GPU Comparison

The NVIDIA Quadro K2000 and the NVIDIA RTX 5000 Mobile Ada Generation represent two extremes of the GPU spectrum: a legacy entry-level workstation card from 2013 and a modern, high-end mobile graphics processor from 2023. The data shows a generational chasm in specifications, but the benchmark results tell a more nuanced story that depends heavily on the metric used. The K2000 holds a slight edge in the Geekbench compute tests, while the RTX 5000 Mobile dominates in raw rasterization performance, as indicated by its 3DMark result. This analysis will break down the numbers to determine which card is relevant for specific workloads, using only our benchmark database.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The NVIDIA Quadro K2000 has a higher average benchmark score of 3964, compared to the RTX 5000 Mobile Ada Generation's average score of 3596. However, these scores are derived from different test suites, with the K2000's average coming from Geekbench Metal, OpenCL, and Vulkan tests, while the RTX 5000 Mobile's score is solely from the 3DMark Steel Nomad DX12 test.

Q: Is the RTX 5000 Mobile Ada Generation faster in DirectX 12 workloads?

A: Yes, the data strongly indicates this. The RTX 5000 Mobile scores 3596 in the 3DMark Steel Nomad DX12 benchmark. The K2000 has no corresponding 3DMark result, and its DirectX support is limited to version 12 (11_0), whereas the RTX 5000 Mobile supports DirectX 12 Ultimate (12_2).

Q: How does the Quadro K2000's memory bandwidth compare to the RTX 5000 Mobile's?

A: The RTX 5000 Mobile has a massive advantage, offering a memory bandwidth of 576.0 GB/s, which is nine times higher than the K2000's 64.00 GB/s. The RTX 5000 Mobile also has a 256-bit memory bus compared to the K2000's 128-bit bus.

Q: What is the difference in transistor count between the two GPUs?

A: The RTX 5000 Mobile's AD103 chip contains 45,900 million transistors, while the K2000's GK107 chip contains 1,270 million transistors. This makes the RTX 5000 Mobile's chip roughly 36 times more complex in terms of transistor count.

Q: Which GPU is positioned as end-of-life vs. active production?

A: The Quadro K2000 is marked as "End-of-life" in production status, with a release date of 2013-02-28. In contrast, the RTX 5000 Mobile Ada Generation is listed as "Active" and was released on 2023-03-20.

Q: Are these GPUs comparable in their nearest rival placements?

A: No. The K2000's nearest rivals are low-end mobile and desktop parts like the GeForce 830M and Radeon R5 M420, with very small deltas around 0.2-0.3%. The RTX 5000 Mobile's nearest rivals include the GeForce GTX 1050 and Radeon HD 6770, with larger deltas, including a -1.5% gap to the HD 6770.

The Verdict

The data presents a clear verdict: these are not competitors, but products for entirely different eras and use cases. The Quadro K2000, with its 24th percentile ranking, is a legacy part that still holds its own in specific compute benchmarks. Its average score of 3964 across Geekbench tests suggests it remains functional for older, compute-light tasks. However, its 2 GB of GDDR5 memory and 64.00 GB/s bandwidth are severely limiting by modern standards.

The RTX 5000 Mobile Ada Generation, despite its lower 21st percentile ranking based on a single benchmark, is the clear choice for any modern, graphics-intensive workload. Its 3DMark Steel Nomad DX12 score of 3596, while its only benchmark, indicates a level of rasterization performance that the K2000 cannot approach. The 16 GB of GDDR6 memory, 576.0 GB/s bandwidth, and support for DirectX 12 Ultimate make it the only viable option for current games, 3D rendering, or AI-adjacent tasks. For any builder looking at new workloads, the RTX 5000 Mobile is the only logical pick. The K2000 is a historical artifact, useful only for legacy systems or specific compute tasks where its Geekbench scores are relevant.

Head-to-Head Benchmarks

The head-to-head benchmark data is sparse, with no direct comparisons available. However, the existing benchmark suites provide a clear picture of where each wins.

K2000 Wins in Geekbench Compute:

The Quadro K2000 shows a decisive advantage in the Geekbench suite. It scores 3630 in Metal, 4071 in OpenCL, and 4191 in Vulkan. These results are consistent, with the Vulkan score being the highest. This indicates that for compute tasks leveraging these APIs, the K2000 is surprisingly competitive, likely due to its driver maturity for these specific legacy workloads. Its average score of 3964 places it ahead of its nearest rival, the AMD Radeon HD 6850 X2, by -0.3% (meaning the K2000 is faster), and it is 0.2% ahead of the GeForce 830M.

RTX 5000 Mobile Wins in 3DMark:

The RTX 5000 Mobile's only benchmark result is a 3DMark Steel Nomad DX12 score of 3596. This is a modern, demanding test that relies on DirectX 12 Ultimate features. The K2000 has no comparable score, and its older architecture with DirectX 12 (11_0) support would not be able to run this test effectively. This score of 3596 places it in a range with the GeForce GTX 1050, which scores 3629, a -0.9% delta, meaning the GTX 1050 is slightly faster. The data shows the RTX 5000 Mobile is in the same performance tier as a GTX 1050 in this specific test, which is a significant generational leap from the K2000.

Specification Differences

The specification gap between these two GPUs is immense, covering nearly every metric.

Architecture Differences

The architectural divide is fundamental, representing different eras of GPU design.

The Quadro K2000 is based on the Kepler architecture, a design from 2012. It is built on a 28 nm TSMC process. Its feature set is limited to the basics: it supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. It lacks any dedicated hardware for ray tracing or tensor operations. The K2000's predecessors are from the Quadro Fermi line, and it was succeeded by Quadro Maxwell. Its 384 shading units are organized in a legacy configuration that lacks the specialized cores found in modern GPUs.

In contrast, the RTX 5000 Mobile Ada Generation uses the Ada Lovelace architecture, built on a 5 nm process. This is a radically different design that includes 76 RT cores for ray tracing and 304 tensor cores for AI workloads. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The chip, AD103, is a massive 379 mm² die with 121.1M transistors per mm², reflecting the density improvements of modern manufacturing. It supports FP16 at a 1:1 ratio with FP32, both at 41.15 TFLOPS, enabling high-throughput compute. Its predecessor is Ampere-MW, and its successor is Blackwell-MW. This architecture is designed for real-time ray tracing, DLSS, and other modern features that the Kepler architecture cannot handle.

Where Each One Wins

The Quadro K2000 wins in legacy compute scenarios. Its Geekbench scores are its strong suit. Data shows it scores 4191 in Vulkan, 4071 in OpenCL, and 3630 in Metal. This suggests it can still be relevant for specific, older compute applications that rely on these APIs and do not require large memory pools or modern features. It is also the only option for systems that require a physical, single-slot, 51 W card with a DVI output. Its 24th percentile ranking indicates it is a low-tier performer, but for its niche, it is functional.

The RTX 5000 Mobile Ada Generation wins in every modern workload. Its 3DMark Steel Nomad DX12 score of 3596, while not top-tier (given its 21st percentile), represents a level of rasterization performance that is entirely out of reach for the K2000. The 16 GB of GDDR6 memory is essential for modern textures and datasets. The 576.0 GB/s bandwidth ensures that data flows quickly to the 9728 shading units. The inclusion of 76 RT cores and 304 tensor cores makes it suitable for ray-traced rendering and AI-accelerated tasks, which are impossible on the K2000. For gaming, 3D modeling, video editing, or any task that uses DirectX 12 Ultimate, the RTX 5000 Mobile is the definitive winner. Its 120 W TDP is higher than the K2000, but it is an IGP, meaning it is integrated into a laptop or mobile workstation, making it a self-contained solution for portable performance.
