NVIDIANVIDIA GeForce GTX 850A Specifications
GeForce GTX 850A GPU Core
Shader units and compute resources
The NVIDIA GeForce GTX 850A 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.
GTX 850A Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce GTX 850A'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 GTX 850A by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce GTX 850A Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce GTX 850A'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 GTX 850A by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the GTX 850A, 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.
GTX 850A Theoretical Performance
Compute and fill rates
Theoretical performance metrics provide a baseline for comparing the NVIDIA GeForce GTX 850A 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.
Maxwell Architecture & Process

The NVIDIA GeForce GTX 850A is built on NVIDIA's Maxwell 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 GTX 850A will perform in GPU benchmarks compared to previous generations.
NVIDIA's GeForce GTX 850A Power & Thermal
TDP and power requirements
Power specifications for the NVIDIA GeForce GTX 850A 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 GTX 850A to maintain boost clocks without throttling.

About NVIDIA GeForce GTX 850A
The NVIDIA GeForce GTX 850A is an end-of-life graphical processor from the GeForce 800A generation, built around the GM107 chip and Maxwell architecture. TSMC manufactures it on a 28 nm process with 1,870 million transistors in a 148 mm² die, producing a transistor density of 12.6M/mm². The product sequence places it after GeForce 700A and before GeForce 900A, with a release date of 2014-03-16. The record identifies a 45 W TDP, an IGP slot width, and Portable Device Dependent display outputs. Its benchmark array is empty, the average benchmark score is 0, and its percentile rank among all GPUs is 50.
Benchmark Performance
The benchmarks array is empty, so the fact pack does not contain any frame-rate or synthetic workload results. The average benchmark score field is set to 0; this is an empty aggregate rather than evidence of a measured zero in the database. The only relative metric is the 50th-percentile rank against all GPUs, which places this part at the median of the record set. Without named nearestRivals, there are no deltaPct figures to quote.
The clock profile is simple: base 902 MHz and boost 902 MHz, with no separate game clock listed. Using that 902 MHz clock, 640 shading units translate to 1,154.6 GFLOPS of FP32 compute, 40 texture units produce 36.08 GTexel/s, and 16 ROPs generate 14.43 GPixel/s. These figures describe a compact Maxwell part built around low power rather than peak throughput. The 45 W TDP reinforces that interpretation, since the compute setup is modest in absolute terms and the record does not include a higher sustained game clock.
Because no benchmark samples are present, the percentile value cannot be cross-checked against measured workloads. The result is a GPU whose structural performance is known, but whose real-world score placement is not represented by any sample data. The absence of a game clock also means no separate boosted gaming frequency is documented.
Memory Subsystem
The memory subsystem consists of 2 GB of DDR3 on a 128-bit bus. The memory clock is 900 MHz, listed at 1800 Mbps effective, and aggregate bandwidth is 28.80 GB/s. That bandwidth figure is the only memory throughput value in the record, and it represents a modest data path for high-resolution work.
The 2 GB capacity sets a hard working-set limit for textures, frame buffers, and geometry data. At higher resolutions, the combination of a 2 GB capacity and 28.80 GB/s bandwidth will tend to constrain performance before the 1,154.6 GFLOPS compute capacity is fully occupied. The 128-bit bus width, DDR3 type, and 900 MHz memory clock are all consistent with that bound.
The fact pack provides no resolution-specific benchmark data, so the exact resolution at which memory becomes the limiting factor cannot be quantified from this page. However, the data clearly shows a memory interface designed for moderate data movement, not for large high-resolution frame buffers. The effective 1800 Mbps memory transfer rate is low enough that even the 14.43 GPixel/s pixel fill rate may outstrip the memory subsystem in heavy fill workloads.
Who Should Consider It
The GTX 850A is recorded with an IGP slot width and Portable Device Dependent outputs, which points to portable systems rather than desktop add-in boards. The 45 W TDP reinforces that placement in the data. Any consideration of this GPU should account for the empty benchmark list: there are no measured scores to validate a particular resolution or quality preset.
Based on the listed memory and compute figures, the target usage is workloads that stay within 2 GB of memory and fit within 28.80 GB/s of bandwidth. The 640-shader Maxwell unit can deliver 1,154.6 GFLOPS, but that throughput is paired with 16 ROPs and 40 TMUs, so heavy fill-rate tasks will be limited by the 14.43 GPixel/s and 36.08 GTexel/s ceilings. Users should expect a moderate-featured operating point, not an extreme-resolution one.
The data also shows DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.4 support, so the GPU can be relevant in API-constrained contexts. For portable devices where a 45 W TDP is acceptable, the GTX 850A may be a reasonable fit for modest workloads. The 50th-percentile placement is neutral, but the memory and compute characteristics are the more meaningful decision inputs in the absence of benchmark scores.
How It Compares
The nearestRivals array in the fact pack is empty. Therefore, this page has no rival names, scores, or deltaPct values to present, and no percentage-based competitor comparison is possible.
The only placement references are structural: the GPU is part of the GeForce 800A generation, with GeForce 700A as predecessor and GeForce 900A as successor. The 50th-percentile field is a database-wide position, not a head-to-head result against those products. The production status is End-of-life, and the release date is 2014-03-16.
With no rival rows, any assertion about being faster or slower than a specific competitor would be unsupported by the fact pack. The predecessor and successor fields establish the product order but do not provide performance deltas. The data does not include clocks, memory sizes, or throughput values for those adjacent products, so no comparison can be made beyond naming the sequence.
Ray Tracing and Feature Set
The record lists rtCores and tensorCores as missing for this GPU, so no dedicated ray-tracing cores or tensor cores are specified in the data. The feature set is therefore defined by the Maxwell architecture and the API support fields.
DirectX 12 is listed as 12 (11_0), which indicates the DirectX 12 API with a hardware feature level of 11_0. OpenGL 4.6 and Vulkan 1.4 are also listed. The GPU uses a PCIe 3.0 x16 bus interface. Display outputs are Portable Device Dependent, meaning the exact connectors and supported display paths depend on the portable device into which the GPU is integrated.
With no RT or tensor core entries, the Maxwell configuration is limited to the traditional shader pipeline: 640 shading units, 40 TMUs, and 16 ROPs. The API field shows modern API support, but the hardware feature level for DirectX remains 11_0. This is a useful distinction because the API version alone does not imply full DirectX 12 feature support.

Power and Cooling
The fact pack lists a 45 W TDP as the only power figure. There are no power connector entries and no suggested PSU value, so a clear desktop power-supply requirement cannot be derived from the record.
The slot width is IGP, and the display outputs are Portable Device Dependent; these data fields describe a GPU intended for integration into portable devices rather than a standalone card with its own cooling solution. No cooler dimensions, length, height, or width values appear in the record.
The 45 W envelope is the sole thermal indicator. The data does not specify heatsink size, fan configuration, or chassis clearance. The absence of power connectors is consistent with the IGP form factor, and the lack of a suggested PSU further separates this part from conventional desktop GPU power planning.
