NVIDIA GeForce GTX 1630 vs NVIDIA GeForce GTX TITAN Z Comparison

The GeForce GTX 1630 and the GeForce GTX TITAN Z represent two very different answers to the same question: what does an NVIDIA GPU look like? The GTX 1630 is a modern, low-power Turing-based card, while the TITAN Z is a dual-GPU Kepler behemoth from a previous era. Benchmark results show a split decision: the TITAN Z wins in OpenCL by a small margin, but the GTX 1630 takes a clear victory in Vulkan. The data shows that these two cards trade blows in ways that defy their architectural differences.

Architecture Differences

The two GPUs are built on completely different foundations. The GTX 1630 uses the TU117 chip, based on the Turing architecture, and is manufactured on a 12 nm process at TSMC. It contains 4,700 million transistors on a die size of 200 mm², resulting in a transistor density of 23.5M / mm². In contrast, the TITAN Z uses the GK110B chip, based on the older Kepler architecture, and is built on a 28 nm process, also at TSMC. This older process means the TITAN Z packs 7,080 million transistors onto a much larger 561 mm² die, with a lower transistor density of 12.6M / mm².

The memory subsystems are also fundamentally different. The GTX 1630 comes with 4 GB of GDDR6 memory on a 64-bit bus, providing a bandwidth of 96.00 GB/s. The TITAN Z features 6 GB of GDDR5 memory on a 384-bit bus, delivering a much higher bandwidth of 336.0 GB/s. The TITAN Z also has far more compute resources on paper, with 2880 shading units, 240 TMUs, and 48 ROPs, versus the GTX 1630’s 512 shading units, 32 TMUs, and 16 ROPs. The TITAN Z’s raw throughput numbers are correspondingly higher, with a pixel rate of 52.56 GPixel/s and a texture rate of 210.2 GTexel/s, compared to the GTX 1630’s 28.56 GPixel/s and 57.12 GTexel/s. The FP32 performance is also lopsided, with the TITAN Z at 5.046 TFLOPS versus the GTX 1630’s 1.828 TFLOPS.

The feature sets differ due to their generations. The GTX 1630 supports DirectX 12 (12_1) and Vulkan 1.4, while the TITAN Z supports DirectX 12 (11_1) and Vulkan 1.2.175. Both support OpenGL 4.6. The GTX 1630’s display outputs include 1x DVI, 1x HDMI 2.0, and 1x DisplayPort 1.4a, while the TITAN Z offers 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The TITAN Z is a dual-GPU card, which explains its triple-slot design and massive power draw.

Head-to-Head Benchmarks

The benchmark results from the data paint a fascinating picture of generational progress versus raw hardware power. In the Geekbench OpenCL test, the TITAN Z emerges as the winner with a score of 25,465, beating the GTX 1630’s 24,858. The delta is 2.4% in favor of the older card. This suggests that in compute-heavy workloads that scale well with raw shading units and memory bandwidth, the TITAN Z’s massive 2880 shading units and 336.0 GB/s bandwidth can overcome its older architecture and lower clocks.

However, the tables turn completely in the Geekbench Vulkan test. Here, the GTX 1630 wins with a score of 23,695, versus the TITAN Z’s 22,006. This is a 7.7% victory for the GTX 1630. Vulkan is a modern API that benefits from newer architectural features and driver optimizations. The GTX 1630’s Turing architecture, with its 12 nm process and support for newer instruction sets, appears to be much more efficient in this workload. The TITAN Z’s older Kepler architecture and dual-GPU configuration may not scale as well in Vulkan, leading to a significant deficit.

The overall picture is one of a tie, with each card winning one benchmark. The TITAN Z’s win in OpenCL is narrow, but its loss in Vulkan is more pronounced. This indicates that while the TITAN Z has brute force on its side, the GTX 1630 has efficiency and modern API support that closes the gap and even surpasses it in certain scenarios. The data shows that the TITAN Z’s theoretical compute advantage does not translate into a universal real-world win.

The Verdict

The data suggests a clear split based on workload. The NVIDIA GeForce GTX 1630 is the better choice for users who prioritize modern API performance, lower power consumption, and a compact physical footprint. Its 7.7% lead in Vulkan is significant, and its 75 W TDP with no power connectors makes it trivial to install in almost any system. The TITAN Z, on the other hand, is for those who need raw compute throughput in OpenCL-heavy applications. Its 2.4% win in that test, combined with its massive 6 GB memory frame buffer and 384-bit bus, makes it a niche pick for specific workloads.

For a general-purpose card, the GTX 1630 is the more practical choice. It is end-of-life but so is the TITAN Z. The GTX 1630’s higher average benchmark score of 24,277 versus 23,736 shows it is the better all-rounder. The TITAN Z’s launch MSRP of 2,999 USD was astronomically higher, but its performance does not justify that cost in modern terms, especially given its power draw of 375 W and need for a 750 W PSU. The GTX 1630, with its single-slot design and 250 W suggested PSU, is a far more manageable piece of hardware.

Where Each One Wins

The GTX 1630 wins in scenarios that favor modern API utilization and efficiency. Its 7.7% lead in the Vulkan benchmark is the key differentiator. If you are building a system for games or applications that use Vulkan, the GTX 1630 is the clear victor. Its low power draw of 75 W and single-slot design also make it the winner for small form factor builds or upgrades to older systems with modest power supplies. The data shows it is the more balanced card, with a higher overall average score.

The TITAN Z wins in raw compute throughput, as evidenced by its 2.4% lead in OpenCL. This makes it the pick for workloads that are heavily optimized for OpenCL and can leverage its 2880 shading units and 336.0 GB/s of memory bandwidth. Its 6 GB frame buffer also gives it an edge in memory capacity for large datasets. However, this comes at a steep cost in power and size. The TITAN Z requires a triple-slot footprint and a 750 W PSU, which limits its practicality. For users who have the power budget and need maximum OpenCL compute, the TITAN Z is the data-backed winner. For everyone else, the GTX 1630 offers the better overall package.
