NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 2080 SUPER Comparison

# NVIDIA GeForce GTX 1630 vs NVIDIA GeForce RTX 2080 SUPER

The data presents a stark contrast between two end-of-life NVIDIA offerings from the GeForce 16 and 20 series. The GTX 1630, released in June 2022, is a low-power Turing chip with 512 shading units, while the RTX 2080 SUPER, launched in July 2019, packs 3072 shading units, 48 RT cores, and 384 tensor cores. Their average benchmark scores are nearly identical—24,277 for the GTX 1630 versus 24,170 for the RTX 2080 SUPER—yet the underlying performance profiles could not be more different. The RTX 2080 SUPER dominates the two head-to-head compute tests by margins exceeding 74%, while the GTX 1630 ekes out a 0.4% lead in average score, a statistical tie that masks the older card's massive advantage in raw throughput.

The Verdict

The RTX 2080 SUPER is the clear choice for anyone prioritizing compute-heavy workloads, ray tracing, or high-resolution gaming with substantial memory requirements. Its Geekbench OpenCL score of 99,226 is roughly four times the GTX 1630's 24,858, and its Vulkan result of 111,284 nearly quintuples the GTX 1630's 23,695. The 8 GB GDDR6 memory on a 256-bit bus providing 495.9 GB/s bandwidth dwarfs the GTX 1630's 4 GB on a 64-bit bus at 96.00 GB/s. The GTX 1630, meanwhile, offers a lower-TDP alternative at 75 W versus 250 W, with no power connectors required and a single-slot design that fits in compact systems. However, its 512 shading units and 16 ROPs severely limit its ceiling. Benchmark results indicate the GTX 1630 is best suited for legacy applications, basic desktop acceleration, or systems where the 75 W power draw and 145 mm length are hard constraints. The RTX 2080 SUPER, at 267 mm and dual-slot, demands more space and a 600 W suggested PSU, but delivers DirectX 12 Ultimate support and hardware ray tracing that the GTX 1630 lacks entirely.

Architecture Differences

Both cards use the Turing architecture on TSMC's 12 nm process, but they represent opposite ends of the design spectrum. The GTX 1630 uses the TU117 chip, a small 200 mm² die with 4,700 million transistors, achieving a density of 23.5M transistors per mm². The RTX 2080 SUPER uses the TU104 chip, a massive 545 mm² die with 13,600 million transistors, reaching 25.0M per mm². The GTX 1630's memory runs at 1500 MHz with 12 Gbps effective speed, while the RTX 2080 SUPER's memory operates at 1937 MHz with 15.5 Gbps effective. The RTX 2080 SUPER's 8 GB frame buffer is double the GTX 1630's 4 GB, and its 256-bit bus delivers 495.9 GB/s versus 96.00 GB/s. The shading unit count tells the story: 3072 versus 512, with TMUs at 192 versus 32 and ROPs at 64 versus 16. The RTX 2080 SUPER adds 48 RT cores and 384 tensor cores, features absent from the GTX 1630. Pixel rate is 116.2 GPixel/s for the RTX 2080 SUPER versus 28.56 GPixel/s, and texture rate is 348.5 GTexel/s versus 57.12 GTexel/s. FP32 performance is 11.15 TFLOPS against 1.828 TFLOPS, with FP16 at 22.30 TFLOPS versus 3.656 TFLOPS. The RTX 2080 SUPER 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. Display outputs differ: the GTX 1630 offers one DVI, one HDMI 2.0, and one DisplayPort 1.4a; the RTX 2080 SUPER has one HDMI 2.0, three DisplayPort 1.4a, and one USB Type-C.

Where Each One Wins

The RTX 2080 SUPER wins decisively in every compute-oriented benchmark recorded. In Geekbench OpenCL, it scores 99,226 against the GTX 1630's 24,858, a 74.9% advantage. In Geekbench Vulkan, the margin grows to 78.7%, with scores of 111,284 versus 23,695. These results align with the massive differences in shading units, texture units, and memory bandwidth. The RTX 2080 SUPER's 8 GB memory and 256-bit bus make it suitable for modern game textures and compute workloads that exceed 4 GB. Its ray tracing and tensor cores enable features the GTX 1630 cannot access. The GTX 1630's wins are more subtle: it posts an average benchmark score of 24,277, slightly higher than the RTX 2080 SUPER's 24,170, and it holds a 0.4% edge in the nearest-rival comparison against the RTX 2080 SUPER. The GTX 1630's 75 W TDP, lack of power connectors, and single-slot profile make it far easier to integrate into small form factor builds or legacy systems with limited power delivery. Its 145 mm length versus 267 mm is a practical advantage for tight cases. For users with a 250 W suggested PSU, the GTX 1630 fits; the RTX 2080 SUPER demands 600 W. The GTX 1630 also releases later (June 2022 versus July 2019), which may imply longer driver support in the field, though both are now end-of-life.

Head-to-Head Benchmarks

The head-to-head data includes only two benchmarks, and the RTX 2080 SUPER wins both by overwhelming margins. In Geekbench OpenCL, the RTX 2080 SUPER scores 99,226 against the GTX 1630's 24,858, a delta of 74.9%. This result reflects the RTX 2080 SUPER's 3072 shading units, 192 TMUs, and 64 ROPs, which process work at rates the GTX 1630 cannot approach. The GTX 1630's 1.828 TFLOPS FP32 output is roughly one-sixth of the RTX 2080 SUPER's 11.15 TFLOPS, and the memory bandwidth gap—495.9 GB/s versus 96.00 GB/s—compounds the difference in memory-bound OpenCL workloads. The Geekbench Vulkan test shows an even larger gap: the RTX 2080 SUPER posts 111,284 versus 23,695, a 78.7% delta. Vulkan's low-level API exposes the hardware's parallel capabilities, and the RTX 2080 SUPER's 48 RT cores and 384 tensor cores, while not directly used in this compute test, indicate a far more capable execution engine. The RTX 2080 SUPER also benefits from 22.30 TFLOPS FP16 throughput, double its FP32 rate, whereas the GTX 1630's FP16 is 3.656 TFLOPS, also a 2:1 ratio but from a much lower base.

Despite these lopsided compute results, the overall average benchmark scores are nearly tied: 24,277 for the GTX 1630 and 24,170 for the RTX 2080 SUPER. This paradox likely stems from the benchmark suite's weighting—the GTX 1630's only two recorded scores are both Geekbench tests, while the RTX 2080 SUPER includes a broader set including PassMark DirectX 9, 10, 11, and 12 tests, plus G2D, G3D, and GPU Compute metrics. The RTX 2080 SUPER's PassMark G3D score is 19,490, and its GPU Compute score is 8,290, while its DirectX 9 score is 227, DirectX 10 is 140, DirectX 11 is 165, and DirectX 12 is 75. The GTX 1630 lacks these DirectX-specific results in the dataset, so its average relies entirely on the two Geekbench entries. When comparing nearest rivals, the GTX 1630 sits 0.2% above the GTX 780 Ti and 0.4% above the RTX 2080 SUPER, while the RTX 2080 SUPER sits 0.3% below the GTX 780 Ti and 0.4% below the GTX 1630. Both cards trail the AMD Radeon RX 6600 XT by 0.7% and 1.1% respectively, and both lead the AMD Radeon RX 6800S by 0.9% and 0.4%.

The practical takeaway from the head-to-head data is that the RTX 2080 SUPER is built for sustained, heavy workloads—its 13,600 million transistors and 545 mm² die provide the resources for high-end gaming and compute tasks, supported by 495.9 GB/s of bandwidth. The GTX 1630, with 4,700 million transistors on a 200 mm² die, is a modest performer whose 96.00 GB/s bandwidth and 512 shading units limit it to lighter duties. The RTX 2080 SUPER's 116.2 GPixel/s pixel rate and 348.5 GTexel/s texture rate are 4x and 6x the GTX 1630's respective figures, making it the only one of the two suitable for high-resolution, high-detail rendering. The GTX 1630's single-slot, no-connector design and 75 W TDP, however, mean it can run in systems where the RTX 2080 SUPER's 250 W TDP, dual-slot footprint, and 600 W PSU requirement simply cannot be accommodated. For users with the power budget and physical space, the RTX 2080 SUPER is the superior performer in every measured compute benchmark. For those constrained by power or chassis size, the GTX 1630 offers a functional, if limited, alternative that still places in the 70th percentile of all GPUs.
