A: Both GPUs feature 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s bandwidth and 2250 MHz memory clock (18 Gbps effective). The memory subsystem is identical in capacity, type, bus width, and bandwidth.

Q: Which GPU has higher raw compute throughput?

A: The LX MAX delivers 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 (2:1 ratio), while the RTX 4080 Max-Q delivers 20.04 TFLOPS FP32 and 20.04 TFLOPS FP16 (1:1 ratio). The LX MAX leads in both metrics, with a substantial advantage in FP16 throughput.

Q: What are the power and physical specifications of each GPU?

A: The RTX 4080 Max-Q has a 60 W TDP, uses an IGP slot width, has no power connectors, and is portable device dependent for display outputs. The LX MAX has a 225 W TDP, uses a dual-slot design with a 1x 16-pin power connector, requires a 550 W suggested PSU, and offers 4x DisplayPort 1.4a outputs.

Q: Which GPU has higher pixel and texture fill rates?

A: The LX MAX achieves 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate, compared to the RTX 4080 Max-Q's 108.0 GPixel/s and 313.2 GTexel/s. The LX MAX leads by 84.0 GPixel/s in pixel throughput and 70.8 GTexel/s in texture throughput.

Q: What API support differences exist between the two GPUs?

A: Both support DirectX 12 Ultimate (12_2) and OpenGL 4.6. The RTX 4080 Max-Q supports Vulkan 1.4, while the LX MAX supports Vulkan 1.3. The RTX 4080 Max-Q also includes 58 RT cores and 232 tensor cores, whereas the LX MAX has no listed RT or tensor core counts.

Architecture Differences

The architectural split between these two GPUs is pronounced. The NVIDIA GeForce RTX 4080 Max-Q is built on Ada Lovelace, a generation that incorporates dedicated ray tracing hardware and tensor cores for AI acceleration. The chip, AD104, is fabricated on a 5 nm TSMC process and contains 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². The LX MAX, by contrast, uses the TrueGPU architecture with the 7G106 chip on a 6 nm TSMC process. Its transistor count and die size are not recorded in the database.

The compute resource distribution differs significantly. The RTX 4080 Max-Q fields 7424 shading units, 232 texture mapping units, and 80 render output units. The LX MAX counters with 6144 shading units, 192 TMUs, and 96 ROPs. This means the RTX 4080 Max-Q has 1280 more shading units and 40 more TMUs, yet the LX MAX has 16 more ROPs. The RTX 4080 Max-Q also carries 58 RT cores and 232 tensor cores, features absent from the LX MAX's specification sheet, which lists no RT or tensor core counts.

The FP16 compute ratio marks a fundamental design divergence. The RTX 4080 Max-Q runs FP16 at a 1:1 ratio with FP32, both at 20.04 TFLOPS, suggesting a unified compute path. The LX MAX runs FP16 at a 2:1 ratio, delivering 49.15 TFLOPS FP16 versus 24.58 TFLOPS FP32, indicating a doubled-rate half-precision path. This is typical of architectures that prioritize mixed-precision workloads where FP16 throughput matters more than FP32 parity.

Clock behavior also differs. The RTX 4080 Max-Q has recorded base and boost clocks of 795 MHz and 1350 MHz respectively, reflecting its low-power Max-Q design. The LX MAX has no base or boost clock listed, so its clock strategy remains unspecified in the database. The memory clock is identical: 2250 MHz with 18 Gbps effective for both.

Physical implementation separates the two further. The RTX 4080 Max-Q is an IGP (integrated graphics processor) with no power connectors and a 60 W TDP, aimed at portable devices where display outputs are device-dependent. The LX MAX is a dual-slot discrete card measuring 248 mm in length, 118 mm in height, and 48 mm in width, with a 1x 16-pin power connector and a 225 W TDP. The suggested PSU for the LX MAX is 550 W.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs, and both have zero average benchmark scores with 50th percentile standings against all GPUs. The comparison must therefore rest on the recorded specification-derived throughput metrics.

The LX MAX dominates in raw computational throughput. In FP32, it delivers 24.58 TFLOPS against the RTX 4080 Max-Q's 20.04 TFLOPS, a lead of 4.54 TFLOPS or approximately 22.7% higher. In FP16, the gap widens dramatically: the LX MAX's 49.15 TFLOPS is more than double the RTX 4080 Max-Q's 20.04 TFLOPS, representing a 145.2% advantage. This is the single largest performance differential between the two products.

Fill rate comparisons follow a similar pattern. The LX MAX achieves 192.0 GPixel/s pixel rate versus 108.0 GPixel/s for the RTX 4080 Max-Q, a difference of 84.0 GPixel/s, or 77.8% higher. Texture rate shows a narrower margin: 384.0 GTexel/s for the LX MAX against 313.2 GTexel/s for the RTX 4080 Max-Q, a 70.8 GTexel/s lead, or 22.6% higher.

The RTX 4080 Max-Q does not lead in any of the recorded compute or fill rate metrics. Its advantages lie elsewhere: RT cores and tensor cores provide dedicated hardware paths that the LX MAX does not list, and its 1:1 FP16 ratio may offer consistent precision behavior across workloads. The Vulkan 1.4 support on the RTX 4080 Max-Q is a generation ahead of the LX MAX's Vulkan 1.3.

Pixel rate analysis reveals an interesting inversion. The RTX 4080 Max-Q has 80 ROPs and achieves 108.0 GPixel/s, while the LX MAX has 96 ROPs and achieves 192.0 GPixel/s. The LX MAX's per-ROP output is 2.0 GPixel/s versus the RTX 4080 Max-Q's 1.35 GPixel/s, indicating the LX MAX's ROPs operate at a substantially higher effective rate, consistent with its higher power envelope and potentially higher clock speeds.

Texture rate per TMU shows the LX MAX at 2.0 GTexel/s per TMU (384.0 divided by 192) versus the RTX 4080 Max-Q at 1.35 GTexel/s per TMU (313.2 divided by 232). The LX MAX's TMUs are more efficient per unit, though the RTX 4080 Max-Q has more of them.

All other fields differ or are unrecorded for one side.

Where Each One Wins

The LX MAX wins decisively in raw compute throughput. Its 24.58 TFLOPS FP32 and 49.15 TFLOPS FP16 make it the stronger choice for workloads that saturate shader units, such as compute-heavy rendering, scientific simulation, or FP16-accelerated inference. The 192.0 GPixel/s pixel rate and 384.0 GTexel/s texture rate further reinforce its advantage in fill-limited scenarios, where rasterization and texture sampling dominate. The dual-slot form factor with 4x DisplayPort 1.4a outputs and a dedicated 16-pin power connector indicates a product designed for stationary desktop use with multi-monitor setups. Its 225 W TDP and 550 W suggested PSU confirm that it expects a robust power delivery system.

The RTX 4080 Max-Q wins in efficiency and integrated feature support. Its 60 W TDP is 165 W lower than the LX MAX, making it suitable for portable devices where power budgets are constrained. The IGP slot width and absence of power connectors mean it can be soldered directly onto a motherboard without external cabling. The presence of 58 RT cores and 232 tensor cores provides dedicated hardware for ray tracing and AI operations, features the LX MAX does not list. Vulkan 1.4 support gives it a newer API baseline than the LX MAX's Vulkan 1.3. The 1:1 FP16 ratio ensures that half-precision workloads do not receive a different throughput profile than FP32, which may benefit applications expecting consistent precision scaling.

The RTX 4080 Max-Q's lower clock speeds (795 MHz base, 1350 MHz boost) reflect a conservative power design, yet its higher shading unit count (7424 versus 6144) partially compensates. The transistor density of 121.8M per mm² on a 5 nm node indicates a denser, more advanced manufacturing process compared to the LX MAX's 6 nm node. The LX MAX's unknown transistor count and die size prevent a direct density comparison.

For real-world usage, the LX MAX is the performance leader in every measured compute and fill rate category. Applications that can utilize its FP16 throughput will see the largest gains, with a 145.2% advantage over the RTX 4080 Max-Q. Applications bound by pixel output will benefit from the 77.8% higher pixel rate. Texture-bound workloads gain 22.6%. The RTX 4080 Max-Q, however, offers a complete feature set for ray tracing and tensor workloads, plus a power profile that enables deployment in thin-and-light systems. Its lack of a launch MSRP in the database means no pricing comparison is possible.

The release dates place the RTX 4080 Max-Q in early 2023 and the LX MAX in early 2026, a three-year gap that may explain the LX MAX's higher clock-independent throughput metrics. The RTX 4080 Max-Q's predecessor is the GeForce 30 Mobile and its successor is the GeForce 50 Mobile, placing it in a defined product lineage. The LX MAX has no recorded predecessor or successor, marking it as a standalone entry in the 7G100 generation.
