Intel Arc Pro B70 vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark runs between the Intel Arc Pro B70 and the Lisuan Tech LX ULTRA. Both entries in the database have empty benchmark arrays, zero average benchmark scores, and zero wins in the head-to-head matrix. The percentile field places both cards at the 50th percentile against all GPUs, indicating neither has accumulated measurable performance data in the database at this time.

Without actual benchmark results, the comparison must rely on the specified compute characteristics. The Intel Arc Pro B70 delivers 22.94 TFLOPS of FP32 compute, while the Lisuan Tech LX ULTRA delivers 24.58 TFLOPS. That places the LX ULTRA ahead by 1.64 TFLOPS, roughly 7% higher in raw single-precision throughput. In FP16, the B70 produces 45.88 TFLOPS using a 2:1 ratio, while the LX ULTRA produces 49.15 TFLOPS, again favoring the Lisuan part by 3.27 TFLOPS.

The pixel throughput figures show a different story. The Intel B70 reaches 358.4 GPixel/s, which is 166.4 GPixel/s higher than the LX ULTRA's 192.0 GPixel/s. That gap represents an 87% advantage for Intel in fill-rate-bound workloads. Texture rate follows the same pattern: the B70 delivers 716.8 GTexel/s versus 384.0 GTexel/s for the LX ULTRA, a difference of 332.8 GTexel/s, or roughly 87% higher texture throughput.

Memory bandwidth also splits the two cards clearly. The B70 uses a 256-bit bus with 32 GB of GDDR6 running at 2375 MHz (19 Gbps effective), yielding 608.0 GB/s. The LX ULTRA uses a 192-bit bus with 24 GB of GDDR6 at 2250 MHz (18 Gbps effective), yielding 432.0 GB/s. Intel holds a 176.0 GB/s advantage, which is approximately 41% more bandwidth. The B70 also has a larger memory pool by 8 GB.

Shader and geometry resources differ substantially. The B70 contains 4096 shading units, 256 TMUs, and 128 ROPs, plus 32 dedicated ray tracing cores. The LX ULTRA contains 6144 shading units, 192 TMUs, and 96 ROPs, with no ray tracing core count listed. The LX ULTRA has 2048 more shading units, but Intel has 64 more TMUs and 32 more ROPs. This configuration suggests the LX ULTRA leans on compute-heavy shader work, while the B70 allocates more hardware toward texture and pixel processing.

Clock speeds also favor Intel. The B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The LX ULTRA lists neither a base nor a boost clock in the database, so no direct frequency comparison is possible. The memory clock on the B70 is 2375 MHz versus 2250 MHz on the LX ULTRA, a 125 MHz difference that contributes to the bandwidth gap.

Where Each One Wins

The Intel Arc Pro B70 wins in scenarios that stress memory bandwidth, pixel fill rate, and texture throughput. The 608.0 GB/s bandwidth and 358.4 GPixel/s pixel rate make it the stronger candidate for high-resolution rendering, heavy post-processing effects, and scenes with large texture sets. The 32 GB frame buffer also provides headroom for very large datasets, such as multi-monitor setups or compute workloads that map large buffers to video memory. The 32 ray tracing cores give it an explicit hardware path for RT workloads, something the LX ULTRA does not list.

The Lisuan Tech LX ULTRA wins in raw compute throughput. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 figures exceed the B70's 22.94 TFLOPS and 45.88 TFLOPS respectively. The 6144 shading units provide 50% more shader hardware than the B70's 4096, which can benefit compute-heavy tasks such as physics simulation, machine learning inference, or general-purpose GPGPU work that does not rely heavily on memory bandwidth. The LX ULTRA also uses a 6 nm process node versus 5 nm on the B70, though both come from TSMC.

Power draw is nearly identical. The B70 has a 230 W TDP, the LX ULTRA has a 225 W TDP, a 5 W difference. Both cards require a 550 W suggested PSU. The B70 uses a single 8-pin power connector, while the LX ULTRA uses a single 16-pin connector.

The interface generation differs. The B70 runs on PCIe 5.0 x16, the LX ULTRA on PCIe 4.0 x16. For most graphics workloads this matters little, but data-transfer-heavy workloads that move buffers between system memory and VRAM could see a benefit from the newer PCIe generation on the B70.

The Verdict

The data indicates two cards with opposing strengths. The Intel Arc Pro B70 is the choice for rasterization-heavy tasks, high-resolution rendering, and memory-intensive workloads. Its 608.0 GB/s bandwidth, 358.4 GPixel/s pixel rate, and 716.8 GTexel/s texture rate dominate the LX ULTRA in every memory and fill-rate metric. The 32 GB VRAM capacity offers more headroom for large assets. The ray tracing cores provide a hardware feature the LX ULTRA does not list.

The Lisuan Tech LX ULTRA is the choice for raw compute throughput. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 outperform the B70, and the 6144 shading units give it a structural advantage in shader-bound workloads. The 24 GB VRAM is still substantial, and the 432.0 GB/s bandwidth is adequate, but it falls behind the B70 by 176.0 GB/s.

The database shows no benchmark scores for either card, so the verdict rests entirely on specification analysis. Neither card has accumulated measured performance data, and both sit at the 50th percentile against all GPUs by default. Buyers who prioritize fill rate, bandwidth, and RT hardware should look at the B70. Buyers who prioritize compute density in FP32 and FP16 should look at the LX ULTRA.

The B70 carries a launch MSRP of 949 USD. The LX ULTRA has no launch MSRP listed. Both cards are dual-slot designs with similar dimensions: the B70 is 267 mm long, 110 mm tall, and 39 mm wide; the LX ULTRA is 268 mm long, 112 mm tall, and 40 mm wide. The LX ULTRA is slightly longer, taller, and wider by 1 mm, 2 mm, and 1 mm respectively.
