Lisuan Tech LX MAX vs Lisuan Tech LX ULTRA Comparison

Where Each One Wins

The Lisuan Tech LX MAX and Lisuan Tech LX ULTRA share the same underlying compute architecture, and the recorded data confirms that neither card has a performance advantage in raw processing throughput. Both deliver identical shading unit counts, identical texture and pixel rates, and identical floating-point throughput. The benchmark results show a split with zero wins for either card, which means the two models are functionally equivalent in compute-bound workloads.

The LX MAX distinguishes itself through its physical footprint. At 248 mm in length, 118 mm in height, and 48 mm in width, it is the shorter and thicker of the two cards. This makes it the better fit for compact chassis where length is the limiting factor. The LX ULTRA, by contrast, extends to 268 mm in length but reduces height to 112 mm and width to 40 mm. The ULTRA is a longer, slimmer card, which may suit cases with ample horizontal clearance but tighter vertical or slot spacing.

The decisive differentiator in the database is memory capacity. The LX MAX carries 12 GB of GDDR6, while the LX ULTRA carries 24 GB of GDDR6. Both use a 192-bit memory bus and achieve identical bandwidth of 432.0 GB/s. The ULTRA therefore doubles the frame buffer without changing memory speed or bus width. For workloads that consume more than 12 GB of video memory, such as large texture sets, high-resolution rendering, or multi-model machine learning inference, the ULTRA is the only viable choice between the two.

In terms of power delivery, both cards draw a 225 W TDP, use a single 16-pin power connector, and recommend a 550 W power supply. Neither card requires a larger PSU than the other. The display output configuration is also identical, with four DisplayPort 1.4a connections on each card. The API support matches as well, with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3 on both.

FAQ

Head-to-Head Benchmarks

The head-to-head benchmark table in the database contains no entries, and the win counts for both cards are zero. This is an unusual but clear result: neither card outperforms the other in any measured workload. The reason is visible in the specification comparison. Both cards use the same 7G106 and 7G105 chips respectively, but the compute blocks are identical in count and configuration. Shading units, TMUs, ROPs, pixel rate, texture rate, FP32, and FP16 are all exact matches.

The only numerical differences between the two cards are memory capacity and physical dimensions. The LX ULTRA doubles the memory from 12 GB to 24 GB, but this does not change the bandwidth, because the bus width and memory clock remain constant. The LX MAX and LX ULTRA both achieve 432.0 GB/s, so memory-bound workloads that fit within 12 GB will run at the same speed on either card. Workloads that exceed 12 GB will not run on the LX MAX at all, which gives the ULTRA a functional win in those scenarios, but the database records no benchmark win because the comparison is limited to identical workloads that both cards can complete.

The percentile ranking also confirms the equivalence: both cards sit at the 50th percentile against all GPUs in the database. The average benchmark score is zero for both, which aligns with the empty benchmark list. There are no nearest rivals listed for either card, so no external comparison data is available. The practical takeaway from the head-to-head data is that the LX MAX and LX ULTRA are interchangeable in terms of raw speed, and the choice between them hinges entirely on memory capacity and physical fit.

Specification Differences

The specification tables for the two cards differ in exactly four fields: memory size, length, height, and width. The LX MAX has 12 GB of GDDR6, while the LX ULTRA has 24 GB. The LX MAX measures 248 mm by 118 mm by 48 mm, while the LX ULTRA measures 268 mm by 112 mm by 40 mm. All other listed specifications are identical.

Memory type is GDDR6 on both cards. The bus width is 192 bit on both. The memory clock is 2250 MHz with 18 Gbps effective speed on both. Bandwidth is 432.0 GB/s on both. The chip names differ, 7G106 for the MAX and 7G105 for the ULTRA, but the compute configuration does not change. Shading units, TMUs, ROPs, pixel rate, texture rate, FP32, and FP16 are all the same numbers on both pages.

The power specifications match exactly. TDP is 225 W on both. The power connector is one 16-pin on both. The suggested PSU is 550 W on both. The slot width is dual-slot on both. The bus interface is PCIe 4.0 x16 on both. Display outputs are four DisplayPort 1.4a on both. The API support list is identical, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3.

The production status is Active for both cards, and the release date is the same, 2026-03-16. Neither card has a launch MSRP listed, so no pricing information is available in the database. The process node is 6 nm at TSMC for both, with unknown transistor counts and die sizes. Neither card has a codename, predecessor, or successor listed.

Architecture Differences

Both the LX MAX and LX ULTRA are built on the TrueGPU architecture, belonging to the 7G100 generation. The process node is 6 nm at TSMC for both cards. The transistor count and die size are listed as unknown for both, so no die-level comparison is possible from the recorded data.

The chip identifiers differ: the LX MAX uses the 7G106 chip, while the LX ULTRA uses the 7G105 chip. The database does not provide details on what these chip names signify beyond the compute block counts, which are identical. The shading unit count is 6144 on both, the TMU count is 192 on both, and the ROP count is 96 on both. The pixel rate of 192.0 GPixel/s and the texture rate of 384.0 GTexel/s are the same on both cards.

Neither card lists ray tracing cores or tensor cores, so the architecture does not appear to include dedicated hardware for those functions beyond what is integrated into the shading units. The FP32 throughput is 24.58 TFLOPS on both, and the FP16 throughput is 49.15 TFLOPS with a 2:1 ratio on both. The absence of a clock speed listing for base or boost means the frequency behavior is not recorded in the database, but the measured throughput values are consistent across both cards.

The memory subsystem is architecturally identical except for capacity. Both use GDDR6 on a 192-bit bus, running at 2250 MHz with 18 Gbps effective speed. The bandwidth is 432.0 GB/s on both. The ULTRA simply doubles the number of memory chips or the density per chip, without altering the bus or clock. This means memory latency characteristics should be similar, and the only difference is how much data can reside in the frame buffer.

The physical design differs in dimensions, but the slot width and power connector layout are the same. Both cards are dual-slot, both use a single 16-pin connector, and both require a 550 W PSU. The longer ULTRA board may accommodate more memory modules, which explains the 24 GB capacity, but the database does not provide a die or board photo to confirm this.

The Verdict

The recorded data indicates that the Lisuan Tech LX MAX and Lisuan Tech LX ULTRA are identical in compute performance. Every measurable throughput figure, from shading units to FP32 TFLOPS, is the same. The head-to-head benchmark table is empty, and the win count is zero for both cards. Users who need raw processing speed will find no difference between the two.

The LX ULTRA is the correct choice when memory capacity is the priority. Its 24 GB frame buffer is double the LX MAX's 12 GB, and this is the only specification that separates the two in terms of workload capability. Applications that require more than 12 GB of video memory, such as very high-resolution textures, large batch inference, or multi-stream rendering, will only run on the ULTRA. The bandwidth remains the same at 432.0 GB/s, so the ULTRA does not move data faster, but it can hold more of it.

The LX MAX is the correct choice when physical space is constrained. At 248 mm long, it is 20 mm shorter than the ULTRA, and it is also taller and thicker. The MAX may fit into cases where the ULTRA's 268 mm length is too long. The MAX also offers the full 12 GB frame buffer, which is sufficient for many standard gaming and rendering workloads, and it delivers the same 24.58 TFLOPS of FP32 performance as the ULTRA.

For users with no memory capacity concerns and no case clearance issues, the two cards are functionally interchangeable. The power draw, connector, PSU recommendation, display outputs, and API support are all identical. The choice reduces to a simple trade-off: more memory on the ULTRA versus a shorter board on the MAX. The database shows no other meaningful distinction, and the 50th percentile ranking for both cards confirms that they sit at the same level in the overall GPU landscape.
