NVIDIA GeForce MX350 vs NVIDIA Quadro P4000 Comparison

The Verdict

The recorded data presents a decisive outcome: the NVIDIA Quadro P4000 wins every head-to-head benchmark against the GeForce MX350. In the two shared tests, the P4000 leads by 76% in Geekbench OpenCL and 68.7% in Geekbench Vulkan. The MX350 does not win a single recorded comparison. For users choosing between these two, the P4000 is the clear pick for any compute or graphics workload measured in the database. The MX350, however, occupies a different niche entirely. Its 20 W TDP and lack of power connectors point to portable device integration, while the P4000 is a single-slot, 105 W card requiring a 6-pin connector and a 300 W suggested PSU. The MX350 is for thin-and-light laptops where space and power are constrained; the P4000 is for desktop workstations where performance takes priority. Benchmarks indicate the P4000 delivers roughly four times the OpenCL score and over three times the Vulkan score of the MX350. There is no scenario in the recorded data where the MX350 outperforms the P4000.

Architecture Differences

Both GPUs share the Pascal architecture, but they diverge sharply in nearly every physical and functional attribute. The MX350 uses the GP107S chip built on Samsung's 14 nm process, with 3,300 million transistors on a 132 mm² die. The P4000 uses the GP104 chip fabricated by TSMC on a 16 nm process, with 7,200 million transistors on a 314 mm² die. The transistor density is similar, 25.0M per mm² for the MX350 versus 22.9M per mm² for the P4000, but the P4000 simply has more than twice the silicon area and more than double the transistor count.

The compute configuration scales accordingly. The MX350 has 640 shading units, 32 texture mapping units, and 16 ROPs. The P4000 has 1792 shading units, 112 TMUs, and 64 ROPs. That is 2.8 times the shader count, 3.5 times the TMUs, and 4 times the ROPs. Neither card has ray tracing cores or tensor cores. Both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The P4000 lists a predecessor in Quadro Maxwell and a successor in Quadro Volta, while the MX350 has no listed predecessor or successor.

Memory architecture is another major divider. The MX350 has 2 GB of GDDR5 on a 64-bit bus, delivering 56.06 GB/s of bandwidth. The P4000 has 8 GB of GDDR5 on a 256-bit bus, delivering 243.3 GB/s. The memory clock differs slightly: 1752 MHz (7 Gbps effective) for the MX350 versus 1901 MHz (7.6 Gbps effective) for the P4000. The bus width is the dominant factor, giving the P4000 over four times the memory bandwidth.

Where Each One Wins

Based strictly on the recorded benchmark wins, the P4000 wins all shared tests. The MX350 has zero wins in the head-to-head data. That does not mean the MX350 is without purpose; its specifications point to a different class of device. The 20 W TDP, PCIe 3.0 x4 interface, and "Portable Device Dependent" display outputs suggest it is designed for mobile systems where power draw is critical. The P4000, with its 105 W TDP, single-slot profile, 241 mm length, 111 mm height, and four DisplayPort 1.4a outputs, is built for desktop workstations with dedicated PCIe 3.0 x16 slots.

For workload split, the P4000 dominates compute-oriented tasks. Its Geekbench OpenCL score of 36212 versus the MX350's 8689 indicates a 316% advantage in general-purpose GPU compute. In Vulkan, the P4000 scores 41786 versus 13077, a 219% advantage. The P4000 also has additional recorded data: 3DMark Steel Nomad DX12 at 1115, Passmark G3D at 11466, Passmark GPU Compute at 4913, and several DirectX-specific Passmark scores. The MX350 has no recorded data in those tests, so the database shows no basis for the MX350 winning any of those workloads.

The MX350's advantage is not measured in performance but in integration flexibility. It requires no power connectors, which means it can be placed in systems without the thermal headroom for a 6-pin connector. Its 64-bit memory bus limits total bandwidth to 56.06 GB/s, which is sufficient for lighter graphical tasks. The P4000's larger footprint and power requirements disqualify it from such compact environments.

Head-to-Head Benchmarks

The database contains two direct head-to-head comparisons, and the P4000 wins both by substantial margins. In Geekbench OpenCL, the P4000 scores 36212 against the MX350's 8689. The delta is 76% in favor of the P4000, meaning the P4000 delivers more than four times the raw compute score. This is the largest gap in the shared test set and reflects the difference in shading units, TMUs, ROPs, and memory bandwidth. The MX350's 640 shading units and 56.06 GB/s bandwidth are simply outmatched by the P4000's 1792 shading units and 243.3 GB/s.

In Geekbench Vulkan, the P4000 scores 41786 versus 13077 for the MX350, a delta of 68.7%. The proportional gap is slightly smaller than OpenCL, but the absolute difference is still massive. The P4000's Vulkan score is over three times the MX350's. The MX350's nearest rival data shows it performs near the GeForce GTX 1650 SUPER, which scores 11047, just 1.5% above the MX350. The P4000's rivals sit much lower in average score, with the closest being the AMD Radeon Pro WX 2100 at 9653, a 0.1% difference. This places the P4000 in a performance tier where its average benchmark of 9665 is dragged down by additional tests that the MX350 does not take.

The P4000 has additional benchmark results that are not shared with the MX350. In 3DMark Steel Nomad DX12, it scores 1115. In Passmark, it records 66 in DirectX 10, 86 in DirectX 11, 40 in DirectX 12, 181 in DirectX 9, 786 in G2D, 11466 in G3D, and 4913 in GPU Compute. These scores show a card that is capable across a wide range of API generations, with G3D significantly outperforming G2D. The MX350 has no recorded scores in these tests, so no direct comparison is possible, but the absence of data means the P4000 is the only one of the two with verified performance in those workloads.

Specification Differences

The two cards differ in every major specification category. The process node differs: 14 nm Samsung for the MX350 versus 16 nm TSMC for the P4000. Transistor count is 3,300 million for the MX350 versus 7,200 million for the P4000. Die size is 132 mm² versus 314 mm². Transistor density is 25.0M per mm² for the MX350 and 22.9M per mm² for the P4000.

Clock speeds differ modestly. The MX350 has a base clock of 1354 MHz and a boost of 1468 MHz. The P4000 has a base of 1202 MHz and a boost of 1480 MHz. The MX350 actually has a higher base clock, but the P4000 slightly edges it in boost. Memory clocks are close: 1752 MHz (7 Gbps effective) for the MX350 versus 1901 MHz (7.6 Gbps effective) for the P4000.

Memory capacity and interface differ greatly. The MX350 has 2 GB of GDDR5 on a 64-bit bus. The P4000 has 8 GB on a 256-bit bus. Bandwidth is 56.06 GB/s versus 243.3 GB/s. The MX350 uses a PCIe 3.0 x4 interface, while the P4000 uses PCIe 3.0 x16. Display outputs are "Portable Device Dependent" for the MX350, while the P4000 offers 4x DisplayPort 1.4a.

Physical and power specifications diverge as well. The MX350 has a 20 W TDP, no power connectors, and no listed dimensions. The P4000 has a 105 W TDP, a single-slot profile, one 6-pin power connector, a 300 W suggested PSU, and dimensions of 241 mm length and 111 mm height. The MX350 has no listed length, height, or width. The P4000 is the only one with a listed predecessor (Quadro Maxwell) and successor (Quadro Volta).
