NVIDIA RTX A2000 12 GB vs NVIDIA T600 Mobile Comparison

The NVIDIA RTX A2000 12 GB and the NVIDIA T600 Mobile are both end-of-life workstation GPUs, but they serve fundamentally different roles. The data places the RTX A2000 12 GB in a decisively higher performance class, while the T600 Mobile is a lower-power, more mobile-oriented part. Benchmark results indicate a complete victory for the RTX A2000 12 GB in the only shared test, with its average benchmark score of 34154 sitting 4.0% above the T600 Mobile's 32849. The RTX A2000 12 GB also holds a 79th percentile ranking among all GPUs, versus the 77th percentile for the T600 Mobile.

Head-to-Head Benchmarks

The only head-to-head benchmark result available directly compares the two GPUs in Geekbench OpenCL. In this test, the NVIDIA RTX A2000 12 GB scores 66998, while the NVIDIA T600 Mobile scores 35486. This represents a decisive 88.8% lead for the RTX A2000 12 GB. This is not a marginal win; it is a near-doubling of raw compute performance in a widely used compute API, indicating that the RTX A2000 12 GB is in a completely different performance tier.

The RTX A2000 12 GB also demonstrates its superiority through its average benchmark score. With an average score of 34154, it sits close to rivals like the NVIDIA RTX A1000 (34207, a -0.2% delta) and the NVIDIA TITAN V (34355, a -0.6% delta). This places it alongside much more expensive and larger desktop cards. In contrast, the T600 Mobile's average score of 32849 makes it a closer competitor to parts like the AMD Radeon RX 590 GME (32601, a 0.8% delta) and the AMD FirePro S9300 X2 (32540, a 0.9% delta), showing it is positioned firmly in the entry-level segment.

The wins tally is one for the RTX A2000 12 GB and zero for the T600 Mobile. The single Geekbench OpenCL result is the only direct comparison, but the delta is so substantial that it overshadows any potential other tests. The RTX A2000 12 GB's FP32 compute of 7.987 TFLOPS is more than three times the T600 Mobile's 2.527 TFLOPS, and its texture rate of 124.8 GTexel/s is 58% higher than the T600 Mobile's 78.96 GTexel/s. These figures reinforce the benchmark outcome, showing that the A2000's lead is consistent across theoretical and practical performance measures.

Where Each One Wins

The NVIDIA RTX A2000 12 GB wins in every category that matters for demanding workstation tasks. Its 12 GB of GDDR6 memory on a 192-bit bus provides 288.0 GB/s of bandwidth, a 50% advantage over the T600 Mobile's 4 GB and 192.0 GB/s. This is critical for large datasets, complex 3D scenes, and AI inference workloads. It also has dedicated RT cores (26) and Tensor cores (104), making it capable of hardware-accelerated ray tracing and AI processing. The T600 Mobile has no RT cores and no Tensor cores, meaning it must rely on less efficient compute paths for these tasks.

The NVIDIA T600 Mobile wins in the domain of power efficiency and system integration. Its TDP is 40 W, compared to the 70 W of the RTX A2000 12 GB. It is also an IGP (Integrated Graphics Processor) form factor, meaning it is designed for mobile workstations where space and cooling are at a premium. The RTX A2000 12 GB is a dual-slot card, requiring a full PCIe slot and dedicated cooling. The T600 Mobile uses a PCIe 3.0 x16 interface, while the RTX A2000 12 GB uses PCIe 4.0 x16; the older standard is sufficient for its lower bandwidth needs.

For users focused on portability or low-power systems, the T600 Mobile is the clear choice. Its 40 W power draw is nearly half of the A2000's, making it suitable for thin-and-light laptops without significant thermal throttling. It also has a higher base clock (780 MHz vs 562 MHz) and boost clock (1410 MHz vs 1200 MHz), which helps it deliver its lower performance envelope more responsively in short bursts. However, this does not compensate for the massive core-count and memory advantages of the RTX A2000 12 GB. The data shows that the T600 Mobile is a capable entry-level mobile GPU, but it cannot compete with the A2000 in sustained, heavy workloads.

Architecture Differences

The two GPUs are built on completely different architectures. The RTX A2000 12 GB uses the Ampere architecture (chip GA106), manufactured on an 8 nm process at Samsung. It packs 12,000 million transistors onto a 276 mm² die, achieving a transistor density of 43.5M per mm². The T600 Mobile uses the older Turing architecture (chip TU117), built on a 12 nm process at TSMC. It has 4,700 million transistors on a 200 mm² die, with a density of 23.5M per mm². The process node advantage is clear: the A2000 has more than double the transistor density, enabling far more compute units in a similar power envelope.

The RTX A2000 12 GB features 3328 shading units, 104 TMUs, and 48 ROPs. It also includes 26 RT cores and 104 Tensor cores, which are absent from the T600 Mobile. The T600 Mobile has only 896 shading units, 56 TMUs, and 32 ROPs. This is a 3.7x advantage in shading units for the A2000. The memory architecture also differs fundamentally: the A2000 uses a 192-bit bus with 12 GB GDDR6, while the T600 Mobile uses a 128-bit bus with 4 GB GDDR6. Both use 12 Gbps effective memory clocks, but the wider bus gives the A2000 a 288.0 GB/s bandwidth versus 192.0 GB/s.

API support also differs. The RTX A2000 12 GB supports DirectX 12 Ultimate (12_2), while the T600 Mobile supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The difference in DirectX feature level indicates that the A2000 is better suited for modern, DXR-enabled applications. The FP16 performance also tells a story: the A2000 delivers 7.987 TFLOPS (1:1 ratio), while the T600 Mobile delivers 5.053 TFLOPS (2:1 ratio). The A2000's 1:1 ratio is more efficient for compute workloads that use FP16, whereas the T600 Mobile's 2:1 ratio is a legacy design choice.

Specification Differences

The most obvious difference is the memory configuration. The RTX A2000 12 GB has 12 GB of GDDR6 memory, while the T600 Mobile has 4 GB. This is a 200% increase in memory capacity, directly impacting the size of datasets that can be processed in GPU memory. The bus widths are 192-bit and 128-bit, respectively, leading to bandwidth of 288.0 GB/s versus 192.0 GB/s.

The compute specifications are starkly different. The RTX A2000 12 GB has 3328 shading units, 104 TMUs, and 48 ROPs. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. The RTX A2000 12 GB also has 26 RT cores and 104 Tensor cores, while the T600 Mobile has none. The FP32 performance is 7.987 TFLOPS for the A2000 and 2.527 TFLOPS for the T600 Mobile. Pixel rates are 57.60 GPixel/s versus 45.12 GPixel/s, and texture rates are 124.8 GTexel/s versus 78.96 GTexel/s.

The form factors and power requirements diverge entirely. The RTX A2000 12 GB is a dual-slot card with a 70 W TDP and a suggested PSU of 250 W. It requires no power connectors and measures 167 mm in length and 69 mm in height. The T600 Mobile is an IGP with a 40 W TDP, no suggested PSU, and no dimensions listed. The RTX A2000 12 GB uses PCIe 4.0 x16, while the T600 Mobile uses PCIe 3.0 x16. Display outputs are also different: the A2000 has 4x mini-DisplayPort 1.4a, while the T600 Mobile's outputs are described as "Portable Device Dependent."

Other differences include the release dates and process nodes. The RTX A2000 12 GB was released on 2021-11-22, while the T600 Mobile was released on 2021-04-11. The A2000 uses an 8 nm Samsung process, and the T600 Mobile uses a 12 nm TSMC process. The T600 Mobile has a launch MSRP of null, while the RTX A2000 12 GB has a launch MSRP of 449 USD. The transistor counts are 12,000 million and 4,700 million, respectively.

The Verdict

The data is unambiguous: the NVIDIA RTX A2000 12 GB is the superior performer for any workstation task that requires compute, memory, or modern features. Its 88.8% lead in Geekbench OpenCL, combined with 12 GB of memory, RT cores, Tensor cores, and a 79th percentile ranking, makes it the clear choice for professionals running 3D rendering, AI inference, or large-scale data analysis. The T600 Mobile, with its 40 W TDP and IGP form factor, is strictly for mobile workstations where low power consumption is the priority over raw performance.

For users who need a desktop GPU for heavy workloads, the RTX A2000 12 GB is the only rational option. Its average benchmark score places it in the same league as the NVIDIA TITAN V, despite being a smaller, lower-power card. For users who require a mobile GPU for light CAD tasks or general productivity, the T600 Mobile is adequate, but it will struggle with any workload that benefits from CUDA cores or large memory footprints. The verdict is straightforward: pick the RTX A2000 12 GB for performance, and pick the T600 Mobile only if the system requires a 40 W mobile part.
