NVIDIA Quadro K2100M vs NVIDIA RTX 5000 Mobile Ada Generation Comparison

The NVIDIA Quadro K2100M and the NVIDIA RTX 5000 Mobile Ada Generation represent two distant points in NVIDIA’s mobile professional GPU timeline. The K2100M is a Kepler-era part from 2013, built for workstation laptops of that generation, while the RTX 5000 Mobile Ada is a current Ada Lovelace design aimed at high-end mobile workstations. The database shows a stark contrast in raw performance, feature support, and architectural design, though the recorded benchmark scores tell a nuanced story when placed against their respective peers.

Head-to-Head Benchmarks

Direct head-to-head results between these two GPUs are not recorded in the database, so the comparison relies on their individual benchmark averages and how each sits within its own competitive set.

The Quadro K2100M has an average benchmark score of 4151 across three recorded tests: Geekbench Metal at 3524, Geekbench OpenCL at 4587, and Geekbench Vulkan at 4343. Its nearest rivals in the database include the AMD Radeon R5 M330 with an average score of 4170, the NVIDIA GeForce GTX 1050 Ti at 4193, the AMD Radeon RX 9060 XT 8 GB at 4093, and the Intel HD Graphics 630 at 4075. The delta percentages are tight: the K2100M sits 0.4% behind the Radeon R5 M330, 1% behind the GTX 1050 Ti, 1.4% ahead of the Radeon RX 9060 XT 8 GB, and 1.9% ahead of the Intel HD Graphics 630. This clustering indicates that the K2100M’s average score is nearly indistinguishable from these very different GPUs, a sign that its performance level is roughly mid-pack among older and entry-level parts.

The RTX 5000 Mobile Ada Generation has a single recorded benchmark: 3DMark Steel Nomad DX12 with a score of 3596. Its nearest rivals are the NVIDIA GeForce GT 545 at 3594, the NVIDIA GeForce GT 735M at 3616, the NVIDIA GeForce GTX 1050 at 3629, and the AMD Radeon HD 6770 at 3649. The deltas are similarly small: 0.1% ahead of the GT 545, 0.6% behind the GT 735M, 0.9% behind the GTX 1050, and 1.5% behind the Radeon HD 6770. This is a surprising result for a modern high-end mobile chip, but it reflects the specific workload of the Steel Nomad test, which is a demanding DX12 benchmark that may not favor the RTX 5000’s architecture in this particular metric. The data shows that in this single test, the RTX 5000 Mobile Ada lands in the same performance neighborhood as much older desktop and mobile GPUs.

Directly comparing the two averages, the K2100M’s 4151 is 15.4% higher than the RTX 5000’s 3596. However, the tests used are entirely different: the K2100M’s average is drawn from Geekbench compute tests (Metal, OpenCL, Vulkan), while the RTX 5000’s score comes from a 3DMark DX12 workload. The database does not provide a common benchmark where both GPUs were measured, so any numerical comparison across these averages must account for the mismatch in test methodology. The K2100M’s Geekbench scores are all above 3500, with OpenCL leading at 4587, while the RTX 5000’s only recorded result is 3596 in Steel Nomad. Without overlapping tests, the data cannot show which GPU is faster in a head-to-head sense; it only shows how each performs relative to its own rivals.

Architecture Differences

The architectural gap is massive. The K2100M uses the GK106S chip based on the Kepler architecture, fabricated on a 28 nm process at TSMC. It contains 2,540 million transistors on a die size of 221 mm². The RTX 5000 Mobile Ada uses the AD103 chip based on the Ada Lovelace architecture, built on a 5 nm process, also at TSMC. This chip packs 45,900 million transistors into a 379 mm² die. The transistor density tells the story: 11.5 million per mm² for Kepler versus 121.1 million per mm² for Ada Lovelace. That is a 10.5-fold increase in density, enabled by the shift from 28 nm to 5 nm.

The K2100M has 576 shading units, 48 texture mapping units, and 16 raster output units. It has no dedicated ray tracing cores and no tensor cores. The RTX 5000 Mobile Ada has 9,728 shading units, 304 TMUs, 112 ROPs, 76 ray tracing cores, and 304 tensor cores. The presence of RT and tensor cores is a fundamental architectural addition for Ada Lovelace, enabling hardware-accelerated ray tracing and AI-driven features that Kepler cannot perform at all. The K2100M’s compute rates are 768.4 GFLOPS for FP32, with no FP16 capability listed. The RTX 5000 achieves 41.15 TFLOPS for FP32 and the same 41.15 TFLOPS for FP16 with a 1:1 ratio. That is a roughly 53.5 times increase in FP32 throughput.

Pixel and texture rates also differ dramatically. The K2100M delivers 8.004 GPixel/s and 32.02 GTexel/s. The RTX 5000 Mobile Ada delivers 236.9 GPixel/s and 643.0 GTexel/s. The RTX 5000 is about 29.6 times faster in pixel rate and 20.1 times faster in texture rate. The architectural changes also affect the memory subsystem. The K2100M uses a 128-bit GDDR5 interface with 48.13 GB/s bandwidth, while the RTX 5000 uses a 256-bit GDDR6 interface with 576.0 GB/s bandwidth. The latter is 12 times higher bandwidth, which is critical for the larger compute and rendering workloads the Ada part is designed to handle.

Specification Differences

The two GPUs differ in nearly every measurable specification. The process node moves from 28 nm to 5 nm. Transistor count rises from 2,540 million to 45,900 million. Die size increases from 221 mm² to 379 mm². The K2100M’s base and boost clocks are both 667 MHz, while the RTX 5000 Mobile Ada has a base clock of 1425 MHz and a boost clock of 2115 MHz. Memory clock also jumps from 752 MHz (3 Gbps effective) to 2250 MHz (18 Gbps effective).

Memory capacity goes from 2 GB GDDR5 to 16 GB GDDR6. Bus width doubles from 128 bit to 256 bit. Bandwidth increases from 48.13 GB/s to 576.0 GB/s. Shading units rise from 576 to 9,728, TMUs from 48 to 304, and ROPs from 16 to 112. The RTX 5000 adds 76 ray tracing cores and 304 tensor cores, which the K2100M lacks entirely. Pixel rate goes from 8.004 GPixel/s to 236.9 GPixel/s. Texture rate goes from 32.02 GTexel/s to 643.0 GTexel/s. FP32 performance goes from 768.4 GFLOPS to 41.15 TFLOPS. FP16 is absent on the K2100M but listed as 41.15 TFLOPS on the RTX 5000.

TDP differs from 55 W for the K2100M to 120 W for the RTX 5000. The slot width changes from MXM Module to IGP. The bus interface moves from MXM-A (3.0) to PCIe 4.0 x16. Both use no power connectors and both have display outputs described as portable device dependent. DirectX support goes from 12 (11_0) to 12 Ultimate (12_2). Vulkan support goes from 1.2.175 to 1.4. OpenGL stays at 4.6 for both. Production status changes from end-of-life to active. Release dates are July 2013 for the K2100M and March 2023 for the RTX 5000. The predecessor and successor fields also differ: the K2100M follows Quadro Fermi-M and precedes Quadro Maxwell-M, while the RTX 5000 follows Ampere-MW and precedes Blackwell-MW.

Where Each One Wins

The Quadro K2100M wins in the context of its own benchmark set. Its average score of 4151 places it above several rivals, including the AMD Radeon RX 9060 XT 8 GB and the Intel HD Graphics 630. For workloads represented by Geekbench Metal, OpenCL, and Vulkan, the K2100M shows consistent compute performance in the 3500 to 4600 range. It also has a much lower TDP at 55 W compared to 120 W, which makes it a lighter power draw for older mobile systems. The K2100M’s smaller die size and fewer transistors also suggest lower manufacturing complexity for its era, though this is not a user-facing advantage.

The RTX 5000 Mobile Ada Generation wins on every architectural and specification front. It has 16.9 times more shading units, 6.3 times more TMUs, 7 times more ROPs, and 12 times more memory bandwidth. It supports hardware ray tracing and tensor operations, which the K2100M cannot do. Its FP32 throughput is 53.5 times higher, and it adds FP16 support at the same rate, which is essential for modern AI and machine learning workloads. The 76 ray tracing cores and 304 tensor cores open up features like DLSS and real-time ray-traced rendering, none of which are possible on Kepler. The RTX 5000 also supports DirectX 12 Ultimate, a significant upgrade over the K2100M’s DirectX 12 (11_0), and a newer Vulkan version at 1.4.

For use cases, the K2100M is suited for legacy workstation tasks that rely on older compute APIs like OpenCL and Metal, where its scores remain competitive with entry-level GPUs from its time. Its 2 GB GDDR5 memory and 128-bit bus are enough for basic CAD or visualization tasks from the mid-2010s. The RTX 5000 Mobile Ada is the clear choice for modern workloads: large 3D scenes, AI inference, machine learning training, real-time ray tracing, and high-resolution video processing. Its 16 GB GDDR6 memory and 576 GB/s bandwidth handle large datasets that would overwhelm the K2100M. The 120 W TDP, while higher, is typical for a high-end mobile workstation part.

The data does not support a single winner across all scenarios because the benchmark sets do not overlap. The K2100M’s win is relative to its own peers, not against the RTX 5000. The RTX 5000’s win is absolute in terms of specifications and feature support. For any modern software that can utilize DirectX 12 Ultimate, ray tracing, or tensor cores, the RTX 5000 Mobile Ada is the only viable option. For legacy applications that only use OpenGL 4.6 or older compute APIs, the K2100M may still function, but its performance ceiling is far lower. The recorded data shows the RTX 5000’s single 3DMark score of 3596 is modest, but that result does not reflect its architectural capabilities in compute-heavy or ray-traced workloads. The K2100M’s higher average score is a product of different, less demanding tests.
