CTR and Gaming
CTR and Gaming
I'm still getting the hang of things, but I've been playing Battlefield 5 and checking Hwinfo. With my Ryzen 5600X, when I'm not using CTR, my cores stay relatively low—around 1000mhz, some at 2000-3000mhz, and one can hit up to 4000-4100mhz, though it never reaches boost speeds. The max temperature stays around 58 degrees, and the game runs smoothly without any problems. If I turn on CTR, all cores run between 4375-4550mhz, with one reaching 4800mhz, temperatures drop to the low 50s, and performance stays super smooth. My question is, what advantages do I actually gain by using higher clock speeds with CTR? I'm just trying to figure out the pros and cons.
Fps.
A certain duration is needed for a CPU to generate a frame. Every object requires positioning, address allocation, size definition, color settings, movement vectors, lighting effects, etc. The frequency at which a CPU can fully construct a frame within one second is measured by FPS.
The time required depends on various factors, mainly the number of instructions per clock cycle (IPC) and the core clock speeds in MHz. Higher MHz means more instructions processed, greater work accomplished, and frames completed more quickly.
The GPU can only render the image based on the data provided by the CPU, so if the CPU achieves 100 FPS, the GPU can display up to that rate.
Fps refers to the speed at which a CPU generates a frame. Every object needs precise positioning, address allocation, size, scale, color details, movement vectors, lighting effects, and more. The frequency at which a CPU can fully construct a frame in one second is determined by FPS.
The duration required for this process depends on various factors, mainly the number of instructions per clock cycle (IPC) and the core clock speeds in MHz. Higher MHz means more instructions processed, resulting in faster frame completion and quicker overall performance.
The GPU relies on the CPU to supply it with data, so its output is limited by the CPU's capability. If the CPU can achieve 100 FPS, the GPU can display up to that rate. Conversely, if the CPU only reaches 50 FPS, the GPU will reflect that limitation.
This difference becomes noticeable on high-refresh-rate displays like 60Hz monitors but is more significant on 144Hz screens. While it doesn't impact CSGO much, using boosted cores or higher settings can greatly enhance gameplay smoothness in titles such as BF5 or GTA V.
Enhanced cores provide an advantage, provided they operate within safe temperature limits. If performance is your priority and thermal comfort is not, investing in a better cooler is worthwhile. If you're indifferent, either setting will suffice.
In CTR, there are four CPU profiles based on the load percentage. Below 18%, the system runs at default settings, allowing ample flexibility to adjust clocks during idle or sleep phases. From 19-53%, P2 is applied, 54-72% uses P1, and 73% triggers the top profile. These profiles can be customized to suit your requirements and the CPU's performance capabilities.
Cool, thanks for the explanation. I had a feeling it was an FPS thing, with the cpu handling the FPS and GPU dealing with the eye candy. My monitor is only a 75Hz and I usually cap the graphics at that speed or just run it on freesync/Vsync.
Most screen tearing occurs near the limits of monitor refresh rates. It happens when you try to achieve 75fps on a 75Hz display, creating a mismatch. Instead of a full refresh, a new frame is shown over an existing one, leading to visual glitches. Therefore, it's recommended to adjust frame settings slightly higher than the monitor's refresh rate, such as 90fps, to avoid unintended tearing and maintain smooth playback.
