NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 3070 Mobile Comparison

# NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 3070 Mobile

The comparison between these two NVIDIA parts is a study in generational contrast. The GeForce GTX 1630 (16-series Turing, 2022, end-of-life) and the GeForce RTX 3070 Mobile (30-series Ampere, 2021, end-of-life) represent two very different tiers. The recorded data places them 65 to 70 percentiles apart when ranked against all other GPUs, which is a significant gap for those weighing a modern mobile part against an entry-level desktop offering.

The database records a head-to-head benchmark suite with two clear results. The RTX 3070 Mobile wins both recorded tests outright, making it the decisive pick according to raw performance. The GTX 1630 trails in each case, but the margins are enormous and consistent with the architecture gap.

Head-to-Head Benchmarks

The benchmark data shows two recorded head-to-head tests: Geekbench OpenCL and Geekbench Vulkan. These are the only direct measurements in the database, and they establish who leads in compute workloads.

Geekbench OpenCL: The GeForce RTX 3070 Mobile scores 92,939, while the GTX 1630 scores 24,858. This is a 73.3% advantage for the RTX 3070 Mobile. The result places the RTX 3070 Mobile in a different performance class entirely, with the GTX 1630 delivering roughly a quarter of the compute throughput.

Geekbench Vulkan: The RTX 3070 Mobile posts 86,768, against the GTX 1630's 23,695. The margin is 72.7% in favor of the RTX 3070 Mobile. The Vulkan results are lower than OpenCL for both parts, a pattern that often indicates driver overhead differences, but the huge gap remains in both test families.

The head-to-head record is 2:0 for the RTX 3070 Mobile. The GTX 1630 is not competitive in these compute-oriented loads, and the data does not show any test where the older card takes a win.

Where Each One Wins

The benchmark results indicate a strict performance separation.

Compute-heavy synthetic workloads (OpenCL, Vulkan): The RTX 3070 Mobile dominates both recorded tests. Its 160 tensor cores and 40 RT cores are designed to accelerate such workloads, and the 448.0 GB/s memory bandwidth gives it headroom. The GTX 1630 with 32 tensor cores and 16 RT cores cannot keep up, and its 12 Gbps effective memory bandwidth is much lower.

Legacy desktop use cases: The GTX 1630 may still hold appeal where the unique factor is a low-profile, single-slot card with no auxiliary power connectors. The measurement data shows its transistor density of 23.5M/mm² (4,700 million transistors on 200 mm²) is high, but it is an end-of-life product.

Modern mobile gaming and creation: The data clearly suggests the RTX 3070 Mobile is the one to choose for anything beyond the most basic 3D tasks. Its 15.97 TFLOPS FP32 rating versus 1.828 TFLOPS for the GTX 1630 is a 8.7x difference.

Architecture Differences

The two chips come from separate foundries and architectures, which explains the performance chasm.

| Transistor density | 23.5M / mm² | 44.4M / mm² |

| Tensor cores | None | 160 |

| RT cores | None | 40 |

| CUDA cores | 512 | 5,120 |

The GTX 1630 lacks dedicated tensor and RT cores, while the RTX 3070 Mobile has 160 tensor cores and 40 RT cores. The RTX part also has 80 ROPs and 160 texture mapping units versus 16 and 32 for the GTX. The shading unit count, 5,120 vs 512, is a 10x difference.

Memory subsystems are also far apart. The RTX 3070 Mobile uses 8 GB of GDDR6 on a 256-bit bus for 448.0 GB/s. The GTX 1630 uses 4 GB GDDR6 on a 64-bit bus at 96 GB/s.

The RTX 3070 Mobile has a 14 Gbps effective memory speed, versus 12 Gbps effective for the GTX 1630. The GTX's memory clock is 1500 MHz, the RTX runs 1750 MHz.

The RTX card has no fixed width, but the GTX is a single-slot card. The power connector lists "None" for both. The GTX suggests a 250 W PSU, while the RTX is a 115 W TDP part, which is likely to be more at home in a laptop.

The Verdict

The data is one-sided. The RTX 3070 Mobile is the definitive choice for anyone running compute-oriented tasks (OpenCL, Vulkan).

The GTX 1630 is a product of the Turing generation without the dedicated tensor/RT hardware. Its transistor density is 23.5M/mm² (vs. 44.4M for the RTX). The RTX 3070 Mobile is a much larger die: 392 mm² vs 200 mm², and has 3.7x the transistors.

For those who need raw compute on a laptop, the RTX 3070 Mobile is the only logical pick. It also has 2x the memory capacity (8 GB vs 4 GB) and 4.7x the bandwidth. If the load is a legacy or low-power, the GTX 1630 may still have a place as a single-slot, end-of-life card with no external power, but in the face of the data, the RTX 3070 Mobile is the stronger part. The database shows 2 head-to-head wins for the RTX, 0 for the GTX.

The GTX 1630's launch status is End-of-life, it's a 2022 release. The RTX 3070 Mobile is also End-of-life, released in 2021. Both are older parts, but the RTX part remains in a different league.
