NVIDIA GeForce GTX 465 vs NVIDIA Quadro P5000 Comparison

Head-to-Head Benchmarks

The benchmark database records a single direct head-to-head comparison between the NVIDIA GeForce GTX 465 and the NVIDIA Quadro P5000, and the result is decisive. In the Geekbench OpenCL test, the Quadro P5000 scores 52,509 points against 9,294 points for the GTX 465. That represents a delta of 82.3 percent, meaning the Quadro P5000 outperforms the GTX 465 by an enormous margin in this compute-oriented workload. The GTX 465 is not merely behind; it is off the chart in comparison.

To contextualize the GTX 465's score, the database places it at the 46th percentile among all GPUs. Its nearest rivals in the ranking include the NVIDIA GeForce GTX 850M with an average score of 9,302 (a delta of -0.1 percent), the AMD Radeon R7 M380 at 9,313 (-0.2 percent), the NVIDIA GeForce GTX 960 at 9,273 (+0.2 percent), and the AMD Radeon Vega 8 at 9,221 (+0.8 percent). The GTX 465 sits squarely in a cluster of mid-range mobile and entry-level desktop parts, with all four rivals within roughly one percent of its score. This is a telling sign: the GTX 465, despite its desktop pedigree and 200 W thermal design power, performs at a level comparable to much lower-powered hardware from later generations.

The Quadro P5000, by contrast, sits at the 41st percentile in the overall database, which is slightly lower than the GTX 465's percentile. However, its average benchmark score across all recorded tests is 8,039, dragged down by several low-scoring DirectX and 2D workloads. Its nearest rivals are the NVIDIA GeForce GTX 880M at 8,040 (0.0 percent delta), the NVIDIA GeForce GTX 650 Ti at 8,053 (-0.2 percent), the NVIDIA GeForce GTX 650 Ti Boost at 8,067 (-0.3 percent), and the NVIDIA GRID K2 at 8,080 (-0.5 percent). The average score picture is misleading for the Quadro P5000, because its OpenCL result of 52,509 is by far its strongest recorded output, while its DirectX 9, 10, 11, and 12 scores are much lower: 170, 77, 102, and 44 respectively on Passmark. The GTX 465 has no recorded DirectX or Vulkan results in the database, so the only fair apples-to-apples comparison is the OpenCL test, where the Quadro P5000 wins outright.

The delta of -82.3 percent in the head-to-head is a stark indicator of generational shift. The GTX 465's OpenCL score of 9,294 is less than one-fifth of the Quadro P5000's 52,509. In practical terms, any compute task that relies on OpenCL performance would finish on the Quadro P5000 in a fraction of the time required by the GTX 465. The database shows only one head-to-head benchmark, and the Quadro P5000 claims the sole win.

Architecture Differences

The two cards come from entirely different eras of NVIDIA's engineering. The GeForce GTX 465 is built on the GF100 chip using the Fermi architecture, fabricated on a 40 nm process at TSMC. The Quadro P5000 uses the GP104 chip with the Pascal architecture, also from TSMC but on a 16 nm process. The process node shrink from 40 nm to 16 nm is the single most important architectural distinction, as it enables vastly higher transistor counts and clock speeds while reducing power consumption.

Transistor counts tell the story plainly. The GF100 packs 3,100 million transistors into a die size of 529 mm², yielding a transistor density of 5.9 million transistors per square millimeter. The GP104 integrates 7,200 million transistors into a much smaller die of 314 mm², achieving a density of 22.9 million per square millimeter. That is nearly four times the transistor density, which explains how the Quadro P5000 can offer so many more execution units despite its smaller physical footprint.

The shading unit count is a major differentiator. The GTX 465 has 352 shading units, 44 texture mapping units, and 32 ROPs. The Quadro P5000 has 2,560 shading units, 160 TMUs, and 64 ROPs. The Quadro P5000 has more than seven times the shading units, more than three and a half times the TMUs, and exactly double the ROPs. These numbers translate directly into the pixel and texture rates recorded in the database: the GTX 465 produces 13.38 GPixel/s and 26.75 GTexel/s, while the Quadro P5000 produces 110.9 GPixel/s and 277.3 GTexel/s. The Quadro P5000 is roughly eight times faster in pixel throughput and over ten times faster in texture throughput.

Clock behavior also differs fundamentally. The GTX 465 has no base or boost clock listed in the database; only its memory clock of 802 MHz (3.2 Gbps effective) is recorded. The Quadro P5000 has a base clock of 1607 MHz and a boost clock of 1733 MHz, with a memory clock of 1127 MHz (9 Gbps effective). The Quadro P5000's memory bandwidth of 288.5 GB/s is nearly triple the GTX 465's 102.7 GB/s. Both cards use a 256-bit memory bus, but the GTX 465 uses GDDR5 while the Quadro P5000 uses GDDR5X, which explains the bandwidth gap. Memory capacity is also a chasm: 1024 MB on the GTX 465 versus 16 GB on the Quadro P5000.

The floating-point capabilities are equally lopsided. The GTX 465 delivers 855.4 GFLOPS of FP32 performance. The Quadro P5000 delivers 8.873 TFLOPS, which is 8,873 GFLOPS, more than ten times the GTX 465. The Quadro P5000 also lists FP16 at 138.6 GFLOPS with a 1:64 ratio, while the GTX 465 has no recorded FP16 capability. API support shows the age gap: the GTX 465 supports DirectX 12 (11_0) and OpenGL 4.6, but has no Vulkan listing. The Quadro P5000 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The newer DirectX feature level and Vulkan support on the Quadro P5000 reflect its Pascal-generation architecture.

The Verdict

The data points to an unambiguous conclusion for compute-heavy workloads: the Quadro P5000 is the superior card by a wide margin. Its OpenCL score of 52,509 dwarfs the GTX 465's 9,294, and its FP32 throughput of 8.873 TFLOPS is more than ten times the GTX 465's 855.4 GFLOPS. Anyone running OpenCL-based applications, GPU compute, or modern DirectX 12 (12_1) titles should choose the Quadro P5000 without hesitation. The GTX 465 cannot compete on any recorded metric except power draw, where it actually consumes more: 200 W versus 180 W for the Quadro P5000, despite delivering far less performance.

The GTX 465's only consolation is its percentile ranking: 46th percentile versus 41st for the Quadro P5000. This is because the GTX 465 has a single recorded benchmark score, while the Quadro P5000's average is pulled down by weak DirectX and 2D results. But the percentile figure is an artifact of the averaging method, not a reflection of real-world capability. In the only direct head-to-head test, the Quadro P5000 wins by 82.3 percent. Pick the GTX 465 only if the workload is strictly legacy DirectX 11 or OpenGL 4.6 with no compute demands and no need for modern API features. Even then, the GTX 465's higher power draw and older process node make it the less attractive option.

For professional users, the Quadro P5000's 16 GB of GDDR5X memory and 288.5 GB/s bandwidth are clearly aimed at large datasets and high-resolution textures. The GTX 465's 1024 MB of GDDR5 is a hard ceiling for modern workloads. The Quadro P5000 also offers four DisplayPort 1.4a outputs and one DVI, while the GTX 465 offers two DVI and one mini-HDMI 1.3a. The display output differences matter for multi-monitor professional setups.
