NVIDIA GeForce RTX 3080 Ti vs NVIDIA RTX A2000 Comparison

The NVIDIA RTX A2000 and the NVIDIA GeForce RTX 3080 Ti represent two very different interpretations of the Ampere architecture, and the benchmark data reflects that divergence clearly. While both cards share a common DNA, their positioning—one for professional workstations, the other for high-end consumer graphics—results in a performance gap that dominates every head-to-head comparison. The data shows a decisive victory for the GeForce card, but the A2000's existence is justified by factors beyond raw frame rates.

Head-to-Head Benchmarks

The benchmark results are unambiguous in their verdict. Across all three shared tests, the NVIDIA GeForce RTX 3080 Ti delivers a commanding performance advantage, with margins that range from substantial to overwhelming. The largest disparity appears in the 3DMark Steel Nomad DX12 test, a demanding modern workload. Here, the RTX 3080 Ti scores 5077, while the RTX A2000 manages only 1345. This represents a delta of -73.5% for the A2000, meaning the GeForce card is roughly 3.8 times faster in this specific metric. This is not a close contest; it is a generational gap in execution resources.

The compute-oriented benchmarks tell a similar story, albeit with slightly narrower margins. In Geekbench OpenCL, the RTX 3080 Ti posts a score of 170037, dwarfing the A2000's 67695. The delta here is -60.2%, indicating the GeForce card is about 2.5 times more capable in this parallel compute workload. The Vulkan results follow the same trend, with the RTX 3080 Ti achieving 192697 against the A2000's 69089, a -64.1% difference. The consistency of these results across different APIs and workload types suggests that the RTX 3080 Ti's advantage is fundamental to its hardware design, not an artifact of any single test.

Interestingly, the average benchmark scores paint a slightly different picture of overall positioning. The RTX A2000 has an average benchmark score of 46043, while the RTX 3080 Ti's average is 41187. This inversion occurs because the A2000's average is drawn from its three included tests, while the RTX 3080 Ti's average includes several additional Passmark tests with lower scores, such as Passmark DirectX 9 at 274 and Passmark G2D at 1091. When looking at the shared benchmarks only, the RTX 3080 Ti's dominance is absolute. The percentile rankings also show nuance: the A2000 sits at the 85th percentile of all GPUs, while the RTX 3080 Ti sits at the 83rd, despite the latter's far higher peak scores. This suggests the A2000's overall performance profile is more consistent across a wider range of tasks, even if it cannot match the GeForce card's peak output.

Where Each One Wins

The data clearly shows that the NVIDIA GeForce RTX 3080 Ti wins in every single head-to-head benchmark category. There are zero wins for the RTX A2000 in the shared test suite. The GeForce card's victories are not marginal either; they are decisive across DirectX 12, OpenCL, and Vulkan workloads. This indicates that for any task that scales with raw computational throughput—be it gaming, 3D rendering, or GPU compute—the RTX 3080 Ti is the superior choice.

However, the RTX A2000's strengths lie outside the raw score comparisons. Its 70 W TDP is a fraction of the RTX 3080 Ti's 350 W, and it requires no external power connectors, drawing all its power from the PCIe slot. This makes it a far more flexible option for compact systems, low-power workstations, or multi-GPU configurations where power delivery and thermal dissipation are critical constraints. The A2000's dual-slot, 167 mm length also contrasts sharply with the RTX 3080 Ti's 285 mm length, making the A2000 suitable for chassis that cannot physically accommodate a large graphics card. In scenarios where space, power, and cooling are at a premium, the A2000's design philosophy wins, even if its benchmark scores do not.

Q: How do their percentile rankings compare?

A: The RTX A2000 is at the 85th percentile of all GPUs, and the RTX 3080 Ti is at the 83rd percentile. Despite the RTX 3080 Ti's higher peak performance, the A2000 ranks higher in overall percentile.

Q: What is the TDP difference between the two cards?

A: The RTX A2000 has a TDP of 70 W, while the RTX 3080 Ti has a TDP of 350 W. The A2000 also requires no external power connectors, whereas the RTX 3080 Ti uses a 1x 12-pin connector.

Specification Differences

The specification sheets reveal a stark contrast in nearly every measurable category. The most obvious difference is in memory: the RTX A2000 offers 6 GB of GDDR6 on a 192-bit bus, while the RTX 3080 Ti provides 12 GB of GDDR6X on a 384-bit bus. This translates to a bandwidth of 288.0 GB/s for the A2000 versus 912.4 GB/s for the RTX 3080 Ti. The memory clock speeds also differ, with the A2000 running at 1500 MHz (12 Gbps effective) and the RTX 3080 Ti at 1188 MHz (19 Gbps effective).

The compute resources are equally disparate. The RTX A2000 has 3328 shading units, 104 TMUs, and 48 ROPs. The RTX 3080 Ti, in contrast, has 10240 shading units, 320 TMUs, and 112 ROPs. This 3:1 ratio in shading units is a primary driver of the performance gap. The RT and tensor core counts follow suit: the A2000 has 26 RT cores and 104 tensor cores, while the RTX 3080 Ti has 80 RT cores and 320 tensor cores. The resulting fill rates and compute throughputs diverge sharply, with the RTX 3080 Ti achieving 186.5 GPixel/s and 532.8 GTexel/s, versus the A2000's 57.60 GPixel/s and 124.8 GTexel/s. FP32 performance is 34.10 TFLOPS for the GeForce card and 7.987 TFLOPS for the A2000.

Physical specifications also differ. The RTX A2000 is 167 mm long and 69 mm high, while the RTX 3080 Ti is 285 mm long, 112 mm high, and 40 mm wide. The A2000 has no power connectors, while the RTX 3080 Ti requires a 1x 12-pin connector. The suggested PSU is 250 W for the A2000 and 750 W for the RTX 3080 Ti. Display outputs differ as well: the A2000 offers 4x mini-DisplayPort 1.4a, while the RTX 3080 Ti has 1x HDMI 2.1 and 3x DisplayPort 1.4a.

Architecture Differences

Both cards are built on NVIDIA's Ampere architecture, fabricated on an 8 nm process at Samsung. However, they use different chips that belong to different tiers of the Ampere lineup. The RTX A2000 is based on the GA106 chip, while the RTX 3080 Ti uses the GA102 chip. This is a fundamental difference, as the GA102 is a much larger and more complex die.

The transistor counts reflect this disparity. The GA106 in the A2000 contains 12,000 million transistors on a 276 mm² die. The GA102 in the RTX 3080 Ti contains 28,300 million transistors on a 628 mm² die. The transistor density is similar—43.5M per mm² for the A2000 and 45.1M per mm² for the RTX 3080 Ti—but the sheer scale of the GA102 provides far more execution resources. The A2000 belongs to the Workstation Ampere (Ax000) generation, while the RTX 3080 Ti belongs to the GeForce 30 series. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level features are identical. The release dates are close, with the RTX 3080 Ti launching on 2021-05-30 and the A2000 on 2021-08-09.

The Verdict

The data is unequivocal: for pure performance, the NVIDIA GeForce RTX 3080 Ti is the superior product. It wins every head-to-head benchmark by a massive margin, offers double the memory capacity with more than triple the bandwidth, and delivers over four times the FP32 compute throughput. Any user whose primary concern is raw speed in rendering, gaming, or compute should choose the RTX 3080 Ti without hesitation. The benchmark results show it is in a completely different performance class.

The NVIDIA RTX A2000, however, has a clear role for a specific type of user. Its 70 W TDP and lack of power connectors make it ideal for systems where power delivery is limited or where thermal output must be minimized. Its compact 167 mm length allows it to fit in small form factor cases. The higher average benchmark score and 85th percentile ranking suggest it offers a more balanced performance profile across diverse workloads. For a professional needing a low-profile, efficient card for a workstation that handles varied tasks without requiring peak performance, the A2000 is the sensible pick. The choice is not about which card is better in absolute terms; it is about which card's characteristics align with the user's physical and power constraints. The RTX 3080 Ti is for those who need maximum speed, while the A2000 is for those who need maximum flexibility.
