NVIDIA RTX A6000 vs NVIDIA T1000 Comparison

Where Each One Wins

The recorded data splits these two workstation GPUs into completely different performance tiers. The NVIDIA RTX A6000 wins every single head-to-head benchmark in the database, taking both available tests. The NVIDIA T1000 records zero wins against the A6000. This is not a close contest; it is a category gap.

The RTX A6000 dominates in compute-heavy workloads. In Geekbench OpenCL, the A6000 scores 193,937 against the T1000’s 37,704, a delta of 414.4 percent. That is a fivefold advantage in raw compute throughput. For Vulkan workloads, the A6000 posts 164,462 versus the T1000’s 34,874, a 371.6 percent delta. Any task that relies on GPU compute, such as rendering, simulation, or data processing, will favor the A6000 overwhelmingly.

The T1000’s role is different. It is a low-power, compact workstation card for basic visualization and multi-display setups. The database shows it has no benchmark wins over the A6000, but its niche is not about winning performance contests. With a 50 W power draw and single-slot design, the T1000 fits into small form factor workstations where the A6000’s 300 W requirement and dual-slot footprint would not be practical. The T1000 also uses PCIe 3.0 x16, while the A6000 uses PCIe 4.0 x16, making the T1000 suitable for older systems.

For users who need maximum GPU compute, the choice is obvious. The A6000 sits at the 84th percentile of all GPUs in the database, while the T1000 sits at the 80th. The average benchmark score tells the same story: 44,075 for the A6000 versus 36,289 for the T1000. The A6000 is closer in performance to the GeForce RTX 4090 Mobile (0.9 percent ahead), the RTX 4070 Ti (1.6 percent behind), and the Quadro M6000 (1.8 percent ahead). The T1000, by contrast, trades blows with the Radeon RX 5300M (0.7 percent behind), the GeForce GTX TITAN X (0.7 percent behind), and the Radeon Pro Duo (1.2 percent ahead).

Architecture Differences

The two cards come from different GPU generations and foundries. The RTX A6000 uses the GA102 chip on Samsung’s 8 nm process, while the T1000 uses the TU117 chip on TSMC’s 12 nm process. The A6000 belongs to the Workstation Ampere generation, and the T1000 belongs to the Quadro Turing generation. This generational gap explains much of the performance difference.

Transistor counts reinforce the divide. The A6000 packs 28,300 million transistors on a 628 mm² die, giving a density of 45.1 million transistors per mm². The T1000 has 4,700 million transistors on a 200 mm² die, with a density of 23.5 million per mm². The A6000 has six times the transistor budget and a die over three times larger.

Core configuration is equally lopsided. The A6000 carries 10,752 shading units, 336 texture mapping units, and 112 render output units. The T1000 has 896 shading units, 56 TMUs, and 32 ROPs. The A6000 also includes 84 RT cores and 336 tensor cores, while the T1000 has none listed for either. That means the T1000 cannot accelerate ray tracing or tensor operations in hardware, while the A6000 is fully equipped for both.

Clock speeds favor the A6000 as well. Its base clock is 1410 MHz with a boost of 1800 MHz. The T1000 runs at 1065 MHz base and 1395 MHz boost. Memory clocks differ sharply: the A6000 runs at 2000 MHz with 16 Gbps effective speed, while the T1000 runs at 1250 MHz with 10 Gbps effective. The A6000 delivers 768.0 GB/s of bandwidth across a 384-bit bus, versus the T1000’s 160.0 GB/s on a 128-bit bus. Memory capacity is 48 GB of GDDR6 for the A6000 versus 4 GB for the T1000, a twelvefold difference.

The feature set also diverges. The A6000 supports DirectX 12 Ultimate (12_2), while the T1000 only reaches DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The A6000 outputs via four DisplayPort 1.4a connectors; the T1000 uses four mini-DisplayPort 1.4a connectors. The A6000 is dual-slot with an 8-pin EPS power connector and a suggested 700 W PSU. The T1000 is single-slot, draws power from the PCIe slot only, and needs just a 250 W PSU. Physically, the A6000 measures 267 mm in length, while the T1000 is 156 mm.

Head-to-Head Benchmarks

The database records two direct comparisons between these cards, and the A6000 wins both by enormous margins. In Geekbench OpenCL, the A6000 scores 193,937 against the T1000’s 37,704. The delta is 414.4 percent, meaning the A6000 delivers more than five times the OpenCL compute performance. This test stresses general-purpose GPU computation, so the A6000’s massive core count and memory bandwidth translate directly into a dominant result.

In Geekbench Vulkan, the A6000 scores 164,462 against the T1000’s 34,874. The delta is 371.6 percent, a slightly smaller but still overwhelming advantage. Vulkan workloads benefit from the A6000’s newer architecture and higher memory throughput. The T1000’s Turing architecture, while competent for its class, simply cannot keep pace with Ampere’s full-size GA102 die.

Looking at the broader benchmark suite, the A6000 has additional scores that the T1000 lacks in this database. The A6000 records 22,577 in PassMark G3D, 14,110 in PassMark GPU Compute, 913 in PassMark G2D, and various DirectX scores: 245 in DirectX 9, 191 in DirectX 11, 155 in DirectX 10, and 87 in DirectX 12. The T1000 has no recorded PassMark or DirectX scores in the database, so no direct comparison is possible for those tests. Still, the two Geekbench results paint a clear picture: the A6000 is in a different performance class entirely.

The A6000’s average benchmark score of 44,075 places it just above the GeForce RTX 4090 Mobile (43,667, a 0.9 percent advantage) and just below the RTX 4070 Ti (44,795, a 1.6 percent deficit). The T1000’s average of 36,289 sits near the Radeon RX 5300M (36,529, a 0.7 percent deficit) and the GeForce GTX TITAN X (36,530, a 0.7 percent deficit). In other words, the A6000 competes with top-tier consumer GPUs, while the T1000 matches older or mid-range parts.

The Verdict

The data makes the decision straightforward for compute-heavy workloads. The NVIDIA RTX A6000 is the clear choice for any task that demands raw GPU performance. Its 414.4 percent lead in OpenCL and 371.6 percent lead in Vulkan over the T1000 are decisive. With 48 GB of memory, 768.0 GB/s of bandwidth, 10,752 shading units, and support for ray tracing and tensor cores, the A6000 is built for serious workstation duties. Its 84th percentile ranking and average score of 44,075 put it in the same class as the GeForce RTX 4090 Mobile and RTX 4070 Ti, making it a top-tier part in the database.

The NVIDIA T1000 serves a different purpose. It is a 50 W, single-slot card that needs no external power and fits in compact systems. Its 4 GB memory and 160.0 GB/s bandwidth are sufficient for basic visualization and display tasks, but not for intensive compute. The T1000’s 80th percentile ranking and average score of 36,289 place it near the Radeon RX 5300M and GeForce GTX TITAN X, which are older or lower-tier parts. For users with space and power constraints, the T1000 is a reasonable option. For anyone who needs performance, the A6000 wins without contest.

The release timeline also matters. The A6000 launched on 2020-10-04, while the T1000 arrived later on 2021-05-05. Despite being older, the A6000 is the more capable card. Both are end-of-life products, but the A6000’s successor is listed as Workstation Ada, while the T1000’s successor is Workstation Ampere. That means the T1000’s replacement is the very architecture the A6000 belongs to, further highlighting the performance hierarchy. Choose the A6000 for compute, choose the T1000 for low-power simplicity. The benchmark results do not suggest any other conclusion.
