NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 3080 Ti Mobile Comparison

The NVIDIA GeForce RTX 3080 Ti Mobile and the NVIDIA GeForce GTX 1630 are both end-of-life graphics solutions from NVIDIA, but they occupy entirely different performance strata. The RTX 3080 Ti Mobile is a high-end Ampere laptop part, while the GTX 1630 is a low-end Turing desktop card. Benchmark data shows the mobile RTX 3080 Ti leads by a massive margin in every shared test, making the comparison less about competition and more about illustrating the generational and market-segment gap between the two.

The Verdict

Based strictly on the benchmark data, the NVIDIA GeForce RTX 3080 Ti Mobile is the definitive choice for any user requiring high-performance graphics. Its average benchmark score of 25740 places it in the 71st percentile of all GPUs, while the GTX 1630’s average score of 24277 places it in the 70th percentile. Despite the similar percentile ranking, the raw performance gap is enormous. In the Geekbench OpenCL test, the RTX 3080 Ti Mobile scores 117866, which is 374.2% higher than the GTX 1630’s 24858. Similarly, in the Geekbench Vulkan test, the RTX 3080 Ti Mobile scores 107502, a 353.7% advantage over the GTX 1630’s 23695.

The RTX 3080 Ti Mobile wins both head-to-head benchmarks, solidifying its position as the superior product. The GTX 1630, with its 4 GB memory and 64-bit bus, is simply not in the same league. For a user with a portable device, the RTX 3080 Ti Mobile offers a level of compute and graphics capability that the GTX 1630 cannot approach. The GTX 1630, on the other hand, is a desktop card with a 75 W TDP and single-slot design, suited for basic tasks but not for demanding applications. The data is unequivocal: the RTX 3080 Ti Mobile is for users who need high-end performance, while the GTX 1630 is for those with minimal requirements.

Architecture Differences

The RTX 3080 Ti Mobile is built on the Ampere architecture using the GA103 chip, manufactured on an 8 nm process by Samsung. This chip contains 22,000 million transistors on a 496 mm² die, yielding a transistor density of 44.4M per mm². The architecture supports DirectX 12 Ultimate (12_2) and includes dedicated hardware for ray tracing and AI acceleration, with 58 RT cores and 232 tensor cores. The GTX 1630, in contrast, uses the Turing architecture with the TU117 chip, manufactured on a 12 nm process by TSMC. It has 4,700 million transistors on a 200 mm² die, with a transistor density of 23.5M per mm². The GTX 1630 lacks RT and tensor cores entirely, and its DirectX support is limited to 12 (12_1), not the Ultimate tier.

The RTX 3080 Ti Mobile’s Ampere architecture also allows for FP32 and FP16 compute at a 1:1 ratio, both rated at 18.71 TFLOPS. The GTX 1630’s Turing architecture provides FP32 at 1.828 TFLOPS and FP16 at 3.656 TFLOPS with a 2:1 ratio. The presence of tensor cores in the RTX 3080 Ti Mobile enables features that are absent on the GTX 1630, such as DLSS. Furthermore, the RTX 3080 Ti Mobile has a significantly more robust feature set for modern workloads, as indicated by its higher compute rates and support for the latest API standards.

Specification Differences

The two GPUs differ substantially across nearly every specification field. The RTX 3080 Ti Mobile has 7424 shading units, 232 TMUs, and 96 ROPs, while the GTX 1630 has 512 shading units, 32 TMUs, and 16 ROPs. This core configuration leads to a pixel rate of 121.0 GPixel/s and a texture rate of 292.3 GTexel/s for the RTX 3080 Ti Mobile, versus 28.56 GPixel/s and 57.12 GTexel/s for the GTX 1630. The memory subsystem is also vastly different: the RTX 3080 Ti Mobile uses 16 GB of GDDR6 on a 256-bit bus for 512.0 GB/s bandwidth, while the GTX 1630 uses 4 GB of GDDR6 on a 64-bit bus for 96.00 GB/s.

Clock speeds present an interesting contrast. The GTX 1630 has a higher base clock of 1740 MHz and boost clock of 1785 MHz, while the RTX 3080 Ti Mobile has a lower base clock of 810 MHz and boost clock of 1260 MHz. Despite the lower clocks, the RTX 3080 Ti Mobile’s massive core count delivers far higher throughput. The memory clock also differs, with the RTX 3080 Ti Mobile running at 2000 MHz (16 Gbps effective) versus the GTX 1630’s 1500 MHz (12 Gbps effective). The bus interfaces are different as well: the RTX 3080 Ti Mobile uses PCIe 4.0 x16, while the GTX 1630 uses PCIe 3.0 x16. The GTX 1630 is a single-slot card with dimensions of 145 mm in length, 69 mm in height, and 18 mm in width, and its display outputs include 1x DVI, 1x HDMI 2.0, and 1x DisplayPort 1.4a. The RTX 3080 Ti Mobile’s display outputs are listed as portable device dependent.

Head-to-Head Benchmarks

The head-to-head benchmark data shows a complete sweep for the RTX 3080 Ti Mobile, with two wins and zero for the GTX 1630. The largest margin is in the Geekbench OpenCL test, where the RTX 3080 Ti Mobile scores 117866 against the GTX 1630’s 24858. This represents a 374.2% delta, meaning the RTX 3080 Ti Mobile delivers nearly 4.7 times the compute performance in this workload. This test highlights the raw compute advantage of the RTX 3080 Ti Mobile, driven by its 7424 shading units and 18.71 TFLOPS FP32 throughput, compared to the GTX 1630’s 512 shading units and 1.828 TFLOPS.

In the Geekbench Vulkan test, the RTX 3080 Ti Mobile again dominates, scoring 107502 versus the GTX 1630’s 23695. The 353.7% delta in this test underscores the RTX 3080 Ti Mobile’s superior graphics and compute capabilities under a modern graphics API. While the GTX 1630 has a higher boost clock, it cannot compensate for the sheer difference in execution resources. The benchmark results are consistent with the specification differences: the RTX 3080 Ti Mobile’s 58 RT cores and 232 tensor cores provide additional processing power that the GTX 1630 lacks entirely. Across both tests, the data shows an overwhelming performance advantage for the RTX 3080 Ti Mobile, confirming its position as a high-end part, while the GTX 1630 remains a low-end solution.
