "TrueGPU" architecture from the 7G100 generation, manufactured on TSMC's 6 nm process. The process node difference (10 nm versus 6 nm) suggests the LX PRO benefits from a denser, more modern manufacturing process, though the database does not list transistor counts or die sizes for either part.

Core configuration differs dramatically. The Iris Xe packs 640 shading units, 40 texture mapping units, and 20 raster operation pipelines. The LX PRO scales this up to 6144 shading units, 192 TMUs, and 96 ROPs. That represents a 9.6x increase in shading units, a 4.8x increase in TMUs, and a 4.8x increase in ROPs. Neither GPU lists dedicated ray tracing cores or tensor cores, so both rely on traditional shader-based rendering paths.

Memory architecture represents a fundamental split. The Iris Xe uses system-shared memory with no dedicated VRAM, relying on the host system's RAM for both capacity and bandwidth. The LX PRO carries 24 GB of GDDR6 across a 192-bit bus, with memory clocks at 2250 MHz (18 Gbps effective) yielding 432.0 GB/s of bandwidth. The Iris Xe's memory clock is listed as "System Shared" and its bandwidth as "System Dependent," meaning its memory performance varies with the host platform.

API support also diverges. The Iris Xe supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The LX PRO supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The LX PRO's DirectX 12_2 feature level enables hardware-accelerated ray tracing and mesh shaders through the DirectX 12 Ultimate specification, while the Iris Xe's 12_1 level lacks those features. Vulkan support is slightly higher on the Iris Xe (1.4 versus 1.3), though the database does not specify which Vulkan extensions differ.

Power and physical design reflect their intended roles. The Iris Xe is an integrated GPU (IGP) with a 15 W TDP, mounted on the processor die with a Ring Bus interface. The LX PRO is a dual-slot discrete card drawing 225 W, requiring a single 16-pin power connector and a 550 W suggested power supply. The LX PRO measures 248 mm in length, 118 mm in height, and 48 mm in width. The Iris Xe has no listed dimensions because it is not a separate physical card.

Where Each One Wins

The Lisuan Tech LX PRO wins in every scenario that demands raw computational throughput. Its 24.58 TFLOPS FP32 performance suits heavy 3D rendering, scientific simulation, and AI inference workloads that rely on massive parallel shader counts. The 24 GB GDDR6 frame buffer with 432.0 GB/s bandwidth allows large texture sets, high-resolution assets, and multi-monitor output across four DisplayPort 1.4a connections. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate handle high-resolution rendering with dense geometry and detailed textures. The DirectX 12 Ultimate support enables ray-traced effects and modern rendering pipelines that the Iris Xe cannot execute at the hardware feature level.

The Intel Iris Xe Graphics 80EU Mobile wins in scenarios where power efficiency and system integration matter more than peak performance. Its 15 W TDP fits into thin-and-light laptops and compact desktops without discrete graphics. The system-shared memory model eliminates the need for a separate VRAM pool, reducing BOM cost and physical footprint. The Ring Bus interface connects directly to the CPU, lowering latency for memory access in integrated workloads. The Vulkan 1.4 support provides a newer API revision than the LX PRO's 1.3, which may benefit certain compute or rendering applications that use newer Vulkan extensions.

For gaming at 1080p with modest settings, the Iris Xe can handle esports titles and older games, while the LX PRO targets 1440p or 4K gaming with high detail levels and ray tracing enabled. Content creators working with large video timelines or 3D scenes will find the LX PRO's 24 GB memory capacity essential for caching frames and geometry. The Iris Xe's system-shared memory means it borrows from the main RAM pool, which can starve CPU workloads in memory-constrained systems.

The LX PRO's four DisplayPort 1.4a outputs support multi-monitor productivity setups or surround gaming, while the Iris Xe's display outputs are listed as "Portable Device Dependent," meaning they vary by laptop or motherboard implementation. The LX PRO's dual-slot cooler and 225 W TDP require adequate chassis airflow, while the Iris Xe produces minimal heat within the CPU package.
