NVIDIA GeForce GTX 675MX vs NVIDIA Quadro P4000 Comparison

The data places the NVIDIA Quadro P4000 and the NVIDIA GeForce GTX 675MX at opposite ends of the GPU timeline, with the P4000 holding a decisive advantage in the recorded metrics. The Quadro P4000, a professional Pascal-generation part, posts an average benchmark score of 9665, placing it in the 47th percentile of all GPUs. The GTX 675MX, a Kepler-generation mobile part, averages 8427, placing it in the 43rd percentile. The 1238-point gap in average scores reflects a generational leap in compute capability, but the recorded data also reveals specific strengths and architectural divergences that define where each card fits.

Head-to-Head Benchmarks

The only direct benchmark comparison recorded between these two GPUs is the Geekbench OpenCL test, and the result is overwhelmingly in favor of the Quadro P4000. The P4000 scores 36212, while the GTX 675MX scores 10723. This represents a 237.7% delta, meaning the Quadro P4000 delivers more than triple the raw compute performance in this OpenCL workload. This is not a marginal win; it is a dominant performance gap that underscores the architectural and process-node advantages held by the newer card.

The magnitude of this delta is striking when considered against the rivals listed in the database. The Quadro P4000’s nearest rival, the AMD Radeon Pro WX 2100, scores 9653, a delta of just 0.1%. The NVIDIA GeForce GTX 960M scores 9645, a 0.2% delta, and the NVIDIA Quadro K5000 scores 9637, a 0.3% delta. The only rival with a higher average score is the NVIDIA Tesla C2070 at 9716, a -0.5% delta relative to the P4000. In contrast, the GTX 675MX’s nearest rivals are tightly clustered: the AMD Radeon 880M scores 8436 (-0.1%), the NVIDIA GeForce MX330 scores 8458 (-0.4%), the AMD Radeon HD 8870M scores 8462 (-0.4%), and the AMD Radeon R9 M375X scores 8325 (1.2%). The P4000 sits near the top of its immediate peer group, while the GTX 675MX sits near the bottom of its own, and the head-to-head OpenCL result shows just how wide that separation can become.

The Quadro P4000 also holds the win count in the recorded head-to-head benchmarks, taking 1 win to the GTX 675MX’s 0. Beyond the OpenCL test, the P4000’s benchmark suite includes results from 3DMark Steel Nomad DX12 (1115), Geekbench Vulkan (41786), Passmark DirectX 10 (66), DirectX 11 (86), DirectX 12 (40), DirectX 9 (181), G2D (786), G3D (11466), and GPU Compute (4913). The GTX 675MX only has two recorded benchmarks: Geekbench Metal (6131) and Geekbench OpenCL (10723). The absence of overlapping tests beyond OpenCL means the head-to-head comparison is limited, but the one available data point is unambiguous: the P4000 outperforms the GTX 675MX by a wide margin in a compute-heavy workload.

Where Each One Wins

The Quadro P4000 wins in every measurable category where both cards have recorded data. The OpenCL result is the headline, but the P4000’s broader benchmark profile shows consistent strengths across DirectX and compute workloads. Its Passmark G3D score of 11466 indicates strong general 3D rendering performance, while its Passmark GPU Compute score of 4913 shows robust compute throughput outside of OpenCL. The Geekbench Vulkan score of 41786 further demonstrates that the P4000 handles modern low-level APIs effectively, which is relevant for professional visualization and CAD workloads that rely on Vulkan support.

The GTX 675MX, by contrast, has a much narrower recorded footprint. Its Geekbench Metal score of 6131 is the only metric where it has a recorded result that the P4000 does not, but the P4000’s lack of a Metal score is a platform artifact, not a performance deficit. In every overlapping test, the GTX 675MX trails significantly. The P4000’s wins in OpenCL, DirectX, and compute workloads suggest it is better suited for tasks that demand parallel processing, such as rendering, simulation, and GPU-accelerated computation. The GTX 675MX, with its older architecture and lower compute throughput, remains viable for basic graphics acceleration but does not compete in the same performance class.

The percentile data reinforces this split. The P4000’s 47th percentile among all GPUs places it in the upper half of the database, while the GTX 675MX’s 43rd percentile places it just below. In practical terms, the P4000 is a mid-range professional card that can handle demanding workloads, while the GTX 675MX is a legacy mobile part that has fallen behind modern integrated and entry-level discrete solutions. The GTX 675MX’s nearest rivals include the AMD Radeon 880M and NVIDIA GeForce MX330, both of which are relatively low-power parts, confirming that the GTX 675MX now competes with entry-level hardware rather than professional or high-end consumer cards.

Architecture Differences

The architectural gap between these two GPUs is substantial. The Quadro P4000 is built on the Pascal architecture, specifically the GP104 chip, while the GTX 675MX uses the Kepler architecture with the GK104 chip. Pascal was designed for higher efficiency and better compute performance, and the manufacturing process reflects this: the P4000 is fabbed on a 16 nm process at TSMC, while the GTX 675MX uses a 28 nm process, also at TSMC. The smaller process node allows the P4000 to pack significantly more transistors: 7,200 million on a 314 mm² die, compared to 3,540 million on a 294 mm² die for the GTX 675MX. This results in a transistor density of 22.9M per mm² for the P4000 versus 12.0M per mm² for the GTX 675MX, a nearly twofold difference in density.

The core configurations diverge accordingly. The P4000 features 1792 shading units, 112 texture mapping units, and 64 ROPs. The GTX 675MX has 960 shading units, 80 TMUs, and 32 ROPs. These differences translate directly into throughput metrics. The P4000 achieves a pixel rate of 94.72 GPixel/s and a texture rate of 165.8 GTexel/s, while the GTX 675MX manages only 13.08 GPixel/s and 52.32 GTexel/s. The FP32 compute output is similarly lopsided: the P4000 delivers 5.304 TFLOPS, while the GTX 675MX delivers 1,255.7 GFLOPS, which is approximately 1.26 TFLOPS. The P4000 also supports FP16 at 82.88 GFLOPS with a 1:64 ratio, a feature absent from the GTX 675MX’s recorded data.

Memory architecture also separates the two. The P4000 comes with 8 GB of GDDR5 on a 256-bit bus, yielding a bandwidth of 243.3 GB/s. The GTX 675MX offers 2 GB of GDDR5 on a 256-bit bus, but its bandwidth is only 115.2 GB/s. The memory clock tells the story: the P4000 runs at 1901 MHz with 7.6 Gbps effective, while the GTX 675MX runs at 900 MHz with 3.6 Gbps effective. The P4000’s memory subsystem delivers more than double the bandwidth, which is critical for large datasets and high-resolution textures in professional applications.

Feature support also differs. The P4000 supports DirectX 12 with feature level 12_1, OpenGL 4.6, and Vulkan 1.4. The GTX 675MX supports DirectX 12 with feature level 11_0, OpenGL 4.6, and Vulkan 1.2.175. The P4000’s higher Vulkan version and stronger DirectX feature level indicate better compatibility with modern graphics APIs. The P4000 also uses a PCIe 3.0 x16 interface, while the GTX 675MX uses an MXM-B (3.0) module interface, reflecting its mobile origins. Display outputs also diverge: the P4000 provides 4x DisplayPort 1.4a, while the GTX 675MX relies on portable device dependent outputs, which is typical for laptop implementations.

Specification Differences

The recorded specifications show clear differences in nearly every category. The P4000 has a base clock of 1202 MHz and a boost clock of 1480 MHz, while the GTX 675MX has no recorded base or boost clocks. The P4000’s memory clock is 1901 MHz (7.6 Gbps effective), compared to the GTX 675MX’s 900 MHz (3.6 Gbps effective). Memory size differs: 8 GB versus 2 GB. The bus widths are the same at 256 bit, but bandwidth differs at 243.3 GB/s versus 115.2 GB/s. Shading units are 1792 versus 960, TMUs are 112 versus 80, and ROPs are 64 versus 32. Pixel rate is 94.72 GPixel/s versus 13.08 GPixel/s, and texture rate is 165.8 GTexel/s versus 52.32 GTexel/s.
