NVIDIA GeForce GTX 1080 Ti

The NVIDIA GeForce GTX 1080 Ti, built on the Pascal architecture with the GP102 chip, remains a high-water mark for the GeForce 10-series generation. Produced on TSMC’s 16 nm process with 11,800 million transistors on a 471 mm² die, this card delivers an average benchmark score of 19402, placing it at the 61st percentile of all GPUs. Its specifications include 3584 shading units, 224 texture mapping units, and 88 ROPs, with peak rates of 139.2 GPixel/s and 354.4 GTexel/s. The FP32 throughput is 11.34 TFLOPS, while FP16 is severely reduced at 177.2 GFLOPS (1:64). The card operates at a base clock of 1481 MHz and a boost clock of 1582 MHz, drawing a 250 W TDP and requiring a 600 W suggested PSU. With a launch MSRP of 699 USD, it was positioned as a flagship, and its end-of-life status now places it in the used or legacy market.

Benchmark Performance

The GTX 1080 Ti’s average benchmark score of 19402 establishes a baseline that is remarkably consistent with its nearest rivals, yet the distribution of performance across specific tests reveals where its Pascal architecture excels. In 3DMark Steel Nomad DX12, the card posts a score of 2231, a result that highlights its capability in modern API workloads, though this is not its strongest metric compared to legacy tests. The Geekbench suite shows a mixed profile: Metal yields 30624, OpenCL reaches 67717, and Vulkan peaks at 83108. These numbers indicate that the card’s compute throughput is heavily dependent on the API, with Vulkan delivering over 2.7 times the Metal score, suggesting strong driver optimization for cross-platform workloads.

PassMark results further dissect the performance envelope. DirectX 9 scoring 231, DirectX 10 at 118, and DirectX 11 at 151 show that older APIs run efficiently, but DirectX 12 drops to 66, which implies that the Pascal architecture’s feature level 12_1 may not fully leverage newer DX12 optimization paths. The PassMark G3D score of 18600 and GPU Compute score of 9632 demonstrate that rasterization and compute are well-balanced, though the G2D score of 939 is modest, indicating that 2D operations were not a design priority. The average score of 19402 aligns closely with the aggregate of these diverse tests, but the variance across APIs is a key consideration for anyone targeting specific workloads.

Relative to its nearest rivals, the GTX 1080 Ti is statistically tied with the NVIDIA GeForce GTX 780, which scores 19405 with a deltaPct of 0. The AMD Radeon Pro 560X is effectively identical at 19426 with a deltaPct of -0.1, meaning the 1080 Ti is 0.1% behind—a negligible margin. The NVIDIA Tesla K40m trails at 19519 with a -0.6 deltaPct, placing the 1080 Ti 0.6% ahead. Most notably, the NVIDIA TITAN Xp scores 19184 with a deltaPct of 1.1, which means the 1080 Ti is 1.1% faster than its direct sibling, a surprising inversion given the TITAN Xp’s typical positioning. These deltas are all within 1.2 percentage points, underscoring that this generation’s performance ceiling was tightly clustered across high-end SKUs.

Ray Tracing and Feature Set

The GTX 1080 Ti does not include dedicated ray tracing cores or tensor cores; its architecture predates the RTX line, relying instead on traditional CUDA cores for all graphics and compute tasks. The API support includes DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, which means the card can run modern games and applications that use these interfaces, but without hardware-accelerated ray tracing, any such workloads must fall back to compute-based methods, which are significantly less efficient. The absence of tensor cores also precludes AI-accelerated features like DLSS, which require dedicated hardware to function properly.

The feature set is robust for its era, with display outputs of 1x HDMI 2.0 and 3x DisplayPort 1.4a, supporting high refresh rates and multi-monitor setups. The PCIe 3.0 x16 interface is standard, and the dual-slot design with 1x 6-pin and 1x 8-pin power connectors fits typical high-end power delivery. The Pascal architecture’s strength lies in its raw rasterization throughput, as evidenced by the 11.34 TFLOPS FP32, but its FP16 capability at 177.2 GFLOPS (1:64) is negligible, meaning mixed-precision workloads that benefit from FP16 acceleration will see no advantage. For users reliant on Vulkan 1.4, the 83108 Geekbench Vulkan score demonstrates solid driver maturity, but the lack of ray tracing and tensor cores fundamentally limits the card’s relevance in modern feature-heavy titles.

Memory Subsystem

The memory configuration is one of the GTX 1080 Ti’s defining characteristics: 11 GB of GDDR5X on a 352-bit bus delivers 484.4 GB/s of bandwidth. This is a substantial amount of VRAM for its generation, sufficient for high-resolution textures and large datasets. The effective memory clock is 11 Gbps, which, when combined with the 352-bit interface, yields the 484.4 GB/s figure. The memory runs at 1376 MHz base in the clock specifications, but the effective 11 Gbps is the operational throughput metric.

This bandwidth is critical for 4K gaming and compute workloads that stream large data sets. The 11 GB capacity allows for ultra-high texture packs in games that were designed for this era, and the 484.4 GB/s ensures that the 3584 shading units are fed without bottlenecks in most scenarios. However, the 352-bit bus, while wide, is narrower than some later flagship cards, but the GDDR5X speed compensates. The pixel rate of 139.2 GPixel/s and texture rate of 354.4 GTexel/s are consistent with the memory bandwidth, ensuring balanced performance. For resolutions beyond 4K or for multi-tasking with multiple displays, the 484.4 GB/s might become a limiting factor, but for its intended 1440p and 4K workloads, the memory subsystem is more than adequate.

Who Should Consider It

Benchmark results indicate that the GTX 1080 Ti is best suited for 1440p and 4K gaming at high settings, provided the user is not seeking ray tracing or AI-enhanced features. The 3DMark Steel Nomad DX12 score of 2231 and PassMark G3D of 18600 suggest that modern titles at 1440p will run smoothly, while 4K is achievable with adjusted settings, particularly in games that are not VRAM-hungry beyond the 11 GB capacity. The Vulkan score of 83108 on Geekbench makes it a competent choice for Vulkan-based games, which often show strong scaling on Pascal hardware.

Users with legacy game collections will find the DirectX 9 score of 231 and DirectX 11 score of 151 indicative of solid performance in older APIs, but the DirectX 12 score of 66 is a warning sign for newer DX12 titles that rely on advanced features. Compute users focusing on OpenCL will see the 67717 Geekbench score, which is respectable for its time but not competitive with modern accelerators. The 61st percentile ranking means it outperforms about 61% of all GPUs in the database, but it is no longer a top-tier performer. For those who have a 600 W PSU already and can accommodate a 267 mm dual-slot card, the GTX 1080 Ti remains a viable option for 1440p high-refresh-rate gaming, but it is not recommended for users who prioritize ray tracing or need FP16 acceleration.

How It Compares

Against the NVIDIA GeForce GTX 780, the GTX 1080 Ti is exactly tied, with both scoring 19405 and 19402 respectively, showing a deltaPct of 0. This is surprising because the GTX 780 is an older Kepler-generation card, but the average benchmark scores suggest that in aggregate, they perform identically. The 1080 Ti’s higher memory bandwidth and newer architecture do not translate into a measurable advantage in these tests, indicating that the GTX 780’s legacy driver optimizations or test conditions level the playing field.

The AMD Radeon Pro 560X, a mobile workstation GPU, scores 19426 with a deltaPct of -0.1, meaning the 1080 Ti is 0.1% slower. This margin is within noise, and the 1080 Ti’s desktop-class cooling and power delivery make it more sustainable for prolonged workloads, but the benchmark data alone shows no meaningful difference. The Pro 560X’s lower TDP and compact size might appeal to certain users, but the 1080 Ti offers far superior raw specifications that these aggregate scores do not fully capture.

The NVIDIA Tesla K40m, a compute-focused card, scores 19519 with a deltaPct of -0.6, placing the 1080 Ti 0.6% ahead. The Tesla K40m’s higher average score is odd given its older Kepler architecture, but the 1080 Ti’s 11 GB VRAM and 484.4 GB/s bandwidth provide a more balanced gaming and compute experience, whereas the Tesla lacks display outputs and is optimized for server workloads.

The NVIDIA TITAN Xp, which shares the GP102 chip, scores 19184 with a deltaPct of 1.1, meaning the 1080 Ti is 1.1% faster. This is the most notable comparison because the TITAN Xp is typically considered a higher-tier product, yet the data shows the 1080 Ti outperforms it in average benchmark scores. The 1080 Ti’s lower launch MSRP of 699 USD compared to the TITAN Xp’s typical pricing makes it a more rational choice, but the benchmark delta is small enough that real-world differences are minimal. Overall, the GTX 1080 Ti sits in a tight performance cluster with all four rivals, with deltas never exceeding 1.2%, meaning that any of these cards would deliver nearly identical average performance, and the decision should be based on features like VRAM capacity, power efficiency, or availability rather than raw scores.
