NVIDIA Quadro P6000 vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The benchmark results present a decisive picture. In the Geekbench OpenCL test, the NVIDIA RTX 4500 Ada Generation scores 160,786, while the NVIDIA Quadro P6000 manages 66,382. That is a 142.2% advantage for the Ada-generation card, more than doubling the older Pascal card's output. The gap is nearly as stark in the Geekbench Vulkan test, where the RTX 4500 Ada Generation posts 171,401 versus 73,590 for the Quadro P6000, a 132.9% lead.

These are not marginal improvements. The delta percentages are among the largest seen in the database for comparable workstation cards. The RTX 4500 Ada Generation wins both head-to-head tests, giving it a clean 2-0 record. The Quadro P6000 fails to take a single benchmark in this comparison, and the margin is consistent across both OpenCL and Vulkan workloads, suggesting the advantage is architectural rather than workload-specific.

Looking at the broader database context, the RTX 4500 Ada Generation sits at the 97th percentile of all GPUs, with an average benchmark score of 166,094. Its nearest rivals include the NVIDIA RTX A5500, which scores 165,217 (a 0.5% deficit), and the AMD Radeon PRO W7800 at 164,894 (0.7% behind). The AMD Radeon Pro W6900X edges it out by 1.5% with a score of 168,574, while the NVIDIA A100 PCIe 40 GB trails by 2.2% at 162,504. The RTX 4500 Ada Generation is therefore clustered tightly with the top of the workstation stack, within a few percentage points of several flagship-class accelerators.

The Quadro P6000, by contrast, sits at the 90th percentile with an average score of 69,986. Its nearest rivals are far less impressive: the AMD Radeon Pro WX 8200 scores 69,870 (0.2% behind), the NVIDIA RTX A3000 Mobile scores 70,140 (0.2% ahead), and the AMD Radeon RX 6600 LE scores 70,829 (1.2% ahead). The NVIDIA CMP 90HX trails by 1.4% at 69,000. The Quadro P6000 is competitive with these mid-range and mobile parts, but it is not in the same league as the RTX 4500 Ada Generation.

Where Each One Wins

The RTX 4500 Ada Generation wins across the board in raw compute performance. Its FP32 throughput is listed at 39.63 TFLOPS, compared to 12.63 TFLOPS for the Quadro P6000. That is more than triple the raw floating-point capability. The texture rate tells a similar story: 619.2 GTexel/s versus 394.8 GTexel/s, a 56.8% advantage. Pixel rate also favors the newer card, 206.4 GPixel/s versus 157.9 GPixel/s, a 30.7% lead.

For memory bandwidth, the two cards are nearly identical in raw throughput. The RTX 4500 Ada Generation delivers 432.0 GB/s over a 192-bit bus using GDDR6 memory, while the Quadro P6000 delivers 432.8 GB/s over a 384-bit bus using GDDR5X. The bandwidth difference is negligible, 0.2%, but the newer card achieves it with a narrower bus, indicating much higher per-pin efficiency. Both cards have 24 GB of memory, so capacity is not a differentiator.

Where the Quadro P6000 retains any qualitative edge is in legacy compatibility. It supports 1x DVI alongside its DisplayPort outputs, which the RTX 4500 Ada Generation omits entirely, offering only 4x DisplayPort 1.4a. The Quadro P6000 also has a larger die at 471 mm², though this is a product of its older 16 nm process, not an advantage. Its 96 ROPs exceed the 80 ROPs on the RTX 4500 Ada Generation, but the newer card's higher clock speeds and shader count more than compensate.

The RTX 4500 Ada Generation is the clear winner for any modern workload that leverages Vulkan, OpenCL, or DirectX 12 Ultimate features. The Quadro P6000 supports DirectX 12 (12_1), but the RTX 4500 Ada Generation supports DirectX 12 Ultimate (12_2), which includes additional features like ray tracing and mesh shaders. The Pascal card has no dedicated ray tracing cores and no tensor cores, while the Ada card includes 60 RT cores and 240 tensor cores, enabling hardware-accelerated ray tracing and AI workloads.

Architecture Differences

The architectural gap between these two cards is generational. The RTX 4500 Ada Generation is built on the Ada Lovelace architecture using the AD103 chip, fabricated on a 5 nm process at TSMC. The Quadro P6000 uses the Pascal architecture with the GP102 chip, fabricated on a 16 nm process, also at TSMC. The process node difference is substantial: 5 nm versus 16 nm, which explains much of the efficiency and performance gap.

Transistor counts illustrate the scale of the difference. The AD103 chip packs 45,900 million transistors, while the GP102 has 11,800 million. The die sizes are 379 mm² for AD103 and 471 mm² for GP102, meaning the newer chip fits nearly four times as many transistors into a smaller area. Transistor density is 121.1 million per mm² for the Ada card versus 25.1 million per mm² for the Pascal card, a 4.8x density improvement.

The RTX 4500 Ada Generation has 7,680 shading units, 240 TMUs, and 80 ROPs. The Quadro P6000 has 3,840 shading units, 240 TMUs, and 96 ROPs. The shading unit count is exactly double, and the TMU count is identical, but the Ada card's higher clock speeds (2070 MHz base, 2580 MHz boost versus 1506 MHz base, 1645 MHz boost) push its fill rates far ahead. The RT core and tensor core counts on the Ada card, 60 and 240 respectively, have no equivalent on the Pascal card, which lists null for both.

Memory technology differs as well. The RTX 4500 Ada Generation uses GDDR6 at 18 Gbps effective, while the Quadro P6000 uses GDDR5X at 9 Gbps effective. The bus widths are 192-bit and 384-bit, respectively, but as noted, bandwidth ends up nearly identical. The Ada card achieves this with half the bus width, indicating better memory compression and controller efficiency. The PCIe interface also advances from 3.0 x16 on the Pascal card to 4.0 x16 on the Ada card, doubling the theoretical host link bandwidth.

Power efficiency is a notable divergence. The RTX 4500 Ada Generation has a 210 W TDP, while the Quadro P6000 has a 250 W TDP. Despite consuming 16% less power, the Ada card delivers roughly 3.1x the FP32 throughput. The suggested PSU requirement is also lower for the Ada card, 550 W versus 600 W. The RTX 4500 Ada Generation requires no external power connectors, drawing all power from the PCIe slot, while the Quadro P6000 requires a single 8-pin connector. The Ada card is also shorter at 245 mm versus 267 mm for the Pascal card.

The Verdict

The data is unambiguous. The NVIDIA RTX 4500 Ada Generation outperforms the NVIDIA Quadro P6000 by 142.2% in OpenCL and 132.9% in Vulkan. It is faster in every measured metric: FP32 compute, texture rate, pixel rate, and shading unit count. It consumes less power, requires no external power connector, and fits in a shorter chassis. It also supports modern APIs including DirectX 12 Ultimate and Vulkan 1.4, with hardware ray tracing and tensor cores that the Pascal card lacks.

The Quadro P6000 was a capable workstation card in its era, and the database shows it still sits at the 90th percentile of all GPUs. But its nearest rivals are mid-range parts like the RTX A3000 Mobile and the Radeon RX 6600 LE, not the top-tier accelerators that surround the RTX 4500 Ada Generation. The Quadro P6000 retains one legacy advantage: a DVI output for older displays. It also has a wider 384-bit memory bus and more ROPs, but these do not translate into benchmark wins.

For any user choosing between these two cards today, the RTX 4500 Ada Generation is the only rational pick for compute, rendering, or AI workloads. The Quadro P6000 may still be found in existing systems, and its 24 GB of memory remains useful for large datasets, but its performance ceiling is roughly one-third of the newer card. The RTX 4500 Ada Generation is an active product, while the Quadro P6000 is end-of-life. The successor to the Ada card is already listed as Blackwell PRO W, but the current generation remains the benchmark leader in its class.

The verdict is simple: the RTX 4500 Ada Generation wins on every benchmark, every architectural feature, and every efficiency metric. The Quadro P6000 is a legacy product that cannot keep pace.
