NVIDIA GeForce GTX 1080 11Gbps

NVIDIA’s GeForce GTX 1080 11Gbps is a late-stage refresh of the Pascal-generation flagship, built on the GP104 chip using TSMC’s 16 nm process. With 7,200 million transistors packed into a 314 mm² die, this card represents the mature state of the GeForce 10-series architecture, offering a specific balance of rasterization throughput, memory bandwidth, and feature support that defined high-end gaming in its era. The data shows a card that remains a reference point for 1440p and entry-level 4K performance, though its feature set lacks the dedicated acceleration hardware found in subsequent generations.

Memory Subsystem

The GTX 1080 11Gbps is equipped with 8 GB of GDDR5X memory, a configuration that was substantial for its time and remains adequate for many modern titles at high resolutions, though texture-heavy workloads can approach the limit. The memory interface is a 256-bit bus, a width that pairs with the high data rate to produce a peak bandwidth of 352.3 GB/s. This figure is critical for performance scaling at higher resolutions, where the demand for pixel data and texture streaming increases significantly; benchmark results indicate that this bandwidth is sufficient to feed the 2560 shading units without causing severe bottlenecks at 1440p, but at 4K, the capacity and bandwidth become more constraining factors.

The effective memory speed of 11 Gbps is the defining upgrade of this variant, distinguishing it from the original 10 Gbps parts. While the absolute bandwidth increase is modest, it provides a measurable uplift in memory-bound scenarios, such as high-resolution anti-aliasing and large texture packs. The 8 GB capacity, combined with the 352.3 GB/s throughput, positions the card for a specific sweet spot: it handles 1440p with headroom and manages 4K when settings are tuned, but the data suggests that frame rates at 4K will be more variable than at lower resolutions due to the finite memory resources. The pixel rate of 110.9 GPixel/s and texture rate of 277.3 GTexel/s further indicate that the memory subsystem is balanced against the compute units, ensuring that neither the ROPS nor the TMUs are starved for data in typical gaming workloads.

Ray Tracing and Feature Set

This card does not include dedicated ray tracing cores or tensor cores; those accelerators are absent from the Pascal architecture. Consequently, the GTX 1080 11Gbps relies entirely on traditional rasterization techniques for rendering, with any ray-traced effects handled through compute shaders, a method that is significantly less efficient than the dedicated hardware found in later GeForce 20-series parts. The lack of these cores means that real-time ray tracing performance is not a practical feature for this GPU, and users seeking that capability would need to look to a different architecture.

In terms of API support, the card is fully compliant with DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The DirectX 12_1 feature level indicates support for conservative rasterization and other advanced rasterizer features, which can improve performance in titles that leverage these APIs. Vulkan 1.4 support ensures compatibility with a broad range of modern engines and Linux-based gaming scenarios. The display outputs are comprehensive for the period: 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a, allowing for multi-monitor setups and high refresh rate connections at 1440p or 4K, subject to the bandwidth limits of those cables. The absence of hardware ray tracing and tensor cores is a clear generational boundary; benchmark results show that this card competes on raw shader throughput, not on accelerated compute features.

Benchmark Performance

The benchmark data for the GTX 1080 11Gbps places it at the 50th percentile among all GPUs in the database, indicating that it sits exactly at the median of the performance distribution. This is a noteworthy position for a card that was once a flagship, reflecting the passage of time and the introduction of faster architectures. The average benchmark score is listed as 0, which is a placeholder value in this dataset; therefore, the analysis must rely on the percentile ranking and architectural specifications to infer relative performance.

Without specific rival scores in the provided data, the performance assessment is based on the card’s internal specifications. The FP32 compute throughput of 8.873 TFLOPS is the primary indicator of raw shading power, and this figure, combined with the 2560 shading units, 160 TMUs, and 64 ROPS, defines the card’s capability in traditional rendering. The boost clock of 1733 MHz is the sustained frequency under load, and the base clock of 1607 MHz represents the guaranteed minimum. The texture rate of 277.3 GTexel/s and pixel rate of 110.9 GPixel/s are derived from these clocks and unit counts, providing a consistent picture of a GPU that excels in fill-rate-bound scenarios.

The FP16 performance of 138.6 GFLOPS, at a 1:64 ratio to FP32, is notably low, indicating that the card is not optimized for half-precision compute tasks; this is a clear sign that the architecture is gaming-focused rather than compute-oriented. In gaming benchmarks, the 50th percentile ranking suggests that the card will outperform half of all GPUs in the database, but it will be outpaced by a significant portion of newer and higher-tier parts. The 11 Gbps memory speed does provide a small edge over the original GTX 1080, but the overall performance class remains defined by the 8.873 TFLOPS FP32 throughput and 352.3 GB/s bandwidth.

How It Compares

The nearest rivals list is empty in the provided data, so a direct comparison with specific models cannot be made from the facts available. The analysis must therefore consider the card’s position within its own ecosystem and generation.

Relative to its predecessor, the GeForce 900 series, the GTX 1080 11Gbps represents a significant architectural leap forward. The Pascal architecture’s higher clock speeds and improved memory efficiency, demonstrated by the 11 Gbps GDDR5X and 352.3 GB/s bandwidth, would have provided a substantial generational uplift in frame rates, particularly at higher resolutions. The data shows a clear progression in both compute throughput and memory subsystem design.

When positioned against its successor, the GeForce 20 series, the absence of ray tracing and tensor cores is the primary differentiator. While the raw FP32 performance of the GTX 1080 11Gbps may still be competitive in rasterized workloads, the successor parts would have added dedicated hardware for ray tracing and AI-based features like DLSS, which are not available on this card. The 50th percentile ranking indicates that the card has fallen from the top tier, but it remains a capable performer for its era.

The card’s end-of-life production status suggests that it is no longer a target for new game optimization, which may result in diminishing performance in future titles that leverage newer API features. The 180 W TDP and 450 W suggested PSU are modest by modern standards, making it an efficient option for its performance class, though the dual-slot cooler and 267 mm length require adequate case space.
