NVIDIANVIDIA GeForce 620M Specifications
GPU Core
Shader units and compute resources
The NVIDIA GeForce 620M GPU core specifications define its raw processing power for graphics and compute workloads. Shading units (also called CUDA cores, stream processors, or execution units depending on manufacturer) handle the parallel calculations required for rendering. TMUs (Texture Mapping Units) process texture data, while ROPs (Render Output Units) handle final pixel output. Higher shader counts generally translate to better GPU benchmark performance, especially in demanding games and 3D applications.
620M Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce 620M's performance in GPU benchmarks and real-world gaming. The base clock represents the minimum guaranteed frequency, while the boost clock indicates peak performance under optimal thermal conditions. Memory clock speed affects texture loading and frame buffer operations. The GeForce 620M by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce 620M Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce 620M's memory capacity determines how well it handles high-resolution textures and multiple displays. Memory bandwidth, measured in GB/s, affects how quickly data moves between the GPU and VRAM. Higher bandwidth improves performance in memory-intensive scenarios like 4K gaming. The memory bus width and type (GDDR6, GDDR6X, HBM) significantly influence overall GPU benchmark scores.
GeForce 620M by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the 620M, reducing the need to fetch data from slower VRAM. L1 and L2 caches store frequently accessed data close to the compute units. AMD's Infinity Cache (L3) dramatically increases effective bandwidth, improving GPU benchmark performance without requiring wider memory buses. Larger cache sizes help maintain high frame rates in memory-bound scenarios and reduce power consumption by minimizing VRAM accesses.
620M Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the NVIDIA GeForce 620M against other graphics cards. FP32 (single-precision) performance, measured in TFLOPS, indicates compute capability for gaming and general GPU workloads. FP64 (double-precision) matters for scientific computing. Pixel and texture fill rates determine how quickly the GPU can render complex scenes. While real-world GPU benchmark results depend on many factors, these specifications help predict relative performance levels.

Manufacturing and design details
The NVIDIA GeForce 620M is built on NVIDIA's Fermi 2.0 architecture, which defines how the GPU processes graphics and compute workloads. The manufacturing process node affects power efficiency, thermal characteristics, and maximum clock speeds. Smaller process nodes pack more transistors into the same die area, enabling higher performance per watt. Understanding the architecture helps predict how the 620M will perform in GPU benchmarks compared to previous generations.
Power & Thermal
TDP and power requirements
Power specifications for the NVIDIA GeForce 620M determine PSU requirements and thermal management needs. TDP (Thermal Design Power) indicates the heat output under typical loads, guiding cooler selection. Power connector requirements ensure adequate power delivery for stable operation during demanding GPU benchmarks. The suggested PSU wattage accounts for the entire system, not just the graphics card. Efficient power delivery enables the GeForce 620M to maintain boost clocks without throttling.
GeForce 620M by NVIDIA Physical & Connectivity
Dimensions and outputs
Physical dimensions of the NVIDIA GeForce 620M are critical for case compatibility. Card length, height, and slot width determine whether it fits in your chassis.

About NVIDIA GeForce 620M
The NVIDIA GeForce 620M is an end-of-life mobile graphics solution built on the Fermi 2.0 architecture. Fabricated by TSMC on a 28 nm process, the chip packs 585 million transistors into a 116 mm² die, yielding a transistor density of 5.0M / mm². The data shows a 50th percentile placement among all GPUs in the database, yet the average benchmark score is recorded as 0, indicating that no direct performance measurements exist for this part. This analysis relies on the theoretical specifications and architectural details provided in the fact pack. The GPU is part of the GeForce 600M generation, succeeding the GeForce 500M and preceding the GeForce 700M. Its production status is end-of-life, and it was released on 2012-03-21.
Benchmark Performance
The average benchmark score for the GeForce 620M is 0, and the nearestRivals list is empty. This means the database holds no recorded performance tests for this GPU. The 50th percentile is a positional rank, but without a score, it's a placeholder. The theoretical peak FP32 throughput is 240.0 GFLOPS, which comes from 96 shading units. The pixel rate is 2.500 GPixel/s and texture rate is 10.00 GTexel/s. These are the raw numbers. Given the architecture (Fermi 2.0) and the low power envelope, the data suggests a very low-end part. The lack of benchmarks means we cannot state deltas against rivals, but the theoretical numbers place it well below any modern discrete GPU. The 50th percentile likely reflects its historical position among all GPUs ever released, but the zero score is a red flag for data completeness. The 240.0 GFLOPS figure is modest, and the 2.500 GPixel/s pixel rate is equally restrained. When combined with the 14.40 GB/s memory bandwidth, the data implies that the GPU is heavily constrained by its memory subsystem, which will be explored in the next section. The 10.00 GTexel/s texture rate, while not impressive by modern standards, is consistent with a chip designed for entry-level laptops in 2012. Without recorded benchmarks, the percentile rank of 50 must be interpreted cautiously; it suggests the GPU sits in the middle of the database's historical distribution, but the zero score means no empirical data supports that placement.
Memory Subsystem
The GeForce 620M is equipped with 1024 MB of DDR3 memory on a 64-bit bus. The memory clock is 900 MHz, translating to 1800 Mbps effective, which yields a total bandwidth of 14.40 GB/s. This is a very narrow and slow memory interface. For high resolutions, this bandwidth is a severe bottleneck. The 64-bit bus width halves the data path compared to typical 128-bit solutions, and the 14.40 GB/s is far below what modern games require. The 1024 MB capacity is also minimal. The data implies that this GPU is only suitable for low resolutions and older titles, as the memory subsystem cannot feed the shading units fast enough for demanding workloads. The 14.40 GB/s bandwidth is a hard ceiling for texture fetches and framebuffer writes. Even the 10.00 GTexel/s texture rate would require significant bandwidth to sustain, and the 2.500 GPixel/s pixel rate is low enough that the memory might keep up only at low resolutions. The 64-bit bus width is a clear indicator of its entry-level positioning. Users attempting to run modern games at high resolutions will likely experience severe stuttering and low frame rates, though the data does not provide specific frame rate numbers. The 1024 MB capacity, while adequate for the era's operating systems, is insufficient for modern texture-heavy workloads.
Power and Cooling
The TDP is rated at 15 W, which is extremely low. The slot width is listed as "IGP" (Integrated Graphics Processor), meaning it is not a discrete card. It has no power connectors, and the display outputs are "Portable Device Dependent". The bus interface is PCIe 2.0 x16. Because it's an IGP, it relies on the laptop's cooling solution. The 15 W TDP means a simple heat spreader or the system's existing cooling is sufficient. The data does not list a suggested PSU, which is consistent with an integrated part that draws power from the motherboard. The lack of power connectors reinforces that this is a low-power, integrated solution. The 15 W figure is a key differentiator; it is low enough to be passively cooled in many thin-and-light laptops. The PCIe 2.0 x16 interface is standard for the era, though the integrated nature means it may share memory with the system in some configurations, though the fact pack does not specify this. The absence of a suggested PSU is notable, as discrete GPUs typically require a recommended wattage; here, the integrated design eliminates that concern entirely. The low TDP also means the GPU generates minimal heat, which is a boon for battery life in portable devices.
How It Compares
The FACT PACK's nearestRivals array is empty, so there are no direct rival scores to compare against. The data provides no deltaPct values or rival names. This absence is notable; it means the database has not yet populated comparative benchmarks for this model. Without rival data, we cannot quantify performance gaps. However, the GPU's generation is "GeForce 600M", with a predecessor of "GeForce 500M" and a successor of "GeForce 700M". This places it chronologically between those two generations. The 50th percentile rank is a global metric, but without a baseline score, it's not meaningful for direct comparison. The theoretical specs (240 GFLOPS, 14.40 GB/s) suggest it is a low-end part, but without rival data, we cannot quantify the gap. The empty rival list is a notable absence, indicating that the database has not yet populated comparative benchmarks for this model. In the absence of rivals, the analysis must rely on the absolute specifications and the percentile rank. The 50th percentile, when paired with a zero average score, suggests that the GPU is positioned in the middle of the historical database purely by its presence, not by measured performance. This is a unique situation where the lack of data itself becomes a data point, highlighting the challenges of evaluating legacy hardware.
Who Should Consider It
Given the specifications, the GeForce 620M is suited for basic computing tasks and very light gaming. The 1024 MB memory and 14.40 GB/s bandwidth limit it to low resolutions and low graphical settings. The 240.0 GFLOPS FP32 performance is enough for older titles or esports games with minimal requirements. The 15 W TDP makes it ideal for ultra-portable laptops where battery life is prioritized over performance. Users should not expect to run modern AAA games at high settings. The data suggests it is a legacy part, now end-of-life, so it is only relevant for users with older laptops or those seeking a basic display output solution. The 2.500 GPixel/s pixel rate and 10.00 GTexel/s texture rate are sufficient for 2D desktop workloads and video playback, but 3D gaming will be limited to titles from the early 2010s or earlier. The lack of a suggested PSU reinforces its integrated nature, so users do not need to worry about power supply upgrades. The 50th percentile rank, despite the zero score, suggests it was a mainstream part at its time, but modern software demands have far outpaced its capabilities. For users with such a laptop, the best use case is office productivity, web browsing, and media consumption, not gaming.

Ray Tracing and Feature Set
The FACT PACK lists no RT cores and no tensor cores, meaning the GeForce 620M does not support hardware ray tracing or AI-accelerated tensor operations. The API support includes DirectX 12 (11_0) and OpenGL 4.6, but Vulkan support is listed as null. The shading units number 96, with 16 TMUs and 8 ROPs. The FP32 throughput is 240.0 GFLOPS. The display outputs are "Portable Device Dependent", meaning they vary by laptop. The absence of RT and tensor cores is expected for a Fermi 2.0 part from 2012, as those technologies were introduced much later. The feature set is therefore limited to traditional rasterization and compute. The DirectX 12 support at the 11_0 feature level means it can run DirectX 12 applications, but only with the feature set of DirectX 11. This is a compatibility feature rather than a performance one. OpenGL 4.6 support is present, which is useful for legacy applications. The lack of Vulkan support is a notable omission, as Vulkan is a modern low-level API. The 96 shading units and 16 TMUs are the core compute resources, and the 8 ROPs handle pixel output. The 240.0 GFLOPS is the peak FP32 performance, which is the primary metric for general compute workloads. Without tensor cores, any machine learning or AI-accelerated features are entirely absent, making this GPU unsuitable for modern compute tasks beyond basic shader work.
