NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 4060 Mobile Comparison

The data presents a stark generational contrast between two NVIDIA GPUs: the desktop-oriented GeForce GTX 1630 and the mobile GeForce RTX 4060 Mobile. The GTX 1630 is an end-of-life entry-level part from the GeForce 16 generation, while the RTX 4060 Mobile is an active, high-end laptop chip from the GeForce 40 series. The benchmark results overwhelmingly favor the newer mobile part, but the comparison reveals more than just a raw performance gap; it highlights fundamental architectural and specification shifts.

The Verdict

Based strictly on the benchmark data, the NVIDIA GeForce RTX 4060 Mobile is the definitive performance winner. In Geekbench OpenCL, it scores 89,420 against the GTX 1630’s 24,858, representing a 72.2% advantage. In Geekbench Vulkan, the margin is similar, with the RTX 4060 Mobile scoring 89,569 versus 23,695, a 73.5% lead. These are not incremental gains; they are transformative leaps that place the two products in entirely different performance tiers.

The GTX 1630, despite its lower raw scores, holds a 70th percentile ranking among all GPUs, which is actually higher than the RTX 4060 Mobile’s 67th percentile. This discrepancy is likely due to the fact that the GTX 1630’s average benchmark score of 24,277 is clustered closely with its nearest rivals, including the GeForce GTX 780 Ti (0.2% ahead) and the Radeon RX 6600 XT (0.7% behind). In contrast, the RTX 4060 Mobile’s average score of 22,729 is pulled down by its Passmark DirectX tests, which are low (e.g., 73 for DirectX 12) but its OpenCL and Vulkan scores are exceptionally high.

The choice is clear for performance-seeking users: the RTX 4060 Mobile is the only option with meaningful compute power. The GTX 1630 is a legacy part that, while competitive within its own narrow desktop niche, cannot compete with the mobile chip’s modern architecture. The data suggests the GTX 1630 is for basic display output or legacy system builds, while the RTX 4060 Mobile is for demanding applications like modern gaming or content creation, provided the user is on a laptop platform.

FAQ

Q: Which GPU has the higher average benchmark score?

A: The NVIDIA GeForce GTX 1630 has a higher average benchmark score of 24,277 compared to the RTX 4060 Mobile’s 22,729. This is misleading, however, as the RTX 4060 Mobile’s average is dragged down by its low Passmark scores, while its Geekbench scores are far superior.

Q: How much faster is the RTX 4060 Mobile in OpenCL?

A: The RTX 4060 Mobile is 72.2% faster in Geekbench OpenCL, scoring 89,420 versus the GTX 1630’s 24,858.

Q: What is the memory configuration difference?

A: The GTX 1630 has 4 GB of GDDR6 on a 64-bit bus with 96.00 GB/s bandwidth. The RTX 4060 Mobile has 8 GB of GDDR6 on a 128-bit bus, doubling bandwidth to 256.0 GB/s.

Q: Which GPU has a higher pixel fill rate?

A: The RTX 4060 Mobile has a significantly higher pixel rate of 90.72 GPixel/s, compared to the GTX 1630’s 28.56 GPixel/s.

Q: Do both GPUs support the same DirectX version?

A: No. The GTX 1630 supports DirectX 12 (12_1), while the RTX 4060 Mobile supports DirectX 12 Ultimate (12_2).

Q: Which GPU is smaller in terms of die size?

A: The RTX 4060 Mobile has a smaller die size of 159 mm², despite having far more transistors (18,900 million) than the GTX 1630’s 200 mm² die with 4,700 million transistors.

Architecture Differences

The architectural gap between these two GPUs is immense, explaining the performance disparity. The GTX 1630 is based on the Turing architecture, built on a 12 nm process at TSMC. It uses the TU117 chip, which is a small, entry-level design. It has no dedicated ray tracing or tensor cores, meaning it lacks hardware acceleration for these modern workloads. Its transistor density is 23.5M / mm², reflecting an older, less efficient design.

In contrast, the RTX 4060 Mobile uses the Ada Lovelace architecture, built on a much more advanced 5 nm process, also at TSMC. Its AD107 chip packs 18,900 million transistors into a smaller 159 mm² die, achieving a transistor density of 118.9M / mm². This is a massive efficiency leap. Crucially, it includes 24 dedicated ray tracing cores and 96 tensor cores, enabling hardware-accelerated ray tracing and AI features that the GTX 1630 simply cannot perform. The FP16 performance also differs: the GTX 1630 offers 3.656 TFLOPS (2:1 ratio), while the RTX 4060 Mobile offers 11.61 TFLOPS (1:1 ratio), indicating full-rate half-precision compute on the newer part.

Specification Differences

The specification sheets reveal a clear hierarchy. The RTX 4060 Mobile has 3072 shading units, 96 TMUs, and 48 ROPs, dwarfing the GTX 1630’s 512 shading units, 32 TMUs, and 16 ROPs. The memory subsystem is also doubled in capacity and width: 8 GB on a 128-bit bus versus 4 GB on a 64-bit bus. The effective memory speed is higher on the RTX 4060 Mobile at 16 Gbps, compared to 12 Gbps on the GTX 1630.

Clock speeds are interesting; the GTX 1630 has a higher base clock of 1740 MHz versus 1545 MHz, but the RTX 4060 Mobile has a higher boost clock of 1890 MHz versus 1785 MHz. The RTX 4060 Mobile has a much higher TDP of 115 W, while the GTX 1630 is a modest 75 W part. The GTX 1630 is a single-slot desktop card with specific display outputs (1x DVI, 1x HDMI 2.0, 1x DisplayPort 1.4a), while the RTX 4060 Mobile is an IGP (Integrated Graphics Processor) for laptops, with portable-device-dependent outputs. The RTX 4060 Mobile also uses a newer PCIe 4.0 x8 interface, compared to the GTX 1630’s PCIe 3.0 x16. The GTX 1630 has a suggested PSU of 250 W, while the RTX 4060 Mobile has no such requirement as it is not a discrete desktop card.

Head-to-Head Benchmarks

The only comparable benchmarks are the two Geekbench tests, and the RTX 4060 Mobile dominates both. In Geekbench OpenCL, the RTX 4060 Mobile scores 89,420, a 72.2% improvement over the GTX 1630’s 24,858. This indicates a massive advantage in general-purpose compute, likely stemming from the 6x increase in shading units and the newer architecture.

In Geekbench Vulkan, the result is even more lopsided. The RTX 4060 Mobile scores 89,569, while the GTX 1630 manages only 23,695. The delta is 73.5% in favor of the RTX 4060 Mobile. This suggests that the newer architecture is particularly efficient in low-level graphics APIs. The RTX 4060 Mobile also has a Passmark G3D score of 17,469, though the GTX 1630 does not have a comparable score in this dataset. The GTX 1630’s scores are competitive with its nearest rivals (GTX 780 Ti, RTX 2080 SUPER), but those rivals are all older desktop parts.

Where Each One Wins

The RTX 4060 Mobile wins in every measurable compute and graphics workload present in the data. Its advantages in shading units, memory bandwidth, and dedicated RT/tensor cores make it the clear choice for any modern, demanding application. The 256.0 GB/s bandwidth is critical for high-resolution textures and complex scenes, and the 11.61 TFLOPS FP32 performance is over six times higher than the GTX 1630’s 1.828 TFLOPS. For gaming with ray tracing or AI-accelerated features like DLSS, the RTX 4060 Mobile is the only viable option.

The GTX 1630’s only "win" is its higher percentile ranking (70th vs 67th) and its higher average benchmark score, both of which are artifacts of the RTX 4060 Mobile’s low Passmark scores. In practical terms, the GTX 1630 is suited for light, legacy workloads where its low 75 W TDP and single-slot form factor are advantages. It could serve as a basic display adapter for an older desktop system, but it cannot handle the compute or graphics load that the RTX 4060 Mobile manages with ease. The data shows the RTX 4060 Mobile is a superior product in virtually every technical aspect, and the GTX 1630 is a relic of a previous generation.
