About NVIDIA GeForce GT 620 OEM
The NVIDIA GeForce GT 620 OEM is a 40 nm Fermi 2.0 part from the GeForce 600 generation, designed for basic desktop and HTPC duties rather than gaming or compute. It packs 48 shading units, 8 texture units, and 4 ROPs, paired with 512 MB of DDR3 memory on a 64-bit bus, yielding 14.37 GB/s of bandwidth. With a 30 W TDP, no auxiliary power connectors, and a single-slot 145 mm (5.7-inch) profile, it targets low-power, space-constrained systems. The database places it at the 50th percentile among all GPUs, indicating a middle-of-the-road standing in raw performance, though its memory capacity and bandwidth are severely limited by modern standards.
Who Should Consider It
The GT 620 OEM is not a card for gamers or content creators. Its 155.5 GFLOPS FP32 throughput and 1.620 GPixel/s pixel rate are sufficient only for 2D desktop rendering, video playback, and light office applications. The 512 MB memory buffer and 14.37 GB/s bandwidth mean that any 3D workload with textures larger than a few hundred megabytes will cause constant swapping to system memory, resulting in stutter and low frame rates. At 1080p, users should expect playable performance only in older titles from the early 2010s at reduced detail settings, and even then, the 4 ROPs will bottleneck fill-rate-heavy scenes. For 720p or lower resolutions, the card might handle simple eSports titles at minimum settings, but the lack of modern API features (no Vulkan) further limits compatibility with contemporary games.
Given its 30 W TDP and absence of power connectors, the GT 620 OEM is best suited for pre-built office PCs, point-of-sale terminals, or media center systems where a discrete GPU is needed solely to drive a display. Its 1x DVI, 1x HDMI 1.3a, and 1x VGA outputs cover legacy monitors and projectors. The 200 W suggested PSU is a conservative figure, meaning it can be dropped into almost any desktop with a spare PCIe x16 slot. Users who require hardware decoding of modern video codecs or any form of GPU-accelerated encoding will find the card lacking, as its Fermi 2.0 architecture predates most current media engines.
How It Compares
The fact pack provides no direct benchmark scores for rivals, so a head-to-head comparison cannot be made. However, the 50th percentile ranking across all GPUs in the database places this card exactly in the middle of the tracked performance distribution. This is a misleading position because the dataset includes many older and low-end parts; in practice, the GT 620 OEM sits far below any mainstream GPU released after 2015. Its 48 shading units and 4 ROPs are typical of a cut-down entry-level chip, and the 79 mm² die size with 292 million transistors reflects a modest silicon budget. Compared to its predecessor generation, the GeForce 500, this card inherits the same Fermi 2.0 architecture but with reduced specifications, and its successor, the GeForce 700 series, offers substantially higher core counts and memory bandwidth. Without concrete rival scores, the only quantitative anchor is the 50th percentile, which suggests that the card is neither the slowest nor the fastest in the database—a distinction that carries little weight given the wide range of performance represented.
Memory Subsystem
The GT 620 OEM ships with 512 MB of DDR3 memory on a 64-bit interface, running at an effective 1796 Mbps (898 MHz memory clock). This configuration yields a peak bandwidth of 14.37 GB/s—a figure that is dwarfed by even the most modest modern GPUs. The 64-bit bus width severely limits the amount of data that can be transferred per clock, and the low memory clock further constrains throughput. For 1080p gaming, textures and frame buffers will quickly exceed the 512 MB capacity, forcing the card to use system memory over the PCIe 2.0 x16 bus, which adds latency and reduces effective bandwidth. The 14.37 GB/s figure is sufficient for 2D framebuffer operations and simple video scaling, but any 3D scene with high-resolution textures will cause significant performance degradation. The lack of GDDR5 or wider bus means that memory bandwidth is the primary bottleneck, not the compute units. Users should treat the 512 MB as a hard limit for texture detail; modern games often require 2 GB or more, making this card unsuitable for anything beyond legacy titles.

Ray Tracing and Feature Set
The GT 620 OEM is built on the Fermi 2.0 architecture, which predates NVIDIA's RTX and tensor core implementations. The fact pack explicitly lists rtCores and tensorCores as null, confirming that hardware ray tracing and AI-accelerated features are absent. This is expected for a card from 2012, as ray tracing only became mainstream with the Turing generation. The card does support DirectX 12 (feature level 11_0) and OpenGL 4.6, allowing it to run modern APIs at a basic compatibility level, but without Vulkan support, it cannot leverage that cross-platform interface. The feature set is otherwise minimal: no hardware video encoder or decoder is mentioned, and the display outputs are limited to DVI, HDMI 1.3a (which caps 4K at 30 Hz), and VGA. The 30 W TDP and single-slot design make it a low-impact addition, but the lack of modern features means it cannot accelerate any current rendering effects, such as DLSS or variable rate shading. In summary, the GT 620 OEM is a legacy display adapter with no ray tracing, no tensor cores, and only basic API compatibility, making it suitable exclusively for 2D workloads and legacy software.
