About NVIDIA GeForce GT 545 OEM
Power and Cooling
The NVIDIA GeForce GT 545 OEM carries a TDP of 105 W, positioning it as a modest power draw within the Fermi 2.0 generation. This figure dictates a moderate thermal design, which is reflected in the card's dual-slot cooler. The dual-slot footprint suggests a substantial heatsink and fan assembly, capable of dissipating the heat generated by the 1,170 million transistors packed into the 238 mm² die. The 40 nm process node from TSMC is the underlying manufacturing technology, and the transistor density of 4.9M / mm² indicates a relatively relaxed packing compared to denser modern designs, which helps keep thermals manageable at this power level.
Power delivery requires a single 6-pin PCIe power connector. This is a standard requirement for cards in this class, and the system power supply recommendation is set at 300 W. This 300 W figure is a guideline for the entire platform, not just the graphics card, meaning users need a PSU that can handle the card's 105 W draw alongside the rest of the system components. The reliance on a 6-pin connector, rather than a more demanding 8-pin or dual-connector setup, underscores the card's relatively low power appetite. The bus interface is PCIe 2.0 x16, which is compatible with a wide range of motherboards from the era, though users with newer systems should verify backward compatibility. The card's physical length of 210 mm (8.3 inches) is a key clearance consideration for smaller cases; it is not a compact low-profile design, so chassis space must be planned accordingly.
Ray Tracing and Feature Set
The GT 545 OEM is built on the Fermi 2.0 architecture and does not include dedicated RT cores or tensor cores. This is a fundamental distinction from modern GeForce offerings; the hardware is entirely devoid of ray tracing acceleration and AI-driven tensor processing capabilities. The absence of these units means that any ray-traced workloads, if attempted, would fall back to compute shaders on the traditional shader array, resulting in performance that is not viable for real-time ray tracing in contemporary titles. Similarly, the lack of tensor cores precludes any DLSS-style upscaling or AI-based features.
The feature set is anchored by its API support. The card supports DirectX 12 with a feature level of 11_0. This is a crucial distinction: while it can run DirectX 12 applications, the 11_0 feature level means it cannot access the full DirectX 12 feature set, such as mesh shaders or variable rate shading, which require higher feature levels. OpenGL 4.6 support is also present, ensuring compatibility with a broad range of professional and legacy applications that rely on this API. The shading unit count stands at 144, with 24 texture mapping units (TMUs) and 16 render output units (ROPs). These resources drive the pixel rate of 5.226 GPixel/s and texture rate of 20.90 GTexel/s. The FP32 compute performance is rated at 501.4 GFLOPS, a figure that defines the card's general-purpose processing throughput. The memory subsystem is a 1024 MB GDDR5 buffer on a 128-bit bus, running at an effective 4 Gbps, which yields a bandwidth of 64.00 GB/s. This bandwidth is a critical bottleneck for higher resolutions and texture-heavy scenes, given the relatively narrow bus.
Who Should Consider It
Given its benchmark position in the 50th percentile of all GPUs and an average benchmark score of zero, the GT 545 OEM is best suited for a very specific niche. The data suggests this is not a card for modern high-fidelity gaming. The 1024 MB memory capacity and 64.00 GB/s bandwidth are insufficient for 1080p gaming at high settings in contemporary titles, which routinely exceed 2 GB of VRAM usage. The 501.4 GFLOPS compute throughput and 5.226 GPixel/s pixel rate further limit its capability to push high resolutions or high refresh rates.
The card is more appropriately targeted at legacy gaming, specifically titles from its 2011 release era (predecessor: GeForce 400, successor: GeForce 600). For games from that period, the 144 shading units and 20.90 GTexel/s texture rate can handle 720p or 1080p at medium to low settings. It is also a viable candidate for a secondary display output or a basic HTPC build, given its dual DVI and mini-HDMI 1.3a outputs. The 50th percentile ranking indicates it sits exactly in the middle of the performance curve historically, meaning it was an entry-level to mid-range card when released, but that position has been eroded by time. Users considering this card for modern workloads should re-evaluate; the DirectX 12 (11_0) support is a compatibility checkbox, not a performance guarantee. For productivity tasks that are not GPU-intensive, such as 2D desktop work or video playback, the card is perfectly adequate, but any 3D rendering or gaming beyond casual titles will expose its limitations.

How It Compares
The FACT PACK lists no nearest rivals for the GT 545 OEM, so a direct quantitative comparison against specific competing models using deltaPct scores is not possible from the available data. The benchmark data shows an average benchmark score of zero and a percentile rank of 50, meaning it sits at the median of all GPUs in the database. This indicates that there are many faster cards and many slower cards, but without named rivals, a positional analysis must rely on this percentile. The performance is defined by its 501.4 GFLOPS FP32 throughput and 64.00 GB/s bandwidth, which are the metrics by which it would be judged against any other card. Since no rival names or scores are provided, any claim of being "ahead of" or "behind" a specific competitor cannot be substantiated. The user looking at this card should interpret the 50th percentile as a historical marker: it was an average performer at its time of release, and that position has not improved with age. The lack of competitor data in the pack means the benchmark database does not currently have sufficient comparative entries to establish a deltaPct relationship with any other GPU.
