About NVIDIA GeForce GTX 770
The NVIDIA GeForce GTX 770, built on the Kepler architecture with the GK104 chip, occupies a specific niche in the benchmark hierarchy. With an average benchmark score of 14,536, it sits at the 56th percentile of all GPUs, placing it in the mid-range tier of performance. The data indicates a card that remains competitive in specific workloads, though it clearly trails modern counterparts in raw throughput.
Memory Subsystem
The GTX 770 comes equipped with 2 GB of GDDR5 memory on a 256-bit bus, yielding a bandwidth of 224.4 GB/s. This configuration was designed for 1080p gaming, where the memory capacity and bandwidth are generally sufficient for textures and assets of that era. The effective memory clock runs at 7 Gbps, which was a high figure at release and contributes to the card's ability to push data in bandwidth-sensitive scenarios. However, the 2 GB capacity is a limiting factor at higher resolutions; modern titles with high-resolution texture packs can easily exceed this allocation, leading to potential stuttering or texture pop-in when the buffer is exceeded.
Benchmark results indicate that the memory subsystem performs adequately relative to its peers. The GTX 770's bandwidth is a clear advantage over the AMD Radeon Pro 555X, which scores 0.2% lower overall, and the AMD Radeon RX 5500 XT, which sits 1% behind. In contrast, the NVIDIA GeForce GTX 1070 Ti, which leads this group by 1.2%, benefits from a more modern memory architecture that is better equipped for 1440p and 4K workloads. For the GTX 770, the practical ceiling is 1080p; pushing beyond that requires compromises in texture quality or resolution scaling.
Ray Tracing and Feature Set
The GTX 770 does not include dedicated ray tracing or tensor cores, as these technologies were not part of the Kepler architecture. Its feature set is defined by the APIs it supports: DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. DirectX 12 support at the 11_0 feature level means the card can run games using that API, but it lacks the advanced features of newer hardware, such as hardware-accelerated ray tracing. Similarly, Vulkan support is present, allowing for cross-platform compatibility, but the absence of dedicated RT cores means any ray-traced effects would rely on compute shaders, which is inefficient on this architecture.
The display outputs include 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2, providing flexibility for multi-monitor setups. The lack of tensor cores also means no DLSS or AI-based upscaling, which is a significant drawback compared to newer cards. For users relying on the GTX 770, the feature set is functional for traditional rasterization but offers no path forward for modern rendering techniques. The card's 1536 shading units and 128 TMUs provide the computational base for its 3.333 TFLOPS of FP32 performance, but this is a fixed resource that cannot be augmented by specialized hardware.
Benchmark Performance
The Geekbench results for the GTX 770 show a spread across different compute APIs. In Geekbench Metal, it scores 8,281, while in OpenCL it reaches 17,607, and in Vulkan it peaks at 17,719. The Vulkan score is the strongest, indicating that the card's drivers and hardware handle this API well, potentially due to lower overhead. The OpenCL score is nearly identical, suggesting consistent performance across general-purpose compute workloads. The Metal score is notably lower, which may reflect driver maturity or API-specific limitations on this older architecture.
Against its nearest rivals, the GTX 770 is essentially tied with the NVIDIA Quadro M2000, which has an average score of 14,532, a delta of 0%. This suggests that for professional compute tasks, the two cards are interchangeable in performance. The AMD Radeon Pro 555X is 0.2% behind, which is within the margin of error, indicating a statistical dead heat. The AMD Radeon RX 5500 XT is 1% slower, a small but measurable gap that shows the GTX 770 can still edge out a much newer card in synthetic benchmarks. The NVIDIA GeForce GTX 1070 Ti, however, is 1.2% faster, which is a modest lead but one that widens in real-world gaming scenarios due to its superior memory subsystem and architecture.
The average benchmark score of 14,536, combined with the 56th percentile ranking, tells a clear story: the GTX 770 is a competent mid-ranger that holds its own against similar-class GPUs. It is not a high-end performer, but it is far from obsolete in compute tasks. The 1% lead over the RX 5500 XT is particularly noteworthy, as it demonstrates that raw compute power from 2013 can still match a 2019 entry-level card in API-agnostic tests.

Who Should Consider It
The GTX 770 is a card for users working within the constraints of 1080p resolution and older game titles. Its 2 GB VRAM and 224.4 GB/s bandwidth are sufficient for medium to high settings in games released before its end-of-life date, but they will struggle with modern titles at high texture quality. Benchmark data shows it is statistically tied with the Quadro M2000 and only 0.2% faster than the Radeon Pro 555X, making it a viable option for basic compute tasks or as a placeholder card in a legacy system.
For those considering it for gaming, the 1% lead over the RX 5500 XT in synthetic benchmarks is misleading; the newer card has better driver support and more VRAM in some variants. The GTX 770's lack of ray tracing and tensor cores means it cannot handle modern rendering features, so it is not recommended for new builds. However, for someone with an existing system that already has a 550W PSU and the required 1x 6-pin + 1x 8-pin power connectors, the GTX 770 can serve as a stopgap for 1080p eSports titles or older AAA games. The 1.2% deficit to the GTX 1070 Ti is significant in gaming, but in compute workloads, the gap is minimal, making the GTX 770 a reasonable choice for users who prioritize OpenCL or Vulkan compute over gaming performance. Given its end-of-life status, it is best suited for those who already own one or find it at a substantial discount, not for those seeking a future-proof solution.
