About NVIDIA GeForce 845M

The NVIDIA GeForce 845M is a mobile graphics processor built on the Maxwell architecture, designed for laptops and portable devices. The benchmark data positions it at the 50th percentile among all GPUs, indicating a strictly mid-pack performer that offers a balanced, if unspectacular, level of capability for its generation. Its performance profile is defined by a modest set of specifications that prioritize efficiency over raw speed, making it a suitable choice for mainstream tasks rather than high-end gaming or professional workloads.

Benchmark Performance

The GeForce 845M’s performance, as indicated by its 50th percentile ranking, places it squarely in the middle of the GPU performance spectrum. This means that in a typical workload, it will outperform roughly half of all GPUs in the database while being outperformed by the other half. This is not a position of strength, but rather a clear indicator of a baseline-level product. The absolute performance is driven by its compute resources: 512 shading units operating at a fixed clock speed of 863 MHz for both base and boost. This configuration yields a peak FP32 performance of 883.7 GFLOPS, which is the primary metric for general-purpose and gaming compute.

This level of compute power translates into a texture fill rate of 27.62 GTexel/s and a pixel fill rate of 13.81 GPixel/s. These figures suggest that the 845M is capable of handling 1080p resolution in less demanding titles, but will struggle with the higher geometric complexity and shader loads of modern AAA games. The lack of any nearest rival data in the fact pack means we cannot provide specific percentage deltas against direct competitors. However, the 50th percentile score itself is the key comparative figure; it shows that this GPU is not a low-end part, but it is also far from being a performance leader. In practical terms, users should expect playable frame rates in esports and older titles, but will need to significantly lower graphical settings and resolution for more demanding games to maintain acceptable performance.

Ray Tracing and Feature Set

The GeForce 845M does not include dedicated ray tracing (RT) or tensor cores, as these are features of later architectures. Its feature set is rooted in the Maxwell generation, which relies on traditional rasterization techniques. The GPU does support a range of modern APIs, including DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. This API support is crucial for software compatibility, ensuring that the GPU can run games and applications that use these modern interfaces. However, the "11_0" designation within the DirectX 12 support indicates a feature level that is more aligned with DirectX 11, meaning it may not fully utilize all the advanced features of DirectX 12, such as certain types of bindless resources or advanced pipeline states.

The absence of RT and tensor cores means that the 845M cannot accelerate real-time ray tracing effects or AI-based features like DLSS (Deep Learning Super Sampling). This is a significant limitation for modern gaming, as these technologies are becoming increasingly common in new titles. The GPU's feature set is therefore best described as functional for its time, providing the necessary API hooks for broad compatibility but lacking the specialized hardware for state-of-the-art visual effects. The 28 nm process node from TSMC, with a die size of 148 mm² and 1,870 million transistors, further defines its capabilities, representing a mature manufacturing process that limits the efficiency and performance ceiling compared to newer, smaller node designs.

Who Should Consider It

Given its 50th percentile performance and the absence of modern features, the GeForce 845M is best suited for users with modest computing needs. The data suggests it is appropriate for light to moderate gaming at lower resolutions. In practical terms, it is a viable option for playing competitive titles like League of Legends, Counter-Strike: Global Offensive, or Dota 2 at 1080p with medium to high settings. These games are not particularly demanding on the GPU, and the 845M's 883.7 GFLOPS of compute power should be sufficient to maintain smooth frame rates.

For users who wish to play more graphically intensive games, the 845M will require significant compromises. The 13.81 GPixel/s pixel rate and 27.62 GTexel/s texture rate will become bottlenecks at 1080p with high-detail settings. Users would need to lower the resolution to 720p and reduce graphical presets to "Low" or "Medium" to achieve playable performance. The GPU is not designed for 4K gaming or for driving multiple high-resolution displays. It is also not suitable for content creation tasks like 3D rendering or heavy video editing, where the lack of tensor cores and higher FP32 performance would be a major disadvantage. Ultimately, this is a GPU for the casual gamer or general user who prioritizes a balanced system over peak performance.

Memory Subsystem

The memory subsystem of the GeForce 845M is a significant factor in its performance limitations. The GPU is equipped with 2 GB of DDR3 memory, which is a common but slower type of memory compared to the GDDR5 used in higher-performance parts of the same era. This is paired with a narrow 64-bit memory bus, which is a major constraint. The combination of DDR3 memory and a 64-bit bus results in a total memory bandwidth of just 16.02 GB/s. This figure is quite low by modern standards and represents a significant bottleneck for the GPU's processing power.

The low memory bandwidth means that the 845M will struggle to feed its 512 shading units with data quickly enough, particularly at higher resolutions and with high-resolution textures. For 1080p gaming, this can manifest as texture pop-in or stuttering in games with large, detailed environments. The 2 GB VRAM capacity is also a limiting factor; while sufficient for older games, it is inadequate for many modern titles that require 3 GB or more at high settings. At resolutions above 1080p, the 16.02 GB/s bandwidth becomes a severe bottleneck, causing a significant drop in frame rates. The effective memory clock speed of 2 Gbps, derived from a 1001 MHz base clock, further illustrates the memory's modest capabilities. This subsystem is adequate for basic tasks and older games but is a clear weak point when compared to the GPU's other specifications.

Power and Cooling

The GeForce 845M has a thermal design power (TDP) of 45 W, classifying it as a low-power component. This is a crucial specification for mobile devices, as it directly impacts the laptop's cooling requirements and battery life. The low TDP means that the GPU can be cooled by a simple, quiet cooling solution, and it generates a relatively small amount of heat. This makes it an excellent fit for thin and light laptops where space and thermal headroom are at a premium.

The fact pack lists the slot width as "IGP" (Integrated Graphics Processor), which indicates that the GPU is typically soldered directly onto the motherboard rather than being a removable MXM module. This design is common for low-power mobile GPUs and means that it is not user-upgradeable. Furthermore, the fact pack does not list any power connectors or a suggested PSU (Power Supply Unit), which is expected for a mobile part. The power is drawn directly from the motherboard's power delivery system. The lack of external power connectors and a suggested PSU recommendation underscores that this GPU is not intended for desktop use or for systems with high power demands. The 45 W TDP is the primary figure to consider for system design, ensuring that the laptop's overall power budget remains within reasonable limits.

How It Compares

The fact pack does not include a list of nearest rivals with specific performance scores and delta percentages. Therefore, a direct quantitative comparison against named competitors is not possible based on the provided data. The only available benchmark context is the 50th percentile ranking, which serves as a general indicator of its standing in the market.

Without specific rival data, we can infer its position from its specifications. Its 512 shading units and 883.7 GFLOPS of FP32 performance place it in a category that is a step above entry-level parts but significantly below mainstream and high-performance GPUs of its generation. Its predecessor, the GeForce 700M, would have had similar or lower performance numbers, while its successor, the GeForce 900M, likely offered a substantial increase in both performance and efficiency due to architectural improvements. The 845M's position is therefore that of a dependable, mid-range mobile solution that offers a balanced feature set for its time, but it is not a standout performer in any single metric. The lack of specific rival data means that any further comparison would rely on speculation, which is outside the scope of this analysis.
