NVIDIA GeForce RTX 4090
About GPU
The NVIDIA GeForce RTX 4090 is an absolute powerhouse of a GPU that delivers stunning performance for any type of desktop user. With a base clock speed of 2235MHz and a boost clock speed of 2520MHz, this GPU is capable of handling even the most demanding tasks with ease and precision.
One of the most impressive features of the RTX 4090 is its massive 24GB of GDDR6X memory, which ensures that users can run even the most graphics-intensive applications without any lag or slowdown. Additionally, the 16384 shading units and 72MB of L2 cache further contribute to the overall performance and efficiency of this GPU.
In terms of real-world performance, the RTX 4090 delivers outstanding results across the board. In 3DMark Time Spy, it achieved an impressive score of 36248, showcasing its ability to handle complex rendering and graphics tasks with ease. Additionally, in popular games such as GTA 5, Battlefield 5, Cyberpunk 2077, and Shadow of the Tomb Raider, the RTX 4090 consistently delivered high frame rates, making for an incredibly smooth and immersive gaming experience.
However, it is important to note that the RTX 4090 has a TDP of 450W, which means that it requires a robust cooling system to prevent overheating. Additionally, the theoretical performance of 82.58 TFLOPS may be overkill for the average user and may not be fully utilized in everyday tasks.
Overall, the NVIDIA GeForce RTX 4090 is a truly remarkable GPU that sets a new standard for desktop graphics performance, making it an excellent choice for professional workloads and enthusiastic gamers alike.

Tensor Cores
?
Tensor Cores are specialized processing units designed specifically for deep learning, providing higher training and inference performance compared to FP32 training. They enable rapid computations in areas such as computer vision, natural language processing, speech recognition, text-to-speech conversion, and personalized recommendations. The two most notable applications of Tensor Cores are DLSS (Deep Learning Super Sampling) and AI Denoiser for noise reduction.

TMUs
?
Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth
?
Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Pixel Rate
?
Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.
443.5 GPixel/s
Texture Rate
?
Texture fill rate refers to the number of texture map elements (texels) that a GPU can map to pixels in a single second.

FP16 (half)
?
An important metric for measuring GPU performance is floating-point computing capability. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy.

Miscellaneous
SM Count
?
Multiple Streaming Processors (SPs), along with other resources, form a Streaming Multiprocessor (SM), which is also referred to as a GPU's major core. These additional resources include components such as warp schedulers, registers, and shared memory. The SM can be considered the heart of the GPU, similar to a CPU core, with registers and shared memory being scarce resources within the SM.

Shading Units
?
The most fundamental processing unit is the Streaming Processor (SP), where specific instructions and tasks are executed. GPUs perform parallel computing, which means multiple SPs work simultaneously to process tasks.

ROPs
?
The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
