Intel Arc B770 vs Lisuan Tech LX PRO Comparison

The Verdict

The database shows two very different interpretations of a 225 W dual-slot graphics card. The Intel Arc B770 is a mainstream-oriented design built around a 5 nm TSMC process, with a 256-bit memory bus and 16 GB of GDDR6. The Lisuan Tech LX PRO takes a different route: it uses a 6 nm process, packs more shading units, and carries 24 GB of GDDR6 on a narrower 192-bit bus. For builders who prioritize raw FP32 throughput and large memory capacity for content creation or AI workloads, the LX PRO holds the arithmetic edge. For those who favor balanced rasterization resources, higher pixel throughput, and a wider memory interface, the Arc B770 is the more conventional pick.

Benchmark results in the database do not separate the two cards: both sit at the 50th percentile among all GPUs, and their average benchmark scores are recorded as zero. That means the verdict here has to be drawn from specification-level analysis rather than measured performance deltas. The data indicates the LX PRO delivers 24.58 TFLOPS of FP32 compute versus 19.66 TFLOPS for the Arc B770, a 25% advantage in raw shader math. Memory capacity is also a clear win for the LX PRO at 24 GB versus 16 GB. However, the Arc B770 counters with 512.0 GB/s of bandwidth versus 432.0 GB/s, a 19% lead in memory throughput, and a pixel rate of 307.2 GPixel/s versus 192.0 GPixel/s, a 60% advantage in fill-rate-bound scenarios.

The practical interpretation: the Lisuan Tech LX PRO is the pick for compute-heavy tasks where FP32 throughput and large working sets matter. The Intel Arc B770 is the pick for high-resolution rasterization and scenarios that depend on fill rate, texture throughput, or the wider memory bus. Neither card has a recorded win in head-to-head benchmarks, so the choice ultimately rests on workload profile.

Architecture Differences

The Intel Arc B770 uses the Xe2-HPG architecture on the BMG-G31 chip, built on a 5 nm process at TSMC. It belongs to the Battlemage (Arc 7) generation, succeeding the Alchemist architecture. The chip has a die size of 368 mm². The architecture emphasizes a balanced mix of shading, texture, and raster resources, with 4096 shading units, 256 TMUs, and 128 ROPs. It also includes 32 dedicated ray tracing cores, which the LX PRO does not list in its specification.

The Lisuan Tech LX PRO uses the TrueGPU architecture on the 7G105 chip, fabricated on a 6 nm process, also at TSMC. It belongs to the 7G100 generation. The LX PRO has no listed ray tracing cores, which suggests a design focused on conventional compute and memory capacity rather than hybrid rendering features. Its shading unit count is substantially higher at 6144, but its TMU count is lower at 192, and its ROP count is lower at 96. That configuration favors arithmetic throughput over texture and pixel fill.

Both cards use GDDR6 memory, but the memory architecture differs significantly. The Arc B770 uses a 256-bit bus, while the LX PRO uses a 192-bit bus. The Arc B770 runs its memory at 2000 MHz with 16 Gbps effective speed, while the LX PRO runs at 2250 MHz with 18 Gbps effective speed. The wider bus on the Arc B770 compensates for the lower clock, resulting in higher overall bandwidth. The LX PRO compensates with a larger capacity, 24 GB versus 16 GB.

The API support also differs in one key area: the Arc B770 supports Vulkan 1.4, while the LX PRO supports Vulkan 1.3. Both cards support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The Arc B770's display outputs include 1x HDMI 2.1a and 3x DisplayPort 2.1, while the LX PRO offers 4x DisplayPort 1.4a. The LX PRO is listed as having an active production status, while the Arc B770 does not have a production status recorded.

Both cards share a 225 W TDP, dual-slot cooling, a PCIe 4.0 x16 interface, and a suggested 550 W power supply. The power connectors differ: the Arc B770 uses 1x 6-pin plus 1x 8-pin, while the LX PRO uses 1x 16-pin. Display outputs differ as noted. The LX PRO has recorded physical dimensions: 248 mm in length, 118 mm in height, and 48 mm in width. The Arc B770 has no dimensions listed. The release dates also differ, with the Arc B770 dated earlier and the LX PRO dated later.

Head-to-Head Benchmarks

The database records no head-to-head benchmark entries for these two cards, and neither card has a recorded win count. The percentile ranking for both is identical at 50, meaning they sit at the median of all GPUs in the database. Without measured benchmark scores, the comparison relies on the specification-level deltas.

The most significant arithmetic win for the Lisuan Tech LX PRO is in FP32 compute. At 24.58 TFLOPS, it is 25% ahead of the Arc B770's 19.66 TFLOPS. In FP16 compute, the gap is similar: 49.15 TFLOPS versus 39.32 TFLOPS, a 25% lead. Shading unit count also favors the LX PRO, with 6144 units versus 4096, a 50% increase. Memory capacity favors the LX PRO by 50% as well, at 24 GB versus 16 GB.

The Arc B770 takes the lead in memory bandwidth, texture rate, and pixel rate. Bandwidth is 512.0 GB/s versus 432.0 GB/s, a 19% advantage. Texture rate is 614.4 GTexel/s versus 384.0 GTexel/s, a 60% advantage. Pixel rate is 307.2 GPixel/s versus 192.0 GPixel/s, also a 60% advantage. The Arc B770 has more TMUs (256 versus 192) and more ROPs (128 versus 96), which explains those fill-rate wins. The Arc B770 also has 32 ray tracing cores, while the LX PRO lists none.

The memory interface difference is telling. The Arc B770's 256-bit bus with 16 GB is a classic rasterization setup, trading capacity for bandwidth. The LX PRO's 192-bit bus with 24 GB is a capacity-first setup, trading bandwidth for working memory. In workloads that stream large amounts of data per frame, the Arc B770 has the throughput edge. In workloads that need to hold large datasets entirely in VRAM, the LX PRO has the capacity edge.

Where Each One Wins

The Intel Arc B770 wins in scenarios that depend on fill rate and memory throughput. The 60% higher pixel rate makes it the stronger candidate for high-resolution rasterization with heavy overdraw, such as MSAA or high-res shadow rendering. The 60% higher texture rate, driven by 256 TMUs, favors texture-heavy scenes with complex material sampling. The 19% higher memory bandwidth helps when shaders repeatedly access large texture arrays or geometry buffers. The presence of 32 ray tracing cores gives it a feature advantage for hybrid rendering workloads, though no benchmark data quantifies that advantage.

The Lisuan Tech LX PRO wins in scenarios that depend on raw compute throughput and memory capacity. The 25% higher FP32 performance and the 50% higher shading unit count make it the stronger candidate for compute shaders, physics simulation, and AI inference tasks that run on FP32 math. The 50% larger memory capacity allows it to load datasets that would exceed the Arc B770's 16 GB limit, such as larger language models, higher-resolution volumetric data, or multi-texture baking workflows. The higher memory clock, 18 Gbps effective versus 16 Gbps effective, partially offsets its narrower bus.

For a builder assembling a gaming system that targets high refresh rates at 1440p or 4K, the Arc B770's pixel and texture throughput aligns with rasterization demands. For a workstation that runs render farms, simulation, or machine learning batch jobs, the LX PRO's compute throughput and 24 GB capacity align with those workloads. The LX PRO also has a longer physical footprint at 248 mm, which may require case clearance checks. Both cards fit dual-slot layouts and share the same 225 W TDP and 550 W PSU recommendation, so system power planning is identical. The choice between them is a choice between bandwidth and capacity, or between fill rate and compute, with no measured head-to-head results to break the tie.
