NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 4070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap between the NVIDIA GeForce RTX 4070 Mobile and the NVIDIA GeForce GTX 1630. In the two benchmark tests where both cards have recorded scores, the RTX 4070 Mobile wins both decisively.

In Geekbench OpenCL, the RTX 4070 Mobile scores 109,197, while the GTX 1630 scores 24,858. That is a 339.3% advantage for the mobile Ada Lovelace part. The Geekbench Vulkan result is even more lopsided: the RTX 4070 Mobile posts 108,367 against the GTX 1630's 23,695, a 357.3% delta. These are not marginal wins; the RTX 4070 Mobile more than quadruples the GTX 1630's output in Vulkan compute workloads.

The RTX 4070 Mobile's average benchmark score across all recorded tests is 27,435. The GTX 1630 averages 24,277. While the head-to-head deltas are enormous, the average score gap is smaller because the database includes a broader set of workloads for the RTX 4070 Mobile, including Passmark tests where its scores vary by API generation. For instance, the RTX 4070 Mobile scores 223 in Passmark DirectX 9, 179 in DirectX 11, 116 in DirectX 10, and 85 in DirectX 12. It also records 19,587 in Passmark G3D, 8,399 in GPU Compute, and 763 in G2D. The GTX 1630 has no recorded Passmark scores in this database, so direct comparisons across those tests are not possible.

Percentile rankings place both cards in similar territory overall: the RTX 4070 Mobile sits at the 73rd percentile of all GPUs, while the GTX 1630 sits at the 70th percentile. This is a useful context check. The RTX 4070 Mobile's nearest rivals by average score include the AMD Radeon RX 6700 XT (27,425, a 0% delta), the NVIDIA GeForce RTX 3090 (27,565, 0.5% higher), the NVIDIA RTX PRO 4000 Blackwell (27,135, 1.1% lower), and the AMD Radeon Pro Vega 20 (27,839, 1.5% higher). So the RTX 4070 Mobile is effectively trading blows with desktop-class flagship cards from previous generations, despite being a mobile part.

The GTX 1630's nearest rivals tell a different story. It lands near the NVIDIA GeForce GTX 780 Ti (24,236, 0.2% lower), the NVIDIA GeForce RTX 2080 SUPER (24,170, 0.4% lower), the AMD Radeon RX 6600 XT (24,442, 0.7% higher), and the AMD Radeon RX 6800S (24,063, 0.9% lower). The GTX 1630 is therefore competitive with much higher-tier cards from older generations, but those rivals are all still far behind the RTX 4070 Mobile in absolute terms.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4070 Mobile is the faster GPU by a wide margin in every shared benchmark. The 339.3% OpenCL lead and 357.3% Vulkan lead are the only direct comparisons available, and both point the same way. Anyone choosing between these two purely on performance should select the RTX 4070 Mobile without hesitation.

The GTX 1630 is not without merit, however. It is a 75 W single-slot card with no power connectors, a 145 mm length, and a suggested PSU of 250 W. The RTX 4070 Mobile, by contrast, is rated at 115 W and is an IGP form factor with no power connectors, designed for portable devices. The GTX 1630 is an end-of-life product, while the RTX 4070 Mobile is active in production. The GTX 1630 is also a desktop card with fixed display outputs (1x DVI, 1x HDMI 2.0, 1x DisplayPort 1.4a), while the RTX 4070 Mobile's outputs are portable device dependent.

The verdict from the database: the RTX 4070 Mobile is the clear choice for performance. The GTX 1630 is the choice only when a low-power, single-slot, physically compact desktop card is required and the workload is light. There is no benchmark category in the shared data where the GTX 1630 wins.

Where Each One Wins

The RTX 4070 Mobile wins every single benchmark where both cards have recorded scores. In OpenCL compute, it is 339.3% ahead. In Vulkan compute, it is 357.3% ahead. Those are the only two head-to-head tests available, so the win record is 2 for the RTX 4070 Mobile and 0 for the GTX 1630.

The RTX 4070 Mobile also brings features the GTX 1630 lacks entirely. It has 36 ray tracing cores and 144 tensor cores. The GTX 1630 has neither. The RTX 4070 Mobile supports DirectX 12 Ultimate (12_2), while the GTX 1630 is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so API compatibility is equal in those areas.

The GTX 1630's only advantages are physical and power related. It draws 75 W versus 115 W, it is a single-slot card rather than an IGP, and it has a 145 mm length, 69 mm height, and 18 mm width. It also has a higher base clock (1740 MHz versus 1395 MHz) and a higher boost clock (1785 MHz versus 1695 MHz), though those clocks do not translate into performance wins. The GTX 1630's smaller memory footprint (4 GB versus 8 GB) and narrower 64-bit bus versus 128-bit are clear disadvantages.

The use-case split is simple. The RTX 4070 Mobile is for anyone who needs compute throughput, ray tracing, tensor acceleration, or modern DirectX 12 Ultimate features. The GTX 1630 is for anyone who needs a low-power, single-slot desktop card with minimal physical footprint and no external power requirement.

Architecture Differences

The two GPUs come from different generations and architectures. The RTX 4070 Mobile uses the AD106 chip based on Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It integrates 22,900 million transistors on a 188 mm² die, giving a transistor density of 121.8 million transistors per mm². The GTX 1630 uses the TU117 chip based on Turing architecture, also fabricated at TSMC but on a 12 nm process. It has 4,700 million transistors on a 200 mm² die, a density of 23.5 million transistors per mm². The RTX 4070 Mobile is therefore denser in a smaller package.

The RTX 4070 Mobile belongs to the GeForce 40 Mobile generation and is the successor to GeForce 30 Mobile. The GTX 1630 belongs to the GeForce 16 generation and is the successor to GeForce 10. The RTX 4070 Mobile's successor is GeForce 50 Mobile, while the GTX 1630's successor is GeForce 20.

Compute resources differ sharply. The RTX 4070 Mobile has 4,608 shading units, 144 texture mapping units, and 48 raster output pipelines. The GTX 1630 has 512 shading units, 32 TMUs, and 16 ROPs. The RTX 4070 Mobile also has 36 ray tracing cores and 144 tensor cores, which the GTX 1630 lacks entirely. The RTX 4070 Mobile's FP32 throughput is 15.62 TFLOPS with a 1:1 FP16 ratio, while the GTX 1630 manages 1.828 TFLOPS FP32 and 3.656 TFLOPS FP16 with a 2:1 ratio.

Memory architecture also differs. The RTX 4070 Mobile uses 8 GB of GDDR6 at 2000 MHz (16 Gbps effective) on a 128-bit bus, yielding 256.0 GB/s bandwidth. The GTX 1630 uses 4 GB of GDDR6 at 1500 MHz (12 Gbps effective) on a 64-bit bus, yielding 96.00 GB/s. Pixel rates are 81.36 GPixel/s for the RTX 4070 Mobile versus 28.56 GPixel/s for the GTX 1630. Texture rates are 244.1 GTexel/s versus 57.12 GTexel/s.

The bus interface differs: the RTX 4070 Mobile uses PCIe 4.0 x8, while the GTX 1630 uses PCIe 3.0 x16. The RTX 4070 Mobile is an IGP with no slot width and no power connectors, and its display outputs are portable device dependent. The GTX 1630 is a single-slot card with 1x DVI, 1x HDMI 2.0, and 1x DisplayPort 1.4a outputs, measuring 145 mm by 69 mm by 18 mm.

API support is another differentiator. The RTX 4070 Mobile supports DirectX 12 Ultimate (12_2), while the GTX 1630 supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX 4070 Mobile was released on January 2, 2023, and is still in active production. The GTX 1630 was released on June 27, 2022, and is now end-of-life.
