About NVIDIA GeForce GT 630 Rev. 2 PCIe x8
The NVIDIA GeForce GT 630 Rev. 2 PCIe x8 is a Kepler 2.0 architecture entry-level graphics card built on TSMC's 28 nm process. It features the GK208 chip with 1,020 million transistors on an 87 mm² die, and is positioned at the 50th percentile against all GPUs in the database. The card's production status is end-of-life, with a release date of May 28, 2013, and it serves as a bridge between the GeForce 500 and GeForce 700 generations.
Benchmark Performance
The GT 630 Rev. 2 presents a unique case in the benchmark database, as its average benchmark score is recorded as 0, and the nearestRivals field is empty. This absence of comparative data points means the card's performance must be assessed through its theoretical compute specifications rather than direct empirical comparisons. The FP32 performance is rated at 692.7 GFLOPS, which is derived from 384 shading units operating at the card's fixed clock configuration. The pixel rate stands at 7.216 GPixel/s, while the texture rate reaches 28.86 GTexel/s.
Without nearestRivals data, the percentile rank of 50 provides the only positional context, indicating the card sits exactly at the median of all GPUs tracked in the database. This suggests it occupies a middle ground in the overall performance distribution, though this percentile likely reflects its historical ubiquity as a basic OEM and entry-level card rather than raw computational prowess. The texture rate of 28.86 GTexel/s, when divided across the 32 TMUs, indicates a modest per-unit throughput that aligns with the card's intended role for light desktop usage and legacy applications.
The shading unit count of 384 is notable for a card with such a low power envelope. The FP32 figure of 692.7 GFLOPS places it well below any modern gaming-oriented GPU, but the architecture's efficiency at 28 nm allows for this throughput within a 25 W thermal design power. The ROP count of 8 limits fill-rate intensive operations, which is why the pixel rate of 7.216 GPixel/s remains constrained. Benchmark results indicate this card was never designed for competitive gaming, but rather for basic display output and hardware acceleration of video playback.
Ray Tracing and Feature Set
The GT 630 Rev. 2 does not include dedicated ray tracing cores or tensor cores, as these features were not part of the Kepler 2.0 architecture. The card's API support includes DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The DirectX 12 support is feature level 11_0, which means it can run DirectX 12 applications but without the advanced features like bindless resources or conservative rasterization that higher feature levels provide. This limitation is expected given the card's 2013 origins.
OpenGL 4.6 support is comprehensive for the era, allowing compatibility with a wide range of professional and creative applications that rely on this API. The Vulkan 1.2.175 support is surprisingly modern for a card of this vintage, enabling access to cross-platform low-overhead graphics in supported titles. However, the lack of tensor cores means no AI-accelerated features such as DLSS are available, and the absence of RT cores precludes any hardware-accelerated ray tracing. Any ray tracing effects would have to be software-based, which given the FP32 throughput of 692.7 GFLOPS, would result in extremely poor performance.
The display outputs include 1x DVI, 1x HDMI 1.4a, and 1x VGA, which covers legacy and modern display connections. The HDMI 1.4a standard supports 1080p output at standard refresh rates but lacks the bandwidth for 4K at high refresh rates or HDR content. The VGA output confirms the card's target market of older monitors and office environments where digital connections may not be available. The card's single-slot design and lack of any power connectors further emphasize its low-profile, low-consumption positioning.
Power and Cooling
The GT 630 Rev. 2 has a thermal design power of just 25 W, making it one of the most power-efficient cards in the database. This low TDP means the card requires no external power connectors, drawing all its power from the PCIe slot itself. The suggested PSU rating is 200 W, which is an extremely modest requirement that allows the card to be installed in nearly any system, including pre-built office desktops with minimal power supplies.
The single-slot cooling solution is sufficient for the 25 W thermal load, as the GK208 chip's 28 nm process keeps heat generation minimal. The card measures 115 mm or 4.5 inches in length, making it compatible with small form factor cases where space is at a premium. The absence of power connectors simplifies installation, as no additional cabling is required. The power delivery is entirely through the PCIe 2.0 x8 bus interface, which provides both data connectivity and electrical power within its specified limits.
The 200 W suggested PSU figure is a recommendation, not a hard requirement, and reflects the total system power draw including the CPU and other components. This makes the GT 630 Rev. 2 an ideal drop-in replacement for systems with failing integrated graphics or for basic troubleshooting. The low power consumption also means passive cooling solutions could theoretically be used, though the stock cooler is adequate for all operational scenarios. The combination of 25 W TDP and 200 W PSU recommendation creates a wide margin of safety for any system configuration.

Who Should Consider It
The GT 630 Rev. 2 is suitable for users who require basic display output without any gaming aspirations. The FP32 performance of 692.7 GFLOPS is sufficient for 2D desktop applications, office productivity, and video playback at 1080p resolutions. The 2 GB memory capacity allows for multiple displays to be driven simultaneously, though the 64-bit bus width and 14.40 GB/s bandwidth will struggle with any memory-intensive workloads. Users with older systems lacking integrated graphics or those needing a temporary display adapter will find this card adequate.
For gaming, the card is not recommended for any modern titles, even at low settings. The pixel rate of 7.216 GPixel/s and texture rate of 28.86 GTexel/s are simply too low for 3D rendering beyond very old or very light games. The 384 shading units, while numerous for the power class, cannot compensate for the memory bandwidth bottleneck. The card's 50th percentile ranking suggests it outperforms half of all GPUs in the database, but this is likely due to the inclusion of many weaker integrated and legacy discrete solutions. At 720p or lower resolutions, some pre-2010 games might run at playable frame rates, but the experience would be severely compromised.
The card is best suited for home theater PCs (HTPCs) where its 25 W TDP ensures minimal heat and noise, and its HDMI 1.4a output connects easily to televisions. The VGA output also makes it useful for connecting to older projectors or monitors in conference rooms. The single-slot design and short length of 115 mm allow installation in compact chassis where larger cards would not fit. Given its end-of-life status, the card is only relevant for legacy system maintenance or very basic computing needs.
Memory Subsystem
The memory subsystem of the GT 630 Rev. 2 consists of 2 GB of DDR3 memory connected via a 64-bit bus interface. The memory clock operates at 900 MHz, translating to an effective data rate of 1800 Mbps. This configuration yields a total memory bandwidth of 14.40 GB/s, which is a significant bottleneck for the card's overall performance. The 64-bit bus width is half of what was common in mainstream cards of that era, limiting the amount of data that can be transferred between the GPU and memory in a given clock cycle.
The 2 GB capacity is generous for the card's performance class, allowing large textures to be loaded into memory, but the bandwidth limitation means those textures cannot be accessed quickly enough for smooth rendering in 3D applications. For high-resolution scenarios, such as 1440p or 4K output, the memory subsystem becomes the primary constraint. While the 2 GB capacity can hold framebuffers for these resolutions, the 14.40 GB/s bandwidth is insufficient to update the screen and process textures simultaneously without severe stuttering.
The DDR3 memory type is also slower than the GDDR5 used in higher-performance cards of the same generation, further compounding the bandwidth deficit. The pixel rate of 7.216 GPixel/s, when combined with the memory bandwidth, indicates that the card can only handle simple fill-rate tasks effectively. For 1080p video playback, the memory subsystem is adequate, as video decoding does not require the same memory access patterns as 3D rendering. The 64-bit bus is also reflected in the card's overall power efficiency, as narrower buses consume less power, contributing to the 25 W TDP figure.
