Architecture Differences

The RTX 3080 Mobile is built on the GA104 chip using the Ampere architecture, manufactured on an 8 nm process at Samsung. In contrast, the Quadro M4000M uses the GM204 chip with the Maxwell 2.0 architecture, fabricated on a 28 nm process at TSMC. The process node gap is significant: 8 nm versus 28 nm, which directly influences transistor density and power efficiency.

Transistor counts tell a similar story. The GA104 packs 17,400 million transistors on a 392 mm² die, yielding a density of 44.4 million transistors per mm². The GM204 has 5,200 million transistors on a slightly larger 398 mm² die, giving a density of just 13.1 million per mm². The RTX 3080 Mobile has over three times the transistor density, which explains its ability to deliver far higher compute throughput despite a modest TDP increase (115 W versus 100 W).

The RTX 3080 Mobile adds hardware features that the Quadro M4000M entirely lacks. It includes 48 ray tracing cores and 192 tensor cores, both absent from the Maxwell part. This means the RTX 3080 Mobile supports hardware-accelerated ray tracing and AI-based tensor operations, while the Quadro M4000M must rely on older, non-accelerated paths for those workloads. The API support also differs: the RTX 3080 Mobile reaches DirectX 12 Ultimate (12_2), whereas the Quadro M4000M tops out at DirectX 12 (12_1).

Memory architecture is another major divergence. The RTX 3080 Mobile uses GDDR6 at 14 Gbps effective, delivering 448.0 GB/s over a 256-bit bus. The Quadro M4000M uses GDDR5 at 5 Gbps effective, delivering 160.4 GB/s over the same bus width. That is a 2.8x bandwidth advantage for the newer card. The RTX 3080 Mobile also doubles the frame buffer to 8 GB, which matters for large textures and compute datasets.

The bus interface differs as well: the RTX 3080 Mobile runs PCIe 4.0 x16, while the Quadro M4000M uses PCIe 3.0 x16. The older card also comes in an MXM Module form factor, whereas the RTX 3080 Mobile has no specified slot width, indicating a soldered or custom mobile design. Both cards share the same display output behavior: portable device dependent.

Where Each One Wins

The RTX 3080 Mobile wins every recorded benchmark in the shared test set. In Geekbench OpenCL, it scores 104831 against 19989, a 424.4% lead. In Geekbench Vulkan, it scores 104066 against 20971, a 396.2% lead. These are not marginal victories; they are generational leaps.

For raw compute workloads, the RTX 3080 Mobile is the clear choice. Its FP32 throughput is 18.98 TFLOPS versus 2.593 TFLOPS for the Quadro M4000M, a 7.3x difference. Texture rate is 296.6 GTexel/s versus 81.04 GTexel/s, and pixel rate is 148.3 GPixel/s versus 64.83 GPixel/s. Any task that relies on shader math, texture filtering, or pixel fill will favor the RTX 3080 Mobile by a wide margin.

The Quadro M4000M’s only potential advantage lies in its legacy position. With a 65th percentile ranking and an average score of 20480, it sits close to the RTX 3070 Mobile (delta -0.3%) and the Intel Arc B570 (delta -0.4%). For systems where the MXM Module form factor is mandatory, the Quadro M4000M remains a drop-in option. But the data shows no performance scenario where it beats the RTX 3080 Mobile.

Head-to-Head Benchmarks

The shared benchmark suite between these two GPUs consists of only two tests: Geekbench OpenCL and Geekbench Vulkan. Both show overwhelming wins for the RTX 3080 Mobile.

In Geekbench OpenCL, the RTX 3080 Mobile records 104831 points. The Quadro M4000M records 19989 points. The delta is 424.4%. This test stresses general-purpose compute across multiple backends, and the results reflect the architectural gulf. The RTX 3080 Mobile’s 6144 shading units and 192 tensor cores provide a massive parallel throughput advantage over the Quadro M4000M’s 1280 shading units. The newer card also has 448.0 GB/s of memory bandwidth to feed those cores, versus 160.4 GB/s for the older part.

In Geekbench Vulkan, the RTX 3080 Mobile scores 104066, while the Quadro M4000M scores 20971, a delta of 396.2%. Vulkan is a low-level graphics and compute API; the RTX 3080 Mobile’s support for DirectX 12 Ultimate features and its hardware ray tracing cores likely contribute to its ability to handle modern workloads more efficiently. The Quadro M4000M, despite supporting Vulkan 1.4, lacks the hardware features that the Ampere architecture brings.

The RTX 3080 Mobile’s other benchmark results, though not directly compared head-to-head, contextualize its standing. Its Passmark G3D score is 16321, and its Passmark GPU Compute score is 7276. The Geekbench scores align with these: the card is consistently strong across DirectX and compute tests. The Quadro M4000M, by contrast, has no recorded Passmark results in the database, so its average score of 20480 relies entirely on the two Geekbench entries.

Nearest rival data adds perspective. The RTX 3080 Mobile’s average score of 23628 puts it 0.5% above the RTX 3070 Ti Mobile and 1.3% above the AMD Radeon AI PRO R9700. It sits 1% below the AMD Radeon RX 9070. The Quadro M4000M’s average of 20480 is 0.3% below the RTX 3070 Mobile and 0.5% below the Intel Arc A750. Both cards are tightly clustered with their peers, but the clusters are far apart.

The Verdict

The data is unambiguous. The RTX 3080 Mobile outperforms the Quadro M4000M in every recorded benchmark, with deltas exceeding 390% in both OpenCL and Vulkan. Its average score of 23628 versus 20480 places it in a different performance tier, and its 69th percentile ranking versus 65th confirms the gap.

For users prioritizing compute performance, especially in OpenCL or Vulkan workloads, the RTX 3080 Mobile is the only rational choice from this comparison. Its FP32 throughput of 18.98 TFLOPS, 8 GB of GDDR6 memory, and 448.0 GB/s bandwidth provide the resources needed for modern applications. The Quadro M4000M’s 2.593 TFLOPS and 4 GB of GDDR5 simply cannot compete.

The Quadro M4000M’s case rests entirely on its MXM Module form factor. In systems that require that specific physical standard, the RTX 3080 Mobile may not fit. But purely on performance data, the older card trails by a wide margin. Its nearest rivals, such as the RTX 3070 Mobile and Intel Arc A750, all sit within 1% of its average score, confirming that it is a competent mid-range part, not a high-end one.

The verdict: choose the RTX 3080 Mobile if performance is the sole criterion. Choose the Quadro M4000M only if the hardware form factor or legacy system compatibility overrides the substantial performance deficit. For any new build or upgrade where both cards are physically viable, the RTX 3080 Mobile wins decisively.
