NVIDIA RTX A1000 vs NVIDIA RTX A6000 Comparison

Head-to-Head Benchmarks

The benchmark data is unambiguous: the NVIDIA RTX A6000 dominates the NVIDIA RTX A1000 in every recorded head-to-head test, with margins that are substantial enough to classify these as different performance tiers entirely. The database records only two overlapping benchmark tests between the two cards, and the RTX A6000 wins both by a wide margin.

In the Geekbench OpenCL test, the RTX A6000 scores 193,937 points against the RTX A1000's 52,078 points. That is a 272.4% advantage, meaning the A6000 delivers nearly four times the compute performance in this workload. This is not a marginal gap; it is a generational chasm in raw throughput. The OpenCL benchmark stresses general-purpose GPU compute, including floating-point operations and memory bandwidth, areas where the A6000's hardware resources are vastly larger.

The Geekbench Vulkan test shows a similar pattern. The RTX A6000 posts 164,462 points, while the RTX A1000 manages 49,574 points. The delta here is 231.8% in favor of the A6000. Vulkan is a low-level graphics and compute API, and the A6000's advantage persists even in this lighter-weight driver environment. The consistent margin across both APIs suggests the performance gap is structural rather than workload-specific.

Looking at the broader database averages, the RTX A6000 holds an average benchmark score of 44,075, while the RTX A1000's average is 34,207. That places the A6000 in the 84th percentile of all GPUs, versus the A1000's 79th percentile. The percentile difference is smaller than the raw score gap because many other cards sit between them, but the ranking is clear: the A6000 is a high-tier workstation card, while the A1000 sits in the upper-middle tier.

The RTX A6000's nearest rivals in the database include the GeForce RTX 4090 Mobile (average score 43,667, a 0.9% delta), the GeForce RTX 4070 Ti (average score 44,795, a -1.6% delta), the Quadro M6000 (average score 43,301, a 1.8% delta), and the GeForce RTX 5050 Mobile (average score 43,268, a 1.9% delta). These deltas are all within 2%, showing that the A6000 is tightly clustered with these high-end parts. The RTX A1000, meanwhile, sits within 0.6% of the RTX A2000 12 GB, the AMD Radeon RX 560 XT, and the AMD Radeon RX 480, with a -0.4% delta against the NVIDIA TITAN V. The A1000's performance neighborhood is populated by mid-range and previous-generation flagship cards.

The Verdict

The recorded data supports a single, clear conclusion: the NVIDIA RTX A6000 is the superior workstation GPU in every measured category. It wins both head-to-head benchmarks, holds a higher average benchmark score, and ranks in the 84th percentile versus the A1000's 79th. For any workload that relies on raw compute throughput or Vulkan-based rendering, the A6000 is the definitive choice.

The RTX A6000's compute advantage is staggering. In OpenCL, it is 272.4% ahead of the A1000, and in Vulkan it is 231.8% ahead. Those numbers translate to real-world productivity: tasks that take three hours on the A1000 can take roughly one hour on the A6000, assuming linear scaling. The A6000's memory subsystem, with 48 GB of GDDR6 and 768.0 GB/s of bandwidth, is in a different league from the A1000's 8 GB and 192.0 GB/s. The data shows that the A6000 is built for large datasets and memory-hungry compute workloads.

However, the verdict is not universally "buy the A6000." The RTX A1000 is the only one of the two with an active production status; the RTX A6000 is listed as end-of-life. That status has practical implications for availability and long-term support, even if it does not affect the benchmark scores. The A1000 also requires no external power connectors and has a 50 W TDP, versus the A6000's 300 W TDP with an 8-pin EPS connector. The A6000 demands a 700 W suggested PSU, while the A1000 operates with a 250 W suggestion. For systems with strict power and thermal limits, the A1000 is the only feasible option. The A6000 is a dual-slot card at 267 mm length and 112 mm height; the A1000 is single-slot at 163 mm and 69 mm. If physical space is the constraint, the A1000 wins.

Where Each One Wins

The RTX A6000 wins in every benchmark contest recorded between the two. Its wins are in OpenCL compute and Vulkan rendering, and the margins are 272.4% and 231.8%, respectively. The A6000's 38.71 TFLOPS FP32 and FP16 performance, combined with 84 RT cores and 336 tensor cores, make it a heavy-duty compute engine. Its 48 GB memory capacity and 768.0 GB/s bandwidth position it for large-scale scientific computing, AI model training, and high-resolution rendering where data exceeds the A1000's 8 GB limit.

The RTX A1000 wins in the practical categories of power and footprint. Its 50 W TDP and no power connectors mean it can be installed in machines with modest power supplies, and its single-slot, 163 mm length fits into small chassis. The A1000's 6.737 TFLOPS FP32 performance is still respectable for entry-level workstation tasks, but the data shows it is 82.6% slower than the A6000 in raw FP32 throughput. The A1000's PCIe 4.0 x8 interface is half the lane width of the A6000's PCIe 4.0 x16, which could impact data-transfer-heavy workloads, though the benchmark results do not isolate this.

For users who need a passive, low-power card for a compact system, the A1000 is the only choice between these two. For users who need maximum compute and have the power budget, the A6000 is the only choice. There is no middle ground in the measured data.

Architecture Differences

Both GPUs are built on the same NVIDIA Ampere architecture and the same Samsung 8 nm process node, but they are fundamentally different chips. The RTX A6000 uses the GA102 chip, which is the large Ampere die. The RTX A1000 uses the GA107 chip, which is a smaller, power-efficient part.

The transistor counts are stark. The A6000 packs 28,300 million transistors on a 628 mm² die, for a transistor density of 45.1 million per mm². The A1000 has 8,700 million transistors on a 200 mm² die, with a density of 43.5 million per mm². The density is similar, but the A6000 has over 3.2 times the transistor count and over 3.1 times the die area. This explains the massive performance difference: the A6000 has 10,752 shading units, 336 TMUs, and 112 ROPs, versus the A1000's 2,304 shading units, 72 TMUs, and 32 ROPs. The A6000 also carries 84 RT cores and 336 tensor cores, while the A1000 has 18 RT cores and 72 tensor cores.

The memory subsystem is another architectural separator. The A6000 uses a 384-bit memory bus with a 2000 MHz memory clock and 16 Gbps effective speed. The A1000 uses a 128-bit bus with a 1500 MHz clock and 12 Gbps effective speed. This is why the A6000 delivers 768.0 GB/s of bandwidth versus the A1000's 192.0 GB/s. The A6000 also supports PCIe 4.0 x16, while the A1000 uses PCIe 4.0 x8, halving the host interface bandwidth.

The FP32 and FP16 throughput is also a major difference. The A6000 achieves 38.71 TFLOPS in both FP32 and FP16 (1:1 ratio), while the A1000 achieves 6.737 TFLOPS in both. That means the A6000 has 5.7 times the single-precision compute. Pixel rate and texture rate follow suit: the A6000 has 201.6 GPixel/s and 604.8 GTexel/s, versus the A1000's 46.78 GPixel/s and 105.3 GTexel/s. These architectural differences are the root cause of the benchmark deltas.

The A6000 is fabricated on 8 nm at Samsung with 28,300 million transistors and a 628 mm² die. The A1000 is also 8 nm at Samsung, but has 8,700 million transistors and a 200 mm² die. Transistor density is 45.1M / mm² for the A6000 and 43.5M / mm² for the A1000.

Clock speeds differ: the A6000 has a base clock of 1410 MHz, boost of 1800 MHz, and memory clock of 2000 MHz (16 Gbps effective). The A1000 has a base clock of 727 MHz, boost of 1462 MHz, and memory clock of 1500 MHz (12 Gbps effective). The memory configuration is 48 GB GDDR6 with 384-bit bus for the A6000 versus 8 GB GDDR6 with 128-bit bus for the A1000.

Compute resources: the A6000 has 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The A1000 has 2,304 shading units, 72 TMUs, 32 ROPs, 18 RT cores, and 72 tensor cores. The A6000's pixel rate is 201.6 GPixel/s and texture rate is 604.8 GTexel/s; the A1000's are 46.78 GPixel/s and 105.3 GTexel/s, respectively. FP32 and FP16 performance are 38.71 TFLOPS each for the A6000 versus 6.737 TFLOPS each for the A1000.

Power and physical differences: the A6000 has a 300 W TDP, dual-slot width, and requires an 8-pin EPS connector with a 700 W suggested PSU. The A1000 has a 50 W TDP, single-slot width, and requires no power connector with a 250 W suggested PSU. The A6000 measures 267 mm (10.5 inches) in length and 112 mm (4.4 inches) in height; the A1000 measures 163 mm (6.4 inches) and 69 mm (2.7 inches). The bus interface is PCIe 4.0 x16 for the A6000 versus PCIe 4.0 x8 for the A1000. Display outputs are 4x DisplayPort 1.4a for the A6000 versus 4x mini-DisplayPort 1.4a for the A1000. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A6000 was released on 2020-10-04 with a launch MSRP of 4,649 USD, while the A1000 was released on 2024-04-15 with no launch MSRP recorded.
