NVIDIA GeForce GTX 750 vs NVIDIA Quadro P5000 Comparison

The Verdict

The recorded benchmark data presents an unusual split decision. In the two shared head-to-head tests, each card claims one victory. The NVIDIA Quadro P5000 dominates Geekbench OpenCL with a score of 52,509, which is 463.7% higher than the GeForce GTX 750's 9,315. However, in Geekbench Vulkan, the older GTX 750 turns the tables, scoring 8,078 against the Quadro's 6,342, a 21.5% advantage. The database shows a tied 1-1 win count in direct comparisons.

The average benchmark scores suggest the Quadro P5000 sits higher overall at 8,039, while the GTX 750 averages 7,222. Both cards occupy similar percentile positions among all GPUs: the Quadro at 41 and the GTX 750 at 40. The GTX 750's nearest rivals include the AMD Radeon Vega 8 Mobile (0.3% ahead), NVIDIA GeForce GTX 560 SE (0.7% ahead), Intel Iris Pro Graphics P580 (0.7% ahead), and NVIDIA GeForce GTX 970 (0.9% ahead). The Quadro P5000's nearest rivals are clustered extremely close: the GTX 880M (0% delta), GTX 650 Ti (-0.2%), GTX 650 Ti Boost (-0.3%), and GRID K2 (-0.5%). This indicates the Quadro P5000's average score is essentially tied with several older gaming GPUs, while the GTX 750 sits in a comparable percentile band despite a lower absolute average.

Who should pick which depends entirely on the workload. Users targeting OpenCL compute tasks should choose the Quadro P5000, as its compute output is in a different class. Users focused on Vulkan API performance in legacy or lightweight titles should consider the GTX 750, which demonstrates a measurable advantage in that specific API test. The Quadro P5000's additional features, including 16 GB of GDDR5X memory and a 288.5 GB/s bandwidth, make it the appropriate choice for large dataset workloads. The GTX 750, with its 55 W power draw and no power connectors, suits constrained builds where power delivery is minimal.

Architecture Differences

The two cards represent distinct NVIDIA architectures from different process nodes. The Quadro P5000 uses the GP104 chip built on the Pascal architecture, manufactured on a 16 nm process at TSMC. It integrates 7,200 million transistors on a 314 mm² die, yielding a transistor density of 22.9 million transistors per square millimeter. The GTX 750 uses the GM107 chip based on the Maxwell architecture, also fabricated by TSMC but on a 28 nm process. It contains 1,870 million transistors on a 148 mm² die, with a density of 12.6 million transistors per square millimeter.

The compute resources differ dramatically. The Quadro P5000 packs 2,560 shading units, 160 texture mapping units, and 64 ROPs. The GTX 750 has 512 shading units, 32 TMUs, and 16 ROPs. This 5x difference in shading units and 4x difference in TMUs and ROPs explains the Quadro's overwhelming OpenCL lead. Clock speeds also favor the Quadro: base clock of 1,607 MHz versus 1,020 MHz, and boost clock of 1,733 MHz versus 1,085 MHz.

Memory architecture diverges substantially. The Quadro P5000 uses 16 GB of GDDR5X on a 256-bit bus, delivering 288.5 GB/s of bandwidth. The GTX 750 uses 1,024 MB of GDDR5 on a 128-bit bus, providing 80.19 GB/s. The Quadro's memory clock runs at 1,127 MHz with 9 Gbps effective transfer, while the GTX 750 operates at 1,253 MHz with 5 Gbps effective. Despite the lower memory clock, the Quadro's wider bus and newer memory type produce nearly 3.6 times the bandwidth.

The API support shows a key difference in DirectX. The Quadro P5000 supports DirectX 12 (12_1), while the GTX 750 is limited to DirectX 12 (11_0). Both support OpenGL 4.6 and Vulkan 1.4. The GTX 750 also records a Geekbench Metal score of 4,274, a test absent from the Quadro P5000's data.

Where Each One Wins

The head-to-head data reveals a clear workload split. In OpenCL compute, the Quadro P5000 wins decisively with 52,509 points versus 9,315, a 463.7% margin. This reflects the massive difference in shading units and memory bandwidth. The Quadro's 8.873 TFLOPS FP32 throughput, 277.3 GTexel/s texture rate, and 110.9 GPixel/s pixel rate position it for heavy parallel computation, 3D rendering, and scientific workloads.

In Vulkan graphics, the GTX 750 wins with 8,078 points versus 6,342, a 21.5% advantage. This result is counterintuitive given the Quadro's superior hardware specifications. The data suggests the GTX 750's Maxwell architecture, despite being older, delivers more efficient Vulkan driver performance or the benchmark favors lower-overhead execution. The GTX 750's smaller footprint (145 mm length, single-slot) and 55 W TDP also make it suitable for small form factor systems.

The Quadro P5000's additional benchmarks show strengths across multiple DirectX versions: PassMark DirectX 9 at 170, DirectX 10 at 77, DirectX 11 at 102, and DirectX 12 at 44. Its PassMark G3D score reaches 12,634, with a GPU compute score of 6,508 and G2D score of 674. The GTX 750 lacks these PassMark results in the database, so no direct comparison exists for those tests.

The production status of both cards is end-of-life. The Quadro P5000 was released on 2016-09-30, while the GTX 750 launched on 2014-02-17. The Quadro's predecessor is Quadro Maxwell with successor Quadro Volta, whereas the GTX 750's predecessor is GeForce 600 and successor is GeForce 900.

Head-to-Head Benchmarks

The database contains exactly two shared benchmark results, and they tell opposite stories. The Geekbench OpenCL test delivers the most lopsided result in the entire comparison. The Quadro P5000 records 52,509 points, dwarfing the GTX 750's 9,315. The delta of 463.7% means the Quadro produces more than five times the OpenCL throughput. This aligns with its architectural resources: 2,560 shading units versus 512, 64 ROPs versus 16, and 288.5 GB/s memory bandwidth versus 80.19 GB/s. The 16 nm Pascal process with 7,200 million transistors provides a substantial compute foundation that the 28 nm Maxwell chip with 1,870 million transistors cannot match.

The Geekbench Vulkan result reverses expectations. The GTX 750 scores 8,078, beating the Quadro P5000's 6,342 by 21.5%. This is a surprising outcome because the Quadro's raw specifications are superior in every measurable category except memory clock (1,127 MHz versus 1,253 MHz). The Vulkan test may favor lower latency and simpler hardware scheduling, or the GTX 750's older driver stack may execute this particular workload more efficiently. The data does not explain the cause, only the outcome.

Looking at the Quadro P5000's broader benchmark suite, its PassMark results show a mixed profile across DirectX versions. DirectX 9 scores highest at 170, followed by DirectX 11 at 102, DirectX 10 at 77, and DirectX 12 at 44. The G3D score of 12,634 and GPU compute score of 6,508 indicate solid general-purpose performance. The 3DMark Steel Nomad DX12 test records 1,330 points. The GTX 750 has no corresponding entries in these tests, so cross-card comparisons for those workloads are not available in the database.

The nearest rival data places both cards in similar competitive territory. The Quadro P5000's closest rival, the GTX 880M, matches its 8,040 average score with a 0% delta. The GTX 650 Ti trails by only 0.2%, the GTX 650 Ti Boost by 0.3%, and the GRID K2 by 0.5%. This clustering suggests the Quadro P5000's average score does not reflect its OpenCL dominance, as the average includes all recorded tests. The GTX 750's nearest rivals show it slightly behind the AMD Radeon Vega 8 Mobile (0.3% gap), GTX 560 SE (0.7%), Intel Iris Pro Graphics P580 (0.7%), and GTX 970 (0.9%). Both cards occupy the 40th to 41st percentile range, meaning they outperform roughly 60% of all GPUs in the database.

Specification Differences

The two cards differ across nearly every specification field. The process node shows a two-generation gap: 16 nm for the Quadro P5000 versus 28 nm for the GTX 750.

The shading units, TMUs, and ROPs all favor the Quadro P5000 by multiples of 4 to 5: 2,560 versus 512 shading units, 160 versus 32 TMUs, and 64 versus 16 ROPs. The pixel rate is 110.9 GPixel/s versus 17.36 GPixel/s, and texture rate is 277.3 GTexel/s versus 34.72 GTexel/s. FP32 throughput is 8.873 TFLOPS versus 1,111.0 GFLOPS. The Quadro P5000 lists FP16 at 138.6 GFLOPS (1:64 ratio), while the GTX 750 has no FP16 data.

Power requirements diverge sharply. The Quadro P5000 draws 180 W TDP, requires a dual-slot cooler, and uses a single 8-pin power connector with a suggested 450 W PSU. The GTX 750 draws only 55 W, fits in a single slot, needs no power connectors, and suggests a 250 W PSU. Physical dimensions also differ: the Quadro measures 267 mm (10.5 inches) in length and 111 mm (4.4 inches) in height, while the GTX 750 is 145 mm (5.7 inches) long with no recorded height.

Memory specifications show the Quadro P5000 with 16 GB GDDR5X on a 256-bit bus, while the GTX 750 has 1,024 MB GDDR5 on a 128-bit bus. Bandwidth is 288.5 GB/s versus 80.19 GB/s. Memory clocks are 1,127 MHz (9 Gbps effective) versus 1,253 MHz (5 Gbps effective).
