The NVIDIA GeForce 840A 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.
840A Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce 840A'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 840A by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce 840A Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce 840A'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.

About NVIDIA GeForce 840A
The NVIDIA GeForce 840A is a mobile-integrated graphics processor built on the Maxwell architecture, targeting the entry-level segment of the GeForce 800A generation. It is a 28 nm chip fabricated by TSMC, containing 1,020 million transistors on a die size of 77 mm², which yields a transistor density of 13.2M per mm². The GPU operates with a base clock of 1029 MHz and a boost clock of 1124 MHz, and its production status is marked as end-of-life. This analysis draws exclusively from the provided specification data, interpreting how this part positions itself against the broader landscape of GPU performance.
Power and Cooling — TDP, PSU recommendation, connector requirements
The thermal design power for the GeForce 840A is rated at 33 W. This low figure classifies the chip as a highly efficient part, suitable for compact and thermally constrained environments. Given that the slot width is listed as "IGP" — integrated graphics platform — the GPU is designed to be embedded directly onto a motherboard or portable device module, rather than installed as a discrete expansion card. This form factor inherently limits the need for aftermarket cooling solutions, as the thermal envelope is modest enough for passive or low-profile active cooling in a laptop or small-form-factor chassis.
The power connector requirement is listed as "None". The 840A draws all its operating power from the motherboard's PCIe slot or the system's dedicated power delivery for integrated parts. This eliminates the need for any supplementary power cables, simplifying installation in systems where space and cabling are at a premium. The absence of a suggested PSU rating in the data further reinforces that this is not a component requiring an upgraded power supply; a standard system PSU designed for the host platform will suffice. The bus interface is PCIe 3.0 x8, which provides adequate bandwidth for the GPU's memory subsystem and compute capabilities, though the x8 lane configuration reflects its entry-level positioning.
Ray Tracing and Feature Set — RT/tensor cores, API support from facts
The GeForce 840A does not include dedicated ray tracing cores or tensor cores, as these fields are reported as null in the specification. This indicates that the hardware is not designed for real-time ray tracing workloads or AI-accelerated tensor operations, which are features found in more modern and higher-tier architectures. The absence of these units means that any ray-traced effects would need to be handled through software or compute shaders, if at all, which would be impractical given the GPU's compute throughput.
The API support for the 840A includes DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4. The DirectX 12 entry, noted as "12 (11_0)", is a critical distinction: it implies the hardware is feature-compatible with the DirectX 11_0 feature level, not the full DirectX 12 feature set. This limits the GPU's ability to leverage advanced DirectX 12 features such as bindless resources or enhanced barrier semantics. OpenGL 4.6 and Vulkan 1.4 support provide modern graphics API access, which can be leveraged for cross-platform compatibility, but the underlying hardware limitations will cap the performance and feature utilization. The display outputs are listed as "Portable Device Dependent", meaning the physical connectors and supported resolutions are dictated by the specific laptop or mobile device the GPU is integrated into.
How It Compares — position vs each nearest rival
The FACT PACK does not list any nearest rivals for the GeForce 840A, as the `nearestRivals` array is empty. Consequently, there are no direct comparison points, score deltas, or percentile rankings against specific competitor models to analyze. The `percentileVsAllGpus` field indicates a value of 50, which places the GPU at the midpoint of all GPUs tracked in the benchmark database. This suggests that while it is not a high-performance part, it is not at the very bottom of the performance spectrum either, representing a baseline level of capability relative to the entire catalog of GPUs.
With no rival names provided, the analysis must rely on the absolute performance metrics and the percentile positioning. The 50th percentile is a neutral standing, implying that half of the GPUs are faster and half are slower. This is consistent with an entry-level mobile part that is intended for basic computing tasks, light multimedia consumption, and undemanding legacy games, rather than for competitive or high-fidelity gaming. The absence of rival data precludes any direct speed comparisons, but the percentile figure serves as a global anchor for its relative standing.

Benchmark Performance — analyze scores vs rivals with exact % deltas
The benchmark data for the GeForce 840A shows an `avgBenchmarkScore` of 0, and the `benchmarks` array is empty. This absence of specific benchmark scores means there are no direct performance metrics from standardized tests to analyze. The only quantitative performance indicator available is the `percentileVsAllGpus` value of 50, which signals a median performance position across the entire GPU database. This percentile is derived from the comparative performance of all GPUs tracked, but without the underlying scores or rival deltas, a precise interpretation of its speed is limited to this relative standing.
The compute capabilities provide a theoretical framework for understanding its performance. The FP32 throughput is 863.2 GFLOPS, which is the peak single-precision floating-point performance. The pixel rate of 8.992 GPixel/s and texture rate of 17.98 GTexel/s are modest figures that align with its entry-level classification. When compared to the 50th percentile standing, these numbers suggest that the GPU delivers roughly half the performance of the median GPU in the database, but the lack of rival data prevents any exact percentage deltas from being calculated. The data indicates a part that is suitable for low-resolution, low-detail gaming or basic graphical acceleration, but definitive performance ratios against specific competitors cannot be established from the provided facts.
Who Should Consider It — resolution/settings-based recommendations grounded in the scores
Based on the performance metrics, the GeForce 840A is best suited for users operating at low resolutions, such as 720p or lower, with minimal graphical settings. The FP32 throughput of 863.2 GFLOPS and the memory bandwidth of 16.02 GB/s are the limiting factors; these figures suggest that modern 3D games with high-resolution textures or complex shaders would likely exceed the GPU's capacity. The data implies that the 840A is appropriate for older titles, 2D indie games, or esports titles configured to the lowest settings to achieve playable frame rates. The 2 GB DDR3 memory on a 64-bit bus is sufficient for basic framebuffer needs but will struggle with high-resolution assets or large scene complexity.
Users who rely on the GPU for non-gaming tasks, such as video playback, office productivity, or legacy software rendering, will find the 33 W TDP and IGP form factor to be advantageous for battery life and thermal management in portable devices. The 50th percentile standing suggests it is a median performer, meaning it is not a complete non-starter for light gaming, but users should have conservative expectations. For any workload requiring advanced rendering features, the lack of RT and tensor cores, combined with the DirectX 12 (11_0) limitation, indicates that the GPU is not a viable option for future-proofing or high-fidelity experiences. It is a pragmatic choice for basic computing needs, not for performance-oriented tasks.
Memory Subsystem — VRAM size/type, bus width, bandwidth and what it means for high resolutions
The memory subsystem of the GeForce 840A consists of 2 GB of DDR3 memory, which is a legacy memory type compared to the GDDR5 or GDDR6 used in higher-performance GPUs. The bus width is 64 bits, which is half the width of many entry-level discrete GPUs and a quarter of mainstream parts. This narrow bus, combined with DDR3 memory, results in a memory bandwidth of 16.02 GB/s. For context, this bandwidth is a critical bottleneck for higher resolutions; at 1080p or above, the GPU would be unable to feed the shading units with texture data and geometry quickly enough, leading to significant frame rate drops.
The memory clock is listed as 1001 MHz, with an effective data rate of 2 Gbps. This effective rate is the standard double data rate for DDR3, but the low bus width caps the total throughput. For high-resolution gaming, the 2 GB capacity is also a limiting factor; modern games at high resolutions often require more than 2 GB of VRAM for textures and buffers, leading to texture thrashing or reduced texture quality. The data suggests that the 840A is fundamentally constrained to 720p or lower resolutions with reduced settings, where the 16.02 GB/s bandwidth and 2 GB capacity can be adequately utilized. The pixel rate of 8.992 GPixel/s and texture rate of 17.98 GTexel/s further corroborate this, as these fill rates are insufficient for the demands of high-resolution displays.
