Intel Arc Graphics 64EU Mobile vs Lisuan Tech LX ULTRA Comparison

Architecture Differences

The Intel Arc Graphics 64EU Mobile and the Lisuan Tech LX ULTRA represent fundamentally different design philosophies. The Intel part is an integrated graphics processor built on the Meteor Lake chip, using the Xe-LPG architecture. It is manufactured on Intel's 10 nm process node and fabricated by Intel itself. The LX ULTRA is a discrete, add-in-board graphics card based on the 7G105 chip, using the TrueGPU architecture, and is manufactured on TSMC's 6 nm process node.

The most striking difference lies in the scale of each design. The Intel Arc Graphics 64EU Mobile deploys 512 shading units, 32 texture mapping units, and 16 raster output units. The Lisuan Tech LX ULTRA, by contrast, packs 6144 shading units, 192 TMUs, and 96 ROPs. That is a 12x difference in shading units, a 6x difference in TMUs, and a 6x difference in ROPs. The LX ULTRA is built for raw throughput, while the Intel part is optimized for power efficiency within a mobile package.

Memory architecture separates the two completely. The Intel Arc Graphics 64EU Mobile uses System Shared memory, meaning it borrows from the host system's RAM. Its memory clock is listed as System Shared, and its bandwidth is System Dependent. The LX ULTRA, however, comes with 24 GB of dedicated GDDR6 memory on a 192-bit bus, running at 2250 MHz with 18 Gbps effective speed. This yields a fixed bandwidth of 432.0 GB/s, a figure the Intel part cannot match because its bandwidth is contingent on the host platform.

The power envelopes are equally divergent. The Intel Arc Graphics 64EU Mobile has a TDP of 65 W and is an IGP, meaning it is integrated into the motherboard or CPU package. The LX ULTRA draws 225 W, requires a 550 W suggested power supply, uses a 1x 16-pin power connector, and occupies a dual-slot form factor. The Intel part uses a Ring Bus interface, while the LX ULTRA connects via PCIe 4.0 x16.

API support shows a generational gap. The Intel part supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The LX ULTRA supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3. The LX ULTRA's DirectX 12 Ultimate designation indicates support for the full feature set of the modern DirectX 12 API, including hardware ray tracing and mesh shaders, whereas the Intel part's 12_1 level is a more limited subset. The Intel part edges ahead in Vulkan version support (1.4 versus 1.3).

Display outputs also differ. The Intel Arc Graphics 64EU Mobile's outputs are Portable Device Dependent, reflecting its mobile integration. The LX ULTRA offers 4x DisplayPort 1.4a outputs, a standard configuration for a desktop discrete card.

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between these two parts. However, the theoretical throughput figures provide a clear basis for comparison. The LX ULTRA delivers 24.58 TFLOPS of FP32 compute, while the Intel Arc Graphics 64EU Mobile delivers 1.792 TFLOPS. That places the LX ULTRA roughly 13.7x ahead in single-precision floating-point performance. The margin is derived directly from the shading unit count and clock behavior; the Intel part boosts to 1750 MHz, while the LX ULTRA's boost clock is not listed in the database.

In FP16 compute, the LX ULTRA achieves 49.15 TFLOPS (2:1 ratio), versus 3.584 TFLOPS (2:1 ratio) for the Intel part. Again, the LX ULTRA holds a commanding lead, this time by a factor of approximately 13.7x. These figures represent peak theoretical rates, not real-world application performance, but they establish the upper bound of what each architecture can deliver.

Texture and pixel throughput follow the same pattern. The LX ULTRA's texture rate is 384.0 GTexel/s, compared to 56.00 GTexel/s for the Intel part. That is a 6.9x advantage. The pixel rate for the LX ULTRA is 192.0 GPixel/s, versus 28.00 GPixel/s for the Intel part, a 6.9x advantage. These ratios align closely with the TMU and ROP counts, confirming that the LX ULTRA scales its output stages proportionally.

The LX ULTRA's memory bandwidth of 432.0 GB/s is a fixed, dedicated resource. The Intel part's bandwidth is System Dependent, so no direct numeric comparison is possible. In practice, a discrete GDDR6 implementation with a 192-bit bus will vastly outperform shared system memory in bandwidth-sensitive workloads, but the database does not provide a matching figure for the Intel part.

Neither part has any recorded benchmark scores in the database, and both share the same percentileVsAllGpus value of 50. The avgBenchmarkScore for both is 0. This means the database currently holds no empirical test results for either product; the analysis here relies entirely on the architectural and theoretical specifications recorded.

Where Each One Wins

The Lisuan Tech LX ULTRA wins decisively in every raw performance metric recorded. Its FP32 compute, FP16 compute, texture rate, and pixel rate all exceed the Intel Arc Graphics 64EU Mobile by factors ranging from 6.9x to 13.7x. This makes it suited for workloads that demand sustained throughput: high-resolution rendering, compute-heavy simulation, and large texture datasets. Its 24 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s bandwidth provides a dedicated memory pool that does not compete with the host system. The dual-slot form factor and 225 W TDP indicate a card designed for stationary desktop use with adequate cooling.

The Intel Arc Graphics 64EU Mobile wins in power efficiency and integration. Its 65 W TDP is less than a third of the LX ULTRA's 225 W draw. As an IGP with a Ring Bus interface, it requires no separate power connector, no PCIe slot, and no additional cooling beyond what the laptop chassis provides. Its display outputs are Portable Device Dependent, meaning it works wherever the host device is designed to output video. For mobile platforms, this is the only viable option of the two; the LX ULTRA's 268 mm length, dual-slot width, and 16-pin power connector preclude its use in portable systems.

The Intel part also holds a Vulkan API advantage, supporting version 1.4 versus the LX ULTRA's 1.3. This could matter in Vulkan-based applications that use newer extensions, though the practical impact is workload-specific. The LX ULTRA counters with DirectX 12 Ultimate (12_2), which is a higher feature level than the Intel part's DirectX 12 (12_1). For DirectX-based games and applications, the LX ULTRA has access to the full modern feature set.

The LX ULTRA also wins on display connectivity for desktop use, offering 4x DisplayPort 1.4a outputs. The Intel part's outputs depend entirely on the portable device it is integrated into. For multi-monitor desktop setups, the LX ULTRA provides a fixed, known quantity of outputs.
