Intel UHD Graphics 770 Mobile vs Lisuan Tech LX 7G100 Comparison

Head-to-Head Benchmarks

The benchmark database shows no recorded head-to-head comparisons for these two parts, and neither has accumulated any benchmark scores. What the data does provide is a set of raw hardware specifications that allow for direct theoretical comparison. The Intel UHD Graphics 770 Mobile is a 15 W integrated graphics processor from the Raptor Lake generation, built on Intel's 10 nm process. The Lisuan Tech LX 7G100 is a 225 W dual-slot discrete graphics card based on the 7G106 chip, fabricated by TSMC on a 6 nm process. The performance gap between them, based purely on the recorded specifications, is enormous.

The most decisive numbers come from the FP32 floating-point throughput. The Lisuan Tech LX 7G100 delivers 24.58 TFLOPS, while the Intel UHD Graphics 770 Mobile produces 819.2 GFLOPS. That is a 30x difference in raw compute. In practical terms, the LX 7G100 can handle workloads that are simply outside the reach of the integrated Intel part. The FP16 figures tell the same story: the LX 7G100 reaches 49.15 TFLOPS (2:1) versus 1.638 TFLOPS (2:1) for the UHD 770. Any rendering task, simulation, or compute workload that scales with shader throughput will heavily favor the Lisuan card.

Pixel and texture throughput reinforce the divide. The LX 7G100 has a pixel rate of 192.0 GPixel/s and a texture rate of 384.0 GTexel/s. The UHD 770 Mobile manages 12.80 GPixel/s and 25.60 GTexel/s. That is 15x higher pixel throughput and 15x higher texture throughput for the Lisuan part. At higher resolutions and with detailed textures, the LX 7G100 will maintain frame rates that the Intel integrated solution cannot approach.

The memory subsystem is another area of clear separation. The LX 7G100 has 12 GB of GDDR6 memory on a 192-bit bus, with a bandwidth of 432.0 GB/s. The UHD 770 Mobile uses System Shared memory, meaning it borrows from the main system RAM, and its bandwidth is listed as System Dependent. The dedicated memory of the LX 7G100 provides consistent, high-speed access that does not contend with the CPU for bandwidth. The Intel part's performance will vary with the system's memory configuration, but it cannot match the raw 432.0 GB/s figure.

The shading units, texture mapping units, and raster operation units all favor the Lisuan card by a wide margin. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs. The UHD 770 Mobile has 256 shading units, 16 TMUs, and 8 ROPs. The LX 7G100 has 24x more shading units, 12x more TMUs, and 12x more ROPs. These structural differences make the performance gap structural rather than marginal.

The Verdict

The data separates these two products into entirely different categories. The Intel UHD Graphics 770 Mobile is an integrated graphics solution for portable devices, with a 15 W TDP and a Ring Bus interface. The Lisuan Tech LX 7G100 is a 225 W discrete graphics card with a PCIe 4.0 x16 interface, a dual-slot cooler, and a single 8-pin power connector. The database indicates that the UHD 770 is a generation 12.2 part from Intel, while the LX 7G100 uses a TrueGPU architecture.

For anyone building a system that needs to run graphically demanding applications, the LX 7G100 is the only viable option between these two. Its 24.58 TFLOPS FP32 performance, 432.0 GB/s memory bandwidth, and 12 GB of dedicated GDDR6 memory place it in a completely different performance class. The UHD 770 Mobile, despite its 1600 MHz boost clock, cannot deliver playable performance in modern games or accelerate compute workloads to any meaningful degree.

The UHD 770 Mobile does have advantages, but they are not performance advantages. It consumes only 15 W, requires no additional power connectors, and fits as an IGP on the Ring Bus. The LX 7G100 requires a 550 W suggested power supply and occupies a dual-slot footprint measuring 294 mm in length. For a portable device or a low-power office system, the Intel part makes sense. For anything else, the Lisuan card is the clear choice.

Architecture Differences

The Intel UHD Graphics 770 Mobile is built on Raptor Lake, using Intel's Generation 12.2 architecture. It is manufactured on a 10 nm process at Intel's own foundry. The architecture is a continuation of Intel's Xe-based integrated graphics design, with 256 shading units arranged across 16 TMUs and 8 ROPs. The chip uses a Ring Bus interface, indicating it is integrated into the CPU die rather than being a separate discrete processor. Its API support includes DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4.

The Lisuan Tech LX 7G100 uses a TrueGPU architecture, built around the 7G106 chip. It is manufactured by TSMC on a 6 nm process, which is a more advanced node than the Intel 10 nm process used for the UHD 770. The LX 7G100 has 6144 shading units, 192 TMUs, and 96 ROPs, indicating a much larger and more complex die. It connects via PCIe 4.0 x16, a standard discrete GPU interface. Its API support includes DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The DirectX 12 Ultimate designation includes features like hardware ray tracing support, though the database does not list dedicated RT cores for either product.

The process node difference is significant. TSMC's 6 nm process offers higher transistor density and better power efficiency per transistor than Intel's 10 nm process. This allows the LX 7G100 to pack 6144 shading units into a chip that operates within a 225 W TDP. The Intel part, with only 256 shading units, is limited by the constraints of being integrated into a CPU package with a 15 W TDP.

Specification Differences

The specifications differ in nearly every category. The Intel UHD Graphics 770 Mobile has a base clock of 300 MHz and a boost clock of 1600 MHz. The LX 7G100 does not have recorded base or boost clock figures, but its memory operates at 2250 MHz with 18 Gbps effective speed. The Intel part's memory is System Shared, with no dedicated VRAM. The LX 7G100 has 12 GB of GDDR6 on a 192-bit bus.

The TDP difference is the most operationally relevant specification. The UHD 770 Mobile consumes 15 W, while the LX 7G100 consumes 225 W. The LX 7G100 requires a 1x 8-pin power connector and a suggested power supply of 550 W. The Intel part requires no power connectors and has no suggested PSU figure. The LX 7G100 is a dual-slot card measuring 294 mm in length, 120 mm in height, and 49 mm in width. The UHD 770 Mobile is an IGP with no recorded dimensions.

The display outputs also differ. The LX 7G100 provides 4x DisplayPort 1.4a outputs. The UHD 770 Mobile's display outputs are listed as Portable Device Dependent, meaning they vary by the laptop or device it is integrated into. The LX 7G100 uses PCIe 4.0 x16, while the Intel part uses Ring Bus. The release dates differ substantially: the UHD 770 Mobile was released in 2023, while the LX 7G100 has a 2026 release date.

Where Each One Wins

The Intel UHD Graphics 770 Mobile wins in power efficiency and integration. Its 15 W TDP makes it suitable for portable devices where battery life and thermal limits are primary concerns. The Ring Bus interface means it is part of the CPU package, requiring no additional board space, power connectors, or cooling beyond what the laptop or small-form-factor system already provides. The database lists its display outputs as Portable Device Dependent, confirming its role in mobile systems. For office work, web browsing, video playback, and light 2D graphics, the UHD 770 Mobile provides adequate performance with minimal power draw.

The Lisuan Tech LX 7G100 wins in every performance metric recorded. Its FP32 throughput of 24.58 TFLOPS, texture rate of 384.0 GTexel/s, and pixel rate of 192.0 GPixel/s place it in a class that can handle modern gaming, 3D rendering, and compute workloads. The 12 GB of GDDR6 memory with 432.0 GB/s bandwidth provides ample capacity and speed for large textures and data sets. The DirectX 12 Ultimate support enables the latest graphics features. The 4x DisplayPort 1.4a outputs support multi-monitor setups. The 225 W TDP and dual-slot design indicate a card intended for a desktop workstation or gaming rig with adequate power delivery and cooling.

The database shows no head-to-head wins for either product, but the specification comparison leaves no ambiguity. The LX 7G100 is designed for performance, and the UHD 770 Mobile is designed for efficiency. A user with a portable device will choose the Intel part because the Lisuan card physically cannot fit or be powered in such a system. A user with a desktop and a 550 W power supply will choose the LX 7G100 for any task requiring substantial graphics throughput. The architectural differences, from process node to memory interface to shader count, all point in the same direction: the LX 7G100 delivers roughly 30x the FP32 compute of the UHD 770 Mobile, and that gap defines their respective roles.
