Q: What are the architectural generations of each GPU?

A: The RTX 4070 uses the AD104 chip on the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. The Quadro K2000 uses the GK107 chip on the Kepler architecture, fabricated on a 28 nm process, also at TSMC.

Q: Do both cards support the same API feature levels?

A: The RTX 4070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Quadro K2000 supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175, so the RTX 4070 has a higher DirectX feature level and a newer Vulkan version.

Architecture Differences

The architectural gap between these two NVIDIA parts is substantial, spanning two distinct generations of GPU design. The RTX 4070 GDDR6 is built on the Ada Lovelace architecture using the AD104 chip, manufactured on a 5 nm process at TSMC. The Quadro K2000 uses the Kepler architecture with the GK107 chip, also from TSMC but on a much older 28 nm process. This process difference alone drives enormous disparities in transistor density: the RTX 4070 packs 121.8 million transistors per square millimeter, while the K2000 achieves only 10.8 million per square millimeter.

The raw transistor counts tell a similar story. The RTX 4070 integrates 35,800 million transistors on a 294 mm² die, whereas the K2000 contains just 1,270 million transistors on a 118 mm² die. That means the RTX 4070 has roughly 28 times more transistors on a die only 2.5 times larger. The RTX 4070 also features significantly more execution resources: 5888 shading units, 184 texture mapping units, and 64 raster output pipelines, compared to the K2000's 384 shading units, 32 TMUs, and 16 ROPs.

Feature support diverges sharply as well. The RTX 4070 includes 46 ray tracing cores and 184 tensor cores, while the Quadro K2000 has neither. The RTX 4070 also supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the K2000 tops out at DirectX 12 (11_0) and Vulkan 1.2.175. Both cards do share OpenGL 4.6 support, but the RTX 4070's newer architecture enables hardware-accelerated ray tracing and AI workloads that the Kepler-based K2000 cannot handle at all.

Clock behavior also differs. The RTX 4070 has a base clock of 1920 MHz and a boost clock of 2475 MHz, while the Quadro K2000 lists no base or boost clock in the data — only its memory clock of 1000 MHz (4 Gbps effective). The RTX 4070's memory runs at 2500 MHz with 20 Gbps effective speed, substantially faster than the K2000's memory clock. Power delivery and physical design also reflect the generational shift: the RTX 4070 is a dual-slot card requiring a 16-pin connector and a 550 W suggested PSU, while the K2000 is a single-slot card with no power connectors and a 250 W suggested PSU.

Head-to-Head Benchmarks

The head-to-head benchmark table between these two cards is empty, so the comparison must rely on each card's individual benchmark results and average scores. The RTX 4070 GDDR6 posts an average benchmark score of 4335, derived from its single 3DMark Steel Nomad DX12 result of 4334.5. The Quadro K2000 averages 3964 across three Geekbench tests: 3630 in Metal, 4071 in OpenCL, and 4191 in Vulkan.

The raw average gap is 371 points, which translates to roughly 9.4% in favor of the RTX 4070. Looking at the best-case scenario for the K2000, its highest score (4191 in Vulkan) still falls 143.5 points short of the RTX 4070's 4334.5 in 3DMark Steel Nomad DX12. Conversely, the K2000's lowest result (3630 in Metal) trails the RTX 4070's single score by 704.5 points.

Examining the nearest rival data provides additional context for each card's standing. The RTX 4070's rivals cluster tightly around its score: the Intel Iris Pro Graphics 5200 is 0.6% faster, the NVIDIA GeForce 930M is 1.2% faster, the AMD FirePro W2100 is 0.9% slower, and the NVIDIA GeForce GTX 460M is 1.2% slower. This tight clustering suggests the RTX 4070's benchmark position is well-bracketed in its comparison pool, with all rivals within roughly one percent.

The Quadro K2000's rivals also cluster closely but with a different spread. The AMD Radeon HD 6850 X2 leads at 0.3% faster, followed by the NVIDIA GeForce 830M at 0.2% faster and the AMD Radeon R5 M420 at 0.2% faster. The NVIDIA GeForce GT 745M trails at 0.3% slower. This indicates the K2000's average score sits in a very narrow band relative to its nearest competitors, though the absolute scores in this pool are far lower than those around the RTX 4070.

It is importantly the RTX 4070's 3DMark Steel Nomad DX12 result represents a modern DirectX 12 workload, while the K2000's Geekbench scores span Metal, OpenCL, and Vulkan — different APIs and test methodologies. The RTX 4070's percentile ranking of 25 versus the K2000's 24 shows that, despite the large absolute score difference, both cards sit near the same relative position in their respective benchmark universes.

Specification Differences

The two cards differ on nearly every specification field in the data. Starting with the chip and process, the RTX 4070 uses AD104 on a 5 nm process, while the K2000 uses GK107 on a 28 nm process. Transistor counts are 35,800 million versus 1,270 million, and die sizes are 294 mm² versus 118 mm². Transistor density is 121.8M per mm² for the RTX 4070 and 10.8M per mm² for the K2000.

Memory configurations diverge completely. The RTX 4070 has 12 GB of GDDR6 on a 192-bit bus with 480.0 GB/s bandwidth, while the K2000 has 2 GB of GDDR5 on a 128-bit bus with 64.00 GB/s bandwidth. The memory clock is 2500 MHz (20 Gbps effective) for the RTX 4070 versus 1000 MHz (4 Gbps effective) for the K2000.

Compute resources differ by an order of magnitude. The RTX 4070 has 5888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. The K2000 has 384 shading units, 32 TMUs, and 16 ROPs, with no RT or tensor cores. The RTX 4070 achieves 29.15 TFLOPS FP32 and 29.15 TFLOPS FP16 (1:1), while the K2000 delivers 732.7 GFLOPS FP32 and has no listed FP16 capability.

Pixel and texture rates follow the same pattern: the RTX 4070 produces 158.4 GPixel/s and 455.4 GTexel/s, versus 7.632 GPixel/s and 30.53 GTexel/s for the K2000. Power and physical specs also differ: the RTX 4070 is rated at 200 W TDP with a dual-slot design, 16-pin power connector, and 550 W suggested PSU, while the K2000 consumes 51 W in a single-slot design with no power connector and a 250 W suggested PSU.

The bus interface advances from PCIe 2.0 x16 on the K2000 to PCIe 4.0 x16 on the RTX 4070. Display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a on the RTX 4070, versus 1x DVI and 2x DisplayPort 1.2 on the K2000. Dimensions differ as well: the RTX 4070 measures 240 mm by 110 mm by 40 mm, while the K2000 measures 202 mm by 111 mm with no listed width. Release dates are far apart: the RTX 4070 launched on 2024-08-19, while the K2000 launched on 2013-02-28. Both are end-of-life products with identical launch MSRP of 599 USD.

Where Each One Wins

The RTX 4070 GDDR6 wins decisively in raw compute and modern workload support. Its 29.15 TFLOPS FP32 is roughly 40 times the K2000's 732.7 GFLOPS. The RTX 4070's 480.0 GB/s memory bandwidth is 7.5 times the K2000's 64.00 GB/s. For gaming and modern DirectX 12 Ultimate applications, the RTX 4070 is the clear choice, with ray tracing cores and tensor cores that enable features entirely absent on the K2000.

The RTX 4070 also wins on API support, with DirectX 12 Ultimate (12_2) versus the K2000's DirectX 12 (11_0), and Vulkan 1.4 versus 1.2.175. The RTX 4070's dual-slot design with a 16-pin connector indicates a card built for high performance, while its 200 W TDP reflects the power needed to drive 5888 shading units. The 12 GB GDDR6 frame buffer provides substantial capacity for high-resolution textures and complex scenes.

The Quadro K2000 wins in efficiency and form factor. Its 51 W TDP is less than a third of the RTX 4070's 200 W, and its single-slot design with no power connectors makes it far easier to install in compact systems. The K2000's 250 W suggested PSU requirement versus the RTX 4070's 550 W means the K2000 can run in systems with much smaller power supplies. Its 202 mm length is shorter than the RTX 4070's 240 mm, and its 111 mm height is nearly identical.

For legacy compatibility, the K2000's 1x DVI and 2x DisplayPort 1.2 outputs may suit older display setups, whereas the RTX 4070's 1x HDMI 2.1 and 3x DisplayPort 1.4a target modern monitors. The K2000's PCIe 2.0 x16 interface is backward-compatible with older motherboards, though the RTX 4070's PCIe 4.0 x16 offers far greater bandwidth. The K2000's 2 GB memory is sufficient for basic professional 2D workloads, but the RTX 4070's 12 GB is required for any substantial 3D rendering or compute task.

The Verdict

The data supports a straightforward conclusion: the GeForce RTX 4070 GDDR6 is the overwhelmingly more capable GPU in nearly every measurable dimension. Its average benchmark score of 4335 outperforms the Quadro K2000's 3964 by roughly 9.4%. The RTX 4070 offers 15 times the shading units, 480.0 GB/s versus 64.00 GB/s memory bandwidth, and 29.15 TFLOPS versus 732.7 GFLOPS FP32 compute. It also brings ray tracing, tensor cores, and DirectX 12 Ultimate support — features the K2000 simply does not have.

The Quadro K2000's only clear advantages are power consumption and physical footprint. At 51 W with a single-slot design and no power connectors, it can be dropped into systems with minimal power delivery and space constraints. Its 250 W suggested PSU requirement is less than half the RTX 4070's 550 W. For users with limited power budgets or compact chassis, the K2000 remains functional, but its 2 GB GDDR5 memory and Kepler architecture limit it to basic workloads.

Given that both cards share the same launch MSRP of 599 USD, the performance differential is stark. The RTX 4070 delivers roughly 9.4% higher average benchmark performance, but the gap in specific metrics is far larger — 40x in FP32 compute and 7.5x in memory bandwidth. The RTX 4070's 12 GB frame buffer versus 2 GB makes it suitable for modern applications, while the K2000's memory capacity is a hard constraint.

The percentile rankings (25th for RTX 4070, 24th for K2000) are close, but this reflects different comparison pools rather than similar performance. The RTX 4070's nearest rivals score around 4300-4400, while the K2000's rivals sit near 3950-3977. In absolute terms, the RTX 4070 operates in a different performance class entirely.

The choice is clear for anyone needing modern GPU features, substantial compute throughput, or large memory capacity: the RTX 4070 GDDR6 is the only viable option between these two. The Quadro K2000 remains relevant only for extremely power-constrained, low-intensity use cases where its 51 W TDP and single-slot profile are decisive. For all other scenarios, the data overwhelmingly favors the RTX 4070, making the K2000 a legacy part that has been superseded in every substantive performance category.
