NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

The GeForce GTX 1630 and the GeForce RTX 3070 Ti Mobile occupy opposite ends of NVIDIA’s recent desktop and laptop lineups. The data shows a decisive performance gap, but the comparison is more nuanced than a simple scoreboard, revealing fundamental architectural and market positioning differences. This analysis examines the benchmark results, architecture, and use cases to determine which GPU serves which purpose.

Head-to-Head Benchmarks

The head-to-head data is stark, with the RTX 3070 Ti Mobile winning both shared tests by a massive margin. In the Geekbench OpenCL test, the RTX 3070 Ti Mobile scores 106,022 against the GTX 1630’s 24,858. That is a delta of -76.6% from the perspective of the GTX 1630, meaning the mobile Ampere part delivers over four times the compute throughput in this workload. The Vulkan test tells a similar story: the RTX 3070 Ti Mobile posts 100,027 versus the GTX 1630’s 23,695, a -76.3% delta. These are not incremental improvements; they represent a generational chasm in raw compute capability.

Looking at the broader benchmark context, the GTX 1630’s average benchmark score is 24,277, placing it at the 70th percentile of all GPUs. Its nearest rivals include the GeForce GTX 780 Ti (avg 24,236, delta 0.2%) and the RTX 2080 SUPER (avg 24,170, delta 0.4%), indicating it sits in a performance tier comparable to much older high-end parts. The RTX 3070 Ti Mobile, however, averages 23,518 across all its benchmarks, which is actually lower than the GTX 1630’s average due to the inclusion of lightweight Passmark DX9/DX10 tests that drag down its mean. Its percentile is 69th, just one point below the desktop card, yet its flagship test—3DMark Steel Nomad DX12—scores 2,572, and its Passmark G3D score is 17,727, showing strength in modern, heavy workloads. The delta between the two in the shared OpenCL test is the clearest indicator: the RTX 3070 Ti Mobile is in a different league for compute-intensive tasks.

Architecture Differences

The architectural divide is immense. The GTX 1630 uses the TU117 chip built on TSMC’s 12 nm process, while the RTX 3070 Ti Mobile uses the GA104 chip on Samsung’s 8 nm node. Transistor counts reflect this: the GA104 packs 17,400 million transistors versus 4,700 million on the TU117, with the die size growing from 200 mm² to 392 mm². Transistor density nearly doubles from 23.5M per mm² to 44.4M per mm², showing a much more tightly packed design.

The core configurations are wildly different. The GTX 1630 has 512 shading units, 32 texture mapping units, and 16 ROPs. The RTX 3070 Ti Mobile has 5,888 shading units, 184 TMUs, and 96 ROPs—more than an order of magnitude more shading hardware. Critically, the RTX 3070 Ti Mobile includes 46 ray tracing cores and 184 tensor cores, features entirely absent from the GTX 1630. This enables DirectX 12 Ultimate (12_2) on the mobile part, versus the GTX 1630’s DirectX 12 (12_1). The FP32 throughput tells the tale: 16.60 TFLOPS for the RTX 3070 Ti Mobile versus 1.828 TFLOPS for the GTX 1630, a 9x difference. FP16 performance is also revealing: the RTX 3070 Ti Mobile achieves 16.60 TFLOPS at a 1:1 ratio, while the GTX 1630 hits 3.656 TFLOPS only via a 2:1 rate, indicating the newer architecture handles half-precision natively.

Memory systems further separate them. The GTX 1630 has 4 GB of GDDR6 on a 64-bit bus, yielding 96.00 GB/s bandwidth. The RTX 3070 Ti Mobile doubles capacity to 8 GB, quadruples the bus to 256-bit, and achieves 448.0 GB/s—over 4.5 times the bandwidth. Clock speeds are counterintuitive: the GTX 1630 runs at a base of 1740 MHz and boost of 1785 MHz, while the RTX 3070 Ti Mobile idles at 915 MHz base and boosts to 1410 MHz. The mobile chip compensates with sheer core count, not clock speed. The power envelope also differs, with the GTX 1630 rated at 75 W TDP versus 115 W for the mobile part, though the latter has no suggested PSU figure, being portable-device dependent.

Where Each One Wins

Based strictly on the data, the RTX 3070 Ti Mobile wins every shared benchmark and every architectural category that matters for modern gaming and compute. It is the clear choice for any workload involving ray tracing, tensor operations, or high-resolution textures, given its 8 GB frame buffer and 448 GB/s bandwidth. The 3DMark Steel Nomad DX12 score of 2,572, alongside Passmark DX11 and DX12 scores of 153 and 73 (relative to its own DX9 score of 196), suggests it scales well with modern APIs. The GTX 1630 has no such results, indicating it is not positioned for current-generation titles.

However, the GTX 1630 has its own niche. Its 75 W TDP and lack of power connectors make it a drop-in upgrade for legacy systems with limited power supplies. Its 145 mm length and single-slot profile fit in compact cases. Its average benchmark score of 24,277 is actually higher than the RTX 3070 Ti Mobile’s 23,518 average, which is skewed by low-end Passmark tests. In pure OpenCL and Vulkan, the GTX 1630 is dramatically slower, but for older DirectX 9/10 titles, the RTX 3070 Ti Mobile’s Passmark scores (196 for DX9, 124 for DX10) suggest it still handles them, just not as efficiently relative to its peak. The GTX 1630’s 70th percentile versus the RTX 3070 Ti Mobile’s 69th percentile shows that in aggregate legacy benchmarks, the desktop card holds its own, but this is a statistical artifact of test selection, not real-world parity.

The Verdict

The data is unambiguous: the RTX 3070 Ti Mobile is the superior GPU for any task requiring modern features or high compute throughput. It wins both head-to-head tests by over 76%, has 46 RT cores and 184 tensor cores, and offers 8 GB of VRAM with 448 GB/s bandwidth. Gamers playing DirectX 12 Ultimate titles or creators using GPU compute will see massive gains. The GTX 1630, despite its lower average score being misleadingly close, is a legacy part. Its 512 shading units and 1.828 TFLOPS cannot compete with the mobile Ampere’s 5,888 units and 16.60 TFLOPS. For anyone building a new system or upgrading for modern games, the RTX 3070 Ti Mobile is the only rational choice, provided it fits in a laptop chassis. For a budget desktop where power draw is paramount and the user plays only older or esports titles, the GTX 1630’s 75 W TDP and single-slot design are significant advantages—but the performance ceiling is low. The verdict from the data: pick the RTX 3070 Ti Mobile for performance, pick the GTX 1630 only for minimal power and space constraints.
