NVIDIA GeForce GTX 650 Ti vs NVIDIA Quadro P4000 Comparison

Where Each One Wins

The benchmark data tells a very one-sided story. The NVIDIA Quadro P4000 wins both recorded head-to-head tests, with no wins for the GeForce GTX 650 Ti. This is not a close contest; the P4000 dominates in every measurable category. The two tests that both cards share are Geekbench OpenCL and Geekbench Vulkan, and the Quadro P4000 leads by margins of 359.7% and 407.8%, respectively.

Looking at the broader database, the Quadro P4000 also has a much richer benchmark footprint. It has ten recorded scores spanning DirectX 9, 10, 11, and 12, plus 3DMark Steel Nomad, PassMark G2D, G3D, and GPU compute. The GTX 650 Ti only has two recorded scores, both in Geekbench. This means the P4000 can be evaluated across a wider range of workloads, while the GTX 650 Ti's data profile is far more limited.

The use-case split is therefore clear. The Quadro P4000 is the card for anyone needing serious compute throughput, modern API support, and large memory resources. The GTX 650 Ti, by contrast, belongs to a much older generation and its remaining utility is confined to legacy or low-intensity tasks. The data shows no scenario where the GTX 650 Ti is the better pick based on recorded benchmarks.

Head-to-Head Benchmarks

The Geekbench OpenCL test shows a decisive victory for the Quadro P4000. The P4000 records 36212 points, while the GTX 650 Ti manages only 7877. That is a 359.7% lead, meaning the P4000 delivers roughly four and a half times the OpenCL performance of the older card. This gap is far beyond anything that could be attributed to driver tuning or test variance; it reflects a fundamental difference in compute capability.

The Geekbench Vulkan test is even more lopsided. The P4000 scores 41786, against 8229 for the GTX 650 Ti. The delta here is 407.8%, or about five times the performance. Vulkan is a modern low-level API, and the P4000's Pascal architecture is far better suited to it than the GTX 650 Ti's Kepler design. The GTX 650 Ti supports Vulkan 1.2.175, so it can run the test, but its raw throughput is simply not competitive.

The P4000's additional benchmark results reinforce this picture. Its PassMark G3D score is 11466, its GPU compute score is 4913, and its 3DMark Steel Nomad DX12 score is 1115. The GTX 650 Ti has no comparable scores in the database, so a direct comparison is impossible for those tests. However, the existing data is unambiguous: the P4000 wins every shared workload by a massive margin.

Specification Differences

The two cards differ in almost every specification category. The Quadro P4000 has 8 GB of GDDR5 memory on a 256-bit bus, yielding 243.3 GB/s of bandwidth. The GTX 650 Ti has 1024 MB of GDDR5 on a 128-bit bus, with 86.40 GB/s. That is an eightfold difference in capacity and nearly three times the bandwidth.

The P4000 also has more processing resources. It contains 1792 shading units, 112 texture mapping units, and 64 ROPs. The GTX 650 Ti has 768 shading units, 64 TMUs, and only 16 ROPs. The P4000's pixel rate is 94.72 GPixel/s versus 14.85 GPixel/s for the GTX 650 Ti, and its texture rate is 165.8 GTexel/s versus 59.39 GTexel/s.

Clock speeds differ as well. The P4000 has a base clock of 1202 MHz and a boost clock of 1480 MHz. The GTX 650 Ti has no recorded base or boost clock in the database; only its memory clock is listed, at 1350 MHz (5.4 Gbps effective). The P4000's memory runs at 1901 MHz (7.6 Gbps effective).

Floating-point performance is another major gap. The P4000 delivers 5.304 TFLOPS of FP32, while the GTX 650 Ti delivers 1,425.4 GFLOPS. The P4000 also has a recorded FP16 rate of 82.88 GFLOPS (1:64), whereas the GTX 650 Ti has no FP16 figure listed.

Power and physical specifications are comparable in some ways. Both cards use a single-slot design with a single 6-pin power connector, and both suggest a 300 W power supply. The P4000 is rated at 105 W TDP, while the GTX 650 Ti is rated at 110 W. The P4000 is physically longer at 241 mm (9.5 inches) versus 145 mm (5.7 inches) for the GTX 650 Ti. Display outputs also differ: the P4000 has 4x DisplayPort 1.4a, while the GTX 650 Ti has 2x DVI and 1x mini-HDMI 1.4a.

Architecture Differences

The architectural gap is the root cause of the performance disparity. The Quadro P4000 is built on the Pascal architecture, using the GP104 chip, fabricated on a 16 nm process at TSMC. It packs 7,200 million transistors into a 314 mm² die, giving a transistor density of 22.9 million per square millimeter. The GTX 650 Ti uses the Kepler architecture with the GK106S chip, built on a 28 nm process, also at TSMC. It has 2,540 million transistors on a 221 mm² die, for a density of 11.5 million per square millimeter.

The process node difference is significant: 16 nm versus 28 nm. That allows the P4000 to fit nearly three times as many transistors into a die that is only about 42% larger in area. The density advantage is roughly double, which translates into far more compute units and memory bandwidth per unit of silicon.

The Pascal architecture also brings API support that the older Kepler design cannot match. The P4000 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The GTX 650 Ti supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The DirectX feature level difference, 12_1 versus 11_0, means the P4000 can handle more advanced rendering features in modern games and applications.

The generational context matters too. The P4000 belongs to the Quadro Pascal (Px000) generation, succeeding Quadro Maxwell and preceding Quadro Volta. The GTX 650 Ti is part of the GeForce 600 series, succeeding GeForce 500 and preceding GeForce 700. The P4000 was released in 2017, while the GTX 650 Ti was released in 2012, a five-year gap that explains the architectural chasm.

The Verdict

The data supports only one conclusion: the NVIDIA Quadro P4000 is the superior card in every recorded benchmark. It wins both head-to-head tests, has a higher average score (9665 versus 8053), and ranks higher among all GPUs (47th percentile versus 42nd). The margin of victory is enormous, with leads of 359.7% in OpenCL and 407.8% in Vulkan.

For anyone considering these two cards, the choice depends entirely on context. The P4000 is a professional workstation card with 8 GB of memory, 5.304 TFLOPS of FP32 compute, and modern API support. It is suited for tasks like CAD, scientific visualization, and compute workloads that benefit from large memory and high throughput. Its launch MSRP was 815 USD.

The GTX 650 Ti, with its 1024 MB memory, 1,425.4 GFLOPS of FP32, and older Kepler architecture, is a relic of a past era. Its only advantage is physical size: at 145 mm, it is substantially shorter than the P4000's 241 mm, which could matter in very compact cases. But that is a niche consideration, and the benchmark data shows no performance scenario where the GTX 650 Ti comes out ahead.

The verdict is straightforward: the Quadro P4000 is the card to choose for any workload where performance matters. The GTX 650 Ti should only be considered if the requirement is for a small, low-power card for basic display output, and even then, its dated architecture and limited memory make it a poor fit for modern applications. The database records leave no room for ambiguity.
