GeForce 820A GPU Core
Shader units and compute resources
The NVIDIA GeForce 820A 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.
820A Clock Speeds
GPU and memory frequencies
Clock speeds directly impact the GeForce 820A'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 820A by NVIDIA dynamically adjusts frequencies based on workload, temperature, and power limits to maximize performance while maintaining stability.
NVIDIA's GeForce 820A Memory
VRAM capacity and bandwidth
VRAM (Video RAM) is dedicated memory for storing textures, frame buffers, and shader data. The GeForce 820A'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 820A by NVIDIA Cache
On-chip cache hierarchy
On-chip cache provides ultra-fast data access for the 820A, 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.

Nearby PerformersAbout NVIDIA GeForce 820A
The NVIDIA GeForce 820A is an end-of-life GPU in the GeForce 800A generation. Its GF117 chip is built on Fermi 2.0 architecture and fabricated by TSMC on a 28 nm process. The die measures 116 mm² and contains 585 million transistors, giving a transistor density of 5.0M / mm². The only benchmark score in the FACT PACK is a Geekbench OpenCL result of 2983, which places the GPU at the 18th percentile among all tracked GPUs. The slot width is IGP, and display outputs are described as Portable Device Dependent.
Memory Subsystem
The memory subsystem consists of 1024 MB of DDR3 on a 64-bit bus. The memory clock is 1001 MHz, listed as 2 Gbps effective, and the resulting bandwidth is 16.02 GB/s. This is a small memory footprint and a narrow data path, so high-resolution workloads face capacity and bandwidth constraints. The framebuffer cannot hold large high-resolution texture sets without spilling, and the 16.02 GB/s bandwidth limits how quickly pixel and texture data can move. The pixel rate is 2.500 GPixel/s and the texture rate is 10.00 GTexel/s, so the memory interface is consistent with the compute resources rather than a hidden strong point. Base and boost clocks are not listed in the FACT PACK; the memory clock is the only clock data available. For high-resolution rendering, the 1024 MB capacity and 16.02 GB/s bandwidth are the primary gates. A larger framebuffer would require more bandwidth to fill efficiently, and this part’s 64-bit path means every memory transaction is narrow.
Ray Tracing and Feature Set
The ray tracing core count is null and the tensor core count is null, so no dedicated ray tracing or tensor hardware is specified for this part. The API table lists DirectX 12 (11_0) and OpenGL 4.6; Vulkan is null. The underlying Fermi 2.0 architecture is the only architecture label in the data, and the supported feature level is explicitly DirectX 12 (11_0). Compute resources include 96 shading units, 16 TMUs, and 8 ROPs. FP32 throughput is 240.0 GFLOPS. Without RT cores or tensor cores, the available acceleration paths are the shading units and fixed-function texture and pixel units. The texture rate of 10.00 GTexel/s and pixel rate of 2.500 GPixel/s describe what those units can deliver. The absence of a Vulkan entry is important for any workload that relies on Vulkan rather than DirectX or OpenGL.
Benchmark Performance
The Geekbench OpenCL score is 2983, and the average benchmark score is also 2983 because the FACT PACK lists a single test. The percentileVsAllGpus value is 18, meaning the 820A sits below most entries in the database. The nearest rivals form a tight cluster. The GeForce GT 730M has an average score of 2975, a 0.3% deficit relative to the 820A. The GeForce GTX 860M averages 2959, a 0.8% deficit. The GeForce GTX 750 Ti averages 3016, which is 1.1% higher than the 820A. The GeForce RTX 4060 Ti 8 GB averages 2913, a 2.4% deficit. These deltas are all small, but the largest is the 2.4% gap in favor of the 820A over the RTX 4060 Ti 8 GB. That result is counterintuitive given the naming hierarchy, and it suggests this particular OpenCL workload is not a comprehensive measure of GPU capability. Still, the 18th percentile is a clear placement: the 820A is not a high-scoring part in the database.
Power and Cooling
TDP is 15 W. Slot width is IGP, and the power connector field is None. The suggested PSU field is null, so the database does not specify a power supply requirement. This aligns with a low-power integrated part: no auxiliary connectors are needed, and the power draw is modest. The bus interface is PCIe 2.0 x16. Display outputs are Portable Device Dependent. A 15 W GPU with no power connectors is straightforward to power from the platform, and cooling information is not listed directly, but the low TDP implies a small thermal solution. The absence of a suggested PSU is consistent with a part that is not expected to be installed as a discrete card requiring a dedicated power budget.
How It Compares
Compared with the GeForce GT 730M, the 820A is 0.3% ahead in OpenCL performance. The 2983 versus 2975 delta is small enough to call the two effectively tied in this test.
Compared with the GeForce GTX 860M, the 820A leads by 0.8%, with the GTX 860M’s average at 2959. The model-number ordering would suggest the opposite, so the specific test workload matters.
Compared with the GeForce GTX 750 Ti, the 820A trails by 1.1%. The 750 Ti’s average of 3016 is the only listed rival score above 2983, making it the nearest competitor that beats the 820A.
Compared with the GeForce RTX 4060 Ti 8 GB, the 820A leads by 2.4%, since the RTX card’s average is 2913. This is the largest delta in the group and reinforces the single-test nature of the comparison.

Who Should Consider It
The GeForce 820A is suited to workloads that fit within a 1024 MB DDR3 framebuffer and do not stress its 16.02 GB/s bandwidth. The 18th percentile rank means it will not satisfy demanding high-resolution rendering. It is better positioned for lower-resolution or lighter scenes where 2.500 GPixel/s and 10.00 GTexel/s are sufficient. The 240.0 GFLOPS FP32 value provides a compute reference; heavy compute tasks are outside its intended tier. Software must run through DirectX 12 (11_0) or OpenGL 4.6, since Vulkan is absent. The low 15 W TDP and no power connectors make it easy to integrate into portable-device designs. The part is end-of-life, and the successor GeForce 900A is the named upgrade path in the data.
