NVIDIA GeForce GTX 780 6 GB Specifications

GeForce GTX 780 6 GB GPU Core

Shader units and compute resources

The NVIDIA GeForce GTX 780 6 GB GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.

About NVIDIA GeForce GTX 780 6 GB

The NVIDIA GeForce GTX 780 6 GB is a Kepler-architecture card from the GeForce 700 generation, built on a 28 nm process at TSMC. It packs 7,080 million transistors into a 561 mm² die, and its 6 GB GDDR5 frame buffer sits on a 384-bit bus. With a boost clock of 902 MHz, it delivers 4.156 TFLOPS of FP32 compute. This card is end-of-life and occupies the 50th percentile of all GPUs in the database, meaning it sits exactly at the midpoint of the performance distribution.

Memory Subsystem

The GTX 780 6 GB carries 6 GB of GDDR5 memory on a 384-bit interface, yielding a bandwidth of 288.4 GB/s. The memory clock is listed as 1502 MHz, which translates to 6 Gbps effective data rate. This combination of capacity and bandwidth is substantial for its era: 6 GB allows large textures and high-resolution assets to reside locally, while the 384-bit bus keeps the data flowing to the GPU cores. At 1440p or 4K, memory bandwidth often becomes a bottleneck; the 288.4 GB/s figure is high enough to feed the 2304 shading units without stalling in most scenarios of the time. The pixel rate of 43.30 GPixel/s and texture rate of 173.2 GTexel/s, both derived from the 902 MHz boost clock, further indicate that the memory subsystem can keep up with the render output and texture fetch demands. For modern use, the 6 GB capacity is still useful for modded games or high-res texture packs, though the lack of newer compression techniques may reduce effective bandwidth compared to newer cards.

Ray Tracing and Feature Set

This GPU has no dedicated ray tracing cores and no tensor cores — the fact pack lists both as null. Hardware-accelerated ray tracing is therefore absent. Instead, the card relies on traditional rasterization. Its API support includes DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.175. The DirectX 12 feature level 11_1 means it can run DX12 titles in compatibility mode, but it lacks features like variable-rate shading or mesh shaders that rely on newer hardware. Vulkan 1.2.175 offers broad compatibility with modern Vulkan titles, though again without ray tracing extensions. The display outputs are 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, which covers multi-monitor setups but does not support HDMI 2.1 or DisplayPort 2.0. For users interested in ray tracing or AI-accelerated features like DLSS, this card is not suitable; it is purely a rasterization part.

How It Compares

The fact pack provides no nearest rival data for this GPU, so direct comparisons to specific competing models are not possible from the given information. However, its position in the database is clear: the 50th percentile of all GPUs indicates that it outperforms half of the entries and is outperformed by the other half. In terms of generational lineage, the card belongs to the GeForce 700 series, with the predecessor being the GeForce 600 series and the successor being the GeForce 900 series. That places it in the middle of NVIDIA's Kepler-to-Maxwell transition. Without rival scores, the percentile is the only objective benchmark-relative metric available. The lack of benchmark scores in the fact pack means no delta percentages can be computed against other cards. The card's theoretical performance, as expressed by its FP32 throughput and memory bandwidth, suggests it was a high-end part at launch, but its exact standing among contemporaries must be inferred from the percentile alone.

FAQ

Q: How much VRAM does the GTX 780 6 GB have?

A: It has 6 GB of GDDR5 memory on a 384-bit bus, providing 288.4 GB/s of bandwidth.

Q: Does this card support hardware ray tracing?

A: No. The fact pack lists no RT cores and no tensor cores, so ray tracing and AI-accelerated features are not available.

Q: What is the recommended power supply for this GPU?

A: The suggested PSU is 600 W. The card itself has a TDP of 250 W and requires one 6-pin and one 8-pin power connector.

Q: What API versions are supported?

A: It supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.175.

Q: What is the production status of this card?

A: It is end-of-life, meaning it is no longer manufactured.

Q: What display outputs are available?

A: It has 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2.

Benchmark Performance

The fact pack does not include any benchmark scores for this GPU; the avgBenchmarkScore is 0, and the nearestRivals list is empty. The only relative performance indicator is the percentileVsAllGpus value of 50, which places it exactly at the median of all GPUs in the database. This means that, based on the database's aggregate data, the card is neither a standout performer nor a laggard — it sits in the middle of the pack. While no direct rival deltas can be calculated, the theoretical compute metrics give a sense of its raw capability: FP32 throughput is 4.156 TFLOPS, pixel rate is 43.30 GPixel/s, and texture rate is 173.2 GTexel/s. These numbers are derived from the 2304 shading units, 192 TMUs, and 48 ROPs operating at a boost clock of 902 MHz. The memory bandwidth of 288.4 GB/s is substantial for a 384-bit GDDR5 configuration. In practical terms, the card can handle 1080p and 1440p gaming from its generation with high settings, but the lack of modern features and the 50th percentile standing suggest it would struggle with current AAA titles at high resolutions. The absence of benchmark scores means any performance comparison must rely on these theoretical figures and the percentile placement.

Power and Cooling

The GTX 780 6 GB has a TDP of 250 W, which is typical for a high-end Kepler card. NVIDIA recommends a 600 W power supply, and the card draws power through one 6-pin and one 8-pin PCIe connector. The dual-slot cooler is 267 mm long, 111 mm tall, and 38 mm wide, so it will fit in most mid-tower cases, but clearance should be checked. The 28 nm process and 7,080 million transistors generate considerable heat, so a capable air cooler is required; the dual-slot design is standard for that era. The card's power draw is not trivial — 250 W under load means the rest of the system needs adequate headroom, and the 600 W PSU recommendation accounts for that. Users with older power supplies should verify that they have the necessary 6-pin and 8-pin connectors, as adapters are not mentioned. The card's end-of-life status means that driver optimizations may have slowed, but the power and cooling requirements remain as specified. For a modern system, this card would be a power-hungry choice, but its thermal solution is adequate for its rated TDP.
