The Verdict

The data indicates a split decision. The Intel Arc B770 is the choice for workloads that depend on memory capacity, memory bandwidth, and rasterization throughput. Its 16 GB frame buffer and 512.0 GB/s bandwidth, combined with 128 ROPs and a 307.2 GPixel/s pixel rate, give it a structural edge in high-resolution rendering and texture-heavy scenarios.

The Lisuan Tech LX 7G100 is the choice for raw compute throughput and geometric processing. Its 6144 shading units and 24.58 TFLOPS FP32 peak exceed the Arc B770's figures, and its higher shading unit count suggests stronger shader-bound performance. The LX 7G100 also has a more recent release date, June 2025 versus December 2025 for the Arc B770, and an active production status.

Neither card has recorded benchmark scores or nearest rival data in the database. Both hold a 50th percentile rank against all GPUs, and both have an average benchmark score of zero. The verdict rests entirely on specification analysis. Users prioritizing frame buffer size and pixel throughput should select the Intel Arc B770. Users prioritizing shader count and FP32 compute should select the Lisuan Tech LX 7G100.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results, no wins for either card, and no benchmark score entries. The comparison must therefore be drawn from the specification sheet.

The Lisuan Tech LX 7G100 leads in shading units by a wide margin: 6144 versus 4096, a 50% advantage. That difference appears directly in the FP32 peak: 24.58 TFLOPS versus 19.66 TFLOPS, which is approximately 25% higher. The FP16 peak follows the same pattern, 49.15 TFLOPS versus 39.32 TFLOPS. These figures indicate that the LX 7G100 should outperform the Arc B770 in compute-bound tasks such as shader-heavy effects, simulation, and FP32 general-purpose workloads.

The Intel Arc B770 counters in memory and rasterization. Its 16 GB capacity exceeds the LX 7G100's 12 GB by 4 GB. Its 256-bit bus width and 512.0 GB/s bandwidth exceed the LX 7G100's 192-bit bus and 432.0 GB/s by 80 GB/s. The Arc B770 also has 128 ROPs versus 96, and a pixel rate of 307.2 GPixel/s versus 192.0 GPixel/s. That is a 60% advantage in pixel fill rate. Its texture rate of 614.4 GTexel/s versus 384.0 GTexel/s represents a 60% advantage in texture fill rate as well.

The ray tracing comparison is one-sided in specification. The Arc B770 has 32 dedicated RT cores. The LX 7G100 has no RT core count listed. The Arc B770 also supports Vulkan 1.4, while the LX 7G100 supports Vulkan 1.3. The LX 7G100 has no listed RT cores, so the Arc B770 is the only card with explicit ray tracing hardware in the record.

The LX 7G100 does hold a clock speed advantage in memory, 2250 MHz (18 Gbps effective) versus 2000 MHz (16 Gbps effective), but the narrower bus still yields lower total bandwidth. The Arc B770 lists a base clock of 2100 MHz and a boost clock of 2400 MHz; the LX 7G100 has no base or boost clock recorded.

Architecture Differences

The Intel Arc B770 is built on the Xe2-HPG architecture, part of the Battlemage generation (Arc 7). Its predecessor is listed as Alchemist. The chip is BMG-G31. The LX 7G100 uses an architecture called TrueGPU, with the chip designation 7G106, and no predecessor listed.

The process nodes differ: 5 nm for the Arc B770 versus 6 nm for the LX 7G100, both at TSMC. The Arc B770 has a known die size of 368 mm²; the LX 7G100 has no die size recorded.

The shading unit counts suggest different design philosophies. The Arc B770 allocates more silicon to TMUs and ROPs relative to its shader count, with 256 TMUs and 128 ROPs. The LX 7G100 allocates more silicon to shading units, 6144, but fewer to TMUs, 192, and ROPs, 96. The Arc B770's ratio of TMUs to shading units is 1:16, while the LX 7G100's is 1:32. The Arc B770's ratio of ROPs to shading units is 1:32, while the LX 7G100's is 1:64.

Ray tracing hardware exists only on the Arc B770, with 32 RT cores. The LX 7G100 has no RT core field populated. The Arc B770 also has a higher Vulkan API version, 1.4 versus 1.3.

The Arc B770's memory clock is lower than the LX 7G100's, but its wider bus and larger die size compensate in total bandwidth. The LX 7G100's higher shader count drives its higher FP32 and FP16 peaks, but its narrower memory bus and lower ROP count limit its fill rates relative to the Arc B770.

Where Each One Wins

The Intel Arc B770 wins in memory capacity, memory bandwidth, pixel fill rate, texture fill rate, ray tracing, and display output standards. Its 16 GB frame buffer and 512.0 GB/s bandwidth suit high-resolution textures, large datasets, and multi-tasking with multiple displays. Its 128 ROPs and 307.2 GPixel/s pixel rate favor traditional rasterization at high resolutions. Its 32 RT cores give it explicit ray tracing capability, which the LX 7G100 lacks. Its DisplayPort 2.1 support is a newer standard than the LX 7G100's DisplayPort 1.4a.

The Lisuan Tech LX 7G100 wins in shading unit count, FP32 peak, FP16 peak, memory clock speed, and physical dimensions. Its 6144 shading units and 24.58 TFLOPS FP32 peak favor compute-heavy workloads such as shader-bound rendering, general-purpose GPU compute, and FP32 math. Its 49.15 TFLOPS FP16 peak doubles the FP32 figure, indicating strong half-precision throughput for workloads that can use it. Its higher memory clock, 2250 MHz versus 2000 MHz, partially offsets its narrower bus. Its confirmed active production status and recorded dimensions indicate a shipping product with known physical requirements.

The database shows no benchmark wins for either card, so these use-case splits derive from the specification record. The Arc B770 is positioned for memory-intensive and rasterization-heavy tasks, with ray tracing as a distinct feature. The LX 7G100 is positioned for shader-heavy and compute-intensive tasks, with peak throughput as its primary advantage.
