NVIDIA GeForce GTX 1630 vs NVIDIA RTX PRO 2000 Blackwell Comparison

The benchmark data is unequivocal: the NVIDIA RTX PRO 2000 Blackwell outperforms the NVIDIA GeForce GTX 1630 by a staggering margin in every measurable test. Across the two shared benchmarks, the RTX PRO 2000 Blackwell delivers between 326.8% and 380.5% higher scores, making the GTX 1630 a non-competitive option for any modern workload. This is not a close comparison; it is a generational and architectural mismatch.

Head-to-Head Benchmarks

The only two benchmarks where both GPUs have recorded scores are Geekbench OpenCL and Geekbench Vulkan, and the results are decisive. In Geekbench OpenCL, the RTX PRO 2000 Blackwell scores 106,087 points, while the GTX 1630 manages only 24,858 points. This represents a 326.8% advantage for the RTX PRO 2000 Blackwell. In Vulkan, the gap widens further: the RTX PRO 2000 Blackwell hits 113,865 points versus 23,695 points for the GTX 1630, a 380.5% lead.

The RTX PRO 2000 Blackwell wins both head-to-head tests, giving it a 2-0 sweep. The Vulkan result is particularly telling, as the delta percentage of 380.5% is the largest of the two, suggesting the RTX PRO 2000 Blackwell’s architecture scales better with modern, low-level graphics APIs. The OpenCL gap, while slightly smaller, still represents a quadrupling of compute performance.

For context, the RTX PRO 2000 Blackwell’s average benchmark score of 25,269 places it near the AMD Radeon RX 6700M (25,633, -1.4%) and the NVIDIA GeForce RTX 3080 Ti Mobile (25,740, -1.8%). It sits 2% ahead of the NVIDIA RTX A5000 Mobile (24,763). Meanwhile, the GTX 1630’s average of 24,277 puts it in a different competitive tier entirely, trading blows with the NVIDIA GeForce GTX 780 Ti (24,236, 0.2%) and the AMD Radeon RX 6600 XT (24,442, -0.7%). The RTX PRO 2000 Blackwell’s raw score is roughly 4% higher than the GTX 1630’s average, but the per-test deltas show the true scale of the performance chasm.

Architecture Differences

The architectural divide between these two GPUs is profound. The RTX PRO 2000 Blackwell uses the GB206 chip built on TSMC’s 5 nm process, featuring 21,900 million transistors on a 181 mm² die. The GTX 1630 uses the TU117 chip on a 12 nm process, with 4,700 million transistors on a larger 200 mm² die. The transistor density tells the story: 121.0M / mm² for the RTX PRO 2000 Blackwell versus 23.5M / mm² for the GTX 1630.

The RTX PRO 2000 Blackwell is built on the Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation, and supports DirectX 12 Ultimate (12_2). The GTX 1630 is based on the older Turing architecture, from the GeForce 16 generation, and only supports DirectX 12 (12_1). The RTX PRO 2000 Blackwell also includes 34 ray tracing cores and 136 tensor cores, while the GTX 1630 has none of either.

Memory technology differs completely. The RTX PRO 2000 Blackwell uses 16 GB of GDDR7 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The GTX 1630 has 4 GB of GDDR6 on a 64-bit bus, with just 96.00 GB/s of bandwidth. The RTX PRO 2000 Blackwell also features a much larger compute configuration: 4,352 shading units, 136 TMUs, and 48 ROPs, versus 512 shading units, 32 TMUs, and 16 ROPs on the GTX 1630.

Memory configuration is starkly different: 16 GB GDDR7 versus 4 GB GDDR6, with 128-bit versus 64-bit bus widths. The RTX PRO 2000 Blackwell has 4,352 shading units, 136 TMUs, 48 ROPs, 34 RT cores, and 136 tensor cores. The GTX 1630 has 512 shading units, 32 TMUs, and 16 ROPs, with no RT or tensor cores.

The RTX PRO 2000 Blackwell uses a PCIe 5.0 x8 interface, while the GTX 1630 uses PCIe 3.0 x16. Display outputs also differ: the RTX PRO 2000 Blackwell has 4x mini-DisplayPort 2.1b, while the GTX 1630 has 1x DVI, 1x HDMI 2.0, and 1x DisplayPort 1.4a.

Where Each One Wins

The RTX PRO 2000 Blackwell wins every category that matters for modern computing. Its 380.5% lead in Vulkan indicates superior performance in gaming and real-time graphics workloads that leverage low-level APIs. The 326.8% lead in OpenCL shows dominance in compute-heavy tasks like rendering, simulation, and machine learning inference. With 16 GB of GDDR7 memory and 288.0 GB/s of bandwidth, it can handle large datasets and high-resolution textures that the 4 GB GTX 1630 cannot even load.

The GTX 1630 has no wins in any benchmark category. Its only potential advantage is physical: it is a single-slot card at 145 mm length, making it easier to fit in compact systems. It also has a marginally lower TDP of 75 W versus 70 W for the RTX PRO 2000 Blackwell, though this is negligible. Its PCIe 3.0 x16 interface is wider than the RTX PRO 2000 Blackwell’s PCIe 5.0 x8, but the newer standard’s bandwidth advantage makes this moot. The GTX 1630 also offers a DVI output, which the RTX PRO 2000 Blackwell lacks, but this is a legacy connector with limited modern use.

The Verdict

The RTX PRO 2000 Blackwell is the only rational choice for any workload involving modern graphics or compute. Its Vulkan score of 113,865 is 380.5% higher than the GTX 1630’s 23,695, and its OpenCL score of 106,087 is 326.8% higher than 24,858. The RTX PRO 2000 Blackwell also holds a 70th percentile ranking among all GPUs, while the GTX 1630’s percentile is also 70, but this is misleading given the former’s far higher absolute scores and the latter’s end-of-life status.

The GTX 1630 is a legacy product from the GeForce 16 generation, using Turing architecture with no ray tracing or tensor cores. The RTX PRO 2000 Blackwell, by contrast, is an active Blackwell PRO W product with 34 RT cores, 136 tensor cores, and 17.03 TFLOPS of FP32 compute. For anyone building a new system, the GTX 1630’s 4 GB of memory and 96.00 GB/s bandwidth are severe bottlenecks, while the RTX PRO 2000 Blackwell’s 16 GB of GDDR7 at 288.0 GB/s provides ample headroom.

The data supports a single conclusion: the RTX PRO 2000 Blackwell is categorically superior in performance, features, and memory capacity. The GTX 1630 should only be considered for legacy systems requiring a DVI output or where the single-slot form factor is mandatory. In every benchmark, the RTX PRO 2000 Blackwell wins by a factor of at least four, making this comparison one of the most lopsided in the database.
