Intel Iris Xe Graphics 80EU Mobile vs Lisuan Tech LX 7G100 Comparison

Where Each One Wins

The Intel Iris Xe Graphics 80EU Mobile and the Lisuan Tech LX 7G100 occupy completely different segments of the GPU market, and their respective strengths follow directly from their design goals. The Iris Xe is an integrated graphics processor built for thin-and-light laptops, while the LX 7G100 is a discrete, dual-slot desktop card with its own dedicated memory and power delivery.

The Iris Xe delivers its wins in the integrated space: it uses system-shared memory, consumes only 15 W, and slots into the Ring Bus interface of Raptor Lake processors. Its production status is Active with a release date of January 3, 2023, and its successor is listed as Arc Graphics-M. The LX 7G100, by contrast, is a standalone expansion card that requires a PCIe 4.0 x16 slot, a 550 W suggested PSU, and a single 8-pin power connector. It was released on June 17, 2026, and has no successor listed.

The LX 7G100 wins decisively on raw compute throughput. Its FP32 performance of 24.58 TFLOPS is more than 13 times the Iris Xe's 1.856 TFLOPS. Its pixel rate of 192.0 GPixel/s versus 29.00 GPixel/s and texture rate of 384.0 GTexel/s versus 58.00 GTexel/s show a similar magnitude of advantage. The LX 7G100 also carries 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s of bandwidth, whereas the Iris Xe relies entirely on system-shared memory with bandwidth described as system dependent.

The Iris Xe wins on power efficiency and integration. At 15 W, it draws a fraction of the LX 7G100's 225 W. It requires no power connectors, no extra cooling beyond the laptop chassis, and no PSU headroom beyond what the host system already provides. The LX 7G100 is a dual-slot card measuring 294 mm in length, 120 mm in height, and 49 mm in width, so it demands physical space and active cooling.

Architecture Differences

The two GPUs use fundamentally different architectures, process nodes, and foundries. The Iris Xe is built on Intel's Generation 12.2 architecture, implemented on a 10 nm process at Intel's own foundry. It belongs to the HD Graphics-M generation for Raptor Lake, which is the chip it pairs with. The LX 7G100 uses an architecture called TrueGPU, fabricated on a 6 nm process at TSMC, and belongs to the 7G100 generation with the 7G106 chip.

Shader configuration differs substantially. The Iris Xe has 640 shading units, 40 texture mapping units, and 20 ROPs. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. That is roughly 9.6 times the shading units, 4.8 times the TMUs, and 4.8 times the ROPs. Neither GPU lists RT cores or tensor cores, so ray tracing and AI acceleration, if present, are not quantified in the database.

Memory architecture is the most striking difference. The Iris Xe uses system-shared memory for both size and type, with no dedicated VRAM. The LX 7G100 has 12 GB of GDDR6 on a 192-bit bus, running at 2250 MHz with 18 Gbps effective speed. This gives it 432.0 GB/s of bandwidth, a figure that is entirely independent of the host system's RAM. The Iris Xe's bandwidth is listed as system dependent, meaning it varies with the laptop's memory configuration.

API support also differs. The Iris Xe supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The LX 7G100 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The LX 7G100 has a higher DirectX feature level, while the Iris Xe has a slightly newer Vulkan revision. The LX 7G100 also provides 4x DisplayPort 1.4a outputs, whereas the Iris Xe's display outputs are portable device dependent, meaning they vary by laptop design.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark scores for these two GPUs, and neither has any recorded benchmark entries. However, the specification-level numbers allow for direct comparison of theoretical peak performance. The LX 7G100's FP32 throughput of 24.58 TFLOPS is approximately 13.2 times the Iris Xe's 1.856 TFLOPS. In FP16, the LX 7G100 reaches 49.15 TFLOPS versus the Iris Xe's 3.712 TFLOPS, a ratio of roughly 13.2 as well, since both operate at a 2:1 FP16 to FP32 ratio.

Pixel throughput tells a similar story. The LX 7G100 renders at 192.0 GPixel/s, which is about 6.6 times the Iris Xe's 29.00 GPixel/s. Texture throughput is 384.0 GTexel/s versus 58.00 GTexel/s, a factor of about 6.6 as well. The consistent ratios across pixel and texture rates reflect the relatively similar ROP and TMU scaling relative to shader count.

Memory bandwidth is where the gap is largest. The LX 7G100's 432.0 GB/s is not directly comparable to the Iris Xe's system dependent figure, but the qualitative difference is clear: one has dedicated GDDR6, the other shares system memory. In a laptop with dual-channel DDR4 or DDR5, the Iris Xe would typically see bandwidth in the tens of GB/s range, while the LX 7G100 has a fixed 432.0 GB/s.

Both GPUs sit at the 50th percentile versus all GPUs in the database, and both have an average benchmark score of zero, reflecting the absence of recorded benchmark runs. This means the percentile ranking is provisional and based on specifications rather than measured performance.
