NVIDIA Quadro P6000 vs NVIDIA RTX A1000 Mobile Comparison

Head-to-Head Benchmarks

The benchmark database records two synthetic workload comparisons between the NVIDIA Quadro P6000 and the NVIDIA RTX A1000 Mobile, and the results are decisive in one direction. In Geekbench OpenCL, the Quadro P6000 scores 66,382 against the RTX A1000 Mobile's 48,703, a 36.3% advantage. The Vulkan test widens that gap further: 73,590 versus 46,782, putting the Quadro P6000 57.3% ahead. Across both recorded tests, the Quadro P6000 claims two wins, while the RTX A1000 Mobile records none.

These deltas are substantial, and they align with the overall average benchmark scores in the database. The Quadro P6000 carries an average benchmark score of 69,986, while the RTX A1000 Mobile sits at 47,743. That translates to a 46.6% difference in aggregate performance, roughly consistent with the OpenCL margin but slightly narrower than the Vulkan margin. The Vulkan result is particularly lopsided, suggesting the older Pascal architecture holds a stronger relative advantage in that specific API workload.

Context from the nearest rivals helps frame these numbers. The Quadro P6000's average score places it between the AMD Radeon Pro WX 8200 (69,870, just 0.2% behind) and the NVIDIA RTX A3000 Mobile (70,140, 0.2% ahead). It also sits 1.2% behind the AMD Radeon RX 6600 LE (70,829) and 1.4% ahead of the NVIDIA CMP 90HX (69,000). The RTX A1000 Mobile, by contrast, is 1.5% behind the AMD Radeon RX 6800 XT (48,477) and 2.2% ahead of the AMD Radeon RX 6550M (46,702). It also leads the Intel Arc A530M (46,614) by 2.4% and the AMD Radeon RX 5600M (46,601) by 2.5%.

In other words, the Quadro P6000 competes in a higher performance tier altogether. Its nearest rivals are workstation and high-end desktop parts, while the RTX A1000 Mobile's rivals are mostly mid-range mobile and entry-level desktop GPUs. The head-to-head data confirms that the Quadro P6000 is not merely faster; it operates in a different performance class, with margins that range from roughly a third to more than half depending on the workload.

Where Each One Wins

The recorded data gives the Quadro P6000 a clean sweep, but the nature of the wins matters for real-world use. In OpenCL, a workload that often reflects general compute and rendering tasks, the 36.3% lead indicates the Quadro P6000 handles parallel compute with significantly more headroom. The 24 GB GDDR5X memory and 432.8 GB/s bandwidth are clearly factors here, as large datasets and high-resolution textures place heavy demands on memory capacity and throughput.

The Vulkan result, where the Quadro P6000 leads by 57.3%, points to an even stronger advantage in graphics-heavy API workloads. Vulkan is commonly used in professional visualization and modern game engines, so this margin suggests the Quadro P6000 is the better choice for GPU-accelerated rendering pipelines that leverage explicit control over the hardware. The RTX A1000 Mobile's 4 GB GDDR6 memory and 176.0 GB/s bandwidth are modest by comparison, which likely explains the steep drop in Vulkan performance.

For the RTX A1000 Mobile, the wins are not in raw performance but in efficiency and form factor. It carries a 60 W TDP against the Quadro P6000's 250 W, making it suitable for thin-and-light mobile workstations where power budgets are tight. The RTX A1000 Mobile is also an IGP (integrated graphics package) with no power connectors, whereas the Quadro P6000 is a dual-slot card requiring a 1x 8-pin connector and a 600 W suggested PSU. These are not benchmark wins, but they define where the RTX A1000 Mobile fits: mobile content creation, lightweight CAD, and portable workstations where the Quadro P6000's physical footprint and power draw are prohibitive.

The Quadro P6000, meanwhile, is a desktop card with a 267 mm length and dual-slot design, clearly aimed at stationary workstations. Its 24 GB memory capacity dwarfs the RTX A1000 Mobile's 4 GB, so the Quadro P6000 is the obvious pick for tasks like large-scale 3D rendering, scientific visualization, and machine learning inference where memory capacity is a hard constraint. The benchmark data supports this: the Quadro P6000's wins are decisive, and its memory advantages are reflected in the scores.

Architecture Differences

The two GPUs come from different design generations and foundries. The Quadro P6000 uses the GP102 chip on the Pascal architecture, manufactured on a 16 nm process at TSMC. The RTX A1000 Mobile uses the GA107 chip on the Ampere architecture, fabricated on an 8 nm process at Samsung. The process node difference is significant: 16 nm versus 8 nm, which contributes to the RTX A1000 Mobile's smaller die and lower power draw.

Transistor counts and die sizes tell the story of two very different designs. The Quadro P6000 packs 11,800 million transistors on a 471 mm² die, yielding a transistor density of 25.1 million per mm². The RTX A1000 Mobile has 8,700 million transistors on a 200 mm² die, which works out to 43.5 million per mm². The Ampere chip is far denser, reflecting the more advanced 8 nm process, but it is also much smaller overall.

The memory subsystems are entirely different in both capacity and type. The Quadro P6000 uses 24 GB of GDDR5X on a 384 bit bus, delivering 432.8 GB/s of bandwidth. The RTX A1000 Mobile uses 4 GB of GDDR6 on a 128 bit bus, with 176.0 GB/s of bandwidth. The Quadro P6000's memory clock is listed as 1127 MHz (9 Gbps effective), while the RTX A1000 Mobile runs at 1375 MHz (11 Gbps effective). The faster per-pin speed on the Ampere part cannot compensate for the much narrower bus and smaller capacity.

Compute resources also diverge sharply. The Quadro P6000 has 3,840 shading units, 240 texture mapping units, and 96 raster output units. The RTX A1000 Mobile has 2,048 shading units, 64 TMUs, and 32 ROPs. The Quadro P6000 leads in every count, which drives its higher pixel rate (157.9 GPixel/s versus 36.48 GPixel/s) and texture rate (394.8 GTexel/s versus 72.96 GTexel/s).

The Ampere architecture brings features the Pascal part lacks. The RTX A1000 Mobile includes 16 ray tracing cores and 64 tensor cores, while the Quadro P6000 has neither. This affects API support: the RTX A1000 Mobile supports DirectX 12 Ultimate (12_2), while the Quadro P6000 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so those APIs are not differentiators.

Floating-point performance shows a generational split. The Quadro P6000 delivers 12.63 TFLOPS for FP32, while the RTX A1000 Mobile manages 4.669 TFLOPS. For FP16, the Quadro P6000 is severely limited at 197.4 GFLOPS with a 1:64 ratio, meaning it processes FP16 at a tiny fraction of its FP32 rate. The RTX A1000 Mobile, by contrast, achieves 4.669 TFLOPS for FP16 at a 1:1 ratio, matching its FP32 throughput. This makes the Ampere part far more capable for FP16 workloads like AI inference, despite its lower overall compute.

The bus interface also differs: the Quadro P6000 uses PCIe 3.0 x16, while the RTX A1000 Mobile uses PCIe 4.0 x8. The newer standard on the mobile part offers higher per-lane bandwidth, but the Quadro P6000's full x16 connection provides more total lanes.

Specification Differences

The two cards differ on nearly every measurable specification. The Quadro P6000 has a 16 nm process node; the RTX A1000 Mobile uses 8 nm. The Quadro P6000's chip is GP102 on Pascal, while the RTX A1000 Mobile uses GA107 on Ampere. Transistor counts are 11,800 million versus 8,700 million, and die sizes are 471 mm² versus 200 mm². Transistor density is 25.1M per mm² versus 43.5M per mm².

Clock speeds: the Quadro P6000 has a base of 1506 MHz and boost of 1645 MHz; the RTX A1000 Mobile has a base of 630 MHz and boost of 1140 MHz.

Memory capacity is 24 GB versus 4 GB, type is GDDR5X versus GDDR6, bus width is 384 bit versus 128 bit, and bandwidth is 432.8 GB/s versus 176.0 GB/s.

Shader resources: 3,840 versus 2,048 shading units, 240 versus 64 TMUs, 96 versus 32 ROPs. The RTX A1000 Mobile has 16 RT cores and 64 tensor cores; the Quadro P6000 has none. Pixel rate is 157.9 GPixel/s versus 36.48 GPixel/s, texture rate is 394.8 GTexel/s versus 72.96 GTexel/s.
