NVIDIA GeForce GTX 550 Ti

The NVIDIA GeForce GTX 550 Ti is an end-of-life graphics card built on the Fermi 2.0 architecture, using the GF116 chip manufactured on TSMC’s 40 nm process. With a Geekbench OpenCL score of 5731, it lands in the 32nd percentile of all GPUs, placing it firmly in entry-level territory for its era. The card’s 192 shading units, 32 texture mapping units, and 24 ROPs deliver a raw FP32 compute rate of 691.2 GFLOPS, but its modest specifications and dated feature set mean it is best suited for legacy systems or low-resolution gaming. The data shows a card that was competitive at launch in 2011 but now trails modern integrated graphics in several workloads.

Power and Cooling

The GTX 550 Ti carries a thermal design power (TDP) of 116 W, which is modest by contemporary standards but still requires dedicated power delivery. The card uses a single 6-pin PCIe power connector, and the suggested power supply unit rating is 300 W. This combination makes the card relatively undemanding on system power budgets, though it is not a zero-maintenance drop-in upgrade for older prebuilt PCs lacking a 6-pin header. The dual-slot cooler design is typical of the generation, providing adequate thermal dissipation for the 116 W envelope without exotic cooling solutions. The card measures 210 mm (8.3 inches) in length, which fits most mid-tower cases but may require checking clearance in compact builds. The bus interface is PCIe 2.0 x16, which is backward compatible with newer slots but may bottleneck on modern platforms due to reduced bandwidth headroom. Because the TDP is modest and the power connector requirement is a single 6-pin, users with a 300 W PSU from a reputable brand can run the card without upgrading their power supply, assuming the rest of the system is not power-hungry.

Ray Tracing and Feature Set

The GTX 550 Ti has no dedicated ray tracing cores and no tensor cores, as these features were introduced in later NVIDIA architectures. The card’s API support is limited to DirectX 12 (11_0), meaning it can run DirectX 12 titles only in their 11_0 feature-level mode, which excludes many modern rendering techniques like mesh shaders or variable rate shading. OpenGL 4.6 is supported, which allows basic compatibility with older OpenGL applications. Vulkan support is not listed, so users cannot rely on that API for newer games or emulators. The display outputs include 2x DVI and 1x mini-HDMI 1.3a, which limits connectivity to older monitors or requires adapters for DisplayPort-only displays. The lack of hardware ray tracing means any ray-traced effects in games must be handled through software fallbacks, which is impractical given the card’s low compute throughput. The pixel rate is 7.200 GPixel/s and the texture rate is 28.80 GTexel/s, both of which are far below what modern games require for high-fidelity effects. In short, this card is not a candidate for ray tracing or advanced feature workloads; it is a rasterization-only part from a pre-RTX era.

Who Should Consider It

Benchmark results indicate that the GTX 550 Ti achieves a Geekbench OpenCL score of 5731, which places it in the 32nd percentile of all GPUs. This score suggests the card can handle 720p gaming at low to medium settings for titles from its release era (2011 and earlier), but it will struggle with 1080p high-settings gaming in anything released after 2013. For users running legacy operating systems or older games that do not demand high geometry or shader complexity, the card remains functional. The 1024 MB VRAM capacity is a hard limit: modern games at 1080p often require 2-4 GB, so this card is unsuitable for those workloads. Resolution-wise, the card is best paired with 1280x720 or 1366x768 displays, where its 98.50 GB/s bandwidth and 691.2 GFLOPS can keep frame rates playable in undemanding titles. Users who need a card for office productivity, 2D desktop acceleration, or retro gaming emulation will find it adequate, but anyone expecting modern AAA gaming at 1080p should look elsewhere. The 32nd percentile ranking confirms that it sits below the median GPU, so it is not a general-purpose recommendation for current workloads.

How It Compares

NVIDIA Quadro K4000 — The GTX 550 Ti scores 5731 against the Quadro K4000’s 5723, a delta of 0.1% in favor of the GTX. This is a statistical tie; in practical terms, the two cards are interchangeable in compute tasks. The Quadro’s professional driver optimizations may favor specific CAD or OpenGL workloads, but raw OpenCL performance is nearly identical.

NVIDIA GeForce GTX 670MX — The GTX 550 Ti trails the GTX 670MX by 0.2% (5731 vs 5742). This delta is negligible, meaning the two perform within noise margins. The GTX 670MX is a mobile part, so the comparison is only relevant for users comparing desktop and laptop performance from that generation.

Intel Iris Pro Graphics P6300 — The GTX 550 Ti is 0.3% ahead of the Iris Pro P6300 (5731 vs 5712). This is a narrow lead, but it shows that a high-end integrated GPU from Intel’s Broadwell era can nearly match a discrete Fermi card. The GTX still holds a slight edge, but the margin is not enough to justify a discrete card purchase today.

Intel UHD Graphics P630 — The GTX 550 Ti is 0.5% behind the UHD P630 (5731 vs 5760). This is a surprising result, as the UHD P630 is an integrated solution found in many business laptops. The data indicates that modern integrated graphics have caught up with and slightly surpassed this Fermi-era discrete card in OpenCL compute. This reinforces that the GTX 550 Ti offers no performance advantage over current entry-level iGPUs.

Memory Subsystem

The GTX 550 Ti is equipped with 1024 MB of GDDR5 memory on a 192-bit bus, yielding a memory bandwidth of 98.50 GB/s. The memory clock runs at 1026 MHz, with an effective data rate of 4.1 Gbps. This bandwidth is sufficient for 720p gaming in older titles but becomes a bottleneck at 1080p or with high-resolution textures. The 192-bit bus is narrower than higher-tier Fermi cards, which limits how much data can be moved per clock cycle. For modern games with large texture sets, the 1 GB frame buffer fills quickly, causing stuttering or texture pop-in. The 98.50 GB/s bandwidth is roughly one-third of what mid-range cards from 2015 offered, so users should not expect smooth performance in any title that requires streaming high-resolution assets. The memory subsystem is the card’s most significant limitation after raw compute: even if the GPU cores could handle more work, the memory cannot feed them fast enough for demanding scenes. For 1440p or 4K, the card is not viable, as the bandwidth and capacity are far below recommended thresholds.

FAQ

Benchmark Performance

The sole benchmark available is Geekbench OpenCL, where the GTX 550 Ti scores 5731. This places it in the 32nd percentile of all GPUs, meaning roughly two-thirds of tested GPUs perform better. Against its nearest rivals, the card’s position is precarious. It edges out the Quadro K4000 by 0.1% (5731 vs 5723), which is within measurement error. It also beats the Iris Pro P6300 by 0.3% (5731 vs 5712), a lead so slim that it would vanish in real-world variance. However, it loses to the GTX 670MX by 0.2% (5731 vs 5742) and to the UHD P630 by 0.5% (5731 vs 5760). The pattern is clear: the GTX 550 Ti sits in a performance dead zone where it is statistically indistinguishable from several rivals, both older and newer. The 0.5% deficit against the UHD P630 is particularly telling, as that is an integrated GPU found in business laptops. The FP32 compute of 691.2 GFLOPS, combined with a texture rate of 28.80 GTexel/s and pixel rate of 7.200 GPixel/s, explains why the card cannot pull ahead of these rivals. The 1,170 million transistors on a 238 mm² die (4.9M transistors per mm²) represent a modest design even for 2011. The 192 shading units are too few to deliver meaningful parallel throughput, and the 24 ROPs limit fill-rate-bound workloads. The 1026 MHz memory clock, while effective at 4.1 Gbps, is hampered by the 192-bit bus, capping bandwidth at 98.50 GB/s. In any workload that stresses memory bandwidth or shader throughput, the card falls behind. The benchmark data shows that the GTX 550 Ti is a product of its time: it was competitive at launch, but today it only matches or slightly trails integrated graphics from Intel’s professional and consumer lines. The launch MSRP was 149 USD, but that historical figure does not reflect current performance value. For any modern task, the 32nd percentile ranking is the definitive verdict: this card belongs in a museum or a retro build, not in a daily driver.
