NVIDIA GeForce GTX 465 vs NVIDIA Quadro P4000 Comparison

Where Each One Wins

The benchmark data splits cleanly between these two NVIDIA cards, with the Quadro P4000 taking every recorded head-to-head victory. In the single shared test, Geekbench OpenCL, the P4000 scores 36,212 against the GTX 465’s 9,294 — a 289.6% advantage. That is not a marginal lead; it is a generational gap expressed in raw compute throughput. The P4000 also holds wins across the broader benchmark suite: it posts 11,466 in Passmark G3D, 4,913 in Passmark GPU Compute, and 1,115 in 3DMark Steel Nomad DX12. The GTX 465 has no recorded scores in any of those tests, so the comparison is necessarily lopsided — but the available data leaves no ambiguity about which card dominates.

Where the GTX 465 could theoretically claim ground is in legacy compatibility. It supports DirectX 12 (11_0), while the P4000 supports DirectX 12 (12_1). The GTX 465 lacks Vulkan support entirely, whereas the P4000 lists Vulkan 1.4. For older applications built around DirectX 11 or earlier, the GTX 465’s feature set is sufficient, but it does not outperform the P4000 in any measured metric. The P4000’s percentile ranking of 47 versus the GTX 465’s 46 places both near the middle of the GPU distribution, yet the average benchmark score gap — 9,665 for the P4000 versus 9,294 for the GTX 465 — shows the newer card is consistently ahead.

Architecture Differences

The two cards come from different eras of NVIDIA design. The Quadro P4000 uses the GP104 chip on the Pascal architecture, built on a 16 nm process at TSMC. The GeForce GTX 465 uses the GF100 chip on the Fermi architecture, built on a 40 nm process, also at TSMC. That process shrink is significant: the P4000 packs 7,200 million transistors onto a 314 mm² die, achieving a transistor density of 22.9 million per square millimeter. The GTX 465 has 3,100 million transistors on a much larger 529 mm² die, yielding just 5.9 million per square millimeter. The P4000 is denser by a factor of nearly four, which explains how it delivers far more compute in a smaller physical footprint.

Core counts reinforce the architectural leap. The P4000 has 1,792 shading units, 112 texture mapping units, and 64 ROPs. The GTX 465 has 352 shading units, 44 TMUs, and 32 ROPs. That is a 5.1x advantage in shaders, a 2.5x advantage in TMUs, and a 2x advantage in ROPs. Clock speeds also favor the P4000: it runs at 1202 MHz base and 1480 MHz boost, while the GTX 465 has no recorded base or boost clocks — its memory clock is 802 MHz (3.2 Gbps effective) versus the P4000’s 1901 MHz (7.6 Gbps effective). The memory subsystems differ in capacity (8 GB versus 1024 MB) but share the same 256-bit bus width. Bandwidth tells the story: 243.3 GB/s for the P4000 versus 102.7 GB/s for the GTX 465.

Feature support diverges sharply. The P4000 exposes DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4; the GTX 465 exposes DirectX 12 (11_0) and OpenGL 4.6, with no Vulkan listed. The P4000 offers four DisplayPort 1.4a outputs; the GTX 465 offers two DVI and one mini-HDMI 1.3a. Power requirements also reflect the generational split: the P4000 draws 105 W with a single 6-pin connector and a 300 W suggested PSU, while the GTX 465 draws 200 W with dual 6-pin connectors and a 550 W suggested PSU. The P4000 is single-slot; the GTX 465 is dual-slot.

Head-to-Head Benchmarks

The only direct head-to-head benchmark available is Geekbench OpenCL, and the result is decisive. The Quadro P4000 scores 36,212, while the GTX 465 scores 9,294. That is a delta of 289.6% in favor of the P4000 — nearly four times the raw OpenCL performance. This test exercises general-purpose GPU compute, and the P4000’s Pascal architecture with its 5.304 TFLOPS FP32 throughput simply overwhelms the Fermi card’s 855.4 GFLOPS. The gap is consistent with the underlying hardware: more shaders, higher clocks, and a newer memory subsystem all feed into this result.

Beyond the head-to-head, the P4000’s other benchmark scores provide context for its overall positioning. Its Passmark G3D score of 11,466 and Passmark GPU Compute score of 4,913 reflect strong DirectX and compute performance. The 3DMark Steel Nomad DX12 score of 1,115 shows it handles modern rendering workloads. The GTX 465 has no entries in those tests, so a direct comparison is impossible — but its absence from those benchmarks is itself informative. The Geekbench Vulkan score of 41,786 for the P4000 further demonstrates its API modernity, while the GTX 465 cannot run Vulkan at all.

The P4000’s nearest rivals in the database — the AMD Radeon Pro WX 2100 (delta 0.1%), NVIDIA GeForce GTX 960M (delta 0.2%), and NVIDIA Quadro K5000 (delta 0.3%) — all sit within a fraction of a percent of its average score. This suggests the P4000 is a mid-pack performer among contemporary cards. The GTX 465’s nearest rivals — the GeForce GTX 850M (delta -0.1%), Radeon R7 M380 (delta -0.2%), and GeForce GTX 960 (delta 0.2%) — likewise cluster tightly, but at a lower absolute level. The two cards occupy adjacent percentile ranks (47 versus 46), yet the P4000’s average score is 371 points higher, a margin that grows dramatically when comparing the head-to-head test.

The Verdict

The data points one direction without qualification. The Quadro P4000 wins every recorded benchmark, holds a 289.6% lead in the sole head-to-head test, and offers a newer architecture, more memory, higher bandwidth, and broader API support. The GTX 465 is an end-of-life Fermi product from 2010; the P4000 is an end-of-life Pascal product from 2017. In raw numbers, the P4000 delivers 5.304 TFLOPS of FP32 versus 855.4 GFLOPS, 243.3 GB/s of memory bandwidth versus 102.7 GB/s, and 8 GB of VRAM versus 1024 MB.

For a user choosing between these two cards today, the P4000 is the only sensible pick for any workload involving modern APIs, large datasets, or compute acceleration. Its 4x DisplayPort 1.4a outputs suit multi-monitor professional setups, while its single-slot design and 105 W TDP fit into dense workstations. The GTX 465’s dual-slot footprint, 200 W draw, and dual 6-pin power requirement belong to an older era of high-power consumer graphics.

The GTX 465 could only appeal to someone seeking a period-accurate part for legacy systems or testing, given its DirectX 12 (11_0) support and 2x DVI outputs. But even there, the P4000 matches or exceeds its feature set. The launch MSRP of 815 USD for the P4000 versus 279 USD for the GTX 465 reflects their different market positions — professional versus consumer — but the performance data shows the P4000 justifies its positioning. The verdict is straightforward: the Quadro P4000 wins on every measurable axis, and the GTX 465’s sole advantage is its lower historical launch price, which does not translate into any benchmark victory.
