NVIDIA GeForce GTX 745 OEM

The NVIDIA GeForce GTX 745 OEM is an end-of-life graphics card built on the Maxwell architecture, using the GM107 chip fabricated on TSMC's 28 nm process. It holds the 50th percentile rank among all GPUs in the benchmark database, placing it exactly at the median of the performance distribution. With 1,870 million transistors on a 148 mm² die, this card represents a specific entry point in the GeForce 700 series, succeeding the GeForce 600 generation and preceding the GeForce 900 series. The transistor density of 12.6M per mm² reflects the 28 nm manufacturing node. As an OEM part, it was designed for pre-built systems, and its production status is now end-of-life.

Memory Subsystem

The GTX 745 OEM ships with 4 GB of DDR3 memory on a 128-bit bus, yielding a memory bandwidth of 28.80 GB/s. The memory clock runs at 900 MHz, translating to 1800 Mbps effective. This configuration is a study in trade-offs. The 4 GB capacity is generous for the card's class, allowing large texture sets to reside locally. However, the 128-bit bus width and DDR3 type severely constrain bandwidth. At high resolutions, the fill rate demand outstrips what 28.80 GB/s can supply, causing the memory subsystem to become the primary bottleneck. The 16 ROPs and 24 TMUs must be fed through this narrow pipe, and the data shows that the bandwidth figure is the most limiting specification for demanding workloads. For standard gaming resolutions, the 4 GB capacity is rarely exceeded, but the bandwidth becomes the limiting factor as resolution scales upward. The pixel rate of 16.53 GPixel/s and texture rate of 24.79 GTexel/s are directly tied to how quickly the memory can deliver data to the shading units. In essence, the memory subsystem is the Achilles' heel of this card, balancing a large frame buffer against a narrow data path.

Ray Tracing and Feature Set

The Maxwell architecture in this card provides no dedicated ray tracing cores and no tensor cores, as the fact pack lists both as null. This means hardware-accelerated ray tracing and AI-based features are entirely absent. Instead, the card relies on its 384 shading units for all compute. API support includes DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The DirectX 12 support is at the 11_0 feature level, indicating that while the card can run DirectX 12 titles, it does not expose the full feature set of higher-tier implementations. For users seeking modern rendering techniques, the lack of RT and tensor cores is a definitive limitation. The shading units are the sole computational resource, and their count of 384 is modest. The card's feature set is thus anchored to traditional rasterization, with no path to ray-traced effects or DLSS-style upscaling. The OpenGL 4.6 and Vulkan 1.4 support ensure broad compatibility with current software, but the underlying hardware lacks the specialized units that define contemporary GPUs.

How It Compares

The fact pack provides no nearest rival data for the GTX 745 OEM, so direct delta comparisons against specific competitors are unavailable. The benchmark percentile of 50 places this card at the exact median of all GPUs in the database, meaning it outperforms half of the field and trails the other half. Its position in the product stack is clear: it succeeds the GeForce 600 series and precedes the GeForce 900 series. This places it in a transitional era, where the Maxwell architecture brought efficiency improvements over its predecessor, but the card itself is positioned as an OEM-focused part, indicated by its 'OEM' designation and end-of-life status. The 50th percentile rank is a useful anchor; it suggests that in a typical distribution of GPU performance, this card sits squarely in the middle. Without rival names, the analysis must rely on absolute metrics and the percentile. The die size of 148 mm² and transistor count of 1,870 million place it in a specific physical class, but these do not translate directly to performance without context. The card's release date of 2014-02-17 places it in the early Maxwell era.

FAQ

Q: What is the memory size and type on the GTX 745 OEM?

A: It has 4 GB of DDR3 memory on a 128-bit bus, providing a bandwidth of 28.80 GB/s. The memory clock is 900 MHz, or 1800 Mbps effective.

Benchmark Performance

The benchmark data for the GTX 745 OEM shows a percentile rank of 50 among all GPUs, which is a precise median placement. The absolute performance metrics are 793.3 GFLOPS of FP32 compute, a pixel rate of 16.53 GPixel/s, and a texture rate of 24.79 GTexel/s. These figures indicate a card that is capable of basic 3D rendering but lacks the throughput for demanding workloads. Because the nearestRivals array is empty, no percentage deltas can be computed against specific competitors. The absence of rival data means that the percentile rank is the only comparative benchmark available. A 50th percentile score suggests that in a typical database of GPUs, this card sits squarely in the middle, neither a low-end placeholder nor a high-performance part. The compute density, at 12.6M transistors per mm², reflects the 28 nm process node, but the raw GFLOPS figure is modest by modern standards. The 384 shading units, 24 TMUs, and 16 ROPs work together to produce the stated pixel and texture rates. The FP32 throughput of 793.3 GFLOPS is the headline compute number, and it aligns with the card's position in the performance hierarchy. Without rival deltas, the percentile of 50 is the definitive comparative statement.

Power and Cooling

The GTX 745 OEM is a low-power part with a TDP of 55 W. It draws power solely from the PCIe slot, as it has no external power connectors. A 250 W power supply is suggested for a system using this card. The card occupies a single slot and has a length of 145 mm (5.7 inches), making it suitable for compact OEM chassis. The absence of power connectors simplifies installation, and the low TDP means that cooling requirements are minimal, though the fact pack does not specify a cooler design. The single-slot form factor and short length are notable for space-constrained systems. The bus interface is PCIe 3.0 x16, which is compatible with most motherboards from its era. The display outputs include 1x DVI, 1x HDMI 1.4a, and 1x VGA, covering legacy and modern displays. The 250 W PSU recommendation is modest, ensuring that even low-end power supplies can handle this card.

Who Should Consider It

Given its 50th percentile rank and memory subsystem characteristics, the GTX 745 OEM is suited for users running lower resolutions and moderate settings. The 4 GB DDR3 memory provides ample capacity, but the 28.80 GB/s bandwidth and 128-bit bus limit high-resolution performance. The card's FP32 throughput of 793.3 GFLOPS and pixel rate of 16.53 GPixel/s indicate it can handle older or less demanding titles. It is an end-of-life product, so it is primarily relevant for legacy systems or as a drop-in replacement for OEM machines. Users seeking modern features like ray tracing will find none here, as the card lacks RT and tensor cores. For a system that requires a low-power, single-slot card with no auxiliary power, this GPU fits a narrow niche. The release date of 2014-02-17 places it in the early Maxwell era, and its 50th percentile ranking reflects its historical mid-pack standing. The suggested 250 W PSU and 55 W TDP make it an easy upgrade for older pre-built desktops. However, for any modern high-resolution gaming, the bandwidth bottleneck will be apparent.
