NVIDIA RTX 2000 Ada Generation vs NVIDIA T400 4 GB Comparison

The NVIDIA RTX 2000 Ada Generation and the NVIDIA T400 4 GB occupy very different tiers of the workstation GPU spectrum. The data shows a decisive performance gap between them, with the RTX 2000 Ada Generation winning both recorded head-to-head benchmarks by margins exceeding 350%. The T400 4 GB is an end-of-life product from the Turing generation, while the RTX 2000 Ada Generation is an active Ada Lovelace part with a 5 nm process node and significantly newer architecture fundamentals.

The Verdict

The RTX 2000 Ada Generation is the clear winner in raw performance metrics across every measurable category. It holds a 63rd percentile rank among all GPUs in the database, compared to a 60th percentile for the T400 4 GB. Its average benchmark score is 18954, which places it within 0.5% of the NVIDIA Quadro K6000 and within 0.5% of the GeForce RTX 4050 Mobile. The T400 4 GB, by contrast, averages 16792, sitting within 0.6% of the AMD Radeon RX 7600S and 0.8% below the NVIDIA Tesla M4.

In the two shared benchmarks, the RTX 2000 Generation is 350.8% ahead in Geekbench OpenCL and 412.6% ahead in Geekbench Vulkan. These margins are not incremental improvements but generational leaps in capability. The RTX 2000 Generation offers a 12.00 TFLOPS FP32 compute rate versus 1,094.4 GFLOPS for the T400 4 GB, a scale difference of roughly 11 times. For users requiring professional workloads that demand high compute throughput, the RTX 2000 Ada Generation is the only defensible choice based on these numbers.

The T400 4 GB, with its 30 W TDP, single-slot design, and no power connectors, might appear attractive only in scenarios where space and power constraints are extreme. However, the data does not include benchmarks that would validate such a tradeoff. The RTX 2000 Generation carries a 70 W TDP and dual-slot form factor. Neither part requires external power connectors, but the RTX 2000 Generation does suggest a 250 W power supply versus 200 W for the T400 4 GB. The verdict from the recorded data is straightforward: the RTX 2000 Ada Generation wins on every head-to-head metric, and the T400 is a legacy product with a fraction of the compute resources.

Architecture Differences

The architectural gap is substantial. The RTX 2000 Ada Generation uses the AD107 chip built on TSMC's 5 nm process, containing 18,900 million transistors on a 159 mm² die. The T400 4 GB uses the TU117 chip on a 12 nm process, with 4,700 million transistors on a 200 mm² die. This means the Ada part packs roughly 4 times more transistors into a smaller physical area, yielding a transistor density of 118.9M per mm² versus 23.5M per mm² for the Turing chip. The process node advantage is the foundation of the performance difference.

The RTX 2000 Generation features 2816 shading units, 88 texture mapping units, and 48 ROPs. It includes 22 RT cores and 88 tensor cores, enabling hardware-accelerated ray tracing and AI workloads. The T400 4 GB has only 384 shading units, 24 TMUs, and 16 ROPs, with no RT cores and no tensor cores listed. The absence of these specialized units means the T400 cannot accelerate ray tracing or tensor operations in hardware, a fundamental feature difference.

Memory architecture also diverges sharply. The RTX 2000 Generation has 16 GB of GDDR6 memory on a 128 bit bus, delivering 256.0 GB/s of bandwidth. The T400 4 GB has 4 GB of GDDR6 on a 64 bit bus, delivering 80.00 GB/s. The RTX 2000 Generation also supports DirectX 12 Ultimate (12_2), while the T400 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX 2000 Generation uses a PCIe 4.0 x8 interface, while the T400 uses PCIe 3.0 x16. The RTX 2000 Generation offers 4 display outputs versus 3 for the T400, both using mini-DisplayPort 1.4a.

Head-to-Head Benchmarks

The database records two shared benchmark tests between these cards, and both show overwhelming wins for the RTX 2000 Ada Generation. In Geekbench OpenCL, the RTX 2000 Generation scores 78074 against 17320 for the T400 4 GB, a delta of 350.8%. This is the compute-oriented test, and the gap reflects the massive difference in shading units, memory bandwidth, and raw FP32 throughput. The T400's FP32 rate of 1,094.4 GFLOPS is simply not competitive with 12.00 TFLOPS.

In Geekbench Vulkan, the RTX 2000 Generation scores 83360 versus 16263 for the T400 4 GB, a delta of 412.6%. This is the larger margin of the two tests. The Vulkan result may reflect the RTX 2000 Generation's newer architecture, its DirectX 12 Ultimate feature set, and its higher memory bandwidth. The T400's Vulkan score of 16263 is actually lower than its own OpenCL score of 17320, while the RTX 2000 Generation scores higher in Vulkan (83360) than in OpenCL (78074).

The RTX 2000 Generation's average benchmark score of 18954 places it just 0.4% below the AMD Radeon RX 6600 and just 0.4% below the Quadro K6000, indicating it sits in a competitive performance tier. The T400 4 GB's average of 16792 places it 1.4% below the GeForce GTX 690 and 1.3% below the AMD Radeon HD 7970M, showing it competes with much older hardware. The delta between the two cards' average scores is 2162 points, or roughly 12.9% of the T400's average, but the head-to-head deltas are far larger, indicating the T400's relative strength may lie in legacy workloads not captured by the shared tests.

FAQ

Where Each One Wins

The RTX 2000 Ada Generation wins in every recorded category. In the two shared benchmark tests, it holds a 350.8% advantage in Geekbench OpenCL and a 412.6% advantage in Geekbench Vulkan. Its 12.00 TFLOPS FP32 rate makes it suitable for compute-heavy workloads such as GPU rendering, scientific simulation, or machine learning inference, especially with its 88 tensor cores. Its 16 GB memory capacity and 256.0 GB/s bandwidth support larger datasets and higher resolution textures than the T400's 4 GB and 80.00 GB/s.

The T400 4 GB has no benchmark wins in the database. Its advantages are limited to physical characteristics: a 30 W TDP versus 70 W, a single-slot form factor versus dual-slot, and a 200 W suggested PSU versus 250 W. The T400's 12 nm process and 4,700 million transistors are substantially older and smaller in count than the RTX 2000 Generation's 5 nm process and 18,900 million transistors. For computing tasks, the T400's 384 shading units and 1,094.4 GFLOPS FP32 rate place it in a fundamentally lower performance class. Its 4 GB memory and 64 bit bus will bottleneck any memory-intensive workload.

The data does not support any use case where the T400 4 GB outperforms the RTX 2000 Ada Generation. In environments where power draw below 30 W is non-negotiable, the T400 is the only option between these two, but no performance data in the database validates such a tradeoff. For every measurable workload, the RTX 2000 Generation is the superior choice.
