Teraflop is a measurement of the number of calculations a system can perform in a second. It is an important metric of PC performance. A teraflop of TFLOP is trillions of calculations per second.
The performance of a PC is not easily quantified. The PC, which works tremendously for a certain task, might just be an average PC for other tasks, but the upcoming desktops might be more capable of finishing the heavy-duty tasks than the previous generation supercomputers. Also, the features like the clock speeds, core counts, and even the instructions per second are not always comparable.
FLOPS or the floating-point operations per second, or TFLOPS, are the measurements that, in order to give a firmer measurement, can cross generations and even different components.
Teraflop and its Features
The floating-point arithmetic is a computational method that takes a measure between accuracy and performance. FLOPS is basically a measurement of how many of the calculations, as mentioned above, you can make per second. It includes half-precision (16-bit), single-precision (32-bit), and double-precision (64-bit).
Every task makes use of a varied type of FLOPS like the gaming task focuses more on single-precision FLOPS, AI computation, and various other scientific tasks that use double-precision. The modern device use Teraflops to measure their performances. A TFLOP represents one trillion calculations per second.
Over the years, TFLOPs are one of the most significant methods to measure performance, especially the performance of the graphic cards. It was in 2008 when AMD released its first graphics card with TFLOPS capabilities.
But since then, various new generation graphics cards and game consoles have been released, which are far more capable than the previously discussed AMD’s graphic card. The new generation graphics card and gaming consoles can efficiently deliver performance more significant number of times compared to the TFLOPs of the previous generation GPUs. Like the all-new RTX 3090 has around 36 TFLOPS of shader performance, mobile graphics like Radeon Pro 5600M (the one found in MacBook Pro) have over 5.3 TFLOPS.
PS5 Teraflops vs. Xbox Series X Teraflops
The all-set next-generation gaming consoles from Sony and Microsoft would be the most capable gaming consoles. Both the PS5 and the Xbox Series X consoles will use a custom Accelerated Processor Unit of AMD that will combine the eight Zen 2 CPU cores and a custom RDNA2 graphics core. Having such a massive hardware structure, TFLOPS becomes a useful way of measuring their capabilities. The PS5 has 10.28 teraflop ratings for its graphics processor, while the Xbox series X might have around 12 teraflops.
Compared to the previous generation gaming consoles, this is a drastic advancement as the Xbox One X was only capable of up to 6 teraflops with a single point precision, and the PS4 Pro was able to handle only over 4.2 teraflops.
The Limitations of Teraflops
TFLOPS can be considered as only one aspect of a graphics card or a gaming console’s performance. They do not have any relation with the CPU architecture, clock speed, process node, core count, memory speed, or pixel fill rate, or more. We can consider it a useful metric, but that’s not all-encompassing in itself. You can do that when it comes to gaming; there are various other factors that affect performances of the real-world gaming on the Graphics Processing Unit. The factors can be gaming systems itself, CPU dependency, storage and system’s memory, etc. The bottlenecks of the components can lead to slowing down the entire system; not every aspect of a specific game relies equally on each component.
Some factors also depend on the game settings the user chooses. The idea here to express is that no matter if you have the most powerful graphics card of the world, along with the highest TFLOPS accordingly. Still, if you will play a game with a 1080p resolution, it will not be possible for your system to use the full efficiency of your GPU, and it would not be able to use the maximum performance of the TFLOPS. Everything used would be somewhere over a mid-range GPU, which has a much lower TFLOPS performance.
So, these were the details regarding Teraflops that you should know, including its features, advantages as well as its limitations.
