NVIDIA RTX A2000 12 GB vs NVIDIA RTX A6000 Comparison

Head-to-Head Benchmarks

The benchmark database records only one direct head-to-head comparison between these two workstation cards, and it is a decisive one. In Geekbench OpenCL, the NVIDIA RTX A6000 scores 193,937 points against 66,998 points for the NVIDIA RTX A2000 12 GB. That is a 189.5% advantage for the larger card, meaning the A6000 delivers nearly three times the raw compute throughput in this cross-platform GPU compute test. The A2000 12 GB has no recorded wins in the direct comparison, so every measurable advantage in this pairing belongs to the A6000.

Looking at the broader average benchmark scores in the database, the A6000 posts an average of 44,075 points across all recorded tests, while the A2000 12 GB averages 34,154 points. That gap translates to roughly a 29% overall performance advantage for the A6000 when considering the full spectrum of workloads captured in the database. The A6000 also sits in the 84th percentile of all GPUs tracked by the database, whereas the A2000 12 GB sits in the 79th percentile, confirming that both cards are above average performers but the A6000 occupies a higher tier.

The A6000's closest rivals in the database include the NVIDIA GeForce RTX 4090 Mobile at 0.9% ahead, the NVIDIA GeForce RTX 4070 Ti at 1.6% behind, the NVIDIA Quadro M6000 at 1.8% ahead, and the NVIDIA GeForce RTX 5050 Mobile at 1.9% ahead. This places the A6000 in the same performance neighborhood as high-end consumer and mobile flagships, which is remarkable for a workstation-oriented product. The A2000 12 GB, by contrast, sits alongside the AMD Radeon RX 560 XT (0.1% ahead), the NVIDIA RTX A1000 (0.2% behind), the AMD Radeon RX 480 (0.5% ahead), and the NVIDIA TITAN V (0.6% behind). The A2000 12 GB is therefore clustered with mid-range and older enthusiast cards, not with the top tier.

The individual benchmark results reinforce this hierarchy. The A6000 records a Passmark G3D score of 22,577, a Passmark GPU Compute score of 14,110, and Geekbench Vulkan score of 164,462. It also posts strong legacy DirectX results: 245 in Passmark DirectX 9, 191 in DirectX 11, 155 in DirectX 10, and 87 in DirectX 12. The A2000 12 GB, unfortunately, only has two recorded benchmarks in the database: the Geekbench OpenCL score of 66,998 and a 3DMark Steel Nomad DX12 score of 1,309. The direct comparison is therefore limited, but the data that does exist points overwhelmingly in one direction.

The Verdict

The data presents a straightforward conclusion for most users: the NVIDIA RTX A6000 is the superior performer in every measurable benchmark category where both cards have data recorded. Its 189.5% lead in Geekbench OpenCL is not a marginal or workload-specific edge, it is a multiplicative gap that spans the entire compute capability of the two cards. The A6000's average score of 84th percentile of all GPUs, combined with an average benchmark score of 44,075 points, places it in a completely different performance class. Users whose work depends on peak GPU compute, large memory throughput, or maximum frame rates should choose the A6000, the data supports no other choice.

The A2000 12 GB, however, has its own recorded strengths, but they are not found in raw performance numbers. The A2000 12 GB carries the same generation and architecture family as the A6000, but operates with a 70 W TDP, no external power connectors, and a suggested PSU rating of 250 W. These are characteristics that make it far easier to deploy in space-constrained or power-limited systems, but the database's percentile ranking of 79th percentile and average score of 34,154 points show that the A2000 12 GB is still a capable workstation option within its own tier. The A2000 12 GB is the card to choose when the workload fits within its 12 GB memory capacity, when the task does not require the A6000's compute lead, and when system integration simplicity matters more than raw benchmark scores.

For users who need to decide between the two based strictly on recorded data, the verdict is clear: the A6000 wins every performance test where both have measurements exist, and its overall database ranking confirms that it belongs among the top 16% of all GPUs tracked. The A2000 12 GB belongs among the top 21%, which is respectable but not comparable.

Architecture Differences

Both cards share the same Ampere architecture and are built on the same 8 nm process at Samsung, but they use different chips. The A6000 is based on the GA102 die, which contains 28,300 million transistors across a 628 mm² die size, resulting in a transistor density of 45.1 million transistors per square millimeter. The A2000 12 GB is based on the smaller GA106 die, which contains 12,000 million transistors across a 276 mm² die size, yielding a transistor density of 43.5 million transistors per square millimeter. The A6000's die is more than twice the physical size and holds more than twice the transistor count, which directly explains its performance advantage.

The shading resources differ dramatically. The A6000 has 10,752 shading units, 336 texture mapping units, and 112 raster operation units. The A2000 12 GB has 3,328 shading units, 104 texture mapping units, and 48 raster operation units. That is roughly 3.2 times more shading units and exactly 3.2 times more TMUs on the A6000, while the ROP count is more than double. The ray tracing and tensor core counts follow the same pattern: the A6000 has 84 RT cores and 336 tensor cores, while the A2000 12 GB has 26 RT cores and 104 tensor cores.

The A6000's compute output is correspondingly higher. It delivers 38.71 TFLOPS of FP32 and the same 38.71 TFLOPS of FP16 (1:1 ratio), while the A2000 12 GB delivers 7.987 TFLOPS in both FP32 and FP16 (1:1 ratio). The A6000's pixel rate is 201.6 GPixel/s and texture rate is 604.8 GTexel/s, versus 57.60 GPixel/s and 124.8 GTexel/s for the A2000 12 GB. These figures show that the A6000 is not just a larger chip, it is a fundamentally more capable compute engine at every level of the graphics pipeline.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so software feature parity is maintained. Both are also listed as end-of-life production status, with the same predecessor (Quadro Turing) and successor (Workstation Ada) in the database.

Specification Differences

The memory subsystems are entirely different in scale. The A6000 has 48 GB of GDDR6 memory on a 384-bit bus, delivering 768.0 GB/s of bandwidth. The A2000 12 GB has 12 GB of GDDR6 memory on a 192-bit bus, delivering 288.0 GB/s of bandwidth. The A6000 has four times the memory capacity and more than 2.6 times the memory bandwidth. The memory clock also differs: 2000 MHz (16 Gbps effective) on the A6000 versus 1500 MHz (12 Gbps effective) on the A2000 12 GB.

Clock speeds show a notable inversion. The A6000 has a base clock of 1410 MHz and a boost clock of 1800 MHz. The A2000 12 GB has a much lower base clock of 562 MHz and a boost clock of 1200 MHz. Despite the A2000 12 GB's lower clocks, its much smaller core count means it draws far less power: 70 W versus 300 W. The power connectors reflect this: the A6000 requires an 8-pin EPS connector and a 700 W suggested PSU, while the A2000 12 GB has no power connectors and only needs a 250 W suggested PSU.

Physical dimensions also differ. The A6000 is 267 mm (10.5 inches) long and 112 mm (4.4 inches) tall, while the A2000 12 GB is 167 mm (6.6 inches) long and 69 mm (2.7 inches) tall. Both are dual-slot cards. Display outputs differ as well: the A6000 offers 4x DisplayPort 1.4a, while the A2000 12 GB offers 4x mini-DisplayPort 1.4a. The A6000's launch MSRP is 4,649 USD, while the A2000 12 GB's launch MSRP is 449 USD.

Where Each One Wins

The NVIDIA RTX A6000 wins every recorded head-to-head benchmark in the database, and its advantages extend across every architectural metric. Its 10,752 shading units, 84 RT cores, and 336 tensor cores make it the clear choice for compute-heavy workloads such as rendering, simulation, and AI inference. The 48 GB memory capacity and 768.0 GB/s bandwidth allow it to handle datasets that would exceed the A2000 12 GB's 12 GB capacity, and the 38.71 TFLOPS FP32 output is roughly 4.8 times the A2000 12 GB's 7.987 TFLOPS. The A6000 also has a higher average benchmark score of 44,075 versus 34,154, a higher Passmark G3D score of 22,577, and a higher Passmark GPU Compute score of 14,110. Its 84th percentile ranking places it among the top tier of all GPUs in the database.

The A2000 12 GB wins in integration practicality. Its 70 W TDP means no external power connector is required, its 250 W suggested PSU rating allows installation in modest systems, and its 167 mm length makes it far easier to fit in compact chassis. The 12 GB memory capacity is still substantial for many workstation tasks, and its 79th percentile ranking shows it performs above the majority of GPUs tracked. Its 3DMark Steel Nomad DX12 score of 1,309 provides a ray-traced workload data point that the A6000 does not have recorded, though this is not a direct comparison. The A2000 12 GB is the card for users whose systems cannot support a 300 W, 267 mm dual-slot card, and whose workloads do not require the A6000's extreme compute and memory resources. The A6000 is the card for users who need maximum performance, maximum memory capacity, and maximum throughput, and who have the system power and space to accommodate it.
