Intel Arc Pro B370 vs Lisuan Tech LX ULTRA Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the Intel Arc Pro B370 against the Lisuan Tech LX ULTRA. Both entries show a percentile ranking of 50 against all GPUs, indicating they sit at the median of the recorded performance distribution, but this is not derived from direct comparative testing. The average benchmark score for both parts is zero, which means no validated workload results have been logged for either product at this time.

Without direct measurements, the raw compute specifications provide the only basis for comparing their output ceilings. The Lisuan Tech LX ULTRA delivers 24.58 TFLOPS of FP32 throughput, while the Intel Arc Pro B370 delivers 6.144 TFLOPS. The LX ULTRA therefore holds a 4x advantage in raw shader math, a figure derived directly from the recorded FP32 values. In FP16, the LX ULTRA reaches 49.15 TFLOPS against 12.29 TFLOPS for the Arc Pro B370, again a 4x margin, with both parts using a 2:1 ratio for FP16 to FP32 execution.

Pixel throughput shows a similar gap. The LX ULTRA produces 192.0 GPixel/s, while the Arc Pro B370 produces 48.00 GPixel/s, a 4x difference. Texture throughput follows the same pattern: 384.0 GTexel/s for the LX ULTRA versus 96.00 GTexel/s for the Arc Pro B370, another 4x spread. These ratios are consistent across every rate-based metric in the database, meaning the LX ULTRA is designed for a fundamentally higher throughput class.

The Intel part counters with a much lower power envelope. Its TDP of 25 W is one-ninth of the LX ULTRA's 225 W. That advantage does not appear in any performance score, but it defines the usable context for each product. The Arc Pro B370 is an integrated graphics processor with no power connectors and an IGP bus interface, while the LX ULTRA is a dual-slot discrete card requiring a 1x 16-pin connector and a 550 W suggested power supply.

Architecture Differences

The two GPUs come from different foundries and process nodes. Intel fabricates the Arc Pro B370 on a 3 nm node at Intel, using the Panther Lake chip with the Xe3-LPG architecture. Lisuan Tech builds the LX ULTRA on a 6 nm node at TSMC, using the 7G105 chip with the TrueGPU architecture. The Arc Pro B370 belongs to the Arc Graphics-WM (Panther Lake) generation, while the LX ULTRA belongs to the 7G100 generation.

Shader resources differ sharply. The LX ULTRA has 6144 shading units, 192 texture mapping units, and 96 raster output units. The Arc Pro B370 has 1280 shading units, 40 TMUs, and 20 ROPs. The LX ULTRA carries 4.8x the shading units, 4.8x the TMUs, and 4.8x the ROPs. The Arc Pro B370 does list 10 ray tracing cores, whereas the LX ULTRA entry records no ray tracing core count, leaving that capability unspecified in the database.

Memory architecture is entirely different. The LX ULTRA has 24 GB of GDDR6 memory on a 192-bit bus, with a bandwidth of 432.0 GB/s and a memory clock of 2250 MHz, listed as 18 Gbps effective. The Arc Pro B370 uses system shared memory with a system dependent bandwidth, no dedicated VRAM, and no fixed bus width. That distinction is central to how each part operates: the LX ULTRA has a fixed, private memory pool, while the Arc Pro B370 depends on the host system's memory subsystem.

API support overlaps on DirectX 12 Ultimate (12_2) and OpenGL 4.6, but diverges on Vulkan. The Arc Pro B370 supports Vulkan 1.4, while the LX ULTRA supports Vulkan 1.3. The LX ULTRA's display outputs are four DisplayPort 1.4a connectors; the Arc Pro B370's display outputs are listed as portable device dependent, reflecting its integrated nature.

Clock behavior is not directly comparable. The Arc Pro B370 has a base clock of 300 MHz and a boost clock of 2400 MHz. The LX ULTRA has no base or boost clock recorded in the database, so no frequency comparison is possible. The LX ULTRA's memory clock is the only fixed frequency listed for that part.

The LX ULTRA has physical dimensions of 268 mm length, 112 mm height, and 40 mm width, with a dual-slot cooler. The Arc Pro B370 has no dimensions recorded because it is an IGP integrated into a processor package.

Where Each One Wins

The Lisuan Tech LX ULTRA wins on every raw throughput metric recorded in the database. Its 24.58 TFLOPS FP32, 49.15 TFLOPS FP16, 192.0 GPixel/s pixel rate, and 384.0 GTexel/s texture rate place it far above the Arc Pro B370 in compute-heavy tasks. The 24 GB GDDR6 frame buffer with 432.0 GB/s bandwidth also gives it a decisive advantage for workloads that require large resident datasets, since the Arc Pro B370 must rely on system shared memory with bandwidth that varies by host configuration.

The Intel Arc Pro B370 wins on power efficiency and integration. At 25 W, it draws a small fraction of the LX ULTRA's 225 W. It requires no power connector, no expansion slot, and no separate memory purchase, because all memory resources are shared with the host. The Arc Pro B370 also supports Vulkan 1.4, a newer API revision than the LX ULTRA's Vulkan 1.3, which may matter for applications that target the latest Vulkan extensions.

The LX ULTRA is the only one of the two with a fixed memory bandwidth figure in the database, so any workload sensitivity to bandwidth favors it categorically. The Arc Pro B370's memory performance cannot be stated as a fixed number, only as system dependent.

The Arc Pro B370 includes 10 ray tracing cores, while the LX ULTRA has no ray tracing core count recorded. Whether the LX ULTRA implements ray tracing at all is not documented in the database, so the Arc Pro B370 holds the only confirmed ray tracing capability.

The Verdict

The database positions these two products in entirely different classes. The Lisuan Tech LX ULTRA is a high-throughput discrete GPU with 4x the FP32 compute, 4x the pixel rate, 4x the texture rate, and a dedicated 24 GB GDDR6 memory subsystem with 432.0 GB/s of bandwidth. It also has 4.8x the shading units, TMUs, and ROPs of the Intel part. Any workload that scales with raw shader throughput or memory bandwidth will favor the LX ULTRA by a wide margin.

The Intel Arc Pro B370 is an integrated GPU with a 25 W TDP, no power connectors, and system shared memory. It cannot match the LX ULTRA on any throughput metric in the database. Its advantages are structural: it consumes 200 W less power, requires no discrete card slot, and runs on the host's existing memory. It also carries the only confirmed ray tracing cores in this comparison, with 10 RT cores recorded, and supports Vulkan 1.4 against the LX ULTRA's Vulkan 1.3.

For a user selecting a discrete add-in card for maximum compute output, the LX ULTRA is the only viable option between these two. Its 24.58 TFLOPS FP32 and 24 GB frame buffer are the recorded figures that define its performance class. The Arc Pro B370 cannot be installed as a discrete card at all, since its bus interface is IGP.

For a system that needs graphics without a separate card, the Arc Pro B370 is the only option, because the LX ULTRA requires a PCIe 4.0 x16 slot, a dual-slot cooler, a 16-pin power connection, and a 550 W power supply. The Arc Pro B370's 25 W TDP and integrated design fit a portable or low-power platform, and its display outputs are portable device dependent, confirming that intended context.

Neither part has a recorded average benchmark score or head-to-head workload data, so the verdict rests entirely on specification comparison. The data indicates a clear performance hierarchy: the LX ULTRA dominates every compute and memory metric, while the Arc Pro B370 dominates power efficiency and integration. There is no scenario in the recorded data where the Arc Pro B370 outperforms the LX ULTRA on throughput, and no scenario where the LX ULTRA matches the Arc Pro B370's power draw or integrated form factor.
