Where Each One Wins

The RTX 5090 D V2 wins on raw compute and memory bandwidth. Its FP32 throughput of 104.8 TFLOPS is more than four times the LX MAX's 24.58 TFLOPS. Texture rate follows a similar pattern: 1,636.8 GTexel/s versus 384.0 GTexel/s. Pixel rate favors the RTX 5090 D V2 at 423.6 GPixel/s versus 192.0 GPixel/s. Memory bandwidth is 1.34 TB/s for the RTX 5090 D V2 against 432.0 GB/s for the LX MAX. For workloads that depend on parallel shading, texture fetching, or large memory transfers, the RTX 5090 D V2 dominates.

The LX MAX wins on power efficiency and physical footprint. Its TDP of 225 W is 350 W lower than the RTX 5090 D V2's 575 W, and its suggested PSU of 550 W is 400 W lower than the 950 W recommended for the RTX 5090 D V2. The LX MAX measures 248 mm in length and 118 mm in height, while the RTX 5090 D V2 measures 304 mm in length and 137 mm in height. Both cards are 48 mm wide and dual-slot, but the LX MAX is smaller in two of three dimensions. The LX MAX also supports FP16 at 49.15 TFLOPS with a 2:1 ratio, which is higher than its FP32 rate, while the RTX 5090 D V2 runs FP16 at 104.8 TFLOPS with a 1:1 ratio.

The LX MAX has no recorded benchmark wins because the database contains no benchmark entries for it. The RTX 5090 D V2 has one recorded benchmark result, and the head-to-head benchmark array between the two is empty, so no direct comparison of tested performance is available.

Architecture Differences

The RTX 5090 D V2 uses the GB202 chip built on the Blackwell 2.0 architecture from NVIDIA. It is manufactured by TSMC on a 5 nm process node with 92,200 million transistors on a 750 mm² die, yielding a transistor density of 122.9M per mm². The architecture includes 170 RT cores and 680 tensor cores, enabling dedicated ray tracing and AI acceleration. The card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Its production status is active, and it was released on 2025-08-14. The predecessor is listed as GeForce 40 and the successor as GeForce 60.

The LX MAX uses the 7G106 chip built on the TrueGPU architecture from Lisuan Tech. It is manufactured by TSMC on a 6 nm process node, but transistor count and die size are unknown. The architecture does not list RT cores or tensor cores, indicating no dedicated ray tracing or tensor hardware. The LX MAX supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.3, one version behind the RTX 5090 D V2 in Vulkan support. Its production status is active, and it was released on 2026-03-16. No predecessor or successor is listed.

The process node difference is 5 nm versus 6 nm, both from TSMC. The RTX 5090 D V2 has a much larger transistor count, but the LX MAX's transistor count is unknown, so a density comparison cannot be made. The RTX 5090 D V2 includes hardware ray tracing and tensor cores, while the LX MAX omits these from its specifications entirely. The API support differs only in Vulkan version: 1.4 for the RTX 5090 D V2, 1.3 for the LX MAX.

The two cards differ in nearly every major specification field. The RTX 5090 D V2 has a base clock of 2017 MHz and a boost clock of 2407 MHz; the LX MAX lists no base or boost clock. Memory clock differs: 1750 MHz (28 Gbps effective) for the RTX 5090 D V2 versus 2250 MHz (18 Gbps effective) for the LX MAX. Memory size is 24 GB versus 12 GB, type is GDDR7 versus GDDR6, bus width is 384 bit versus 192 bit, and bandwidth is 1.34 TB/s versus 432.0 GB/s.

Shading units are 21760 versus 6144, TMUs are 680 versus 192, and ROPs are 176 versus 96. The RTX 5090 D V2 has 170 RT cores and 680 tensor cores; the LX MAX has none listed. Pixel rate is 423.6 GPixel/s versus 192.0 GPixel/s, texture rate is 1,636.8 GTexel/s versus 384.0 GTexel/s, and FP32 is 104.8 TFLOPS versus 24.58 TFLOPS.

TDP is 575 W versus 225 W, suggested PSU is 950 W versus 550 W, and bus interface is PCIe 5.0 x16 versus PCIe 4.0 x16. Display outputs are 1x HDMI 2.1b plus 3x DisplayPort 2.1b versus 4x DisplayPort 1.4a. Dimensions are 304 mm by 137 mm by 48 mm versus 248 mm by 118 mm by 48 mm. The RTX 5090 D V2 has a launch MSRP of 2,299 USD; the LX MAX has no launch MSRP listed. Release dates are 2025-08-14 versus 2026-03-16. The RTX 5090 D V2 has a predecessor and successor, while the LX MAX has neither.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for the RTX 5090 D V2 and the LX MAX. The headToHeadBenchmarks array is empty, and the wins counter shows 0 for both cards. The only benchmark score available is the RTX 5090 D V2's 3DMark Steel Nomad DX12 result of 16504. The LX MAX has zero benchmark scores, so its average benchmark score is 0.

The RTX 5090 D V2's single score of 16504 places it in the 59th percentile among all GPUs. Its nearest rival, the NVIDIA T400, scores 16508 with a delta of 0%, meaning the RTX 5090 D V2 is statistically tied with the T400 in the database's recorded results. The AMD Radeon PRO W7500 is 0.5% behind with a score of 16415, the NVIDIA RTX PRO 6000 Blackwell is 0.6% behind with 16408, and the AMD Radeon RX 5700 XT is 0.9% behind with 16361. These deltas are all under 1%, indicating that the RTX 5090 D V2's measured performance is essentially identical to a group of cards that are far below its specification tier.

The LX MAX has no nearest rivals listed and no benchmark results, so no performance comparisons can be drawn from the database. The absence of benchmark data for the LX MAX means that any analysis of its real-world speed is unavailable. The recorded data shows the RTX 5090 D V2 as a tested, scored product, while the LX MAX exists in the database only through its specifications.

The Verdict

The RTX 5090 D V2 is the clear choice for any workload that requires maximum compute throughput. Its FP32 output of 104.8 TFLOPS, texture rate of 1,636.8 GTexel/s, and pixel rate of 423.6 GPixel/s are all far above the LX MAX's corresponding figures of 24.58 TFLOPS, 384.0 GTexel/s, and 192.0 GPixel/s. Memory bandwidth of 1.34 TB/s versus 432.0 GB/s gives the RTX 5090 D V2 a decisive advantage in data-heavy tasks. The inclusion of 170 RT cores and 680 tensor cores provides dedicated hardware that the LX MAX lacks entirely.

The LX MAX is the appropriate pick for systems with strict power or space constraints. Its 225 W TDP and 550 W suggested PSU make it far less demanding than the RTX 5090 D V2's 575 W TDP and 950 W suggested PSU. Its smaller dimensions of 248 mm by 118 mm by 48 mm fit into cases where the RTX 5090 D V2's 304 mm by 137 mm by 48 mm footprint will not. The LX MAX's FP16 rate of 49.15 TFLOPS (2:1) shows that it can double its FP32 throughput in mixed-precision workloads, though its absolute FP16 output is still less than half of the RTX 5090 D V2's 104.8 TFLOPS (1:1).

The benchmark data does not support a performance verdict for the LX MAX, as it has no recorded scores. The RTX 5090 D V2's score of 16504 places it in the 59th percentile, but its nearest rivals are all within 0.9% of that score. Users who prioritize tested performance should select the RTX 5090 D V2. Users who prioritize low power draw and compact size should select the LX MAX. The two cards serve different purposes: one is a high-throughput flagship with extensive memory and compute resources, and the other is a modest, efficient card with a lower specification ceiling.
